PE LINE PROTECTION SYSTEM FOR POWER SUPPLY AND CHARGING EQUIPMENT, AND POWER SUPPLY AND CHARGING EQUIPMENT

Abstract

The useful solution refers to the PE line protection system for the power supply and charging equipment, and the power supply and charging equipment, the PE line protection system for the power supply and charging equipment includes a control circuit (1) and a switch (2). The control circuit (1) is used to control the switch (2) which will interrupt the PE line when it receives a signal indicating an abnormal connection of the PE line transmitted by the power supply and charging equipment. It can be seen that when the PE line is connected abnormally and a faulty current flows into the PE line, for example, a live line or live wire is connected to the PE line, a DC fault current or an AC fault current will flow into the PE line. The switch (2) connected to the PE line can interrupt the PE line in time. This, on the one hand, avoids the possibility of electrical contamination of the metal parts of the equipment, prevents the risk of electric shock to the human body, ensures the safety of the entire charging process and allows the equipment to be charged safely without risk.
