Mining Flameproof Movable Substations (KBSG9)

The mineral product separates the explode migration transformer substation separates the explode migration transformer substation by the mineral product with the do -like transformer, the high-pressured load switch either the high pressure and the low pressure switch or the low pressure guarantees is composed. It has creepage, creepage closedown, overload, short-circuits, overvoltage and so on protection feature.Functional characteristics Rated Capacity (KVA): 50 1600 KVA Vecor Group: Yy0 or Yy0(d11) Impedance Voltage (%): 4%, 4.5%, 5% Rated voltage: H. V: 10, 6KV (Or as customer requirement) LV.: 0.693/0.4, 1.2/0.693, 3.45KV (Or as customer requirement) Frequency: 50Hz Standards: GB8286-2005 GB3836-2000 GB/T10228-1997 JB/T56152-94Service conditions 1. The installation is not nigher than 1000m (usual normal), special Environment gives explanation in addition. 2. Ambient temperature Highest temperature: 40º C Maximum monthly average temperature: 30º C Maximum annual temperatures: 20º C Lowest temperatures: -5º C 3. The surrounding air relative humidity is not greater than 95% (25º C ); 4. In the mine, with methane, dust, explosion danger is well; 5. No vibration the gradient is less than 15º C; 6. No gas or steam to corrade metal or destroy insulation; 7. Non- water drop site; 8. Voltage profile is approximate to the sine wave; 9. The three-phase supply voltage approximate symmetrical. Note: When exceed this condition stipulation, consultation is needed.Scope of application KBSGZY series mining flameproof movable substations is a kind of movable whole set for power supply and transformer. It is suit mine filled with fire damp mixed gas, grime and explosive gas; The gas and steam environment that can not erode metal or destroy insulation.
