矿用配电装置枪栓式两防锁的设计

Design of Gun Bolt Type Two-Proof Lock for Mining Distribution Units

针对目前煤矿井下高压配电装置、低压馈电开关等电气产品的现有使用的两防锁装置存在的问题进行分析,设计一种枪栓式两防锁,有效地“防止擅自送电、防止擅自开盖操作”,实现矿用电气设备的本质安全操作。

In view of the problems of the existing two-proof locking devices used in electrical products such as high-voltage distribution devices and low-voltage feeder switches in underground coal mines,a gun-bolt type two-proof lock is designed to effectively"prevent unauthorized power supply and unauthorized cover opening"and realize the intrinsically safe operation of mining electrical equipment.
