Indlela hlola multimeter transformer? imfundo

Ngokuvamile kudingeka uzijwayeze ngaphambili nge umbuzo kanjani ukuhlola transformer. Phela, uma ehluleka noma ukuntengantenga kuyoba nzima ukubheka imbangela yokwehluleka imishini. Lokhu iyithuluzi elingeyona inkimbinkimbi kagesi kungaba ukuhlonza multimeter ezivamile. Ake sibone indlela yokukwenza.

Uyini imishini?

Indlela hlola transformer, uma ungazi oyiyo? Cabangela isimiso isinyathelo futhi ezihlukahlukene imishini elula. On the kazibuthe core zethusi camera wire ohlobo kwesigaba esibekiwe ukuze iziphetho wahlala ukugeleza kanye yesibili emazombezombe.

ukudluliselwa Energy kuya yesibili emazombezombe wenziwa ngendlela yokuxhumana. Sekuvele kukhona cishe kuba sobala ukuthi ungahlola transformer. Ngokufanayo prozvanivat ezivamile inductance ohmmeter. I ohlobo akha ukumelana ukuthi lingalinganiswa. Nokho, le ndlela iyasebenza lapho ukubaluleka target waziwa. Ngempela, ukumelana ingahluka phezulu noma phansi ngenxa bafudumale. Lokhu kubizwa ngokuthi interturn short circuit.

idivayisi okunjalo ngeke ukukhipha inkomba voltage zamanje. Ohmmeter ngeke wesifunda evulekile kuphela noma efile iDemo. Ukuze ukusetshenziswa eyengeziwe zokuxilonga yi earthing ohmmeter efanayo. Indlela hlola Windings transformer ngaphandle kokwazi okutholakele?

Lokhu kunqunywa ukushuba we izintambo kokuphuma. Uma transformer is lehla, babashayeli esibulalayo lomthofu ngokuqinisekile uzoba mkhulu. Futhi ngokuvumelana, kunalokho: ku izintambo okokufaka isinyathelo-up mkhulu. Uma ezimbili emazombezombe okukhipha, ukushuba kungenzeka okufanayo, kufanele sikhumbule ngakho. Indlela engcono kakhulu ukubona amalebula futhi uthole Ukucaciswa imishini.

izinhlobo

Transformers zihlukaniswe amaqembu ezilandelayo:

• Ukwehlisa nokuvusa.
• Amandla ngokuvamile ukukhonza ukunciphisa supply voltage.
• Transformers samanje kokunikeza zamanje njalo umthengi kanye nokugcinwa yayo ngaphakathi kobubanzi kusengaphambili.
• Single- ne-multi-Isigaba.
• izinjongo zokushisela.
• Pulse.

Kuye injongo imishini esishintshile futhi isimiso indlela yombuzo kanjani ukuhlola transformer. Multimeter kungenzeka ukuthi ikhale kuphela idivayisi wosayizi omncane. imishini Power kakade zidinga indlela ehlukile ukuze inkinga.

embili indlela

indlela ohmmeter ukuxilongwa kuzonisiza umbuzo kanjani ukuqinisekisa transformer amandla. Ukumelana Prozvanivat phakathi kokuqala omunye emazombezombe. Ngakho, ubuqotho babantu isethi umqhubi. Ngaphambi ukuthi umzimba afeze ukuhlolwa oku ukungabi carbon imali, nokuwohloka ngenxa Ukushisa imishini.

Ngokulandelayo, ukukala ukubaluleka samanje ohms na eziqhathanisa passport. Uma labo azitholakali, idinga ukuhlola okungeziwe nginomdlandla. Prozvonit Kunconywa wonke amadivayisi okukhiphayo izindlu metal, ezixhunywe phansi.

Ngaphambi nesilinganiso, nqamula yonke imikhawulo transformer. Nqamula kusuka iketanga, futhi anconywe ukuphepha kwabo. Godu hlola ukutholakala i wesifunda electronic, okuyinto evame ekhona onobuhle yesimanje kwamandla. Kufanele futhi kube vypayat ngaphambi kokuhlola.

Ukumelana Infinite kubonisa lonke ukwahlukanisa. Amanani we kilohms ambalwa kakade asole mayelana ukuhlukaniswa izindlu. Kungase kube ngenxa zanqwabelana ukungcola, uthuli, noma umswakama esikhaleni emoyeni zedivayisi.

baphile

Ukuhlolwa abazenzi ngamandla lunikezwe uma kukhona umbuzo mayelana nendlela ukuhlola transformer interturn short circuit. Uma sazi ukubaluleka idivayisi supply voltage, okuyinto yakhelwe a transformer, le voltmeter ukukala ukubaluleka idling. Okungukuthi, izintambo phambili kukhona emoyeni.

Uma voltage lihlukile okuzisholo, kuphothulwe Han short circuit ku Windings. Uma ngesikhathi operation Crackle ezwakalayo arcing, a transformer enjalo kungcono ukuvala. Kuyinto okuyiphutha. Kukhona tolerances in the izilinganiso:

• Ukuze voltage amagugu angahluka 20%.
• Ukuze ukumelana izinga uku ububanzi bamanani 50% passport.

metering ammeter

Ake baqonde indlela ukuhlola transformer zamanje. Ifakiwe ezinhlwini uchungechunge esigcwele noma self-ezenziwe. Kubalulekile ukuthi ukubaluleka yamanje esingaphansi bokuzisholo. ammeter izilinganiso kwenziwe circuit eyinhloko kanye yesibili.

izinkomba yamanje iqhathaniswa lesibili kuya wesifunda eyinhloko. Okuningi ngokunembile, lo ihlukaniswe amagugu lokuqala ilinganiswa secondary emazombezombe. Isilinganiso ukuguqulwa kufanele kusekelwe encwadini kwebhukwana, futhi ukuqhathanisa nalabo etholwe izibalo. Imiphumela kufanele kube okufanayo.

Transformer zamanje singenakulinganiswa at lutho. Ohlangothini yesibili kuleli cala zingase zimiswe voltages eliphezulu kakhulu ukuthi kungalimaza ukwahlukanisa. Kufanele uqaphele le polarity, okuzokwenza ukusebenza lonke wiring.

Izinkinga ezivamile

Ngaphambi hlola microwave transformer, ukunikeza njalo iloli izinhlobo ukuthi benzelwe ngaphandle multimeter. Ngokuvamile Amadivayisi amandla behluleka ngenxa short circuit. It is esungulwe ukuhlolwa wesifunda amabhodi, nezixhumi, ukuxhumana. Ngaphansi umonakalo mechanical kwenzeka transformer izindlu kanye core.

bafake Mechanical zezakhi terminals transformer emshinini ezihambayo kwenzeka. ukuthengisela elikhulu izinkampani ezidinga Ukupholisa njalo. Uma engekho yayo, kungase overheat ancibilike ukwahlukanisa.

TDKS

Sibheka indlela ukuhlola ishayela yakho transformer. Kuvele ohmmeter kungenziwa esisungulwe kuphela ubuqotho Windings. Ukusebenza kahle zedivayisi Kumiswa ngokuxhuma wesifunda, lapho capacitor ehilelekile, umthwalo kanye generator umsindo.

Ngezinye ziqalise eyinhloko izinkampani isignali ishayela ku uhla kusuka 20 kuya ku-100 kHz. Ngesikhathi yesibili efanayo emazombezombe wenze izilinganiso ezidlula oscilloscope. Sungula khona ishayela ukuhlanekezela. Uma bengekho, wenze iziphetho mayelana idivayisi efanele.

Umumo gagasi ukuhlanekezela uthi Windings yasekelwa. Elungisa zinsizakuphila is hhayi Kunconywa ngokuzimela. Bakhandwa usethe egunjini lokucwaninga esibhedlela. Kunezinye izikimu uqinisekise ishayela Transformers, lapho zihlolwa ngokuba khona resonance coil. ukungabi Isimo sayo sibonisa ukungasebenzi zedivayisi.

Kungenzeka futhi ukuqhathanisa ukuma pulses yanikezwa eyinhloko izinkampani kanye yesibili sekukhona. Ukuphambuka ngefomu ekhuluma ukungasebenzi transformer.

Windings eziningana

Ukuze ukumelana yizilinganiso semikhawulweni mahhala ukuxhumana ngogesi. Khetha noma iyiphi esibulalayo futhi kukalwa isihlobo ukuba zonke ezinye ukumelana. Kunconywa ukuba alobe ukubaluleka kanye namathiphu uphawu-ihlolwe.

Ngakho singakwazi ukuthola uhlobo emazombezombe uxhumano: nalokho okutholwe Ngokwesilinganiso, ngaphandle kwabo, lo jikelele uxhumano iphuzu. Ngokuvamile ezinemigomo yokuphepha ehlukanisiwe Windings uxhumano. Isilinganiso kuzokwenziwa kuphela omunye izintambo.

Uma kukhona iphuzu ovamile, izilinganiso zobukhulu ukumelana phakathi kwawo wonke babashayeli. Amabili ukuphela phakathi emazombezombe kuyodingeka amagugu phakathi izintambo ezintathu kuphela. iziphetho eziningana itholakala transformers yakhelwe ukusebenza eziningana amanethiwekhi ihlelo 110 noma 220 volts.

ukuhlola umehluko wemisindo nemiqondo yamagama

Hum lapho transformer kungokwemvelo uma kule divayisi ethize. isusa kuphela futhi wokuqhuma ibonisa inkinga. Ngokuvamile, bafudumale ohlobo - lena operation evamile transformer. Ngokuvamile kwenzeka ukwehlisa amadivaysi.

Resonance kungadalwa lapho isixwayisi umzimba transformer. Khona-ke kufanele kube lula ukulungisa izinto nangokuvikela. Umsebenzi Windings kuyahlukahluka kakhulu nabantu oxhumana nabo alengayo some noma ezingcolile. izinkinga eziningi ixazululwe by bula metal kukhanye futhi zihambisana ne okutholakele ezintsha.

Lapho yokulinganisa voltage zamanje namanani kufanele acabangele ezingeni lokushisa elifanele, ubukhulu kanye nohlobo umthwalo. Control supply voltage Kuyadingeka. ukuvama isivivinyo liyadingeka. ubuchwepheshe Asian and American eyenzelwe 60 Hz, kuphumele eliphansi kakhulu okukhipha amagugu.

Ukulimaza uxhumano transformer kungadala ukungasebenzi zedivayisi. Kunoma ikuphi ayixhunyiwe ku-Windings we DC voltage. Ematfuba ngokushesha oplavyatsya ngenye indlela. Ukunemba izilinganiso kanye uxhumano abanekhono ngeke nje sithole imbangela ukwehluleka, kodwa kungase uyisuse ngendlela kobuhlungu.
