摘　　要：为了提高煤矿的安全和自动化程度,煤矿电气设备多会采用矿井隔爆和固有安全组合开关。在分析煤矿地下工作面的供电特点基础上,采用本质安全型电气元件,设计了矿井隔爆和固有安全组合开关的保护电路,重点对漏电保护、短路保护等硬件保护电路等方面进行了分析设计,通过模拟故障验证,该系统能有效地保护电路系统,保证煤矿生产的安全。In order to improve the safety and automation degree of coal mine,the combination switch of mine flameproof and inherent safety is often used in coal mine electrical equipment.On the basis of analyzing the power supply characteristics of underground working face in coal mine,the protection circuit of mine flameproof and intrinsically safe combination switch is designed by using the intrinsically safe electrical components,and the hardware protection circuits such as leakage protection and short circuit protection are mainly designed.Through the simulation fault verification,it shows that the system can effectively protect the circuit system and ensure the safety of coal mine production.
