Iintambo zombane ophezuluzibalulekile koomatshini beX-reyi.Ngaba uqhelene nesakhiwo seentambo zombane ophezulu?Namhlanje siza kuthetha ngokufutshane malunga nendima ye-semiconductor layer kwi-high-voltage cables.
Umaleko wesemiconductor kwiintambo yombane ophezuluyinto esihlala siyibiza ngokuthi "ukukhusela", eyona nto ingumlinganiselo wokuphucula ukuhanjiswa kwendawo yombane.I-cable conductor yenziwa ngokujija iingcingo ezininzi, kwaye kulula ukwenza i-gap yomoya phakathi kwayo kunye ne-insulating layer.Ukongezelela, umphezulu we-conductor awululanga, oya kubangela ukugxininiswa kwentsimi yombane.
Ngoko ke, kuyimfuneko yokongeza i-shielding layer ye-semiconducting material ebusweni bomqhubi, ohambelana ne-conductor ekhuselekileyo kwaye unoqhagamshelwano olufanelekileyo kunye ne-insulating layer, ukwenzela ukuba ugweme ukukhutshwa okuyingxenye phakathi komqhubi kunye ne-insulating layer.Ikhaka.
Kusenokubakho umsantsa phakathi komphezulu we-insulating kunye ne-sheath contact, eyona nto ibangela ukukhupha inxalenye.Ngoko ke, i-shielding layer ye-semiconducting material yongezwa kumphezulu we-insulating layer, ononxibelelwano oluhle kunye ne-shielded insulating layer kwaye idibene kakuhle kunye nentsimbi yokukhusela isinyithi.Ijacket i-equipotential ukuphepha ukukhutshwa okuyingxenye phakathi kwe-insulating layer kunye nejacket, kwaye olu luhlu lukhuselwe njengoluhlu lwangaphandle lokukhusela.
Kwiintambo ezikhutshiweyo ezikhutshiweyo ngaphandle kwee-sheaths zetsimbi, ngaphezu kwe-semi-conductive shielding layer, i-metal shielding layer ehlanganiswe nge-tape yobhedu okanye ucingo lobhedu kufuneka yongezwe.Umsebenzi walo mgca wokukhusela isinyithi kukudlula i-capacitive current ngexesha lokusebenza okuqhelekileyo;xa isixokelelwano Xa kusenzeka isiphaluka esifutshane, sisebenza njengejelo lomjelo wesekethe emfutshane kwaye ikwakhusela indawo yombane.
Ukuba olu luhlu lwangaphandle lwe-semiconducting kunye nokukhusela ubhedu alukho kwikhebula, ithuba lokuqhekeka kwe-insulation phakathi kwee-cores zentambo ezintathu ziphezulu kakhulu.Ngoko ke, xa kuthengwaiintambo zombane ophezulu, qiniseka ukuba ugcine amehlo akho evulekile kwaye uthenge iimveliso ezikhuselekileyo nezifanelekileyo.
