See motor 300 below again, as shown in Figure 3, through terminal board X1, circuit breaker Q, protector FS and A.C. contactor K1, K2 motor 300 is supplied power successively by the three phase mains of transformer 100 outputs.Realize the running of motor by the break-make of A.C. contactor K1, K2 as previously mentioned and stop.When the K1 closure was connected, motor power voltage was 380V, the motor corner connection; When the K2 closure was connected, motor power voltage was 660V, and the motor star connects.
About the automatic switchover of the mode of connection of motor winding, please 4a with the aid of pictures and specific embodiment of Fig. 4 b the utility model in the circuit diagram of motor winding.When transformer 100 output voltages (being motor 300 input voltages) were 660V, the motor winding automatically switched to star and connects, and sees Fig. 4 a; When transformer 100 output voltages (being motor 300 input voltages) were 380V, the motor winding automatically switched to corner connection, sees Fig. 4 b.Guarantee that the power output of motor 300 is identical under two kinds of electric pressures.
Have the identical ability that drags explanation about motor under above-mentioned two kinds of electric pressures:
Output power of motor
P = 3 U 2 R ,
In the formula: P---output power of motor,
U---phase voltage,
R---motor winding resistance,
The transformer output voltage is a line voltage; The voltage at motor winding two ends is phase voltage.
When the transformer output voltage is 660V, see Fig. 4 a, motor winding star connects, and the phase voltage that is applied to motor winding R two ends does
660 1.732 = 380 ( V ) ;
When the transformer output voltage is 380V, see Fig. 4 b, the corner connection of motor winding, the phase voltage that is applied to motor winding two ends equals line voltage, also is 380V.Because the R value is constant, phase voltage U is also constant, so output power of motor is also constant.
To sum up; The anti-electricity-theft oil pumper dragging system of the automatic Regulation of the utility model has the function to motor, the synchronous switch operating voltage of transformer; Can under 380V or the arbitrary voltage of 660V, move; Also can will export 380V, 660V voltage according to the time cycle circulation of setting two kinds of alternating voltage periodic duties, the cycle is can set arbitrarily in 10 minutes to 24 hours; Because of output voltage no longer is fixed value so can effectively stop the generation of stealing electricity phenomenon.
It should be noted that the foregoing description is example and unrestricted the utility model, those skilled in the art can design a lot of alternate embodiments and not break away from the scope of claims.
