Cia peb pib yooj yim.Kev rwb thaiv tsev yog dab tsi?Nws siv qhov twg thiab nws lub hom phiaj yog dab tsi?Raws li Merriam Webster, kom rwb thaiv tsev yog txhais tias "kom cais tawm ntawm kev ua lub cev los ntawm kev siv cov khoom siv hluav taws xob los tiv thaiv kev hloov hluav taws xob, cua sov lossis suab."Rwb thaiv tsev yog siv nyob rau hauv ntau qhov chaw, los ntawm paj rwb rwb thaiv tsev nyob rau hauv lub tsev tshiab lub phab ntsa mus rau lub rwb thaiv tsev lub tsho ntawm cov hlau lead cable.Nyob rau hauv peb cov ntaub ntawv, rwb thaiv tsev yog cov khoom ntawv uas cais cov tooj liab los ntawm cov hlau nyob rau hauv ib tug hluav taws xob lub cev muaj zog.
Lub hom phiaj ntawm qhov sib xyaw ua ke no thiab cov kab sib txuas yog kom cov tooj liab tsis txhob kov cov hlau thiab tuav nws hauv qhov chaw.Yog hais tias cov hlau nplaum tooj liab ntsib cov hlau, cov tooj liab yuav ua rau hauv Circuit Court.Ib tug winding ntawm tooj liab yuav grounding lub system, thiab nws yuav luv luv.Lub cev muaj zog hauv av yuav tsum tau muab tshem tawm thiab rov tsim kho kom rov siv dua.
Cov kauj ruam tom ntej hauv cov txheej txheem no yog kev rwb thaiv tsev ntawm cov theem.Voltage yog ib qho tseem ceeb ntawm cov theem.Tus qauv vaj tse rau qhov hluav taws xob yog 125 Volts, thaum 220 Volts yog qhov hluav taws xob ntawm ntau lub tshuab ziab khaub ncaws.Ob qhov voltages los rau hauv tsev yog ib theem.Cov no tsuas yog ob qho ntawm ntau qhov sib txawv ntawm cov khoom siv hluav taws xob siv hauv kev lag luam hluav taws xob.Ob lub xov hlau tsim ib theem hluav taws xob.Ib qho ntawm cov xov hlau muaj lub zog khiav los ntawm nws, thiab lwm qhov ua haujlwm rau hauv av.Hauv peb-theem lossis polyphase motors, tag nrho cov xov hlau muaj zog.Qee cov thawj voltages siv nyob rau hauv peb-theem hluav taws xob apparatus tshuab yog 208v, 220v, 460v, 575v, 950v, 2300v, 4160v, 7.5kv, thiab 13.8kv.
Thaum winding motors uas yog peb-theem, lub winding yuav tsum tau sib cais ntawm qhov kawg lem raws li coils muab tso rau.Qhov kawg tig los yog coil hau yog cov cheeb tsam ntawm lub cev muaj zog qhov kawg uas cov hlau nplaum hlau tawm ntawm qhov thiab rov nkag mus rau hauv qhov.Phase rwb thaiv tsev yog siv los tiv thaiv cov theem ntawm ib leeg.Phase rwb thaiv tsev tuaj yeem yog cov ntawv hom khoom zoo ib yam li cov khoom siv hauv cov qhov rooj, lossis nws tuaj yeem ua kua roj vanish chav kawm ntaub, los yog cov khoom siv thermal H.Cov khoom no tuaj yeem muaj cov nplaum los yog muaj lub teeb mica plua plav kom nws tsis txhob lo rau nws tus kheej.Cov khoom no yog siv los ua kom cov theem sib txawv ntawm kev kov.Yog tias cov txheej tiv thaiv no tsis tau siv thiab cov theem inadvertently kov, tig los tig luv yuav tshwm sim, thiab lub cev muaj zog yuav tsum tau rov ua dua.
Thaum lub qhov hluav taws xob rwb thaiv tsev tau nkag mus, cov hlau nplaum hlau coils tau muab tso rau, thiab cov theem sib cais tau tsim, lub cev muaj zog yog insulated.Cov txheej txheem hauv qab no yog khi rau qhov kawg lem.Thaum tshav kub kub-shrinkable polyester lacing daim kab xev feem ntau ua tiav cov txheej txheem no los ntawm kev ruaj ntseg cov hlau thiab theem sib cais ntawm qhov kawg lem.Thaum lub lacing tiav lawm, lub cev muaj zog yuav npaj rau kev xaim cov hlau lead.Lacing forms thiab shapes lub taub hau coil kom haum rau hauv lub tswb kawg.Hauv ntau zaus, lub taub hau coil yuav tsum nruj heev kom tsis txhob sib cuag nrog lub tswb kawg.Lub tshav kub-shrinkable daim kab xev pab tuav cov hlau nyob rau hauv qhov chaw.Thaum nws yog rhuab, nws shrinks mus rau ib tug ruaj khov daim ntawv cog lus rau lub coil lub taub hau thiab txo nws txoj kev muaj peev xwm ntawm kev txav.
Thaum cov txheej txheem no npog lub hauv paus ntawm insulating lub tshuab hluav taws xob, nws yog ib qho tseem ceeb kom nco ntsoov txhua lub cev muaj zog sib txawv.Feem ntau, kev koom tes ntau motors muaj kev tsim tshwj xeeb thiab xav tau cov txheej txheem rwb thaiv tsev tshwj xeeb.Mus saib peb cov khoom siv hluav taws xob rwb thaiv tsev kom pom cov khoom hais hauv kab lus no thiab ntau dua!
