Insulated wire withstand voltage test method and test tool thereof

Abstract

The invention discloses an insulated wire withstand voltage test method and a test tool thereof, and relates to the technical field of insulating layer breakdown voltage test. An insulated wire sample is folded and twisted into a twisted wire pair, then the insulated wire sample is tightly wound on a conductive column, insulating layers at the two ends of the insulated wire sample are removed to make conductor sections exposed out of the ends of the insulated wire sample, and test voltage is applied to the conductor sections and the conductive column of the insulated wire sample so as to measure the voltage resistance and value of the insulating layer of the insulated wire sample. The twisted insulated wire sample is wound on the conductive column, so that the wire rod is more compact, personal errors are reduced, and the test effectiveness and reliability are improved. The insulated wire withstand voltage test tool is used for implementing the method, the conductive column is erected on the first positioning piece and the second positioning piece, and the first conductive body and the second conductive body are electrically connected with the conductive column and the insulated wire sample, so that the test efficiency is improved and the operation process in the test process is simplified on the premise of improving the effectiveness of the test result.

Description

Technical field [0001] The present invention relates to the field of insulating layers, and more particularly to an insulated line withstand voltage test method and a test tool. Background technique [0002] Wire and cable is widely used in electricity, construction, communication, manufacturing and other industries, closely related to the various departments of the national economy; "arteries" and "nerves" called the national economy, is transported, transmitting information, and manufacturing various kinds. Motors, instruments, meters, indispensable basic equipment in electromagnetic energy conversion, is the necessary basic products necessary in the future electrification and information society. [0003] With the development of electrons, electrical technology, the standards and the quality of the desired insulation lines are required in each product are also constantly changing. In order to adapt to its changes, the requirements for the coating continuity of the insulating l...

AI Technical Summary

Problems solved by technology

[0004] In the existing wire withstand voltage test method, because the wire is affected by its processing technology and cross-sectional shape, the defective parts in the existing test method may be missed or the test value is inaccurate, and the error is artificially introduced. Relatively large, the validity of the test results is low
