[0002] The function of the voltage-equalizing ring structure is to prevent side lightning strikes. It is suitable for AC voltage and can evenly distribute high voltage around the object to ensure that there is no potential difference between the various parts of the ring, thereby achieving the effect of voltage equalization.

[0003] For example, a high-stability equalizing ring with the authorization announcement number "CN219575272U" is provided with a fixing tube at the center of the upper ring body, which is connected to the inner side of the upper ring body through a bracket, and a deformable fixing plate is provided on the lower side of the fixing tube, and the outside of the fixing plate is locked by a fixing ring. The fixed tube structure is adopted, and the deformable fixing plate and the fixing ring at the bottom are cooperated to fix the main body below the end, thereby realizing the installation of the entire equalizing ring. It is convenient and fast in operation and has high safety. However, when the high-stability equalizing ring structure is used, it needs to be installed at the end of the insulator. Sometimes the high-stability equalizing ring structure needs to be outside the insulator, and the high-stability equalizing ring structure is fixed and cannot be adjusted. This requires the high-stability equalizing ring structure to be lengthened, that is, two or more high-stability equalizing ring structures are spliced. In addition, the high-stability equalizing ring structure is mostly operated at high altitude, which increases the operating difficulty of the high-stability equalizing ring structure and is not convenient for the operation and use of the high-stability equalizing ring structure.

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] Embodiment 1:

[0022] See also Figure 1-4 : In the present embodiment, a high-stability equalizing ring structure with retractable length includes an equalizing ring 1 and a sleeve 4. The right side of the front side of the equalizing ring 1 is fixedly connected to the rear end face of the sleeve 4. The equalizing ring 1 is connected to the neutral point of the arrester to ensure the uniformity of the voltage distribution in the arrester. When the arrester is in a high voltage state, the equalizing ring balances the voltage distribution by changing its own capacitance state, helping the arrester to maintain a stable working state. The inner wall of the sleeve 4 is connected to a telescopic structure 2, and the upper and lower sides of the front side of the equalizing ring 1 are respectively fixed with straight tubes 5, and the inner walls of the two straight tubes 5 are respectively slidably clamped with bent rods 6. The straight tube 5 is subjected to force to slide back and forth on the outer wall of the bent rod 6, and the inner sides of the two bent rods 6 are respectively connected to fixed structures 3, and the right side of the bent rod 6 is fixedly connected to the left side of the telescopic structure 2.

[0023] The telescopic structure 2 includes a cylinder 201 and a screw 202. The rear of the outer wall of the cylinder 201 is rotatably connected to the inner wall of the sleeve 4. The cylinder 201 is rotated by the bearing on the inner wall of the sleeve 4. The inner wall of the cylinder 201 is threadedly connected to the outer wall of the screw 202. A bracket 203 is fixedly connected to the front of the screw 202. The left end of the bracket 203 is fixedly connected to the right side of the bent rod 6. The bracket 203 supports the bent rod 6.

[0024] The cylinder 201 is clamped by an external tool in the telescopic structure 2, and then the cylinder 201 is rotated on the inner wall of the sleeve 4. The rotating cylinder 201 moves backward on the outer wall of the screw 202, and the moving cylinder 201 moves backward with the sleeve 4, and the sleeve 4 moves backward with the pressure-equalizing ring 1. Then the pressure-equalizing ring 1 moves backward with the straight cylinder 5 on the outer wall of the bent rod 6, so that the pressure-equalizing ring 1 can be extended. The above structure of rotating the cylinder 201 in the opposite direction will move in the opposite direction, thereby realizing telescoping, reducing the operating difficulty of the high-stability pressure-equalizing ring structure and facilitating the use of the high-stability pressure-equalizing ring structure.

[0025] The fixing structure 3 includes an arc plate 301 and a straight plate 302. The outer side of the arc plate 301 is fixedly connected to the inner side of the bent rod 6. The left and right sides of the arc plate 301 are respectively fixedly connected to the inner side of the straight plate 302. The inner wall of the straight plate 302 is threadedly connected with a first bolt 303. The first bolt 303 fixes the straight plate 302 and the pressure equalizing ring 1. A nut 304 is threadedly connected on the upper part of the outer wall of the first bolt 303. The inner sides of multiple straight plates 302 are tightly pressed against each other, and the inner sides of two arc plates 301 are tightly pressed against each other.

[0026] Working principle:

[0027] Pressure equalizing ring installation:

[0028] First, the inner wall of the equalizing ring 1 is sleeved with the outer wall of the insulator until the inner wall of the arc plate 301 is located at the connecting end of the insulator, and then the first bolt 303 and the nut 304 are clamped on the outer wall of the first screw rod 303 and rotated downward. The rotating nut 303 will move the upper straight plate 302 downward until the two straight plates 302 are pressed tightly. After the straight plates are pressed tightly, the two arc plates 301 will press against the connecting end of the insulator to complete the installation of the equalizing ring 1.

[0029] Extension and retraction adjustment of pressure equalizing ring:

[0030] The cylinder 201 is clamped by an external tool, and then rotated on the inner wall of the sleeve 4. The rotating cylinder 201 moves backward on the outer wall of the screw 202. The moving cylinder 201 moves backward with the sleeve 4. The sleeve 4 moves backward with the pressure-equalizing ring 1. Then the pressure-equalizing ring 1 moves backward with the straight cylinder 5 on the outer wall of the bent rod 6, so that the pressure-equalizing ring 1 can be extended. The above structure will move in the opposite direction when the cylinder 201 is rotated in the reverse direction, thereby realizing extension and retraction.

[0031] Embodiment 2:

[0032] See also Figure 1-4 : In this embodiment, a high-stability pressure-equalizing ring structure with retractable length also includes a curved plate 7 and a second bolt 8. The outer sides of the rear end faces of the two curved plates 7 are fitted with the front side of the pressure-equalizing ring 1, the outer sides of the front side of the curved plates 7 are threadedly connected to the outer wall of the second bolt 8, and the rear side of the outer wall of the second bolt 8 is threadedly connected to the front circular mouth of the pressure-equalizing ring 1.

[0033] Working principle:

[0034] After the pressure-equalizing ring 1 is installed, the corresponding curved plate 7 is selected to make the notch on the inner side of the curved plate 7 fit with the outer wall of the external insulator. At this time, the outer side of the curved plate 7 fits with the outer wall of the pressure-equalizing ring 1. Then the second bolt 8 is threaded from the right front to the rear through the curved plate 7 and connected with the front thread of the pressure-equalizing ring 1. The curved plate 7 can support the pressure-equalizing ring 1 and improve the stability of the pressure-equalizing ring 1.
