Mokhoa oa ho Lekola Transformer ka Multimeter (Mohato oa Mehato e 4)

Li-transformer ke likarolo tsa bohlokoa tsa motlakase tse fetisang matla lipakeng tsa lipotoloho tse peli kapa ho feta. Leha ho le joalo, ka linako tse ling li ka hlōleha 'me tsa baka ho hlōleha ha potoloho. Ka hona, ho bohlokoa haholo ho hlahloba transformer e le hore lisebelisoa tsa hau li sebetse ntle le kotsi ea mollo kapa liketsahalo tse kotsi.

Ho na le mekhoa e fapaneng ea ho lekola li-transformer, 'me e sebetsang ka ho fetesisa ke multimeter ea dijithale. Kahoo, bala 'me u fumane mokhoa oa ho leka transformer ka multimeter! Tataiso ena e tla u nka mohato ka mohato!

Ho Khetholla Mathata a Transformer

Ho na le mekhoa e mengata ea ho tseba hore na transformer ea hau e fosahetse, 'me multimeter ea digital ke e' ngoe ea tsona. DMM ke sesebelisoa se sebetsang ka ho fetisisa sa ho lemoha liphoso tsa transformer, ntle le mosebetsi oa motheo oa ho hlahloba motlakase, hona joale, joalo-joalo Haeba tsohle li tsamaea hantle, u lokela ho fumana liphoso leha e le life tsa transformer le ho ithuta ho li lokisa. e ka sebetsa ka tsela e tloaelehileng hape.

Ka hona, pele u qala ho hlahloba transformer ka multimeter, ho ka ba molemo hore u qale ho tseba lintlha tsa bohlokoa ka li-transformer. Ka hona, o tlameha ho:

Ka mahlo, hlahloba transformer

Sesosa se tloaelehileng sa ho hloleha ha transformer ke ho chesa haholo, ho futhumatsa terata e ka hare ea transformer ho mocheso o phahameng. Ka lebaka leo, transformer kapa sebaka se potolohileng hangata se holofala 'meleng. U se ke ua hlahloba transformer haeba e ruruhile ka ntle kapa e chesitsoe, empa e nke sebaka.

Fumana marang-rang a transformer

Wiring e tlameha ho tšoauoa ka ho hlaka ho transformer. Leha ho le joalo, tsela e bonolo ka ho fetisisa ea ho fumana hore na transformer e hokahane joang ke ho fumana setšoantšo sa potoloho. U ka fumana setšoantšo sa potoloho boitsebisong ba sehlahisoa kapa webosaeteng ea moetsi oa potoloho. (1)

Tseba mahlakore a transformer

Transformer ea 24V e na le lehlakore le ka sehloohong (leqhubu le phahameng) le lehlakore la bobeli (li-voltage tse tlase).

• Lehlakore le ka sehloohong (leqhubu le phahameng) ke mohala oa motlakase oa transformer le khokahanyo ea motlakase ho motlakase oa phepelo, hangata 120 VAC.
• Lehlakore la bobeli (la motlakase o tlase) ke matla a fetoletsoeng ho 24 volts.

Ho transformer e sebelisoang bakeng sa kopo ea 24V, ha ho na motlakase o tobileng pakeng tsa likarolo tse phahameng le tse tlaase.

Mokhoa oa ho lekola Transformer ka Multimeter (Mehato)

Tataisong ena, re tla be re leka 24V transformer mme o tla hloka tse latelang:

• Screwdriver
• multimeter

Kahoo, ho hlahloba motlakase oa motlakase ka multimeter joang? Etsa se latelang:

Mohato oa 1: Tlosa likoahelo tsa motlakase 

Tima matla a potoloho. Tlosa likoahelo tsohle tsa motlakase tse koahelang transformer ka screwdriver. Ke khothaletsa ho hlahloba litaelo tsa moetsi ho netefatsa phihlello ea transformer.

Mohato oa 2: Kenya lithapo ho multimeter

Fetola tlhophiso ea multimeter ho "Ohm", ebe u kenya tlhahlobo e khubelu le e ntšo ho multimeter. Mochine o motšo o kena ka sekoting se tloaelehileng, 'me lipatlisiso tse khubelu li kena ka har'a sokete ea Ohm. Ka mor'a moo, kopanya lipheletsong tsa lithapo tse peli hammoho. E lokela ho bontša zero ohms kapa potoloho e koetsoeng.

Mohato oa 3: Connect Leads ho Main Side 

Kopanya multimeter e lebisa lehlakoreng le phahameng kapa le ka sehloohong la transformer. Methara e tlameha ho khetholla ho bala ho hanyetsa, 'me mofuta oa transformer o sebelisoang potolohong o tla ama ho bala hona. Haeba meter e bontša potoloho e bulehileng kapa khanyetso e sa feleng, ho hlokahala hore u nke sebaka sa transformer e phahameng.

Mohato oa 4: Etsa se tšoanang ka lehlakore la bobeli 

Latela mokhoa o tšoanang mohatong oa 3 bakeng sa likhokahano tse lehlakoreng la motlakase o tlase kapa potolohong ea bobeli. Metara e lokela ho tlaleha tekanyo e nepahetseng ea khanyetso ho ohm bakeng sa lehlakore le ka tlase. Joale, haeba multimeter e bontša ho bala ho sa feleng kapa ho pharaletseng, lehlakoreng le tlaase la motlakase le senyeha ka hare 'me transformer e hloka ho nkeloa sebaka.

 Malebela a mantlha

• Molumo o hlabang kapa o hlabang ke temoso e tloaelehileng ea hore transformer e haufi le ho cha.
• Ha u ama li-probes 'me karolo e le' ngoe feela ea transformer e sa sebetse, u ka 'na ua utloa molumo o hlabang. Tabeng ena ha ho na hona joale e phallang ka transformer 'me e leka ho sebetsa khahlanong le eona.
• U se ke ua nahana hore mahlakoreng a mantlha le a bobeli a transformer a kopantsoe mobung o le mong oa motlakase. Hangata li boleloa ka mabaka a fapaneng. Ka hona, ela hloko ha u etsa litekanyo tse arohaneng.
• U ka boela ua hlahloba botšepehi ba transformer. Ho hlahloba ho tsoela pele ha transformer ho bohlokoa ho bona hore na ho na le tsela ea hore motlakase o fete pakeng tsa libaka tse peli tsa ho kopana. Haeba ho se na tsela ea hona joale, ho na le ntho e sa tsamaeeng hantle ka hare ho transformer ea hau 'me e hloka ho lokisoa.

Litlhokomelo

Ho leka transformer ka mokhoa o sireletsehileng, lintlha tse latelang li tlameha ho tsotelloa:

• Tlosa matla ohle ho tsoa sesebelisoa kapa sesebelisoa pele u etsa liteko. Le ka mohla u se ke ua leka sesebelisoa se hoketsoeng mohloling oa motlakase o kantle.
• Etsa liteko kamehla sebakeng se sireletsehileng, se omeletseng hole le bana le liphoofolo tsa lapeng.
• Ho kopana ka tsietsi le matla a potoloho ha li-circuits li butsoe 'me li matlafalitsoe bakeng sa tlhahlobo ho ka baka ts'okelo ea motlakase kapa tšenyo. Sebelisa feela DMM e lebisang ho ama potoloho.
• Ho sebetsa ka motlakase ho kotsi haholo. Ka hona, e-ba hlokolosi ha u etsa joalo. U se ke ua bulela transformer e nang le lithapo tse robehileng kapa tšenyo e bonahalang, kaha sena se ka lebisa ts'ebetsong ea motlakase.
• Lekola transformer feela haeba u tloaelane le lisebelisoa tsa motlakase 'me u sebelisitse multimeter ho leka voltage, hona joale, le ho hanyetsa holim'a mefuta e mengata ea boleng.

Transformer: e sebetsa joang? (Bonus)

Transformer ke sesebelisoa sa bohlokoa sa motlakase se fetolang voltage ea lets'oao la alternating current (AC). Sena se finyelloa ka ho fetola motlakase oa AC hore e be mats'oao a phahameng kapa a tlase. Sena se bohlokoa hobane se netefatsa phetiso e bolokehileng ea motlakase libakeng tse telele. Ntle le moo, o ka sebelisa transformer ho nyolla kapa ho theola voltage ea lets'oao la AC pele e kena ka mohahong.

Li-transformer li tla ka boholo le litlhophiso tse fapaneng, empa kaofela li sebetsa ka ho theha matla a khoheli a pota-potileng likhoele tse peli tsa terata, tse tsejoang ka hore ke li-winding. Leqhubu le le leng le hoketsoe ka kotloloho mohloling oa AC, joalo ka mohala oa motlakase. Ka lehlakoreng le leng, matsoelintsoeke a mang a hokahantsoe le mojaro oa motlakase, joalo ka tleloubu. Ha hona joale ho feta khoele e le 'ngoe, ho hlahisa matla a khoheli a pota-potileng likhoele ka bobeli. Haeba ho se na likheo lipakeng tsa mapheo ana a mabeli, li tla lula li e-na le polarity e fapaneng, e ’ngoe e lebile leboea ’me e ’ngoe e lebe boroa. Ka hona, transformer e fana ka motlakase o mong.

Primary le Sekondari

Likhoele tsa mantlha le tsa bobeli tsa transformer ke likhoele tsa terata tse hlahisang hona joale. Coil e ka sehloohong e hokahane le mohala oa motlakase 'me khoele ea bobeli e hokahane le mojaro oa motlakase. U ka fetola motlakase oa motlakase oa transformer ka ho fetola palo ea hona joale ka mokhoa o mong le o mong oa moea. (2)
