Ungasho Kanjani Uma Ikhebula Le-Coax Lingalungile (Umhlahlandlela Wezindlela Ezi-2)
Okuqukethwe
Kulesi sihloko, ngizokufundisa ukuthi ungayibona kanjani ikhebula le-coax elibi ngemizuzu embalwa nje.
Njengo-jack-of-all-trades onolwazi, ngisebenzisa amaqhinga amaningana ukuhlola isimo sezintambo ze-coax. Ngizokufundisa okuhle kakhulu kulo mhlahlandlela. Izintambo ezilimele ze-coaxial ziza nezinkinga eziningi, ezihlanganisa kodwa ezingagcini nje ngamasiginali abethelwe noma ukwamukela kabi i-inthanethi. Ukuthola umnyombo kubalulekile, hhayi nje imibono yokwenza izinqumo.
Ngokuvamile, udinga ukulandela izinyathelo ezimbalwa ezilula zokuxilonga ukuthi ikhebula le-coax lilungile yini:
- Xhuma i-DSS01 coax cable tester kusokhethi i-coax bese ucindezela inkinobho ukuze uyihlole.
- Yenza ukuhlolwa kokuqhubeka nge-multimeter ye-electronic.
- Ungahlola futhi amandla, ukumelana, kanye ne-impedance nge-multimeter ye-electronic.
Ngizokutshela okwengeziwe ngezansi.
Indlela Yokuhlonza Ikhebula Le-Coax Elingalungile
Kubaluleke kakhulu ukusungula isimo sentambo yakho ye-coaxial. Lokhu kuzokusiza ukuthi ubone inkinga yangempela futhi ungaqageli. Ungasebenzisa izindlela ezimbalwa ukuhlola ukuthi ikhebula lakho le-coax lihle noma libi. Ngizongena ngemininingwane mayelana namanye alawa masu.
Indlela 1: Ukusebenzisa i-multimeter
Ungasebenzisa i-multimeter ukuhlola ukuthi ikhebula lakho le-coax alilungile yini.
I-multimeter ihlola amakhono ezingxenye ezihlukahlukene zensiza kagesi ngezibalo eziningi eziyinkimbinkimbi.
Yenza izivivinyo ezilandelayo kukhebuli ye-coax:
Ukuhlolwa kokuqhubeka
Izinyathelo ezilandelayo zizokusiza:
Isinyathelo 1: Faka i-multimeter
Faka i-probe lead lead kujekhi eno-V eduze kwayo bese kuthi i-probe emnyama ihole kujeke we-COM.
Bese usetha i-multimeter enanini lepharamitha ethi "Ohm" ngokuzungezisa ukudayela kwesikhethi. Ekugcineni, ping izintambo zokuhlola; uma i-multimeter ikhala, kukhona ukuqhubeka phakathi kwama-probes. Manje ake siqale ukuhlola intambo ye-coaxial.
Isinyathelo sesi-2: Hlola izixhumi
Ikhebula le-coaxial alinayo i-polarity.
Thinta izintambo ze-probe kuzixhumi ezimbili zekhebula le-coaxial. Uma i-multimeter ikhala futhi ifundeka ngaphansi kuka-1 ohm, khona-ke kukhona ukuqhubeka kukhebuli yakho ye-coax. Uma ukufunda kudlula i-ohm eyodwa, izixhumi zakho zinephutha.
Isinyathelo sesi-3: Hlola izintambo ngaphakathi kwezixhumi.
Thinta izikhonkwane ngaphakathi kwezixhumi ezimbili futhi. Noma yikuphi ukufunda ngaphansi kwe-ohm eyodwa kusho ukuthi i-coax yakho yinhle.
Isivivinyo sokumelana
Lapha, i-multimeter ye-electronic izohlola i-voltage yesihlangu sekhebula le-coaxial nezinye izingxenye zekhebula. Isibonisi sizobonisa izimpendulo/ukufundwa ku-HMS (ama-hectometer).
Isinyathelo 1. Setha i-multimeter yakho kumodi yokumelana
Isinyathelo 2. Faka i-50 ohm dummy load kujeke owodwa. Bese uthinta umthofu owodwa we-probe ebusweni kwesinye isixhumi bese omunye uholela ngaphakathi kwesokhethi efanayo—awukho umthwalo we-dummy.
Isinyathelo 3. Qhathanisa imiphumela yakho yokumelana ne-impedance ye-coax yakho.
Ukuhlolwa kwamandla
Futhi, sebenzisa i-multimeter ye-elekthronikhi ukuze uhlole amandla ejazi kanye nomqhubi wekhebula le-coax. Izibalo zizoba ngama-picofarads (pf).
Inqubo: Uma i-multimeter ishintshelwe kumodi yokulinganisa ukumelana, thinta umkhondo kuzo zombili iziphetho zentambo ye-coaxial futhi uqaphele ukufundwa, okuzoba kuncane kakhulu - kuma-picometer.
Ukuhlolwa kwe-Inductance
Ungasebenzisa i-multimeter ye-electronic ukuhlola i-inductance yesihlangu kanye nomugqa wekhebula le-coaxial. Lapho kuhlolwa i-inductance, kuxoxwa ngezixazululo ze-nanohenry (NH) ne-ohm (ohm).
Izimpawu zentambo ye-coaxial eyonakele
Izixhumi ze-Rustic - Uma ukugqwala kuvela emaphethelweni ekhebula lakho le-coax, ikhebula le-coax cishe alinasici.
Izingxenye ezingekho zibonisa inkinga ngentambo ye-coax.
Umbala oluhlaza wezixhumi zekhebula le-coaxial nawo ubonisa umonakalo.
Izixhumi ezibuthakathaka – Uma usonta izixhumi kukhebula eliqinile futhi uzizwe sengathi zikhululekile, zilimele.
izintambo eziveziwe - Uma izintambo ezingaphakathi kwekhebula le-coax zibonakala, zonakele.
Ishubhu lepulasitiki elilimele (elibizwa nangokuthi isihlangu serabha) - Uma isihlangu senjoloba sonakalisiwe, ikhebula lakho le-coax lingase libe nesici.
Ngakho-ke, uma ubona noma yiziphi zalezi zimpawu, sebenzisa i-multimeter ye-electronic ukuze uqinisekise.
Qaphela: Indlela yokuqala yokuthola yokuhlola i-coax ukubona ukuthi asehlulekile yini.
Izintambo ze-coaxial zenziwa yizinkampani eziningi ezihlukahlukene, ngakho izinga labo liyahlukahluka kakhulu.
Indlela yesi-2: Ukusebenzisa i-DSS01 Coax Cable Tester
Ngincoma ukusebenzisa i-DSS01 Coax Cable Tester ukuze uhlole izinkinga ngentambo yakho ye-coax. Ngalesi sisetshenziswa, ugwema ukuthenga noma ukusebenzisa okulandelayo:
- Ukwamukela isignali yokuxazulula inkinga
- Ukuxazulula inkinga ukudluliswa kwesignali
- Ayikho i-multimeter edingekayo
- I-Coax Cable Tracking
- Ukuhlolwa kokuqhubeka - kukhebula le-coaxial.
- Okudingayo i-DSS01 Coax Cable Tester!
Isetshenziswa kanjani i-DSS01 coaxial cable tester
Landela lezi zinyathelo ezilula ukuze uhlole ikhebuli yakho ye-coax ngesihloli se-DSS01:
Isinyathelo 1. Xhuma i-DSS01 Coax Cable Tester kusokhethi se-coax.
Isinyathelo 2. Chofoza inkinobho ethi Hlola. Imiphumela izovela emizuzwaneni embalwa.
Isihloli sekhebula coaxial se-DSS01 songa isikhathi nemali. Konke okudingeka ukwazi ukuthi ungaxhuma kanjani isokhethi ye-coaxial kanye nenkinobho yokuhlola - kulula ukuyisebenzisa.
Izinkinga Ezivamile Ezithinta Amakhebuli Ama-Coaxial
Ngikhethe izimbangela ezine eziyinhloko zokuhluleka kwekhebula le-coaxial. Zigweme ukuze uqinisekise impilo ende kanye nokuphepha kukonke kwezintambo zakho ze-coax.
Ukulimala okushisayo
Indawo encibilikayo yamakhebuli angama-coaxial ngu-150°F. Leli iphoyinti lokuncibilika eliphansi uma kuqhathaniswa. Ngakho-ke, izintambo ze-coaxial zisengozini yokushisa okuphezulu. (1)
Amacebo: Ukuze ugweme ukulimala kokushisa kukhebuli ye-coaxial, igcine ikude nemithombo yokushisa. Uma ungenjalo, isihlangu senjoloba singase sincibilike, siphushe izakhi (kwikhebula) endaweni.
Ukulimala kwamanzi
Imishini eminingi kagesi isengozini yamanzi. Amakhebuli angama-coaxial awahlukile. Izintambo zikagesi nezingxenye zingase zehluleke uma zivezwe emanzini. Ngakho-ke, gcina intambo ye-coaxial ikude namanzi.
ukuhlanekezela ngokomzimba
Isikrini sentambo ye-coaxial sintekenteke. Umgodla othambile wekhebula ungaphuka uma ujikijelwa, uphathwa kabi, noma ugotshwe ngokunganaki. Njalo hambisa izintambo ngqo phambili. Ukugoba okuncane noma i-kink kungabangela ukuthi izingaphakathi zekhebula le-coax (noma izingxenye zangaphakathi) ziwe.
Ukulimala kwesixhumi
Isixhumi esilimele singaholela ekuhlulekeni kwentambo ye-coaxial.
Izintambo zifakwe izixhumi emikhawulweni yomibili. Izixhumi zidlulisela ulwazi kusuka komunye umthombo kuya komunye. Ngakho-ke, ukushintsha esinye sezixhumi ezimbili kwehlisa umsebenzi wekhebula eliqinile. Ngenhlanhla, uma uthola izinkinga, ungashintsha izixhumi esikhundleni sokuthenga ikhebula elisha. Futhi, yiqiniso, lesi yisizathu esiyinhloko sokuhluleka kwezintambo ze-coaxial. (2)
