General description

Recloser principle and design

Reclosers are used in distribution systems. Like circuit breakers, reclosers are used to make and break normal and fault currents. Reclosers are fully equipped with sensors and a controller to provide a means of protection and control. In case of a line fault, reclosers can break and make currents several times, thus avoiding longer network interruptions due to temporary faults.

Type SDR vacuum reclosers are outdoor devices designed for repeated opening and reclosing in case of a fault, as specified in ANSI/IEEE standard C37.60.

The vacuum recloser consists of two main components: the recloser switch and the control cubicle.

This instruction manual covers information related to the recloser switch unit and the control cubicle. The instruction manual does not cover the controller or related accessories (for example, modems).

For information pertinent to the controller, refer to the Siemens Protection

Devices Limited instruction manuals.

The manufacture, design and testing of the vacuum recloser is based on current regulations and standards and state-ofthe-art technology. The product conforms to the following standards:

ANSI/IEEE C37.60/IEC 62271-111

IEC 60255-11

IEC 60255-21-1 Class I



IEC 60255-22-1 Class III

IEC 60255-22-2 Class IV

Note: IEEE C37.60 and IEC 62271-111 are the same document (dual logo IEEE and

IEC).


Recloser switch unit with encapsulated vacuum interrupter

The recloser switch unit is comprised of the poles, the operating mechanism and the operating mechanism housing. The side sections with the support feet form the base of the recloser switch unit. The switch unit can be secured to the pole mounting or substation frame.

Pole

The poles are molded using cycloaliphatic epoxy resin specially designed for outdoor use. The vacuum interrupters are encapsulated in the pole units. In addition, each pole contains a current transformer and may also contain an optional voltage sensor.

The sequence of the poles is C - B - A

(sequence left to right when viewed from the lower terminal side of the recloser switch unit - rear of recloser) (refer to

Figure 4). This is marked on the operating mechanism housing by identification indents (A = 1 indent, B = 2 indents and C

= 3 indents). This sequence identifies the currents IA, IB and IC of the controller.

Current transformers (CTs)

The type SDR vacuum recloser is equipped with one integrated current transformer per pole. The current transformer is the conventional type (iron core magnetic) and has a ratio of 800 A:1 A. It is for protection purposes and optimized for operation with the controller (see control cubicle on page 13). The secondary signal is based on IEC 60044-1.

The secondary wires of the CT are connected to a varistor for each pole in the switch unit. This prevents the occurrence of high voltages (due to open-circuit CT secondary) if the control cable is removed while the switch unit is in operation. Do not disable the varistor circuit.

The signal transfer from the CTs to the controller is by the control cable. A separate cable is not required.

Voltage sensor (optional)

The SDR vacuum recloser can be equipped with integrated resistive voltage sensors

(optional). The integrated resistive voltage sensors have a high level of accuracy and are used both for measurement and protection purposes. The ratio is adapted to operation with the controller (see control cubicle on page 13) and provides a

110 V/√3 secondary signal with rated primary voltage applied to the recloser.

No other controller should be used for the voltage measurement as the sensor design and controller design are coordinated. An optional separate sensor cable equipped with special screening (shield) is used for the signal transfer from the voltage sensors to the controller. This results in a high level of accuracy and protection against disturbances. The sensor cable is connected at the back of the operating mechanism housing next to the control cable.

The secondary wires of the voltage sensors are connected to a varistor for each pole in the switch unit. This prevents the occurrence of high voltage on the sensor cable if the sensor cable is removed while the switch unit is in operation. Do not disable the varistor circuit.

Operating mechanism

The operating mechanism for the vacuum interrupters is located in a metal housing.

To meet the required fast reclosing cycles, a magnetic actuator with capacitors as energy storage drives the switch unit. A gang-operated mechanism connects the magnetic actuator with the vacuum interrupters.

The operating mechanism is equipped with anti-condensation space heaters. It is operated together with the heating in the control cubicle and controlled by a thermostat.

A mechanical position indicator is easily visible from the ground and shows the current switch position of the recloser

(open = green, closed = red). The colored display is reflective in the dark when using a flashlight.

Lockout handle

A lockout handle with ring protrudes from the operating mechanism housing. The ring is colored bright yellow and is therefore easily seen.

By pulling the lockout handle, the recloser opens and remains locked in this position.

The locking has a dual electrical effect; it locks out both the controller and the electronics. It also mechanically locks the magnetic actuator.

As long as the lockout handle is pulled out, it is not possible to close the switch unit electrically, whether locally or from a remote location. The interlocking is not reset until the lockout handle has been completely pushed in. After this, the switch unit can be closed electrically, either locally or from the control room.

The switching is described in the Operation section of this instruction manual (see page 28).

Note: The lockout handle must be fully pushed in or the interlocking will prevent closing of the recloser.

Pole-mounting frames

A pole-mounting frame is used to install the recloser switch unit on an overhead line pole. The mounting frames can also optionally accommodate surge arresters and source side external voltage sensors.

The following pole-mounting frames are available:

Design 1 with provisions for line-side external voltage sensors and line- and load-side surge arresters (see Figure 9)

Design 2 with provisions for load-side surge arresters (see Figure 10).

It is recommended that at least two 0.75 inch bolts be used as king bolts to secure the pole-mounting frame to the pole.

For installing within substations, a special frame is available (see installing at the substation on page 23).

Control cubicle

The control cubicle is equipped with integrated pole-mount brackets. It can be installed on the recloser pole or substation frame at an operating height as preferred by the user.

The control cubicle is equipped with a lockable door with provision for a padlock.

Behind the door is a swing frame, which contains the controller, miniature circuit breakers and a general power outlet (GPO) for a laptop. Behind the swing frame, there are printed circuit boards (PCB), rechargeable batteries and wiring connections.

The control cubicle is equipped with a thermostat-controlled anti-condensation heater (space heater). The thermostat also controls the space heater in the switch unit. Each heater consists of two resistors.

The heating is switched off above approximately 40° C.

Discharge switch for the capacitors

The discharge toggle switch on the switch unit driver (SUD) module/printed circuit board PCB2 serves to discharge the capacitors. In the "discharge capacitors" position (right position), the capacitor charging operation is turned off and the capacitor discharged via a resistor – discharge of the capacitors takes roughly one minute.

In the "operating" position (left position), as shown in Figure 15, the red discharge

LED next to the switch shows the voltage at the capacitor is more than 40 V (LED on). Work on the capacitor should only be performed once the LED no longer illuminates.

For normal operation, the switch must be brought into the "operating" position (left position) – however, the LED does not light up during operation.

Could result in serious injury or equipment malfunction.

For maintenance work, the toggle switch on PCB2 must be in the

"discharge capacitors" position (pointing right). Do not work on the capacitor circuits when the red discharge LED is lit.

For normal operation, the toggle switch on PCB2 must be in the

"operating" position (pointing left).


Auxiliary power supply

The control cubicle works on an internal

48 Vdc bus, which is provided by rechargeable batteries as an element of an uninterruptible power supply. This internal bus is energized from PCB1, which charges the batteries and the capacitors. Charging of the batteries is automatically compensated for temperature.

PCB1 is supplied by auxiliary power provided on site, either through a usersupplied low-voltage supply or individual power transformer (optional). This supply needs to be connected to terminals on terminal block X1. PCB1 is then protected by the miniature circuit breaker CB1.

The same supply is used for the heaters and the general power outlet (GPO). They are protected by miniature circuit breaker

CB2.

Rechargeable batteries

Four-12 V batteries are supplied with the recloser. They are to be installed in series on site (see Installation and commissioning on page 22). The batteries are protected by the miniature circuit breaker CB3. The batteries ensure minimal stand-by operation for 48 hours at 20° C from a fully charged initial condition.

If miniature circuit breaker CB3 opens or trips, it disconnects the control power for the controller and the controller will neither operate the recloser nor protect the network. Control and protection functions restart automatically by closing

CB3.

If the batteries are not in use, they should be recharged after six months.

User interfaces

The following interfaces are available for purchaser use:

Three binary inputs (BI) and three binary outputs (BO) are provided on the terminal rail on the rear of the controller, as identified on the wiring diagrams. The binary inputs are switched to 48 V (wet contacts). The binary outputs are potential-free (dry contacts).

On the front of the controller is a USB interface for connecting a laptop computer to set parameters, download events and update firmware.

For connection to a remote terminal unit

(RTU) or supervisory control and data acquisition (SCADA):

RS/EIA-485 port at rear

Connection for IRIG-B signal at rear

(optional)

Optical ports (Rx/Tx) (optional)

RS/EIA-232 port at rear (optional).

Communication protocols DNP3, Modbus and IEC 60870-5-103 are supported through the communication interfaces.

An optional power supply can be provided for additional communication modules

(radio unit or modem). It is directly connected to the auxiliary power supply through CB2 and not connected to the uninterruptible power supply.

Additional BI/BO may be provided as an option.

Figure 28: Connection of cables and grounding (earthing) of recloser

For grounding (earthing) to be effective, the cables (control and optional sensor cable) must be installed as close together as possible with the ground (earth) conductor (see Figure 28). Ideally they should be bundled together.

Connect cables between recloser switch unit and control cubicle

1. Connect control cable to the recloser switch unit and control cubicle. The plug-in connection on the control cable is protected against polarity mismatch.

2. Secure plugs to prevent them from loosening using the locking clip.

3. Connect sensor cable (optional) to the recloser switch unit and control cubicle. The plug-in bolted joint on the sensor cable is protected against polarity mismatch.

4. Check plugs are inserted correctly and secured.

5. Fasten the control and sensor cable to the pole using appropriate means (for example, cable ties).

6. Loop and fasten excess lengths of cable in the area of the pole-mounting frame.

Operation

The recloser is just one device in a distribution system. The user of the recloser must set the controller protection and control parameters to suit the user’s distribution system needs, and to provide reliable, safe and trouble-free operation of the recloser.

Safety instructions for operation

In addition to the local safety rules and work practices, special precaution must be taken:

The accessories required to operate the recloser must be stored in a clean location and must be checked regularly for completeness and good condition.

All keys must be accessible only to the authorized operating personnel.

No modifications should be made to the recloser. This includes, but is not limited, to removal of parts, opening the operating mechanism housing and any modification (including adjustment) of the drive system of the recloser.

The control cable and the optional sensor cable must not be removed during operation. Removing these cables would mean no further electrical operation could be performed and no measurement values or other signals could be sent from the recloser switch unit to the controller.

Switching

Switching comprises electrical switching

(remote and/or local operation) and mechanical switching (by means of the lockout handle).

Switching is carried out automatically by the controller to protect the network by remote control or manually on site.

Local operation

Local operation describes the manual electrical switching of the recloser on site.

Manual switching using the lockout handle is discussed in the Lockout operation section of this instruction manual on page

30.

These switching actions can be carried out from the control cubicle using the Close/

Open pushbuttons or using the function keys on the controller.



Always de-energize and ground the equipment and all terminals before performing any work near high-voltage conductors.

Work on the recloser switch unit or the control cubicle should be performed only by qualified personnel.

Do not open the inner panel of the control cubicle, as interior parts energized at voltages higher than 50 V are present.

Do not disconnect control or sensor cables while recloser is energized, as connectors contain energized parts.

Operation

Figure 33: Lockout handle with ring for manual operation (pushed in, normal operation)

Figure 34: Lockout handle with ring for manual operation (pulled out, recloser open and locked out)

Lockout operation

Lockout operation combines the mechanical tripping / opening of the recloser and the interlocking to inhibit subsequent closing of the recloser.

The lockout can also be operated when under load.

For three-pole recloser, all three poles will be operated simultaneously by the mechanical link of all poles.

Open the recloser

1. Using a hot stick or suitable rod from the ground, pull down the lockout handle until it reaches the end (lower) position.

The recloser opens. By operating the lockout mechanism, the recloser is opened mechanically and locked in this position.


The green LED next to the function key F1 in the controller indicates the switch unit has operated.

The switch action is completed.

As long as the lockout handle is pulled out, it is not possible to close the recloser electrically, whether locally or from a remote location.

Closing the recloser electrically from the controller

1. Using a hot stick or suitable rod from the ground, push the lockout handle back in completely.

2. Press the F2 key.



After switching, the red LED next to the function key F2 indicates the switch position has been reached.




Closing the recloser electrically using the Close/Open pushbuttons

Note: The lockout handle needs to be pushed back completely. Otherwise, the interlocking still prevents closing.

Operation

Malfunction

Failure of the auxiliary power supply

"Aux power OK" does not light up

Heating and GPO socket do not work

Failure of batteries

Closing of the recloser is blocked

Incomplete recloser cycle > only switching off is possible

Remedy

The auxiliary power supply is protected by a miniature circuit breaker in the front plate of the swing frame

1. Check miniature circuit breaker CB1 and switch on if necessary.

2. Check the status of the external auxiliary power supply.

Check miniature circuit breaker CB2 and switch on if necessary.

The batteries are protected by a miniature circuit breaker

(behind the swing panel).

1. Check miniature circuit breaker CB1 and switch on if necessary.

2. Check the battery status via the controller menu and replace batteries if necessary.

Technical data

Current transformer data

The current transformer has a ratio of

800 A:1 A.

Voltage sensor data (optional)

The ratio of the voltage sensors is adapted to operation with the controller and provides a 110 V/√3 secondary signal when the recloser is energized at rated maximum voltage.

Ambient conditions

The type SDR vacuum recloser is suitable for use under "usual service conditions" as given in IEEE standard C37.60/

IEC 62271-111, as follows:

Ambient temperature -30° C to 55° C

(standard)

Ambient temperature -40° C to 55° C

(optional)

Solar radiation <1,120 W/m 2

Altitude <1,000 m or less

Altitude correction factor

The insulating capability of insulation in air decreases as the altitude increases due to the reduced air density. The rated lightning impulse withstand voltage values (see

Table 5) are valid according to IEC 62271-1 and IEEE C37.60 up to an installation height of 1,000 m above sea level. Above a height of 1,000 m, the insulation level must be corrected in line with Figure 35.

Example: At 2,500 m altitude, a unit rated

110 kV BIL under "usual service conditions" will have a lightning impulse withstand capability of:

Compare the correct voltage of the recloser. (For example, compare the rated voltage of the recloser

(see Figure 41) with the system voltage. Contact

Siemens customer service if the voltage is incorrect at +1 (800) 347-6659 or +1 (919) 365-2200 outside the U.S..)

Determine the correct auxiliary voltage. Digit 11 of the order number indicates the auxiliary voltage required:

3 corresponds to 110 Vdc

4 corresponds to 220 Vdc

5 corresponds to 110 / 220 Vac

6 corresponds to 220 / 240 Vac

9 corresponds to 110 / 120 Vac with auxiliary transformer.

Contact Siemens customer service if the auxiliary voltage is incorrect at +1 (800) 347-6659 or

+1 (919) 365-2200 outside the U.S..
