Description of drawings
Fig. 1 is the schematic diagram of voltage and speed regulating controller for single-phase asynchronous motor.
Embodiment
For the ease of introducing content of the present invention, below the applicant by introducing the speed control principle that the application of voltage and speed regulating controller for single-phase asynchronous motor in air-conditioning system illustrates the single-phase asynchronous motor speed setting controller.
A kind of air conditioner comprises indoor set, off-premises station, and described indoor set includes a blower fan, and described air conditioner also comprises a blower fan variable voltage control controller.As shown in Figure 1, described blower fan variable voltage control controller is made up of following components: dial-up setting section 1, transformation rectification circuit 2, power supply zero-detection circuit 3, thyristor operating angle regulating circuit 4, controllable silicon drive circuit 5.Described variable voltage control controller is regulated silicon controlled conducting angle by the triggered time of 555 timers of adjusting thyristor operating angle regulating circuit 4, utilize the chopper circuit principle to adjust the blower fan driving voltage, thereby regulate the blower fan wind speed, realize stepless speed regulation truly.It is 150V that while variable voltage control controller has been set the pressure regulation minimum, has guaranteed that air-conditioning system under the situation of low wind speed operation, can not enter protection because of system pressure changes, and promptly guarantee the reliability service of air-conditioning system.
The user is when using this controller, and the toggle switch by dial-up setting section 1 comes setting controller whether speed-regulating function is arranged.If select to have speed-regulating function, after the single-phase 220V AC power input, through being input to rectification circuit after the transformer transformation, described rectification circuit is simple diode bridge rectifier circuit, to carrying out rectification, be sent to power supply zero-detection circuit 3 after the rectification through the single phase poaer supply after the transformation.Power supply zero-detection circuit 3 is made of photoelectric isolating circuit, the zero point in the time of can accurately detecting voltage fluctuation, and with zero point pulse signal be delivered to thyristor operating angle regulating circuit 4.Thyristor operating angle regulating circuit 4 is made up of 555 timers, charging capacitor, trigger triode and rotational potentiometer.The charging circuit that charging capacitor and rotational potentiometer constitute provides base voltage for trigger triode, the trigger triode conducting, thus triggering 555 timers, 555 timers provide enough big electric current, voltage signal to controllable silicon drive circuit 5.Controllable silicon drive circuit 5 is made up of gate trigger circuit and controllable silicon.Described gate trigger circuit has adopted RC circuit in parallel, to keep silicon controlled voltage change ratio and current changing rate in suitable scope, and can be by false triggering, conducting reliably simultaneously, it receives the controllable silicon drive signal from the thyristor operating angle regulating circuit, the conducting controllable silicon provides operating voltage to inner blower.
The pulse signal at zero point that produces through photoelectric isolating circuit passes on the pin of rotational potentiometer, and the user changes the base voltage of trigger triode by the resistance of regulating rotational potentiometer, thereby changes the triggered time of 555 timers.555 timer output signals trigger the controllable silicon gate pole, change the triggering signal that is input to the gate pole circuit by the triggered time that changes 555 timers, thereby change silicon controlled conducting angle, utilize the chopper circuit principle, thereby the drive end voltage of having adjusted inner blower is to reach the purpose of speed governing.
If the user selects setting controller not have the speed regulating control function, promptly whole controllable silicon driver module is not worked, and total head output drives inner blower.
The present invention is an example by the speed regulating control with the air conditioner inner blower, has introduced the speed control principle of voltage and speed regulating controller for single-phase asynchronous motor, and this can not be considered to the restriction to claim of the present invention.If those skilled in the art has made change unsubstantiality, conspicuous or improvement according to the present invention, all should belong to the scope of claim protection of the present invention.
