Embodiment Construction

[0025] Examples of wire clamp fittings in the present invention: Figure 1 to Figure 12 As shown, the wire clamp fitting is a kind of UHV DC converter station split wire clamp fitting used for T-connection conversion between four-split conductors and terminal board 5. It is mainly composed of a clamp cover 1, an upper splint 2 and a lower splint. The cover plate is composed of the wire clamp cover plate 1, the upper splint 2 and the lower cover plate are all made of ZL101A cast aluminum silicon alloy, which reduces weight, increases strength, and has high temperature resistance and corrosion resistance.

[0026] The upper clamping plate 2 is an L-shaped plate body formed by integrally connecting the upper plate 21 and the front vertical plate 22. The upper plate 21 is bent backwards at the top of the front vertical plate 22. The upper splint 2 includes upper fixing clip parts provided on the left and right sides. The upper fixing clip part is semi-cylindrical, and the convex surf...

Abstract

The invention discloses a split clamp fitting. Two terminal clamping plates used for oppositely clamping a terminal plate are arranged on a terminal interface of the clamp fitting. The two terminal clamping plates are conductively connected with a wire interface. The opposite lateral plate surfaces of the two terminal clamping plates are provided with conductive contact surfaces which are used for fitting the two lateral plate surfaces of the terminal plate respectively. The two terminal clamping plates are correspondingly provided with fastening holes extending in relative directions. Thus, when the fitting is electrically connected with the terminal plate, the terminal plate is clamped between the two terminal clamping plates, and a diversion function is achieved through wire contact between the conductive contact surfaces on the opposite lateral plate surfaces of the two terminal clamping plates and the two lateral plate surfaces of the terminal plate. Therefore, when bolt connection between the fitting and the terminal plate is loosened, there is always one of the terminal clamping plates closely fitting the terminal plate. The clamp fitting is always in close contact with the terminal plate, the area of conductive contact is increased through conductive contact between the two terminal clamping plates and the terminal plate, and the through-flow performance is further improved.

Description

Technical field [0001] The invention relates to a split wire clamp fitting. Background technique [0002] At present, with the increasing domestic power demand, the capacity and current carrying capacity of conventional converter stations are gradually unable to meet actual needs, and the clamp fittings used in conventional converter stations cannot meet the requirements of new UHV DC converter stations. For example, Chinese Patent Document CN103701078A (published on April 2, 2014) discloses "a wire connection fitting for UHV converter stations", including a flat port for connecting flat terminal boards, The first port for connecting the first wire and the second port for connecting the second wire, wherein one side of the terminal board is attached to the flat port and is fastened by bolt connection; the first port is fixed on The six-claw type first fixed gripper on the flat-plate port, each claw of the first fixed gripper is connected to one of the six-split wires; the second...
