变压器振荡型冲击电压下的局部放电测量
Measurement of partial discharge under oscillatory impulse voltage for transformer
摘要
Abstract
In order to improve the ability of finding hidden insulation defect of oil-immersed transformer,researches the discharge property of typical oiled paper insulation defect under oscillatory impulse voltage,masters the characteristc and law of partial discharge under oscillatory impulse voltage,puts forward the measuring method of partial discharge when making oscillatory impulse voltage test,develops transformer partial discharge detection system based on oscillatory impulse voltage,solves problem of complete measurement for partial discharge pulse voltage,realizes preliminary the distinguishment of partial discharge and diagnosis of insulation state,the site application result shows that the system detecting insulation defect of oil-immersed transformer is effective.关键词
