摘要
分析接触网"V"形天窗停电作业时静电感应和电磁感应2种感应电压形成机理,通过计算静电感应电压、直接供电和直供加回流供电方式下电磁感应电压,得出感应电压大于安全电压的结论,据此提出相应的预防措施,为牵引供电系统安全运行和维护提供借鉴。
Analyzes the mechanism of formation of static inductive voltage and two types of electromagnetic inductive voltage during OCS ＂V＂ type skylight power off operation, obtains the conclusion that the inductive voltage is higher than safe voltage, based on which relative prevention measures have been put forward, and these provide references for safety operation and maintenance of traction power supply system.
