AI Technical Summary

Technical Problem

The existing fully enclosed transformers with basin-type insulators as the outline type are difficult to meet the insulation distance requirements between charged bodies in the air during actual testing, which can easily lead to detection failure or even accidents.

Method used

A transformer testing tool for basin insulator outlet is designed, including a testing host, a testing table and a testing tool. Through the tool housing, a testing casing and an internal plug-in and unplugged connection conductor, combined with an insulating gas filling and deflation device, it meets the internal and external Insulation requirements ensure sealed and stable connection between the test sleeve and the basin outlet structure.

Benefits of technology

Effective tests of basin insulator outlet transformers are realized, which meets the insulation requirements of high-pressure, low-pressure and neutral points, reduces the cost of use and time, and avoids detection failures and safety hazards caused by the influence of air insulation level.

Abstract

The invention discloses a transformer test tool with a basin-type insulator outgoing line, and particularly relates to the technical field of transformer test, the transformer test tool comprises a detection host and a detection table, a basin outgoing line structure comprises an outgoing line basin, and the outgoing line basin is installed in a corresponding outgoing line base on a to-be-tested transformer; a test detection tool is arranged on the detection host, the test detection tool is composed of a tool shell, a test sleeve and an internal plug-in type connecting conductor, and an inflation and deflation valve seat and a gas pressure gauge are arranged on the tool shell. The basin-type insulator outgoing line transformer test tool meets the requirements of the test output end of the transformer, can be used for standardized design, can be repeatedly used on products of the same voltage class, can meet the requirement of low-voltage end common box outgoing line, is not influenced by the installation time, space and connection structure of a transformer body, and can be widely applied to the field of transformer testing. Therefore, the requirement of air insulation level does not need to be considered when the high-voltage outgoing line is designed for the transformer with the basin-type insulator outgoing line, and the use cost and the time cost are reduced.
