FURNACE TRANSFORMER

Main functions and characters 35kV arc furnace transformer technical parameters

110kV/66kV/35kV Main Functions and Features:

Electric furnace transformers are transformers which supply power to the electric furnaces. It can drop high voltage to the working voltage the electric furnaces need.

There are many kinds of electric furnaces,so there are many kinds of electric furnace transformers cooperating with them.Now,our company manufactures following electric furnace transformers:electric furnace transformers used in steelelectric furnaces(including on-laod, no-load and enclosed reactor) ; mineral hot furnace transformers used to smelt kinds of iron alloys, hydrosilicons, carbides,etc(single phase, three phases on-load and no-load tap changer).They are low loss and energy-saving products.Cooling methods are self-cooling, forced oil water cooling, etc.It can be designed specially according with customers’ requirements.

The model of the electric furnace transformer is expressed as follows: Application

Number of Phases

Cooling Type

Type of Oil Circulation

The meaning of model:

Type of Taping

H--Steelmaking arc furnace, HJ--ladle furnace, HZ--electro-slag furnace, HC--calcium carbide furnace, HK--mineral hot furnace, HG--line frequency induction furnace;

Number of phase:

D--single phase, S--three phase;

Types of cooling device:

ONAN, wind cooling F, water cooling S.

The methods of oil circulation:

Low loss: No-load losses is about 40% lower than that required in current national standard GB6451-1999; load losses is about 15% lower than that required in current national standard GB6451-1999; Low noise level: <60dB, about 20dB lower than that required in the national standard; Low partial discharge: the full range process of 220kV product is dust-free operation; metal parts and insulation parts inside the transformer are all rounded; the partial discharge is controlled to be lower than 70pc; High short-circuit capacity: the independently designed SFP10-200000/220 transformer of the Company has passed the short-circuit test of the National Transformer Quality Test & Inspection Center (CTQC) (CTQC); Beautiful appearance: oil tank bending corrugated structure, shot blasting de-dusting, powder EFI paint, wide fin radiator, never fade in color; No leakage: all seal with limit position and upper & lower tank edges are sealed along two channels; sealing gasket is imported. We solemnly commit no leakage of oil.

2.2 The insulation power field intensity between turns shall be controlled no greater than 1.6kV/mm.

3. Body

3.1 Body adopts mature insulation structure, and strictly guarantee the main axial insulation margin.

3.2 Body mostly adopt multi-coil whole assembly, processed in constant voltage and evaporation, which made coil shrink evenly and with less rebounce, and enhance the electric strength and mechanical strength.

3.3 Adopt laminating wood board or thermal shaped insulation cardboard. Pressed tightly with pin, which ensure the winding is constantly pressed tightly.

4. Leading wire

4.1 The layout of all leading wire is reasonable, which guarantees the enough electric distance and mechanical strenth.

4.2 All leading wire is cirlulized ,which guarantee the reliable wild or prize connection.

5. Oil tank

5.1 Oil tank adopts structure of flat top, bell jar type, which add the mechanical strength of oil tank and also make the appearance beautiful and graceful, site installation tend to be more convenient.

5.2 Pipeline with gas relay such as the oil tube and bushing hoist support on top of oil tank is with hoist gradient, to facilitate the gas in transformer flow to gas relay.

5.3 Vacuum oiling is adopted, there is no leakage and permanent distortion in the following test. vacuum-pumping: 759mmHg load voltage test:

bear 2 times the oil pressure of oil conservator oil surface for 24 hours.

5.4 The structure of transformer is convenient for disassembly and change of bushing and porcelain element.

5.5 The oil drip valve is set on the bottom of oil tank, sampling valve is set in the middle.

5.6 collective gas connecting tube is fixed on the bushing hoist support.

5.7 Transformer is of full-sealed structure, the upper and down oil tanks are required to welded fully.

OIL-IMMERSED POWER TRANSFORMERS

110kV

6. Oil conservation tank

6.1 Adopt capsule type, finger type oil level indicator oil conservation tank.

6.2 The structure is convenient for internal cleaning, the capacity can ensure no oil overflow in 40oC ambient temperature with full load, and oil shall be seen from oil level indicator before put into operation in -25oC. 6.3 Oil conservation tank is equipped with oilsealed moisture absorber.

7. Safety protection device:

7.1 Gas relay is fixed in transformer, the standard complies with ZBK41004-89<Gas relay>.

7.2 There is enough and reliable pressure release device, and matched with oil spray pipe, the direction of oil spraying is downward.

8. Oil temperature measuring device:

8.1 There is pipe support of mercury thermometer, which is set on the top of oil tank.

8.2 There is temperature controller, the accuracy of thermometer complies with the related standard.

Quantity and technical requirement shall as per tender document.

9. Each component of transformer shall be prefabricated once in manufacture factory, marked, to ensure the smooth procedure of site assembly.

Before Ex-factory, inner core shall be check, and clean the fifth in transformer.

Main functions and characters It adopts advanced electromagnetic design software, and meets IEC60076, GB1094, GB/ T6451, GB/T25289-2010 standards. Without such device like conservator, air breather..., so it ensures that the transformer oil is not in contact with air, improving the anti-oxidation capacity of the transformer oil and delaying its aging. The core is made of high quality cold-rolled grain-oriented sillcom steel sheet, with laminated structure miter joint, so as to reduce the no-load losses and noload current. The tank is a corrugated type, the corrugated fins can swell and shrink with the change of transformer oil, so that the pressure

● Without such device like conservator and air breather, it ensures that the transformer oil is not in contact with air. So commonly, the transformers can be used continuously for 20 years without any particular treatment. ● Excellent rubber is adopted in the sealing parts. ● Vacuum oil-filling process is used.

SINGLE PHASE POLE MOUNTED DISTRIBUTION TRANSFORMER

Product model: DH15-M or D11-M Rated Voltage:10kV/(0.22~0.24) or 2×(0.22~0.24) kV (or the voltage proposed by the user) Tapping range: ±5%; ±2*2.5% Frequency: 50Hz Vector group: II0 or II6 Operation environment: outdoor In order to meet the various demands of customers, the Company has design D11-M and DH15-M two series single phase fully-sealed transformer.

D11-M transformer adopts laminated core and is characterized by low loss, low noise level and others; DH15-M transformer adopts amorphous alloy core which further reduces the no-load losses of the transformer. Table below specifies technical parameters and dimensions of the two series of transformers.

Top: ventilation holes have effective rain-proof and water-proof capabilities; Side: carry out surface treatment for sides by waterproof concrete materials so that water can not penetrate from sides; Bottom: install waterproof concrete bearing base for buried transformer that is 300mm higher than the pit bottom.

At usual time, water flowing from the ground into the pit will enter the ring channel under the base so that it will not immerse the buried transformer.

Lay sandy cobble at the bottom of the base so that water can penetrate into the ground more quickly.

Buried type transformer can also operate when immersing in water for more than 0.5m for a certain period of time. It can withstand floods and can effectively improve the reliability of the power supply system.

However, in order to ensure the safe and reliable operation of the transformer, it is suggested to check the water accumulation situation in the pit after floods and long time heavy rainfall and the rainy season.

If there is too much water, pumping and cleaning should be carried out.
