摘要

本文分析了35kv变电站干式变压器在接地故障情况下有载分接开关损坏的原因。为了分析这些过程，在众所周知的变压器瞬态建模技术[1,2]的基础上，补充了从静电场图中确定变压器的匝间和绕组间电容。

Investigation of causes of dry-type transformer on-load tap-changer insulation

The article represents the analysis of the causes of damage on the on-load tap-changer of a dry-type transformer installed at a 35 kV substation under ground fault in a network with isolated neutral. In order to analyze these processes, the well-known technique of modeling transients in a transformer [1, 2] is supplemented with account of the interturn and interwinding capacitances of the transformer determined from the picture of the electrostatic field.
