Izixhumi ziyingxenye ebalulekile yehhanisi lezintambo zokuxhuma nokuvikela izintambo zokubopha.Ukuqinisekisa ukudluliswa okujwayelekile kwamandla namasignali, ukukhethwa kwezixhumi kubalulekile.Isixhumi sezintambo zezintambo zezimoto siyingxenye ebalulekile esetshenziselwa ukuxhuma isekethe kagesi wemoto.Umsebenzi wayo ukuxhuma izifunda ezihlukahlukene kumjikelezo kagesi wemoto ukuze unikeze indlela enhle yokugeleza kwamanje nokudluliswa kwesignali kagesi, ukuze kuqashelwe ukusebenza okuvamile nokuzinzile kwesekethe.Emhlanganweni wemoto yonke, isixhumi sidlala indima ebalulekile kuyo.
1 Izakhiwo zikagesi
Isixhumi siyingxenye esetshenziselwa ukuxhuma izintambo zikagesi, ngakho ukusebenza kwayo kagesi kufanele kucatshangelwe kuqala.
Ukusebenza kukagesi ikakhulukazi kubheka izici ezifana ne-voltage, i-current, ukumelana ne-insulation.
Ngaphansi kwezimo ezijwayelekile, isilinganiso samanje sesixhumi ukuhlola ukusebenza kwaso ukumelana nokushisa ekamelweni lokushisa.Uma izinga lokushisa lidlula inani elibekiwe, lizobangela ukwehluleka kwesekethe kagesi.Ngokuvamile, izinga lamanje elilinganiselwe linikezwa kumanuwali womkhiqizo, okungamanje okusebenza kakhulu ezingeni lokushisa legumbi.Ezixhunyweni ezinezimbobo eziningi, ikakhulukazi emisinga emikhulu, ukukhethwa kwangempela kufanele kuncishiswe ngokwenani lezimbobo kusixhumi.Ukwengeza, ngokombono wokumelana nokuxhumana kwesixhumi, ukumelana nokuxhumana okukalwa ngaphansi kwezimo zokuhlola zokuphikiswa kokuxhumana okuphansi kufanele kucatshangelwe kumasekhethi amasignali amancane.Kulezo zixhumi zesekethe ezinamasignali amancane ezingakwazi ukwaneliswa amatheminali afakwe ngothayela avamile, cabanga Sebenzisa izimbotshana zensimbi eziyigugu njengesiliva noma igolide ukuze uzixazulule.
Okokugcina, ngokusebenza kwe-insulation yesixhumi, kubhekiselwa kakhulu ekuphikisweni kokufakwa kwe-insulation namandla e-dielectric e-insulation.Inani elithile lingatholwa ngesilinganiso.Kudingekile ukwenza ukukhetha ngokusekelwe ezintweni zokuvikela ezisetshenziselwa isixhumi nendawo yokusebenza.
2 Izakhiwo zikamshini
Izici zomshini zesixhumi ngokuyinhloko zihlanganisa amandla okufaka, ukuphila komshini, namandla okuhlangana namandla okuhlukanisa phakathi kwetheminali nesheath, ephakeme kuno-75N kusixhumi.Ngakho-ke, ngaphansi kwesisekelo sokuqinisekisa amandla ajwayelekile avuliwe, amandla amancane okufaka, angcono.Impilo yobumishini isho inani lezikhathi lapho ingaxhunywa khona futhi inqanyulwe.
Impilo yemishini yesixhumi esijwayelekile sikagesi imvamisa izikhathi ezingama-500-1000, kuyilapho isixhumi semoto sihlangabezana nezidingo ze-conductivity evamile ngemva kwezikhathi eziyi-10 zokuxhuma nokukhipha i-plug, kanye nokusebenza okuqhutshwayo kwamatheminali ane-silver-plated kuvamile ngemva kwezikhathi ezingu-30 zokuxhuma. nokukhipha ipulaki.Ngemva conductivity kagesi kuyinto evamile.Amandla okukhwelana phakathi kwetheminali kanye nesheath athintwa ububanzi bezintambo ezigoqayo zetheminali.Uma ingaphansi kuka-1mm2, amandla okukhwelana awekho ngaphansi kuka-15N, futhi uma inkulu kuno-1mm2, amandla okukhwelana awekho ngaphansi kuka-30N.Amandla okuhlukanisa phakathi kwetheminali nesheath ahlobene nosayizi wesixhumi.Ezixhunyweni ezinezincazelo ezingaphansi kuka-2.8 nangaphezulu kuka-2.8, amandla okuhlukanisa kufanele abe mkhulu kuno-40N no-60N.
3 Ukusebenza kwemvelo
Izixhumi zezimoto zisetshenziswa kakhulu, futhi izingxenye ezihlukene zemoto zivame ukuba nezindawo ezihluke kakhulu.Ngakho-ke, ekukhethweni kwezixhumi zezimoto, izici zemvelo zidlala indima ebalulekile yokubhekisela.Izici zemvelo ikakhulukazi zihlanganisa izinga lokushisa, umswakama, ukungenwa kwamanzi nokuvikela uthuli, njll. Izinga lokushisa elizungezile lihlukaniswe ngamamaki angu-5, futhi izinga lokushisa lokuhlola ngokuvamile liphakeme kancane kunezinga lokushisa elizungezile.
Lapho ukhetha, qala ngokunquma izinga lokushisa elihambisanayo ngokwendawo, bese wenza ukukhetha okunengqondo kakhulu ngokomgodla kanye nempahla yokugcina.Umswakama wesixhumi akufanele ube phezulu kakhulu, futhi kulula ukubangela inkinga yesifunda esifushane endaweni enomswakama.Ngakho-ke, izixhumi ezivaliwe kufanele zisetshenziswe ezindaweni ezinomswakama.
Izikhundla ezihlukene emotweni zinezinga elihlukile lomswakama womoya kanye namazinga okuphazamiseka kwamanzi, futhi izinga elidingekayo lokungangeni kwamanzi nalo lihlukile.Ikhompathimenti yenjini, i-chassis kanye nengxenye engezansi yenjini, isihlalo kanye nengxenye engezansi yomnyango eduze no-chassis kufanele ngokujwayelekile kukhethe umgodla ongenamanzi.Ezingxenyeni ezifana nengaphakathi le-cab, iminyango, nengxenye engenhla yesihlalo, izixhumi ezingenamanzi zingacatshangelwa.Ngokuvamile, ngokuthuthukiswa kokusebenza okungangeni manzi, ukusebenza kokuvikela uthuli nakho kuzokhuphuka ngokufanele.
