Description
Summary:A scheme of an automatic discharge device for protection against the switching overvoltage based on a controlled vacuum discharger was proposed. The discharge device is designed for shunting the reactor of the traction substation and inductance of the dc traction network during switching overloads accompanied by the power outage. Results of the experimental research and simulation of switching characteristics of such device are presented.
