Tusmo
Maqaalkan, waxaan ku bari doonaa sida loo aqoonsado fiilada coax ee xun dhowr daqiiqo gudahood.
Sida khibrad-jack-of-all-trades, waxaan isticmaalaa dhowr farsamooyin si aan u hubiyo xaaladda fiilooyinka coax. Waxaan ku bari doonaa waxa ugu fiican ee hagahan. Fiilooyinka coaxial ee dhaawacan waxay la yimaadaan dhibaatooyin badan, oo ay ku jiraan laakiin aan ku xaddidnayn calaamadaha sir ah ama soo-dhoweynta internetka oo liita. Helitaanka sababta asalka ah waa muhiim, ma aha oo kaliya malo-awaalka go'aannada.
Guud ahaan, waxaad u baahan tahay inaad raacdo dhowr tillaabo oo fudud si aad u ogaatid haddii fiilada coax ay wanaagsan tahay:
- Ku xidh tijaabada fiilada coax DSS01 godka coax oo taabo badhanka si aad u tijaabiso.
- Ku samee tijaabada sii wadida multimeter elegtroonig ah.
- Waxa kale oo aad ku hubin kartaa awoodda, iska caabinta, iyo xannibaadda adigoo isticmaalaya multimeter elegtroonig ah.

Sida Loo Ogaado Ciladaha Coax Cable
Aad bay muhiim u tahay inaad dejiso xaaladda fiiladaada coaxial. Tani waxay kaa caawin doontaa inaad ogaato dhibaatada dhabta ah oo aadan qiyaasi karin. Waxaad isticmaali kartaa dhowr habab si aad u hubiso in xadhigga coax uu fiican yahay ama uu xun yahay. Waxaan si faahfaahsan uga hadli doonaa qaar ka mid ah farsamooyinkan.
Habka 1: Isticmaalka multimeter ah
Waxaad isticmaali kartaa multimeter-ka si aad u hubiso in xadhigga coax uu xun yahay.
Multimeter-ku wuxuu tijaabiyaa awoodaha qaybaha kala duwan ee qalabka elegtarooniga ah iyadoo loo marayo xisaabin badan oo adag.
Ku samee tijaabooyinkan soo socda fiilada coax:
Imtixaanka sii wadista
Tallaabooyinka soo socda ayaa ku caawin doona:
Tallaabada 1: Ku rakib multimeter-ka
Geli sunta rasaasta cas ee jaakka oo V ku xiga ka dibna baaraha madow uu hogaamiyo jaakadda COM.
Kadibna multimeterka dhig qiimaha halbeegga "Ohm" adiga oo u rogaya garaaca doorashada. Ugu dambeyntii, ping fiilooyinka baaritaanka; haddii multimeter-ku dhawaaqo, waxaa jira sii waditaanka u dhexeeya baarayaasha. Hadda aan bilowno tijaabinta fiilada coaxial.
Tallaabada 2: Hubi xirayaasha
Cable Coaxial ma laha polarity.
Taabo fiilooyinka baaritaanka ee labada xiriiriye ee fiilada coaxial. Haddii multimeter-ku dhawaaqo oo uu akhriyo wax ka yar 1 ohm, markaa waxaa jira sii wadista fiiladaada coax. Haddi akhrisku ka bato hal ohm, xidhidhiyayaashaadu waa khalad.
Talaabada 3: Hubi fiilooyinka gudaha isku xidhayaasha.
Taabo biinanka ku yaal gudaha labada xiriiriye mar labaad. Akhris kasta oo ka hooseeya hal ohm macnaheedu waa coax-kaagu wuu fiican yahay.
Imtixaanka iska caabinta
Halkan, multimeter-ka elektarooniga ah ayaa tijaabin doona danabka gaashaanka fiilada coaxial iyo qaybaha kale ee fiilada. Bandhigu waxa uu muujin doonaa jawaabaha/akhrinta HMS (hektometer).
talaabo 1. U deji multimeterkaaga qaabka iska caabinta
talaabo 2. Geli culays dhan 50 ohm hal jaak. Dabadeed taabo mid ka mid ah rasaasta baadhista ooga korka xidhiidhiyaha kale ka kalena hogaami gudaha gudaha isla godka-aan culeeys cakiran.
talaabo 3. Is barbar dhig natiijooyinkaaga iska caabbinta iyo cilad-xumada magaca ah ee fiiladaada coax.
Hubinta awooda
Mar labaad, isticmaal multimeter elegtroonig ah si aad u hubiso awoodda jaakada iyo kirishbooyada fiilada coax. Xisaabinta waxay ku jiri doontaa picofarads (pf).
Habka: Iyada oo multimeter-ka loo beddelay habka cabbirka caabbinta, taabo hogaanka labada daraf ee fiilada coaxial oo xusuusnow akhrinta, taas oo noqon doonta mid aad u yar - picometers.
Imtixaanka inductance
Waxaad isticmaali kartaa multimeter elegtroonig ah si aad u hubiso inductance ee gaashaanka iyo xariiqda fiilada coaxial. Marka la tijaabinayo inductance, nanohenry (NH) iyo ohm (ohm) xalalka ayaa laga wada hadlayaa.
Calaamadaha fiilada coax ee dhaawacan
Xidhiidhiyayaasha Rustic - Haddii miridhku ka soo baxo cidhifyada fiiladaada coax, fiilada coax waxay u badan tahay inay cilladaysan tahay.
Qaybaha maqan waxay muujinayaan dhibaatada ka jirta fiilada coax
Midabka cagaarka ah ee isku xirayaasha fiilooyinka coaxial ayaa sidoo kale muujinaya burbur.
Xidhiidhiyayaasha daciifka ah – Haddii aad xidhidhiyeyaasha ku maroojiso fiilada coaxial oo aad dareento inay dabacsan yihiin, way dhaawacmaan.
fiilooyinka qaawan - Haddii xargaha ku dhex jira fiilada coax ay muuqdaan, way dhaawacmaan.
Tuubbo balaastiig ah oo dhaawacan (sidoo kale loo yaqaan gaashaanka caagga ah) - Haddii gaashaanka caagga ah uu dhaawacmo, fiiladaada coax waxaa laga yaabaa inay xumaato.
Markaa, haddii aad aragto mid ka mid ah calaamadahan, isticmaal multimeter elegtaroonig ah si aad u xaqiijiso.
Fiiro gaar ah: Habka ugu horraysa ee lagu ogaan karo ee lagu baadho coax waa in la eego haddii ay hore u guuldarraysteen.
Xadhkaha Coaxial waxaa sameeya shirkado kala duwan, sidaas darteed tayadooda aad ayey u kala duwan tahay.
Habka 2: Isticmaalka DSS01 Coax Cable Tester
Waxaan kugula talinayaa inaad isticmaasho DSS01 Coax Cable Tester si aad u hubiso dhibaatooyinka fiiladaada coax. Qalabkan, waxaad ka fogaataa iibsashada ama isticmaalka waxyaabaha soo socda:
- Cilad-raadinta soo-dhoweynta calaamadaha
- Xallinta gudbinta calaamadaha
- Looma baahna multimeter
- Coax Cable Tracking
- Tijaabada joogtada ah - on cable coaxial.
- Waxa kaliya ee aad u baahan tahay waa DSS01 Coax Cable Tester!
Sida loo isticmaalo tijaabiyaha fiilada coaxial ee DSS01
Raac tillaabooyinkan fudud si aad ugu tijaabiso fiiladaada coax tijaabada DSS01:
talaabo 1. Ku xidh DSS01 Coax Cable Tester godka coax.
talaabo 2. Guji badhanka tijaabada Natiijadu waxay soo bixi doontaa dhowr ilbiriqsi gudahood.
Tijaabada fiilada coaxial ee DSS01 waxay badbaadisaa waqti iyo lacag. Waxa kaliya ee aad u baahan tahay inaad ogaato waa sida loo xiro godka coaxial iyo badhanka tijaabada - way fududahay in la isticmaalo.
Dhibaatooyinka Caadiga ah ee saameeya Xadhkaha Coaxial
Waxaan doortay afar sababood oo waaweyn oo keena cilladda fiilada coaxial. Ka fogow iyaga si aad u hubiso cimriga dheer iyo badbaadada guud ee fiilooyinkaaga coax.
Burburka kuleylka
Barta dhalaalka ee fiilooyinka coaxial waa 150 ° F. Tani waa meel dhalaalaysa oo aad u yar. Markaa, fiilooyinka coaxial waxay u nugul yihiin heerkulka sare. (1)
tilmaamo: Si aad uga fogaato in kulaylku dhaawaco xadhigga coaxial, ka fogee meelaha kulaylka. Haddii aadan samayn, gaashaanka caagga ah ayaa dhalaali kara, isaga oo ka riixaya qaybaha (ee fiilada) meesha.
Burburka biyaha
Inta badan qalabka korontada ayaa u nugul biyaha. Xadhkaha Coaxial ma aha mid ka reeban. Xadhkaha korantada iyo qaybaha ayaa laga yaabaa inay fashilmaan haddii ay biyuhu soo gaadhaan. Sidaa darteed, ka ilaali fiilada coaxial biyaha.
dhalanrog xagga jirka ah
Shaashadda fiilada coaxial waa mid jilicsan. Galka jilicsan ee fiilada ayaa jebi kara haddii la tuuro, si adag loo qabto, ama si taxadar la'aan ah loo foorarsado. Had iyo jeer toos u mari fiilooyinka. Laabashada ugu yar ama kink waxay keeni kartaa gudaha gudaha fiilada coax (ama qaybaha gudaha) inay soo baxaan.
Burburka xiriiriyaha
Xidhiidhiyaha xumaaday wuxuu u horseedi karaa inuu xumaado fiilada coaxial.
Fiilooyinka waxay ku qalabaysan yihiin isku-xirayaasha labada daraf. Xidhiidhiyayaasha ayaa xogta ka kala wareejiya ilo kale. Sidaa darteed, beddelidda mid ka mid ah labada xiriiriye waxay hoos u dhigtaa shaqada fiilada coaxial. Nasiib wanaag, haddii aad aragto dhibaatooyin, waxaad bedeli kartaa isku-xirayaasha halkii aad ka iibsan lahayd fiilo cusub. Iyo, dabcan, tani waa sababta ugu weyn ee fashilka fiilooyinka coaxial.
