36000A strong current generator and detecting method thereof

Abstract

The invention discloses a 36000A strong current generator. The 36000A strong current generator is characterized by comprising an annular iron core, a primary winding, a strong current guide line, a copper pipe and a plurality of connecting copper bars, wherein the primary winding is uniformly wound on the annular iron core; the strong current guide line is uniformly wound on the outmost layer of the primary winding; the copper pipe penetrates through a window of the annular iron core; one end of the copper pipe is connected with one end of the strong current guide line, and the other end of the copper pipe is connected with the connecting copper bars to form a circuit, so that a secondary winding is formed. According to the 36000A strong current generator and a detecting method of the 36000A strong current generator, disclosed by the invention, the problems of heavy weight, complicated wiring and large testing labor intensity of the strong current guide line and generation of larger noise due to vibration of the strong current guide line during a test are solved; through the arrangement of the copper pipe and the copper bars, the wiring is simple, the operation is convenient, the experimental noise is low, the integration degree is high, more safety and reliability are realized, the manpower is reduced, and the field testing time is greatly saved; the 36000A strong current generator and a detecting method of the 36000A strong current generator are successfully applied to a laboratory.

Problems solved by technology

When performing an error test on a 30,000A high-current current transformer, the primary conductor needs to pass a large current of 36,000A, and multiple high-current wires are used as the primary conductor during the step-up process, and the primary conductor needs to pass through the current booster, standard current transformer, and When measuring current transformers, the high-current wires are heavy, the wiring is complicated, the labor intensity of the experiment is high, and the vibration of the high-current wires during the test will generate large noise

[0003] At present, the domestic verification of 30000A current transformers uses the equal-ampere-turn method. The equal-ampere-turn method uses multiple strands of secondary conductors t
