随着生产能力的不断扩大 ,我厂供电系统的容量也不断增加 ,使得系统的对地电容越来越大。当发生单相电弧接地时 ,由于系统中的电感和电容作用 ,极易引起系统震荡而产生过电压 ,危害系统的安全供电 ,损坏设备 ,给电力系统的安全稳定运行造成影响。我厂第二水源地 6ｋＶ架空线路
With the continuous expansion of production capacity, the power supply system of our factory is also increasing, making the system capacitance to ground more and more. When a single-phase arc is grounded, due to the effect of inductance and capacitance in the system, it can easily cause system oscillation and generate over-voltage, which may endanger the safe power supply of the system and damage the equipment, thereby affecting the safe and stable operation of the power system. I plant the second source of 6kV overhead lines
