变电设备在线监测与故障诊断技术

Online monitoring and fault diagnosis technology of electric power equipment

检修是保证电气设备正常运行的必要手段,在电力系统中推行状态检修是电气设备检修制度发展的必然选择。介绍了电力系统状态检修技术的发展与现状,给出了变压器、断路器、避雷器等变电设备在线监测的基本方法与故障诊断的工作原理,阐述了基于在线监测与故障诊断的状态检修技术,并指出了实施该技术目前存在的问题和今后发展的方向。

For power equipment, condition-based maintenance is bound to be the principle of equipment maintenance, which means much to the healthy of power system. The paper introduced the development and current situation of condition-based maintenance in electric system, and fundamental methods of on-line monitoring and operating principles of fault diagnosis with transformer,breaker,arrester have been given,the condition-based maintenance on the basis of on-line monitoring and fault diagnosis has been expounded. In the end, problems to put the technology into practice at present and the direction to develop in the future were pointed out.
