Maitiro ekuyedza transformer ine multimeter
Zviri mukati
Kubva pamayuniti mahombe patambo dzemagetsi kusvika kumayunitsi madiki mumidziyo yakaita semachaja efoni, matransformer anouya mune ese maumbirwo nemasaizi.
Nekudaro, ivo vanoita basa rimwe chete, kuve nechokwadi chekuti zvishandiso zvako nemidziyo zvinopihwa chaiyo huwandu hwemagetsi vanofanira kushanda nemazvo.
Nekudaro, senge chero imwe yemagetsi mudziyo, transformers kukudziridza zvikanganiso.
Kuvatsiva kunogona kuve sarudzo yausingadi kushandisa, saka unoongorora sei transformer uye kuona mhinduro yakakodzera yainoda?
Ichi chinyorwa inopa mhinduro kune izvi, nokuti tinopa ruzivo pamusoro pekuti transformer inoshanda sei, uye nezve nzira dzakasiyana-siyana dzekuiongorora kune zvikanganiso.
Pasina imwezve ado, ngatitangei.
Chii chinonzi transformer
Transformer chinhu chinoshandura chiratidzo chealternating current (AC) kubva pahigh voltage kuenda pa low voltage or versation.
Iyo transformer inoshandura kune yakaderera inogona mutsauko inonzi nhanho pasi transformer uye ndiyo yakajairika kune maviri ayo anotishandira zuva nezuva.
Magetsi ekudzika-pasi pamatambo emagetsi anodzika zviuru zvemagetsi kusvika pazasi voltage 240V yekushandisa pamba.
Zvishandiso zvedu zvakasiyana senge malaptop ekubatanidza, machaja efoni uye kunyange mabhero epagonhi anoshandisa matransformer avo.
Ivo vanoderedza voltage kusvika ku2V chete kuti mudziyo urambe uchishanda.
Imwe nzira kune iyi inonzi nhanho-up transformer uye inowanzoshandiswa pakati pemagetsi emagetsi kuwedzera simba rekugovera.
Zvisinei, isu tinonyanya kufarira nhanho-pasi transformers, sezvo izvi ndizvo zvatinowanzobata nazvo. Asi vanoshanda sei?
Mashandiro Anoita Pazasi Transformers
Nhanho-pasi ma transformer anoshandisa makoiri maviri, anozivikanwawo semamhepo. Aya ndiwo ekutanga coil uye yechipiri coil.
Iyo yekutanga coil ndiyo yekuisa coil inogamuchira ikozvino kubva kune AC voltage sosi senge tambo yemagetsi.
Iyo yechipiri coil ndiyo inobuda coil inotumira yakaderera masaini kumidziyo yemumba mako.
Imwe neimwe coil inokuvadzwa pamusimboti uye kana ikozvino inopfuura nepakati pekutanga coil, iyo magineti inogadzirwa iyo induces ikozvino mune yechipiri coil.
Pakudzika pasi ma transformer, iyo yekutanga mhepo inotenderedza ine matendeuko akawanda kupfuura yechipiri mhepo. Pasina kupinda muhuwandu, huwandu hwema windings hunoenderana zvakananga kune voltage yemagetsi emagetsi (EMF) anogadzirwa necoil.
Kubva ~ V
Ngatishevedzei mhepo yekupinza yecoil W1, inobuda mhepo yecoil W2, iyo yekuisa voltage E1 uye inobuda voltage E2. Nhanho-pasi ma transformer ane akawanda matende pacoil yekupinza pane inobuda coil.
P1 > P2
Izvi zvinoreva kuti voltage yeinobuda (yechipiri) coil yakaderera pane voltage yekoiri yekupinza.
E2 < E1
Saka iyo yakakwira AC voltage inoshandurwa kuita yakaderera. Mukuwedzera, ikozvino yakakwirira inopfuudzwa kuburikidza neyechipiri coil kuenzanisa capacitance yezvose zviri zviviri windings.
Transformers hazvisi zvese, asi irwo ruzivo rwekutanga rwauchazoda usati waedza transformer yako.
Kana iwe uchifungidzira kuti transformer yako haisi kushanda zvakanaka, iwe unongoda multimeter kuti uiongorore.
Maitiro ekuyedza transformer ine multimeter
Kuti uedze transformer, iwe unoshandisa multimeter kuyedza iyo AC voltage kuverenga pane yekuisa sosi uye inobuda materminal nepo transformer yakabatana. Iwe zvakare unoshandisa multimeter kuyedza kuenderera kweshanduko kana isina kubatana kune chero simba sosi. .
Vanozotsanangurwa zvinotevera.
Input and output tests
Kazhinji, bvunzo iyi inongoitwa chete painobuda materminal e transformer.
Nekudaro, kuti uve nechokwadi chekuverenga chaiko kubva kune zvinobuda zviteshi, iwe unofanirwa kuve nechokwadi chekuti voltage inoshandiswa kwavari ndeyechokwadi. Ndiko kusaka uri kuyedza yako yekuisa sosi.
Kune midziyo yemumba, iyo yekuisa chiratidzo masosi inowanzova zvigadziko mumadziro. Iwe unoda kutarisa kuti vanopa iyo chaiyo huwandu hwemagetsi.
Kuti uite izvi, tevera matanho aya
- Isa iyo multimeter ku200 VAC.
- Isa iyo multimeter inotungamira pane magetsi anotungamira. Kumadziro emadziro, unongopinza waya mumaburi ekubuda nawo.
Iwe unotarisira kuona kukosha pakati pe120V ne240V, asi zvinoenderana.
Kana kuverenga kusiri iko, magetsi ako anogona kunge ari kukonzera matambudziko. Kana kuverenga kwacho kwakaringana, enderera utarise materminal akabuda etransformer. Zviite,
- Batanidza transformer kune magetsi
- Deredza huwandu hwemagetsi pane multimeter
- Isa iyo multimeter inotungamira pane inobuda materminal e transformer yako.
- Tarisa kuverenga
Nekutarisa kuverenga pane multimeter, unotarisa kana mhedzisiro yacho ndeyechokwadi. Pano iwe uri kutarisa kune yakakurudzirwa kuburitsa maitiro eiyo transformer kutora mhedziso.
Transformer kutendeseka cheki
Cheki yekutendeseka yetransformer inoitwa kuitira kuti ive nechokwadi chekuti hapana dunhu rakavhurika kana pfupi mumakoiri. Iwe unomhanyisa bvunzo iyi kana transformer yabviswa kubva kune magetsi. Uri kuitei?
- Isa iyo multimeter chiyero kuOhm kana Resistance. Izvi zvinowanzoratidzwa nechiratidzo (Ω).
- Isa inotungamira yemultimeter pane yega yega materminal ekuisa pane yako transformer.
Iko iyo transformer ine dunhu diki, iyo multimeter ichapa yakakwira zvakanyanya kana isingaperi kuverenga. Infinite Reading inomiririrwa ne”OL” inomirira kuti “Open Loop”.
Kana materminal ekuisa achitaridzika seakajairwa, unodzokorora maitiro aya kune anobuda materminal.
Muchiitiko icho chimwe chezviteshi izvi zvinopa kukosha kwepamusoro kana kusingagumi, transformer inofanira kuchinjwa. Heino vhidhiyo inoratidza maitiro aya.
mhedziso
Transformer diagnostics inzira inoda kubatwa nehungwaru, kunyanya kana uchitarisa zvekupinza uye zvinobuda.
Nekudaro, iwe unofanirwa kucherechedza kuti ma transformer anowanzo ane hupenyu hurefu. Dambudziko navo rinoratidza kusashanda kune imwe nzvimbo munharaunda yemagetsi.
Panyaya iyi, zvinokurudzirwa kutarisa vashanduri vachangobva kuiswa nokuda kwekunzwa kwakashata, uyewo kutarisa kuti zvimwe zvikamu zvedunhu, zvakadai semafusi, zviri mumamiriro akanaka.
Inowanzobvunzwa Mibvunzo
Nzira yekuziva sei kana transformer yakashata?
Kana iyo transformer yakanganisa, unogona kuona kuti chigadziri hachishande, mutsigiri wedunhu anogara achidzima, kana kuti unonzwa kurira kweshanduko. Iyo mita ichakubatsirawo kuti uite mamwe macheki pamakoiri uye kuverenga kwavo kwemagetsi.
Chii chauchaita kuti uedze kuenderera kwetransformer?
Kuti utarise kutendeseka kweshanduro, bvisa iyo uye isa ma meter probes pamagetsi ekupinza. Kana materminals aburitsa yakakwira kana isingaperi "OL" kukosha, saka hapana kuenderera. Izvi zvakafanana kune zvinobuda terminals.
Chii chinoitika kana transformer ikakundikana?
Kana iyo transformer ikakundikana, mudziyo unogona kusashanda, kana iwe unogona kunzwa kuhon'era kana kuhon'era kunobva kune transformer.
Chii chinopikisa transformer?
Kupokana kwetransformer kunoenderana nechishandiso icho chinoitirwa simba. Iwe unofanirwa kutarisa maitiro eiyo transformer kuti uwane mhedzisiro.
