Abstract

The invention discloses a detection device applied to DC electric leakage of a V2G charging pile output DC charging gun, a shell and a joint are provided with a manual power-on and power-off safety structure, the manual power-on and power-off safety structure comprises an inner wheel, a driving lever, a stop block and a stop lever, the driving lever is arranged outside the inner wheel, the driving lever extends out of a hole in the side wall of the shell, a baffle block is arranged at the conductive block at the front end of the inner wheel; a baffle rod is arranged at the rear end of the joint; the electric leakage detection equipment protection structure (3) internally comprises a direct current electric leakage detection module, the direct current electric leakage detection module comprises an MCU control module, a power supply electrically connected with the MCU control module and a direct current electric leakage detection sensor, and the direct current electric leakage detection sensor is electrically connected with a charging gun through a direct current contactor; a direct-current electric leakage detection function is added to the output direct-current charging gun (connected with an automobile power battery during discharging) of the V2G direct-current charging pile, and when electric leakage occurs, the direct-current charging gun is disconnected, so that personal and property loss caused by electric leakage is avoided.

Description

technical field [0001] The invention relates to the field of DC leakage detection devices for charging guns, in particular to a detection device for DC leakage of DC charging guns output by V2G charging piles. Background technique [0002] V2G DC charging piles can charge and discharge bidirectionally. When discharging, the vehicle power battery is used as the power supply terminal, the voltage reaches 750V-1000V, and the current can reach 50-250A. The charging piles are used outdoors, which is likely to cause the risk of leakage. [0003] The basic characteristics of the DC leakage current sensor are as follows: [0004] 1. The DC leakage current sensor adopts the technology of magnetic modulation (or called fluxgate FluxGate). The compensation current generated by the internal square wave oscillator compensates the primary side current to achieve magnetic field balance. At this time, the output value VM is accurate Reflect the primary side current, mainly used for small D...
