The high and low voltage switchgear power test bench is an important tool in power equipment testing, which can comprehensively inspect the performance of the switchgear. However, due to its involvement in high and low voltage electrical operations, relevant precautions must be strictly followed during use to ensure personnel safety and the accuracy of test results.

Before operation, the operator must have professional knowledge of electricity, be familiar with the operation process of the test bench and the detection standards of the switchgear. A comprehensive inspection of the test bench should be carried out to check whether the appearance of the equipment is damaged, whether the connecting components are firm, and whether the instrument display is normal. At the same time, it is crucial to ensure good grounding of the test bench to prevent electrical leakage accidents. According to the testing requirements, set various parameters of the test bench reasonably, such as voltage, current, phase, etc. During the setting process, strictly follow the operating specifications of the equipment to avoid equipment damage or inaccurate test results caused by incorrect parameter settings.

Wiring is an important part of using a test bench. Choose a test line that meets the specifications to ensure good insulation performance and no damage. Connect according to the correct wiring diagram to ensure that the test line is firmly and reliably connected to the switchgear and test bench, avoiding virtual connections. During the connection process, it is important to distinguish between different voltage levels and circuits to prevent safety accidents caused by misconnection.

During the testing process, operators should always pay attention to the operating status of the test bench. Observe whether the displayed data of the instrument is within the normal range. If there is any abnormality, stop testing immediately and investigate the cause of the fault. It is strictly prohibited to touch live parts during the testing process to avoid the risk of electric shock. If parameter adjustment is required, it must be done with the power cut off.

After the test is completed, the power supply of the test bench should be turned off first, and then the test lines should be removed in order. Organize and analyze test data to ensure its completeness and accuracy. At the same time, it is necessary to clean and maintain the test bench, remove dust and debris from the surface of the equipment, check whether the components of the equipment are loose or damaged, and promptly repair and replace them.

When using the high and low voltage switchgear power on test bench, the operator should always ensure safetyfirst placeStrictly follow the operating procedures and pay attention to equipment maintenance and upkeep. Only in this way can the role of the test bench be fully utilized, providing strong guarantees for the safe and stable operation of power equipment.
