Shandong Fuda Transformer Co., Ltd. is a national high-tech enterprise specializing in the design, production, development and sales of power transformers and their supporting products. The company has established a good internal mechanism, a complete technical research and development force and a mature after-sales service team. The excellent working environment and good incentive mechanism have attracted a number of high-quality, high-level and high-efficiency talents. At present, there are 160 employees, including more than 10 senior engineers, more than 30 intermediate engineers, 5 registered power engineers, and 5 national second-level construction engineers. In addition, the company's grassroots employees have received professional job training, and all teams and departments have experienced technicians, which provides a solid guarantee for the process and quality of products. Since its establishment, the company has been implementing modern management and technology research and development upgrading.

The company passed the strict audit in March 2012 and passed the ISO9001: 2012 quality management system certification; In June 2013, it passed ISO14001 environmental management system certification and occupational health and safety management system certification. Since 2008, many products of the company have passed the type test of the National Transformer Quality Supervision and Inspection Center.

Main products of the company: 35KV, 10KV transformers (can be customized according to customer needs) and other oil-immersed transformers and resin-insulated dry-type transformers; European box transformer, American box transformer, special transformer, photovoltaic box transformer, high and low voltage complete equipment (high voltage cabinet, low voltage cabinet, integrated distribution cabinet, etc. ).

The company always takes science and technology as the guide, maintains close technical cooperation with authoritative power transmission and transformation scientific research institutions at home and abroad, takes full advantage of talents, regions and technology, constantly introduces internationally advanced power equipment manufacturing technology, and insists on independent innovation. With the expansion of scale, the company has actively explored overseas markets and exported its products to Africa, Canada, India, Cambodia, Vietnam, Laos, Kyrgyzstan, Chile, Brazil, Iran, Pakistan and other countries, striving to build its own international brand image.

Shandong Fujie Import and Export Co., Ltd., a subsidiary of the company, is mainly engaged in import and export trade.

Product Description

Load capacity regulating power transfommer produced by us is a new type energy saving distribution transformer, theproduct has two kinds of rated capacity, the principle is that in the case of uninterrupted power supply, the transformetreck the load changers through the intelligent system, automatically change its capacity according to the size ofelectnical load.lt solves the problem that seasonal load variation of 10kV distribution network which cause high lossof transfomer, and overcomes the problem that off-load capacity regulating power transformer is manually adjustedcapacity under outage conditions to cause difficult operation and maintenance.

Product features

After automatically capacity regulating, transformer will be run at reasonable situation.

Through capacity regulating, no-load loss of transformer is comprehensively reduced by 50%-70%, reactive powerloss of grid is reduced by more than 20%, and reactive power line loss is reduced by more than 20%.

Switching process of capacity regulating is completed within 20ms-40ms, which could keep the power supplycontinuity of low side.


 

Scope of application

1.Be suitable for rural power grid where seasonal load variation is large. 2.Be suitableevelopment zones, industrial zone, etc. where diurnal loadvariation is significant.

Core: effectively upgrade transformer's no-load performance by below methods:

1) The core is made of high-permeable grain-orientated top quality cold-rolled silicon sheet and the material is cut with advanced Germany Geoge GmbH automatic shear line with the cut burs controlled within 0.02mm.

2) The silicon sheet fabrication adopts "no-upper yoke lapped' technology and all lapped joints of the silicon sheet are 45 full-miters. The laminated core sheets are integrally pressed and adhered with epoxy resin to make the three leg two-yoke core a strong and flat integral one with good verticality precision, this effectively improves no-load performance and reduces noises.

3) Bracing plates are used as support between coil leg and inner coil. The iron yoke is tied with epoxy resin-impregnated glass fiber band, and the lower section of oil tank is tightened with counter-pressure bolts. The upper iron and the upper section of oil tank are fixed at three locations. Hence the body inside the oil tank can withstand the vibration during transportation without any shift.

Winding:

1) The high-voltage (HV) coil adopts an interleaved-continuous structure to improve the voltage characteristics under impact voltage and make voltage evenly distributed. All stays and pads are chamfered to keep highly reliable insulation.

2) In the transformer winding there is a zigzag oil guide structure so as to fully cool all areas inside the winding, lower the temperature rise of the winding and the hot points of the winding and prolong the service life of insulation. The HV and MV regulation system are independently provided with voltage-regulating winding to balance the ampere turn of each winding, effectively lower the axial electrodynamic force generated at short-circuit of transformer and improve abrupt short-circuit withstanding capacity.

3) The winding adopts radial "0" margin designed, between the core and the paper sleeve of LV winding, and between the LV, HV, voltage-regulating windings, as well as before insertion of stays and shroud plate they are fully dried and tightly matched to ensure extremely good compactness and concentricity of the entire winding.

Oil tank and accessories

1) The tank wall adopts wide steel sheet, which will be folded into corrugated structure without splicing, in this way welds are decreased and mechanical strength is enhanced, meanwhile, the corrugated wall has diverging effect, and thus plays a role in decrease of noise. The routing troughs and control cabinets of the secondary circuit are all made of stainless steel, so the entire transformer has a simple and good looking.

2) All sealing surface use quality sealing material and are precision-machined.

3) On the edge of the tank there are double sealing grooves, and the outer sealing material is used to shade the atmosphere and ultra-ray to protect the inner sealing being damaged, thus at utmost prolonging service life and enhancing reliability of the seal.
