Dry-type roll iron core transformer

Abstract

The invention discloses a dry-type roll iron core transformer, relates to the technical field of transformers, and solves the problems that the bottom of a currently used transformer is of a fixed structure, does not have a quick extending structure and cannot quickly draw out and check a transformer core assembly. The dry-type roll iron core transformer comprises a base, ventilation frames are integrally arranged at the tops of the two sides of the base; two sets of side plates are fixedly arranged at the top of the base, rotating plates are fixedly arranged at the tops and sides of the rearsides of the two sets of side plates, vertical plates are fixedly arranged on the front sides of the two sets of side plates, a sliding function is provided for the transformer by arranging a slidingframe, and a transformer set can quickly slide on the inner side of the sliding frame in cooperation with sliding wheels. A fixing device can be used for quick fixing, when maintenance is needed, thefixing device can be opened to quickly pull out the transformer set towards the front side, the transformer is quickly overhauled, the operation is convenient, and the maintenance and application of the transformer are facilitated.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a dry-type wound core transformer. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. Transformer is an important equipment in power generation, power supply and power consumption enterprises. It is also in a very critical position in the power grid. It is an important device to ensure the safe and reliable operation of the power grid and the electrodes used by people in production and life. [0003] After retrieval, for example, the patent No. CN106710828B discloses a three-dimensional wound core resin insulated dry-type transformer, including a transformer body, the transformer body includes a three-dimensional wound core, and the three-dimensional wound core includes three...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a dry-type wound core transformer to solve the problem that the bottom of the currently used transformer proposed in the above background technology is a fixed structure, which does not have a rapid extension structure, and the transformer core assembly cannot be quickly pulled out for inspection. It is not conducive to the rapid maintenance of the transformer. At the same time, the general transformer is mainly cooled by air cooling, the cooling speed is slow, and the cooling efficiency is low.
