Abstract
The utility model relates to a motor, particularly a 155KW /130KW three-phase asynchronous homopolar double-load motor, which is composed of a stator of the motor, the number of slots, the number of poles, etc. The motor adopts an octopole four-way Y connection mode during high load and an octopole two-way delta connection mode during low load. The motor can reduce electric power consumption between 27 % and 31% during low load as compared with the situation of full load.
Description
The utility model relates to a kind of motor, the two load motors of the phase asynchronous homopolarity of particularly a kind of 155KW/130KW.
At present, many AC asynchronous motor with load with the variation of operating mode very big variation is arranged, selecting for use all of motor capacity decided with maximum load, when if the motor running load is less, its efficient and power factor are all corresponding to be reduced, increase the motor cost of use, increased line loss, reduced the utilance of electrical network.
The purpose of this utility model is to provide the 155KW/130KW AC asynchronous motor of efficient, the High Power Factor of two kinds of loads of a kind of suitable height.
The utility model is to realize (seeing Fig. 1, Fig. 2, Fig. 3) like this.It is made up of motor stator, groove number and number of poles etc., according to motor stator slot number and motor pole number, suitably increase the lead-out wire of stator coil to line outlet, change the series and parallel way and the connection of coil of stator of motor by the lead-out wire of change at motor line outlet place, when the motor operating load is high, with the mode of connection (see figure 2) of the ends of the earth four road Y, when the motor operating load is low, with the mode of connection (see figure 3) of the ends of the earth two road △.
Fig. 1 is a stator elementary diagram of the present utility model
Winding diagram when Fig. 2 is a stator high load capacity of the present utility model
Winding diagram when Fig. 3 is a stator underload of the present utility model
Below in conjunction with accompanying drawing the utility model is described in further detail:
The utility model 155KW/130KW is phase asynchronous to be per two winding parallel connections with the method for attachment of establishing two load motor tap (seeing Fig. 1,2,3) taps, during high load capacity, mode of connection (see figure 2), binding post 2,6,10,4,7,12 with the ends of the earth four road Y, binding post 1,3, binding post 5,8, binding post 9,11 links to each other with lead respectively, and binding post 9,5,1 links with three phase mains respectively again.During underload, with the mode of connection (see figure 3) of eight grade of two road △, with binding post 2,3, binding post 6,8, binding post 10,11, binding post 1,7, binding post 5,12, binding post 9,4 link to each other with lead respectively, and binding post 9,5,1 links with three-phase power line respectively again.This motor underload reduces 27～32% of power consumption during than high load capacity.
