Abstract
The utility model discloses an automatic transfer switch controller with integrated fire control. The automatic transfer switch controller comprises a photocoupler, a shunt resistor and a microprocessor which can send out instructions for starting a control motor with double power supplies according to the integrated fire control signal. The integrated fire control signal end is connected with aninput end of the photocoupler; a first output end of the photocoupler is grounded; a second output end of the photocoupler is connected with the shunt resistor and an integrated fire control signal interface of the microprocessor; and the microprocessor also comprises a motor control end which is connected with the control motor. The utility model provides an automatic transfer switch controller with integrated fire control which has lower cost and good reliability.
Description
Technical field
The utility model relates to a kind of controller of automatic transfer switching electric appliance.
Background technology
At present, automatic change over fire protection linkage control scheme: with reference to Fig. 1, wherein K1 is an electromagnetic relay, and L1, L2 are shunt release, and NAF, NN, RAF, RN are for taking from the load end power supply; Put a shunt release respectively in two execution isolating switchs of automatic change over, control end one tunnel directly connects load end power supply N phase, and another control end inserts electromagnetic relay normally opened contact two ends respectively mutually with load end power supply A.The fire protection linkage control signal connects the electromagnetic relay control end.After the fire protection linkage control signal sends, drive the shunt release action, thereby cut off load power source, realize fire protection linkage control.
The defective that exists is: (1), cost are higher: the increase cost with current class also increases; (2), poor reliability: adopt two shunt releases and an electromagnetic relay to cooperate, and shunt release turn-on current in short-term only, long-term energising can be burnt, and this has improved requirement to the fire-fighting link control signal, must be short signal, or adopt moving disconnected button.Also to consider the reliable in action of shunt release and electromagnetic relay.
The utility model content
For the cost height that overcomes existing automatic change over fire-fighting link device, the deficiency of poor reliability, the utility model provides that a kind of cost is lower, the automatic transfer switch controller of the band fire protection linkage control of good reliability.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of automatic transfer switch controller with fire protection linkage control, comprise photoelectrical coupler, shunt resistance and the microprocessor that instructs in order to the control motor that sends the startup dual power supply according to the fire protection linkage control signal, the fire protection linkage control signal end connects the input end of photoelectrical coupler, first output head grounding of described photoelectrical coupler, second output terminal of described photoelectrical coupler connects the fire protection linkage control signaling interface of shunt resistance and microprocessor, and described microprocessor also comprises the Electric Machine Control end that is connected with described control motor.
As preferred a kind of scheme: described Electric Machine Control end comprises that motor is just changeing control end and motor counter-rotating control end.These two control ends are controlled two control motors of dual power supply respectively, can control two-way power supply and load and disconnect simultaneously.
Technical conceive of the present utility model is: be provided with the fire protection linkage control signaling interface in automatic transfer switch controller inside, link to each other with embedded microprocessor by the light lotus root, after receiving the fire protection linkage control signal, embedded microprocessor sends drive signal automatically, the corresponding action of doing the control motor of driving dual power supply realizes that two-way power supply and load disconnect (two minutes states) simultaneously, and control mode is changed to manually, need manually-operated can be changed to automatically.
The beneficial effects of the utility model mainly show: 1, cost reduces greatly, only uses a slice light lotus root and a shunt resistance, its cost only a yuan less than, mainly realize, and can series of products general, with current class and irrelevant by program; 2, adopt a slice light lotus root and a shunt resistance, and the embedded microprocessor automatic control motor; At first talk signal and accept, the fire protection linkage control signal can be connected always, and light lotus root and resistance belong to not fragile element, and its electric property is superior; The control motor of automatic change over belongs to motor special, has excellent anti-stall performance, adds embedded microprocessor and controls automatically, and its reliability is much better than shunt release of the prior art.
Description of drawings
Fig. 1 is the circuit theory diagrams of existing automatic change over fire protection linkage control.
Fig. 2 is the circuit theory diagrams of automatic transfer switch controller of the application's band fire protection linkage control.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See figures.1.and.2, a kind of automatic transfer switch controller with fire protection linkage control, comprise photoelectrical coupler 1, shunt resistance 2 and the microprocessor 3 that instructs in order to the control motor that sends the startup dual power supply according to the fire protection linkage control signal, the fire protection linkage control signal end connects the input end of photoelectrical coupler 1, first output head grounding of described photoelectrical coupler 1, second output terminal of described photoelectrical coupler 1 connects the fire protection linkage control signaling interface of shunt resistance 2 and microprocessor 3, and described microprocessor 3 also comprises the Electric Machine Control end that is connected with described control motor.
Described Electric Machine Control end comprises that motor is just changeing control end 4 and motor counter-rotating control end 5.Microprocessor 3 is an embedded microprocessor.
In the present embodiment, the fire protection linkage control signal end is+24V and-24V, shunt resistance connection+5V.
After receiving the fire protection linkage control signal, microprocessor 3 sends drive signal automatically, the corresponding action of doing the control motor of driving dual power supply realizes that two-way power supply and load disconnect (two minutes states) simultaneously, and control mode is changed to manually, needs manually-operated can be changed to automatically.
