摘　　要：通过分析由于内部不清洁原因引起GIS内部放电击穿而导致母线短路的故障案例,经过SF6分解产物测试和解体检查,对此故障进行了诊断,确认了放电故障由SF6气体间隙放电引起,并分析了放电通道和放电原因。A fault case of internal discharge in GIS and leading to a short circuit due to unclean internal environment was analyzed. The fault was diagnosed through testing the SF6 decomposition products and disassembly part and it was concluded that the SF6 gas gap discharge causes the result. The discharge channel and reason were then analyzed.
