Description

Technical Field

[0001] The utility model relates to a pressure equalizing ring, in particular to an ultra-high voltage anti-breakdown pressure equalizing ring. Background Art

[0002] The main function of the grading ring is voltage grading. It is suitable for AC voltage. It can evenly distribute high voltage around the object to ensure that there is no potential difference between the various parts of the ring, so as to achieve the effect of voltage grading. According to different uses, the grading ring can be divided into arrester grading ring, lightning protection grading ring, insulator grading ring, transformer grading ring, high-voltage test equipment grading ring, transmission and transformation line grading ring, etc. Grading rings can be divided into aluminum grading rings, stainless steel grading rings, iron grading rings, etc. according to different materials; similar to the grading ring are shielding rings and grading shielding rings.

[0003] At present, the grading rings used in my country's high-voltage electrical appliances and power systems (substations, high-voltage lines, etc.) are mainly made of aluminum alloy. Generally, the surface of the grading rings is required to be polished. Especially when ultra-high voltage grading rings are used, the internal anti-puncture ability needs to be considered.

[0004] In the prior art: CN201922390435.2 An inflatable pressure-equalizing ring, an inflatable pressure-equalizing ring, comprising a pressure-equalizing ring body, the pressure-equalizing ring body being divided into a pressure-equalizing ring part A and a pressure-equalizing ring part B, the pressure-equalizing ring part A and the pressure-equalizing ring part B being welded to each other, and an inflatable cavity being arranged inside the pressure-equalizing ring part A and the pressure-equalizing ring part B, an air inlet being arranged at the lower end of the pressure-equalizing ring part A, an aluminum block part being arranged on the air inlet to match the air inlet, the aluminum block part being composed of an aluminum block head and an outer end face of the aluminum block, the aluminum block head and the outer end face of the aluminum block being welded to each other.

[0005] Although in the prior art the inner wall of the pressure equalizing ring can be protected when nitrogen or other gases are injected into the inner wall of the pressure equalizing ring, rust spots can be effectively avoided, making the use of the pressure equalizing ring safer, and the pressure equalizing ring can be better suspended or fixed and connected in other ways by relying on the movable support part, the local anti-puncture ability of the pressure equalizing ring in the prior art is relatively weak. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the utility model provides an ultra-high voltage anti-breakdown equalizing ring.

[0007] The utility model is implemented by the following technical scheme: an ultra-ultra-high voltage anti-breakdown equalizing ring is provided with a pressure equalizing ring, an assembly platform is provided at the bottom of the pressure equalizing ring, the assembly platform is divided into a left platform and a right platform, the left platform and the right platform and the pressure equalizing ring are connected by welding, locking holes are provided on the left platform and the right platform, the locking holes adopt locking threaded holes, an anti-breakdown component is provided inside the pressure equalizing ring, the anti-breakdown component is an anti-breakdown inner cover, a circular hole is provided on the inner wall of the pressure equalizing ring, a long screw is provided on the anti-breakdown inner cover, and the long screw and the circular hole on the inner wall of the pressure equalizing ring are assembled.

[0008] An assembly platform is arranged on the anti-penetration inner cover, a threaded hole is arranged on the assembly platform, and a long screw is arranged in the threaded hole.

[0009] The anti-breakdown inner cover is a stainless steel inner cover, and a filling impact groove is arranged on the inner wall of the stainless steel inner cover, and a shielding plate is filled in the filling impact groove.

[0010] The filling and resisting groove is provided with a side opening, a shielding plate is slid into the side opening, and a locking latch is provided between the shielding plate and the side opening.

[0011] Compared with the prior art, the utility model can rely on the locking holes on the left platform and the right platform on the pressure equalizing ring to further assemble the pressure equalizing ring. Screws can be inserted into the locking holes, which meets the assembly needs between the pressure equalizing ring and other equipment. At the same time, an anti-penetration inner cover is provided inside the pressure equalizing ring. The use of the anti-penetration inner cover can greatly enhance the internal anti-penetration ability of the pressure equalizing ring, thereby further enhancing the overall anti-penetration ability of the pressure equalizing ring.
