Isakhiwo esiyisisekelo sekhebula likagesi sakhiwe izingxenye ezine: i-wire core (umqhubi), i-insulation layer, i-shielding layer kanye ne-protective layer. I-insulation layer iyi-electric solidification phakathi kwe-wire core kanye nomhlabathi kanye nezigaba ezahlukene ze-wire core ukuqinisekisa ukudluliswa kwamandla kagesi, futhi iyingxenye ebalulekile yesakhiwo sekhebula likagesi.
Indima yesendlalelo sokufaka umswakama:
Ingaphakathi lekhebula liyi-conductor. Ukuze kuvinjelwe umonakalo wemishini obangelwa ukujikeleza okufushane kwezintambo eziveziwe kanye nokulimala kubantu okubangelwa izintambo ezidlula i-voltage yokuphepha, ungqimba lokuvikela oluvikelayo kumele lufakwe kukhebula. Ukumelana kukagesi komqhubi wensimbi kukhebula kuncane kakhulu, kanti ukumelana kukagesi komshini wokuvikela kuphezulu kakhulu. Isizathu sokuthi kungani umshini wokuvikela ungafakwa i-insulation yingoba: amacala amahle nangalungile kuma-molecule omshini wokuvikela aboshwe ngokuqinile, izinhlayiya ezishajiwe ezingahamba ngokukhululeka zimbalwa kakhulu, kanti ukumelana kukhulu kakhulu, ngakho-ke ngokuvamile, ugesi omkhulu owakhiwe ukunyakaza kwe-free charge ngaphansi kwesenzo sensimu kagesi yangaphandle unganganakwa, futhi ubhekwa njengento engeyona into eqhuba ugesi. Kwabavimba ugesi, kukhona i-voltage yokuqhekeka enikeza ama-electron amandla anele ukuwavusa. Uma i-voltage yokuqhekeka isidlulile, izinto azibe zisavimba ugesi.
Iyini ithonya lokujiya kokufakwa kokushisa okungafaneleki kukhebula?
Nciphisa impilo yesevisi yemikhiqizo yezintambo nekhebula, uma iphuzu elincane le-sheath yekhebula lingahlangabezani nezidingo, ngemva kokusebenza isikhathi eside, ikakhulukazi endaweni efihliwe ngqo, ecwiliswe emanzini, evulekile noma egqwalisayo, ngenxa yokugqwala kwesikhathi eside kwe-medium yangaphandle, izinga lokufakelwa kanye nezinga lomshini lephuzu elincane le-sheath lizoncishiswa. Ukuhlolwa kwe-sheath okuvamile noma ukwehluleka kokufakwa komugqa, iphuzu elincane lingaphulwa, umphumela wokuvikela we-sheath yekhebula uzolahleka. Ngaphezu kwalokho, ukusetshenziswa kwangaphakathi akunakunganakwa, amandla esikhathi eside e-wire nekhebula azokhiqiza ukushisa okuningi, kuzofinyeza impilo yesevisi yentambo nekhebula. Uma ikhwalithi ingekho ezingeni elijwayelekile, kuzobangela umlilo nezinye izingozi zokuphepha.
Ukwandisa ubunzima benqubo yokubeka, enkambisweni yokubeka kudingeka ucabangele ukushiya igebe, ukuze kuqedwe ukushisa okukhiqizwa ngemuva kwamandla entambo nekhebula, ukujiya kwegobolondo kukhulu kakhulu kuzokhulisa ubunzima bokubeka, ngakho ukujiya kwegobolondo kudinga ukuhambisana ngokuqinile nezindinganiso ezifanele, ngaphandle kwalokho ngeke kudlale indima ekuvikeleni ucingo nekhebula. Esinye sezici zekhwalithi yomkhiqizo sibonakala ekhwalithini yokubukeka komkhiqizo. Kungakhathaliseki ukuthi ikhebula lamandla noma ucingo olulula lwendwangu, ikhwalithi yesendlalelo sokufaka umswakama kumele inakwe ekukhiqizweni, futhi kumele ilawulwe futhi ihlolwe ngokuqinile.
Mhlawumbe abantu abaningi bazoba nokungabaza, njengoba indima yesendlalelo sokufaka ugesi inkulu kakhulu, ubuso bekhebula lokukhanyisa kanye nekhebula le-voltage ephansi zimbozwe ngesendlalelo sokufaka ugesi sepulasitiki noma serabha, kanti ikhebula le-voltage ephezulu ensimini alimboziwe nge-insulation.
Ngoba uma i-voltage iphezulu kakhulu, ezinye izinto eziqala ukuvimba ukushisa, njengerabha, ipulasitiki, ukhuni olomile, njll., nazo zizoba yizikhombisi, futhi ngeke zibe nomphumela wokuvimba ukushisa. Ukuvala ukushisa ezintanjeni ezine-voltage ephezulu kuwukuchitha imali nezinsiza. Ubuso bentambo ene-voltage ephezulu abumboziwe nge-insulation, futhi uma ilenga embhoshongweni ophezulu, ingavuza ugesi ngenxa yokuxhumana nombhoshongo. Ukuze kuvinjelwe lesi simo, intambo ene-voltage ephezulu ihlala ilenga ngaphansi kochungechunge olude lwamabhodlela e-porcelain afakwe kahle, ukuze intambo ene-voltage ephezulu ivalwe embhoshongweni. Ngaphezu kwalokho, lapho ufaka izintambo ezine-voltage ephezulu, ungazihuduli phansi. Ngaphandle kwalokho, ngenxa yokungqubuzana phakathi kwentambo nomhlabathi, ungqimba lwe-insulation olubushelelezi ekuqaleni lonakele, futhi kunezimbobo eziningi, ezizokhipha ukuphuma kwe-tip, okuholela ekuvuzeni.
Ingqimba yokuvikela ikhebula isethwe ngokwezidingo zekhebula. Enqubweni yokukhiqiza, abakhiqizi badinga ukulawula ubukhulu bokuvikela ngokuhambisana ngokuqinile nezindinganiso zenqubo, bafinyelele ukuphathwa kwenqubo okuphelele, futhi baqinisekise ikhwalithi yocingo nekhebula.
