Ikhebula elivikelwe, njengoba igama libonisa, ikhebula elinamandla okuphazamisa we-electromagnetic anti-yangaphandle akhiwa ngendlela yekhebula lokuhambisa elinesendlalelo sokuhambisa. Okubizwa ngokuthi "Ukuvikelwa" kwisakhiwo samakhebula nakho kuyisilinganiso sokuthuthukisa ukusatshalaliswa kwamasimu kagesi. Umqhubi wekhebula wahlanganiswa nemicu eminingi yocingo, okulula ukwakha igebe lomoya phakathi kwalo kanye nongqimba wokufakelwa, futhi indawo yomqalisi ayibushelelezi, okuzokwenza ukugcwala kwensimu kagesi.
Ungqimba oluvikelekile lwe-1.Cable
(1). Faka ungqimba lwe-Shielting lwe-Semi-Riptive impahla ebusweni bomqhubi, obuhlolisisa nomqhubi wesivikelo kanye nokuxhumana okuhle nongqimba lokufakwa, ukuze ugweme ukukhipha okuhlukile phakathi komqhubi kanye nongqimba olungenacala. Le ungqimba ye-Shieveng yaziwa nangokuthi ingqimba yangaphakathi yokuvikela. Kungenzeka futhi kube nezikhala lapho uthintana phakathi kwendawo yokufakelwa kanye ne-sheath, futhi lapho ikhebula ligobile, indawo ephephelo yamafutha okufakwayo kulula ukuyibangela ukuqhekeka, okuyisici ebangela ukukhishwa okuyingxenye.
(2). Faka ungqimba oluvikelekile lwe-semi-pressive impahla ebusweni besendlalelo sokufakelwa, esithintana kahle nongqimba oluvikelekile lokufakelwa kanye namathuba alinganayo nge-metal sheath, ukuze ugweme ukukhipha okuhlukile phakathi kongqimba olungenayo kanye nomhlanga.
Ukuze uqhube ngokulinganayo umnyombo futhi ungenisa inkambu kagesi, amakhebuli angama-6kv nangaphezulu kwamakhamera aphakathi nendawo aphezulu ngokuvamile anomqeqeshi wesihlangu ungqimba kanye nesendlalelo sezitshalo eziphansi, futhi ezinye izintambo zamandla aphansi azinalo ungqimba lwesihlangu. Kunezinhlobo ezimbili zezendlalelo zokuvikela: Ukuvikela okuvuthayo kanye nokuvikelwa kwensimbi.
2. Ikhebula elivikelwe
Isendlalelo sale khebula lelo ikhebula kakhulu ifakwe kwinethiwekhi yezintambo zensimbi noma ifilimu lensimbi, futhi kunezinhlobonhlobo zezindlela ezahlukahlukene zokuvikelwa okukodwa nokuvikelwa okuningi. Isihlangu esisodwa sisho ifilimu eyodwa yesihlangu noma isihlangu, esingasonga izintambo eyodwa noma eziningi. Imodi yokuvikelwa okuhlukahlukene iyinhlangano yamanethiwekhi okuvikela, nefilimu yokuvikela kukhebula elilodwa. Ezinye zisetshenziselwa ukuhlukanisa amandla kagesi phakathi kwezintambo, kanti ezinye ziyizinsuku ezibunjiwe eziphindwe kabili ezisetshenziselwa ukuqinisa umphumela wokuvikelwa. Indlela yokuvikelwa ukuvikela ungqimba lokuvikelwa ukuhlukanisa i-voltage efakiwe yokuphazamiseka yocingo lwangaphandle.
(1) .Semi-Shield
Ingqimba ye-Semi-Rightise Shied ijwayele ukuhlelwa endaweni yangaphandle yomugqa we-wire ophethe kanye nomhlaba ongaphandle wesendlalelo sokufakelwa, ngokulandelana okubizwa ngokuthi yingqimba yangaphakathi yokuvikelwa kwe-semi kanye nesendlalelo sangaphandle sokuqhuma okuqhutshwa yisikhathi sangaphandle. Isendlalelo sokuvikela esiqhuma se-semi-sakhiwa ngento evuthayo enobunzima obuphansi kakhulu nobukhulu obuncane. Isendlalelo sangaphakathi se-Semi-Shieukering senzelwe ukufana nenkambu kagesi ebusweni bangaphandle lomqhubi womqhubi wesifundo futhi bagweme ukukhipha okuyingxenye komqhubi kanye nokufakwa kwegebe elingalinganiswanga lomqhubi kanye negebe lomoya elibangelwa umnyombo we-conductor ne-air. Isihlangu se-semi-sokuqhutshwa kwangaphandle sixhumana kahle ne-wanger ebusweni, futhi i-equequelial ngensimbi ye-sheath ukugwema ukukhipha okuyingxenye nge-metal sheath ngenxa yemifantu ebusweni be-cable.
(2). Isihlangu Sensimbi
Okwezintambo zamandla aphakathi nendawo futhi eziphansi ngaphandle kwama-sheaths wensimbi, ngaphezu kokubeka ungqimba lwe-semi-aqhubela isihlangu, kodwa futhi engeza ungqimba lwensimbi lwensimbi. Ingqimba yensimbi yensimbi ivame ukumbozwa yiitheyiphu yethusinoma ucingo lwethusi, oludlala indima ngokuvikela insimu kagesi.
Ngoba okwamanje ngentambo yamandla kukhulu, amandla kazibuthe azokwenziwa azungeze okwamanje, ukuze angathinteki ezinye izinto, ngakho-ke ungqimba lokuvikela lungavikela le nkambu ye-electromagnetic kukhebula. Ngaphezu kwalokho, ungqimba lwekhebula lokuvikela ikhebula lungadlala indima ethile ekuvikelweni okusekelwe. Uma umnyombo wekhebula ulimele, okuvuthiwe kwamanje kungageleza kugeleza ngomamaminani we-laminar, njengenethiwekhi ephansi, ukudlala indima ekuvikelweni kwezokuphepha. Kuyabonakala ukuthi iqhaza le-Cable Shiely ungqimba lise likhulu kakhulu.
