摘要

通过对大量现场测试数据的比较分析表明

现场低电压下测得的环氧树脂浸纸电容式油/SF6套管的介损并不能完全反映套管介损的真实值。通过改变试验的接线方式、停电前的励磁方式和空载投切相角的研究和试验

有针对性地提出了防范措施。

Abstract

Analysis of a gerat am ount of field-test results show that the dielectric loss of epoxy resin oil/SF 6 bushing obtained under low voltage is not able to repersent the real conditi on of the bushing.Through changing the connection for test

changing the excitat ion mode and the phase angel before de-energizing the transformer

proposals to p revent inaccurate measurement are given.
