Features of prouducts
The KBSG series mining explosion isolation dry
transformer conforms 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, a primary voltage
is 6 kVs or 10 kVs, andneutergender 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.
Operating environment and working conditions
1, The installment highly does not surpass elevation 1000m, the special environment gives the explanation in addition
2, Ambient temperature
Highest air temperature +40c:
Highest daily average air temperature+30C;
Highest annual average air temperature+20C:
Lowest outdoor air temperature-5c.
3, The surrounding air relative humidity is not bigger than 95%(+25C when)
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. The supply voltage profile is approximate to the sine wave;
9. The three-phase supply voltage approximate is symmetrical
