一起漏电开关误动作的分析

The Electric Leakage Switch Analysis of the Wrong Misoperation

漏电开关用于直接接触触电的人身安全保护,由于其核心部件是一块电子线路板,因此外界的某些干扰可能造成其动作。而部分国产质量较差的电子整流器型荧光灯由于对外干扰抑制达不到规定值,其过电压和谐波值都较大。本文主要从一个工程实例,分析出过电压和谐波可以造成电子式漏电断路器动作。

The electric leakage switch useds for the life safety protection that direct contact get an electric shock, because its core parts is a piece of electronics circuit plank,so the external world of some interference may result in it act。But the worse electronics of part of domestic quantities commutates a fluorescent lamp of machine because of outward the interference repress to can not reach the provision value,it conducts electricity to press to harmonize wave the values all compare greatly。 This text mainly from an example with solid engineering, analyze to conduct electricity to press the harmonious wave and can result in the electronics type electric leakage chopper act。
