DG and SG series single - phase and three - phase dry type transformer adopts high quality material and advanced technology , it has advantages of damp - proof and convenient maintenance, it can be applied to such power transmission and distribution places like underground railway , high building, airport, station, wharf, enterprise, tunnel, etc. It is mainly used in power supply occasions of AC 50~60Hz and voltage less than 500V. All the input and output voltage , connection group and capacity of tapped winding can be designed and produced according to users’ requirements.
Working conditions (SG series three-phase dry type transformer)
1.Ambient air temperature: -5°C~+40°C, the highest monthly mean temperature should not exceed +30°C;
2.Altitude for installing place should not exceed 1000m;
3.When the ambient air temperature is +40°C, the relative humidity should not exceed 50%, and it allows higher relative humidity under lower temperature. Max average humidity in the dampest month is 90%, meanwhile the lowest average temperature of this month is + 25°C, and condensation on the product surface caused by temperature change should be taken into consideration.
Main technical characters
1.Input voltage: rated voltage ±10%
2.Output voltage: rated voltage +5% (no load)
3.Efficiency: ≥95%
4.Waveform distortion: no additional waveform distortion
5.Function: indication of input voltage, output voltage and current.
6.Protection: over-current protection
7.Can operate itself without anybody attending for a long term
8.Insulation resistance: ≥50MΩ
9.Electric strength: no breakdown or flashover phenomenon under power frequency sine voltage of 2000V for 1min
10.Overload capability: for 1min under two times of rated current
