[0002] During the use of power equipment, a large amount of current may sometimes be generated or flow through it, causing high voltage in the power equipment. In this case, once leakage occurs in the power equipment, it will cause great harm to human health. Therefore, in order to ensure the normal use of power equipment, the power equipment needs to be tested with high-voltage simulated loads before leaving the factory, and the operation of the power equipment under different loads must be monitored to ensure the safety and stability of the power equipment under high voltage conditions.
[0003] After searching, the utility model with application number CN202121545130.5 discloses an adjustable resistive load test device for high-voltage power supply, which relates to the field of resistive load test technology.

A first probe 8 is embedded on the stabilizing plate 9. The first probe 8 is electrically connected to the device to be tested. A plurality of ventilation holes 101 are provided on one side of the test box 1. Since there are many wires in the test box 1, the wires will continuously release heat as the voltage continues to increase during the test process of the test box 1. The ventilation holes 101 can ventilate and dissipate heat inside the test box 1.
[0024] A fixed block 10 is welded on the other side wall of the test box 1, and a lifting mechanism 6 is fixedly installed on the fixed block 10 to facilitate testing of the equipment under test at different heights.

A moving rod 703 is welded inside the moving seat 701, and a sliding sleeve 702 is sleeved on the moving rod 703. There is a damping connection between the sliding sleeve 702 and the moving rod 703. A second probe 704 is fixedly installed on the bottom surface of the sliding sleeve 702. The position of the second probe 704 can be adjusted through the sliding sleeve 702 to facilitate the electrical connection point of the equipment under test.
[0025] A door 3 is hinged on one side of the test box 1, and a handle 301 is welded on the door 3. A voltage controller 5 is embedded on the side of the door 3 away from the handle 301. A display screen 4 is also fixedly installed on the door 3. In combination with the voltage controller 5, a load test can be performed on the equipment to be tested, and then the test results can be observed through the display screen 4. Support legs 2 are respectively welded at the four corners of the bottom surface of the test box 1, and one end of the support legs 2 is fixedly installed with an anti-slip pad 201 to increase the stability of the overall device.

A lifting rod 605 is welded on one side of the slider 603. One end of the lifting rod 605 is fixed on the moving seat 701. After the motor 601 is started, it drives the slider 603 on the screw rod 604 to move, thereby controlling the lifting rod 605 to adjust the height. A limiting groove is also provided on the inner side wall of the test box 1. A limiting block 602 is fixedly installed on the other side of the slider 603.

The probe head 802 is pressed against the probe head 802 under the action of the spring 803. The motor 601 is started to control the slider 603 to descend, driving the moving mechanism 7 to descend and contact the device to be tested. Then, the sleeve 702 is used to adjust the position of the second probe 704 so that the second probe 704 is in contact with the device to be tested. With the support of the lifting mechanism 6, the second probe 704 and the first probe 8 are electrically connected to the device to be tested to ensure subsequent normal detection. After closing the box door 3, the voltage controller 5 is opened to perform a high-voltage load test on the device to be tested, and the staff can record the data according to the display screen 4.
