Mokhoa oa ho lekola transformer ka multimeter
Tse ka hare
Ho tloha ho li-unit tse kholo lithapong tsa motlakase ho isa ho tse nyane ka har'a lisebelisoa tse kang tjhaja ea mohala, li-transformer li tla ka libopeho le boholo bo fapaneng.
Leha ho le joalo, li etsa mosebetsi o tšoanang, li netefatsa hore lisebelisoa tsa hau le lisebelisoa tsa hau li fanoa palo e nepahetseng ea motlakase ba lokela ho sebetsa ka nepo.
Leha ho le joalo, joalo ka lisebelisoa tse ling tsa elektroniki, li-transformer hlahisa mefokolo.
Ho li nkela sebaka e ka 'na ea e-ba khetho eo u sa batleng ho e sebelisa, joale u ka hlahloba transformer joang le ho fumana tharollo e nepahetseng eo e e hlokang?
Sengoloa sena e fana ka likarabo ho sena, hobane re fana ka tlhahisoleseding mabapi le hore na transformer e sebetsa joang, le ka mekhoa e sa tšoaneng ea ho e hlahloba bakeng sa liphoso.
Ntle le ho feta, a re qaleng.
Transformer ke eng
Transformer ke sesebelisoa se fetolang lets'oao la alternating current (AC) ho tloha ho voltage e phahameng ho ea ho low voltage kapa ka tsela e fapaneng.
Transformer e fetolelang phapang e fokolang ea bokhoni e bitsoa step down transformer 'me ke eona e tloaelehileng ho tse peli tse re sebeletsang letsatsi le leng le le leng.
Li-transformer tse theohang tlase lithapong tsa motlakase li theola likete tsa voltage ho ea tlase voltage 240V bakeng sa tšebeliso ea lapeng.
Lisebelisoa tsa rona tse fapaneng joalo ka likhokahanyo tsa lilaptop, li charger tsa mehala esita le litloloko tsa mamati li sebelisa li-transformer tsa tsona.
Ba fokotsa motlakase ho 2V feela ho boloka sesebelisoa se sebetsa.
Mokhoa o mong ho tsena o bitsoa step-up transformer 'me hangata e sebelisoa lifemeng tsa motlakase tse bohareng ho eketsa matla a ho ajoa.
Leha ho le joalo, re thahasella haholo li-transformer tse theoha, kaha sena ke seo re atisang ho sebetsana le sona. Empa li sebetsa joang?
Mokhoa oa ho theoha ha li-transformers li sebetsa joang
Li-transformer tse theohang fatše li sebelisa likhoele tse peli, tse tsejoang hape e le li- windings. Tsena ke coil ea mantlha le coil ea bobeli.
Coil ea mantlha ke khoele e kenang e amohelang hajoale ho tsoa mohloling oa motlakase oa AC joalo ka mohala oa motlakase.
Khoeli ea bobeli ke khoele ea tlhahiso e romellang matšoao a tlase ho lisebelisoa tse ka tlung ea hau.
Khoele e 'ngoe le e' ngoe e etsoa mokokotlong 'me ha hona joale e feta ka khoele e ka sehloohong, ho bōptjoa matla a khoheli a susumetsang hona joale ho coil ea bobeli.
Ho li-transformer tse theohileng, moea oa mantlha o na le mothinyeho o mongata ho feta oa bobeli. Ntle le ho kena lintlheng, palo ea li-winding e lekana ka ho toba le motlakase oa motlakase oa motlakase (EMF) o hlahisoang ke khoele.
Ho tloha ~ V
Ha re bitse moea o kenang oa coil W1, phepelo ea coil W2, motlakase oa ho kenya E1 le motlakase oa tlhahiso E2. Li-transformer tse theohang li na le li-coil tse ngata tse kenyang letsoho ho feta coil e hlahisoang.
P1 > P2
Sena se bolela hore motlakase oa coil (ea bobeli) o tlase ho feta motlakase oa coil ea ho kenya.
E2 <E1
Kahoo motlakase o phahameng oa AC o fetoloa ho ba tlase. Ho phaella moo, motlakase o phahameng o fetisoa ka coil ea bobeli ho leka-lekanya bokhoni ba mapheo a mabeli.
Li-transformer ha se ntho e 'ngoe le e' ngoe, empa ke tsebo ea mantlha eo u tla e hloka pele u leka transformer ea hau.
Haeba u belaela hore transformer ea hau ha e sebetse hantle, u hloka feela multimeter ho e hlahloba.
Mokhoa oa ho lekola transformer ka multimeter
Ho leka transformer, o sebelisa multimeter ho lekola lipalo tsa motlakase oa AC mohloling oa ho kenya le liteishene tsa tlhahiso ha transformer e ntse e hokahantsoe. U boetse u sebelisa multimeter ho lekola ho tsoela pele ha transformer ha e sa hokahane le mohloli ofe kapa ofe oa matla. .
Li tla hlalosoa nakong e tlang.
Liteko tsa ho kenya le ho tsoa
Ka tloaelo, tlhahlobo ena e etsoa feela ho li-terminals tsa tlhahiso ea transformer.
Leha ho le joalo, ho etsa bonnete ba hore ho baloa ka nepo ho tsoa li-terminals tsa tlhahiso, u tlameha ho etsa bonnete ba hore motlakase o sebelisoang ho tsona le ona o nepahetse. Ke kahoo o lekang mohloli oa hau oa ho kenya.
Bakeng sa lisebelisoa tsa ntlo, mehloli ea lipontšo tsa ho kenya hangata ke likoti marakong. U batla ho hlahloba hore na ba fana ka palo e nepahetseng ea motlakase.
Ho etsa sena, latela mehato ena
- Beha multimeter ho 200 VAC.
- Beha lits'oants'o tsa multimeter holim'a lisebelisoa tsa motlakase. Bakeng sa li-outlet tsa lebota, o kenya feela likhoele ka har'a masoba a tsoang.
U lebeletse ho bona boleng pakeng tsa 120V le 240V, empa ho itšetlehile ka eona.
Haeba lipalo li sa nepahala, phepelo ea hau ea motlakase e ka baka mathata. Haeba lipalo li nepahetse, tsoela pele ho hlahloba li-terminals tsa tlhahiso ea transformer. E etse,
- Hokela transformer ho phepelo ea motlakase
- Fokotsa lebelo la motlakase ho multimeter
- Beha li-multimeter lead ho li-terminal tsa tlhahiso ea transformer ea hau.
- Sheba lipalo
Ka ho sheba lipalo ho multimeter, u hlahloba hore na sephetho se nepahetse. Mona u shebile litšobotsi tse khothaletsoang tsa transformer ho fihlela qeto.
Ho hlahloba botšepehi ba Transformer
Ho hlahlojoa botšepehi ba transformer ho etsoa e le ho etsa bonnete ba hore ha ho na potoloho e bulehileng kapa e khutšoanyane ka har'a li-coil. U etsa tlhahlobo ena ha transformer e khaotsoe phepelong ea motlakase. U ntse u etsang?
- Beha sekala sa multimeter ho Ohm kapa Resistance. Hangata sena se hlalosoa ka letšoao (Ω).
- Beha li-lead tsa multimeter ho e 'ngoe le e' ngoe ea li-terminals tsa ho kenya ho transformer ea hau.
Moo transformer e nang le potoloho e khutšoanyane, multimeter e tla fana ka lipalo tse phahameng haholo kapa tse sa feleng. Infinite Reading e emetsoe ke "OL" e emelang "Open Loop".
Haeba li-terminals tsa ho kenya li shebahala li tloaelehile, u pheta mokhoa ona bakeng sa li-terminals tsa tlhahiso.
Haeba e 'ngoe ea li-terminals tsena e fana ka boleng bo phahameng kapa bo sa feleng, transformer e tlameha ho nkeloa sebaka. Mona ke video e bontšang mokhoa ona.
fihlela qeto e
Tlhahlobo ea Transformer ke mokhoa o hlokang ho sebetsoa ka hloko, haholo ha ho hlahlojoa li-terminals tsa ho kenya le ho tsoa.
Leha ho le joalo, o lokela ho hlokomela hore hangata li-transformer li na le nako e telele ea bophelo. Bothata ka bona bo bontša ho se sebetse kae-kae potolohong ea motlakase.
Tabeng ena, ho kgothaletswa ho shebella li-transformer tse sa tsoa kenngoa bakeng sa melumo e mebe, hammoho le ho hlahloba hore na likarolo tse ling tsa potoloho, tse kang fuse, li boemong bo botle.
Lipotso tse atisang ho botsoa
U ka tseba joang haeba transformer e fosahetse?
Haeba transformer e fosahetse, u ka 'na ua ba le phihlelo ea hore sesebelisoa ha se sebetse, mochine oa potoloho o lula a tima, kapa u utloa molumo oa transformer. Metara e tla boela e u thuse ho etsa licheke tse ling ho li-coil le lipalo tsa tsona tsa motlakase.
U tla etsa'ng ho leka ho tsoela pele ha transformer?
Ho hlahloba botšepehi ba transformer, e hakolle 'me u behe lisebelisoa tsa meter holim'a li-terminals tsa ho kenya. Haeba li-terminals li hlahisa boleng bo phahameng kapa bo sa feleng ba "OL", joale ha ho na tsoelo-pele. Ho joalo le ka li-terminals tsa tlhahiso.
Ho etsahala'ng ha transformer e hlōleha?
Ha transformer e hlōleha, sesebelisoa se ka 'na sa se ke sa sebetsa, kapa u ka utloa ho lla kapa ho lla ha molumo o tsoang ho transformer.
Ho hanyetsa ha transformer ke eng?
Ho hanyetsa ha transformer ho itšetlehile ka sesebelisoa seo se reretsoeng ho se matlafatsa. U tlameha ho hlahloba litšobotsi tsa transformer ho fihlela qeto.
