Abstract
The utility model provides a delayed conducting solid-state relay, which comprises a rectifying voltage stabilizing circuit, a delayed control circuit, an optical coupler trigger control circuit and a load protecting circuit. When control signals are input, required voltage value is reached by the rectifying voltage stabilizing circuit, time delay is set by delay controlling after the voltage is stabilized, an optic coupler is triggered so as to supply gate pole trigger current to a thyristor after the time is delayed, and the relay works in a delayed manner. Air condition compressors and other places with unstable current and voltage can be protected by means of delay conducting of electric power, so that electric appliances can be protected assuredly.
Description
Technical field
The utility model relates to a kind of solid-state relay, particularly a kind of time-delay conducting solid-state relay that is mainly used in compressor of air conditioner protection and the unstable place of some supply voltages.
Background technology
At present in the unsettled place of some supply voltages, use air conditioner often to occur sending a telegram here again after the outage at once, this situation can cause more serious problem easily, and such as being easy to generate the fault of burning compressor, general solid-state relay also can't be avoided this problem.
Summary of the invention
In order to solve prior art problems, the utility model proposes a kind of on-delay that is applied to air conditioner and start protection relay.When at each incoming call, utilize the air conditioner on-delay to start protection relay, to the control circuit time-delay energising in 15～25 seconds of air conditioner.
For realizing the purpose of this utility model, the technical scheme that the utility model is taked is to adorn the electronic switch that an on-delay starts protector control on air conditioner, utilizes low-voltage control high voltage.In the unsettled place of supply voltage, use this air conditioner on-delay to start protector, after the air conditioner outage, no matter when send a telegram here again, can therefore not produce the fault of burning compressor.Be specially, energization delay relay is failure to actuate behind relay power, starts by the time delays of setting.When outage is sent a telegram here again, open air-conditioning after time-delay a period of time automatically.
For reaching the purpose of this utility model, time-delay turn-on relay of the present utility model comprises regulator rectifier circuit, delay control circuit, optocoupler trigger control circuit and load protection circuit.Utilize described time-delay turn-on relay to start the electronic switch of protector control as the air-conditioning on-delay.
The beneficial effects of the utility model are by on-delay protection relay delayed startup air-conditioning, help to protect air-conditioning to break down when frequent power on/off takes place, and prolong the useful life of air-conditioning.
Description of drawings
By the detailed description below in conjunction with accompanying drawing, aforesaid purpose, the feature and advantage with other of the utility model will become apparent.Wherein:
Figure 1 shows that structure composition schematic diagram of the present utility model;
Figure 2 shows that circuit theory diagrams of the present utility model.
Embodiment
As shown in Figure 1; time-delay conducting solid-state relay of the present utility model comprises regulator rectifier circuit; delay control circuit, optocoupler trigger control circuit and load protection circuit, wherein said delay control circuit are located between regulator rectifier circuit and the optocoupler trigger control circuit.
With reference to Fig. 2; when relay of the present utility model is worked; when the input energising; through the rectifier bridge rectification, capacitor filtering obtains galvanic current; carry out step-down by the JIC voltage-stabiliser tube; voltage is dropped under the operating voltage, set delay time by J1, LED lights; input circuit work; through the resistance step-down, make voltage reach optocoupler operating voltage interval, optocoupler triggers; for controllable silicon provides gate trigger current; time-delay relay work, RC absorbs and does over-voltage over-current protection in output loop, realizes the trouble free service of time-delay relay.
Time-delay turn-on relay of the present utility model reaches the requirement magnitude of voltage by regulator rectifier circuit when control signal is imported, control by time-delay after the voltage stabilizing, realize setting time-delay, delay adjustments is after the time, and optocoupler triggers to the gate circuit transistor gate trigger current, time-delay relay work.Utilize the on-delay conducting, be used for the unstable place of compressor of air conditioner protection and some supply voltages, realize certain protection electrical equipment.
The utility model is not limited to described embodiment; those skilled in the art is not breaking away from spirit of the present utility model promptly openly in the scope; still can do some corrections or change, so rights protection scope of the present utility model is as the criterion with claims restricted portion.
