电力变压器运行维护及故障处理的分析

Analysis of Operation,Maintenance and Fault Handling of Power Transformers

为提高变压器的运行效率,减少故障发生并确保电网的连续供电能力,采用定期监测、预防性维护和快速响应的故障处理策略,安装传感器和在线监测系统,实时监控变压器的运行状态。结合历史数据和运行经验,制定针对性的维护计划,并采用故障诊断技术准确计算故障位置,实现常见短路故障和接地故障的精确定位。在故障处理方面,该策略能够快速准确地诊断出故障原因并及时修复,缩短停电时间,有效提升变压器的运行稳定性,大幅降低故障率。

In order to improve the operation efficiency of transformer,reduce the occurrence of faults and ensure the continuous power supply capacity of power grid,the fault handling strategy of regular monitoring,preventive maintenance and quick response is adopted,and sensors and online monitoring system are installed to monitor the operation state of transformer in real time.Combined with historical data and operation experience,the targeted maintenance plan is made,and the fault location is accurately calculated by fault diagnosis technology,so as to realize the accurate location of common short-circuit faults and grounding faults.In terms of fault handling,this strategy can quickly and accurately diagnose the cause of the fault and repair it in time,shorten the power outage time,effectively improve the operation stability of the transformer and greatly reduce the failure rate.
