SAS (Serial Yakanamatira SCSI) chizvarwa chitsva cheSCSI tekinoroji.Izvo zvakafanana neyakakurumbira Serial ATA (SATA) hard disks.Inoshandisa Serial tekinoroji kuwana yakakwira yekumhanyisa kumhanya uye kugadzirisa nzvimbo yemukati nekupfupisa tambo yekubatanidza.Kune waya isina chinhu, parizvino kunyanya kubva pakuita kwemagetsi kusiyanisa, yakakamurwa kuita 6G uye 12G, SAS4.0 24G, asi iyo mainstream kugadzirwa maitiro akafanana, nhasi tauya kuzogovana, Mini SAS isina waya yekusuma uye yekugadzira maitiro ekudzora paramita. .Kune SAS yakakwira frequency mutsara, impedance, attenuation, loop kurasikirwa, crosswish uye zvimwe zviratidzo zvekufambisa ndizvo zvakanyanya kukosha, uye SAS yakakwirira frequency mutsara wekushanda frequency inowanzo 2.5GHz kana kupfuura pasi peiyo yakakwira frequency, ngatitarisei maitiro ekugadzira a vanokwanisa high speed line SAS.
SAS cable chimiro tsananguro
Kurasikirwa kwakaderera pane yakakwirira frequency tambo yekukurukurirana inowanzo gadzirwa ne polyethylene inopupuma kana furo polypropylene semidziyo yekuisa, maviri insulated conductor ane waya yepasi (musika unewo mugadziri UNOSHANDISA nzira mbiri mbiri) munhandare dzechata, kunze kweiyo insulated conductor uye pasi. waya inomonereka uye aluminium foil uye lamination polyester bhandi, insulation process dhizaini uye maitiro ekudzora, chimiro uye magetsi ekuita zvinodiwa zvepamusoro-kumhanya kutapurirana uye kutamisa dzidziso.
Zvinodikanwa zvemakondakita
Kune SAS, inova zvakare yakakwira frequency yekufambisa mutsara, iyo dhizaini yunifomu yechikamu chimwe nechimwe chinhu chakakosha kuona iyo frequency yekufambisa kwetambo.Naizvozvo, semutyairi weiyo yakakwira frequency transmission line, iyo nzvimbo yakatenderedza uye yakatsetseka, uye iyo yemukati latice marongero chimiro chakafanana uye chakagadzikana, kuve nechokwadi chekufanana kwekuita kwemagetsi munzira yekureba;Kondakita anofanirwawo kunge aine yakaderera DC kuramba;Panguva imwecheteyo inofanirwa kudzivirirwa nekuda kwewaya, midziyo, kana imwe mudziyo wemukati conductor kukotama nguva nenguva kana aperiodic kukotama, deformation uye kukuvadzwa, nezvimwe, mumitsetse yekufambisa kwema frequency, conductor kuramba kunokonzerwa netambo attenuation (yakakwira frequency paramita base. pepa 01 - attenuation) yezvinhu zvikuru, kune nzira mbiri dzekudzikisa kondakita kuramba: inowedzera dhayamita conductor, sarudza conductor zvinhu ne low resistivity.Kana iyo conductor dhayamita yakawedzera, kuitira kuti isangane nezvinodiwa zvehunhu impedance, iyo dhayamita yekunze yekudzivirira uye chigadzirwa chakapedzwa chinofanira kuwedzerwa zvinoenderana, zvichikonzera kuwedzera mutengo uye kusagadzikana kugadzirisa.Inowanzo shandiswa yakaderera resistivity yezvinhu conductive zvesirivheri, mune dzidziso, INOSHANDISA iyo sirivheri conductor, yapera chigadzirwa dhayamita ichaderedza, ichava nekuita kukuru, asi nekuti mutengo wesirivheri wakakwira zvakanyanya kupfuura mutengo wemhangura, mutengo wakanyanya kukwirira, haigone kugadzira, kuitira kuti tikwanise kufunga nezve mutengo uye yakaderera resistivity, isu takashandisa ganda mhedzisiro, kugadzira tambo conductor, Parizvino, SAS 6G inoshandisa tinned conductor yemhangura kusangana nemagetsi, nepo SAS 12G. uye 24G inotanga kushandisa sirivheri-plated conductor.
Kana paine kuchinjika kwazvino kana kuchinjika kwemagetsi emagetsi mune conductor, chiitiko chekusaenzana kwazvino kugovera chichaitika mune conductor.Sezvo kureba kubva pamusoro pemuitisi kunowedzera, huwandu hwemazuva ano mumutungamiri hunoderera zvishoma nezvishoma, kureva kuti, ikozvino muitisi inotarisa pamusoro pemuitisi.Kubva pakuona kwechikamu chemuchinjikwa perpendicular kuenda kune yazvino, kusimba kwazvino pakati pechikamu che conductor chakanyanya zero, ndiko kuti, panenge pasina kuyerera kwazvino, chete muchikamu chemupendero weconductor unenge uine sub. -kuyerera.Mukutaura kwakapfava, yazvino yakanamirwa muchikamu che "ganda" che conductor, saka inodaidzwa kuti ganda rekuita uye mhedzisiro yacho inokonzereswa nekuchinja kwemagetsi emagetsi kunogadzira vortex yemagetsi munda mukati me conductor, iyo inodzima yepakutanga ikozvino. .Ganda rinoita kuti kuramba kweconductor kuwedzere nekuwanda kwealternating yekuwedzera ikozvino, uye zvichikonzera kudzikira kwehunyanzvi hwekufambisa kwewaya, shandisa zviwanikwa zvesimbi, asi mukugadzirwa kwetambo yepamusoro yekutaurirana, asi inogona kutora mukana weizvi. musimboti, ine nzira yekuisa sirivha pamusoro kuti isangane nekuita zvakafanana zvinodiwa pasi pechigadziro chekudzikisa kushandiswa kwesimbi, nokudaro kuderedza mutengo.
Insulation zvinodiwa
Iyo insulation medium inofanira kunge yakafanana, iyo yakafanana neyeyo conductor.Kuti uwane yakaderera dielectric inogara S uye tangent ye dielectric kurasikirwa Angle, tambo dzeSAS dzinowanzo kuvharirwa nePP kana FEP, uye dzimwe tambo dzeSAS dzinoiswawo furo.Kana iyo dhigirii yekupupa yakura kupfuura 45%, kupupa kwemakemikari kunonetsa kuwana, uye dhigirii rekupupa harina kugadzikana, saka tambo iri pamusoro pe12G inofanira kutora furo remuviri.
Basa guru reiyo foamed endodermis ndeyekuwedzera kunamatira pakati pe conductor uye insulation.Kumwe kunamatira kunofanirwa kuvimbiswa pakati peiyo insulating layer uye conductor;kana zvisina kudaro, gap remhepo richaumbwa pakati pe insulating layer uye conductor, zvichiita kuti kuchinja kwe dielectric constant £ uye tangent kukosha kwe dielectric kurasikirwa Angle.
Polyethylene insulation material inokwidziridzwa kumhino kuburikidza nescrew, uye kamwe kamwe yakafumurwa kumhepo yemhepo pakubuda kwemhino, ichigadzira maburi uye mabhubhu ekubatanidza.Nekuda kweizvozvo, gasi rinoburitswa mumukana uri pakati pe conductor uye kufa kunovhura, kuumba gomba refu rebubble pamwe nepamusoro peiyo conductor.Kuti ugadzirise matambudziko maviri ari pamusoro apa, zvinodikanwa kuburitsa furo layer panguva imwe chete… Ganda rakatetepa rinodzvanywa mukati memukati kudzivirira gasi kuburitswa pamusoro peiyo conductor, uye mukati memukati unogona kuvhara mabhuru. kuve nechokwadi kugadzikana kweiyo yunifomu yekutapurirana svikiro, kuitira kudzikisa kudzikisira uye kunonoka kwetambo, uye nekuona yakagadzikana hunhu impedance mutsetse wese wekutapurirana.Pakusarudzwa kwe endodermis, inofanirwa kusangana nezvinodiwa zvekutetepa-wall extrusion pasi pemamiriro ekugadzirwa kwepamusoro-kumhanya, kureva kuti, zvinhu zvacho zvinofanirwa kunge zvine hunhu hwakanaka.LLDPE ndiyo yakanakisa sarudzo yekuzadzisa ichi chinodiwa.
Equipment zvinodiwa
Insulated core wire ndiyo hwaro hwekugadzira tambo, uye mhando yemusimboti waya ine simba rakakosha pane rinotevera maitiro.Mukati mekutora waya wepakati, michina yekugadzira inodiwa kuve nekutarisa pamhepo uye kutonga basa kuti ive nechokwadi chekufanana uye kugadzikana kweiyo core waya, uye kutonga maitiro paramita, kusanganisira dhayamita yepakati waya, capacitance mumvura, concentricity, nezvimwe.
Pamberi pekusiyanisa wiring, zvakakosha kupisa bhandi repolyester rinozvinamira kuti rinyunguduke uye risungirire rinopisa rinonyunguduka rinonamira pabhandi re-self-adhesive polyester.Iyo inopisa inonyunguduka chikamu inotora inodzoreka tembiricha yemagetsi inodziya preheater, iyo inogona kugadzirisa tembiricha yekudziya zvakakodzera zvinoenderana nezvinodiwa chaizvo.Kune dzakamira uye dzakachinjika yekuisa nzira dzeiyo general preheater.Iyo vertical preheater inogona kuchengetedza nzvimbo, asi waya inomonereka inoda kupfuura nepakati akawanda ekudzora mavhiri ane makona mahombe kuti apinde mu preheater, zviri nyore kushandura chinzvimbo cheiyo insulating musimboti waya uye bhandi rekuputira, zvichikonzera kuderera kweiyo. kushanda kwemagetsi kwepamusoro-frequency transmission line.Mukupesana, horizontal preheater iri mumutsetse wakafanana nepeya yekuputira mutsara, usati wapinda mu preheater, iyo mutsara peya inongopfuura nepakati pemavhiri mashoma ekudzora ane basa rekurongeka kwenyika, iyo yekuputira mutsara yekuruka haishandure Angle kana ichipfuura. kuburikidza nevhiri rekutonga, kuve nechokwadi kugadzikana kwechikamu chekuruka chinzvimbo cheiyo insulating musimboti waya uye yekuputira bhandi.Izvo chete zvakashata zveyakachinjika preheater ndeyekuti inotora nzvimbo yakawanda uye mutsara wekugadzira wakareba kupfuura muchina unomonereka une vertical preheater.
