Transformer oil gap experimental measuring device enabling precise adjustment

Abstract

The invention relates to a transformer oil gap experimental measuring device enabling precise adjustment. The device comprises a box body; a high-voltage plate with a tungsten-copper thread electrodeis arranged in the box body; a measuring plate and protection plates with plugging slots are arranged in the box body; a plurality of epoxy stays are fixedly arranged on the high-voltage plate; a fastening ring and a washer are arranged at the middle of each stay, so that the edges of test sample insulation paper can be attached to each other closely; the epoxy stays are located between the high-voltage plate and the measuring plate through the plugging slots in the protection plate; the test sample insulation paper is fixed on the measuring plate; a protection plate bottom column and a measuring plate supporting column are arranged at the lower parts of the protection plate and the measuring plate respectively; and the grooved supporting column of the protection plate and the grooved supporting column of the measuring plate are respectively connected with a protection plate lead-out end column and a measuring plate lead-out end column through wires. The transformer oil gap experimental measuring device enabling precise adjustment of the invention is easy to use, can realize precise adjustment and is easy to disassemble and clean. With the device adopted, transformer oil gap experimental parameters can be accurately determined.

Description

technical field [0001] The invention relates to the technical field of high-voltage insulation, in particular to a measuring device capable of precisely adjusting transformer oil gap experiments. Background technique [0002] my country's power industry is in a rapid development stage. With the development of ultra-high voltage transmission technology in China, oil-immersed transformers have become one of the very important equipment in the power grid. If the transformer fails, it will affect the normal operation of the entire power grid, and may even cause the collapse of the power grid, causing serious economic losses or personal safety to the country, enterprises, and residential users. Most of the damage and failures of oil-immersed transformers are caused by the aging of the insulation system. With the increase of the operating life of the transformer, affected by factors such as temperature, moisture, and machinery, aging products such as CO, CO2, and furfural will be ...

Problems solved by technology

[0004] Considering that the operation of the existing transformer oil-paper characteristic testing device is complicated, the edge of the insulating paper of the test product cannot be closely attached during the measurement, resulting in the inclusion of air bubbles between the papers, and the sliding between the test papers caused by the oil filling and the placement of the high-voltage pole plate will offset the measurement pole. board, it is difficult to carry out the oil gap simulation experiment and the oil gap data is inconvenient to read, the oil change experiment operation is too cumbersome, and the shortcomings and deficiencies of the large experimental error
