Three-dimensional wound iron core three-phase dry-type transformer for nuclear station

Abstract

The invention discloses a three-dimensional wound iron core three-phase dry-type transformer for a nuclear station. The transformer comprises a supporting frame as well as clamp pieces, three-dimensional wound iron cores and coils, which form a transformer main body, wherein the three-dimensional wound iron cores are arranged in triangular shapes and wound with the coils respectively to form three-phase structures; the clamp pieces comprise upper clamp pieces and lower clamp pieces; the triangular structures of the three-dimensional wound iron cores are fixed with the lead wires of the coils through the upper clamp pieces and the lower clamp pieces; the supporting frame comprises a frame base and an anti-seismic bracket; the transformer main body is mounted and fixed on the frame base; the anti-seismic bracket is arranged between the transformer main body and the frame base. The anti-seismic bracket is configured on the basis of the three-dimensional triangular structure, is also of the triangular structure and is used for supporting the three side surfaces of the transformer main body, so that the whole transformer can be kept stable when being stressed in different directions, the anti-seismic capability of the transformer is greatly improved, and the safety level of the transformer is higher.

Description

technical field [0001] The invention relates to a transformer support, in particular to a three-dimensional wound core three-phase dry-type transformer for nuclear power plants. Background technique [0002] With the maturity of power generation technology, various new energy power generation has gradually developed, and transformer products have gradually been applied to various fields, such as solar photovoltaic power generation, nuclear power, etc. As a new generation of clean products, nuclear power provides powerful energy support for the development of modern industry. However, if not handled properly, nuclear power products are like time bombs hidden around us, which may endanger our safety at any time. Therefore, higher requirements have been placed on the anti-seismic aspects of transformer products used in nuclear power plants, and traditional transformer supports cannot withstand high-intensity vibrations. Contents of the invention [0003] In order to solve t...
