[0002] Partial discharge is an important characterization phenomenon of insulation deterioration and an early warning signal for important hidden dangers of high-voltage insulation faults. Timely detection of partial discharge is of great significance for the insulation faults of high-voltage electrical equipment and is an important means to avoid major accidents. The utility model patent with the patent authorization announcement number CN219957761U discloses a UHF partial discharge sensor installation structure, including a cabinet wall, a mounting plate and a sensor. The mounting plate is detachably connected to the cabinet wall. One end of a connecting rod is connected to the side of the mounting plate away from the cabinet wall, and the other end of the connecting rod is connected to a limiting plate. A clamping seat is connected to the back side of the sensor, and a clamping groove corresponding to the limiting plate is provided on the clamping seat. An elastic clamping mechanism is provided at the notch of the clamping groove. In the utility model, the mounting plate and the cabinet wall are connected by screws, and the screws are hidden in the settling grooves to avoid protrusion and interference during the installation of the sensor. The clamping groove of the clamping seat on the sensor is clamped with the limiting plate, the connecting rod slides into the sliding port, and the limiting protrusion on the elastic claw limits the connecting rod to prevent it from separating, quickly completing the fixed installation of the sensor.

The plug 85 is slidably connected to the sliding plate 5. The screw rod 81 is rotatably connected inside the sliding plate 5 through a bearing. Knobs 82 are fixedly connected to both the upper and lower ends of the screw rod 81. Two symmetrically distributed connecting bars 83 are threadedly connected to the outside of the screw rod 81. The screw rod 81 is provided with a right-handed thread and a left-handed thread, and the right-handed thread and the left-handed thread are symmetrically distributed on the screw rod 81. By designing the screw rod 81, the rotation of the screw rod 81 can realize the movement of the two connecting bars 83 in opposite directions. The connecting bars 83 are slidably connected to the sliding plate 5. The connecting bars 83 are in contact with the plug 85. A limiting block 84 is fixedly connected to the end of the connecting bar 83 close to the plug 85. The limiting block 84 is slidably connected to the plug 85. A limiting groove 86 is opened inside the plug 85. The limiting block 84 is slidably connected to the inside of the limiting groove 86. By designing the limiting groove 86, the limiting block 84 can be slidably inserted into the plug 85. By designing the installation mechanism 8, the installation and use of the sensor body 6 are more stable.

[0025] Please refer to Figure 1 , Figure 4 , Figure 5, the adjusting mechanism 9 includes a groove 91. The groove 91 is formed inside the mounting plate 2. A convex block 92 is slidably connected inside the groove 91. The number of grooves 91 is multiple, and the multiple grooves 91 are symmetrically distributed on the mounting plate 2. By designing multiple grooves 91, the convex block 92 can slide into the grooves 91 at different positions. The convex block 92 is slidably connected to the slider 4. A connecting seat 93 is slidably sleeved outside the convex block 92. The connecting seat 93 is fixedly connected to the slider 4. A guide rod 94 is fixedly connected inside the connecting seat 93.

The installation is convenient and fast, and compared with the clamping method, the installation and use of the sensor body 6 are more stable.

[0027] When it is necessary to adjust the use position of the sensor body 6, directly push the sensor body 6. The sensor body 6 drives the sliding plate 5 to move. The sliding plate 5 drives the slider 4 to slide along the fixed rod 3. At the same time, the slider 4 drives the connecting seat 93 and the convex block 92 to move. The convex block 92 can slide along the inclined surface of the groove 91. The convex block 92 is squeezed and will move horizontally along the guide rod 94. The convex block 92 will squeeze the spring 95, and at the same time, the convex block 92 can be made to slide out of the groove 91. As the slider 4 slides, under the elastic action of the spring 95, the convex block 92 can slide into the grooves 91 at different positions, and the cooperation between the convex block 92 and the grooves 91 at different positions can be realized. Furthermore, the relative position between the sliding plate 5 and the mounting plate 2 can be adjusted, and the use position of the sensor body 6 can be flexibly adjusted after installation.
