Abstract
The utility model relates to a 3-phase non-contact switch controlled by singlechip, relating to application of singlechip technique in control area, comprising an I/O interface of singlechip and two-way circuit of SCR. The singlechip I/O input is connected with touched switch, which one end is connected to I/O input and another end is grounded through anode of power supply. Through switch tube, the singlechip I/O output is connected with triggered control terminal of two-way SCR, which one end is connected to one end of load, which another end is connected to one end of power supply, which another end is connected to the another end of two-way SCR. Through the operation of touched switch, the utility model can control the operation of switch to realize the control of non-contact. The advantage is that it uses light current to control heavy current to change the contact control manner used in current switch technique, eliminates the influence caused by electric arc at the moment of switching on the switch contact and delays the switch closing to realize the purpose of using electricity safely and saving electricity.
Description
Technical field the invention relates to a kind of noncontacting switch, and particularly a kind of monolithic processor controlled three-phase contactless switch belongs to singlechip technology in the control Application for Field.
Before background technology the invention applying date, threephase switch is contact switch, and also there is hidden danger in the influence that exists the electric arc of switch moment that switch contact is caused in practical operation.Related switch does not have time-delay closing function, is unfavorable for electrical energy saving.
The purpose of summary of the invention the invention provides a kind of monolithic processor controlled three-phase contactless switch.
The invention solves the technical scheme that its technical problem adopts: comprise single-chip microcomputer input/output interface and bidirectional triode thyristor circuit; The single-chip processor i/o input is connected to touch-switch, and the single-chip processor i/o output is connected with the bidirectional triode thyristor trigger control end by switching tube.Touch-switch with the connected mode of single-chip processor i/o input is: the one end is connected with the single-chip processor i/o input, and by resistance positive source, other end ground connection; Three I/O outputs of single-chip microcomputer are connected with three bidirectional triode thyristor trigger control end by three switching tubes, one end of one termination load of bidirectional triode thyristor, the other end of load is connected with power supply one end, and the other end of power supply is connected with the other end of bidirectional triode thyristor.
The beneficial effect of the invention is: light current control forceful electric power, change the contactor control in the existing switching technique, and overcome the influence that the electric arc of switch moment causes switch contact, and the function with automatic delay function realizes safety utilization of electric power and electrical energy saving.
