Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] Such as image 3 , Figure 4 Shown is a lap-joint copper-aluminum transition clamp, which includes an equipment clamp 1 connected to the equipment wiring board 4 and a wire clamp 2 connected to the wire 6, the equipment clamp 1 and the wire clamp 2 There is an overlapping transition between them, and they are welded and fixed by brazing; the overlapping parts between the equipment clamping part 1 and the wire clamping part 2 are all square-shaped. When in use, the equipment wiring board 4 and the equipment clamping part 1 It is mechanically fixed with the wire clamp 2 by a fastener 5 .

[0020] Compared figure 1 , figure 2 , the traditional transition interface 3 is only the end face, while image 3 , Figure 4 The transition interface 3 is the entire upper side of the device holder 1, and the area is increased by 5 to 7 times.

[0021] The above is only...

Abstract

The invention discloses a lap-joint type copper-aluminum transition wire clip, which comprises an apparatus clamping part and a lead wire clamping part. The apparatus clamping part and the lead wire clamping part are transited through lap joint, and fixed by welding. The copper-aluminum transition wire clip provided by the invention has the characteristics of simple structure and convenient application. The lap-joint structure substitutes for the conventional butt-joint structure, which effectively increases a copper-aluminum transition area, reduces a transition resistance, and alleviates heat generating phenomenon. Meanwhile, the stress of the wire clip during application is changed, and the mechanical strength of the wire clip is improved. By the adoption of the advanced brazing technique, the welding quality is improved.

Description

technical field [0001] The invention relates to a clamp for fixedly connecting wires and other primary equipment (such as a disconnector), in particular to a lap-joint copper-aluminum transition clamp. Background technique [0002] Wire clamp is one of the very common components in the primary equipment of the power grid, mainly responsible for fixing the connecting wire and other primary equipment (such as isolating switch). The currently used clamps mainly include copper-aluminum butt joint clamps and pure aluminum / copper wire clamps; due to the disadvantages of high transition resistance and easy overheating of pure aluminum / copper wire clamps compared with copper-aluminum butt joint clamps, the scope of use is relatively small, and most Copper-aluminum butt clamps are used. The general structure of the copper-aluminum butt joint clamp is as follows: figure 1 , figure 2 As shown, it mainly includes the equipment clamping part 1 connected to the equipment wiring board ...
