Two-wire and three-wire compatible high-voltage box

Abstract

The utility model relates to the technical field of switches, in particular to a two-wire and three-wire compatible high-voltage box, which comprises a neutral wire N, an energy storage battery cluster main control unit BCU, a power supply interface, a main circuit breaker, a fuse, a Hall current sensor, a positive contactor, a negative contactor, a positive pre-charging contactor, a negative pre-charging contactor, a direct-current conversion module and a pre-charging resistor, the fuses comprise a fuse FU1 and a fuse FU2; the Hall current sensors comprise a Hall current sensor HALL2 and a Hall current sensor HALL1; aiming at the technical problem that a high-voltage box in the prior art cannot be compatible with a two-wire system and a three-wire system, the high-voltage box can realize the functions of the two-wire system and the three-wire system at the same time, and realizes the compatibility of the two wires and the three wires.
