Product Description
20kv three phase double winding distribution transformer with off load tap changer
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 silicon steel sheet,with laminated structure miter joint,so as to reduce the no-load losses and no-load current. the tank is a corrugated type,the corrugated fins can swell and shrink with the change of transformer oil,so that the pressure can be maintained inside the tank,increase its reliablility and anti-corrosion capacity.the coil of distribution transformer,wound by high intensity enameled wrapped conductors with good ampere-turn balance and reasonable insulation structure. has a strong short-circuit withstand capacity.the distribution transformer adopts the free-untanking structure. with sealing material parts made of high quality acrylic rubber,it can effectively prevent againest ligh-aging and heat-aging.
Capacity: 30~2500kva
Voltage :20± 5% or ± 2x2.5% LV:0.4KV
Vender group:Yyn0 or Dyn11
Impedance:5.5%, 6%
the loss value also apply to high voltage double voltage 20(10) three phase transformers.
Specifications
It has the features of high efficiency and low loss, can save a lot of operation cost
This type of transformer adopts high-permedibility cool-rolling si-steel piece as iron core.It is processed with big fill factor and there is no spacing inside the mangnetic path. The HV and LV coil is continuously winded around the core with good concentricity and compact winding. The product is of low con-sumption and slight noise pollution by combining new generation of technolgy good performance and energy saving. It is widely used in power distribution system.
IEC 60076 -1-2-3 2000 Power Transformer
GB1094.1-2-1996 Power Transformer
GB1094.3-5-2003 Power Transformer
GB/T6451-1999 Technical parameters and requirements for three-phase oil-immersed power transformer.
| Performance characteristics |
1. The features of this product are high efficiency and low loss.It can save a lot of operation cost,and the social benefits are very significant.
2. The iron cores are made of the imported high-conduction magnetism,cold-roll,and grain-oriented silicon-steel sheets.The iron cores and windings adopt the vacuum drying and vacuum oil-filling processes,which make the internal moisture down to the very low level.
3. The conservator is hermetically sealed,which make the internal running oil to insolate with oxygen and moisture efficiently.
4. The above features guarantee the transformer does not need do replace the oil during the normal operation,greatly decrease the maintenance cost,and prolong the service.
