When moving the cabinet body 700, the operator adjusts the height of the adjusting legs 920 to a position less than the height of the rollers 910, so that the bottom surface of the adjusting legs 920 is higher than the rolling contact point of the rollers 910, and the cabinet body 700 is moved by the rolling contact of the rollers 910 with the ground, so that the movement of the cable fault simulation training device 10 is more convenient. When the rollers 910 are moved to a suitable position, the operator adjusts the height of the adjusting legs 920 to a position greater than the height of the rollers 910, so that the bottom surface of the adjusting legs 920 is lower than the rolling contact point of the rollers 910, and the adjusting legs 920 provide support and fixation for the cabinet body 700, and the adjusting legs 920 can be leveled according to the flatness of the ground.

Then, the trainer opens the lock of the power module 930 to provide power for the device. After the trainer takes out the teaching aids and the circuit testing instrument from the tool box 710 and the support 720 and fixes them, the trainer selects the fault simulation type through the teacher console 330, so that the central control module 400 mobilizes the fault simulation module 200 according to the instruction, the fault simulation module 200 sets the corresponding fault on the cable line 100. The human-computer interaction module 300 displays the start of timing and the training content, and the students can use the circuit testing instrument to connect the measurement terminal 120 on the cable line 100 to troubleshoot. After the students locate the fault, the teacher console 330 displays the fault point position and the troubleshooting process, the human-computer interaction module 300 displays the troubleshooting time and the success prompt, and then the trainer explains according to the display content on the teacher console 330 and the measurement process of the students, and resets the device after the end, returns the circuit testing instrument, and closes the dustproof plate 800 and disconnects the power supply.
