I-S11-MD Underground Transformer
Uguquko olungaphansi komhlaba luwuhlobo lwe-transformer yokusabalalisa noma i-transformer ehlanganisiwe engafakwa ku-silo; iyisikhungo sokusabalalisa esihlangene esihlangene lapho i-transformer, i-high voltage load switch kanye ne-fuse yokuvikela njll., ingafakwa ethangini likawoyela.Izinga Lereferensi: JB/T 10544-2006,
I-transformer engaphansi komhlaba ingasetshenziselwa kokubili uhlelo lokuphakela amandla kagesi aphezulu olunebanga elide, izici zomthwalo omncane kumaphrojekthi afana nomgwaqo, ibhuloho, amahubhu, njll., futhi isetshenziswe njengama-transformer ahlanganisiwe kumaphrojekthi lapho izintambo ezihamba phezulu zifakwe izintambo ngaphansi komhlaba njenge kanjalo nokuphakelwa kukagesi ezindaweni zokuhlala.
Isetshenziswa kabanzi ekunikezeni amandla ngokwethembeka okuphezulu futhi ayinawo umthelela endaweni ezungezile.Amasethi amathathu kagesi angaphansi komhlaba angu-50Hz kanye nenethiwekhi yokusabalalisa enesigaba sikagesi esingu-10kV nangaphansi angasetshenziselwa ukusatshalaliswa kwamandla kagesi kanye nokukhanyisa ezindaweni zemigwaqo emikhulu yasemadolobheni, izikhumulo zezindiza, amabhuloho amakhulu, imigudu, iGreenland enkulu noma amapaki, njll.
Isiteshi esingaphansi sohlobo lwebhokisi lesiguquli esingaphansi komhlaba esakhelwe ngaphambili siyisethi ephelele yezinto zokusebenza ehlanganiswe nekhabhinethi yokushintsha isitayela sebhokisi elikhanyayo nesisele esenziwe ngaphambili, esifakwe ngaphambili futhi esiphumelele ukuhlolwa efekthri.Umkhiqizo wakhiwe izingxenye ezimbili zemishini ngaphansi nangaphezulu komhlaba.Ingxenye engezansi komhlaba ihlanganisa isisele esenziwe ngaphambili (noma ukubunjwa kukakhonkolo esizeni) kanye nesiguquli esingaphansi komhlaba.Ingxenye engaphezulu komhlaba ihlanganisa isitayela sebhokisi elikhanyayo (noma lendabuko) indawo ye-swith yangaphandle kanye nemigudu yokukhipha umoya.Umkhiqizo ulungele izinhlobonhlobo eziphezulu zezinhlelo zokusabalalisa amandla asemadolobheni, ikakhulukazi amaphrojekthi asizayo wamandla okwakhiwa komphakathi afana nokukhanda kabusha ikhebula elingaphansi komhlaba.
I-Landscape Underground Box-type Transformer ingumkhiqizo owenziwe futhi wakhiqizwa ngokuzimela yinkampani yethu.Kuyi-transformer yenoveli eyakhiwe nge-transformer ehlanganisiwe engaphansi komhlaba, ikhabethe lamandla kagesi aphansi kakhulu, ikesi lokuvikela lesitayela sebhokisi elikhanyayo kanye nesiguquli esingaphansi komhlaba esenziwe ngaphambili.Lesi siguquli singenziwa ngendlela efanele ngokuvumelana nezici zemvelo ukuze kuzuzwe ukuhlangana okuhle kwendawo ezungezile futhi kuhlobise imvelo.
♦ Ukuhlala kancane komhlaba ngaphandle kokuthatha indawo engaphezulu, umphumela omuhle wezwe kanye nokufaka kalula.
♦ Ukubona indlela yokufaka eduze nendawo yokulayisha kanye nokuphakelwa kwamandla kagesi, konga isibalo samakhebuli anamandla aphansi kanye nokutshalwa kwezimali, kuncishiswe ukulahleka kwezintambo ukuze kuqinisekiswe ukusebenza komnotho.
♦ Ibanga lokuvikela i-IP68, elimelene nokuqhuma, elikwazi ukucwiliswa ngokuphelele emanzini isikhathi esithile futhi lithuthukise ngempumelelo ukwethembeka kwezinhlelo zokuphakelwa kukagesi.
♦ Ithangi likawoyela lisebenzisa insulating egcwele, evalwe ngokugcwele futhi eshiselwe ngokuphelele, ebekezelelwa ku-70kPa ngaphandle kokuvuza noma ukuguquguquka ukuze kuthuthukiswe ukusebenza kahle kwemishini kwethangi likawoyela;asikho isidingo sebanga lokuhlukanisa futhi sikwazi ukuqinisekisa ukuphepha kwabasebenzi;isebenzisa irediyetha eyingqayizivele ukuze kuqinisekiswe amandla emishini namandla okupholisa erediyetha.
♦ Ukuxhumeka kwekhebula eliphezulu/eliphansi kungasebenzisa lezi zindlela ezilandelayo:
1.Faka izigaba ezintathu ngesikhathi esisodwa kusixhumi sekhebula sezigaba ezintathu ngaphakathi kwe-transformer nakumajoyinti ekhebula emodi ekhethekile (esebenza ku-transformer engaphansi komhlaba enezigaba ezintathu enesigaba samandla kagesi njengo-10kV nangaphansi, umthamo ongu-400kVA nangaphansi)
2.Sebenzisa isixhumi sekhebula esinesigaba esisodwa kanye ne-terminal block exhunywayo yohlobo lwendololwane (isebenza ku-transformer engaphansi kwezigaba ezintathu enesigaba samandla kagesi njengo-10kV nangaphansi, umthamo ongu-1600kVA nangaphansi).
3.Uhlobo loketshezi lwe-patent insulating lugcwaliswa ngaphakathi kwesixhumi ukuze kuhlukaniswe uketshezi lwe-insulating ku-transformer futhi kuqinisekiswe ukusebenza okuvamile uma amanzi ephuma ngenxa ye-capillary phenomenon.
♦ Ingakwazi ukuhlonyiswa ngeswishi yokulayisha ecwiliswe uwoyela ukuze ivuleke futhi ivale ukusebenza lapho ilayishwa futhi ibone inethiwekhi yendandatho namandla kagesi agcinayo, okulula ukushintsha phakathi kwalezi zindlela ezimbili ezithuthukisa ukuthembeka kokuphakelwa kukagesi.
♦ Ikhabhinethi yokushintsha isitayela sebhokisi elikhanyayo ye-transformer engaphansi komhlaba eyakhiwe kuqala kulula ukuyifaka futhi ihehe ababukeli ngenxa yangaphandle yayo ethuthukisiwe, ngaphezu kwalokho, isikhangiso sendiza yebhokisi lokukhanya singaletha izinzuzo ezinhle zezomnotho.
♦ Ikesi le-transformer eligqitshiwe lisebenzisa umoya wemvelo;idizayini edidiyelwe yokukhuphuka kwezinga lokushisa yenziwa ngokucabangela i-transformer, silo kanye nebhokisi elikhanyayo.Inani lokukhuphuka kwezinga lokushisa le-transformer egijima kumthwalo olinganiselwe kusilo lihlangabezana nezimfuneko ze-GB 1094.2 evamile.
♦ Isistimu yokukhipha amanzi ezenzakalelayo ingafakelwa isisele, ezimeni ezikhethekile zezikhukhula, njll., izoqalisa ngokuzenzakalelayo imishini yokukhipha amanzi.
