配电变压器桩头过热故障的处理

Research on Treatment of Overheat Fault at the Distribution Transformer Terminals

公用变压器的桩头过热引起的故障停电是公变停电的一个重要原因。文章通过分析以及现场实际调查,发现了引发配电变压器桩头过热的原因,并提出了针对性的改进措施,特别是通过对线夹选材和引线捆扎方法的改进,有效减小了接触电阻,减轻了电流的热效应。

The overheat terminal of public transformer is an important cause to lead outage. Through analysis and inspection at site, the cause of overheat terminal was found out and the improving measure was proposed, especially how to choose the clamp material and make the wire bundle, which effectively reduces the contact resistance.
