[0002] High-voltage electricians are electricians who apply voltage, current, power, frequency, temperature and other factors to equipment at the same time, causing it to not work properly or even damage electrical equipment. The working principle of high-voltage electricians is to use high-voltage power supply to lead equipment or lines out of the earth through insulating materials, so that it is separated from the ground or suspended in the air, or various operations are performed in the air, so that the equipment cannot work properly. "High voltage" has many meanings, such as artificial electric shock applied to high-voltage power grids, application of high-voltage electric shocks and breakdown caused by discharge of high-voltage insulators.

[0003] Before carrying out actual high-voltage electrician work, workers need to undergo a high-voltage electrician assessment.

[0028] At the same time, the two wind direction indicator lights 2 are both powered by 12V DC, and the control board controls the on and off of the two wind direction indicator lights 2 through two sets of relays to simulate the three states of no wind in the upwind direction and downwind direction;

[0029] Furthermore, a circuit breaker and a control panel are provided inside the power box 10, and the touch screen integrated machine is provided on one side of the power box 10.

After comparing the software with the correct operation steps, the assessment score will be directly obtained and uploaded to the examination server platform for the trainees to query the score.

[0034] Embodiment 2:
