缩短牵引变压器试验时间策略的研究

Research on Strategies for Shortening the Test Time of Traction Transformers

牵引变压器是牵引供电系统的“心脏”其工作性功能的好坏直接关系到整个牵引供电工况。按照牵引变压器试验规程要求开展变压器周期试验,不同试验项目需要使用不同规格的测试线,现场测试线多,难于整理,接线复杂,影响试验效率。本文通过调查研究变压器试验过程各环节耗时情况,查找变压器试验时间长的问题根源,并给出了提高变压器试验效率的方法以及相应的对策。

The traction transformer is the“heart”of the traction power supply system,and its working function directly affects the entire traction power supply working condition.According to the requirements of the traction transformer test regulations,transformer cycle tests are carried out.Different test items require the use of different specifications of test lines.There are many on-site test lines,which are difficult to organize and have complex wiring,affecting the efficiency of the tests.This article investigates and studies the time consumption of each loop in the transformer testing process,identifies the root cause of the problem of long transformer testing time,and provides methods and corresponding countermeasures to improve the efficiency of transformer testing.
