Paper insulation winding wire and paper covered transposed lead short circuit detection restoration method and device thereof

Abstract

The invention relates to a paper insulation winding wire and paper covered transposed lead short circuit detection restoration method and a device thereof, belonging to the transformer manufacture special-purpose detection restoration technology field. A technical scheme of the invention is as follows: a detected paper insulation winding wire and paper covered transposed lead is placed on a line laying rack, a line coiling rack and a lead support, the line laying rack and the line coiling rack is controlled through a control board, bidirectional winding the paper insulation winding wire and paper covered transposed lead is realized, and a short circuit point is searched on a thread spool. According to the method and the device in the invention, a short circuit restoration speed of the paper insulation winding wire and paper covered transposed lead is raised, positioning is accurate and rapid, transposed lead restoration problems of jumping wire, drilling wire, lacking a paper layer the like appeared in the transposed lead can be restored simultaneously, usage capability of the device can be raised to greatest extent, elimination and restoration of various faults existed in varioustransposed leads are accelerated, an operation is simple, usage is convenient, various short circuit problems of various function transposed leads can be rapidly and thoroughly eliminated, and a product qualified rate of the transposed leads is greatly raised.

Description

technical field [0001] The invention relates to a short-circuit detection and repair method for paper-insulated winding wires and paper-wrapped transposition wires, and belongs to the technical field of detection and repair for transformer manufacturing. Background technique [0002] At present, in the production process of paper insulated winding wires and paper-wrapped transposed wires, due to various reasons, such as burrs of copper conductors, damage of paint film, welding copper powder and other reasons, short circuit faults of wires often occur. How to quickly and accurately find the location of the short-circuit point is very important. Manufacturers have always used meggers and electric bridges to measure the resistance between two short-circuit lines, and determined the location of the short-circuit point through calculation. This method requires that the short-circuit resistance of the short-circuit point be zero to calculate the accurate position. Otherwise, the...

AI Technical Summary

Problems solved by technology

Otherwise, the calculated value will have a large error, and it is impossible to accurately find the short-circuit point of the wire

And sometimes due to the small resistance value of the short circuit point, errors will occur, and the repair will increase the repair time due to the long opening of the insulation, which will increase the labor intensity of the repair personnel and reduce the production efficiency.
