Product Details



BXB- /3300(1140,660)Y series apply to low-voltage protection box containing methane gas and coal dust mixed with the coal mine explosion gas, in the exchange of 50Hz, rated voltage of 3300V, 1140V, 660V,rated current to 1200A not neutral grounding of the three-phase power system, the installation of low pressure in the mobile substation adjacent to the low-pressure side of the grid fault monitoring and fault signal transmitted to the high voltage power distribution equipment, high voltage power distribution devices Mobile cut the high side power substation. The products and production company KBG series Mine Explosion proof mobile substation by supporting the use of high-pressure vacuum switch, as a rated capacity of 4000kVA and below Mining Explosion-proof mobile substations, low-voltage distribution switches, low voltage side of the common fault breaking, high pressure Power side with the rational mobile substation system.



  • Use together with KBG series ( high-pressure vacuum switch), composition of the international advanced operation mode which the low-pressure side fault breaking transformer high-voltage side breaker;
  • Intelligent use of advanced technology, Micro-controller, the sampling of high accuracy, anti-jamming capability is strong, flexible and reliable performance of action;
  • Using man-machine screen (using a keyboard and LCD) systems, parameter settings flexible, intuitive operation and fault screen concise;
  • A self-inspection system, fault diagnosis, Inspection and memory function;
  • Real-time detection and digital display operation status and fault instructions;
  • With overload, short circuit, leakage, and leakage atresia, overvoltage, under voltage, tripping and other backup protection;
  • Protect me divided into two loops bilateral likely to meet the requirements of more heavy-duty connections;
  • All the fault signal lines are driven by the high side power vacuum circuit high side to avoid the failure of the transformer windings burn major accidents;
  • Allocation standard RS485 communication interface, configuration KJ254 Mining power monitoring system, to remote-measure, telecommunication, remote-control and remote-regulation four functions, power supply equipment to achieve automation.
