A split wire clamp fitting and its branch clamp

Abstract

The invention provides a split wire wire clip fitting and its branch wire clip. The wire clip fitting includes a busbar clip, one end of the busbar clip extending axially along the busbar hole is fixed with a branch wire clip, and each branch wire clip includes a finger-shaped support body and a pressure The clamping block, the finger-shaped support body has an axial installation section extending axially along the branch hole and a radial installation section extending radially along the branch hole which is integrally provided or separately fixed on the busbar clamp, and the clamping block is located in the finger. The inner side of the bending structure formed by the axial installation section and the radial installation section on the shape support body is fixed on the axial installation section, and the opposite sides of the axial installation section and the pressing block are provided with a structure formed by the bending structure. The branch groove of the branch hole, the axial installation section and the radial installation section of the finger-shaped support body are transitionally connected by the arc transition connecting section, and the pressing blocks on each branch clamp are located at the center of the corresponding branch clamp toward the bus hole. inside of the axis. The wire clip fittings have a simple structure, are easy to install and use, and have good anti-corona performance.

Description

technical field [0001] The invention relates to a split wire clip fitting and a branch clip thereof. Background technique [0002] At present, most of the equipment clamps for AC substations put into operation in my country are two-split and four-split wire equipment clamps, while the rated capacity and rated current delivered by DC UHV converter stations are relatively large, and six-split wire equipment clamps are required to meet the requirements. Requirements for UHV DC converter stations. [0003] In the Chinese utility model patent specification whose authorized announcement number is CN203039122U, a wire connection fitting is disclosed, which is used to conduct the corresponding conduction between the pipe busbar and each branch wire. For the busbar hole of the busbar, four branch clamps uniformly distributed around the circumference are arranged on the end of the busbar clamp extending along the axial direction of the busbar hole, and each branch clamp is provided wi...
