High-voltage distribution cabinet
High-voltage power distribution box: centralized power distribution method, compact, easy wiring, easy maintenance. High voltage contactor is controlled by the vehicle controller, configuration maintenance switch, convenient unexpected emergency off and easy maintenance. High voltage distribution box with multiple protection circuit, built-in high-voltage contactors, high voltage fuses, insulation test panels. High-voltage distribution cabinet insulation on the vehicle can be detected, for alarm and leakage protection. High-voltage distribution cabinet blessing workers has the following characteristics:
? When independent control of each high-voltage equipment and protection bus loop to ensure that the local device failure, vehicle safety;
? control panel with contactor detection circuit, by observing the indicator, available each contactor work;
? internal insulation monitoring module with positive and negative DC system insulation resistance to real-time monitoring. When the insulation resistance reaches the alarm set value, an alarm signal is emitted ground.
? There are internal short circuit protection, overvoltage, overcurrent protection improves the system stability, reliability, ease of use and reliability.
