1. Izesekeli zekhebula ezishisa ngokushisa
Izesekeli zekhebula ezishisa ngokushisa, ezaziwa kakhulu ngamakhanda ekhebula eshisayo, yizona izesekeli ezivame kakhulu ekuthuthweni kwamandla. Zijwayele ukusetshenziselwa kumatheminali wezintambo ezixhumene namandla aphezulu noma aphansi noma izintambo ezifakwe uwoyela. Uma kuqhathaniswa nezesekeli zendabuko, zincane ngosayizi, zikhanya ngesisindo, futhi Kuphephile, kuthembekile futhi kulula ukufakwa. Isetshenziswa kakhulu ekuxhumaneni okuphakathi naphakathi kwamathebula wezintambo ezixhumene noma izintambo ezifakwe uwoyela ezinamazinga we-35KV nangaphansi. Umkhiqizo uhambisana nezinga le-GB11033, ibanga lokushisa lokusetshenziswa lesikhathi eside ngu -55 ℃ ～ 125 ℃, impilo yokuguga yinde eminyakeni engama-20, izinga lokuncipha kusabalalayo lingu- ≥50%, izinga lokuncipha le-longitudinal lingu- <5% , futhi izinga lokushisa lokuncipha ngu-110 ℃ ～ 140 ℃.
2. Izesekeli zekhebula ezisongelwe
Izixhumi zekhebuli ezigoqiwe zivame ukusetshenziselwa izixhumi zekhebula ezinamandla amancane. Izixhumi ezigoqiwe zekhebula zilinyazwa nge-tape evikela ipulasitiki. Ukungavikeleki kwamanzi, ukuqina kwayo, nobuhle bayo abufani namakhanda ekhebula ancipha ekushiseni. Ububanzi besicelo bunqunyelwe ezintanjeni ezinobubanzi obuyisisekelo obulodwa obungaphansi noma obulingana no-70mm2. Ingabekwa kuphela obala, ingangcwatshwa phansi, futhi inokusebenza okuphephile. Ukuthinta izinto ezibukhali noma ukushaya ngamandla angaphandle kungalimaza ithephu yokuvikela isilonda futhi kubangele izingozi zokuvuza. Kepha kukhona inzuzo, okungukuthi, izindleko ziphansi futhi ukwakhiwa kulula.
3, izixhumi zekhebula ezibandayo ezibandayo
Izixhumi zekhebula ezincipha ngokubanda manje sezivame ukusetshenziswa ngamashubhu wokulawula ukucindezela okubandayo, ngamazinga kagesi asukela ku-10kV kuye ku-35kV. Ngamakhanda wokugcina wekhebula anciphise ukubanda, ikilasi elingu-1kV lisebenzisa amashubhu okuvikela ukushisa okubandayo ekuqiniseni okuqinisiwe, kanti ikilasi le-10kV lisebenzisa amalunga ancipha abandayo anezingqimba ezivikela ngaphakathi nangaphandle. Okokusebenza okuncishiselwa ikhebula okusetshenziswayo kusebenzisa ukuqina okuhle kakhulu kokumelana nezinyembezi nokuqina okuphezulu kwe-silicone iraba, futhi isebenzisa izinto zokuxhasa zepulasitiki eziyizigaxa ukukhulisa izesekeli zokuqala kubukhulu bangaphandle obudingekayo ngenqubo. Ngemuva kokufakwa, izinto zokuxhasa zixhunywe ngokuqhubekayo. Yikhiphe, futhi izesekeli zihlanganiswe ngokuqinile kukhebuli ngokuqina kwenjoloba. Izimo zokusetshenziswa: -50 ～ 200.
Amakhanda we-cable-shrinkable cable terminal anezinzuzo zosayizi omncane, ukusebenza okulula nokusheshayo, awekho amathuluzi akhethekile, ububanzi besicelo esibanzi nemininingwane embalwa yomkhiqizo. Uma kuqhathaniswa nezesekeli zekhebula ezincishiswa ukushisa, ayidingi ukufudunyezwa ngomlilo, futhi ngemuva kokufakwa, ngeke isuswe noma igobeke njengezinsimbi zekhebula ezincishiswa ukushisa. Abukho ubungozi bokunqanyulwa phakathi kwezendlalelo zangaphakathi zezesekeli (ngoba izesekeli zekhebula ezincipha ngokubanda zenziwe ukumelana okuphezulu kwezinyembezi, ukuqina okuphezulu kwe-silicone irabha amandla wokuncipha okunwebeka).
4, uhlobo izixhumi zekhebula
Ukukubeka nje, izixhumi zekhebula lohlobo lokusakaza ukusebenzisa isikhunta ukulungisa ikhanda lekhebula, bese uthela i-epoxy resin kuyo, bese ususa isikhunta ngemuva kokumisa. Kuyinkinga kakhulu futhi akukwazi ukuthululelwa kulwandle ukugwema umswakama nokunciphisa ukufakwa kwekhanda lekhebula.
5, izesekeli zekhebula ezenziwe ngaphambilini
Kuyinto isesekeli esenziwe ngokujova i-silicon iraba ezingxenyeni ezahlukahlukene, ivuthisa futhi ibumbe ngasikhathi sinye, kusale kuphela i-interface yokuxhumana, nokufaka izintambo ngesikhathi sokwakhiwa kwesiza. Inqubo yokwakha inciphisa izinto ezingalindelekile ezingezinhle emvelweni ziye ezingeni eliphansi ngokwanele. Ngakho-ke, isesekeli sinenani elikhulu lokusetshenziswa okungenzeka futhi siyisiqondiso sokuthuthuka sezinsimbi ezixhunywe enqamulelayo. Kodwa-ke, ubuchwepheshe bokukhiqiza bunzima futhi buhilela imikhakha eminingi nezimboni.
