5.Combined type transformer

Description:

Combined type wind power transformers are the self- developed and self-designed products which to meet the growing wind power generation requirements by digesting and absorbing the advanced technologies combined with domestic demand.

The transformers can withstand shake and bumps in long-distance transportation way, and routine core inspection are not needed when the transformers sent to installation place.

Boxes are adopted the special process, and they have good anti-corrosion ability to effectively prevent wind erosion and coastal salt spray.

ZBW (YB) Series modular substation is combined with high-voltage room, transformer room, low-voltage chamber. It has excellencies such as run a safe, reliable, complete and strong, lower total cost, short installation, operation and maintenance simple, handsome in appearance and so on.

1. Keep low loss

1)．In the design ,we choose high quality, high magnetic orientation cold-rolled silicon steel..

2)．Core design uses 6 step process specific joints (normally 2-5 step process joints of domestic manufacturers).

3)．Iron core applies entire miter joints, ceaselesss joke, no holes no banding.

2. Keep low noise

1)．Constantly optimize the electromagnetic design,choosing high quality high lead magnet cold-rolled silicon steel.

2)．Iron core applies entire miter joints, no stack on the iron yoke technology.

3)．Apply 6 step process specific joints to make the magnetic line of force to be more flat.

4)．The Core tighten use special technology, utilize specially formulated multi-component curing adhesive core of end face.

5)．Iron yoke uses plate clamps, clamps and beam form the frame structure.At the key parts,tight with a special device, so that the whole core is more solid and reliable.

3. Keep low partial discharge

2)．Increase angle ring at the presence of a strong centralized location.

3)．Electrostatic panels turns to be new structure,strictly control the quality of their dressing and welding.

4)．Lead bonding use cold welding wire technology,and L.V lead wire use carbon fine wire welding. 5)．All insulation and metal structure requires rounding chamfer,unhair and smooth handling.

8)．Improve on-site management, the implementation of the closed shop management to effectively reduce the dust amount.

9)．Strict control the quality of raw materials from the source of procurement.

4. Strengthen anti-short circuit capability

1)．First considerate the design of the dynamic thermal stability of the product, establish separate regulating transformers.

2)．Increase the winding shift winding, and its purpose is to improve the efficiency and reduce the input harmonic transformer.

3)．All Winding cardboard pads use Weidmann, pre-unhair, dry, and dense processing, to keep the winding axis height.

4)．The hoardings, stays and other insulation in Transformer body must be pre-dried prior to assemble.

5. Keep strong overload capacity and long service life
1). We strictly control the design of the top oil temperature and winding temperature rise.
2). In the coil design, according to the laws of fluid flow, using the principle of twists and turns driven oil.
3). Chose the reasonable wire gauge, strictly control the wire size.
