APPARATUS FOR ELECTRIC EARTH WITH REVERSE SURGE DISCHAGING DEVICE

摘要

An apparatus for electric earth with a reverse surge discharging device is provided to discharge lighting flown in an electric earth rod safely by reducing electric earth resistance. An apparatus for electric earth includes an electric earth copper wire(1), a reverse surge discharging device, and an electric earth rod(5). The electric earth copper wire is connected to an electric facility. The reverse surge discharging device is composed of copper pipes(3,4) installed on an outer peripheral surface of the electric earth copper wire and needles radially installed on an outer peripheral surface of the copper pipe. The electric earth rod is connected at an end part of the electric earth copper wire.
