Iintambo zonxibelelwano oluhamba rhoqo kunye nelahleko ephantsi ngokubanzi zenziwe nge-polyethylene enogwebu okanye i-polypropylene enogwebu njengesixhobo sokugquma, iingcingo ezimbini ezikhuselayo ezingundoqo kunye nocingo oluphantsi (imarike yangoku inabo abavelisi abasebenzisa umhlaba ophindwe kabini) kumatshini wokujija, ukusonga ifoyile yealuminiyam kunye neteyiphu yerabha ye-polyester ejikeleze inkqubo yokugquma i-insulating core kunye nenkqubo yoyilo lombane, inkqubo yoyilo lombane kunye noyilo lombane olugqithisiweyo. iimfuno kunye nethiyori yosasazo.
Imfuneko yomqhubi
Kwi-SAS, ekwangumgca we-high-frequency transmission line, ukufana kwesakhiwo senxalenye nganye yinto ephambili ekunqumeni ukuphindaphinda kokuhanjiswa kwentambo. Ngoko ke, njengomqhubi we-high-frequency transmission line, ubuso bujikelezileyo kwaye bugudileyo, kwaye i-lattice yokuhlelwa kwe-lattice yangaphakathi ifana kwaye izinzile ukuqinisekisa ukufana kweempawu zombane kwindlela yobude; I-conductor kufuneka kwakhona ibe nokumelana okuphantsi kwe-DC; Kwangaxeshanye kufuneka ugweme ngenxa yocingo, izixhobo okanye ezinye izixhobo ezibangelwa ukugoba kwangaphakathi kwe-conductor periodic okanye ukugoba okungeyo-periodic, deformation kunye nomonakalo, njl., kwi-high-frequency transmission line, ukuxhathisa umqhubi yeyona nto ibangela ukuba ikhebula lithintelwe (i-high-frequency parameters basic part 01- attenuation parameters), kukho iindlela ezimbini zokuxhathisa umqhubi we-conductor, ukunyusa ukuchasana kwe-conductor ukunyuswa kwe-conductor. izixhobo. Emva kokuba i-conductor diameter inyuka, ukuze kuhlangatyezwane neemfuno ze-impedance yeempawu, i-diameter yangaphandle ye-insulation kunye ne-diameter yangaphandle yemveliso egqityiweyo yanda ngokuhambelanayo, okubangela ukunyuka kweendleko kunye nokungahambi kakuhle. Ngokwethiyori, usebenzisa i-conductor yesilivere, i-diameter yangaphandle yemveliso egqityiweyo iya kuncitshiswa, kwaye ukusebenza kuya kuphuculwa kakhulu, kodwa ngenxa yokuba ixabiso lesilivere liphezulu kakhulu kunexabiso lobhedu, ixabiso liphezulu kakhulu kwimveliso yobuninzi, ukuze kuthathelwe ingqalelo ixabiso kunye nokumelana okuphantsi, sisebenzisa umphumo wesikhumba ukuyila umqhubi wentambo. Okwangoku, ukusetyenziswa kwee-conductor zethusi ezikhonkxiweyo ze-SAS 6G zinokuhlangabezana nokusebenza kombane, ngelixa i-SAS 12G kunye ne-24G sele iqalile ukusebenzisa abaqhubi besilivere.
Xa kukho indawo etshintshayo yangoku okanye etshintshanayo ye-electromagnetic kwi-conductor, ukuhanjiswa kwangoku ngaphakathi komqhubi kuya kungalingani. Njengoko umgama osuka kumqhubi we-conductor ukhula ngokuthe ngcembe, ukuxinana kwangoku kwi-conductor kuncipha ngokukhawuleza, oko kukuthi, i-current in conductor iya kugxininisa ebusweni bomqhubi. Ukusuka kwi-transverse plane perpendicular to the direction of the current, intensity yangoku yendawo esembindini yeconductor ngokusisiseko ingu-zero, oko kukuthi, phantse akukho nto ihambayo ngoku, kwaye kuphela inxalenye ekumda womqhubi iya kuba ne-subcurrents. Ukubeka nje, i-current igxininiswe kwinxalenye "yesikhumba" yomqhubi, ngoko kuthiwa yimpembelelo yesikhumba. Isizathu sesi siphumo kukuba intsimi ye-electromagnetic eguqukayo ivelisa indawo yombane ye-vortex ngaphakathi kwe-conductor, echithwa ngumbane wangaphambili. Isiphumo solusu senza ukwanda kokumelana komqhubi kunye nokwanda kokuphindaphindeka kokutshintshana kwangoku, kwaye kukhokelela ekunciphiseni ukusebenza kakuhle kokuhanjiswa kocingo lwangoku, ukusetyenziswa kwezixhobo zetsimbi, kodwa kuyilo lweentambo zonxibelelwano ezijikelezayo, lo mgaqo ungasetyenziselwa ukunciphisa ukusetyenziswa kwesinyithi ngokusebenzisa isilivere yokubeka phezu komhlaba phantsi kwesiseko sokuhlangabezana neemfuno zokusebenza ezifanayo, ngaloo ndlela kuncitshiswa iindleko.
Imfuneko ye-insulation
Ngokufanayo neemfuno zomqhubi, i-insulating medium kufuneka ibe yinto efanayo, kwaye ukuze ufumane i-dielectric ephantsi rhoqo kunye nelahleko ye-dielectric Angle tangent value, iintambo ze-SAS ngokubanzi zisebenzisa ukugquma amagwebu. Xa idigri yogwebu ingaphezulu kwe-45%, kunzima ukufikelela kwimichiza egwebu amagwebu, kwaye iqondo lokugwebu alizinzanga, ngoko ke intambo engaphezulu kwe-12G kufuneka isebenzise ukugquma amagwebu ngokwasemzimbeni. Njengoko kubonisiwe kulo mzobo ungezantsi, xa idigri yogwebu ingaphezulu kwe-45%, icandelo logwebu lomzimba kunye nogwebu lwekhemikhali olujongwe phantsi kwemakroskopu, iipores ezinogwebu ezibonakalayo ziya zisiba zincinci, ngelixa imichiza ephuphuma ugwebu incinci kwaye inkulu:
