500KVA dry type transformer

Date of issue: 2020/8/25 9:19:58 Source: http://perryswenson.com Click: zero

   500KVA dry-type transformer is a new generation of power supply equipment developed according to the operation characteristics of railway and local power system. Compared with the transformer with traditional core structure, when the rated capacity, load loss, short-term impedance voltage and other indicators are the same, the measured value of no-load loss can be reduced by more than 30%, the no-load current can be reduced by more than 70%, and the noise level can be reduced by more than 5dB Ideal products for road and local power construction.

500KVA dry type transformer -- service conditions

1. Ambient temperature: - 15 ℃ - + 40 ℃

2. Altitude: < 1000M

3. Relative humidity: < 90%

4. The installation site shall be free of gas vapor, chemical deposition, dust, dirt and other explosive and corrosive media that seriously affect the transformer insulation.

5. Any special use conditions that do not meet the above provisions shall be determined by the user and our factory through negotiation.

Main technical features of 500KVA dry type transformer

1. Input voltage: rated voltage ± 10%

2. Output voltage: rated voltage + 5% (capacity load)

3. Efficiency: ≥ 95%

4. Waveform distortion: no additional waveform distortion

5. Function: input voltage, output voltage and current indication

6. Protection: with over-current protection

7. Long term unattended operation

8. Insulation resistance: ≥ 50m Ω

9. Electrical strength: power frequency sinusoidal voltage 2000V, no breakdown and flashover for one minute

10. Overload capacity: twice the rated current for one minute.

The definition of 500KVA dry-type transformer is relative to oil immersed transformer, which refers to the insulation transformer made by using non-liquid insulating medium to replace the oil medium solid gas of oil immersed transformer. For many non professional people, it can be simply summarized as: dry type transformer refers to the transformer whose core and winding are not immersed in insulating oil.

(1) it can operate directly in the fire prevention center without pollution;

(2) adopt domestic advanced technology, high mechanical strength, strong short circuit resistance, small partial discharge, good thermal stability, high reliability and long service life.

3. Low noise consumption;

(4) it has good heat dissipation performance and strong overload capacity, which can improve the capacity operation when forced air cooling;

(5) good moisture-proof performance, suitable for high humidity and other harsh environment.
