A kind of New single-phase water-cooled transformer
Technical field
The utility model is related to transformer technology field, more particularly to a kind of New single-phase water-cooled transformer.
Background technology
Single-phase transformer in the power electronic system applied currently on the market plays the works such as transformation, isolation in systems
With the natural air cooled structure of generally use.Vent passages are reserved between this structural requirement coil inside and coil and iron core, and it is logical to divulge information
Road, which will lean against in processing procedure, is put into insulating stay to support, does so and there is following disadvantage:
1. artificial and equipment cost is high, to add insulating stay to do vent passages in coiling, be required for shutting down every time and spend
It is time-consuming;
2. material cost increases, insulating stay belongs to insulating materials, increases insulating stay and is increased by insulating materials cost.
3. small product size is big, since insulating stay thickness generally all (is unable to greatly shape not less than 6mm less than 6mm air drag
At convection current), so interiors of products increases a vent passages and increases a size (6mm or more).
4. the whole temperature of product rises lack of homogeneity, due to the width of Wen Shengyu vent passages, length and depth in vent passages
There are relationship, each vent passages size can not possibly be just the same, so the temperature of each vent passages is also different, general temperature
Difference is at 10-30 DEG C.
5. product weatherability is poor, since product needs wind to recycle, extraneous salt fog and dust can all be accumulated on product, into
And product heat dissipation and etching insulative material are influenced, so as to shorten life of product.
