110kV circuit breaker state simulator

The utility model relates to a 110kV circuit breaker state simulator. The device comprises a power switch, a back-row wire holder, a transformer, a loudspeaker, a mainboard, an indicating lamp and a cabinet. The mainboard comprises a power supply module, an MCU module, an interface module, an LED state indicator and a relay control module. The power module is used for supplying power. The power switch is used for controlling on-off of the power module. The MCU module is respectively connected with the interface module, the LED state indicator and the relay control module; the rear-row wire holder is used for being externally connected with a power supply and connected to the circuit breaker model; the 220V alternating current is connected with the power supply module in the mainboard through the transformer, and the MCU module in the mainboard is respectively connected with the loudspeaker and the indicating lamp. The 110kV circuit breaker state simulator can capture switching-on and switching-off direct curr
