Product introduction:
Load regulating power transformer is developed and produced according to the requirement of the market. It can be widely used in urban &
rural, industrial & agricultural power network, which has a great significance for energy-saving and environment protection. The lamination
method of this product's iron core is ladder form,instead of the traditional iron core lamination technology, which improves the magnetic
circuit distribution inside the iron core. It can be seen as a revolution of transformer iron core manufacturing. Compared with the traditional,
the no-load loss, no-load current and noise of the new one decrease 20% respectively, and load loss decreases 10%. The new product
applies CAD, with advance design, reasonable structure, and excellent materials. Each index complies with the standards of GB1094-1996 "
Power Transformer" GB/T6451-1999"Technical Parameters and Requirements of Three-phase Oil-immersed Type Power Transformer". Now
its level is the leading position of our country.
Features:
High reliability, advanced level of performance, economic indicators and reasonable;Using phase-shaped core of three joints, curing paint
brushing the surface to reduce wear and tear and noise;Winding structure of a new oil road design is reasonable, with the new insulation to
improve the mechanical strength and the ability to engage in short-circuit;Tank forms, beautiful, generous.
Technical parameters:
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.
Model:DH15-M-80/20
Rated Capacity (KVA):80
No-load Loss (W):70
Load Loss (W):1400
Short-circuit Impedance (%):3.5
No-load Current (%):0.9
Gross Weight:620
Dimension of Ordinary Type (mm):LxWxH=805x780x1350
Dimension of CSP, SP and Types: 805x780x1600
In the decentralized power distribution network, single-phase transformer as a distribution transformers have a greater advantage, it can be
reduce the low voltage length of distribution lines, reduce line Loss, improve quality of power supply. Adapt core volume using energy
efficient design, the transformer feature is adapt to column suspension installation, small volume,small investment in infrastructure,reduce
low voltage power supply radius, can reduce line loss of more than 60%. Transformer with fully sealed structure, strong overload capacity,
continuous operation reliability and simple maintenance.
Suitable for rural power grids, remote mountainous areas, dispersed villages, agricultural production, lighting and power electricity, it can also
be used in railways, urban energy-saving column grid type distribution lines.
