Hybrid flexible arc extinguishing system and use method

The invention discloses a hybrid flexible arc extinguishing system and a use method, and relates to the technical field of active arc extinguishing of non-effective ground faults of a power distribution network. In order to solve the problem of arc extinction of a delta wiring power distribution network in practice, the invention provides a hybrid flexible arc extinguishing system, which comprises a power source conversion module, a rapid switching switch, an inverter power supply, an isolation transformer and an injection transformer; a power source conversion module is used for converting power supply voltage into reverse-phase fault phase power supply voltage, and neutral point voltage which is equal to the fault phase power supply voltage in amplitude and reverse phase can be generated by combining the rapid switching switch and accessing a neutral point of the system through the inverter power supply and the injection transformer.. According to the hybrid flexible arc extinguishing system provided by the
