求翻译：（2）感应过电压。当雷云在架空导线上方，由于静电感应，在架空导线上积聚了大量的异性束缚电荷，在雷云对大地放电时，线路上的电荷被释放，形成的自由电荷流向线路的两端，产生很高的过电压，此过电压会对电力网络造成危害。是什么意思？

(2) induced over voltage. When the thunderclouds above the overhead wires, due to electrostatic induction, accumulate in the overhead wires, a large number of heterosexual bound charge in the thundercloud to the earth discharge, the line charge is released, the formation of free charge to the line a

(2) inductive voltage. In the clouds overhead wires, and due to electrostatic induction, the overhead power lines on the wire has accumulated a large number of the opposite sex in bondage, and charge-cloud to ground discharges on the line, the charge is released in a charge to the freedom of the two

(2) the induced voltage. When thundercloud in the overhead wires above, due to the electrostatic induction, amassed a large number of specific constraints on the overhead charges, when thundercloud on the ground discharge, charge on the line were released to form free of charge flow to the ends of t
