【摘要】 本文针对电力系统中单侧电源电力线路发生单相接地短路故障的情况进行分析,首先对故障进行实际录波,然后又对故障进行建模分析及公式推导,得出上述故障情况下的电流特点:电源侧除故障相有故障电流外,非故障相亦有大小相等、相位相同的电流,非电源侧三相均有电流,且大小相等、相位相同。更多还原

【Abstract】 To the question of phase-to-earth fault happening on the Single Source, the article not only shows the wave of the current but also gives the model and makes a detail analysis, and then gets the current specialties in this case: at the power supply side, the fault phase’s current is great and the other two phases’ one are not zero but have the same value and the same direction, and at the other side, three phases’ current have the same value and the same direction.更多还原
