电涌保护器与漏电保护器配合使用

With the Use of Surge Protection Device and Residual Current Operated Protective Device

低压配电系统中,电涌保护器与漏电保护器配合使用,当雷雨天气来临时,许多带漏电保护器功能的断路器出现跳闸现象。本文对电涌保护器与漏电保护器原理、保护功能、使用中存在问题,以及电涌引起跳闸问题作了分析,提出了电涌保护器与漏电保护器配合使用的建议方案。

In low-voltage distribution system, a surge protector is used in conjunction with a leakage protector. When thunderstorm is coming, many circuit breakers with a leakage protector will trip out. This paper analyzes the principles and functions of surge protector and leakage protector, the problems when they are used as well as how surge causes tripping. What＇ s more, solutions to the cooperation of surge protector and leakage protector.
