Isizathu sokuthi kungani i-iron core idinga isisekelo esincane uma ijwayelekile

Ngesikhathi sokusebenza okuvamile kwe-transformer, kukhona insimu kagesi phakathi kwama-windings aphilayo kanye ne-tank, futhi insimbi yensimbi nezinye izingxenye zensimbi zikule nsimu kagesi. Ngenxa yokusatshalaliswa okungalingani kwe-capacitance namandla ehlukene ensimu, uma ipayipi lensimbi nepayipi lensimbi engagqwali lomgogodla wensimbi lingakwazi ukumiswa, ukushaja nokukhipha kuzokwenzeka, okuzobhubhisa amandla okufakwa kwe-insulation namafutha, ngakho-ke umgogodla wensimbi kufanele ube nephuzu elingasekelwa.

I-iron core yakhiwe ngamashidi ensimbi ye-silicon namapayipi ensimbi namapayipi ensimbi engagqwali. Ukuze kuncishiswe ama-eddy currents, kunokumelana okuthile kokufakwa phakathi kwamashidi (ngokuvamile ama-ohm ambalwa kuya emashumini ambalwa ama-ohm). Kuthathwa njengendlela, ngakho-ke iphuzu elilodwa kuphela lokugxila kumgogodla wensimbi elingabamba amandla ayo yonke inqwaba yezingqimba zensimbi zibe namandla angaphansi.

Lapho inkaba yensimbi noma izingxenye zayo zensimbi zisekelwe emaphuzwini amabili noma ngaphezulu (amaphoyinti amaningi), iluphu evaliwe izokwakhiwa phakathi kwamaphoyinti aphansi, futhi i-flux kazibuthe yeketango lebhondi izofaka amandla e-electromotive futhi yakhe iluphu, okuholela Ekushiseni okweqile kwendawo ngisho nasekushiseni umgogodla wensimbi.

Iphuzu elilodwa kuphela le-transformer core lisekelwe, okuyisisekelo esivamile. Okusho ukuthi, ipayipi lensimbi lensimbi kufanele libekwe phansi, futhi kufanele lisekelwe endaweni eyodwa.

Ukuhluleka komgogodla wensimbi ngokuyinhloko kubangelwa yizizathu ezimbili, esinye isifunda esifushane esibangelwa inqubo yokwakhiwa engalungile, kanti enye i-multi-point grounding ebangelwa izinsiza ze-hose yensimbi engenasici kanye nezici zangaphandle.

Ukutholwa kwamaphutha aphansi wamaphuzu amaningi

Indlela yokwahlulela iphutha lesisekelo se-iron core ivame ukutholwa ezicini ezimbili:

(1) Yenza ukuhlaziywa kwe-gas chromatographic. Ekuhlaziyweni kwe-chromatographic, uma okuqukethwe kwe-methane ne-olefin kugesi kuphezulu, futhi okuqukethwe kwe-carbon monoxide ne-carbon dioxide gas kungashintshi kakhulu uma kuqhathaniswa nesikhathi esidlule, noma okuqukethwe kuvamile, kusho ukuthi umgogodla wensimbi. ishisa ngokweqile futhi umnyombo wensimbi ushisa ngokweqile. Ukushisa ngokweqile kungabangelwa ukubeka phansi ezindaweni eziningi.

Lapho igesi ye-acetylene ivela ekuhlaziyweni kwe-chromatographic, ibonise ukuthi i-iron core yayinezisekelo zamaphuzu amaningi.

(2) Linganisa ukuthi ingabe ikhona yini intambo ocingweni lwaphansi. Ungasebenzisa i-clamp meter ukukala ukuthi ikhona yini i-current at the ground lead of the grounding bushing ngaphandle kwe-transformer core. Lapho i-transformer core ngokuvamile isekelwe phansi, ayikho iluphu yamanje eyakhiwe. Ukugawula Okwamanje kulayini kuncane kakhulu, ezingeni le-milliamp (ngokuvamile ngaphansi kuka-0.3A). Uma kunamaphoyinti amaningi okumisa, kuba khona ukujika kwe-short-circuit ezungeze ukugeleza kozibuthe okuyinhloko kwe-iron core, futhi ukugeleza kwamanje okujikelezayo kugeleza, futhi inani lalo lincike endaweni yephutha kanye nendawo ehlobene yesisekelo esivamile. iphuzu, okungukuthi, inani le-flux kazibuthe elivalwe ekujikeni kwesiyingi esifushane. Ngokuvamile, ingafinyelela amashumi amaningana ama-ampere. Ngokukala ukuthi ingabe ikhona yini yamanje kumthofu ophansi, kunembe kakhulu ukunquma ukuthi ingabe kukhona iphutha lokubeka phansi lamaphuzu amaningi kumongo wensimbi.

Ukuxazulula izinkinga zamaphutha aphansi wamaphuzu amaningi

(1) Indlela yokuqeda isikhashana lapho i-transformer ingakwazi ukuvalwa:

①Kukhona intambo yangaphandle yaphansi. Uma iphutha lamanje lilikhulu, intambo yaphansi ingavulwa okwesikhashana ukuze isebenze. Kodwa-ke, ukuqapha kufanele kuqiniswe ukuze kuvinjwe inkaba yensimbi ekubonakaleni amandla antantayo ngemva kokunyamalala kwephuzu.

②Uma iphutha lokubeka phansi lamaphuzu amaningi liwuhlobo olungazinzile, ukumelana nentambo eshelelayo kungaxhunywa ochungechungeni ngentambo yaphansi esebenzayo ukuze kukhawulwe yamanje ibe ngaphansi kuka-1A. Ukukhethwa kokumelana nezintambo ezishelelayo ukuhlukanisa i-voltage elinganiswa lapho intambo evamile yaphansi yokusebenza ivulwa futhi ihlukaniswa yi-current on the ground wire.

③ Sebenzisa ukuhlaziywa kwechromatographic ukuze uqaphe izinga lokukhiqiza igesi endaweni yephutha.

④ Ngemva kokuthola iphuzu eliqondile lephutha ngokulinganisa, uma lingenakubhekwana nalo, ucezu oluvamile oluyisisekelo lwensimbi lungahanjiswa endaweni efanayo yephuzu lephutha ukuze kuncishiswe kakhulu amandla ajikelezayo.

(2) Qedela izinyathelo zokulungisa kabusha. Ngemuva kokuqapha kuthola ukuthi kukhona iphutha le-multi-point grounding ku-transformer, i-transformer engakwazi ukuvalwa kufanele ivalwe ngesikhathi, futhi iphutha le-multi-point grounding kufanele liqedwe ngokuphelele ngemva kokuphuma. Ukuze kuqedwe amaphutha anjalo, izinyathelo zokulondoloza ezihambisanayo kufanele zithathwe ngokusho kohlobo kanye nembangela ye-multi-point grounding. Kodwa-ke, kwezinye izimo, iphuzu lephutha alikwazi ukutholakala ngemuva kokumiswa kokuphela kukagesi. Ukuze uthole indawo okugxilwe kuyo ngokuqondile, izindlela ezilandelayo zingasetshenziswa esizeni .

① indlela ye-DC. Vula ucezu oluxhumayo lwepayipi lensimbi eliwumgogodla wensimbi kanye nesibambiso, bese udlulisela i-6V DC kumashidi ensimbi ye-silicon nhlangothi zombili zejoka, bese usebenzisa i-voltmeter ye-DC ukukala amandla kagesi phakathi kwawo wonke amazinga amashidi ensimbi ye-silicon. esikhundleni salokho. Uma i-voltage ilingana no-zero noma Uma inkomba yemitha ihlehliswa, ingabhekwa njengendawo yokubeka iphutha.

② indlela yokuxhumana. Xhuma i-low-voltage winding ye-transformer ku-voltage ye-AC engu-220~380V. Ngalesi sikhathi, kukhona ukugeleza kazibuthe epayipini lensimbi kanye nepayipi lensimbi engagqwali kumongo wensimbi. Uma kukhona amaphutha amaningi aphansi, sebenzisa i-milliammeter ukuze ulinganise amandla amanje (umgogodla wensimbi nama-clamps). Isiqephu sokuxhuma kufanele sivulwe). Sebenzisa i-milliammeter ukukala iphoyinti ngephoyinti eduze kwejoka lensimbi kuwo wonke amazinga. Uma i-current ku-milliampere inguziro, iphoyinti lephutha.
