Indlela Yokuhlola I-Transformer Nge-Multimeter (Izinyathelo Ezi-4)

Ama-Transformer ayizingxenye zikagesi ezibalulekile ezidlulisa amandla phakathi kwamasekhethi amabili noma ngaphezulu. Kodwa-ke, ngezinye izikhathi bangahluleka futhi babangele ukwehluleka kwesifunda. Ngakho-ke, kubaluleke kakhulu ukuhlola i-transformer ukuze amadivaysi akho asebenze ngaphandle kwengozi yomlilo noma izenzakalo eziyingozi.

Kunezindlela ezahlukahlukene zokuhlola ama-transformer, futhi ephumelela kakhulu i-multimeter yedijithali. Ngakho-ke, funda futhi uthole ukuthi ungayihlola kanjani i-transformer nge-multimeter! Lo mhlahlandlela uzokuthatha isinyathelo ngesinyathelo!

Ukuhlonza Izinkinga Ze-Transformer

Kunezindlela eziningana zokunquma ukuthi i-transformer yakho imbi, futhi i-multimeter yedijithali ingenye yazo. I-DMM iyithuluzi elisebenza kahle kakhulu lokubona amaphutha e-transformer, ngaphandle komsebenzi wayo oyisisekelo wokuhlola i-voltage, yamanje, njll. Uma konke kuhamba kahle, kufanele ukwazi ukuthola noma imaphi amaphutha e-transformer futhi ufunde ukuthi ungawalungisa kanjani. ingasebenza ngokujwayelekile futhi.

Ngakho-ke, ngaphambi kokuba uqale ukuhlola i-transformer nge-multimeter, kungaba ngcono ukukhomba ulwazi olubalulekile mayelana nama-transformer. Ngakho-ke, kufanele:

Hlola i-transformer ngeso lengqondo

Isizathu esijwayelekile sokuhluleka kwe-transformer ukushisa ngokweqile, okushisa ucingo lwangaphakathi lwe-transformer emazingeni okushisa aphezulu. Ngenxa yalokho, i-transformer noma indawo ezungezile ngokuvamile ikhubazekile ngokomzimba. Ungayihloli i-transformer uma ivuvukele ngaphandle noma ishile, kodwa yishintshe esikhundleni.

Thola izintambo ze-transformer

I-wiring kufanele imakwe ngokucacile ku-transformer. Kodwa-ke, indlela elula yokuthola ukuthi i-transformer ixhunywe kanjani ukuthola umdwebo wesifunda. Ungathola umdwebo wesekethe kulwazi lomkhiqizo noma kuwebhusayithi yomkhiqizi wesekethe. (1)

Yazi izinhlangothi ze-transformer

I-transformer engu-24V inohlangothi oluyinhloko (i-voltage ephezulu) kanye nohlangothi lwesibili (i-voltage ephansi).

• Uhlangothi oluyinhloko (amandla kagesi aphezulu) luyi-voltage yomugqa we-transformer kanye nokuxhumeka kukagesi ku-voltage yokuhlinzeka, ngokuvamile engu-120 VAC.
• Uhlangothi lwesibili (i-voltage ephansi) amandla aguqulelwe ku-24 volts.

Ku-transformer esetshenziselwa uhlelo lwe-24V, alukho uxhumano lukagesi oluqondile phakathi kwezingxenye eziseceleni eziphakeme neziphansi.

Indlela Yokuhlola I-Transformer Nge-Multimeter (Izinyathelo)

Kulo mhlahlandlela, sizobe sihlola i-24V transformer futhi uzodinga okulandelayo:

• Iscrewdriver
• i-multimeter

Ngakho-ke, ungabheka kanjani i-transformer yamandla nge-multimeter? Yenza lokhu okulandelayo:

Isinyathelo 1: Susa amakhava kagesi 

Vala amandla esekethe. Susa zonke izembozo zikagesi ezimboze i-transformer nge-screwdriver. Ngincoma ukuthi uhlole imiyalelo yomkhiqizi ukuze uqinisekise ukufinyelela kwe-transformer.

Isinyathelo sesi-2: Faka izintambo ku-multimeter

Shintsha isilungiselelo se-multimeter sibe "Ohm", bese ufaka umkhondo wokuhlola obomvu nomnyama ku-multimeter. I-probe emnyama ingena emgodini ojwayelekile, futhi i-probe ebomvu ingena ku-Ohm socket. Ngemuva kwalokho, xhuma iziphetho zezintambo ezimbili ndawonye. Kufanele ibonise ama-ohms aziro noma isifunda esivaliwe.

Isinyathelo sesi-3: Xhuma Ukuholela Ehlangothini Oluyinhloko 

Xhuma i-multimeter iholela ohlangothini oluphezulu noma umkhondo oyinhloko we-transformer. Imitha kufanele ikhombe ukufundwa kokumelana, futhi uhlobo lwe-transformer olusetshenziswa kumjikelezo luzothinta lokhu kufundwa. Uma imitha ibonisa isifunda esivulekile noma ukumelana okungapheli, udinga ukufaka esikhundleni se-high side transformer.

Isinyathelo sesi-4: Yenza okufanayo ngohlangothi lwesibili 

Landela inqubo efanayo esinyathelweni sesi-3 ngokuxhunywa ohlangothini lwe-voltage ephansi noma kusekethe yesibili. Imitha kufanele ibike isilinganiso esinembile sokumelana ngama-ohms ohlangothini olungezansi. Khona-ke, uma i-multimeter ibonisa ukufundwa okungenamkhawulo noma okuvulekile okubanzi, uhlangothi lwe-voltage ephansi lonakaliswa ngaphakathi futhi i-transformer idinga ukushintshwa.

 Amathiphu Ayisisekelo

• Umsindo obhiziyo noma oklewulayo yisixwayiso esivamile sokuthi i-transformer isizosha.
• Uma uthinta ama-probe futhi uhlangothi olulodwa kuphela lwe-transformer lungasebenzi, ungase uzwe umsindo ozwakalayo. Kulokhu akukho okwamanje okugeleza nge-transformer futhi izama ukusebenza ngokumelene nayo.
• Ungacabangi ukuthi izinhlangothi eziyinhloko nezesibili ze-transformer zixhunywe emhlabathini ofanayo kagesi. Ngokuvamile kubhekiselwa kuzo ngezizathu ezahlukene. Ngakho-ke, qaphela ukubeka phansi okuhlukene lapho wenza izilinganiso.
• Ungahlola futhi ubuqotho be-transformer. Ukuhlola ukuqhubeka kwe-transformer kubalulekile ukubona ukuthi ikhona yini indlela yokuthi ugesi udlule phakathi kwamaphuzu amabili okuxhumana. Uma ingekho indlela yamanje, kukhona okungahambanga kahle ngaphakathi kwe-transformer yakho futhi idinga ukulungiswa.

Okumele kuqashelwe

Ukuze uhlole ngokuphepha i-transformer, lokhu okulandelayo kufanele kucatshangelwe:

• Nqamula wonke amandla kumshini noma kudivayisi ngaphambi kokwenza noma yiziphi izivivinyo. Ungalokothi uhlole idivayisi exhunywe kumthombo wamandla wangaphandle.
• Hlala uhlola endaweni ephephile neyomile kude nezingane nezilwane ezifuywayo.
• Ukuthintana ngengozi namandla esekethe kuyilapho amasekhethi evuliwe futhi enikezwe amandla okuhlolwa kungase kubangele ukushaqeka kukagesi noma umonakalo. Sebenzisa kuphela umkhondo we-DMM ukuze uthinte isekethe.
• Ukusebenza ngogesi kuyingozi kakhulu. Ngakho-ke, qaphela lapho wenza kanjalo. Ungavuli i-transformer enezintambo eziphukile noma umonakalo obonakalayo, ngoba lokhu kungaholela ekushayweni kukagesi.
• Hlola i-transformer kuphela uma ujwayelene nezinto zikagesi futhi usebenzise i-multimeter ukuhlola i-voltage, yamanje, kanye nokumelana nenani elibanzi lamanani.

Transformer: isebenza kanjani? (Ibhonasi)

I-transformer iyisisetshenziswa sikagesi esibalulekile esishintsha i-voltage yesiginali ye-alternating current (AC). Lokhu kufezwa ngokuguqula ugesi we-AC ube amasignali kagesi aphezulu noma aphansi. Lokhu kubalulekile ngoba kuqinisekisa ukudluliswa kukagesi okuphephile ebangeni elide. Kungenjalo, ungasebenzisa i-transformer ukunyusa noma ukwehlisa i-voltage yesiginali ye-AC ngaphambi kokuthi ingene esakhiweni.

Ama-Transformer afika ngobukhulu obuhlukahlukene kanye nokucushwa, kodwa wonke asebenza ngokwakha indawo kazibuthe ezungeze amakhoyili amabili ocingo, aziwa ngokuthi ama-winding. Ukusonga okukodwa kuxhumeke ngqo kumthombo we-AC, njengolayini wamandla. Ngakolunye uhlangothi, enye i-winding ixhunywe kumthwalo kagesi, njengesibani. Lapho i-current idlula ikhoyili eyodwa, idala inkambu kazibuthe ezungeza womabili amakhoyili. Uma zingekho izikhala phakathi kwala mawindi amabili, azohlala ene-polarity ephambene, enye ibheke enyakatho enye ibheke eningizimu. Ngakho-ke i-transformer ikhiqiza i-alternating current.

Primary kanye Sekondari

Amakhoyili okuqala nawesibili e-transformer amakhoyili ezintambo akhiqiza amandla ashintshayo. Ikhoyili eyinhloko ixhunywe kuntambo kagesi kanti ikhoyili yesibili ixhunywe kumthwalo kagesi. Ungashintsha i-voltage ephumayo ye-transformer ngokushintsha inani lamanje ngokujika ngakunye. (2)
