I-fuse yamanje ekhawula amandla kagesi aphezulu iyasebenza ku-AC 50Hz yasendlini, ama-voltage akalwe angu-3.6KV, 7.2KV, 12KV, 24KV, 40.5KV, ama-currents alinganiselwe angu-0.5 no-2, 3, 5, 7.5, 10A, futhi ayasebenza ekuvikeleni amasistimu ukugcwala ngokweqile kanye namaphutha wesekethe emfushane yama-voltage angu-35KV angaphandle kanye nemigqa yamandla.Ingasetshenziswa kanye namanye amadivaysi okushintsha, njengokushintshwa komthwalo kanye nezixhumi zangempela, njengento evikelayo yesifunda esifushane kanye nokugcwala ngokweqile kwama-transformer amandla namanye amadivaysi ayisipele, futhi iwumkhiqizo osekelayo odingekayo wamafreyimu okushintsha amandla kagesi aphezulu, indandatho. amafreyimu enethiwekhi, kanye neziteshi ezingaphansi ezakhiwe ngaphambilini eziphakeme/eziphansi.
I-fuse yamanje ekhawulela amandla kagesi aphezulu inomkhawulo wamanje kanye nokushesha.Inani eliphakeme le-fault current livame ukuvela igagasi elinguhhafu.Uma umzimba webhuloho unqanyulwa, wonke amandla omjikelezo omfushane azodluliselwa ku-fuse yamanje yokunciphisa amandla aphezulu.I-current short circuit yangaphakathi ye-fuse izohwamuka, yehle, ikhiqize i-arc phakathi kwezikhala futhi icime i-arc esikhathini esizayo nalapho iphakama, ikhawule futhi inqamule ngamandla i-short circuit current (t ＜ 2ms), ukuze i-current ingakwazi. finyelela inani eliphakeme elilindelekile lesifunda esifushane samanje.Lapho i-current-circuit current ikhuphukela ku-Ip, i-fuse izohlanganisa futhi inqamule yamanje.I-Ip yamanje enqanyuliwe ilinganiselwa ku-15% kuphela yenani eliphakeme lamanje elilindelekile, linciphisa kakhulu umthelela wephutha lamanje kumandla we-electrodynamic kanye nomthelela oshisayo wokuphehla amandla kanye nezisetshenziswa zokuguqula.Amandla kagesi we-arc akhiqizwa i-fuse yamanje ekhawulela i-high-voltage yamanje angakhawulwa ukumelana okungeyona i-linear, okungabambisana nokumelana nebhuloho ukuxazulula inkinga yomthamo onganele we-fuse yamanje yokukhawulela yamandla aphezulu futhi kuthuthukiswe ububanzi bokusebenza balo lonke. idivayisi.
I-fuse yenziwe ngeshubhu elincibilikayo, i-porcelain bushing (i-silicone rubber insulation sheath), i-flange yokubopha, isivikelo seposi esiphambanayo kanye netheminali.Lungisa amakepisi wetheminali bese uncibilikisa amapayipi kuzo zombili iziphetho ku-porcelain bushing ngokucindezela, bese ulungisa i-porcelain bushing ku-insulator yenduku nge-flange eqinile.
Ipayipi elincibilikayo lamukela ukunakekelwa nge-silicon oxide ephezulu njengendawo yokucima i-arc, futhi ucingo lwensimbi olunobubanzi obuncane lusetshenziswa njengefuse.Lapho i-overload yamanje noma i-short circuit current idlula ku-melt tube, i-fuse izoncibilika ngokushesha.I-arc yenzeka emifantwini eminingana emincane emincane.Umhwamuko wensimbi ku-arc ungena esihlabathini se-quartz, uhlukaniswe ngokuqinile, futhi ucisha ngokushesha i-arc.Ngakho-ke, i-fuse inokusebenza okuhle kanye namandla amakhulu okuphuka.

I-fuse yamanje ekhawula yangaphandle ene-voltage ephezulu

Izici zomkhiqizo

1. Umthamo omkhulu wokuphuka.Ngokuvamile, amandla okuphuka kwesekethe emfishane (inani elisebenzayo elilindelekile) lamafuse alawula amandla kagesi aphezulu asekhaya angu-50kA, kanti amandla okuphuka kwesekethe efushane kweminye imikhiqizo engenisiwe afinyelela ku-63kA.
2. Umthamo wamanje wokukhawulela, ngokuvamile amafuse asekhaya anamandla amakhulu anamandla, njengamafuse angu-100A, inani eliphakeme lamanje elinqamuliwe licishe libe ngu-18kA lapho inani elisebenzayo le-short-circuit current elindelekile lingu-50kA, kuyilapho endaweni ethile. I-fuse engu-100A engenisiwe, ku- Lapho inani elisebenzayo lamanje lesekethe emfishane elilindelekile lingu-63kA, inani eliphakeme lamanje elisikiwe lingu-18kA kuphela.
3. Kukhona ubuncane be-breaking current.Kumafuse anomkhawulo wamanje wokuvikela i-transformer, isilinganiso esincane sokuphuka ngokuvamile siphindaphinda izikhathi ezi-3 kuya kwezi-5 kunamanje olinganiselwe we-fuse.Lapho ukhetha, kufanele kuqinisekiswe ukuthi ubuncane bayo be-fusing current abukho bukhulu kunobuncane be-short-circuit current yesekethe evikelekile.
4. Ukulahlekelwa kwamandla kuncane, okuqinisekisa ukuthi umkhiqizo unokukhuphuka okuphansi kwezinga lokushisa.Lesi sici sizuzisa kakhulu uma i-fuse isetshenziswa emshinini wokufaka ovalekile ngokugcwele.I-low arc voltage: Ngesikhathi senqubo yokuphuka, i-arc voltage iphansi, futhi uma isetshenziswa ohlelweni olune-voltage ephansi kune-voltage elinganiselwe, i-arc voltage izophinde yehliswe, ukuze i-fuse engu-12KV isetshenziswe I-12KV noma i-7.2KV uhlelo ngaphandle kokulimaza ingozi yokufakwa kwesistimu.
5. Iphutha lejika lesici lincane, futhi iphutha lejika lesici sesikhathi samanje lingaphansi kuka-± 10%, okuqinisekisa ukwethembeka komkhiqizo.Ngaphezu kwalokho, zonke zihambisana nezinga le-International Electrotechnical Commission (IEC).Uhlobo lwebhasi lungafakwa ngokuqondile kubha yebhasi ngezikulufo, ezinezinzuzo zevolumu encane yokufaka nokuxhumana okuthembekile;kuyilapho uhlobo lwe-plug-in kulula ukushintshwa futhi lungasetshenziswa ngogesi.
