摘要
电压互感器是铁路电力系统中的重要设备,用于高压侧的测量、隔离一次设备、监测高压侧绝缘等方面。文章针对铁路电力系统中由于铁磁谐振而导致电压互感器发生故障,进而影响铁路供电系统安全的情况,分析了铁磁谐振发生的影响因素,并提出对应的措施。
Potential transformer is an important device in the railway power system, which is used in the measurement of high voltage side, isolation of primary equipment, monitoring of high voltage side insulation and so on. In view of the fault of potential transformer caused by ferro-resonance in railway power system, which affects the safety of railway power supply system. This paper analyses the influencing factors of ferro-resonance and puts forward corresponding measures.
