为了确保小型开关柜不受外界因素的干扰,厂家通常都会为其配备相应的闭锁装置,但并非任意闭锁装置都适用于开关柜的,还必须满足一系列的技术要求,包括了开关柜闭锁装置的功能、使用方式等。

In order to ensure that the small switch cabinet without the interference of external factors, manufacturers are usually equipped with corresponding locking device for it, but not any locking device are suitable for switch cabinets, you must also meet the requirements of a series of techniques, including the switch cabinet locking device function, the way of use.


贵阳开关柜提醒既然要为小型开关柜设置闭锁装置,那么它至少要具备五防功能,除防止误分、误合断路器可采用提示性的措施外,其他四防应采用强制性闭锁,从而减少不利因素对它造成的干扰。

Guiyang switchgear reminded to set the lock device since small switch cabinet, it should at least have five functions, in addition to prevent error, error closing circuit breaker can adopt prompt measures, the other four case should adopt mandatory locking, thereby reducing the adverse factors caused by interference on it.


同时还要保证采用规定的程序来操作小型开关柜闭锁装置,一方面是为了确保人员在操作开关柜时的安全,同时也是为了保证开关柜不受损坏。一般情况下,尽可能采用机械闭锁,这种方式比较简单、可靠、操作维护方便。

At the same time, it is also necessary to ensure the use of the prescribed procedures to operate the locking device of the small switch cabinet, on the one hand, to ensure the safety of the staff while operating the switchgear, and also to ensure that the switchgear is not damaged. In general, mechanical locking is used as much as possible. This method is simple, reliable, and easy to operate and maintain.


如果小型开关柜使用的就是机械闭锁,那么机械程序锁应符合相关的金属要求,比如开启灵活、可靠、钥匙插、拔自如,无卡涩现象;进行非程序操作时,开关柜不得操作等。

If a small switchgear is mechanical lockout, mechanical program locks should conform to the relevant metal requirements, such as opening flexible, reliable, key inserting, pulling freely, and no card jam. During non program operation, switchgear shall not operate.


除了传统的机械闭锁之外,小型开关柜也可以采用电气闭锁技术,但要求闭锁元件的电源应与继电保护回路分开;而且闭锁回路和接点应满足闭锁要求;布线应合理等等。

In addition to traditional mechanical lockout, small switchgear can also adopt electric locking technology, but the power supply of blocking elements should be separated from relay protection circuit. Besides, locking circuit and contact should meet the requirements of locking, wiring should be reasonable and so on.
