Abstract

The invention provides a copper-aluminum transition clamp, which relates to the technical field of electric power transmission and solves the existing problems that aluminum wires are prone to oxidation when used for a long time, which reduces the transmission quality of aluminum wires and is prone to power outages in severe cases. It includes a conductive device; the top of the conductive device is equipped with a wire fixing mechanism and an automatic locking assembly, and the automatic locking assembly is located on the left side of the wire fixing mechanism, and the bottom of the automatic locking assembly is equipped with a connecting assembly, and is automatically locked The right side of the assembly is equipped with a fixing device; the driving mechanism, after the aluminum wire is fixed in the present invention, the top of the sealing block is closely attached to the outer wall of the aluminum wire, thereby preventing oxygen from entering the inner side of the sealing block, and because the aluminum wire is fixed, contact The block is inserted and connected in the aluminum wire, thereby reducing the oxidation of the aluminum wire, ensuring the conductive accuracy of the aluminum wire, and ensuring the normal transmission of power.

Description

technical field [0001] The invention belongs to the technical field of power transmission, and more specifically relates to a copper-aluminum transition clamp. Background technique [0002] Copper and aluminum belong to different elements. The metal inertness of copper is greater than that of aluminum, that is, the chemical activity of copper is much lower than that of aluminum. In this way, after the two metals are connected, an electrochemical reaction will occur, which will cause the aluminum wire to be gradually oxidized and reduce the aluminum. The mechanical strength and electrical conductivity of the wire; therefore, both copper and aluminum wires are connected with copper-aluminum transition clamps. [0003] Based on the above, the inventors found that the current copper-aluminum transition clamps, the contact positions of the copper body and the aluminum body are fixed by welding, which is prone to breakage when oxidized or pulled by external force, and the service ...
