Features of Products

 

The KBSG series mininq explosion isolation dry transforrner conforrns to new GB 8286, mineral product separates explode migration transformer substation requests. Insulating the material adopts C class or H class to insulate, hot stability good, cooling offway a doption ANAN, be applicable to there are air and coal dust of the methane mixture, and there is the mineral well, mineral mountain, tunnel of explosion danger etc. environment, also be app licable to shortage with air and steam environment which decays metals and breakage to insulate. Settle the frequency as 50 Hz. aprimary voltage is 6 kVs or 10 kVs, andneuterqender not to connect ground for the power system, for use various motive equipments in the environment with various use electricity device to provide power supply.

JB3955-1993;GB1094.1~2-1996;GB12173-2008;GB1094.3-2003;GB1094.5-2008

Using environment and working condition

1. The elevation is less than 1000m, the special environment gives the explanation in addition
2. Ambient temperature: Highest temperature+40℃; Lowest temperature-5℃; Maximum daily average temperature +30℃; Maximum annual average temperature +20℃; Lowest outdoor air temperature-5℃;
3. The relative humidity is less than 95%(When the air temperature is 25℃);
4. In has the methane and the coal dust, also has the explosion hazard in the mine pit;
5. Does not have, the vibration as well as with the gradient does not surpass in 15 environment;
6. Does not have sufficiently the dipping and the insulation gas and the steam;
7. No-water drop place;
8. Power supply voltage profile is approximate to the sine wave;
9. The three-phase supply voltage approximate is symmetrical;(When extracts this condition stipulation, separate consultation)
