Transformer with split and pluggable iron core for screening test

Abstract

A transformer with a split and pluggable iron core for screening test relates to the field of transformers. Time is wasted and a trouble is brought during plug-in and plug-out of a transformer iron core, and the iron core is easy to damage when the iron core is disassembled and plugged. The transformer comprises iron cores, an excitation coil, a response coil, an insulation support plate, a support rack and a lifting rack, wherein the excitation coil and the response coil sleeve at outer sides of the iron cores, the iron cores are two posts of iron cores formed by lamination of lamination sheets, each iron core comprises an upper iron core and a lower iron core, the lower iron core is in a U shape containing two iron core posts, and the upper iron core is line-shaped and can be connected to the tops of the lower iron cores in a pluggable way. With the transformer disclosed by the technical scheme, the upper iron core can be integratedly plugged in and plugged out, the transformer is simple, convenient and rapid, and is low in plugging influence and high in electrical stability, and the iron core connection quality is still stable and reliable.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a transformer for screening tests with detachable and pluggable iron cores. Background technique [0002] In the manufacturing process of transformers, the test of transformers is a very strict means of checking. In the test and detection of large transformers, sometimes the following problems occur. Remove the problematic coil for processing or in-depth analysis. Removing the coil means removing the upper iron yoke. The upper iron yoke is a piece of silicon steel sheet. Removing the upper iron yoke requires a lot of manpower and working hours. It is the most important part of the transformer. One of the time-consuming processes, this very complicated work sometimes has to be repeated many times to solve the problem, which often affects the production cycle, and the transformer core will directly lead to no-load loss after repeated disassembly and insertion become larger and affect p...
