小容量高电压电力变压器介损的探讨

Discussion on Dielectric Loss of Small HV Power Transformer

本文中笔者对小容量高电压变压器的介质损耗因数进行了分析,并对高压绕组、低压绕组、变压器油和电容式套管介质损耗因数进行了测量和计算,找出了其超标的原因并进行了改进。

The dielectric loss tangent of small HV transformer is analyzed by the authors in this paper. The dielectric loss tangents of HV winding, LV winding, transformer oil and capacitor bushing are tested and calculated. The overproof reasons are found. The improvement is presented.
