- Inverter lub cev muaj zog
Inverter motors yog cov motors uas siv cov tshuab inverter los tswj qhov ceev ntawm lub cev muaj zog. Inverter technology siv cov khoom siv hluav taws xob los tswj kev ceev ntawm lub cev muaj zog, yog li paub txog kev tswj lub cev muaj zog, lub zog thiab kev ua haujlwm zoo.
zaus hloov lub cev muaj zog los ntawm "tshwj xeeb zaus induction lub cev muaj zog + zaus converter" AC ceev tswj txoj kev tsim los ntawm cov qib siab ntawm cov tshuab automation ntawm cov khoom siv lub cev muaj zog, qhov kev sib xyaw ua ke no tau hloov tag nrho cov txheej txheem tswj kev ceev thiab DC ceev tswj kev pab cuam; Nrog lub zog hluav taws xob siv tshuab, microelectronics thev naus laus zis, kev txhim kho zoo heev ntawm kev siv Nrog kev txhim kho zoo ntawm lub zog hluav taws xob tshuab hluav taws xob, microelectronics thev naus laus zis, kev siv "tshwj xeeb zaus induction lub cev muaj zog + zaus hloov pauv" ntawm AC ceev hom, nrog nws cov kev ua tau zoo thiab kev lag luam, nyob rau hauv kev tswj ceev kom ua tau ib qho kev hloov ntawm cov tsoos ceev hom kev hloov tshiab tiam.
Vim lub inverter lub cev muaj zog ceev tswj thiab tswj ntawm qhov tsis sib xws superiority, thiaj li hais tias cov degree ntawm mechanical automation thiab productivity zoo heev; EPS fais fab mov raws li cov qauv yav tom ntej ntawm kev txhim kho ntawm inverter technology thiab yog li nws muaj nws tus kheej tshwj xeeb, tab sis vim yog lub inverter lub cev muaj zog rau kev ua haujlwm siab lossis qis qis, kev sib hloov ceev ntawm cov lus teb dynamic thiab lwm yam kev xav tau ntawm lub cev tseem ceeb ntawm lub tshuab hluav taws xob raws li lub zog los muab cov kev xav tau hnyav yuav muab rau lub inverter lub cev muaj zog. Nyob rau hauv electromagnetic, qauv, rwb thaiv tsev thiab lwm yam ntawm innovation. Nws tuaj yeem hais tias vim qhov zoo tshaj plaws ntawm lub cev muaj zog inverter hauv kev tswj hwm zaus ntawm cov motors zoo tib yam, txhua qhov chaw siv zaus hloov pauv peb tsis yooj yim pom cov duab ntawm lub inverter lub cev muaj zog.
- Industrial Frequency Motors
Muaj zaus lub cev muaj zog xa mus rau AC motors uas tau tsav ncaj qha los ntawm kev siv hluav taws xob zaus (feem ntau yog 50Hz lossis 60Hz) raws li lub zog hluav taws xob, thiab lawv feem ntau yog siv rau hauv qee qhov kev siv qis, qis qis, thiab kev thov qis. Qhov zoo ntawm kev lag luam zaus motors yog cov qauv yooj yim, muaj kev ntseeg siab thiab tus nqi qis, tab sis qhov tsis zoo yog tias qhov ceev thiab lub zog yog qhov nyuaj rau kev tswj thiab kho, thiab qhov tseeb yog qhov tsawg, tsis haum rau cov ntawv thov uas muaj kev tswj xyuas siab.
Hauv kev lag luam niaj hnub no, nrog kev txhim kho tas li ntawm cov khoom lag luam zoo thiab cov kev xav tau ntawm kev ua haujlwm, ntau thiab ntau daim ntawv thov yuav tsum tau siab dua precision thiab tswj kev ua tau zoo, yog li lub inverter lub cev muaj zog tau maj mam hloov lub tshuab muaj zaus raws li lub ntsiab. Inverter motors tuaj yeem tswj qhov ceev thiab lub zog ntawm lub cev muaj zog los ntawm kev hloov pauv zaus, txhim kho qhov ua tau zoo thiab qhov tseeb ntawm lub cev muaj zog, thiab tsim nyog rau ntau yam kev siv.
- Qhov txawv ntawm inverter lub cev muaj zog thiab muaj zaus lub cev muaj zog
Inverter lub cev muaj zog thiab muaj zaus lub cev muaj zog yog qhov tseem ceeb tshaj qhov sib txawv ntawm ob lub zog hloov pauv, kev lag luam zaus lub cev muaj zog input voltage thiab zaus yog qhov tsis tu ncua, thaum lub input voltage thiab zaus ntawm lub inverter lub cev muaj zog hloov, yog vim li no, destined rau inverter lub cev muaj zog kev khiav hauj lwm tej yam kev mob yuav hnyav heev, thiab yog li ntawd rau lub cev muaj feem xyuam rau lub cev muaj zog kev ntsuas yuav tsum tau. tshwm sim.
Inverter lub cev muaj zog yog powered los ntawm lub inverter, cov zis los ntawm lub inverter yog non-sinusoidal rectangular waveform, lub siab harmonics generated los ntawm lub inverter muaj kev cuam tshuam ntau dua ntawm lub cev muaj zog kev ua tau zoo, lub siab harmonics yuav ua rau lub cev muaj zog stator tooj liab noj, rotor tooj liab noj, hlau noj thiab ntxiv poob, qhov tseem ceeb tshaj plaws yog lub rotor tooj liab noj. Vim qhov nce hauv kev poob, qhov tshwm sim ncaj qha tshaj plaws yog lub cev muaj zog kub nce.
Raws li cov laj thawj saum toj no, inverter lub cev muaj zog winding rwb thaiv tsev qauv piv nrog lub zaus lub cev muaj zog yuav muaj qee qhov sib txawv: inverter motor rwb thaiv tsev theem yuav tsum tsawg kawg yog ib theem siab dua li cov motors, xws li zaus motors feem ntau ntawm B theem rwb thaiv tsev, thiab inverter motors tsawg kawg yog raws li F qib rwb thaiv tsev tsim, ntxiv rau qhov sib txawv ntawm cov ntaub ntawv rwb thaiv tsev, electromagnetic kab sib txawv:
(1) Lub tshav kub-resistant qib ntawm electromagnetic hlau rau inverter motors yuav tsum tau txuam nrog lub rwb thaiv tsev qauv ntawm cov windings, thiab xaiv raws li cov qib tsis tsawg tshaj li 155.
(2) Electromagnetic hlau rau inverter motors yuav tsum tau xaiv raws li ib tug tshwj xeeb electromagnetic hlau, qhov sib txawv ntawm no hom ntawm electromagnetic hlau thiab zoo tib yam electromagnetic hlau nyob rau hauv lub tshwj xeeb ntawm insulating kua roj vanish, uas yuav zam tau qhov tshwm sim ntawm paug thiab teeb meem ntawm cua sov ntawm lub insulating nruab nrab, uas muaj peev xwm zoo lav kev nyab xeeb ntawm inverter motors thiab ntev kev pab cuam lub neej.
Hauv daim ntawv thov tiag tiag, qee cov tuam txhab tsim hluav taws xob hauv inverter lub cev muaj zog winding nrog cov kua roj vanish electromagnetic tuab, tuaj yeem txo qhov kev ua txhaum winding, tab sis tsis tuaj yeem daws qhov teeb meem. Yog li, los ntawm kev txheeb xyuas cov yam ntxwv tseem ceeb ntawm lub cev muaj zog inverter, kev siv tshwj xeeb inverter electromagnetic hlau, tuaj yeem daws qhov kub tsis kam thiab tiv thaiv qhov tshwm sim ntawm corona teeb meem.
