Qhov sib txawv ntawm cov cav hloov pauv zaus thiab cov cav zaus kev lag luam

I. Lub cev muaj zog inverter

Cov motors inverter yog cov motorsuas siv thev naus laus zis inverter los tswj qhov ceev ntawm lub cev muaj zog. thev naus laus zis inverter siv cov khoom siv hluav taws xob los tswj qhov ceev ntawm lub cev muaj zog, yog li ua tiav kev tswj hwm qhov ceev, lub zog thiab kev ua haujlwm zoo ntawm lub cev muaj zog.

Lub cev muaj zog hloov pauv zaus los ntawm "lub cev muaj zog zaus tshwj xeeb + lub tshuab hloov pauv zaus" AC tswj kev ceev uas muaj cov khoom siv kho tshuab siab, kev sib xyaw ua ke no tau hloov pauv tag nrho cov kev tswj hwm ceev ceev thiab DC kev tswj hwm ceev; nrog rau kev siv tshuab hluav taws xob fais fab, microelectronics technology, kev txhim kho zoo kawg nkaus ntawm kev siv Nrog rau kev txhim kho zoo kawg nkaus ntawm kev siv tshuab hluav taws xob fais fab, microelectronics technology, kev siv "lub cev muaj zog zaus tshwj xeeb + lub tshuab hloov pauv zaus" ntawm AC hom ceev, nrog nws cov kev ua tau zoo heev thiab kev lag luam, hauv kev tswj hwm ceev kom ua rau hloov pauv ntawm hom ceev ceev ib txwm muaj ntawm tiam tshiab ntawm kev hloov pauv.

Vim yog lub inverter motor tswj thiab tswj tau qhov zoo tshaj plaws, yog li ntawd qib ntawm kev siv tshuab thiab kev tsim khoom tau zoo dua; EPS fais fab mov ua qhov sib txawv yav tom ntej ntawm kev txhim kho inverter thev naus laus zis thiab yog li muaj nws tus kheej tshwj xeeb, tab sis vim yog lub inverter motor system rau kev ua haujlwm ceev lossis qeeb, kev sib hloov ceev ntawm kev teb dynamic thiab lwm yam kev xav tau ntawm lub cev tseem ceeb ntawm lub cev muaj zog hluav taws xob ua lub zog los muab cov kev xav tau hnyav rau lub inverter motor yuav raug coj mus rau lub inverter motor. Hauv electromagnetic, qauv, rwb thaiv tsev thiab lwm yam ntawm kev tsim kho tshiab. Nws tuaj yeem hais tias vim yog qhov zoo tshaj plaws ntawm lub inverter motor hauv kev tswj zaus dua li cov motors ib txwm muaj, txhua qhov chaw siv lub zaus converter peb tsis nyuaj rau pom daim duab ntawm lub inverter motor.

II.Cov Tsav Tsheb Zaus Muaj Zog

Cov cav zaus muaj zog yog hais txog cov cav AC uas tsav ncaj qha siv cov zaus siv hluav taws xob (feem ntau yog 50Hz lossis 60Hz) ua lub zog, thiab feem ntau lawv siv rau hauv qee qhov kev siv uas tsis muaj qhov tseeb, tsis ceev, thiab tsis xav tau ntau. Qhov zoo ntawm cov cav zaus muaj zog yog cov qauv yooj yim, kev ntseeg siab siab thiab tus nqi qis, tab sis qhov tsis zoo yog tias qhov ceev thiab torque nyuaj rau tswj thiab kho, thiab qhov tseeb qis, tsis haum rau cov ntawv thov uas muaj qhov xav tau kev tswj hwm siab.

Hauv kev tsim khoom lag luam niaj hnub no, nrog rau kev txhim kho tas mus li ntawm cov khoom zoo thiab kev ua haujlwm zoo, ntau thiab ntau daim ntawv thov xav tau kev ua haujlwm siab dua thiab kev tswj hwm kev ua tau zoo, yog li lub cev muaj zog inverter tau maj mam hloov lub cev muaj zog zaus kev lag luam ua lub hauv paus. Cov cev muaj zog inverter tuaj yeem tswj qhov ceev thiab lub zog ntawm lub cev muaj zog los ntawm lub converter zaus, txhim kho qhov ua tau zoo thiab qhov tseeb ntawm lub cev muaj zog, thiab tsim nyog rau ntau yam kev siv.

III. Tqhov sib txawv ntawm lub cev muaj zog inverter thiab lub cev muaj zog zaus industrial

Lub cev muaj zog inverter thiab lub cev muaj zog zaus yog qhov sib txawv tseem ceeb tshaj plaws ntawm ob qho kev hloov pauv ntawm lub zog fais fab, qhov voltage thiab zaus ntawm lub cev muaj zog zaus ntawm lub cev muaj zog zaus yog qhov ruaj khov, thaum qhov voltage thiab zaus ntawm lub cev muaj zog inverter hloov pauv, vim yog qhov no, ua rau lub cev muaj zog inverter ua haujlwm tsis zoo, yog li ntawd rau cov yam ntxwv tseem ceeb ntawm lub cev muaj zog, nws yog qhov tsim nyog los ua cov kev ntsuas tsim nyog los tiv thaiv cov txheej txheem ua haujlwm ntawm lub cev muaj zog.

Lub cev muaj zog inverter siv lub inverter, cov zis tawm ntawm lub inverter yog cov duab plaub fab uas tsis yog sinusoidal, cov harmonics siab uas lub inverter tsim tawm muaj feem cuam tshuam ntau dua rau kev ua haujlwm ntawm lub cev muaj zog, cov harmonics siab yuav ua rau lub cev muaj zog siv tooj liab ntawm stator, rotor siv tooj liab, hlau siv thiab kev poob ntxiv nce ntxiv, qhov tseem ceeb tshaj plaws yog kev siv tooj liab ntawm rotor. Vim yog kev poob ntxiv, qhov tshwm sim ncaj qha tshaj plaws yog qhov kub ntawm lub cev muaj zog nce ntxiv.

Vim yog cov laj thawj saum toj no, cov qauv rwb thaiv tsev ntawm lub inverter motor winding piv rau lub cev muaj zog zaus yuav muaj qee qhov sib txawv: qib rwb thaiv tsev ntawm lub inverter motor yuav tsum siab dua li cov motors ib txwm muaj tsawg kawg ib qib, xws li feem ntau ntawm cov motors zaus muaj qib rwb thaiv tsev B, thiab cov motors inverter tsawg kawg raws li qib rwb thaiv tsev F, ntxiv rau qhov sib txawv ntawm cov khoom siv rwb thaiv tsev, cov kab hluav taws xob sib xws kuj yuav muaj qhov sib txawv:

(1) Qib tiv taus cua sov ntawm cov hlau hluav taws xob rau cov inverter motors yuav tsum tau phim nrog cov qauv rwb thaiv tsev ntawm cov windings, thiab xaiv raws li qib tsis tsawg dua 155.

(2) Cov hlau hluav taws xob rau cov inverter motors yuav tsum tau xaiv ua cov hlau hluav taws xob tshwj xeeb, qhov sib txawv ntawm hom hlau hluav taws xob no thiab cov hlau hluav taws xob ib txwm muaj nyob rau hauv qhov tshwj xeeb ntawm cov xim insulating, uas tuaj yeem zam qhov tshwm sim ntawm kev tso tawm thiab qhov teeb meem ntawm kev cua sov ntawm cov khoom siv insulating, uas tuaj yeem lav qhov kev ua haujlwm zoo ntawmcov cav inverterthiab ua kom lub neej ua haujlwm ntawm cov motors ntev dua.

Hauv daim ntawv thov tiag tiag, qee lub tuam txhab tsim lub cev muaj zog hauv lub tshuab inverter motor winding nrog cov hlau nplaum electromagnetic tuab, tuaj yeem txo qhov ua rau muaj qhov yuam kev winding, tab sis tsis tuaj yeem daws qhov teeb meem tseem ceeb. Yog li, los ntawm kev tshuaj xyuas cov yam ntxwv tseem ceeb ntawm lub cev muaj zog inverter, kev siv cov hlau nplaum electromagnetic tshwj xeeb inverter, tuaj yeem daws qhov kub tsis kam thiab tiv thaiv qhov tshwm sim ntawm cov teeb meem corona.
