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 60255-21-2 Class I

General description
Current transformers (CTs)
Operating mechanism
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 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 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)
Lockout handle
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.
A lockout handle with ring protrudes from
the operating mechanism housing. The
ring is colored bright yellow and is
therefore easily seen.
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.

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.
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.
Recloser
position
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.

Operations counter
A mechanical operations counter is
installed at the bottom of the recloser
switch unit. It records the total number of
switching operations independently of the
electrical recording in the controller. The
operations counter is used to keep track of
the total number of operations of the
switch unit in case the controller is
replaced or the electronic counter is reset
in the controller.

(operating position)
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.

General description
Auxiliary power supply
User interfaces
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.
The following interfaces are available for
purchaser use:
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.
Additional BI/BO for Rear communication

Technical data
Current transformer data
Altitude correction factor
The current transformer has a ratio of
800 A:1 A.
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.
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
Example: At 2,500 m altitude, a unit rated
110 kV BIL under "usual service conditions"
will have a lightning impulse withstand
capability of:
