PE LINE PROTECTION SYSTEM FOR POWER UTILIZATION AND CHARGING APPARATUS, AND POWER UTILIZATION AND CHARGING APPARATUS

A PE line protection system for a power utilization and charging apparatus, and a power utilization and charging apparatus, the PE line protection system for a power utilization and charging apparatus comprises a driving circuit (1) and a switch (2). The driving circuit (1) is used for controlling the switch (2) to cut off a PE line upon reception of a signal for indicating the abnormal connection of the PE line that is transmitted by the power utilization and charging apparatus. It can be seen that when the PE line is abnormally connected and a wrong current flows into the PE line, for example a live line or a live conductor is connected to the PE line, a DC error current or an AC error current flows into the PE line, the switch (2) connected to the PE line can cut off the PE line in time, which on one hand avoids the possibility of being electrified of a metal part of the apparatus, prevents electrical shock hazards to a human body, ensures the safety of the whole charging process, and enables the apparatus to be charged safely without risk.
