Isizathu sokuthi kungani i-iron core idinga ukugaywa kancane uma ijwayelekile

Ngesikhathi sokusebenza okuvamile kwe-transformer, kuba nensimu kagesi phakathi kwama-windings aphilayo nethangi, kanti i-iron core nezinye izingxenye zensimbi zikule nsimu kagesi. Ngenxa yokusatshalaliswa okungalingani kwamandla kanye namandla ahlukene ensimu, uma i-iron hose kanye ne-stainless steel hose ye-iron core ingenakukwazi ukumisa, kuzokwenzeka ukushaja nokukhipha, okuzobhubhisa amandla okufaka okuvikela okuvikela okuvikela okuvikela okuvikelayo kanye namafutha, ngakho-ke i-iron core kumele ibe nephuzu elingamisa.

Ingaphakathi lensimbi lakhiwe ngamashidi ensimbi e-silicon namapayipi ensimbi kanye namapayipi ensimbi engagqwali. Ukuze kuncishiswe imisinga ye-eddy, kukhona ukumelana okuthile kokushisa phakathi kwamashidi (ngokuvamile ama-ohms ambalwa kuya kwamashumi amaningana ama-ohms). Kubhekwa njengendlela, ngakho-ke iphuzu elilodwa kuphela lokufaka inhlabathi engaphakathi kwensimbi elingabamba amandla enqwaba yonke yama-lamination engaphakathi kwensimbi emandleni omhlaba.

Uma i-iron core noma izingxenye zayo zensimbi zisekelwe ezindaweni ezimbili noma ngaphezulu (ama-multi-point), kuzokwakhiwa i-loop evaliwe phakathi kwama-grounding points, futhi i-magnetic flux ye-bond chain izobangela amandla e-electromotive futhi yakhe i-loop, okuholela ekushiseni ngokweqile kwendawo ngisho nokushisa i-iron core.

Iphuzu elilodwa kuphela le-transformer core elisekelwe, okuwukusekelwe okuvamile. Okusho ukuthi, ipayipi lensimbi le-iron core kumele lisekelwe, futhi kumele lisekelwe endaweni eyodwa.

Ukwehluleka kwe-iron core kubangelwa kakhulu yizizathu ezimbili, esinye yi-short circuit ebangelwa inqubo yokwakha embi, kanti esinye yi-multi-point grounding ebangelwa izesekeli ze-hose yensimbi engagqwali kanye nezici zangaphandle.

Ukutholwa kwamaphutha omhlaba anamaphuzu amaningi

Indlela yokwahlulela iphutha lokusekela i-iron core elinamaphoyinti amaningi ivame ukutholwa ezicini ezimbili:

(1) Yenza ukuhlaziywa kwe-gas chromatographic. Ekuhlaziyweni kwe-chromatographic, uma okuqukethwe kwezingxenye ze-methane ne-olefin kugesi kuphezulu, futhi okuqukethwe kwe-carbon monoxide ne-carbon dioxide gas kungashintshi kakhulu uma kuqhathaniswa nesikhathi esidlule, noma okuqukethwe kujwayelekile, kusho ukuthi i-iron core ishisiwe kakhulu kanti i-iron core ishisiwe kakhulu. Ukushisa ngokweqile kungabangelwa ukucwiliswa ezindaweni eziningi.

Lapho kuvela igesi ye-acetylene ekuhlaziyweni kwe-chromatographic, kwabonisa ukuthi umongo wensimbi wawune-intermittent multi-point grounding.

(2) Kala ukuthi kukhona yini ugesi entanjeni yokumisa. Ungasebenzisa imitha yokubamba ukuze ulinganise ukuthi kukhona yini ugesi entanjeni yokumisa ye-grounding bushing ngaphandle kwe-transformer core. Uma i-transformer core ivame ukuba semhlabeni, akukho luphu lwamanje olukhona. Ukumisa Ugesi Ugesi olayini mncane kakhulu, ezingeni le-milliamp (ngokuvamile ungaphansi kuka-0.3A). Uma kunamaphuzu amaningi okumisa, kuba nokujika kwe-short-circuit kuzungeze i-magnetic flux eyinhloko ye-iron core, kanye nogesi ojikelezayo ugeleza ekujikeni, futhi inani lawo lincike endaweni yephutha kanye nendawo ehlobene ye-grounding point evamile, okungukuthi, inani le-magnetic flux elivalelwe ekujikeni kwe-short-circuit. Ngokuvamile, lingafinyelela amashumi amaningana ama-ampere. Ngokukala ukuthi kukhona yini ugesi entanjeni yokumisa, kunembile kakhulu ukunquma ukuthi kukhona yini iphutha le-grounding elinamaphoyinti amaningi entanjeni yensimbi.

Ukuxazulula izinkinga zamaphutha omhlaba amaningi

(1) Indlela yokususa okwesikhashana lapho i-transformer ingenakucinywa:

①Kukhona ucingo olungaphandle lomhlabathi. Uma ugesi wephutha mkhulu, ucingo oluphansi lungavulwa okwesikhashana ukuze lusebenze. Kodwa-ke, ukuqapha kumele kuqiniswe ukuze kuvinjelwe ukuthi insimbi ingabonakali ingantanta ngemva kokuba iphuzu lephutha selinyamalele.

②Uma iphutha lokumisa phansi elinamaphoyinti amaningi lingelohlobo olungazinzile, ukumelana kwentambo eshelelayo kungaxhunywa ngokulandelana nentambo yomhlabathi osebenzayo ukuze kuncishiswe ugesi ube ngaphansi kuka-1A. Ukukhetha ukumelana kwentambo eshelelayo ukuhlukanisa i-voltage elinganisiwe lapho intambo yomhlabathi osebenzayo evamile ivulwa futhi ihlukaniswe ugesi entanjeni yomhlabathi.

③ Sebenzisa ukuhlaziywa kwe-chromatographic ukuqapha izinga lokukhiqizwa kwegesi endaweni lapho iphutha likhona khona.

④ Ngemva kokuthola iphuzu eliqondile lephutha ngokulinganisa, uma lingenakuxazululwa, ingxenye evamile yokusebenza yesisekelo sensimbi ingathuthelwa endaweni efanayo yephuzu lephutha ukuze kuncishiswe kakhulu umjikelezo wamanzi ojikelezayo.

(2) Izinyathelo zokulungisa eziphelele. Ngemva kokuqapha kutholakele ukuthi kukhona iphutha lokumisa isisekelo elinamaphoyinti amaningi ku-transformer, i-transformer engavalwa kufanele ivalwe ngesikhathi, futhi iphutha lokumisa isisekelo elinamaphoyinti amaningi kufanele lisuswe ngokuphelele ngemva kokuphuma. Ukuze kuqedwe amaphutha anjalo, kufanele kuthathwe izinyathelo zokulungisa ezifanele ngokuya ngohlobo kanye nembangela yokumisa isisekelo elinamaphoyinti amaningi. Kodwa-ke, kwezinye izimo, iphuzu lokumisa alitholakali ngemva kokumiswa kukagesi. Ukuze kutholakale iphuzu lokumisa isisekelo ngqo, izindlela ezilandelayo zingasetshenziswa endaweni.

① Indlela ye-DC. Vula ingxenye yokuxhuma yepayipi lensimbi eliyinhloko yensimbi kanye ne-clamp, bese udlulisela i-6V DC kumashidi ensimbi e-silicon ezinhlangothini zombili ze-joke, bese usebenzisa i-DC voltmeter ukukala i-voltage phakathi kwawo wonke amazinga amashidi ensimbi e-silicon ngokulandelana. Uma i-voltage ilingana no-zero noma Uma inkomba yemitha ibuyiselwa emuva, ingabhekwa njengendawo yokumisa iphutha.

② Indlela yokuxhumana. Xhuma ukugoqa okuphansi kwe-transformer ku-voltage ye-AC engu-220 ~ 380V. Ngalesi sikhathi, kukhona ukugeleza kukazibuthe ku-hose yensimbi kanye ne-hose yensimbi engagqwali engxenyeni yensimbi. Uma kunezinkinga eziningi zomhlabathi, sebenzisa i-milliameter ukukala ugesi (ingxenye yensimbi kanye nama-clamp). Ingxenye exhumanisayo kufanele ivulwe). Sebenzisa i-milliameter ukukala iphuzu ngephuzu eduze kwe-iron jock kuzo zonke izigaba. Uma ugesi ku-milliampere ungo-zero, kuba yindawo yephutha.
