Description

Technical Field

[0001] This invention relates to the field of equalizing ring technology, and in particular to a detachable equalizing ring. Background Technology

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

[0003] In existing technology, when installing an equalizing ring, the notched ring is first passed through the insulator and then fixed on the insulator. The notch cannot effectively prevent side lightning strikes. After the equalizing ring is fixed, workers usually need to weld an arc-shaped rod to seal the notched ring, which is very troublesome to install. Therefore, we propose a detachable equalizing ring. Summary of the Invention

[0004] To address the problem that when installing an equalizing ring, the notched ring must first pass through the insulator and then be fixed onto the insulator, resulting in poor protection against side lightning strikes at the notch and a very cumbersome installation process, the purpose of this invention is to provide a detachable equalizing ring.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a detachable equalizing ring, comprising a notched ring, the notch of which is used to pass through insulators, cables, etc., for installation; a detachable arc-shaped supplementary rod is installed at the notch of the notched ring, so that the detachable equalizing ring can effectively prevent side lightning strikes around its entire circumference; a clamping mechanism is installed on the inner wall of the arc-shaped supplementary rod for clamping and fixing the detachable equalizing ring; two symmetrically arranged protrusions are fixedly provided on the inner wall of the notched ring, the side of the protrusion away from the ring body is flat, and a detachable connecting beam is installed between the two protrusions, the two ends of which can be completely fitted with the flat surfaces of the two protrusions.

[0006] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0007] 1. In this invention, the notch in the notched ring is used to pass through insulators, cables, etc., for installation;

[0008] 2. In this invention, the connection and disassembly of the arc-shaped supplementary rod and the notched ring are very convenient, and the arc-shaped supplementary rod and the notched ring form a completely closed ring, so that the detachable equalizing ring can effectively prevent side lightning strikes all around.

[0009] 3. In this invention, the connection and disassembly of the connecting beam and the notched ring are very convenient, and the cooperation between the connecting beam and the clamping mechanism makes it easy to clamp and disassemble the detachable pressure equalizing ring.

The two sides of the clamping block 301 are fixedly connected with guide strips 305 that slide in cooperation with the two sliding grooves 503. An arc-shaped clamping groove is opened on the side of the clamping block 301 facing the bottom of the mounting groove 502.

[0027] The connecting beam 5 has two grooves 505 at both ends that slide with the outer walls of the two positioning blocks 501. The side wall of the connecting beam 5 has a rectangular hole 506 communicating with the grooves 505. A second spring 507 that abuts against the positioning block 501 is fixedly installed inside the groove 505. A second lever 504 is fixedly connected to the side wall of the positioning block 501.
