漏电断路器发生故障如何去解决?

来源:http://www.jntongyu.com/ 日期:2021-07-13 发布人:admin

我们有些对断路器不是很了解的客户会有这种迷茫,自己明明已经安装了漏电断路器,开关也是好的,但是在发生短路时电器设备还是会被烧毁,下面我们就来为大家解决一下。

Some of our customers who don't know much about circuit breakers will have this kind of confusion. They have installed leakage circuit breakers, and the switches are good, but in the event of a short circuit, the electrical equipment will still be burned. Let's solve it for you.
一般情况而言,漏电断路器又名漏电开关,它可以分为两大类,一类是漏电保护功能和过电流保护功能相结合的产品,而另一类则是仅有漏电保护功能的产品。这两种在实际中都有其特定的用途。
Generally speaking, the residual current circuit breaker, also known as leakage switch, can be divided into two categories, one is the combination of leakage protection function and over-current protection function, and the other is the product with only leakage protection function. Both of them have specific uses in practice.
前者在其设计制造过程中考虑的较为全 面,它考虑了短路保护,具有高分断能力,能够分断短路电流,而且在线路中发生漏电的情况下,也能够正常的切断电源从而起到保护的作用。
The former is more comprehensive in its design and manufacturing process, it considers the short-circuit protection, has high breaking capacity, can break the short-circuit current, and in the case of leakage in the line, it can also cut off the power supply normally, so as to play the role of protection.
塑壳熔断器它适用于作支路的保护开关。而后者则只能在线路产生漏电时切断其正常的负荷电流,其本身并没有过电流保护功能,因此也就通常用来与与熔断器配合使用,用熔断器来切断短路电流。
Moulded case fuse is suitable for protection switch of branch circuit. The latter can only cut off the normal load current when the line has leakage, and it has no over-current protection function, so it is usually used with fuse to cut off the short-circuit current.
倘若我们使用的断路器是后者,且没有加装熔断器,那么在线路发生短路时的漏电开关就不能分断,电器设备也就会被烧毁。所以一般情况下建议的选择是,要么是前一种漏电断路器,要么就选择后者,外加熔断器。
If the circuit breaker we use is the latter, and there is no fuse, then the leakage switch can not be disconnected when the line is short circuited, and the electrical equipment will be burned. Therefore, under normal circumstances, the choice recommended by experts is either the former type of residual current circuit breaker or the latter, plus fuse.
