Izici zomkhiqizo kanye nesimiso

I-LCWD-35 transformer yamanje ihlangene, incane ngosayizi futhi ilula ngesisindo.Ingxenye engenhla iyi-winging eyinhloko, ingxenye engezansi iwukuphenduka kwesibili, i-bushing igxiliwe esisekelweni, phezulu kwe-bushing ifakwe isilondolozi samafutha, i-winging eyinhloko iphuma ezinhlangothini zombili zodonga lwekhabhinethi, kanye netheminali yokuqala ebhalwe ukuthi P1 Umkhono omncane we-porcelain usetshenziselwa ukufaka udonga lwekhabhinethi, futhi isiphetho se-P2 sixhunywe ngokuqondile odongeni lwekhabhinethi.Ingaphambili lesilondolozi sikawoyela lifakwe izikali zikawoyela ezibonisa amazinga okushisa ahlukene.

Isimiso:
Emigqeni yokukhiqiza amandla, isiteshi esincane, ukudluliselwa, ukusatshalaliswa kanye nokusetshenziswa, okwamanje kuyahlukahluka kakhulu, kusukela kuma-ampere ambalwa kuya ezinkulungwaneni zezinkulungwane zama-ampere.Ukuze kube lula ukukala, ukuvikela kanye nokulawula, idinga ukuguqulwa ibe yamanje efanayo ngokuqhathaniswa.Ngaphezu kwalokho, i-voltage kulayini ngokuvamile iphakeme kakhulu, njengokulinganisa okuqondile, okuyingozi kakhulu.I-transformer yamanje idlala indima yokuguqulwa kwamanje kanye nokuhlukaniswa kukagesi.
Kuma-ammeters ohlobo lwe-pointer, iningi lama-currents wesibili ama-transformer amanje asezingeni le-ampere (njenge-5A, njll.).Kumathuluzi edijithali, isignali eyisampula ngokuvamile isezingeni le-milliamp (0-5V, 4-20mA, njll.).I-current yesibili ye-miniature transformer yamanje i-milliampere, esebenza ngokuyinhloko njengebhuloho phakathi kwe-transformer enkulu kanye nesampula.
Ama-transformers amanje amancane abizwa nangokuthi "i-instrument transformers yamanje".("Isiguquli samanje sensimbi" sinencazelo yokuthi siyi-multi-current ratio enemba isiguquli samanje esisetshenziswa elabhorethri, ngokuvamile esetshenziselwa ukunweba ububanzi bezinsimbi.)
Ngokufanayo ne-transformer, i-transformer yamanje nayo isebenza ngokuvumelana nesimiso sokungeniswa kwe-electromagnetic.I-transformer iguqula i-voltage futhi i-transformer yamanje iguqule yamanje.Ukusonteka kwe-transformer yamanje exhunywe ku-current elinganisiwe (inombolo yokujika i-N1) ibizwa ngokuthi i-primary winding (noma i-primary winding, i-primary winding);ukujikajika okuxhunywe kuthuluzi lokulinganisa (inombolo yokujika i-N2) kubizwa ngokuthi ukujikajika kwesibili (noma ukujikajika kwesibili).ukujikajika, ukujika kwesibili).
Isilinganiso samanje se-primary winding current i-I1 kuya ku-I2 yokujika kwesibili kwe-transformer yamanje ibizwa ngokuthi isilinganiso samanje sangempela K. Isilinganiso samanje se-transformer yamanje uma isebenza ngaphansi kwamandla amanje alinganiselwe kuthiwa isilinganiso samanje esilinganiselwe se-transformer yamanje. , evezwe u-Kn.
Kn=I1n/I2n
Umsebenzi we-transformer yamanje (i-CT ngamafuphi) ukuguqula i-primary current enenani elikhulu ibe i-current yesibili enenani elincane ngokusebenzisa isilinganiso esithile sokuguqulwa, esisetshenziselwa ukuvikela, ukulinganisa nezinye izinjongo.Isibonelo, i-transformer yamanje enesilinganiso se-400/5 ingaguqula i-current yangempela ye-400A ibe yamanje ye-5A.

Ukuphatha Inkinga ye-Transformer nohlelo lokuhleleka

Ukusingathwa kwezinkinga ezihlobene ne-Transformer:
Ukwehluleka kwamanje kwe-transformer kuvame ukuhambisana nemisindo nezinye izenzakalo.Lapho isifunda sesibili sivulwa ngokuzumayo, kukhiqizwa amandla aphakeme aphezulu ku-coil yesibili, futhi inani layo eliphakeme lingafinyelela ngaphezu kwama-volts ayizinkulungwane ezimbalwa, okubeka engozini impilo yabasebenzi nokuphepha kwemishini kusekethe yesibili, futhi I-voltage ephezulu ingabangela umlilo we-arc.Ngesikhathi esifanayo, ngenxa yokwanda okubukhali kwe-magnetic flux ku-iron core, ifinyelela esimweni esiphezulu sokugcwala.Ukulahlekelwa okuyisisekelo nokushisa kubi kakhulu, okungase kulimaze ukuphenduka kwesibili kwe-rheological.Ngalesi sikhathi, igagasi elingelona i-sinusoidal libangelwa ukwanda kwe-magnetic flux density, okwenza ukudlidliza kweshidi lensimbi ye-silicon kungalingani ngokwedlulele, okuholela emsindweni omkhulu.
1. Ukuphathwa kwe-transformer yamanje kusekethe evulekile Uma iphutha elinjalo lenzeka, umthwalo kufanele ugcinwe ungashintshiwe, idivayisi yokuvikela okungenzeka ingasebenzi kahle kufanele ivaliwe, futhi izisebenzi ezifanele kufanele zaziswe ukuze ziqede ngokushesha.
2. Ukwelashwa kwe-transformer yamanje yokunqanyulwa kwesekethe yesibili (i-open circuit) 1. Isenzakalo esingavamile:
a.Inkomba ye-ammeter yehlela ku-zero, inkomba yamamitha wamandla asebenzayo futhi asebenzayo iyancipha noma i-oscillates, futhi imitha yehora le-watt ijikeleza kancane noma ima.
b.Isexwayiso sepuleti lokukhanya lokunqamula okuhlukile.
c.I-transformer yamanje yenza imisindo engavamile noma ikhiqize ukushisa, ibheme noma ikhiphe amatheminali esibili, izinhlansi, njll.
d.Idivayisi yokuvikela i-relay yenqaba ukwenza okuthile, noma ukungasebenzi kahle (lesi sigameko sitholakala kuphela uma i-breaker circuit ihambe ngephutha noma yenqaba ukukhubeka futhi ibangele uhambo lwe-leapfrog).
2. Ukuphatha okuhlukile:
a.Ngokushesha bika uphawu kushejuli okungeyalo.
b.Ngokwalesi senzakalo, yahlulela ukuthi i-transformer yamanje yesifunda sokulinganisa noma isifunda sokuvikela sivuliwe.Ukuvalwa kokuvikela okungase kubangele ukusebenza okuyiphutha kufanele kucatshangelwe ngaphambi kokulahlwa.
c.Uma uhlola isifunda sesibili se-transformer yamanje, kufanele ume phezu kwe-insulating pad, unake ukuphepha komuntu siqu, futhi usebenzise amathuluzi okuvikela afanelekayo.
d.Lapho isifunda sesibili se-transformer yamanje sivulekile ukudala umlilo, amandla kufanele anqunywe kuqala, bese umlilo ucishwe ngendwangu eyomile ye-asbestos noma isicishamlilo esomile.
3. Iphutha lamanje lomzimba we-transformer Uma iphutha lamanje le-transformer linenye yalezi zimo ezilandelayo, kufanele limiswe ngokushesha:
a.Kunomsindo ongavamile kanye nokushisa ngokweqile ngaphakathi, okuhambisana nentuthu kanye nephunga elishisayo.b.Ukuvuza okukhulu kwamafutha, i-porcelain eyonakele noma into yokukhishwa.
c.Umlilo womjovo wamafutha noma into yokugeleza kweglue.
d.Ukwelulwa kwesandisi sensimbi kulidlula ngokuphawulekayo inani elishiwo ezingeni lokushisa elizungezile.

Uhlelo lwe-oda:
1. Nikeza umdwebo wohlelo lwezintambo, uhlelo lokusebenza kanye nomdwebo wesistimu, i-voltage elinganiselwe, yamanje elinganiselwe, njll.
2. Izidingo zokulawula, ukulinganisa kanye nemisebenzi yokuvikela kanye nezinye izisetshenziswa zokukhiya nezizenzekelayo.
3. Uma i-transformer isetshenziswa ezimweni ezikhethekile zemvelo, kufanele ichazwe ngokuningiliziwe lapho iyala.
4. Uma ezinye izesekeli noma ngaphezulu kanye nezingxenye ezisele zidingeka, uhlobo nenani kufanele kuphakanyiswe.
