摘 要：氣體絕緣開(kāi)關(guān)設(shè)備 (GIS) 受制造技術(shù)、裝配工藝、運(yùn)行環(huán)境等因素影響，運(yùn)行中可能會(huì)出現(xiàn)六氟化硫 (SF6) 氣體泄漏、局部放電等故障。介紹了某 220 kV 氣體絕緣設(shè)備伸縮節(jié)氣室漏氣放電， 220 kV 母差保護(hù)動(dòng)作跳閘事故，解體故障氣室，從環(huán)境、受力、導(dǎo)體等方面進(jìn)行了故障分析，并給出了整改措施，對(duì) GIS 設(shè)備的運(yùn)行維護(hù)具有一定的借鑒意義。
關(guān)鍵詞：氣體絕緣開(kāi)關(guān)設(shè)備 (GIS) ；伸縮節(jié)；SF6 泄漏；檢查分析

Abstract: Gas-insulated switchgear (GIS) might have SF6 gas leakage, partial discharge, and other faults during operation affected by factors such as manufacturing technology, assembly process, operating environment, etc.This paper introduced the leakage discharge phenomenon of 220 kV gas insulation equipment telescopic throttle chamber, the tripping accident of 220 kV bus differential protection action,the disassembly of the failure air chamber. The study analyzes the failure from different perspectives, such as environment, stress, conductor,etc., and provides the rectification measures, which have certain reference significance for the operation and maintenance of GIS equipment.
Key words: gas-insulated switchgear (GIS); expansion joint; SF6 leakage; check and analysis
