摘要
随着电力系统和电力市场的发展,变电站高压电气设备越来越趋向于非长时间停役检查和检修运行,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,以便能检测到异常的征兆或使用寿命终结的迹象。简要综述了电气设备状态检修技术;着重讨论了在线监测和故障诊断的方法;并就数字化变电站对状态检修的影响进行了探讨。同时对这个领域中存在的问题和今后技术的发展提出了建议。
With development of power system and power market, high-voltage power equipment of transformer substation more and more tends to operate without long time service-stop inspection and maintenance. Thus the conditionbased maintenance must he developed in time and it is necessary of monitoring and diagnosing equipments in transformer substation to detect abnormal situations or end characteristics of service life. A summary of condition-based maintenance technology for power equipment was given in this paper. And on-line monitoring and diagnosis was emphatically discussed . Effluence of digital substation on condition-based maintenance was discussed too. Meanwhile, problems of this domain and development in the future were brought forward.
