Intambo yokukhusela inamagama amabini okukhusela, njengoko igama lisitsho yintambo yokudlulisa enokumelana nokuphazamiseka kwe-electromagnetic yangaphandle eyenziwe yi-shielding layer. Oko kubizwa ngokuba yi-"shielding" kwisakhiwo sentambo kukwayindlela yokuphucula ukusasazwa kwamasimi ombane. I-conductor yentambo yenziwe ngeentambo ezininzi zentambo, okulula ukwenza umsantsa womoya phakathi kwayo kunye ne-insulation layer, kwaye umphezulu we-conductor awugudileyo, nto leyo eya kubangela uxinzelelo lwe-electrical field.
1. Umaleko wokukhusela intambo
(1). Yongeza umaleko wokukhusela wezinto eziqhuba kancinci kumphezulu womqhubi, ohambelana nomqhubi okhuselekileyo kwaye unxibelelana kakuhle nomaleko wokukhusela, ukuze kuthintelwe ukukhupha okungaphelelanga phakathi komqhubi kunye nomaleko wokukhusela. Olu maleko wokukhusela ukwaziwa njengomaleko wokukhusela wangaphakathi. Kunokubakho nezikhewu kunxibelelwano phakathi komphezulu wokukhusela kunye neshelufu, kwaye xa intambo igobile, umphezulu wokukhusela intambo ye-oyile-paper kulula ukubangela iintanda, ezizinto ezibangela ukukhupha okungaphelelanga.
(2). Yongeza umaleko wokukhusela wezinto eziqhuba kancinci kumphezulu womaleko wokukhusela, onxibelelana kakuhle nomaleko wokukhusela okhuselekileyo kwaye unamandla alinganayo neshedi yesinyithi, ukuze kuthintelwe ukukhupha inxalenye phakathi komaleko wokukhusela kunye neshedi.
Ukuze kuqhutywe ngokulinganayo umbindi kwaye kufakwe i-insulation kwi-electrical field, iintambo zamandla ze-6kV nangaphezulu zinomaleko we-conductor shield kunye nomaleko we-insulation shield, kwaye ezinye iintambo ze-low-voltage azinawo umaleko we-shield. Kukho iintlobo ezimbini zee-shield layers: i-semi-conductive shielding kunye ne-metal shielding.
2. Intambo ekhuselweyo
Umaleko wokukhusela wale ntambo ugqunywe kakhulu kwinethiwekhi yeengcingo zesinyithi okanye ifilimu yesinyithi, kwaye kukho iindlela ezahlukeneyo zokukhusela enye kunye nokukhusela okuninzi. Isihlangu esinye sibhekisa kwinethi yesihlangu esinye okanye ifilimu yesihlangu, esinokusonga intambo enye okanye ezingaphezulu. Imo yokukhusela okuninzi yinethiwekhi ezininzi zokukhusela, kwaye ifilimu yokukhusela ikwintambo enye. Ezinye zisetyenziselwa ukwahlukanisa ukuphazamiseka kwe-electromagnetic phakathi kweengcingo, kwaye ezinye zikhusela ngamaleko amabini asetyenziselwa ukuqinisa isiphumo sokukhusela. Indlela yokukhusela kukumisa umaleko wokukhusela ukuze kwahlulwe i-voltage yokuphazamiseka ebangelwa yintambo yangaphandle.
(1) Isikhuselo esingenamthungo
Umaleko wekhaka elihamba ngombane udla ngokucwangciswa kumphezulu wangaphandle we-conductive wire core kunye nomphezulu wangaphandle we-insulating layer, ezibizwa ngokuba yi-inner semi-conductive shield layer kunye ne-outer semi-conductive shield layer ngokulandelelana. Umaleko we-semi-conductive shielding wenziwe ngezinto ezihamba ngombane ezinokumelana okuphantsi kakhulu kunye nobukhulu obuncinci. Umaleko we-inner semi-conductive shielding wenzelwe ukulingana intsimi yombane kumphezulu wangaphandle we-conductor core kwaye uphephe ukukhutshwa okuncinci kwe-conductor kunye ne-insulation ngenxa yomphezulu ongalinganiyo we-conductor kunye nomsantsa womoya obangelwa yi-stranded core. Umaleko we-interior semi-conductive shield unxibelelana kakuhle nomphezulu wangaphandle we-insulation layer, kwaye uhambelana ne-metal sheath ukuze uphephe ukukhutshwa okuncinci kwi-metal sheath ngenxa yeziphene ezifana nokuqhekeka kumphezulu we-cable insulation.
(2) Ukukhusela isinyithi
Kwiintambo zamandla zevolthi ephakathi nephantsi ezingenazo iijakethi zesinyithi, kufuneka kongezwe umaleko wekhaka lesinyithi ukongeza kumaleko wekhaka elihamba kancinci. Umaleko wekhaka lesinyithi uhlala usongelwaiteyiphu yobheduokanye ucingo lobhedu, oludlala indima yokukhusela intsimi yombane.
Ngenxa yokuba umbane ohamba ngentambo yamandla mkhulu kakhulu, intsimi yemagnethi iya kuveliswa ijikeleze umbane, ukuze ingachaphazeli ezinye izinto, ngoko ke ungqimba lokukhusela lunokukhusela le ntsimi ye-electromagnetic kwintambo. Ukongeza, ungqimba lokukhusela intambo lunokudlala indima ethile ekukhuseleni umhlaba. Ukuba umongo wentambo wonakele, umbane ovuzayo unokuhamba ngokuhamba kwe-laminar yokukhusela, njengenethiwekhi yokukhusela umhlaba, ukuze udlale indima ekukhuseleni ukhuseleko. Kuyabonakala ukuba indima yongqimba lokukhusela intambo isenkulu kakhulu.
