| Abstract: | A new parallel gap lightning protection device is developed which has the capability of rapid arc extinction of power-flow current.Some key characteristics of the gap are as follows: huge heat capacity,responds time of arc extinction less than 5ms,cut off reliably and rapidly the power-flow current of the gap caused by inter-phase short circuit,reduce greatly the trip rate caused by power-flow current.The new gap lightning protection device has reasonable structure,easy installation,low price,good condition... |
