Description

一种含有过压保护的漏电保护开关
技术领域
本实用新型涉及电器开关，尤其涉及一种漏电保护开关。 
背景技术
对于众多的低压用电设备，通常使用三相四线制供电，电压分为：380V和220V两个等级。时常会发生线路接错，零线接成相线使电压升高，还有中心线接线不紧断线使零线电位漂移电压升高，常使贵重的电器设备或家用电气烧坏的情况。给供电方和用户带来不小的损失。为解决该问题，通常采用过电压继电器，当电压一高就断电，但对于漏电保护开关而言，成本较高不适用。 
发明内容
本实用新型旨在解决上述缺陷，提供一含有过压保护的漏电保护开关。本实用新型简采用单过电压保护元件，便能更好的保护电气设备的使用安全，即经济又实用。 
为解决上述问题，一种含有过压保护的漏电保护开关，所述漏电保护开关接在相线和零线之间，它还包括一个由限流电阻和过电压保护按钮组成的过压保护电路，该外接过压保护电路和所述漏电保护开关并联。 
本实用新型是在漏电开关的基础上，根据漏电原理和过电压的特性原理，漏电开关与附加的过压保护设备配合使用，起到过电压保护的目的。本实用新型只要增加一个过电压保护元件，元件并联到漏电开关外部的上下端即可。根据使用电压，设置过电压保护值。 
附图说明
下面结合附图对本实用新型作进一步的说明： 
图1为本实用新型示意图。
具体实施方式
如图1所示：一种含有过压保护的漏电保护开关，所述漏电保护开关1接在相线和零线之间，它还包括一个并联到漏电开关外部的上下端的、由限流电阻2和过压保护按钮3组成的外接过压保护电路。根据使用电压，设置过电压保护值。
