变电站在线监测系统在三水电网中的运用

Application of on-line Monitoring System for Substation Used in Sanshui Grid

广东三水110 kV芦苞变电站安装了一套高压设备在线监测系统,对变电站内的变压器、绝缘子、避雷器和SF6断路器等进行在线监测。通过近4年的运行,该系统在线测量的参数准确、稳定可靠。应用这套系统可以实时掌握变电站高压设备的绝缘及健康状态,分析设备状态发展趋势。这对提高设备的运行维护水平,及时发现事故隐患,减少停电事故有着积极的意义。

Application of on - line monitoring system fur power substation used in 110 kV Lubao substation in SanShui grid is introducet. The main equipment, such as transformer, insulator, lightning arrestor, SF6 cireuit breaker, are monitored on -line by the system. After operation for 4 yeats, the conclusion is that the parameters detected by the system are accurate and the system running is stable. With the system the insulation and health conditions of the HV equipment in the substation can be understood timely and development trend of the equipment can he analyzed, which is of importance in improving the operation and maintenance level, timely finding out hidden defects and decreasing the failure of blackout.
