Izintambo zokuxhumana eziyimvamisa ephezulu kanye nokulahlekelwa okuphansi ngokuvamile zenziwa nge-polyethylene enegwebu noma i-polypropylene enegwebu njengezinto zokuvikela, izintambo ezimbili ezivikelayo kanye nocingo oluphansi (imakethe yamanje inabakhiqizi abasebenzisa izindawo ezimbili eziphindwe kabili) emshinini wokusonta, ukusonga ucwecwe lwe-aluminium kanye netheyiphu yenjoloba ye-polyester ezungeze i-insulating core core kanye nenqubo yokulawula umugqa kagesi, inqubo yokulawula izintambo zikagesi kanye nenqubo yokulawula umugqa womhlabathi. izidingo kanye nethiyori yokudlulisela.
Imfuneko yomqhubi
Ku-SAS, okuyilayini yokudlulisela imvamisa ephezulu, ukufana kwesakhiwo kwengxenye ngayinye kuyisici esibalulekile ekunqumeni imvamisa yokudlulisela yekhebula. Ngakho-ke, njengomqhubi we-high-frequency transmission line, ubuso buyindilinga futhi bushelelezi, futhi isakhiwo sangaphakathi sokuhlelwa kwe-lattice siyafana futhi sizinzile ukuze kuqinisekiswe ukufana kwezakhiwo zikagesi ekuqondeni ubude; Umqhubi kufanele futhi abe nokumelana okuphansi kwe-DC; Ngesikhathi esifanayo kufanele kugwenywe ngenxa yocingo, imishini noma amanye amadivaysi okubangelwa ukugoba kwe-conductor yangaphakathi ngezikhathi ezithile noma ukugoba okungezona ngezikhathi ezithile, ukuwohloka nokulimala, njll., emugqeni wokudlulisa we-high-frequency, ukumelana komqhubi kuyisici esiyinhloko esibangela ukuncishiswa kwekhebula (amapharamitha aphezulu-imvamisa eyisisekelo ingxenye ye-01- imingcele ephansi yokunciphisa), kunezindlela ezimbili zokumelana nomqhubi wokunciphisa umqhubi we-conductor, ukukhushulwa kokumelana nomqhubi. izinto zokwakha. Ngemuva kokwenyuka kobubanzi be-conductor, ukuze kuhlangatshezwane nezidingo ze-impedance yesici, ububanzi bangaphandle bokufakwa kwe-insulation kanye nobubanzi bangaphandle bomkhiqizo oqediwe buyanda ngokulinganayo, okuholela ekwenyukeni kwezindleko kanye nokucubungula okungalungile. Ngokombono, kusetshenziswa i-conductor yesiliva, ububanzi bangaphandle bomkhiqizo oqediwe buzoncishiswa, futhi ukusebenza kuzothuthukiswa kakhulu, kodwa ngenxa yokuthi intengo yesiliva iphakeme kakhulu kunentengo yethusi, izindleko ziphezulu kakhulu ekukhiqizeni ngobuningi, ukuze kubhekwe intengo nokumelana okuphansi, sisebenzisa umphumela wesikhumba ukuklama umqhubi wekhebula. Njengamanje, ukusetshenziswa kwamakhondatha ethusi ethayela e-SAS 6G kungahlangabezana nokusebenza kukagesi, kuyilapho i-SAS 12G ne-24G isiqalile ukusebenzisa amakhondaktha anesiliva.
Uma kunenkambu yamanje eshintshanayo noma eshintshanayo kagesi ku-conductor, ukusatshalaliswa kwamanje ngaphakathi kwekhondakta kuzohluka. Njengoba ibanga elisuka endaweni ye-conductor likhula kancane kancane, ukuminyana kwamanje ku-conductor kuncipha ngokuqhubekayo, okungukuthi, i-current in conductor izogxila ebusweni bomqhubi. Kusukela endizeni eguquguqukayo i-perpendicular kuya ekuqondeni kwe-current, ukuqina kwamanje kwengxenye emaphakathi yomqhubi ngokuyisisekelo kunguziro, okungukuthi, cishe akukho ukugeleza kwamanje, futhi ingxenye kuphela emaphethelweni ka-conductor izoba nama-subcurrents. Kalula nje, i-current igxile engxenyeni "yesikhumba" yomqhubi, ngakho ibizwa ngokuthi umphumela wesikhumba. Isizathu salo mphumela ukuthi insimu ye-electromagnetic eshintshayo ikhiqiza insimu kagesi ye-vortex ngaphakathi kwe-conductor, ehlanjululwa yi-current yasekuqaleni. Umphumela wesikhumba wenza ukumelana komqhubi kukhule ngokukhula kwemvamisa yokushintshana kwamanje, futhi kuholela ekwehlisweni kokusebenza kahle kokudluliselwa kwezintambo zamanje, izinsiza zensimbi ezidlayo, kodwa ekwakhiweni kwezintambo zokuxhumana ezisezingeni eliphezulu, lesi simiso singasetshenziswa ukunciphisa ukusetshenziswa kwensimbi ngokusebenzisa i-plating yesiliva phezulu ngaphansi kwesisekelo sokuhlangabezana nezidingo ezifanayo zokusebenza, ngaleyo ndlela kuncishiswe izindleko.
Isidingo se-insulation
Ngokufanayo nezidingo ze-conductor, i-insulating medium kufanele futhi ifane, futhi ukuze kutholwe i-dielectric engaguquki ephansi kanye nokulahlekelwa kwe-dielectric I-angle tangent value, izintambo ze-SAS ngokuvamile zisebenzisa ukufakwa kwegwebu. Uma idigri yokugwaza ingaphezulu kuka-45%, kunzima ukufeza igwebu lamakhemikhali, futhi idigri yegwebu alizinzile, ngakho-ke ikhebula elingaphezu kuka-12G kufanele lisebenzise ukufakwa kwamagwebu ngokomzimba. Njengoba kukhonjisiwe emfanekisweni ongezansi, lapho idigri ecwebezelayo ingaphezulu kuka-45%, ingxenye yokukhihliza amagwebu ngokomzimba kanye nokukhipha amagwebu kwamakhemikhali okubonwa ngaphansi kwesibonakhulu, izimbotshana ezinamagwebu ziya ngokuya ziba zincane, kuyilapho izimbotshana ezinamagwebu zamakhemikhali ziba zincane futhi zikhudlwana:
ukukhihliza amagwebu ngokomzimba Amakhemikhaliekhihliza amagwebu
