Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done to describe in further detail.
As shown in Figure 1, the utility model stirring motor protective device, comprise casing 1, described casing front panel is provided with electric motor protecting state display window to change mouth 11, three-phase power socket 12, electric motor starting button SB1 and motor stop button SB2, as shown in Figure 2, be provided with microcomputer electric motor protector 2 in the described casing 1; The model of described microcomputer electric motor protector 2 is JL-200, described microcomputer electric motor protector 2 includes two power supply terminals, two Chang Kaiduan and two normally closed terminals, is provided with a fuse FU between the terminal L3 among two power supply terminal N, L of described microcomputer electric motor protector 2 and three phase mains input terminal L1, L2, the L3; Be parallel with a branch road with described microcomputer electric motor protector 2, one end of described branch road is to be connected with the first A.C. contactor KM1 with described electric motor starting button SB1, motor stop button SB2 successively from described fuse FU, and the described first A.C. contactor KM1 is connected to a normally-closed contact 95 of described microcomputer electric motor protector 2; Another normally-closed contact 96 ground connection are parallel with the second A.C. contactor KM2 with described motor stop button SB2; Be provided with the 3rd A.C. contactor KM3 between terminal U, the V of three phase electric machine M ~ 3, W and three phase mains input terminal L1, L2, the L3.
During use, the plug of can directly motor being powered inserts the consumer unit socket, and is extremely easy to use.In the three phase electric machine operation process; during if break down; two normally-closed contacts 95,96 of microcomputer electric motor protector JL-200 inside disconnect; cut off the power supply of the first A.C. contactor KM1 wire loop; make first A.C. contactor KM1 holder button; and then cut off the motor current supply circuit, motor is played protective effect timely.Microcomputer electric motor protector 2 need carry out hand-reset to it after the protection action takes place.Have reset button on microcomputer electric motor protector 2 guidance panels, two normally-closed contacts 95,96 of the microcomputer electric motor protector 2JL-200 inside, back that resets revert to normally closed by disconnection again.Cause that microcomputer electric motor protector 2 takes place to protect the factor of action not eliminate, even press reset button, described microcomputer electric motor protector 2 also can't revert to normal operating condition, thus the danger of having avoided possibility to take place owing to misoperation.
