摘要
针对电力机车/动车组断电通过关节式电分相装置时仍产生过电压,分析了击穿放电间隙造成变电所跳闸事件的故障机理。介绍通过暂态求解得出过电压幅值的计算公式,确定其性质为合闸过电压和谐振过电压。
Analyses the mechanism of over voltage, when the electric locomotive is passing the articulated phase insulator. Through transient solution, formulas for calculating the voltage amplitude and the conclusion that its nature is closing over-voltage and resonant over-voltage are given.
