BPJ-400(250, 110)/1140(660) Mining Flame-Proof and intrinsic Safety AC Frequency Converters/ Mining Machinery

Function:
The GPJ BPJ-400(250, 110)/1140(660) Mining Flame-Proof and intrinsic Safety AC Frequency Converters apply to underground coal mines where contain explosive gas (methane) and coal duct. Power spare part (IGBT), filer an eclectic capacity and control core etc. main spare part adoption import product, promised the credibility of long-term movement. This product adoption vector control technique, have perfect electrical engineering protection and goodly adjust soon function, can carry out electrical engineering of soft stop, according to burden circumstance, automatically regulate electrical engineering speed, let up an electrical engineering start to having no of charge barbed wire net achievement impact, spread a feeling machine through and equipment outer circle I the meantime, dynamic stage control can carry out to change to measure, attain an economy energy purpose, be applicable to coal mine well flameproof promote machine, tape of conveyance machine, pare off the electricity control of the plank conveyance machine, the pump equipments, such as station and breeze machine etc.

Character:
1. The adoption has no speed to spread feeling machine vector, 0.5Hzs the exportation turn Ju to attain a sum to certainly turn 1.5 times than of Ju, the biggest exportation changes the Ju into the sum to settle to turn 2 times that of Ju.
2. Choose the hot tube spreads a hot way and promise that the equipments circulates of spread a hot request, lower a system voice, carry out to don't need a maintenance.
3. The comprehensiveness carries a demand that the frequency regulates scope(2~16KHZs) and satisfy different situation.
4. Canning chooses according to the different load property is different of making and moving way: The direct current system moves, the dynamic state system move, the feedback system move.
5. Person's machine picks up a people adoption essence safe type electric circuit carry on insulation and promised the safety of equipments and operate convenience.
6. Multiple protective functions for overload, short circuit, loss of phase, eclectic leakage lockout, over voltage, under voltage etc.
7. Standard RS485 communication interface.
8. The system has good electromagnetism and permits.
9. Have long rage diagnosis ability.
