Umaleko okhuselayo wesinyithi sisakhiwo esiyimfunekoi-voltage ephakathi(3.6/6kV∽26/35kV) iintambo zombane eziqhagamshelwe ngepolyethylene ezigqunyiweyo. Ukuyila ngokufanelekileyo ukwakhiwa kwekhaka lentsimbi, ukubala ngokuchanekileyo i-short-circuit current ikhuselo liya kuthwala, kunye nokuphuhlisa ubuchule obufanelekileyo bokucubungula ikhaka kubalulekile ekuqinisekiseni umgangatho weentambo ezidibeneyo kunye nokhuseleko lwenkqubo yonke yokusebenza.
Inkqubo yokuKhusela:
Inkqubo yokukhusela kwimveliso yentambo ye-voltage ephakathi ilula. Nangona kunjalo, ukuba ingqalelo ayihlawulwanga kwiinkcukacha ezithile, kunokukhokelela kwimiphumo enzima yomgangatho wentambo.
1. Tape yobheduInkqubo yokuKhusela:
Iteyiphu yobhedu esetyenziselwa ukukhusela kufuneka ifakwe ngokupheleleyo iteyiphu yobhedu ethambileyo ngaphandle kweziphene ezifana neencam ezigobileyo okanye iintanda kumacala omabini.Iteyiphu yobheduukuba kunzima kakhulu kungonakalisaumaleko we-semiconductive, ngelixa iteyiphu ethambileyo kakhulu inokushwabana ngokulula. Ngexesha lokusonga, kubalulekile ukuseta i-engile yokusonga ngokuchanekileyo, lawula ukuxinezeleka ngokufanelekileyo ukuphepha ukuqina kakhulu. Xa iintambo zenziwe amandla, ukugquma kwenza ubushushu kwaye kwande kancinci. Ukuba i-tape yobhedu ihlanganiswe ngokuqinileyo, inokuthi ifakwe kwi-insulating shield okanye ibangele ukuba i-tape iphule. Izinto ezithambileyo kufuneka zisetyenziswe njenge-padding kumacala omabini e-reel yokuthatha umatshini wokukhusela ukukhusela nawuphi na umonakalo onokwenzeka kwi-tape yobhedu ngexesha lamanyathelo alandelayo kwinkqubo. Amalungu eteyiphu yobhedu kufuneka adityaniswe ngamabala, angathengiswa, kwaye ngokuqinisekileyo angadityaniswa kusetyenziswa iiplagi, iiteyipu ezincamathelayo, okanye ezinye iindlela ezingezizo eziqhelekileyo.
Kwimeko yokukhusela i-tape yobhedu, ukudibanisa kunye ne-semiconductive layer kunokubangela ukubunjwa kwe-oxide ngenxa yendawo yokudibanisa, ukunciphisa uxinzelelo loqhagamshelwano kunye nokuchasana ngokuphindwe kabini xa i-metal shielding layer idlula ukwanda kwe-thermal okanye i-contraction kunye nokugoba. Uqhagamshelwano olubi kunye nokwandiswa kwe-thermal kunokukhokelela kumonakalo othe ngqo ngaphandleumaleko we-semiconductive. Uqhagamshelwano olufanelekileyo phakathi kwetape yobhedu kunye ne-semiconductive layer ibalulekile ukuze kuqinisekiswe umgangatho osebenzayo. Ukushisa, ngenxa yokwandiswa kwe-thermal, kunokubangela ukuba i-tape yobhedu yandise kwaye iguqule, yonakalise i-semiconductive layer. Kwiimeko ezinjalo, i-tape ye-copper edibeneyo edibeneyo okanye engafanelekanga iyakwazi ukuthwala umjelo wokutshaja ukusuka kwisigxina esingekho phantsi ukuya ekupheleni komhlaba, okukhokelela ekugqithiseni kunye nokuguga ngokukhawuleza kwinqanaba le-semiconductive kwindawo yokuqhawula i-tape yobhedu.
2. Inkqubo yeCopper Wire Shielding:
Xa usebenzisa isikhuselo socingo sobhedu esinenxeba elikhululekileyo, ukusongela iingcingo zobhedu ngokuthe ngqo kumphezulu wekhaka elingaphandle kunokubangela ukusonga okuqinileyo, okunokonakalisa isigqumathelo kwaye kukhokelele ekuqhawukeni kwentambo. Ukujongana nale nto, kuyimfuneko yokongeza i-1-2 ye-tape ye-semiconductive ye-nayiloni ejikeleze umaleko wekhaka elikhutshiweyo le-semiconductive emva kokukhutshwa.
Iikheyibhile ezisebenzisa inxeba elikhululekileyo lokukhusela ucingo lobhedu azikhathazwa kukwakheka kweoksidi efunyenwe phakathi kweengqimba zeteyiphu yobhedu. Ukukhusela ucingo lwe-Copper kunokugoba okuncinci, i-deformation encinci yokwandisa i-thermal, kunye nokunyuka okuncinci kokuchasana noqhagamshelwano, konke oku negalelo ekuphuculeni ukusebenza kombane, oomatshini kunye ne-thermal ekusebenzeni kwentambo.
