GIS设备常见发热缺陷的分析及其预防措施

Analysis of Common Heat Defects of GIS Equipment and Its Preventive Measures

针对GIS设备发热缺陷屡见不鲜的问题,分析了GIS母线外壳波纹管发热和GIS出线分支母线外壳接地汇流排发热这两个典型案例,并提出了相应的预防措施。分析认为,GIS外壳发热缺陷会导致绝缘老化、密封部件受损,甚至引起事故,设备管理和运维部门均应给予足够的重视。

For GIS equipment heat defects are common,two typical cases of GIS bus shell bellows heat and GIS outlet branch bus shell grounding busbar heat are analyzed and corresponding preventive measures are proposed.The analysis concluded that GIS shell heating defects can lead to insulation aging,damage to sealing components,and even cause accidents,and equipment management and operation and maintenance departments should pay sufficient attention to them.
