1. I-transformer iguqula njani amandla ombane?
I-transformer yenziwe ngokusekelwe kwi-electromagnetic induction. Iqukethe i-iron core eyenziwe ngamashiti ensimbi ye-silicon (okanye i-silicon sheet sheets) kunye neeseti ezimbini zeekhoyili ezilimale kwi-iron core. Ingundoqo yentsimbi kunye neekhoyili zifakwe kwi-insulated enye kwenye kwaye azikho uxhumano lombane.
Kuye kwaqinisekiswa ngokwethiyori ukuba umlinganiselo we-voltage phakathi kwekhoyili ephambili kunye ne-coil yesibini ye-transformer inxulumene nomlinganiselo wenani lokujika kwe-coil yokuqala kunye ne-coil yesibini, enokuthi ibonakaliswe ngolu hlobo lulandelayo: ikhoyili yokuqala. i-voltage / i-coil voltage yesibini = i-coil yokuqala iyajika / i-coil yesibini iyajika. Okukhona ukujika, kokukhona umbane uphezulu. Ngoko ke, kunokubonwa ukuba ukuba i-coil yesibini ingaphantsi kwe-coil yokuqala, i-transformer-down-down. Ngokuchasene noko, yi-transformer yokunyuka.
2. Bubuphi ubudlelwane obukhoyo phakathi kwekhoyili ephambili kunye nekhoyili yesibini ye-transformer?
Xa i-transformer isebenza kunye nomthwalo, utshintsho kwi-coil yangoku yesibini kuya kubangela utshintsho oluhambelanayo kwi-coil yangoku. Ngokomgaqo we-magnetic balance balance, i-conversely proportion to current of the primary and secondary coil. Ikhoyo ngoku kwicala elinokutshintsha okungaphezulu kuncinci, kwaye okwangoku kwicala elinokuguqulwa okuncinci kukhulu.
Inokubonakaliswa ngale fomyula ilandelayo: i-coil yokuqala yangoku / i-coil yesibini yangoku = i-coil yesibini iyajika / i-coil yokuqala iyajika.
3. Indlela yokuqinisekisa ukuba i-transformer ine-voltage ye-voltage elinganisiweyo?
I-voltage ephezulu kakhulu okanye ephantsi kakhulu iya kuchaphazela ukusebenza okuqhelekileyo kunye nobomi benkonzo ye-transformer, ngoko ke ukulawulwa kombane kuyimfuneko.
Indlela yokulawula i-voltage kukukhokela iimpompo ezininzi kwikhoyili ephambili kwaye uqhagamshele kumtshintshi wetephu. Umtshintshi wetephu utshintsha inani lokujika kwekhoyili ngokujikelezisa abafowunelwa. Ngethuba nje indawo yokutshintsha itephu iguqulwa, ixabiso elilinganisiweyo lombane elifunekayo linokufumaneka. Kufuneka kuqatshelwe ukuba ukulawulwa kwe-voltage kufuneka kwenziwe ngokuqhelekileyo emva kokuba umthwalo oxhunywe kwi-transformer unqunyulwe.
4. Ziziphi iilahleko ze-transformer ngexesha lokusebenza? Indlela yokunciphisa ilahleko?
Ilahleko ekusebenzeni kwe-transformer ibandakanya iinxalenye ezimbini:
(1) Ibangelwa ngumbindi wentsimbi. Xa ikhoyili inikwe amandla, imigca yamandla yamagnetic iyatshintshana, ibangela ukulahleka kwe-eddy current kunye ne-hysteresis kumbindi wentsimbi. Le lahleko ngokudibeneyo ibizwa ngokuba yi-iron loss.
(2) Kubangelwa ukuchasana kwekhoyili ngokwayo. Xa ikhoyo ngoku idlula kwiikhoyili eziphambili kunye nezesibini ze-transformer, ukulahlekelwa kwamandla kuya kuveliswa. Le lahleko ibizwa ngokuba yilahleko yobhedu.
Isixa sokulahleka kwentsimbi kunye nokulahleka kobhedu yilahleko ye-transformer. Ezi lahleko zinxulumene nomthamo wesiguquli, amandla ombane kunye nokusetyenziswa kwezixhobo. Ngoko ke, xa ukhetha i-transformer, amandla okusebenza kufuneka ahambelane nokusetyenziswa kwangempela kangangoko kunokwenzeka ukuphucula ukusetyenziswa kwezixhobo, kwaye kufuneka kuthathelwe ingqalelo ukuba ungasebenzi i-transformer phantsi komthwalo wokukhanya.
5. Yintoni ipleyiti yegama lesiguquli? Zeziphi ezona datha ziphambili zobugcisa kwi-nameplate?
I-nameplate ye-transformer ibonisa ukusebenza, ukucaciswa kobugcisa kunye neemeko zesicelo se-transformer ukuhlangabezana neemfuno zokukhetha komsebenzisi. Idatha ephambili yobugcisa ekufuneka ithathelwe ingqalelo ngexesha lokhetho zezi:
(1) I-kilovolt-ampere yomthamo olinganisiweyo. Oko kukuthi, umthamo wemveliso we-transformer phantsi kweemeko ezilinganisiweyo. Ngokomzekelo, umthamo olinganisiweyo we-transformer yesigaba esisodwa = Umgca we-U× I line; umthamo we-transformer yesigaba sesithathu = Umgca we-U× Ndingumgca.
(2) Umbane olinganisiweyo kwiivolthi. Bonisa i-terminal voltage ye-coil yokuqala kunye ne-terminal voltage ye-coil yesibini (xa ingaxhunywanga kumthwalo) ngokulandelanayo. Qaphela ukuba i-terminal voltage ye-transformer yesigaba sesithathu ibhekisela kwixabiso lomgca we-U.
(3) Umsinga olinganisiweyo kwii-amperes. Ibhekisela kumgca wexabiso le-line yangoku yokuba i-coil yokuqala kunye ne-coil yesibini ivumelekile ukuba idlule ixesha elide phantsi kweemeko zomthamo olinganisiweyo kunye nokunyuka kweqondo lokushisa elivumelekileyo.
(4) Umlinganiselo wombane. Ibhekisa kumlinganiselo wombane olinganisiweyo wekhoyili yokuqala ukuya kumbane olinganisiweyo wekhoyili yesibini.
(5) Indlela yocingo. I-transformer yesigaba esisodwa ineseti enye kuphela yeekhoyili zombane ophezulu kunye nophantsi kwaye isetyenziselwa kuphela ukusetyenziswa kwesigaba esisodwa. I-transformer enezigaba ezithathu ine-Y/△uhlobo. Ukongeza kule datha yobugcisa engentla, kukho kwakhona i-frequency elinganisiweyo, inani lezigaba, ukunyuka kweqondo lokushisa, ipesenti ye-impedance ye-transformer, njl.
6. Ziziphi iimvavanyo ekufuneka zenziwe kwi-transformer ngexesha lokusebenza?
Ukuqinisekisa ukusebenza okuqhelekileyo kwe-transformer, olu vavanyo lulandelayo kufuneka lwenziwe rhoqo:
(1) Uvavanyo lobushushu. Ubushushu bubaluleke kakhulu ukufumanisa ukuba i-transformer isebenza ngokuqhelekileyo. Imimiselo ichaza ukuba iqondo lokushisa eliphezulu leoli aliyi kudlula i-85C (oko kukuthi, ukunyuka kweqondo lokushisa ngu-55C). Ngokuqhelekileyo, ii-transformers zixhotyiswe ngezixhobo ezikhethekileyo zokulinganisa ubushushu.
(2) Umlinganiselo womthwalo. Ukuze kuphuculwe izinga lokusetyenziswa kwe-transformer kunye nokunciphisa ilahleko yamandla ombane, amandla okubonelela ngombane onokuthi athwale ngokwenene kufuneka alinganiswe ngexesha lokusebenza kwe-transformer. Umsebenzi wokulinganisa udla ngokuqhutywa ngexesha lencopho yokusetyenziswa kombane kwixesha ngalinye, kwaye ulinganiswa ngokuthe ngqo nge-clamp ammeter. Ixabiso langoku kufuneka libe yi-70-80% yexabiso langoku le-transformer. Ukuba idlula olu luhlu, kuthetha ukugqithiswa kwaye kufuneka kulungiswe ngokukhawuleza.
(3)Umlinganiselo wombane. Imimiselo ifuna ukuba uluhlu lokutshintsha kombane kufuneka lube ngaphakathi±I-5% yombane olinganisiweyo. Ukuba idlula olu luhlu, impompo kufuneka isetyenziswe ukulungisa i-voltage kuluhlu oluchaziweyo. Ngokuqhelekileyo, i-voltmeter isetyenziselwa ukulinganisa i-coil terminal voltage yesibini kunye ne-terminal voltage yomsebenzisi wokugqibela ngokulandelanayo.
