河南电网500 kV并联电抗器运行状况分析

Analysis of the 500 kV Shunt Reactors Operation Condition in Henan Power Grid

500 kV并联电抗器是电力系统的主要设备之一,它的安全运行具有重要意义。目前500 kV电抗器运行状态的监测手段主要包括振动测量、噪声测量、红外测温和绝缘油色谱试验等。介绍了利用上述方法对河南电网500 kV并联电抗器进行运行状况分析的情况,认为个别电抗器存在过热、振动偏大等缺陷,要加强对这些设备的监视;并建议尽快对郑州站白郑线电抗器和白河站樊白II回线电抗器加装色谱在线监测装置,实时跟踪电抗器内缺陷发展的情况,避免出现大的运行事故;建议对郑州站白郑线电抗器的套管下部油箱位置加装支撑装置,减少油箱突出位置的受力,减少振动,防止该处出现故障。

500 kV Shunt reactor, as one of the primary equipments of power system, its＇ safety operation is of importance. The mainly measures used for 500 kV reactor condition-measuring includes vibrating measurement, noise measurement on site, temperature measurement based on infrared technology and the insulating oil chromatogram analysis for measuring insulating condition etc. In this paper, the analysis of 500 kV shunt reactors＇ operation condition in Henan power grid, which has taken use of the above measures, is introduced and stated. It is meaningful and valuable for how to strengthen the monitoring of reactor during running process to ensure the reactors operation safety.
