摘　　要：阐述了二总线在井下漏电保护装置中的应用,通过总保护的微机对井下绝缘电阻的实时监控及总保护和分支出口保护之间的总线通信,快速判断出故障线路并及时隔离故障,从而全面提高了井下工作的安全。The application of'two buses'in creepage protection is introduced.Using the commu-nication between whole protection and branch outlet protection,the insulation resistance is real-time monitored by the microcomputer of the whole protection.The faulty line can be thus quickly selec-ted out and then isolated to wholly improve the safe work conditions under well.

关 键 词：漏电保护 二总线 零序电流
