Momwe Mungayesere Transformer ndi Multimeter (Masitepe 4)

Ma Transformers ndi zinthu zofunika kwambiri zamagetsi zomwe zimasamutsa mphamvu pakati pa mabwalo awiri kapena kupitilira apo. Komabe, nthawi zina amatha kulephera ndikuyambitsa kulephera kwa dera. Chifukwa chake, ndikofunikira kuyesa chosinthira kuti zida zanu zizigwira ntchito popanda chiwopsezo chamoto kapena zoopsa zilizonse.

Pali njira zosiyanasiyana zoyesera zosinthira, ndipo zogwira mtima kwambiri ndi multimeter ya digito. Chifukwa chake, werengani ndikupeza momwe mungayesere chosinthira ndi multimeter! Bukuli lidzakutengerani pang'onopang'ono!

Kuzindikira Mavuto a Transformer

Pali njira zingapo zodziwira ngati thiransifoma yanu ndi yoyipa, ndipo multimeter ya digito ndi imodzi mwazo. A DMM ndi chida chothandiza kwambiri chodziwira zolakwika za transformer, kupatula ntchito yake yayikulu yoyang'ana magetsi, zamakono, ndi zina zotero. Ngati zonse zikuyenda bwino, muyenera kupeza zolakwika za transformer ndikuphunzira momwe mungakonzere. imatha kugwiranso ntchito bwino.

Choncho, musanayambe kuyesa thiransifoma ndi multimeter, zingakhale bwino kuti mudziwe zambiri zokhudza osintha. Chifukwa chake, muyenera:

Yang'anani mowoneka bwino thiransifoma

Zomwe zimayambitsa kulephera kwa thiransifoma ndikutentha kwambiri, komwe kumatenthetsa waya wamkati wa thiransifoma kutentha kwambiri. Zotsatira zake, thiransifoma kapena malo ozungulira nthawi zambiri amakhala opunduka mwakuthupi. Osayang'ana thiransifoma ngati yatupa kapena yapsa kunja, koma m'malo mwake.

Dziwani mawaya a transformer

Mawaya ayenera kulembedwa bwino pa transformer. Komabe, njira yosavuta yodziwira momwe thiransifoma imalumikizirana ndikupeza chithunzi chozungulira. Mutha kupeza chithunzi chozungulira pazogulitsa kapena patsamba la wopanga dera. (1)

Dziwani mbali za transformer

Transformer ya 24V ili ndi mbali yoyamba (yamphamvu kwambiri) ndi yachiwiri (yotsika kwambiri).

• Mbali yoyamba (yokwera kwambiri) ndi mphamvu yamagetsi ya thiransifoma ndi kulumikizidwa kwamagetsi kumagetsi operekera, nthawi zambiri 120 VAC.
• Mbali yachiwiri (yotsika) ndi mphamvu yosinthidwa kukhala 24 volts.

Mu thiransifoma yogwiritsidwa ntchito pa 24V, palibe kulumikizana kwachindunji kwamagetsi pakati pa magawo apamwamba ndi otsika.

Momwe Mungayesere Transformer ndi Multimeter (Masitepe)

Mu bukhuli, tikhala tikuyesa chosinthira cha 24V ndipo mudzafunika izi:

• Screwdriver
• multimeter

Ndiye, momwe mungayang'anire chosinthira mphamvu ndi multimeter? Chitani izi:

Gawo 1: Chotsani zophimba zamagetsi 

Zimitsani mphamvu yamagetsi. Chotsani zophimba zonse zamagetsi zomwe zimaphimba thiransifoma ndi screwdriver. Ndikupangira kuyang'ana malangizo a wopanga kuti mutsimikizire kupeza kwa transformer.

Khwerero 2: Ikani mawaya mu multimeter

Sinthani makonda a multimeter kukhala "Ohm", kenaka ikani zoyeserera zofiira ndi zakuda mu multimeter. Kufufuza kwakuda kumapita mu dzenje lokhazikika, ndipo kafukufuku wofiira amapita muzitsulo za Ohm. Pambuyo pake, gwirizanitsani malekezero a mawaya awiri pamodzi. Iyenera kuwonetsa zero ohms kapena dera lotsekedwa.

Khwerero 3: Lumikizani Zotsogolera ku Mbali Yaikulu 

Lumikizani ma multimeter amatsogolera kumtunda wapamwamba kapena kutsogola koyambirira kwa thiransifoma. Mamita ayenera kuzindikira kutsutsa kuwerengera, ndipo mtundu wa transformer womwe umagwiritsidwa ntchito pozungulira udzakhudza kuwerenga uku. Ngati mita ikuwonetsa dera lotseguka kapena kukana kopanda malire, muyenera kusintha mawonekedwe amtundu wapamwamba.

Khwerero 4: Chitani zomwezo ndi mbali yachiwiri 

Tsatirani njira yomweyo mu gawo 3 polumikizira mbali yamagetsi otsika kapena mugawo lachiwiri. Meta iyenera kufotokoza muyeso wolondola wa kukana mu ma ohm kumbali ya pansi. Kenako, ngati ma multimeter akuwonetsa kuwerenga kopanda malire kapena kotseguka, mbali yotsika yamagetsi imawonongeka mkati ndipo chosinthira chiyenera kusinthidwa.

 Malangizo Oyambira

• Phokoso la phokoso kapena phokoso ndi chenjezo lodziwika kuti transformer yatsala pang'ono kuyaka.
• Mukakhudza ma probes ndipo mbali imodzi yokha ya transformer sikugwira ntchito, mukhoza kumva phokoso la phokoso. Pachifukwa ichi palibe pompopompo ikuyenda kudzera mu thiransifoma ndipo imayesa kudziletsa yokha.
• Musaganize kuti mbali zoyambirira ndi zachiwiri za transformer zimagwirizanitsidwa ndi nthaka yomweyo yamagetsi. Nthawi zambiri amatchulidwa pazifukwa zosiyanasiyana. Choncho, samalani ndi malo osiyana popanga miyeso.
• Mukhozanso kuyang'ana kukhulupirika kwa transformer. Kuwona kupitiriza kwa transformer ndikofunikira kuti muwone ngati pali njira yoti magetsi adutse pakati pazigawo ziwiri zolumikizana. Ngati palibe njira yamakono, chinachake chalakwika mkati mwa transformer yanu ndipo chiyenera kukonzedwa.

Kusamala

Kuti muyese bwino transformer, zotsatirazi ziyenera kuganiziridwa:

• Chotsani mphamvu zonse ku chipangizo kapena chipangizo musanayese mayeso aliwonse. Osayesa chipangizo cholumikizidwa ndi gwero lamagetsi lakunja.
• Yesani nthawi zonse pamalo otetezeka, owuma kutali ndi ana ndi ziweto.
• Kulumikizana mwangozi ndi magetsi ozungulira pomwe mabwalo ali otseguka komanso opatsidwa mphamvu zoyesa kungayambitse kugwedezeka kwamagetsi kapena kuwonongeka. Gwiritsani ntchito DMM yokha yomwe imatsogolera kukhudza dera.
• Kugwira ntchito ndi magetsi ndikoopsa kwambiri. Choncho, samalani pochita zimenezi. Osayatsa thiransifoma yokhala ndi mawaya ophwanyika kapena kuwonongeka kowoneka, chifukwa izi zitha kuyambitsa kugwedezeka kwamagetsi.
• Yesani thiransifoma yokhayo ngati mumadziwa zida zamagetsi ndipo mwagwiritsa ntchito ma multimeter kuyesa mphamvu yamagetsi, yapano, komanso kukana pamitundu yambiri.

Transformer: imagwira ntchito bwanji? (Bonasi)

Transformer ndi chipangizo chofunikira chamagetsi chomwe chimasintha voteji ya siginecha ya alternating current (AC). Izi zimatheka potembenuza magetsi a AC kukhala ma siginecha apamwamba kapena otsika. Izi ndizofunikira chifukwa zimaonetsetsa kuti magetsi akuyenda bwino pamtunda wautali. Kapenanso, mutha kugwiritsa ntchito thiransifoma kuti mukweze kapena kutsitsa voteji ya siginecha ya AC isanalowe mnyumbamo.

Ma Transformers amabwera mosiyanasiyana komanso mosiyanasiyana, koma onse amagwira ntchito popanga mphamvu ya maginito kuzungulira ma waya awiri, omwe amadziwika kuti ma windings. Mphepo imodzi imalumikizidwa mwachindunji ku gwero la AC, ngati chingwe chamagetsi. Kumbali ina, mapiritsi ena amalumikizidwa ndi katundu wamagetsi, monga babu. Mphamvu ikadutsa pa koyilo imodzi, imapanga mphamvu ya maginito yomwe imazungulira makola onse awiri. Ngati palibe mipata pakati pa mapiringiro awiriwa, nthawi zonse amakhala ndi polarity yosiyana, imodzi yolozera kumpoto ndi ina yolozera kumwera. Chifukwa chake, transformer imapanga ma alternate current.

Pulayimale ndi Sekondale

Ma koyilo oyambira ndi achiwiri a thiransifoma ndi ma waya omwe amapanga magetsi osinthasintha. Koyilo yoyamba imalumikizidwa ndi chingwe chamagetsi ndipo koyilo yachiwiri imalumikizidwa ndi katundu wamagetsi. Mutha kusintha mphamvu yamagetsi ya transformer posintha kuchuluka kwaposachedwa pamapiritsi aliwonse. (2)

Maupangiri ena ophunzirira ma multimeter pansipa omwe mutha kuwonanso.

• Momwe mungayang'anire voteji ya 240 V ndi multimeter?
• Momwe mungawerenge ohms pa multimeter
• Momwe mungayesere koyilo ndi multimeter
