Indlela yokuhlola i-transformer nge-multimeter

Kusukela kumayunithi amakhulu kolayini bamandla kuya kumayunithi amancane kumadivayisi afana namashaja efoni, ama-transformer afika ngazo zonke izinhlobo nosayizi.

Nokho, zenza umsebenzi ofanayo, ziqinisekisa ukuthi izisetshenziswa zakho nezinto zikagesi zihlinzekwa inani eliqondile le-voltage kufanele basebenze ngendlela efanele.

Nokho, njenganoma iyiphi enye idivayisi kagesi, transformer ukuthuthukisa ukushiyeka.

Ukuwashintsha kungase kube inketho ongafuni ukuyisebenzisa, ngakho-ke usihlonza kanjani isiguquli bese unquma isisombululo esifanele esisidingayo?

Lesi sihloko inikeza izimpendulo zalokhu, ngoba sinikeza ulwazi mayelana nendlela i-transformer esebenza ngayo, kanye nezindlela ezihlukahlukene zokuyibheka amaphutha.

Ngaphandle kokuchitha isikhathi, ake siqale.

Iyini i-transformer

I-transformer iyithuluzi eliguqula isignali yamanje (AC) esuka ku-voltage ephezulu iye ku-voltage ephansi noma ngokuphambene nalokho. 

I-transformer eguqulela kumehluko ongaba namandla aphansi ibizwa ngokuthi i-step down transformer futhi ivame kakhulu kokubili okusisebenzela nsuku zonke.

Iziguquli ezehlayo ezintanjeni zikagesi zehlisa izinkulungwane zamandla kagesi ziye ku-voltage ophansi ongu-240V ukuze zisetshenziswe ekhaya.

Imishini yethu ehlukahlukene njengezixhumi eziphathwayo eziphathwayo, amashaja ezingcingo ngisho nezinsimbi zasemnyango zisebenzisa ama-transformer azo.

Banciphisa i-voltage ibe ngu-2V kuphela ukugcina idivayisi isebenza.

Enye indlela yalezi ibizwa ngokuthi i-step-up transformer futhi ivamise ukusetshenziswa ezimbonini zamandla ezimaphakathi ukwandisa amandla okusabalalisa.

Kodwa-ke, sinesithakazelo esikhulu kuma-transformer asuka phansi, ngoba yilokhu esivame ukubhekana nakho. Kodwa zisebenza kanjani?

Indlela I-Step Down Transformers Esebenza Ngayo

Iziguquli eziya phansi zisebenzisa amakhoyili amabili, aziwa nangokuthi ama-winding. Lezi yikhoyili yokuqala kanye nekhoyili yesibili. 

Ikhoyili eyinhloko ikhoyili efakayo ethola amandla asuka kumthombo kagesi we-AC njengentambo kagesi.

Ikhoyili yesibili yikhoyili ephumayo ethumela amasignali amancane ezinto zikagesi ezisendlini yakho.

Ikhoyili ngayinye ilinyazwa kumongo futhi lapho i-current idlula kukhoyili eyinhloko, kwakhiwa inkambu kazibuthe edonsa amandla akhona kukhoyili yesibili.

Ku-transformer eyehlayo, ukujikajika okuyinhloko kunamajika amaningi kunamajika esibili. Ngaphandle kokungena emininingwaneni, inani lama-winding lilingana ngokuqondile ne-voltage yamandla kazibuthe kagesi (EMF) ekhiqizwa ikhoyili.

Kusuka ~ V

Ake sibize i-input winding yekhoyili ethi W1, ukuphuma kwekhoyili ethi W2, i-voltage yokufaka engu-E1 kanye ne-voltage ephumayo E2. Ama-transformer asuka phansi anamajika amaningi kukhoyili yokufaka kunaleyo ephumayo.

P1 > P2

Lokhu kusho ukuthi i-voltage yekhoyili ephumayo (yesibili) iphansi kune-voltage yekhoyili yokufaka.

E2 <E1

Ngakho-ke i-voltage ye-AC ephezulu iguqulwa ibe phansi. Ukwengeza, i-current ephakeme idlula ikhoyili yesibili ukulinganisa amandla omabili ama-winding. 

Ama-Transformer awazona zonke izinto, kodwa wulwazi oluyisisekelo ozoludinga ngaphambi kokuhlola i-transformer yakho. 

Uma usola ukuthi i-transformer yakho ayisebenzi kahle, udinga nje i-multimeter ukuyixilonga.

Indlela yokuhlola i-transformer nge-multimeter

Ukuze uhlole i-transformer, usebenzisa i-multimeter ukuhlola ukufundwa kwamandla kagesi e-AC kumthombo wokufakwayo namatheminali okukhiphayo kuyilapho i-transformer ixhunyiwe. Uphinde usebenzise i-multimeter ukuhlola ukuqhubeka kwe-transformer uma ingaxhumekile kunoma yimuphi umthombo wamandla. .

Zizochazwa ngokulandelayo.

Ukuhlola okokufaka nokuphumayo

Ngokuvamile, lokhu kuhlolwa kwenziwa kuphela kumatheminali okukhiphayo we-transformer.

Kodwa-ke, ukuze uqinisekise ukufundwa okunembile okuvela kumatheminali okukhiphayo, kufanele uqiniseke ukuthi i-voltage esetshenziswa kuzo nayo inembile. Yingakho uhlola umthombo wakho wokufaka.

Ngezinto zikagesi zasendlini, imithombo yesignali yokufaka imvamisa iyizisekelo ezindongeni. Ufuna ukuhlola ukuthi banikeza inani eliqondile le-voltage.

Ukuze wenze lokhu, landela lezi zinyathelo

• Setha i-multimeter ibe ngu-200 VAC.
• Beka imikhondo ye-multimeter kumaleveli wokuphakela amandla. Odongeni, umane ufake izintambo ezimbotsheni zokuphuma.

Ulindele ukubona inani eliphakathi kuka-120V no-240V, kodwa kuya ngokuthi.

Uma ukufundwa kungalungile, ukunikezwa kwamandla akho kungase kubangele izinkinga. Uma ukufundwa kulungile, qhubeka uhlole amatheminali okukhiphayo we-transformer. Kwenze,

• Xhuma i-transformer kugesi
• Yehlisa ububanzi be-voltage ku-multimeter
• Beka imikhondo ye-multimeter kumatheminali okukhiphayo we-transformer yakho.
• Hlola ukufundwa

Ngokubheka ukufundwa ku-multimeter, uhlola ukuthi umphumela ulungile yini. Lapha ubheka izici ezinconyiwe zokukhishwa kwe-transformer ukuze ufinyelele isiphetho.

Ukuhlola ubuqotho be-Transformer

Ukuhlolwa kobuqotho be-transformer kwenziwa ukuze kuqinisekiswe ukuthi akukho umjikelezo ovulekile noma omfushane kumakhoyili. Usebenzisa lokhu kuhlola lapho i-transformer inqanyulwa ekunikezeni amandla. Wenzani?

• Setha isikali se-multimeter sibe i-Ohm noma i-Resistance. Lokhu kuvame ukuchazwa ngophawu (Ω).
• Beka imikhondo ye-multimeter kumatheminali wokufaka ngayinye ku-transformer yakho.

Lapho i-transformer inomjikelezo omfushane, i-multimeter izonikeza ukufundwa okuphezulu kakhulu noma okungapheli. I-Infinite Reading imelelwa ngu-"OL" okusho ukuthi "Open Loop". 

Uma amatheminali okokufaka ebukeka evamile, uphinda le nqubo kumatheminali okukhiphayo. 

Uma kwenzeka noma iyiphi yalezi zindawo zokugcina inika inani eliphezulu noma elingapheli, i-transformer kufanele ishintshwe. Nansi ividiyo ekhombisa le nqubo.

Indlela Yokwenza Ukuhlolwa Kokumelana Nesiguquli

isiphetho

Ukuxilongwa kwe-Transformer kuyinqubo edinga ukuphathwa ngokucophelela, ikakhulukazi lapho kuhlolwa amatheminali okokufaka nokukhiphayo. 

Kodwa-ke, kufanele uqaphele ukuthi ama-transformer ngokuvamile anesikhathi eside sokuphila. Inkinga ngazo ikhombisa ukungasebenzi kahle kwenye indawo kumjikelezo kagesi.

Kulokhu, kunconywa ukuqapha ama-transformers asanda kufakwa ngemisindo emibi, kanye nokuhlola ukuthi ezinye izingxenye zesifunda, njenge-fuses, zisesimweni esihle.

Imibuzo evame ukubuzwa

Ungazi kanjani ukuthi i-transformer inephutha?

Uma i-transformer inephutha, ungase ubone ukuthi idivayisi ayisebenzi, i-breaker circuit ivala njalo, noma uzwa i-transformer ikhala. Imitha izokusiza ukuthi uphinde uhlole amakhoyili kanye nokufundwa kwawo kwamandla kagesi.

Uzokwenzani ukuze uhlole ukuqhubeka kwe-transformer?

Ukuze uhlole ubuqotho be-transformer, yinqamule bese ubeka ama-probe imitha kumatheminali okokufaka. Uma amatheminali akhipha inani eliphezulu noma elingapheli elithi "OL", lapho-ke akukho ukuqhubeka. Okufanayo kuyiqiniso kumatheminali okukhiphayo.

Kwenzekani uma i-transformer ihluleka?

Lapho i-transformer ihluleka, idivayisi ingase ingasebenzi, noma ungase uzwe imisindo enomsindo noma evungamayo evela ku-transformer.

Kuyini ukumelana kwe-transformer?

Ukumelana kwe-transformer kuncike kudivayisi okuhloswe ngayo amandla. Kufanele uhlole izici ze-transformer ukuze ufinyelele isiphetho.
