影响介损在线检测结果的因素分析及诊断策略

Analysis and diagnosis about factors to influence on-line measuring result of dielectric loss

当前电容型设备介损在线检测装置的现场运行效果并不理想,其反映出来的技术问题主要是介损测量结果存在较大的分散性,难以据此对绝缘状态作出准确的在线诊断.通过对影响介损在线检测结果的各种因素的分析,针对实际应用中存在的问题,讨论了在线检测数据处理方法及诊断策略.

Operation effect of actual dielectric loss on- line measuring device using for capacitive- type device lsn t perfect, main technology problem reflected by it is dispersiveness of measure result, so it is difficult to diagnose insulation situation correctly according to the measure result. By analyzing all kinds of factors to influence on- line measuring result of dielectric loss, aiming at the problems existing in application, discusses the treatment method and diagnosis strategy of on- line measuring data.
