摘要(Abstract):
随着状态检修工作的大力推进,带电监测诊断系统的重要性不断显现。介绍了温州电力局科技项目——变压器放电性故障综合带电监测与诊断技术系统。该系统能够在电磁干扰较强的变电站环境下稳定运行,可全天候连续带电监测电力设备的故障放电信号。在运行中及时发现多次设备故障隐患,为保障电力系统安全运行做出了贡献。
This paper introduces an on-line partial discharge (PD) monitoring and diagnosing system. Partial discharge (PD) is important factor for judging the insulation condition of power equipments. On-line monitoring system can inspect power equipments′ traits continuously and predict the latent faults in time by observing the change of traits. Now the system has been applied successfully in some substation,and the applying results are satisfying.
