Abstract
An automatic delay switch of a corridor controls the switch of a lamp by means of a thyristor. Two RC circuits with the same parameters repetitively generate timing signals by the switching of a switch (K), the timing signals determine the working state of a diode, in which the diode is either isolated from the ground or short-circuited to the ground, and as a result, the thyristor is either triggered to be conducted or not triggered to stay in the state of cutoff. Consequently, compared with kindred devices, the utility model has the advantages of simpler structure and lower cost.
Description
The utility model relates to a kind of corridor Auto-delay switch.
The existing delay switch of controlling with controllable silicon, its silicon controlled triggering signal delay control circuit is very complicated usually, and cost is higher.
The purpose of this utility model provides a kind of circuit structure Auto-delay switch simple, with low cost.
The purpose of this utility model is achieved in that by power supply 220V AC sine wave is carried out full-wave rectification and electric resistance partial pressure, obtain and the complete synchronous triggering signal of mains voltage waveform, this signal determine to isolate by the triode operating state that links to each other with timing circuit with ground or and ground short circuit, thereby trigger or do not trigger controllable silicon, make the controllable silicon conducting or end.Therefore, compare with existing same device, structure is more simple, cost is cheaper.
Implementation process of the present utility model specifies in conjunction with the accompanying drawings by a following example, and accompanying drawing is the circuit theory diagrams of corridor Auto-delay switch of the present utility model.
This circuit partly is made up of DC power supply part, timing part, alternating-current switch.
The DC power supply part is made up of full-bridge B1, resistance R 4, voltage-stabiliser tube Z1 and capacitor C 1.After voltage-stabiliser tube Z1 and capacitor C 1 parallel connection, the one end links to each other through the output head anode of resistance R 4 with full-bridge B1, and the other end links to each other with the negative pole of output end of full-bridge B1.
Alternating voltage forms voltage galvanic current source after load lamp RL, resistance R 4 step-downs, full-bridge B1 rectification, voltage-stabiliser tube Z1 and capacitor C 1 voltage stabilizing, the A point is a positive voltage terminal, and the B point is the common ground end.
Regularly part is made up of K switch, capacitor C 2, C3, resistance R 6, R7, R5, R8, diode D2, D3, and capacitor C 2 (or C3) is connected with resistance R 6 (or R7), and is in parallel with resistance R 5 (or R8) then.Capacitor C 2 is corresponding fully one by one with C3, resistance R 6 and R7, constitutes two identical RC parametric circuits.
When K switch is in arbitrary position of 1 or 2, electric current charges to capacitor C 2 (or C3) through capacitor C 2 (or C3), resistance R 6 (or R7), C point (or D point) current potential is changed to zero level by high level, the length of transformation period is by capacitor C 2 (or C3), resistance R 6 (or R7) decision, thus the realization timing function.
Resistance R 5, R8 are used for constituting the charge discharging resisting loop of capacitor C 2, C3.
The alternating-current switch part is made up of controllable silicon S1, full-bridge B1, resistance R 2, R3, triode T1, T2, diode D2, D3.
Two ac input ends of full-bridge B1 link to each other with an end of load lamp RL and AC power respectively, and continuous, resistance R 2 links to each other with two outputs of full-bridge B1 with R3 series connection back.
Resistance R 2 is connected with R3, and its tie point extremely links to each other with the collector electrode of triode T2, the control of controllable silicon S1.
The positive pole of diode D2, D3 links to each other with C, D point respectively, and the negative pole of diode D2, D3 links to each other with the base stage of triode T1, and the collector electrode of triode T1 links to each other with the base stage of triode T2.
The 220V alternating current produces a sinusoidal wave level signal at the E point after full-bridge B1 rectification, load lamp RL, resistance R 2, R3, dividing potential drop, this signal acts on the control utmost point of controllable silicon S1, and determines whether to trigger controllable silicon jointly with the state of triode T2; This signal phase and AC power are synchronous fully, and its amplitude is by load lamp RL, resistance R 2, R3 decision.
C point (D point) level acts on the base stage of triode T1 through diode D2 (or D3), its level by high level when zero level changes, triode T1 is become by conducting and ends, triode T2 becomes conducting by ending, the triggering level signal that E is ordered becomes and ground short circuit by isolating with ground, thereby realizes the conversion of the on off state of controllable silicon S1.
In the back and forth transfer process of K switch, make controllable silicon S1 become the process of ending after conducting a period of time and occur repeatedly, thereby realize automatic time delay turn-off function repeatedly of the present utility model in position 1 or 2.
