Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1: the present invention includes the first resistance R1, second resistance R2, 3rd resistance R3, slide rheostat W, first electric capacity C1, second electric capacity C2, bidirectional thyristor KS and neon tube TD, the first end of bidirectional thyristor KS simultaneously with the first end of the second resistance R2, the first end of the first resistance R1 is connected with the first end of the motor M of refiner, second end of bidirectional thyristor KS simultaneously with the first end of the second electric capacity C2, the first end of the first electric capacity C1 is connected with one end of AC power, second end of the second resistance R2 is connected with second end of the second electric capacity C2, the control end of bidirectional thyristor KS is connected with the first end of the 3rd resistance R3, second end of the 3rd resistance R3 is connected with the first end of neon tube TD, second end of neon tube TD simultaneously with the sliding end of slide rheostat W, the first end of slide rheostat W is connected with second end of the first electric capacity C1, second end of slide rheostat W is connected with second end of the first resistance R1, second end of the motor M of refiner is connected with the other end of AC power.
As shown in Figure 1: the present invention utilizes bidirectional thyristor KS on-line operation in AC power, regulate the second resistance R2 can control the angle of flow of bidirectional thyristor at positive and negative two half cycles of power supply, reach the object of the motor M rotating speed changing refiner with the input voltage of the motor M changing refiner.TD in figure is general neon tube, and on electrical property, it is similar to two-way silicon trigger tube, and trigger power is large.In addition, it can also be used as indicator light, is a kind of trigger tube of inexpensive dual-use material.Second resistance R2 and the second electric capacity C2 is arranged in order to over-voltage suppression.
As shown in Figure 1: after switching on power, supply voltage is by the first resistance R1, and the second resistance R2 charges to the first electric capacity C1, after the peak value of the voltage at the first electric capacity C1 two ends reaches the blocking voltage of neon tube TD, neon tube TD is bright, the conducting thus bidirectional thyristor KS is triggered.The size of bidirectional thyristor KS Trigger Angle controls by changing first electric capacity C1 charging interval Changshu.Just can control bidirectional thyristor KS by the size changing the second resistance R2 to trigger in any phase place.If the second resistance R2 is too large; by the situation making the first electric capacity C1 both end voltage reach curve decline; now the voltage rise at the first electric capacity C1 two ends obtains slowly; may make the voltage at the first electric capacity C1 two ends between whole mains half-cycle; the blocking voltage of neon tube TD cannot be reached; namely bidirectional thyristor KS can not conducting; that is some limiting values are had with changing when slide rheostat W controls the brightness of the motor M rotating speed of refiner or neon tube TD, then uncontrollable lower than this limiting value.Therefore, when slide rheostat W is greater than limiting value, the first resistance R1 and the first electric capacity C1 can be adopted to help the first electric capacity C1 both end voltage and to rise, make it reach the blocking voltage of neon tube TD, to trigger bidirectional thyristor KS.It can thus be appreciated that slide rheostat W is used to the average current of control load.
