摘　　要：煤矿井下6kV电网防爆开关是矿井供电系统中的关键设备,开关的性能直接影响矿井供电的可靠性、安全性和连续性。运用单片机技术和现场总线技术对开关的保护系统进行改进,不但使系统的可靠性有所增强,而且更易于用户操作和维护,同时也满足了矿井自动化系统升级的需要。The high voltage flameproof switchgear is a key apparatus for 6kV-power supply system in underground mines. The switchgear＇ s performance impairs the reliability, safety and continuity of underground power distribution system. The protection sysytem is improved with single chip computer and field bus technology. Not only the stability is increaced but also the use and mantenace is more simple. It meets the upgrade of automantic control system in underground mines.
