Zusammenfassung: | The utility model discloses a low-voltage direct-current hybrid solid-state circuit breaker device, and the device comprises a main current branch which is used for automatically disconnecting a moving contact and a static contact when a fault current is generated, and achieving the protection of a circuit; the commutation branch is used for realizing conduction according to the pulse signal output by the driving module and realizing disconnection according to the signal output by the driving module when the fault current is completely transferred to the commutation branch; the energy consumption branch is used for realizing conduction based on overvoltage instantaneously generated by the circuit when the current conversion branch is switched off, and absorbing residual energy generated by the fault current so as to clear the fault current; the detection module is used for acquiring a line current and outputting a control signal to the driving module when the line current is greater than a preset current thre |
