Vim li cas cov transformers yuav tsum tau qhwv nrog daim kab xev?

Hais los ntawm Lub Teeb ntawm Cov Khoom Siv

Kev qhwv daim kab xev yog ib qho txheej txheem uas siv ntau heev hauv kev tsim cov transformers. Yog li, cov haujlwm ntawm cov ntaub qhwv transformer yog dab tsi? Tsab xov xwm no xaus nrog kev qhia luv luv.

1. Ua raws li cov cai kev nyab xeeb. Peb paub tias cov cai kev nyab xeeb yog qhov tseem ceeb heev hauv cov transformers, vim lawv cuam tshuam ncaj qha rau kev nyab xeeb ntawm cov neeg siv kawg. Yog li ntawd, cov khoom raug cai xav tau kev nyab xeeb tshwj xeeb c

Raws li qhov yuav tsum tau ua, hauv AC-DC transformers, qhov tsawg kawg nkaus ntawm 6.4 hli yuav tsum tau ntsib ntawm cov transformers pib. Los ntawm kev qhwv daim kab xev ntawm cov theem thawj thiab theem ob ntawm lub transformer rau kev sib cais, nws tuaj yeem ua tiav.

2. Txhim kho kev ua haujlwm hluav taws xob. Daim kab xev tuaj yeem txhim kho lub peev xwm rwb thaiv hluav taws xob ntawm cov windings thiab cov txheej ntawm transformers, tiv thaiv kev tawg thaum lub sijhawm ua haujlwm transformer, thiab yog li cuam tshuam rau lub neej thiab kev ua haujlwm ruaj khov ntawm transformers.

Qee zaum, txhawm rau txhim kho qhov tsis kam ntawm lub zog hluav taws xob ntawm cov xov hlau, peb kuj nce tus naj npawb ntawm cov txheej ntawm daim kab xev. Qee lub transformers yuav siv 3 lossis txawm tias 4 txheej ntawm cov xov hlau pib es tsis txhob siv daim kab xev 2-txheej ib txwm muaj.

3. Tiv thaiv kev tso tawm corona. Cov transformers feem ntau tso tawm mus rau sab nraud thaum ua haujlwm ntawm qhov hluav taws xob siab, ua rau muaj kev cuam tshuam rau cov khoom ib puag ncig. Qhov muaj daim kab xev tuaj yeem tiv thaiv qhov kev nyiam no, yog li txo qhov kev cuam tshuam ntawm cov transformers rau ib puag ncig thiab txhim kho kev ua tau zoo EMI ntawm cov transformers.

4. Tiv thaiv kom cov xov hlau tsis txhob xoob. Thaum lub sijhawm ua haujlwm ntawm cov transformers, cov xov hlau yooj yim xoob los ntawm cov zog sab nraud. Kev siv daim kab xev tuaj yeem kho cov xov hlau tau zoo, uas yog qhov zoo rau kev ua haujlwm ruaj khov ntawm cov transformers.

Nws tsim nyog hais tias kev tiv thaiv kom tsis txhob muaj qhov xoob ntawm cov xov hlau tsis yog thaum lub sijhawm ua haujlwm ntawm lub tshuab hluav taws xob xwb. Hauv cov txheej txheem winding ntawm cov transformers, peb kuj yuav tsum siv daim kab xev los kho qhov winding ntawm qhov kawg. Txwv tsis pub, yog tias qhov winding xoob thaum dai cov taw, cov hlau pob yuav tsis sib npaug.

5. Pab txhawb kev sib txuas thiab kev sib txuas ntawm cov transformers. Thaum lub sijhawm ua haujlwm ntawm transformer winding, nws yooj yim pom tias tag nrho cov txheej tsis tau puv tag. Peb tuaj yeem daws qhov teeb meem no los ntawm kev kho cov txheej txheem winding, xws li uniform winding, sparse winding, thiab centered dense winding.

Txawm li cas los xij, kev kho qhov txoj kev winding tsuas yog tuaj yeem ua kom qhov tiaj tiaj ntawm qhov kev npaj ntawm qhov winding no (txheej), thiab tsis tuaj yeem lav qhov tiaj tiaj ntawm qhov winding tom ntej (txheej). Los ntawm kev qhwv daim kab xev, qhov teeb meem no tuaj yeem zam tau qee yam, yog li txhim kho qhov sib xws thiab kev ua haujlwm ntawm transformer.

6. Tiv thaiv cov qauv sab hauv ntawm lub transformer. Thaum lub sijhawm tsim khoom, kev thauj mus los, thiab kev teeb tsa ntawm cov transformers, lawv yuav raug cuam tshuam los ntawm ntau yam kev quab yuam sab nraud. Cov ntaub nplaum tuaj yeem muab qee qhov kev cuam tshuam buffering, yog li tiv thaiv sab hauv ntawm lub transformer.

7. Kho lawm. Tom qab kev sib dhos ntawm cov hlau nplaum transformer tiav lawm, lawv feem ntau raug kho nrog daim kab xev kom tiv thaiv kev hloov pauv tseem ceeb hauv inductance, uas tuaj yeem ua rau inductance tsis zoo.

Los ntawm kev siv daim kab xev, lub hlau nplaum thiab cov hlau pob kuj tuaj yeem kho tau zoo ua ke los tsim kom muaj cov qauv transformer tiav thiab ruaj khov, yog li ua kom ntseeg tau tias muaj kev ntseeg siab thiab sib xws ntawm lub transformer.

8. Cais thiab rwb thaiv tsev ntawm lwm yam khoom. Ntawm ntug ntawm ntau lub transformers, daim kab xev feem ntau siv, txawm tias daim kab xev ob txheej, los qhwv tag nrho lub transformer. Hauv qhov no, lub transformer tuaj yeem raug cais tawm ntawm lwm yam khoom hauv tag nrho lub tshuab siv daim kab xev kom ntseeg tau tias cov kev xav tau rwb thaiv tsev yooj yim ntawm cov khoom.

Txawm tias qee cov khoom siv fais fab muaj qhov siab txwv thiab tej zaum yuav qhwv sab saum toj ntawm lub transformer kom tsis txhob sib cuag ncaj qha ntawm lub plhaub fais fab thiab lub transformer, ua rau muaj teeb meem tiv taus hluav taws xob.

9. Tiv thaiv kom cov kua nplaum tsis txhob nkag mus rau hauv lub transformer. Cov kua nplaum uas nkag mus rau hauv lub transformer tuaj yeem ua rau muaj kev nthuav dav thiab kev sib txhuam ntawm cov cua sov, ua rau muaj kev hloov pauv ntawm inductance.

Hauv qee cov khoom siv fais fab uas muaj nplaum, txhawm rau tiv thaiv cov kua nplaum kom tsis txhob nkag mus rau sab hauv ntawm lub transformer, daim kab xev yog siv los qhwv tag nrho cov khoom ntawm lub transformer uas yooj yim rau cov kua nplaum kom ntseeg tau tias qhov ruaj khov ntawm qhov inductance.
