Lub luv luv Circuit Court tshwm sim ntawm lem nyob rau hauv lub motor windings

 

Yog hais tias ib tug luv luv Circuit Court tshwm sim ntawm lem nyob rau hauv lub motor winding, cov nram qab no phenomena yuav tshwm sim.

1) Lub luv luv-circuited kauj yuav ntws los ntawm lub voj voog loj tam sim no (feem ntau 2-10 zaus tam sim no), ua rau lub kauj kub kub heev;

2) Peb-theem tam sim no tsis sib npaug, thiab lub cev muaj zog torque raug txo:

3) Ua suab nrov;

4) Thaum lub caij luv luv luv, lub cev muaj zog tsis tuaj yeem pib nrog lub nra.

 

Inter-tig luv luv Circuit Court: Thaum pib, tsuas yog ob lub xov hlau tuaj yeem nkag mus rau hauv kev sib cuag vim yog rwb thaiv tsev ntawm qhov sib tshooj.

Vim lub voj voog tsim nyob rau hauv luv luv Circuit Court tig, lub kauj heats sai sai, ntxiv kev puas tsuaj rau lub rwb thaiv tsev ntawm cov hlau uas nyob ib sab, yog li ntawd tus naj npawb ntawm lem ntawm luv luv Circuit Court txuas ntxiv mus thiab qhov txhaum expands.

 

Thaum tus naj npawb ntawm luv Circuit Court lem txaus, lub fuse yuav raug hlawv, thiab txawm tias lub winding yuav scorched thiab haus luam yeeb, thaum peb-theem winding muaj ib theem ntawm inter-tig luv Circuit Court, nws yog sib npaug rau cov theem winding cov lem txo, lub stator peb-theem tam sim no yog unbalanced. Peb-theem tam sim no ntawm txoj kev tsis sib xws ua rau lub cev muaj zog vibrate, thiab tib lub sij hawm emits lub suab txawv txav-pov thawj huab platform.

 

Qhov nruab nrab torque ntawm lub cev muaj zog poob qis, thiab nws zoo li tsis muaj zog thaum rub lub load.

 

Qhov ua rau luv luv Circuit Court ntawm lem ntawm lub cev muaj zog winding

 

1) Kev tsim khoom tsis zoo. Piv txwv li: kev puas tsuaj rau lub rwb thaiv tsev inter-tig nyob rau hauv cov txheej txheem ntawm off-line, shaping thiab lwm yam txheej txheem: tooj liab hlau muaj zog blocks thiab burrs, uas yuav ua rau inter-tig rwb thaiv tsev puas.

2) Thaum lub sijhawm ua haujlwm, nyob rau hauv qhov kev txiav txim ntawm hluav taws xob, thermal thiab txhua yam kev ntxhov siab, cov windings yog deformed thiab hloov chaw, ua rau tawg, hnav thiab poob ntawm lub rwb thaiv tsev ntawm lem: ntxiv rau, vim av, thiab lwm yam, nws kuj yuav ua rau luv luv Circuit Court ntawm lem (tshwj xeeb tshaj yog nruab nrab ntawm qhov kawg ntawm lub rotor winding).

3) Kev khiav hauj lwm ntev thiab kev laus rwb thaiv tsev kuj yuav ua rau luv luv Circuit Court ntawm lem.

 

Lub cev muaj zog winding inter-tig luv Circuit Court kho txoj kev

 

Thaum lub luv luv Circuit Court tshwm sim nyob rau hauv lub winding, nws yuav feem ntau yog manifested raws li ib tug fuse ntawm lub cev muaj zog fais fab mov Circuit Court los yog ib qho kev mus ncig ntawm lub hloov; Thaum lub cev muaj zog winding yog luv-circuited, ib tug loj tam sim no generated thiab lub kauj heats sai sai thiab burns tawm. Yog li ntawd yuav muaj qhov kub hnyiab; tsis sib npaug ntawm cov hlau nplaum; Qhov tsis txaus ntseeg tam sim no ua rau lub cev muaj zog vibrate lossis ua rau lub suab nrov nrov thaum lub sijhawm ua haujlwm, thiab tseem ua rau lub cev muaj zog tsis tuaj yeem ua haujlwm li qub. Nyob rau hauv qhov kev tshwm sim ntawm ib tug luv luv Circuit Court, peb yuav daws tau nws los ntawm cov nram qab no txoj kev

 

1. Induction method >>

 

Txoj kev no yog siv lub hauv paus ntsiab lus ntawm electromagnetic induction los muab ib qho tshwj xeeb luv luv-circuit transformer-luv-circuit detector thoob plaws stator nce, tom qab lub luv-circuit detector yog energized, yog hais tias cov hlau ntawv muab tso rau hauv notch vibrates, nws txhais tau hais tias muaj ib tug luv luv Circuit Court tshwm sim.

 

2 Observational >>

Ntawd yog, saib seb qhov kawg ntawm cov winding thiab cov rwb thaiv tsev hauv lub cev puas raug puas los yog hlawv, thiab seb puas muaj ntxhiab tsw tsw.

 

3 multimeter or megohmmeter inspection method >>

Ntawd yog, siv ob lub rooj no los ntsuas cov rwb thaiv tsev tiv thaiv ntawm ob-theem winding, thiab kev nyeem ntawv tsawg heev lossis xoom, ces muaj ib theem-rau-theem luv luv Circuit Court.

 

4. Detection temperature check method >>

Ua kom lub cev muaj zog khiav tsis muaj kev thauj khoom rau qee lub sijhawm, thiab kov qhov kub ntawm txhua qhov ntawm winding los ntawm txhais tes txawm tias nws zoo li qub, yog tias muaj luv luv Circuit Court ntawm lem, ces qhov kub ntawm qhov chaw no feem ntau yuav siab heev.

 

5 Energization test method >>

Qhov no yog ib txoj hauv kev yooj yim, uas yog, sim nrog lub ntsuas tam sim no, yog tias muaj qhov luv luv ntawm cov theem, qhov tam sim no los ntawm feem ntau kuj loj. Cov saum toj no yog ntau txoj kev kho mob, thiab peb piav qhia lawv nrog cov piv txwv hauv qab no.

 

Thaum lub voj voog luv luv tshwm sim, cov txheej txheem yuav tsum tau tshuaj xyuas raws li qhov xwm txheej tiag tiag thiab cov kev ntsuas sib raug yuav tsum tau coj los daws nws.
