Abstract

The invention relates to the electric power production auxiliary equipment technology field and especially relates to a power distribution network SYG copper and aluminum transition equipment wire clamp. The wire clamp comprises a first connection component connected to a substation bus downlead and two groups of second connection components connected to electrical equipment. The two groups of second connection components are symmetrically arranged on two sides of a center line of the first connection component. A clamping component is tightly contacted with an external surface of each second connection component. In the invention, through setting two screws with opposite spiral directions, and through rotation of the screws, a distance between the two groups of the second connection components is adjusted so as to adapt to outgoing line terminals with different models; through cooperation setting of a clamping setting component and the second connection components, a line fault caused by shedding between the second connection components and the outgoing line terminals can be avoided; and through setting the clamping component which is tightly contacted with each second connection component, a contact area between the transition equipment wire clamp and the outgoing line terminals of electrical equipment is increased, a transition resistance is reduced and an influence of a construction technology to a transition resistor is decreased so that a problem of a defect fault caused by heating is solved.

Description

technical field [0001] The present invention relates to the technical field of electric power production auxiliary equipment, and more specifically, relates to a wire clamp for SYG copper-aluminum transition equipment in a power distribution network. Background technique [0002] Equipment clamps are mainly used to connect the down conductors of substation busbars with the outlet terminals of electrical equipment such as transformers, circuit breakers, isolating switches, and transformers. Because the outlet terminals of commonly used electrical equipment are copper and aluminum, and the bus lead-out wires are divided into aluminum leg wires or steel-cored aluminum stranded wires, the equipment clamps are divided into aluminum equipment clamps and copper-aluminum transition equipment in terms of material. There are two series of wire clips. [0003] Copper-aluminum transition connection is one of the frequent failure factors of power equipment. Traditional copper-aluminum t...
