[0002] Insulating rods are essential safety tools for inspection and maintenance in the power industry. To ensure the good performance of insulating rods, they must be subjected to withstand voltage tests regularly every year to detect their insulation. Most of the insulating rods used in substations are three-section insulating rods, which are connected by rotating and fixing the three ends when in use. At present, when conducting withstand voltage tests on insulating rods, clips are usually used to clamp the two ends of the insulating rods for testing, or they are laid flat for segmented testing. However, due to the different lengths of the insulating rods used and the cylindrical structure of the insulating rods, the two ends cannot be firmly fixed during the experiment, which will lead to unstable connections at both ends. There are also certain deviations in the data of the withstand voltage tests, and the insulating rods connected by clips Usually it needs to be placed on an insulating object for a withstand voltage test without any protective measures around it. Therefore, there are certain safety hazards during the experiment. In addition, due to the different sizes and lengths of the insulating rods, some test devices cannot adjust the test length when doing a withstand voltage test. They can only be clamped in the middle and upper part of the insulating rod and cannot directly contact the two ends of the insulating rod. As a result, some sections of the insulating rod cannot be measured, and accurate measurement results cannot be made for the insulating rod in an all-round way. This does not meet national testing standards and cannot effectively guarantee the withstand voltage performance of the insulating rod.
