Momwe mungayesere transformer ndi multimeter
Zamkatimu
Kuyambira mayunitsi akuluakulu pamizere yamagetsi mpaka mayunitsi ang'onoang'ono pazida monga zojambulira mafoni, zosinthira zimabwera mumitundu yonse komanso kukula kwake.
Komabe, amagwira ntchito yofanana, kuwonetsetsa kuti zida zanu ndi zida zanu zaperekedwa kuchuluka kwa voteji ayenera kugwira ntchito moyenera.
Komabe, monga chipangizo china chilichonse chamagetsi, ma transfoma kukulitsa zophophonya.
Kuwasintha kungakhale njira yomwe simukufuna kugwiritsa ntchito, ndiye mumazindikira bwanji chosinthira ndikupeza yankho loyenera lomwe likufunika?
Nkhani iyi amapereka mayankho kwa izi, chifukwa timapereka chidziwitso cha momwe transformer imagwirira ntchito, komanso njira zosiyanasiyana zowunikira zolakwika.
Popanda kuchedwa, tiyeni tiyambe.
Transformer ndi chiyani
Transformer ndi chipangizo chomwe chimasintha chizindikiro cha alternating current (AC) kuchoka pa voteji kupita ku low voltage kapena mosemphanitsa.
Transformer yomwe imasandulika kukhala yotsika kwambiri kusiyana imatchedwa step down transformer ndipo ndi yofala kwambiri ya ziwiri zomwe zimatitumikira tsiku ndi tsiku.
Magetsi otsika pazingwe zamagetsi amatsitsa ma voliyumu masauzande kupita ku 240V otsika kuti agwiritse ntchito kunyumba.
Zida zathu zosiyanasiyana monga zolumikizira laputopu, ma charger amafoni ngakhalenso mabelu apakhomo amagwiritsa ntchito ma transformer awo.
Amachepetsa mphamvu yamagetsi mpaka 2V kuti chipangizocho chizigwira ntchito.
Njira ina ya izi imatchedwa step-up transformer ndipo imagwiritsidwa ntchito m'mafakitale apakati kuti awonjezere mphamvu yogawa.
Komabe, timakhala ndi chidwi kwambiri ndi ma transfoma otsika, chifukwa izi ndi zomwe timakonda kuchita nazo. Koma zimagwira ntchito bwanji?
Momwe Step Down Transformers Amagwirira Ntchito
Ma thiransifoma otsika amagwiritsa ntchito ma koyilo awiri, omwe amadziwikanso kuti ma windings. Izi ndi coil yoyamba ndi yachiwiri.
Koyilo yoyambira ndi koyilo yolowera yomwe imalandira pano kuchokera ku gwero lamagetsi la AC monga chingwe chamagetsi.
Koyilo yachiwiri ndi koyilo yotulutsa yomwe imatumiza siginecha yotsika ku zida zapanyumba panu.
Koyilo iliyonse imadulidwa pachimake ndipo ikadutsa pa coil yoyamba, mphamvu ya maginito imapangidwa yomwe imapangitsa kuti pakhale koyilo yachiwiri.
Mu ma transfoma otsika, mapindikidwe oyambira amakhala ndi makhoti ambiri kuposa mapindikidwe achiwiri. Popanda kulowa mwatsatanetsatane, kuchuluka kwa ma windings kumayenderana mwachindunji ndi mphamvu yamagetsi yamagetsi (EMF) yopangidwa ndi koyilo.
Kuchokera ~ V
Tiyeni tiyitane kulowera kolowera kwa koyilo W1, kutulutsa kwa koyilo W2, mphamvu yolowera E1 ndi voteji E2. Ma transfoma otsika amakhala ndi matembenuzidwe ambiri pa koyilo yolowera kuposa koyilo yotulutsa.
P1> P2
Izi zikutanthauza kuti voteji ya koyilo (yachiwiri) ndiyotsika kuposa mphamvu ya koyilo yolowera.
E2 <E1
Chifukwa chake voteji yayikulu ya AC imasinthidwa kukhala yotsika. Kuonjezera apo, mphamvu yapamwamba imadutsa mu coil yachiwiri kuti igwirizane ndi mphamvu ya ma windings onse awiri.
Transformers sizinthu zonse, koma ndi chidziwitso chofunikira chomwe mungafune musanayese transformer yanu.
Ngati mukuganiza kuti thiransifoma yanu siyikuyenda bwino, mumangofunika multimeter kuti muzindikire.
Momwe mungayesere transformer ndi multimeter
Kuti muyese thiransifoma, mumagwiritsa ntchito multimeter kuyesa kuwerengera kwamagetsi a AC pamalo olowera ndi ma terminals pomwe cholumikizira chikulumikizidwa. Mumagwiritsanso ntchito ma multimeter kuti muyese kupitiliza kwa thiransifoma ngati sichikulumikizidwa ndi gwero lililonse lamagetsi. .
Adzafotokozedwa motsatira.
Mayeso olowetsa ndi kutulutsa
Nthawi zambiri, mayesowa amangochitika pamagawo otulutsa a transformer.
Komabe, kuti muwonetsetse kuwerengedwa kolondola kuchokera ku ma terminals otulutsa, muyenera kutsimikiza kuti ma voliyumu omwe amagwiritsidwa ntchito pawo ndiwolondola. Ndicho chifukwa chake mukuyesa gwero lanu.
Kwa zida zapakhomo, magwero azizindikiro zolowera nthawi zambiri amakhala m'makoma. Mukufuna kuwonetsetsa kuti akupereka kuchuluka kwamagetsi.
Kuti muchite izi, tsatirani izi
- Khazikitsani multimeter kukhala 200 VAC.
- Ikani ma multimeter otsogolera pazitsulo zamagetsi. Kwa makhoma, mumangolowetsa mawaya mumabowo otulutsira.
Mukuyembekeza kuwona mtengo pakati pa 120V ndi 240V, koma zimatengera.
Ngati zowerengera sizili zolondola, magetsi anu angayambitse mavuto. Ngati zowerengerazo zili zolondola, pitilizani kuyang'ana ma terminals a transformer. Chitani,
- Lumikizani thiransifoma ku magetsi
- Chepetsani kuchuluka kwa ma voltage pa multimeter
- Ikani ma multimeter otsogolera pazotulutsa za transformer yanu.
- Onani zowerengera
Poyang'ana zowerengera pa multimeter, mumayang'ana ngati zotsatira zake ndi zolondola. Apa mukuyang'ana mawonekedwe omwe akulimbikitsidwa a transformer kuti mutsirize.
Transformer cheke kukhulupirika
Kuyesa kopitilira kwa Transformer kumachitika kuti zitsimikizire kuti palibe njira yotseguka kapena yayifupi pamakoyilo. Mumayesa izi pamene thiransifoma yachotsedwa pamagetsi. Mukutani?
- Khazikitsani sikelo ya multimeter kukhala Ohm kapena Resistance. Izi nthawi zambiri zimatanthauzidwa ndi chizindikiro (Ω).
- Ikani zotsogola za multimeter pagawo lililonse lolowera pa thiransifoma yanu.
Kumene thiransifoma ili ndi dera lalifupi, multimeter idzapereka mawerengedwe apamwamba kwambiri kapena opanda malire. Kuwerenga kopanda malire kumaimiridwa ndi "OL" yomwe imayimira "Open Loop".
Ngati malo olowetsamo akuwoneka ngati abwinobwino, mumabwereza izi pazotulutsa.
Zikachitika kuti imodzi mwa ma terminals awa imapereka mtengo wapamwamba kapena wopanda malire, chosinthiracho chiyenera kusinthidwa. Nayi kanema wowonetsa njirayi.
Pomaliza
Kuwunika kwa Transformer ndi njira yomwe imayenera kusamaliridwa mosamala, makamaka poyang'ana zolowera ndi zotuluka.
Komabe, muyenera kuzindikira kuti ma transformer nthawi zambiri amakhala ndi moyo wautali. Vuto ndi iwo limasonyeza kusagwira ntchito kwinakwake mumayendedwe amagetsi.
Pachifukwa ichi, tikulimbikitsidwa kuti tiyang'ane ma transformer omwe angoikidwa kumene kuti amveke zoipa, komanso kuti muwonetsetse kuti mbali zina za dera, monga fuse, zili bwino.
Mafunso ofunsidwa kawirikawiri
Kodi mungadziwe bwanji ngati thiransifoma ndiyolakwika?
Ngati thiransifomayo ili yolakwika, mutha kuwona kuti chipangizocho sichigwira ntchito, woyendetsa dera amazimitsa nthawi zonse, kapena mumamva phokoso la transformer. Mamita akuthandizaninso kuti mufufuzenso ma coils ndi kuwerengera kwawo kwamagetsi.
Muchita chiyani kuti muyese kupitiliza kwa transformer?
Kuti muwone kukhulupirika kwa thiransifoma, chotsani ndikuyika ma probe a mita pamagawo olowera. Ngati ma terminal atulutsa mtengo wapamwamba kapena wopanda malire "OL", ndiye kuti palibe kupitiliza. Chimodzimodzinso ndi ma terminals otulutsa.
Chimachitika ndi chiyani thiransifoma ikalephera?
Transformer ikalephera, chipangizocho sichingagwire ntchito, kapena mutha kumva kung'ung'udza kapena kung'ung'udza kochokera ku transformer.
Kodi kukana kwa transformer ndi chiyani?
Kukaniza kwa transformer kumadalira chipangizo chomwe chimapangidwira mphamvu. Muyenera kuyang'ana mawonekedwe a transformer kuti mutsirize.
