Abstract
The present invention relates to a domestic miniature diving pump electromotor of two phase or three phase electricity, which belongs to the technical field of a usual miniature electromotor. The principle of a single or three phase dual-purpose electromotor is to modify the original three phase electromotor into a single phase electromotor without rewinding windings, star connection or triangle connection type is used to provide a miniature diving pump electromotor which can be used in two phase and three phase electricity, and thus, the used cost of the electromotor and the safety performance are reduced.
Description
Technical field
The present invention relates to a kind of home motor, the present invention relates to a kind of domestic miniature motor for submerged pump that can be used for two-phase or three-phase electricity more precisely.Belong to micromotor technical field commonly used.
Background technology
At present; the rural area common people aspect water or small town citizen aspect water; often can use small-sized motor for submerged pump; but these motors generally all are two-phase electricity or three-phase electricity separately to be used; the two cannot use alternately, in case when having only two-phase motor or having only threephase motor, but have only three-phase or two-phase; at this moment motor just can not finely use, and the general people's of problem solution is two motors that have two-phase and three-phase simultaneously hereto.Do so on the one hand and improved financial burden, preserve also cumbersome on the other hand.And people are not very safe on the one hand if transform simply, are difficult on the other hand change yet.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, provide a kind of and both can on the two-phase electricity, use the miniature submersible pump electric motor that also can on three-phase electricity, use safely, thereby reduced cost and the security performance that people use motor.
The present invention takes following technical scheme to realize:
Two-purpose miniature submersible pump electric motor of single or three phases comprises one of three-phase ac contactor, two of two-phase A.C. contactors, one of threephase switch, one on two-phase switch, two of push-button switches, at least one in capacitor, micro pump or motor; Its connected mode connects motor down- lead line tail 4,5,6 the end of a thread for first A.C. contactor C1 goes up pile crown, 380 volts of power supply threephase switch DK1 are connected in parallel, following pile crown connects motor down-lead the end of a thread 1,2,3 the end of a thread, and the following pile crown of second the A.C. contactor C2 that be connected in parallel, coil connect 220 volts of power supplys; Second A.C. contactor C2 goes up pile crown and is connected in parallel; The 3rd A.C. contactor C3 goes up pile crown and meets 220 volts of power supply two-phase switch DK2, following pile crown connects wherein two lines in motor down-lead the end of a thread 1,2,3 the end of a thread, the 3rd another following pile crown of A.C. contactor C3 connects capacitor C, and another joint of capacitor C connects motor lines lead-in wire the end of a thread 1,2,3 one of them joint of the end of a thread; 380 volts of one of button switch K K1 connect 380 volts of power supplys, and the other end connects the coil of second A.C. contactor C2, and second A.C. contactor C2 coil other end connects 380 volts of power supplys; 220 volts of one of button switch K K2 connect 220 volts of power supplys, and the other end connects the coil of the 3rd A.C. contactor C3, and the 3rd A.C. contactor C3 coil other end connects 220 volts of power supplys.
During with 380 volts, the leading-out end of motor down-lead the end of a thread 1,2,3 is connected in parallel, and motor down- lead line tail 4,5, the 6 logical power supplys of going up at this moment without capacitor, are connected into star connection to motor.During with 220 volts, by first A.C. contactor C1, the 3rd A.C. contactor C3 motor is connected into delta connection, lead-in wire 1 is connected with 6, goes between 2 to be connected with 4, lead-in wire 3 is connected with 5, and capacitor is connected in parallel in two wire terminals choosing wantonly of motor down-lead the end of a thread 1,2,3.
Single three-phase dual-purpose motor principle is original three phase electric machine to be changed into monophase machine use, need not recoil winding, the monophase machine principle is told us: two windings in space mutual deviation 90 degree electrical degrees, the magnetic flux axis that winding produces is also mutual deviation 90 degree electrical degrees in the space, just produce the two-phase rotating magnetic field by electric current again, make electric motor starting thereby can produce starting torque with out of phase.It is by circuit connecting mode that three phase electric machine changes monophase machine into, and it is connect to using three-phase (380 volts) voltage also can use in single-phase (220 volts) voltage.Three-phase miniature water pump or power of motor 3KW with interior all be star connection, if must be connected into delta connection when using single-phase 220 volts of voltages.Because exist two kinds of voltages in the three-phase circuit of Y-connection, a kind of is voltage between every phase two ends, be voltage between phase line and the zero line phase voltage V phase, another kind be voltage between per two phase lines on line voltage V line, the relation between line voltage and the phase voltage is
Relation between line current and the phase current is I line=I phase, as shown in Figure 2:
In the circuit that triangle connects, the line voltage of the alternating current of per two phase lines and phase voltage equate that promptly V line=V phase does not still wait at this connection current in middle wire and phase current, and relation is
See Fig. 3.
This shows that when using three-phase (380 volts) voltage, the threephase switch DK1 that closes presses the button K switch K1, at this moment three-phase ac contactor C2 adhesive.Motor down-lead the end of a thread 1,2,3 is linked together, and motor down- lead line tail 4,5,6 is made power line, and entire circuit is connected into star connection, and at this moment motor just gets into smooth.When using single-phase 220 volts of voltages, the two-phase of closing switch DK2 presses the button K switch K2, at this moment first exchanges tentaculum C1, the 3rd A.C. contactor C3 adhesive simultaneously, motor windings is connected into delta connection, shown in Figure 1 as pressing, any one common winding as monophase machine, two-phase is main winding and auxiliary winding in addition.One or several operation capacitors respectively in parallel between the major-minor winding, 2KW with interior can be without start capapcitor, the size of capacitor is calculated according to the power of motor size, if counter-rotating can be exchanged the major-minor winding once gets final product.Just motor to be connected into single three-phase dual-purpose for connection different modes by circuit like this.After being connected into monophase machine, power is 0.8-0.9 times of original three phase power.It is littler than monophase machine no-load current and full-load current, and this machine major-minor winding coil, line warp, the number of turn be size equally, can not burn out auxiliary winding during use, and heavily fortified point is durable for a long time, saves electric energy, and long service life is a kind of novel energy-conserving product.
