The utility model adopts whole bi-motor and the automatic distribution control box of two-shipper to form.The main auxiliary machine gross power satisfies the requirement of electromotor heavy load startup and pulsation heavy load, and the power configuration of main frame satisfies the motor actual loading.And start constantly from electrical power, motor operation overall process is implemented monitoring and control.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
KQ1 is the three-phase air switch among the figure, and CJ1, CJ2 are the A.C. contactor of main auxiliary machine, and DB1 is a controller power supply.HT1, HT2 are a punching instrument transformer, and M1 and M2 are whole bi-motor, and YY1-11 is automatic control and protector, and DB1 is a controller power supply.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, the utility model comprises automatic control and protector YY1-11, three-phase air switch KQ1 and 2 A.C. contactor CJ1, CJ2,2 punching instrument transformer HT1, HT2 and working power.Its controlling object is whole bi-motor, includes a main motor M 1 and an auxiliary motor M2.Main motor M 1, the auxiliary motor M2 of whole bi-motor also connects the back and is connected in the working power (not shown) by three-phase air switch KQ1, is connected with A.C. contactor CJ1 (CJ1-1, CJ1-2 and CJ1-3), a punching instrument transformer HT1 on the operating circuit between main motor M 1 and the three-phase air switch KQ1 in turn.Be connected with A.C. contactor CJ2 (CJ2-1, CJ2-2 and CJ2-3), a punching instrument transformer HT2 in turn on the auxiliary motor M2 of whole bi-motor and the operating circuit between the three-phase air switch KQ1.The detection output signal end of a punching instrument transformer HT1 (c, b, a, H, G, O) correspondence is connected in the input (c1, b1, a1, H1, G1, O1 pin) of automatic control and protector YY1-11, and the detection output signal end of a punching instrument transformer HT2 (H, G, O) correspondence is connected in the input (H2, G2, O2 pin) of automatic control and protector YY1-11.W circuit in motor M 1, the M2 three-phase circuit is connected to L1, the L2 pin of automatic control and protector YY1-11, to finish jointly motor M 1, M2 real work current signals with punching instrument transformer HT1, a HT2.The utility model also includes control executive circuit L; this control executive circuit L is connected in the outlet line of three-phase air switch KQ1 by circuit 1,2, by providing working power (providing the 24V operating voltage by circuit 17,18) to automatic control and protector YY1-11 after the transformer transformation.The control of the controlled executive circuit L of A.C. contactor CJ1, CJ2; automatic control and protector YY1-11 are connected in the access point 6,9,7 and 10 of this control executive circuit L by J1, J2 mouth; control adhesive and the disconnection of A.C. contactor CJ1, CJ2, whole bi-motor M1 and M2 are switched on or cut off the power supply.
The course of work of the present utility model is: at first CJ1 adhesive conducting after KQ1 closes a floodgate, M1 operation; HT1 exports to YY1-11 with the conduction of actual sensed current signal simultaneously, and YY1-11 responds according to input signal in good time: CJ2 adhesive M2 starts when the M1 overload starts then; At M1, in the M2 running, YY1-11 will control and disconnect CJ2 when the actual motion electric current of M1 satisfies its rated current, and M2 withdraws from.If the load change surpasses the M1 load greatly and continuously in the M1 isolated operation process, YY1-11 will control the CJ2 adhesive, and M2 starts, and CJ2 disconnects in case the load continous-stable is reduced to the M1 nominal load, and M2 withdraws from.The utility model smoothly starts main auxiliary machine by the real-time monitoring to the operation overall process of whole bi-motor step by step thus, and the needs according to actual loading make subsidiary engine incision and out of service automatically, have so not only solved the difficulty of motor start-up but also make motor efficiently operation all the time.
