THE PREVENTION DEVICE OF IMPULSE CURRENT FOR LOCAL GOVERNOR

摘要

The present invention relates to a pressure regulator that changes the high-pressure gas supplied through a pipe buried underground to low pressure and supplies it to a demand destination. It is related to the shock current inflow prevention device of the local regulator to prevent damage to the remote terminal unit.;The present invention is made by the impact current flowing through the gas pipe of the medium / low pressure to be canceled through the Mg anode buried through the Mg anode and the bidirectional diode to prevent the impact current from flowing into the local pressure regulator.;Gas, constant pressure, shock current, protection
