摘要
传统的定期检修已不能满足高压输变电设备安全运行的要求,以状态检修代替定期检修已成为电力系统设备检修的必然趋势。实时的绝缘监测及诊断技术是状态维修的基础。电容型设备在变电站中具有重要地位,因而对其绝缘状况进行在线监测具有重要意义。本文介绍了电容型设备在线监测的具体内容(如在线监测信号的提取和介损数字化测量等),电容型设备在线监测和诊断技术的研究现状与应用状况,并就其存在的问题和对今后的技术发展提出了建议。
With rapid development of power system, the traditional periodical maintenance can not meet the need of secure operation of high voltage equipments for power transmission and transformation. Therefore, it is an inexorable trend to replace the traditional periodical maintenance with condition based maintenance step by step and the real-time insulation monitoring and diagnosis is the basis of condition based maintenance. Capacitive equipment possesses important position in substation, so the real-time monitoring of its insulation situation is very important. The contents of on-line monitoring of capacitive equipment are described. The present situation of the research on the on-line monitoring and diagnosis and its applications are expounded. Some suggestions for existing problems in this field and its further development are proposed.
