[0024] Example: Please refer to Figures 1-5 for a partial discharge test auxiliary device, which includes a detachable handheld rod 1. The detachable handheld rod 1 is composed of three detachable rod sections 11, wherein the connection between the detachable rod sections 11 is a threaded connection.

[0025] An angle adjustment shaft 2 is installed on the outer wall of the top of the detachable handheld rod 1. A slot 3 is opened on the outer wall of the angle adjustment shaft 2. An ultrasonic sensor 4 is inserted and installed on the inner wall of the slot 3. A buckle fastener 5 is installed on the outer wall of the detachable rod section 11. A movable main equipment bracket 6 is installed at one end of the buckle fastener 5. A partial discharge detection device 7 is set on the base surface of the movable main equipment bracket 6.

An installation groove 9 is opened on the outer wall of the detachable rod section 11. A support component 10 is installed on the inner wall of the installation groove 9.

[0026] The slot 3 physically secures the ultrasonic sensor 4 to the operating rod, ensuring that the ultrasonic sensor 4 will not loosen or fall off during use, thus guaranteeing measurement stability. At the same time, the slot 3 provides a certain degree of protection for the ultrasonic sensor 4, preventing bumps and external dust and impurities from entering, thereby extending the service life of the ultrasonic sensor 4. The standard slot 3 design makes the installation and removal of the ultrasonic sensor 4 simple, and also facilitates later maintenance and replacement.

[0027] The movable main equipment bracket 6 can be easily moved to the required position, providing users with a stable and reliable support point to adapt to the needs of the working environment. By adjusting the height and position of the bracket, users can easily reach the required working height, reduce unnecessary physical fatigue, and thus improve work efficiency.

[0028] The detachable handheld pole 1 consists of three detachable pole sections 11. The detachable pole sections 11 can be connected and separated by simple rotation. The appropriate length can be selected according to the height of use during operation. The biggest feature of the detachable pole section 11 is its flexibility. Users can easily adjust the length of the detachable handheld pole 1 according to actual needs. This design can not only adapt to various heights during operation, but also make it easy to carry and save space, thereby saving costs in the process.

[0029] The main functions of the angle adjustment shaft 2 include controlling the movement and positional accuracy of the machine, adjusting the relative position and angular relationship between equipment components to improve the flexibility and ease of operation of the equipment.

[0030] In this embodiment, specifically referring to Figures 1, 2, 3, 4, and 5, the support assembly 10 includes a rotating rod 1001, which is embedded in the inner wall of the mounting groove 9. An L-shaped fixing frame 1002 is rotatably connected to the outer wall of the rotating rod 1001. A limiting housing 1003 is installed at one end of the L-shaped fixing frame 1002. A magnetic adsorption block 1004 is embedded in the outer wall of the limiting housing 1003. A fixing block 1005 is installed on the outer wall of the L-shaped fixing frame 1002. An extension rod 1007 is rotatably connected to the outer wall of the fixing block 1005 via a rotating shaft 1006. The magnetic adsorption block 1004 is magnetically connected to the outer wall of the extension rod 1007.

[0031] Among them, the angle adjustment shaft 2 is located on one side of the movable main equipment bracket 6. The partial discharge detection device 7 is connected to the ultrasonic sensor 4 through the connecting line 8 and the connection method is electrical connection, so that the device is powered on, and then the partial discharge detection device 7 controls the ultrasonic sensor 4 to be powered on and operated. The slot 3 has an L-shaped cross-section. The mounting slot 9 has two sets and is located on the outer wall of the detachable rod section 11 respectively. The rotating rod 1001 has two sets and is located on the inner wall of the mounting slot 9 respectively. The limiting housing 1003 has a concave cross-section.

[0032] In operation, the partial discharge test auxiliary device of this scheme consists of a detachable handheld rod 1 composed of three detachable rod sections 11. The detachable rod sections 11 can be connected and separated by simple rotation. The appropriate length can be selected according to the operating height. Simultaneously, the slot 3 physically fixes the ultrasonic sensor 4 onto the operating rod, ensuring that the ultrasonic sensor 4 will not loosen or fall off during use, thus guaranteeing measurement stability. Adjusting the angle adjustment shaft 2 allows the ultrasonic sensor 4 to be adjusted to a suitable position and angle. Subsequently, the partial discharge auxiliary device can be used to adjust the ultrasonic sensor 4... The detachable handheld pole 1 is extended by combining with detachable pole sections 11 to reach the desired position. By selecting an appropriate height, the ultrasonic sensor 4 can be brought closer to the electrical equipment under test for more accurate detection of internal insulation and conductor connections. At the same time, the ultrasonic sensor 4 generates an electrical signal, which is transmitted to the partial discharge detection device 7 through the connecting line 8, so that the partial discharge detection device 7 can display the signal. This eliminates the need for workers to work at height for extended periods, ensuring personal safety and improving work efficiency. It also solves the problem that testing high-altitude electrical equipment requires workers to work at height for extended periods, and that it is difficult to adjust the sensor angle for seamless detection at high altitudes.

[0033] By pulling the L-shaped fixing bracket 1002, the L-shaped fixing bracket 1002 rotates on the outer wall of the rotating rod 1001, causing the L-shaped fixing bracket 1002 to move the extension rod 1007 out of the mounting slot 9. Then, by pulling the extension rod 1007, the extension rod 1007 rotates on the outer wall of the rotating shaft 1006. When the extension rod 1007 moves to one side of the magnetic adsorption block 1004, the magnetic adsorption block 1004 magnetically adsorbs and fixes the extension rod 1007. At the same time, the limiting housing 1003 provides limiting support for the extension rod 1007. When the support assembly 10 is fully extended, the support assembly 10 and the detachable handheld rod 1 form a triangular stable structure. When the test device is in the test interval, it is only necessary to place the detachable handheld rod 1 on the ground. The support assembly 10 provides more stable support for the detachable handheld rod 1, thereby solving the problem that the existing fixed bracket support structure is not practical and requires long-term hand holding, which leads to time and effort for the user.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
