[0023] In order to simulate the power outage state, when the cable part 5 is powered, the current is transmitted to the operating part 3 through the busbar part 4 for feedback and operation, and the vacuum circuit breaker 22 is controlled by the operating part 3 to disconnect the control circuit.

[0024] In order to achieve the above work, the specific process is as follows: the cable part 5 transmits the circuit signal to the programmable controller 34, the model of the programmable controller is FX2N-16MR, the control operation part 3 can control the vacuum circuit breaker 22, and control the state of the current transmitted by the cable part 5 in the bus part 4.

[0025] In some embodiments, the trolley part 2 includes a vacuum circuit breaker 22 and a circuit breaker 21 . The vacuum circuit breaker 22 is installed in the middle of the inner cavity of the cabinet 1 . The vacuum circuit breaker 22 is electrically connected to the circuit breaker 21 .

[0026] The vacuum circuit breaker 22 serves to disconnect the current of the entire power transmission cabinet, and its effect is controlled by the circuit breaker 21. After receiving feedback from the programmable controller 33, the vacuum circuit breaker 22 can control the circuit breaker 21 to disconnect the circuit, so as to stop power supply to the entire equipment.

[0027] In some embodiments, the operating part 3 includes a display screen 31, a diffuse reflection sensor 34 and an operation button 32.

[0028] The signal from the diffuse reflection sensor 34 is transmitted to the programmable controller 33. The programmable controller 33 performs logical judgment according to the programmed program, and the result is displayed on the display screen 31. Then the operation button 32 is operated to control the programmable controller 33.

[0030] In order to achieve stable current transmission in the entire power transmission cabinet, the setting of the main busbar 42 and multiple branch busbars 43 enables the current to be transmitted stably in multiple directions. The pressure relief pipe 41 discharges the high temperature generated inside the busbar part 4 for pressure relief, and can stably receive the current transmission from the cable part 5.

[0035] In some embodiments, the current transformer 51 is electrically connected to the diffuse reflection sensor 34 to provide timely feedback on the power situation.

[0036] The working principle of the present invention is described below with a preferred embodiment: under the effect of the cable part 5 being connected to the power, the current is transmitted to the operating part 3 through the busbar part 4 for feedback and operation, and the vacuum circuit breaker 22 is controlled by controlling the operating part 3 to disconnect the control circuit, allowing the user to control the voltage released from the cable part 5 to simulate the power outage operation. The vacuum circuit breaker 22 plays the role of disconnecting the current of the entire power transmission cabinet, and its effect is controlled by the circuit breaker 21. After the vacuum circuit breaker 22 receives the feedback prompt from the programmable controller 33, it can control the circuit breaker 21 to disconnect the circuit. The signal of the diffuse reflection sensor 34 is transmitted to the programmable controller 33, and the programmable controller 33 performs logical judgment according to the written program, and the result is displayed on the display screen 31.
