HVDC contactor for charging system
Update:08-03-2023
A high-voltage DC contactor for a charging system, which includes a housing, a cover plate is installed on the top of the housing, two DC contactors are placed side by side in the inner cavity of the housing, and the incoming and outgoing lines of the two DC contactors are connected to the The circuit board assembly placed on the upper part of the inner cavity of the housing is connected, the circuit board assembly is connected to the terminal, and the terminal is fixed on the cover plate; epoxy resin is filled between the housing and the outer wall of the DC contactor, and the DC contactor The inner cavity of the arc extinguishing device is filled with inert gas; the external power supply equipment is connected with the contacts of two DC contactors. The utility model connects two independent DC contactors in parallel to form a high-voltage DC contactor, and the circuit board assembly is used to plan The distribution of the incoming and outgoing lines of the contactor reduces the size of the contactor and improves the synchronization of the two DC contactors; the two DC contactors jointly carry the output power of the external equipment, which can meet the power requirements of high-voltage equipment .
