摘　　要：通过对金属封闭式开关柜结构及绝缘故障类型的分析,认为测量开关柜内部局部放电和过热可对开关柜绝缘故障进行预警,并提出在开关柜顶部装设超声局放检测装置,在内壁装设光纤测温装置,可实现开关柜绝缘在线检测。In this paper, the structure of the enclosed metal switchgear and the types of the insulation fault is analyzed. By measuring the internal partial discharge switchgear and switchgear overheating, the insulation failure can be early warned. By putting the ultra sonic PD detector device at the top of the switchgear and by installing the temperature measuring device on the inside walls, the insula tion live testing can be achieved.
