变电站高压电气设备状态检修的现状及其发展

变电站高压电气设备越来越趋向于在不可能长时间停役检查和检修的情况下运行，因此必须适时地开展状态检修。这就有必要对运行中的变电站设备进行监视和诊断，以便能检测到异常情况的征兆或使用寿命终结的迹象。文中简要综述了电气设备状态检修的现状及其发展；着重讨论了作为状态检修的基础的在线监测和故障诊断的方法；提出了对状态检修内涵的观点。认为一个安全、可靠、实时的在线监测系统无疑将为变电站高压电气设备的状态检修提供更为有利的条件。

CURRENT STATUS AND DEVELOPMENT OF CONDITION-BASED MAINTENANCE OF HIGH-VOLTAGE ELECTRIC POWER EQUIPMENT IN SUBSTATION

It is becoming impossible that the high--voltage electric power equipment lays off in long--playing case to be examinedand repaired. The condition--based maintenance must be developed in good time. In order to detect abnormal symptom orterminative evidence of the working--life, it is necessary to monitor and diagnose on-line about high-voltage electric powerequipment in substation. The current status and development of condition--based maintenance (CBM) of electric powerequipment are summarized. The method of insulative on--line monitoring and failure diagnosis is emphatically discussed, whichis the basis of CBM. Furthermore, the viewpoint about the connotation of CBM is put forward. Clearly, one safe, credibleand real-time on-line monitoring system will provide more advantageous condition for CBM of high-voltage electric powerequipment in substation.
