Product Description

 

  

Overcurrent Protection Power Transformer Substation 11/0.4kV with 250kVA 

 1. Application

1). Our power transformers are especially suitable for installation in draw-out type or fixing type switchgears as well as for power plants, substation, self-consumption transformers, power distribution, transmitter system, earthing system, community power supply system, subway, or those places where small space, fire-control, moisture-proof, are needed. Those up to 10kV can be installed in 650 ~ 1200 mm wide switchgear, up to 20kV in a 1000mm wide switchgear and 35kV in 1400 ~ 1600 mm wide switchgear.

2).Our series reactors are suitable for a power system of 6~10kV.They are connected serially with high voltage parallel capacitor group to depress a wave deformation in the system.

2.Technical Parameters

1).Rated Primary Voltage: 6kV up to 35kV

2).Rated Secondary Voltage: 0.4kV

3).Rated Capacity: 3kVA up to 2500kVA

4).Rated Short-time P. F. Withstand Voltage (r.m.s.) (kV): 20, 25, 35, 50, 70

5).Rated Lightning Impulse Withstand Voltage (Peak) (kV): 60, 75, 125, 170

6).Phase No.: single phase or three phases

7).The Highest Temperature Rise of Windings: 100K

8).Insulation Class: F

9).Cooling Mode: AN or FN

10).Enclosure Protection: IP00, IP20 or custom specified

11).Connection Symbol: Yyn0, Dyn11or II0 or custom specified

12).HV Tapping Range (%): ±5 or ±2×2.5

3. Main Features

1).Low loss, low noise, high operation efficiency
2).High ability of protection against short circuit

3).High mechanical strength   
4).Pre-galvanized steel frame, flame-resistant, against corrosion

5).With outstanding fire-proof capability: the epoxy resin is difficult to flame and self-extinguished. So it won’t lead to the second disasters, such as an explosion.

6).Cast epoxy resin with high dielectric strength 18~22kV/mm in vacuum process

7).Superior in environmental performance: the epoxy resin is very stable, moisture-proof and dust-proof. It enables dry-type power transformers to run with high reliability under abominable environment.

8) With theimpeccable temperature control and indicating system, dry-type power transformers can be maintenance free. And this offers a great reduction of operation cost.

9).With small volume, light and convenient for installation and alignment

10).No need of a separated room

4. Materials

1).Insulation Material: epoxy resin

2).Winding Material: Aluminum wire or high quality enameled copper wire (foil winding is available for power transformer)

3).Core: core lamination, low loss, cold rolled grain oriented silicon steel
