I-SAS(Serial Attached SCSI) isizukulwane esisha sobuchwepheshe be-SCSI.Kuyafana nama-hard disk we-Serial ATA(SATA).Isebenzisa ubuchwepheshe be-Serial ukuze kuzuzwe isivinini sokudlulisa esiphezulu futhi kuthuthukiswe indawo yangaphakathi ngokunciphisa ulayini wokuxhuma.Ngocingo olungenalutho, okwamanje ikakhulukazi kusukela ekusebenzeni kukagesi ukuhlukanisa, ihlukaniswe yaba i-6G ne-12G, i-SAS4.0 24G, kodwa inqubo yokukhiqiza evamile iyafana, namuhla sizokwabelana, isingeniso se-Mini SAS esingenalutho kanye nemingcele yokulawula inqubo yokukhiqiza. .Kulayini wamafrikhwensi aphezulu we-SAS, i-impedance, attenuation, loop loss, crosswish nezinye izinkomba zokudlulisa yizona ezibaluleke kakhulu, futhi i-SAS high frequency working frequency working ngokuvamile ingu-2.5GHz noma ngaphezulu ngaphansi kwefrikhwensi ephezulu, ake sibheke ukuthi ukhiqizwa kanjani ulayini wejubane eliphezulu SAS.
Incazelo yesakhiwo sekhebula le-SAS
Ukulahlekelwa okuphansi kukhebula lokuxhumana elivamise ukwenziwa nge-polyethylene enegwebu noma i-polypropylene enegwebu njengezinto zokufakelwa, i-conductor emibili evalekile enocingo oluphansi (imakethe futhi inomkhiqizi USEBENZISA izindlela ezimbili) ezindizeni eziqashiwe, ngaphandle kwekhondakta evalekile kanye nomhlabathi. i-wire winding kanye ne-aluminium foil kanye nebhande le-polyester lamination, ukwakhiwa kwenqubo yokufakelwa kanye nokulawulwa kwenqubo, ukwakheka kanye nezidingo zokusebenza zikagesi zokudluliswa kwesivinini esikhulu kanye nethiyori yokudlulisa.
Izidingo zama-conductor
Ku-SAS, okuyilayini yokudlulisa imvamisa ephezulu, ukufana kwesakhiwo kwengxenye ngayinye kuyisici esibalulekile sokunquma imvamisa yokudlulisela yekhebula.Ngakho-ke, njengomqhubi we-high frequency transmission line, indawo engaphezulu iyindilinga futhi ibushelelezi, futhi isakhiwo sangaphakathi sokuhlelwa kwe-lattice sifana futhi sizinzile, ukuqinisekisa ukufana kokusebenza kukagesi endaweni yobude;Umqhubi kufanele futhi abe nokumelana okuphansi kwe-DC;Ngesikhathi esifanayo kufanele kugwenywe ngenxa yezintambo, okokusebenza, noma enye idivayisi egoba i-conductor yangaphakathi ngezikhathi ezithile noma ngezikhathi ezithile, ukuwohloka nokulimala, njll., emigqeni yokudlulisa imvamisa ephezulu, ukumelana kukakhonda kubangelwa ukuncishiswa kwekhebula (isisekelo samapharamitha aphezulu). iphepha 01 - attenuation) ezicini eziyinhloko, kunezindlela ezimbili zokunciphisa ukuphikiswa komqhubi: kwandisa ububanzi bomqhubi, khetha impahla yomqhubi nge-resistivity ephansi.Lapho i-diameter ye-conductor inyuswa, ukuze kuhlangatshezwane nezidingo ze-impedance yesici, ububanzi bangaphandle bokufakwa kwe-insulation kanye nomkhiqizo oqediwe kufanele kwandiswe ngokufanele, okuholela ekwenyukeni kwezindleko kanye nokucubungula okungalungile.Ngokuvamile esetshenziswa resistivity ongaphakeme izinto conductive for isiliva, ngokombono, USEBENZISA umqhubi wesiliva, ububanzi bomkhiqizo ophelile kuzonciphisa, kuzoba nokusebenza okuhle kakhulu, kodwa ngenxa yokuthi intengo yesiliva iphakeme kakhulu kunentengo yethusi, izindleko ziphezulu kakhulu, ayikwazi ukukhiqiza, ukuze sikwazi ukucabangela intengo kanye nokumelana okuphansi, sasebenzisa umphumela wesikhumba, ukuklama umqhubi wekhebula, Njengamanje, i-SAS 6G isebenzisa umqhubi wethusi oqoshiwe ukuze ihlangabezane nokusebenza kukagesi, kuyilapho i-SAS 12G futhi i-24G iqala ukusebenzisa i-conductor ene-silver-plated.
Uma kukhona inkambu yamanje eshintshanayo noma eshintshanayo kagesi ku-conductor, okwenzekayo kokusatshalaliswa kwamanje okungalingani kuzokwenzeka ku-conductor.Njengoba ibanga elisuka ebusweni bomqhubi likhuphuka, ukuminyana kwamanje ku-conductor kuncipha ngokuqhubekayo, okungukuthi, i-current in conductor igxila ebusweni bomqhubi.Kusukela ekubukeni kwesigaba esiphambanayo ngokuqondana nendawo yamanje, ukuqina kwamanje engxenyeni emaphakathi ye-conductor ngokuyisisekelo kunguziro, okungukuthi, cishe akukho ukugeleza kwamanje, kuphela engxenyeni yonqenqema lomqhubi kuzoba ne-sub. -geleza.Ngamagama alula, i-current igxile engxenyeni "yesikhumba" ye-conductor, ngakho-ke ibizwa ngokuthi umphumela wesikhumba futhi umphumela ubangelwa ukushintshwa kwenkambu ye-electromagnetic eyenza inkambu kagesi ye-vortex ngaphakathi kwe-conductor, ekhansela i-current yasekuqaleni. .Umphumela wesikhumba wenza ukumelana komqhubi kukhuphuke nemvamisa yokwenyuka kwamanje okushintshashintshayo, futhi kuholela ekwehleni kokusebenza kahle kwamanje kokudluliswa kwentambo, sebenzisa izinsiza zensimbi, kepha ekwakhiweni kwekhebula lokuxhumana lemvamisa ephezulu, kepha kungathatha ithuba lalokhu. isimiso, ngendlela yokunamathisela isiliva ebusweni ukuze kuhlangatshezwane nezidingo ezifanayo zokusebenza ngaphansi kwesisekelo sokunciphisa ukusetshenziswa kwensimbi, ngaleyo ndlela kunciphise izindleko.
Izidingo ze-insulation
I-insulation medium kufanele ibe iyunifomu, efana naleyo ye-conductor.Ukuze uthole i-dielectric engaguquki ephansi ye-S kanye ne-tangent ye-Dielectric loss Angle, izintambo ze-SAS zivame ukufakwa i-PP noma i-FEP, kanti ezinye izintambo ze-SAS nazo zifakwe igwebu.Lapho idigri yogwebu ingaphezu kuka-45%, kunzima ukuyithola igwebu lamakhemikhali, futhi idigri yegwebu alizinzile, ngakho-ke ikhebula elingaphezu kuka-12G kufanele libe namagwebu angokomzimba.
Umsebenzi oyinhloko we-endodermis enamagwebu engokomzimba ukukhulisa ukunamathela phakathi kwe-conductor kanye ne-insulation.Ukunamathela okuthile kufanele kuqinisekiswe phakathi kongqimba lwe-insulating kanye nomqhubi;uma kungenjalo, igebe lomoya lizokwakhiwa phakathi kwesendlalelo se-insulating kanye ne-conductor, okuholela ekushintsheni kwe-dielectric constant £ kanye nevelu ye-tangent ye-Angle yokulahlekelwa kwe-dielectric.
I-polyethylene insulation material idluliselwa ekhaleni ngesikulufu, futhi kungazelelwe kuvezwe ukucindezela komkhathi lapho kuphuma khona ikhala, kwakheka izimbobo namabhamuza axhumayo.Ngenxa yalokho, igesi ikhishwa esikhaleni phakathi komqhubi kanye nokuvuleka kokufa, okwenza imbobo ye-bubble ende ebusweni bomqhubi.Ukuze uxazulule lezi zinkinga ezimbili ezingenhla, kuyadingeka ukukhipha ungqimba lwegwebu ngesikhathi esifanayo... Isikhumba esincanyana sicindezelwa ungqimba lwangaphakathi ukuze kuvinjelwe ukukhishwa kwegesi ebusweni bomqhubi, futhi ungqimba lwangaphakathi lungavala amabhamuza. ukuze kuqinisekiswe ukuzinza okufanayo kwendawo yokudlulisela, ukuze kuncishiswe ukubambezeleka nokubambezeleka kwekhebula, nokuqinisekisa ukuthikamezeka kwesici esizinzile kuwo wonke ulayini wokudlulisela.Ukuze kukhethwe i-endodermis, kufanele ihlangabezane nezidingo ze-extrusion yodonga oluncane ngaphansi kwezimo zokukhiqiza ngesivinini esikhulu, okungukuthi, izinto ezibonakalayo kufanele zibe nezakhiwo ezinhle kakhulu zokudonsa.I-LLDPE iyisinqumo esingcono kakhulu sokuhlangabezana nale mfuneko.
Izidingo zezisetshenziswa
I-insulated core wire iyisisekelo sokukhiqizwa kwekhebula, futhi ikhwalithi yocingo oluyinhloko inethonya elibaluleke kakhulu kwinqubo elandelayo.Enqubweni yokwamukela i-core wire, okokusebenza kokukhiqiza kuyadingeka ukuthi kube nomsebenzi wokuqapha nokulawula ku-inthanethi ukuze kuqinisekiswe ukufana nokuzinza kwentambo ewumgogodla, kanye nemingcele yenqubo yokulawula, okuhlanganisa ububanzi bocingo oluwumgogodla, amandla emanzini, ukugxila, njll.
Ngaphambi kokuhlukanisa izintambo, kuyadingeka ukushisa ibhande le-polyester elizinamathelayo ukuze lincibilike futhi libophe ingcina encibilikayo eshisayo ebhandeni le-polyester elizinamathelayo.Ingxenye encibilikayo eshisayo yamukela izinga lokushisa elilawulekayo le-electromagnetic heatheater preheater, elingalungisa izinga lokushisa lokushisa ngokufanele ngokuya ngezidingo zangempela.Kunezindlela zokufaka eziqondile nezivundlile ze-preheater evamile.I-preheater eqondile ingasindisa isikhala, kodwa intambo ejikajikayo idinga ukudlula amasondo amaningi alawulayo anama-engeli amakhulu ukuze ingene ku-preheater, okulula ukuguqula indawo ehlobene ye-insulating core wire kanye nebhande lokugoqa, okuholela ekwehleni kwe-preheater. ukusebenza kukagesi kolayini wokudlulisa imvamisa ephezulu.Ngokuphambene, i-preheater evundlile ikumugqa ofanayo nepheya yomugqa wokugoqa, ngaphambi kokungena ku-preheater, ipheya yomugqa idlula kuphela amasondo ambalwa alawulayo anendima yokuqondanisa kazwelonke, ukunitha komugqa wokugoqa akuguquli i-Angle lapho udlula. ngokusebenzisa isondo elilawulayo, ukuqinisekisa ukuzinza kwesigaba sokuluka isikhundla se-insulating core wire kanye nebhande lokugoqa.Okuwukuphela kokubi kwe-preheater evundlile ukuthi ithatha isikhala esiningi futhi ulayini wokukhiqiza mude kunomshini osongwayo one-preheater eqondile.
