一、电煤钻综合保护装置的性能测试电路电煤钻综合保护装置(以下简称“综保装置”)普遍用于煤矿井下采煤工作面,作为127V 手持式电钻的漏电、短路保护。由于采煤工作面条件恶劣,电钻电缆常因砸、压、埋而引起短路、漏电的故障,如综保装置的保护性能不可靠,就可能因短路、漏电故障而引起瓦斯、煤尘爆炸事故,危及职工 First, the electric coal drill integrated protection device performance testing circuit Electric coal drill comprehensive protection device (hereinafter referred to as “comprehensive security device”) is generally used for coal mining face, as 127V handheld electric drill leakage, short circuit protection. Due to harsh coal mining conditions, drill cable often due to smashing, pressure, buried caused by short circuit, leakage fault, such as comprehensive protection device performance is not reliable, it may be due to short circuit, leakage fault caused by gas, coal dust explosion accident , Endanger the workers
