Description
The utility model relates to a kind of Micro-delayed action.
In the Industry Control of squirrel-cage asynchronous motor, often adopt rotating control or star angle conversion and control technology, its common feature all is to adopt two contactors that control is implemented in the commutation and the winding changing-over of motor, the changing-over moment of general contactor---promptly the time of energising only is not about 20 milliseconds to two contactors simultaneously, if breaking current is big, the arc extinction time is longer, just be easy to cause power supply short circuit.In order to address this problem, always be that the method for adopt adding auxiliary relay extends contact time at interval, this just makes control circuit wiring complexity, and erection space is bigger, and cost is also comparatively expensive.
The purpose of this utility model provides a kind of Micro-delayed action, and it can replace relay work in above-mentioned occasion and many control circuits.
The purpose of this utility model is achieved in that
Be the utility model circuit structure schematic diagram in the frame of broken lines among Fig. 1.
As shown in Figure 1: at input by four diode V1; V2; V3; V4 forms full-wave rectifying circuit (or by a full-wave rectification piece replacement); input voltage anode E point and controllable silicon V5 anode; dropping resistor R2 one end; protective resistance R1 one end links to each other; the other end D point of dropping resistor R2 and time delay resistance R3 one end; voltage-stabiliser tube V7 negative terminal and filter capacitor C1 one end link to each other; input voltage negative terminal O point and the filter capacitor C1 other end; delay capacitor C2 one end; storage capacitor C3 one end; the controllable silicon negative electrode; the protective resistance R1 other end and voltage-stabiliser tube V7 anode are connected; one two-way diode V6 one is terminated between time delay resistance R3 and the delay capacitor C2, and the bilateral diode V6 other end extremely links to each other with the storage capacitor C3 other end and controllable silicon V5 control.
The utility model circuit original paper is located on the printed substrate, and wiring board is installed in the housing, Inside is watered solid with epoxy resin, binding post and cold end terminal are drawn.
Each component parameters range of choice is as follows in the utility model circuit:
V1－V4 600－1000V，1A；
V5 400－600V，1－3A；
V6 20－35V；
V7 30－100V；
R1 51－330K；
R2 51－330K；
R3 1M－3.3M；
C1 0.02－1M／63V；
C2 0.047－1M／63V；
C3 0.22－1M／16V。
Wherein select can be up to 330K for the resistance of dropping resistor R2, and it is elusive according to conventional knowledge institute that this is those skilled in the art.
Operation principle of the present utility model is:
After input revolves making alive, through relay coil J, direct voltage UEO occurs in the full-wave rectification bridge dc terminal, UEO is UDO through dropping resistor R2 by voltage-stabiliser tube V7 voltage stabilizing, UDO gives storage capacitor C3 charging through time delay resistance R3, after storage capacitor C3 charging voltage reached bidirectional diode V6 puncture voltage, pulse current arrived the controllable silicon V5 control utmost point, the conducting so V5 is triggered through V6, make 2 short circuits of E, O, thereby make relay coil J energising adhesive.
By time delay resistance R3 and delay capacitor C2 decision, delay time can be adjusted (comprising relay-operating time) between 30-1000ms, generally transfer to 40-80ms and get final product between coil J on-delay.Delay precision is higher than 10%, and the controlled electric appliance coil voltage can be approximately
110V-
220V can redesign parameter during other voltage request.
The utility model voltage-stabiliser tube V7 is in little current work state (less than a milliampere), so the controlled controllable silicon that loads on does not have before the conducting, its leakage current is less than 2 milliamperes.
