施工现场配电箱漏电保护报警控制电路的应用

Application of Electric Leakage Protection Alarm Control Circuit for the Power Distribution Box

由于施工现场的配电箱长期暴露在外界环境中,导致其密封性能降低,引发漏电、触电事故发生。为了提高安全用电水平,除在三级配电箱配备漏电保护器外,还应配备相应的漏电报警装置。当发生了漏电、触电事故时,能够及时将故障排除,避免引起设备损坏、火灾、甚至发生人员伤亡的严重后果。

Because of the long- term exposure to the external environment,the distribution box has caused the decrease of the sealing performance,and lead to the electric leakage and shock accident. Besides the earth leakage protection,alarm devices should also be equipped,in order to improve the safety. When the leakage comes,the troubles can be eliminated immediately.
