[0023] Furthermore, ten groups of first mounting holes 2 are provided, two groups of second mounting holes 3 are provided, the number of second mounting holes 3 in each group is five, four groups of third mounting holes 4 are provided, and ten groups of first mounting holes 2 correspond to ten groups of connecting wires 12, and the two are connected under the connection of the connecting terminal 7.

[0024] Further, two groups of fourth mounting holes 5 are provided, and three groups of fifth mounting holes 6 are provided, and the diameters of the fourth mounting holes 5 and the fifth mounting holes 6 are smaller than the diameter of the second mounting holes 3 .

[0025] Furthermore, one side of the terminal block 7 is fixedly connected to the surface of the PCB board 1 through the first mounting hole 2, and the other side of the terminal block 7 is installed on the surface of the connecting wire 12. Through the action of the terminal block 7, the connecting wire 12 can be installed on the surface of the PCB board 1.

[0026] Further, the relay 8 is fixedly connected to the surface of the PCB board 1 through the second mounting hole 3, the slide switch 9 is fixedly connected to the surface of the PCB board 1 through the third mounting hole 4, the resistor 10 is fixedly connected to the surface of the PCB board 1 through the fourth mounting hole 5, and the LED lamp 11 is fixedly connected to the surface of the PCB board 1 through the fifth mounting hole 6. The relay 8 can be mounted on the PCB board 1 and used through the second mounting hole 3, the slide switch 9 can be mounted on the PCB board 1 and used through the third mounting hole 4, and the two ends of the resistor 10 can be inserted into it through the two sets of fourth mounting holes 5. In order to achieve the effect of its installation, the LED lamp 11 can be installed on the PCB board 1 and used through the three groups of fifth mounting holes 6, and the LED lamp 11 adopts a two-color common anode lamp. The simulated circuit breaker is plugged into the control cable jack of the feeder terminal device. The LED lamp 11 is lit, which can simulate the indication of the circuit breaker opening and closing status: the green light represents the circuit breaker opening, and the red light represents the circuit breaker closing; the opening and closing are controlled by the opening and closing handle of the feeder terminal device. After the handle is used to close the circuit, the red light is lit, and the closing signal of the feeder terminal device is uploaded at the same time. After the handle is used to open the circuit, the green light is lit, and the opening signal of the feeder terminal device is uploaded at the same time.

[0027] Furthermore, ten groups of connecting wires 12 are provided, one end of the connecting wires 12 is fixedly connected to the surface of the wiring terminal 7, and the other end of the connecting wires 12 is installed on the surface of the aviation plug 13 through the sixth mounting hole 14, so that the aviation plug 13 and the wiring terminal 7 are connected through the connecting action of the connecting wires 12.

[0028] Furthermore, ten groups of sixth mounting holes 14 are provided, and the size of the sixth mounting holes 14 is larger than the size of the connecting wire 12. Under the action of the sixth mounting holes 14, the connecting wire 12 is installed on the aviation plug 13 through the sixth mounting holes 14, thereby achieving a connection effect with the aviation plug 13.

[0029] Working principle: First, assemble the simulated circuit breaker so that the terminal 7, relay 8, slide switch 9, resistor 10 and LED lamp 11 are installed on the surface of PCB board 1 through the first mounting hole 2, the second mounting hole 3, the third mounting hole 4, the fourth mounting hole 5 and the fifth mounting hole 6 respectively, and connect the connecting wire 12 connected to the aviation plug 13 with the terminal 7 by using a screwdriver under the action of the screw, and open the slide switch 9. After a set of switches on the line fail to be remotely controlled, when the operation and maintenance personnel investigate the cause of the failure on site, they do not need to remove the feeder terminal device to go back for testing, but directly insert the simulated circuit breaker into the failed feeder terminal device, and let the master station remotely control the switch again. If the remote control fails, it means that there is a problem inside the feeder terminal device. If the remote control succeeds, the circuit breaker is judged to be faulty. When it is suspected that the feeder terminal device on the line trips abnormally, it does not need to be removed on site, but the simulated circuit breaker is plugged in, and a handheld relay protection instrument is used to perform a relay protection test to observe the tripping of the simulated circuit breaker. Plug the simulated circuit breaker into the feeder terminal device on site to perform switch remote control, thereby improving the remote control success rate index. When the circuit breaker on the line stores energy abnormally, you can plug in a simulated circuit breaker to measure whether the voltage of the pin is sufficient. If the voltage is greater than 24V, it proves that the internal energy storage mechanism of the circuit breaker on site is faulty. If the voltage is less than 24V, it proves that the energy storage output voltage of the feeder terminal device is abnormal. Low voltage or no voltage causes the circuit breaker on site to be unable to store energy abnormally.
