第八章 报警
T he alarms used by the ZS3000 thyristor unit protect the thyristors and the installation against abnormal operation and give the user information on the type of failures that have occurred.
ZS3000晶闸管单元使用的报警可以保护晶闸管的错误动作,并且 提供发生的故障信息。
Danger !
危险!
Alarms cannot be used to replac e person nel protection.
报警不能用来代替人员防护。
A LARM STRATEGY
报警原理
T he ZS3000 thyristor unit alarms are entirely managed by the microprocessor of the driver board which retransmits its data (alarms enabled or not) using the display on the thyristor unit front panel and alarm relays.
ZS3000晶闸管单元的报警完全由触发板的微处理器管理,而报警数据和信息由前面板的数码
管显示和报警继电
器指示。
T he enabled state of all the alarms is indicated by the front panel display and alarm relays .
所有使能的报警状态全部由前面板显示和报警继电器指示。
T he highest level alarms detect the following failures:
高级报警检测故障如下:
• absence of one or more sup ply phases
电源缺一相或几相
• over-current in Burs t firing modes
调功模式过流
• under-voltage

欠压
• thyristor short-circuit
晶闸管短路
• external meas urement signal failure.
外部输入信号错误
• neutral failure (fuse b low-out on the driver board).
不确定故障(触发板保险烧掉)
Th e detection of one of these failures causes the thyristor unit operation to be inhibited
这些故障可以引起晶闸管单元停止工作。
T he low level alarms monitor:
低级报警检测:
• the over-voltage
过压
• the cur rent unbalance
电流不平衡
• the first overcurrent in Burst firing mode.
调功模式过流
A LARM RELAYS
报警继电器
T he alarm relays are located on the driver board:
报警继电器安装在触发板上: th e relay for all the other alarms (general alarm relays).
任意报警发生,继电器都会动作
T he switch cut-off capacity is2 A (250 Vac or 30 Vdc).
报警继电器的开关容量为2A . (250 Vac or 30 Vdc).
T he switch operating voltage must never be greater than 250 Vac.
报警继电器的开关的电压不能超过250 Vac。

DANGER!
危险!
The controller must be maintained by personnel qualified and trained to work with low voltage electrical equipment in an industrial environment.
调功器的维护必须由受过专业训练的人员完成,而且其要有在工业 现场环境中
的低压电器设备的操作经验。
T he user’s installation must be protected upstream (non high-speed fuses, thermal or electromagnetic circuit breaker, suitable fuse-isolator) and mus t comply with current standards.
用户的安装必须有隔离断路器的 保护,而且要符合电流标准。
F USES

T hyristor protection
晶闸管保护
T he thyristors in the ZS3000 series controllers are protected in the following way:
ZS3000系列控制器的晶闸管保护方式如下:
· external high speed fuses against overcurrents (e xcept for short-wave infrared applications)
额外的快速熔断保护过流
· RC snubbers and MOVs (var istors) protect against over-fast voltage variations and transient overvoltages when the thyristors are not conducting.
阻熔吸收保护晶闸管未导通
时的瞬间过压。

DANGER!
危险!
High-speed fuses ar e used onl y for the protection of thyristors against large amplitude overloads.
快速熔断只能保护晶闸 管的过流。
Under no circumstances should these h igh-speed fuses be used to protect the installation.
不能将快速熔 断用作隔离断路器的保护装置。
To protect the thyristors in the ZS 3000 series, 3 fuses and a tri-polar fuse-holder must be used.
为了保护ZS3000系列的晶闸管,每相均有快速熔断。
SERVICING
维修
ZS3000 controllers must be mounted with the heatsink positioned vertically, with no obstructions above or below which could inhibit or impede airflow.
ZS3000控制器必须垂直安装,在其上下面都没有阻碍物阻碍空气流通。
Attention!
注意!
If several units are mounted in the same cabinet, they should be arranged in such a way that air expelled from one cannot be drawn into the unit located above it.
如果一个控 制柜中安装多个调功器单元,它们的安装排列方式应以不影响空
气循环流通的原则。
In order to ensure correct cooling of the unit, users are advised, depending on the degree of environmental pollution, to regularly clean the heatsink and the protective fan guard.
为了保证调功器单元的正常冷却,建议用户,根据环境污 染情况,定期的清洁受热面,保护风机正常。
DANGER!
危险!
Cleaning shou ld only be c arried out when the controller supply is disconnected and at least 15 minutes after it has ceased operating.
清洁工作必须在控制器切断电源停止工作15分钟以后进行。
Every six months check that the screws of the power and safety earth cables are correctly tightened .
每6个月检查动力线和接地 线的螺栓是否紧密。
