浅析电气设备接头发热的原因及消除措施

Analysis on the Causes of Heating in the Joints of Electrical Equipment and the Measures to Eliminate Them

随着电网集控功能的发展,在66kV变电站运行方面,已经实现远方监控,变电站的建设也越来越集中化、规模小型化、设备集约化的方面发展。同时,地方经济也在飞速发展,用电负荷在成几何方式增长,电力系统中的电气设备在运行中,设备接头发热问题也成为了设备安全运行工作的一项重要内容,对设备接头的监控也显得尤其重要,设备接头的安全运行与否严重影响了电网的供电可靠性。本文对造成设备接头发热问题的原因进行了分析,并提出相应的措施。

Along with the development of centralized control function of power network,remote monitoring has been realized in the operation of66kV substation,and the construction of substation is becoming more and more centralized and the scale is miniaturized.At the same time,the local economy is developing at full speed,the electric load is increasing in geometric way,and the electric equipment in the power system is in operation.The heating problem of the equipment joint has also become an important part of the safe operation of the equipment,and the monitoring of the equipment joint is especially important.The reliability of power supply is seriously affected by the safe operation of the equipment connection.The causes of the heating problem of the equipment joint are discussed in this paper.An analysis is made and the corresponding treatment measures are put forward.
