主变压器身绝缘老化的一种定量检测方法探讨

A Quantitative Detection Method Discussion of the Main Transformer Insulation Aging

提出对SS系列机车主变压器线圈的电气绝缘结构进行高压直流泄漏电流试验 ,对线圈绝缘老化程度和绝缘状态进行定量检测和技术性诊断是解决主变压器检修中绝缘老化问题的行之有效的方法 ,从而在运行中避免事故隐患。同时在主变压器身运行到极限寿命期内 ,建立绝缘状态技术档案 。

Suggest an effective method to solve the insulator aging problem in the main transformer examine and repair,The method includes:high voltage detect current leak current examination to the electric insulation structure of SS series locomotive main transformer,quantitative detection and technical diagnosis to the winding insulation aging degree and insulation status,so as to avoid the hidden trouble of accident.At the same time,when the main transformer runs to the terminal life period,establish insulation status technical document,in order to provide the measurement base line for life cycle and obsolescence problem.
