How kutarisa transformer multimeter? kurayira

Kakawanda unofanira uzive kare chete mubvunzo sei kuona transformer. Pashure pezvose, kana akatadza, kana kusagadzikana achava zvakaoma kutarisa kwemhosva midziyo kukundikana. Iri nyore zvemagetsi zano rinogona rokuongorora munhu kwakajairika multimeter. Ngationei kuti kuita izvozvo.

Chii midziyo?

How kutarisa transformer, kana usingazive nechivako yawo? Funga musimboti chiito uye dzakasiyana-siyana nyore michina. On the rinobva chinoumba zvemapuranga mhangura waya Coils yakanatsa mupanda kuitira kuti mhedziso vakasara kuti kuerera uye yechipiri ichitenderera.

Energy kuchinjirwa kune yechipiri ichitenderera rinoitwa munyika contactless nenzira. Kune kare anenge pachena sei kuti kutarisa transformer. Saizvozvowo prozvanivat kwakajairika inductance ohmmeter. The Coils dzinoumba nemishonga kuti kuyerwa. Zvisinei, nzira iyi rinoshanda apo kubaya ukoshi anozivikanwa. Zvechokwadi, kuti kurwisa dzingasiyana kana pasi somugumisiro kudziyisa. Uku kunonzi interturn pfupi vematunhu.

mudziyo akadaro haangaiti ngaateme bhuku voltage uye iyezvino. Ohmmeter vachatitaka remudunhu rakazaruka chete kana wafa pfupi. Nokuti mamwe chirwere ishandiswe earthing chete ohmmeter. How kutarisa transformer windings asingazivi zvakawanikwa?

Izvi pakutsvaga ukobvu of exiting waya. Kana transformer iri shoma, asi chinouraya conductors mutobvu achava mukobvu. Uye maererano nekusiyana: iri danho-up chiyamuro waya mukobvu. Kana vaviri ichitenderera goho, pakukora zvingava zvakafanana, zvinofanira kurangarirwa nezvazvo. Nzira yakanakisisa kuona pamapepa aya uye kuwana midziyo nokurondedzerwa.

mhando

Transformers akakamurwa inotevera mapoka:

• Richikwidibira uye kurera.
• Power kazhinji kushumira kuderedza pomugove voltage.
• Current transformers nokuti unokupai kugara kuitika kuna mutengi wayo chengetedzo mukati akafanorongerwa siyana.
• Single- uye multi-danho.
• Welding zvinangwa.
• Kufamba kweropa.

Zvichienderana chinangwa michina iri achinja uye nheyo tinosvika kuna mubvunzo sei kuona transformer. Multimeter zvinobvira kungorira maduku kadikidiki chete mudziyo. Power michina kare zvinoda yakasiyana ainoita troubleshooting.

chamazuva nzira

ohmmeter nzira nechirwere kuchabatsira pamwe mubvunzo sei kuti ritsigire simba transformer. Prozvanivat nemishonga pakati pakatanga imwe ichitenderera. Saka kuvimbika kondakita yakatarwa. Asati muviri kuti tiite inspections pamusoro kusavapo kabhoni deposits, sagging nokuda kudziyisa michina.

Next, uyere kuitika anokoshesa ohms uye enzanisa navo pasipoti. Kana avo vasiri kuwanikwa, zvinoda mamwe Diagnostics kwakapa. Prozvonit akakurudzira ose goho mudziyo kuti simbi kwedzimba, izvo zvakabatanidzwa pasi.

Vasati nokuyerwa, patsanura zvose kumagumo transformer. Patsanura kubva cheni, uye vari pachii yavo vakachengeteka. Uyewo tarisa Kuwanikwa wemagetsi redunhu, iro kazhinji aripo vemazuva yokutevedzera simba. Zvinofanira kuva vypayat vasati vachiongorora.

Magumo kurwisa inoratidza kuputira yose. Tsika ane kilohms shoma kare vasanyumwa pamusoro Kuparara redzimba. Kungavawo nokuda vaunganidza tsvina, guruva kana mwando mudenga pakaputsika mudziyo.

kurarama

Miedzo vakatakudzwa kubva aine simba iri kusvitsa kana paine mubvunzo pamusoro sei kuona transformer interturn remudunhu pfupi. Kana tichiziva kukosha romugove voltage mudziyo, iyo yakagadzirirwa kuti transformer, kuti voltmeter kuyera kukosha idling. Kureva, kutungamirira waya dziri mudenga.

Kana voltage akasiyana chezita, zvinonzi akagumisa ichitenderera redunhu pfupi iri windings. Kana panguva mashandiro anzwike crackle, arcing, kwakadaro transformer nani kudzima. Hazvina hunonyengera. Pane tolerances ari kuyerwa:

• Nokuti voltage tsika dzinosiyana ne 20%.
• Nokuti kurwisa zvazvingava zviri kuwanda tsika 50% of pasipoti.

metering ammeter

Ngatitaurei kunzwisisa sei kuongorora kuitika transformer. Rinowanikwawo hochekoche yakazara kana achizviita. Zvakakosha kuti magetsi mutengo haidereri kupfuura chezita. ammeter kuyerwa kuitwa mukuru wedunhu uye yechipiri.

Current zvinoratidza zvichienzaniswa yechipiri mudunhu chepuraimari. More chaizvo, yakakamukana kutanga tsika akayera pamusoro yechipiri ichitenderera. Kushandurwa reshiyo inofanira kutorwa kubva mubhuku rekushandisa, uye kuenzanisa neavo yaunganidzwa Masvomhu. Migumisiro vanofanira kuva zvakafanana.

The transformer razvino haigoni kuyerwa panguva simbe. Kurutivi yechipiri iyi inogona kuumbwa kukwirira voltages kuti anogona kukuvadza kuputira. Unofanirawo kuchengeta polarity, izvo huchachinja oparesheni yose wiring.

Common Problems

Usati tarisa transformer microwave, ipai kakawanda breakdowns akasiyana kuti wakaiswa pasina multimeter. Kazhinji simba mano vanokundikana nokuda dunhu pfupi. It chinosimbiswa Kuedzwa mudunhu mapuranga, connectors, kubatana. Kuderera zvokuimba kukuvadzwa kunoitika transformer redzimba uye core.

Zvokuimba kusakara pakati yeimwe ari transformer zviteshi pamusoro kutamira muchina kunoitika. Large zvitengeswa ichitenderera zvinoda kugara kutonhora. In yayo kusavapo, anogona overheat uye zvinonyauka yacho kuputira.

TDKS

Tinotarisa kuti aone wako kufamba kweropa transformer. An ohmmeter anogona hwaizogadzwa chete kuvimbika windings. The kunyatsoshanda of mudziyo chinosimbiswa unobatanidza dunhu, sezvamakaropafadzwa capacitor rinobatanidzwa, mutoro uye nokurira jenareta.

At nokutanga chikuru ichitenderera kupomba chiratidzo kuwanda kubva 20 kusvika 100 kHz. Panguva yechipiri ichitenderera kuti kuyerwa zvikuru oscilloscope. Kumisa pamberi kufamba kweropa kusarurama. Kana vasiri, kuti vafunga pamusoro mudziyo yakakodzera.

Waveform kusarurama vanoti propped windings. Repairing mano kwakadaro hakuna inokurudzirwa tisingatungamirirwi. Vakanga akamisa murabhoritari. Pane zvimwe zvirongwa dzipupurire kupomba transformers, apo akaongorora kuvapo resonance Coils. Its asipo kunoratidza atadze kushanda zvakanaka pamusoro mudziyo.

Zvinogonekawo kuenzanisa chimiro pulses vaipa kune chikuru ichitenderera uye yechipiri ranyuka. Kutsauka chimiro anovataurirawo transformer atadze kushanda zvakanaka.

akawanda windings

Nokuti kurwisa kuyerwa vakasununguka kumigumo magetsi kubatana. Sarudzai chero chirwere uye akayera hama kune dzimwe nemishonga yose. Zvinokurudzirwa kuti vanyore kukosha uye chiratidzo-vaedzwa mazano.

Saka tinogona kuona mhando ichitenderera kubatana: pamwe paavhareji zvakawanikwa, pasina kwavari, vakawanda kubatana pfungwa. More kazhinji yoga windings kubatana. Nokuyerwa ngakuitwe chete nemumwe tambo.

Kana paine zvakafanana nguva, kurwisa nezviyero pakati ose conductors. Two pakati ichitenderera chinouraya achava netsika pakati waya matatu chete. Kugumisa Several inowanikwa transformers zvakagadzirirwa kushanda wandei network sangano 110 kana 220 volts.

Diagnostics nuances

Nemahon'era kana transformer romuzvarirwo kana misi mudziyo. Chete sparking uye kwomurazvo zvinoratidza dambudziko. Kazhinji, uye kudziyisa Coils - iri dzose nokushanda transformer. Kakawanda richiwanika munyika richikwidibira namano.

Resonance kunogona akasika kana vibrating muviri transformer. Ipapo anofanira nyore kugadzirisa insulating zvinhu. Basa windings dzinosiyana yekudyidzana ne-siyana akasungirirwa kana tsvina vokukurukura. matambudziko mazhinji kugadziriswa nokutorera simbi chipenye uye akamonera pamwe zvakawanikwa itsva.

Kana kuyera voltage uye iyezvino tsika vanofanira kufunga ambient tembiricha, kukura uye hunhu mutoro. Kudzora romugove voltage Zvinokoshawo. kakawanda kubatana bvunzo kunodiwa. Asian uye American rwokugadzira rakagadzirirwa 60 Hz, zvichiguma zvakare pasi goho tsika.

Tampering kubatana zviri transformer kungaita atadze kushanda zvakanaka pamusoro mudziyo. Chero zvazvingava asina chokuita kuti windings ari DC voltage. The majana nokukurumidza oplavyatsya kudaro. Zvakarurama kuyerwa uye nomazvo kubatana haangatenderi chete kuwana mhosva kukundikana, asi anogona kubvisa pawo nyarara nenzira.
