Points for Attention in Installation and Application of Residual Current Circuit Breakers

剩余电流断路器在安装和使用中应注意的事项

Aim at the problem of the pressure small, easily test error of adoption shunting line test residual press, develop a new track circuit shunt-residual press fix tester.

针对目前采用分路线测试残压产生压力小，易造成测试误差的问题，研制开发了一种新型轨道电路分路残压定压测试器。

Furthermore, all kinds of electric residual current operated device have been using the traditional analog integrated circuit to achieve the single protect function.

另外，各类电子式剩余电流保护器一直沿用传统的模拟集成电路器件来实现单一的漏电保护功能。
