配电变压器高压侧缺相过压分析

针对在配电变压器高压侧缺相时引发的过电压损害，分析了造成这类过电压的原因，并提出了针对性解决办法。

一起配电变压器损坏故障分析

针对坑内变压器故障后同时存在一相高压跌落熔丝熔断、变压器散热片出现破口和台区两相供电电压偏低的故障,逐一分析故障原因,由于变压器长期过负荷运行,低压出线与变压器散热片距离太近,引起绝缘损坏,出现间歇性电弧放电,造成散热片出现破口,从低压线与散热片之间的空气间隙完全被击穿,演变成单相接地短路,变压器缺相运行,文章在工艺上和运行管控上提出建议。

电力监控在邵永高速公路的应用

由于湖南邵永高速公路有限公司营运管理模式是采用集中监控,大站带小站集中居住的管理模式,即小站时无水电工及维护人员值守如果要及时了解发电机的运行状况及参数就显得鞭长莫及。而电力监控可以很好地解决该类问题,本文浅谈了电力监控在邵永高速公路的应用。

A new measuring technique in detecting of high voltage three phase induction motor for single phasing

Open phase in three phase induction motors is a common fault that can occur as a result of a fuse blowing or a pro- tective device failing on one phase of the motor. This paper introduces a new method,which is based on the transient mea- surement and can distinguish the fault of one phase connecting ground. The method has been proved to be in correspondence with the simulation results by Matlab and LabVIEW in practice, The method has merits of simplicity, accuracy and ease of USe.
