Complementary power supply type of scene intelligence circuit breaker

The utility model relates to a complementary power supply type of scene intelligence circuit breaker, including photovoltaic inverter, wind energy inverter, the battery, IGBT output circuit, the three -phase AC module of sampling, charging voltage detection module, protection value setting module, and digital signal processor, three -phase AC sampling circuit's output is connected to digital signal processor's ADC input channel, charging voltage detection module's output is connected to digital signal processor's the first IO of group mouth, protection value setting module's output is connected to digital signal processor's the second IO of group mouth, digital signal processor's the third IO of group antilinear optical coupling isolation IGBT drive module output control signal to IGBT output circuit. When the main line intermediate -current is worth above the protection, by digital signal processor inquiry charging voltage detection module's ADC input, work as battery positive voltage voltage just often, digital signal processor sends drive signal, controls IGBT output circuit and works, finally realizes the purpose of separating brake or combined floodgate.
