Problems solved by technology

The disadvantage is that although the finger-shaped support body is detachably connected with the busbar clamp, the direct contact between the busbar clamp and the pipe busbar is easy to cause mechanical wear, and it is easy to generate eddy current flux ring, resulting in magnetic loss

Embodiment 1

[0036] Combined with the manual figure 1 — image 3 , the present invention is a pipe busbar split wire clamp, including a pipe busbar clamp sleeved on the surface of the tubular busbar 1 and a plurality of flexible wire clamps for splitting wires arranged on one side of the pipe busbar clamp. The busbar clamp includes a first pipe busbar clamp 3 and a second pipe busbar clamp 4 that are symmetrically connected by fastening bolts 2 at both ends. The first pipe busbar clamp 3 and the second pipe busbar clamp 4 are equipped with reinforcement devices, so The reinforcement device includes a gas-generating chamber 5 filled with ammonium bicarbonate, an airbag 6 placed on the top of the gas-generating chamber 5, and a temperature control structure located at the bottom of the gas-generating chamber 5. The gas-generating chamber 5 is respectively embedded in The first pipe bus clamp 3 and the second pipe bus clamp 4 are inside and surround the outer circumference of the tubular bus...

Embodiment 2

[0040] Combined with the manual figure 1 — Figure 4 , except that the number of flexible wire clamps is set to three, and the tubular busbar 1 is vertically connected with the tubular busbar clamps, the others are the same as in the first embodiment.

Abstract

The invention discloses a tube bus split wire clip. The device belongs to the technical field of electric fittings, and solves the problems of weak gripping force, large magnetic loss and poor corona resistance of a tube bus wire clip in the prior art. The tube bus split wire clip comprises a tube bus clip and a number of flexible wire clips. The tube bus clip comprises first and second tube bus clips. Reinforcement devices are arranged in first and second tube bus clips. According to invention, the reinforcement devices are arranged to improves the contact and gripping force of the wire clip and avoid mechanical loss caused by mechanical friction produced by the contact of two parts; an eddy current flux ring is effectively blocked by the reinforcement devices, which avoids magnetic loss; and a support body and a compaction block are in arc transition, which prevents point discharge, and ensures the anti-corona performance of the whole wire clip.

Description

technical field [0001] The invention belongs to the technical field of electric power fittings, and in particular relates to a pipe busbar split conductor clamp. Background technique [0002] At present, the current and voltage of UHV power transmission and transformation projects are relatively high, and the vertical multi-split line clamp fittings of the tube busbar are prone to corona and noise, which endangers the safe operation of the line. Therefore, the design of the fittings must not only ensure the current carrying capacity, but also Ensure good contact and grip of the clip. The existing Chinese patent database discloses a patent for a pipe-busbar split wire clamp fitting, its patent application number is 201420747334.0, and its structure includes: a busbar clamp with a busbar hole, and there are at least two busbar clamps for installation. A branch clamp for a split branch wire, the branch clamp includes an L-shaped finger-shaped support body and a compression blo...
