Abstract
The invention discloses a fault simulation assessment device of a three-phase asynchronous motor. The fault simulation assessment device is of a cabinet structure, and comprises a power module, a fault detection module, a fault setting module and a fault clearing module, the power module is an independent module and is used for providing 380V three-phase alternating current, the fault detection module is used for being connected with an external three-phase motor, the fault setting module is used for teachers to set faults, the fault clearing module is used for students to clear faults, and the fault detection module, the fault setting module and the fault clearing module are connected via leads in a one-to-one correspondence manner so as to achieve assessment of the students on fault judgment of the three-phase asynchronous motor. In a teaching process, the teachers can preset faults, and the students can judge and clear the faults by the aid of a multimeter and a megohm meter. Student capabilities of quickly judging, overhauling and clearing common faults of the three-phase asynchronous motor are improved, and requirements, of higher vocational colleges and unit training institutions, on middle-level and high-level assessment of maintenance electricians are met.
Description
Technical field
The present invention relates to a kind of fault simulation checking device of threephase asynchronous.
Background technology
Threephase asynchronous in use various faults can occur, normally moves in order to ensure the safety of threephase asynchronous, after motor breaks down, must investigate thoroughly quickly and accurately the reason that fault occurs, in order to repair as early as possible.In teaching process, can't accomplish in real threephase asynchronous machine inside, different faults to be set, have a strong impact on the study of student aspect the fault judgement of threephase asynchronous, investigation, maintenance.Thereby, in the urgent need to developing a kind of fault simulation checking device of threephase asynchronous machine, can simulate the fault of threephase asynchronous machine, improve the ability of student's fault judgement aspect threephase asynchronous machine, investigation, maintenance aspect.
Summary of the invention
The present invention is directed to existing deficiency, a kind of fault simulation checking device of threephase asynchronous is provided, can improve the ability of student malfunction elimination aspect aspect threephase asynchronous machine.For achieving the above object, the present invention adopts technical scheme to be:
A kind of fault simulation checking device of threephase asynchronous, it is cabinet type structure, comprises
Power module is used for providing the 380V three-phase alternating current;
Fault detection module is used for being connected with the three phase electric machine of outside;
Fault arranges module, is used for the teacher fault is set;
Fault is got rid of module, is used for the student and fixes a breakdown;
Described power module is standalone module, and fault detection module, fault arrange between module and fault eliminating module and connect one to one with wire, to realize that the student is to the examination of threephase asynchronous fault judgement.
Be embedded with power module, fault detection module, fault eliminating module on the front panel of described cabinet type structure, be embedded with fault on described cabinet type structure side panel module is set.Described fault arrange module can simulate arrange that threephase asynchronous phase shortage, winding open circuit, turn-to-turn short circuit, phase fault or leak current fault, described fault arranges module and is coated with cover plate.
The invention has the beneficial effects as follows: in teaching process, the teacher can preset fault in the present invention, the student can judge and get rid of this fault by multimeter and megger, improve the student and judge fast, overhaul, get rid of threephase asynchronous most common failure ability, and satisfy each School of High Profession Technology and constituent parts training organization is intermediate as the maintenance electrician, senior examination needs.
