摘要

介绍了小浪底电厂SLZ8-315/10.5型干式变铁心夹件连接螺杆的发热问题

分析出零序磁通和漏磁通为发热的主要原因

并设计了消除发热的几种方案

最后通过实验对比得到最佳方案。结果表明

连接螺杆的发热现象得到消除

并使变压器的损耗得到有效降低。

Abstract

The calorific problem of the connection screw rod on the core fastener of dry-type transformer SLZ8-315/10.5 used in Xiaolangdi Power plant was discussed.It was found that the main cause of the calorific problem rooted in zero-sequence flux and stray flux.Several programs to deal with the problem were designed and the best one was screened out via experiments.With the present program the calorific problem of the connection screw rod was solved

and the power loss of transformer was effectively reduced.
