摘要
谐振接地系统中消弧线圈的残流稳定时间是一个很重要的概念,对快速熄灭电弧,保障人身和设备安全有重要的意义。详细分析了影响消弧线圈残流稳定时间的各种因素,指出残流稳定时间受系统参数影响,且与接地随机参数有关,主要取决于暂态励磁电流的衰减速度。文中还澄清了现有一些关于消弧线圈补偿速度的错误观点。
In resonance grounding system, the decay time for residual current of arc suppressing coil is a very important parameter for suppressing arc rapidly, ensuring equipments & personal safety. The factors affecting the decay time for residual curI'ent are analyzed in detail. It is indicated that the decay time for residual current is affected by system parameters and related with grounding random parameters, hut it mainly depends on the decaying speed of transient current. This paper also clarifies the wrong viewpoints on compensation speed for the are suppressing coil.
