摘要
介绍了冀北电网中应用的油中溶解气体在线监测、局部放电在线监测、铁心接地电流在线监测、电容型设备介损及电容量在线监测、避雷器泄漏电流在线监测等电力设备在线监测技术。给出了电力变压器磁屏蔽破损、电容式电压互感器缺陷等实际应用实例,对在线监测工作开展情况进行了简要总结,并对后续工作提出了一些建议。
On-line monitoring technology commonly applied in Jibei power grid is introduced, including oil dissolved gas,partial discharge, earth current of iron core, capacitive equipments and metal oxide arrester on-line monitoring technology. Two application cases related to the defect of magnetic shield insulation in a power transformer and a fault in CVT given in this paper are given, with experiences on the monitoring and operation of such tests summarized briefly, and some suggestions on the implementation of on-line monitoring technology are proposed.
