An electrical connection method and connection device for a high-voltage equipment wire and a metal inner cylinder

Abstract

The invention relates to an electric connection method and device for a high-voltage equipment wire and a metal inner cylinder and aims to solve the problem that existing high-voltage equipment is unreliable in electric connection, poor in connection strength and prone to falling off and the problem that an existing electric connection device cannot be suitable for electric connection between a high-voltage equipment wire and a large-area metal connection layer. The method of the invention comprises the steps that: 1, an inner barrel conical through hole is formed in a high-pressure equipmentinner barrel, wherein the high-pressure equipment inner barrel comprises a first inner barrel body and a second inner barrel body; 2, a hollow conductive column is processed, and a wire is fixed in the central hole of the hollow conductive column; 3, the hollow conductive column with the wire is inserted into the inner barrel conical through hole; 4, the hollow conductive column is completely fixed on the high-voltage equipment inner barrel by using a nut and a cushion block; and step 5, the electric connection state of the wire and the inner barrel is checked.

Description

technical field [0001] The invention relates to an electrical connection method for high-voltage equipment, in particular to an electrical connection method and a connection device for a high-voltage equipment wire and a metal inner cylinder. Background technique [0002] In some high-voltage equipment, it is generally necessary to realize the electrical connection between the wire and the metal layer with a large area. The existing traditional method is to process blind holes on the metal surface to be welded, and use solder and electric soldering iron to weld the wires in the blind holes on the large-area metal layer. In this way, since the welding between the wire and the large-area metal layer is realized, electrical conduction between the wire and the metal layer can be realized. However, this method has the following defects: the connection between the wire and the metal layer is unreliable, the connection strength is poor, and it is easy to fall off. The layer is qu...
