1、 前言

漏电断路器(residual current circuit-breaker): 电路中漏电电流超过预定值时能自动动作的开关。常用的漏电断路器分为电压型和电流型两类,而电流型又分为电磁型和电子型两种。漏电断路器用于防止人身触电,应根据直接接触和间接接触两种触电防护的不同要求来选择。

智能漏电断路器模块解决方案

电压型漏电断路器用于变压器中性点不接地的低压电网。其特点是当人身触电时,零线对地出现一个比较高的电压,引起继电器动作,电源开关跳闸。电流型漏电断路器主要用于变压器中性点接地的低压配电系统。其特点是当人身触电时,由零序电流互感器检测出一个漏电电流,使继电器动作,电源开关断开。
