1 environment temperature: -15 ~ +40 (c)
2 altitude: <2000m
3 relative height: <90%
No serious effect of gas steam, transformer insulation 4 single-phase transformerinstallation place gasification precipitation, dust, dirt and other explosive and decadent medium;
The relative humidity of 5 single-phase transformers atmosphere around the air humidity is not more than 50 ℃ +40 ℃, relative humidity in low humidity can behigh, humidity maximum average wet month was 90%, while the average minimumtemperature for the month of +25% taking into account due to temperaturechanges occur in the solidified product surface;
Special conditions of the 6 that do not meet the above conditions, by using the conception and I companies determine.
Three, the technical parameters
Voltage rating: 1KV
Rated capacity: 5 ~ 320 (KVA)
The connection group: 1iO
Power frequency withstand voltage: 3KV/min
Insulation grade: F/H
Core temperature limits: not more than 85K, the coil temperature does not exceed 95K
