Indlela Yokufaka Isixhumi Sesikhungo Sekhebula

Ukuxhumana phakathi kwengxenye eyodwa yekhebula nenye ingxenye yekhebula kubizwa ngokuthi isixhumi sekhebula. Kunomphumela wokuxhuma ama-conductor, ukuvikela, ukuvala kanye nokugcina.

(1) Isicelo esiyisisekelo sesixhumi esiphakathi: Isixhumi esiphakathi kanye nekhanda lesiphetho sekhebula lekhebula kuyizixhumanisi ezibuthakathaka ekusebenzeni okuphephile kwekhebula, ngakho-ke kufanele kuqashelwe ngokukhethekile izidingo zokukhetha nokwakha. Isakhiwo sesixhumi esiphakathi esingu-10kV nangaphansi sifana kakhulu. Njengesiphetho, sihlanganisa kakhulu izingxenye ezine: ukuhlanganiswa kwama-guides okuqandisa, ukuqinisa izinga lobukhulu, ukungangeni manzi nokuvala, kanye nokugcinwa kwemishini. Izidingo eziyisisekelo zesixhumi esiphakathi manje zihlukaniswe ngalezi ezilandelayo:

① Uxhumano oluhle kakhulu lwe-conductor. Kudingeka ukuthi kube noxhumano oluvelele phakathi kwe-core yekhebula noxhumano, ukuze ukumelana kokuthinta ekuxhumeni kube kuncane futhi kuzinzile.
②Ukufakwa komoya okuthembekile. Kuyadingeka ukuba nesakhiwo sokufaka umswakama esingahlangabezana nokusebenza okuphephile kwesikhathi eside komugqa wekhebula ngaphansi kwezimo ezahlukahlukene, futhi sibe nomkhawulo othile.
③Ukuvala okuhle kakhulu.
④ Ukugcinwa kahle kwemishini kungcono. Igobolondo lensimbi lejoyinti eliphakathi liyisihluthulelo sokugcina ukufudumala, kanye nomphumela wokugcinwa kahle kwemishini ejoyintini.

(2) Izinhlobo zamajoyinti aphakathi: Amajoyinti aphakathi ezintambo ezingu-10kV nangaphansi anohlobo lwe-cast iron integral, uhlobo lwe-steel plate sealing welding butt joint, uhlobo lwe-lead (ithusi) noma uhlobo lwe-aluminium alloy casing, ipulasitiki, i-epoxy resin casting nezinye izinhlobo. Njengamanje, ibhokisi lokuxhumana eliphakathi elenziwe nge-lead (ithusi) kanye ne-aluminium alloy lisetshenziswa kabanzi, futhi i-insulating glue ithululelwa ebhokisini, elinomphumela wokuvala okungangeni manzi kanye nokuvala isinxephezelo.

(3) Izinqubo ezijwayelekile zenqubo yamalungu esikhungo sokukhiqiza (kufaka phakathi amakhanda esiphelo): Izinqubo zokusebenza kwamalungu esikhungo sokukhiqiza kanye namakhanda esiphelo ziyafana, ezingahlukaniswa zibe yizinkathi ezintathu, okungukuthi ukulungiselela ngaphambi kokukhiqiza, inqubo yokukhiqiza kanye nokuhlolwa kwangemva kokukhiqiza.

①Umsebenzi wokulungiselela ngaphambi kokukhiqiza: Hlola ukuthi izingxenye ezahlukene ziphelele yini ngokwemidwebo. Zonke izingxenye ezithinta uwoyela wekhebula kumele zihlanzwe ngowoyela wekhebula ofanelekile; ikhebula limanzi, futhi kuyadingeka ukuvuma ukuthi akukho umswakama ku-insulation ngaphambi kokuyixhuma.
②Inqubo yokukhiqiza kufanele ifake: ukusaha izintambo ezisele; ukunquma ubude obuthile begobolondo langaphandle lekhebula ngokobude bekhanda lekhebula, ukususa i-asphalt, nokuhlanza ubuso bensimbi; ngokobude bekhanda lekhebula, ukususa ubude obuthile bensimbi ngommese wokukhumula i-aluminium. Isigqoko, susa ungqimba lwe-semiconductor ebusweni bokukhumula; Ukuxhumeka kwe-conductor; Ukugoqa ukuvimbela noma ukwandisa ukuvimbela; Igobolondo lejoyinti ledivayisi, lokwelashwa kokuvala; Ukufaka ukuvimbela, i-sealant engangeni manzi (i-asphalt, i-epoxy resin, njll.).
③Ukuhlolwa: Ukuhlolwa kufanele kwenziwe ngemva kokukhiqiza ukuqinisekisa ukuhambisana nomthetho.
