A kind of transformer novel solid rewinding material

Technical field

The utility model relates to field transformers, and in particular to a kind of transformer novel solid rewinding material.

Background technique

Three dimensional wound core transformer is a kind of Power-saving-type Power Transformer, it has creatively reformed traditional power transformer Laminated magnetic line structure and three-phase layout, optimize properties of product more, rewinding material is divided into plane wound core and three-dimensional winding iron There is very big difference in the heart, the two.

China started to develop the transformer of stereochemical structure in the 1960s, such as evolvent type iron core, three-dimensional laminated core Deng the reason of being limited to material and technology, to late 1990s, domestic some producers just develop reasonable three-dimensional winding Iron-core transformer, after 2003, Wound iron-core transformer just gradually obtains the approval of user, obtains some applications.

The existing three dimensional wound core transformer production producer for forming certain production capacity in the whole nation is few, is limited to technology original Cause, the production of three dimensional wound core transformer are concentrated mainly on 10kV315kVA or less oil immersion-type distribution transformer, are mainly used in Upgrading of rural power grids project.

What the country took the lead in producing dry type three dimensional wound core transformer in batches is the Jiangxi three-dimensional Electric Applicance Co., Ltd of rich electricity (existing name For JiangXi Han's Power Technology Co., Ltd.), produce dry three dimensional wound core transformer in batches since 2003.

Three dimensional wound core transformer is a kind of Power-saving-type Power Transformer, it has creatively reformed traditional power transformer Laminated magnetic line structure and three-phase layout, optimize properties of product more, as three-phase magnetic circuit is full symmetric, power savings are aobvious It writes, noise substantially reduces, radiate and overload capacity is stronger, compact-sized etc..

Structure is complicated for transformer three dimensional wound core currently on the market, and production cost is higher, and stability is poor.
