Iyini ikhebulainkomba yephutha?
Isikhombisi sephutha uhlobo lwemishini yokungenisa kagesi engabonisa ukuthi kukhona ugesi wesifunda esifushane ngophawu lwephutha (ikhadi elibomvu).
Faka inkomba yephutha eceleni komugqa wokusabalalisa. Uma umugqa wehluleka futhi ugesi we-short-circuit ugeleza, inkomba yephutha izosebenza bese kuvela ikhadi elibomvu.
Bese uzulazula eceleni komugqa, uhlangothi lokunikezwa kwamandla oluya ephutheni ngaphambi kwekhadi elibomvu lesibonakaliso sephutha, isibonakaliso sephutha ngemuva kwephoyinti lephutha asibonakali ekhadini elibomvu, ungahlulela ukuthi iphuzu lephutha liphakathi kwephoyinti lokugcina lekhadi elibomvu nephoyinti lokuqala elingelona elibomvu.
Isikhombisi sephuthangokuvamile kufaka phakathi ukutholwa kwamanje kanye ne-voltage, ukuhlonza amaphutha, umshayeli wesibonakaliso sephutha, inkomba yesimo sephutha kanye nokukhishwa kwesignali kanye nokulawula ukusetha kabusha ukubambezeleka okuzenzakalelayo.
Isikhombisi sephuthangokuvamile ifakwe emgqeni ophezulu, ikhebula elingaphezulu noma ikhebula elifihliwe, ibhasi lekhabhinethi elishintshiwe, ngakho-ke ithola i-voltage ngokuthola i-gradient yamandla kagesi yendawo, ngokusebenzisa i-electromagnetic induction ukuthola umugqa wamanje.
Incazelo Yomkhiqizo
Isikhombisi se-grounding short circuit two-in-one sinamagatsha amaningi kanye namaphutha avamile. Ukuthola amaphutha emigqa kuyindaba ebuhlungu kubasebenzi bokulungisa imigqa kagesi. Ukuthola iphutha lomhlabathi ngezinye izikhathi kuthatha isigamu sosuku, kanti abanye balithola ebusuku ekuseni, kanti abanye balithola e-Inner Mongolia. Ukuthola izinsuku ezimbalwa. Ngakho-ke, ukufakwa kwesikhombisi sephutha kungathuthukisa kakhulu ukuthembeka kokunikezwa kwamandla kagesi, kunciphise amandla abasebenzi, futhi kufinyeze isikhathi sokuphela kwamandla kagesi.
Izici:
1. Nikeza usizo kanye nokulula kokuxazulula izinkinga ngesikhathi sokwehluleka komugqa.
2. Ngokuya ngobukhulu bomthwalo womugqa kanye nokusatshalaliswa komkhuba womugqa, kunqunywa indawo efanele yokufaka inkomba yephutha.
3. Uma umugqa usebenza ngokujwayelekile, inkomba isesimweni sokusetha kabusha ngaphandle kwenkomba.
4. Uma kwenzeka iphutha le-short circuit noma i-ground fault emugqeni, i-indicator iphendula ngokuzenzakalelayo isitsha se-indicator emini bese iba yisimo sokubonisa i-alamu ebomvu; abasebenzi bokulungisa iphutha le-line bangathola indawo yephutha ngokwesimo se-indicator.
5. Isikhathi esizenzakalelayo sasembonini sokusetha kabusha umkhiqizo singamahora ayi-12 (isikhathi sokusetha kabusha singalungiswa ngokuya ngezidingo zamakhasimende).
6. Lo mkhiqizo unikeza usizo olunamandla ekuxazululeni inkinga yamaphutha emigqa futhi kulula ukuthola indawo yamaphutha.
7. Nciphisa isikhathi sokuphela kukagesi bese wandisa ukunikezwa kukagesi.
8. Asikho isidingo sokuvala ukufakwa komkhiqizo, amathuluzi okufaka ochwepheshe anikezwa mahhala, futhi ukuqaqa kulula.
Isimiso Somkhiqizo
Ukutholwa kwesekethe esifushane: Isekethe yokuthola inoshintsho oluzumayo kumandla kagesi lapho kwenzeka iphutha lesekethe esifushane, futhi inani loshintsho oluzumayo likhulu kunenani elithile (elingasethwa ngokuya ngesethingi yokuvikela i-relay) phakathi nesikhathi esithile sokukhubeka nokuphela kukagesi.
Ukutholwa kokumisa umhlabathi kuthola izinguquko ze-voltage, ama-capacitor currents kanye nezimo zesigaba lapho kumisa umhlabathi, kuthola izinguquko ze-harmonic, futhi kunquma ngokuphelele ukuthi ukumisa umhlabathi kuyenzeka yini.
15kV200Aisivalo sokuvikela esivikelwe
Incazelo Yomkhiqizo
I-15kV 200Aisivalo sokuvikela esivikelweiyingxenye yokwengeza ye-bushing ephilayo. Ihlinzeka ngesembozo sokuvikela i-bushing ephilayo kanye nesembozo esingangeni uthuli futhi esingangeni umswakama samalunga angakashajwa.
I-200Aisivalo sokuvikela esivikelweingafakwa ezihlahleni ezingama-200A, ezihlahleni zamabhasi kanye nemishini yokulenga odongeni. Uma i-busbar kanye nezihlanganisi zekhebula zigcinelwe izindawo zokubeka ezinye, kumele zivalwe ngezivalo zokuvikela ezingama-200A.
isakhiwo somkhiqizo
Isendlalelo sokufaka umswakama: Ifomula eyingqayizivele kanye nobuchwepheshe bokuxuba buqinisekisa ikhwalithi ephezulu yerabha yethu yokufaka umswakama ye-EPDM esele yenziwe.
Isendlalelo sangaphandle esidonsa kancane: irabha eqhubayo ye-EPDM elungiselelwe kusengaphambili ihlangabezana nezindinganiso ze-IEEE592.
Iso elisekelayo: iso elisekelayo elihlanganiswe nesendlalelo sangaphandle esihambisayo kancane, esisetshenziselwa ukusekela umkhiqizo.
Indandatho yokusebenza: Indandatho yokusebenza yensimbi engagqwali ebunjiwe ngengxenye eyodwa enezindawo zokubopha i-spring clamp.
Ibha yebhasiuhlelo
Incazelo Yomkhiqizo
Izixhumi zesitayela saseYurophu ezingama-630A eziyisiphambano nezimise okwe-T zisetshenziswa kakhulu ekuxhumeni okuvikelwe ngokuphelele nokuvalwe ngokuphelele kwe-switch bus yekhabhinethi yenethiwekhi yendandatho, okuhambisana ne-bushing ejwayelekile yekhabhinethi yenkinobho, futhi kufanelekile emabhokisini amagatsha anezinkinobho. Ikhabhinethi yenkinobho ivalwe ngokuphelele futhi ivalwe ngokuphelele, igwema ngokuphelele amaphutha abulalayo abangelwa ukuvezwa kwamandla aphezulu esimweni sezulu esibi. Umkhiqizo owenziwe ngama-busbars kanye nama-D kanye nama-cross joints ubizwa ngokuthi uhlelo lwe-busbar, oluyisimiso esithandwayo sekhabhinethi yenethiwekhi yendandatho. Izinzuzo eziyinhloko yilezi: izindleko eziphansi kanye nokusebenza okuthembekile kakhudlwana. Ubude bebha yebhasi bungenziwa ngokwezifiso ngokwezidingo zekhasimende. Ukuxhumeka kwe-D kanye ne-cross kungenziwa kube imikhiqizo evikelwe noma engavikelwe ngokwezidingo zamakhasimende.
