A D-type lead wire fixing and clamping device and method

Abstract

The invention provides a D-shaped lead wire fixing and clamping device and method which has a large number of fixed wires and does not change the installation direction of the wires. One of the D-type lead wire fixing and clamping devices includes a first wire clamp assembly, a second wire clamp assembly and a bracket; the first wire clamp assembly is a rectangular frame with an open length side, and the second wire clamp assembly is a linear frame. The second wire clamp assembly cooperates with the length side of the opening of the first wire clamp assembly to form a closed frame, and the wire is clamped in the closed frame; the width side of the first wire clamp assembly is fixed on one end of the bracket in parallel. One of the lead wire fixing and clamping methods includes the following steps: fixing the bracket through the threaded through hole at the fixed end; In the first wire clamp assembly, the second wire clamp assembly is finally fixed to the first wire clamp assembly to realize the arrangement and fixation of the wires.

Description

technical field [0001] The invention relates to a lead wire structure of a large-capacity oil-immersed transformer, in particular to a D-shaped lead wire fixing and clamping device and method. Background technique [0002] With the continuous development of ultra-high voltage and large-capacity transformer technology in my country, the capacity of transformers continues to increase, and the current in the transformer leads continues to increase, resulting in an increase in the cross-section of wires used to connect the transformer coil terminals and the external transformer. As a wire clamp for clamping and fixing the lead wires, the clamping and fixing structure adopted in the prior art cannot meet the ever-increasing weight of the lead wires while not affecting the internal space of the transformer. In the prior art, the wire clamping and fixing structure such as figure 1 As shown, it consists of wire clamp 5 and clamp hoop 6, which are fastened and installed by insulatin...

Problems solved by technology

When using this structure, when the lead wire is bent from the horizontal direction to the longitudinal direction through the wire clamp, the wire needs to be cross-transposed once, and the order of the wire arrangement needs to be changed from two rows and three columns to three rows and two columns. Due to the intersection of the wires, the local arrangement size of the folds becomes larger, and the wires are arranged irregularly; and because the wire clamp 5 is provided with grooves, on the one hand, its strength is reduced, making it unable to bear large weight and a large number of wire structures. On the one hand, it also brings inconvenience to the processing; the clamp hoop 6 matched with it has low structural strength, and the fixing and clamping effect is poor
