Mainly used for the packaging of epoxy-sealed gas-filled high-voltage DC contactors. In the power battery system of electric vehicles, high-voltage DC contactors are used to control the charging and discharging circuits of electricity. When the vehicle is charging, the contactor closes, allowing current to flow from the charging pile into the battery; when charging is completed or an abnormal situation occurs, the contactor quickly disconnects to ensure battery safety. In the drive motor control system, it can precisely control the motor's startup, stop, and speed regulation, ensuring the smooth operation of the vehicle. For example, during acceleration, the contactor connects stably, providing strong current support for the motor; during braking, the contactor disconnects in a timely manner to achieve energy recovery.
