Accompanying drawing explanation
Fig. 1 is a kind of circuit diagram controlling the remote control of blower fan described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the utility model controls the remote control of blower fan, comprise earth leakage circuit-breaker, A.C. contactor, manual push button switch, line bag, direct current relay and power & environment supervision switch, the first end of described earth leakage circuit-breaker is connected with three of three-phase alternating current phase lines, second end of described earth leakage circuit-breaker is connected with the first end of described A.C. contactor, second end of described A.C. contactor is connected and external Fan Equipment with three phase lines of three-phase alternating current, the described first end of line bag is connected with the neutral line of three-phase alternating current, second end of described line bag is connected with the first end of the contact switch in described manual push button switch and described direct current relay respectively, the second end of contact switch in second end of described manual push button switch and described direct current relay is connected with a phase line between the second end of described earth leakage circuit-breaker and the first end of described A.C. contactor, first termination negative voltage of the controller of described direct current relay, positive voltage is connect after second end of described direct current relay is connected with described power & environment supervision switch, the voltage at described direct current relay two ends is respectively-12V and+12V, the control signal input of described power & environment supervision switch is connected with the control signal output of power & environment supervision main frame.
Described controlling organization also comprises indicating device, and the two ends of described indicating device are connected with a phase line of the center line of three-phase alternating current and the second end of described A.C. contactor respectively.
The operation principle that the utility model controls the remote control of blower fan is as follows:
During normal work; earth leakage circuit-breaker QF closes a floodgate; if what have power & environment supervision main frame to send controls signal to power & environment supervision switch S; power & environment supervision switch S open in usual is closed; make the controller two ends of direct current relay J0 load 12V voltage, direct current relay J0 UNICOM immediately, after being communicated with, line bag J two ends load 220V interchange; the contact of A.C. contactor J-1 is communicated with, the Fan Equipment energising work of external AC 380V.
During shutdown maintenance, disconnect the 380V alternating voltage input of earth leakage circuit-breaker QF, now rotating ring control signal and manual operation, all can not make A.C. contactor action, guarantees personal safety when carrying out maintenance of fan.
If needs scene starts blower fan manually under normal circumstances, manual push button switch SB can be pressed, the two ends of line bag J load 220V alternating voltage, A.C. contactor J-1 contact is communicated with, external interchange 380V blower fan work, manually push-button switch SB makes line bag J two ends power-off, and blower fan enters distance control mode again.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion made according to the technical solution of the utility model, all falls within protection range of the present utility model.
