摘要
讨论了检测盘形悬式瓷绝缘子的火花间隙法、电压分布法、测量绝缘电阻法、航测法和地面初判法。认为采用火花间隙法和电压分布法检测绝缘子,有漏检、误判等现象;采用在线绝缘电阻法进行测试,可靠性较高。同时指出,航测法和地面初判法是今后在线检测的发展方向。
The methods of ceramic cap and pin insulator monitoring such as spark gap detecting voltage distribution testing, insulation resistance measurement, aerosurveying and ground surveying were reviewed. It is considered that missing or mistaken judgement can occure using spark gap detecting and voltage distribution testing method and measurement of higher accuracy can be achieved using on-line insulation resistance measurement method. The on line monitoring tends to use aerosurveying and ground-surveying method in future.
