Technical field
The present invention relates to the control box technical field, especially a kind of mine flameproof and intrinsic safety type electric device for valve control box.
Background technique
Along with the colliery automatization level improves, manually-operated gate has been difficult to adapt to the needs of modern technologies development in recent years, and manually-operated gate can't detect valve and whether have electric leakage.Short circuit, overload, under-voltage, cross situation such as moment, can't carry out telecontrol, using effect is not good.
Summary of the invention
In order to overcome the deficiency that existing manually-operated gate can't satisfy mine automation requirement, the invention provides a kind of mine flameproof and intrinsic safety type electric device for valve control box.
The technical solution adopted for the present invention to solve the technical problems is: a kind of mine flameproof and intrinsic safety type electric device for valve control box, comprise power module and transformer, and it is characterized in that; Said transformer connects isolation conversion switch and leakage protection module, and said isolation conversion switch connects fus, and fus connects fuser motor; Fuser motor connects A.C. contactor, and A.C. contactor connects permissible motor, and said leakage protection module connects intrinsic safety isolation module, potentiometer and control module; Said intrinsic safety isolation module and potentiometer link control module; Said intrinsic safety isolation module connects rotary switch, and said rotary switch connects power module and control module, and said control module connects position limit switch and liquid crystal display; Said position limit switch connects torque switch, said torque switch link control module.
The invention has the beneficial effects as follows; This mine flameproof and intrinsic safety type electric device for valve control box; Have functions such as earth leakage search/lockout, short-circuit protection, overload protection, under-voltage protection, mistake force moment protection, open-phase protection, the automatic correction of intrinsically safe circuit phase sequence discriminating; And can a distant place, control is switched on the spot, thereby control box is used in automatic system more extensively, reliably.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a framework schematic representation of the present invention;
Comprise among the figure: power module, transformer, isolation conversion switch, fus, fuser motor, A.C. contactor, permissible motor, leakage protection module, intrinsic safety isolation module, rotary switch, potentiometer, control module, position limit switch, torque switch and liquid crystal display.
Embodiment
Like Fig. 1 is framework schematic representation of the present invention, and a kind of mine flameproof and intrinsic safety type electric device for valve control box comprises power module and transformer; It is characterized in that said transformer connects isolation conversion switch and leakage protection module, said isolation conversion switch connects fus; Fus connects fuser motor, and fuser motor connects A.C. contactor, and A.C. contactor connects permissible motor; Said leakage protection module connects intrinsic safety isolation module, potentiometer and control module, said intrinsic safety isolation module and potentiometer link control module, and said intrinsic safety isolation module connects rotary switch; Said rotary switch connects power module and control module; Said control module connects position limit switch and liquid crystal display, and said position limit switch connects torque switch, said torque switch link control module.
This mine flameproof and intrinsic safety type electric device for valve control box can effectively detect the working condition of valve, finds the situation of electric leakage; Can cutting off the electricity supply automatically, it is unexpected to avoid occurring; When short circuit, overload, situation such as under-voltage appear in control box, also can cut off the electricity supply, stop the running of control box, the safety of protective circuit; The situation of moment appearred in permissible motor; Also interruptible power plays the effect of protection permissible motor, thereby it is more extensive, reliable that control box is used in automatic system.
