摘　　要：矿用本安电源是煤矿井下供电设备中的重要组成部分,矿用本安电源不仅包括主电路、保护电路,同时还包括备用电源以及防爆外壳,其中保护电路也是其核心部分。通过在矿用本安电源保护电路设计中加入MAX4080SASA的电流检测芯片和LM339比较器设计的新型保护电路,针对本安电源中的保护电路进行优化设计,以期进一步提高本安电源的质量和安全性。Mine intrinsically safe power supply is an important part of power supply equipment in coal mine. Mine intrinsically safe power not only includes the main circuit, protection circuit, but also has a standby power supply and an explosion-proof enclosure. The protection circuit is also the core part. By adding MAX4080SASA current detecting chip in protection circuit design and LM339 comparator design model in mine intrinsic safe power, protection circuit has been optimized designed, which further improve the quality and safety of intrinsically safe power supply.
