微机变压器差动保护及其调试方法

Microcomputer Transformer Differential Protection and Debugging Methods

通过对变压器差动保护原理分析,重点讲述了差动保护不平衡电流产生原因和微机保护处理方法,以及不同保护装置制造厂家在保护软件程序编制原理上的区别,介绍了利用试验仪手动和自动菜单进行变压器差动保护调试的方法和注意事项,提出了加电压模拟差动保护的设想,供同行的工作者参考。

Through the analysis of transformer differential protection principlsd, the paper mainly tells the unbalance current differential protection reasons and microcomputer protection treatment methods, as well as various protection device manufacturer in protection software programming principle differences, and introduces the use of test instruments manual and automatic menu for transformer differential protection debugging methods and attentions, and puts forward the idea of voltage analog differential protection, offering references for the colleague.
