Product structure and process characteristics
Transmission and distribution system from the remote power plant will be transferred to the user through the regulation of energy transmission through the high-voltage transmission lines, and then step-down substation in several levels in order to be suitable for users. The distribution transformer located near the final power user will eventually drop the voltage to the appropriate value. The voltage is reduced to the electrical equipment operating voltage transformer is called distribution transformers, such transformers as daily lighting and factory power, the general low voltage of 0.4kV and below. Distribution transformer capacity is small, generally 2500 kVA and below; a voltage is also low, are 35 kV and below. Different from the ordinary oil-immersed transformer, our company's full-sealed distribution transformer eliminates the oil conservator, the corrugated tank body's fin plate as a thermal expansion and contraction components, the transformer oil and the atmosphere completely isolated. The distribution transformer consists of a capacity transformer and a dual voltage distribution transformer. Capacity transformer is a capacity of two sizes, and can be adjusted according to the size of the load distribution transformers. High voltage winding connection mode changes, low-voltage winding and the series conversion and the adjustment of the tap parts are made by a special non-excitation capacity adjustment switch to complete. At the same time, large capacity to small capacity, due to the increase in low-voltage turns, the core magnetic flux density significantly reduced, leaving silicon steel unit loss decreases, no-load loss and no-load current is reduced, to reduce energy loss the goal of. Dual-voltage distribution transformer is a size of two voltage, and can be adjusted according to the grid voltage distribution transformers. High-voltage winding and, in series conversion and the adjustment of the tap parts are made by a special non-excitation switch.
In this case,
Features:
Distribution transformer using CAD design, performance in line with IEC60076, GB1094, GB / T6451 standard. The distribution transformer cores are made of cold-rolled grain-oriented silicon steel sheets, which are manufactured by the automatic production line using the step-lap process. Distribution transformer tank for the corrugated tank, GEOGE by the German company automated tank production line processing, surface treatment and coating powder powder are used international brand products, the tank automatically by the production line degreasing, pickling, phosphating, electrophoresis before the spray after treatment Powder, and then high-temperature curing, transformer corrosion-resistant appearance of strong. Distribution transformer coil with high-strength enameled wire (or paper wire) winding, ampere-turn distribution, insulation structure is reasonable, with strong anti-short circuit ability. Distribution transformer body with hanging core structure, the use of high-quality acrylic rubber seal, can effectively prevent the light aging, heat aging.
 
 
specifications:
1, the voltage level: 10kV;
2, voltage regulator: no excitation or on-load voltage regulator;
3, tap range: ± 5%, ± 2X2.5% or ± 4X2.5%;
4, the capacity range: 30-25000kVA;
5, the frequency: 50Hz, 60Hz;
6, single-phase, three-phase;
7, the junction group label: Yyno or Dyn11 (or according to user requirements);
8, short-circuit impedance: in accordance with national standards or according to user requirements;
9, the use of the environment: relative humidity of 100%, the ambient temperature is not higher than 40 ℃ (or according to user requirements);
10, the cooling method: AN;
11, the insulation level:
① 10kV-class products frequency withstand voltage 35kV, 75kV impulse withstand voltage,
