[AipuWaton] Ivikelwe vs Ikhebula Lezikhali

Zenzani izintambo ezingu-8 kukhebula ye-Ethernet

Uma kuziwa ekukhetheni ikhebula elifanele lezidingo zakho ezithile, ukuqonda umehluko phakathi kwezintambo zesihlangu nezikhali kungaba nomthelela omkhulu ekusebenzeni kukonke nokuqina kokufaka kwakho. Zombili lezi zinhlobo zihlinzeka ngokuvikela okuyingqayizivele kodwa zibhekelela izidingo nezindawo ezihlukene. Lapha, sihlukanisa izici ezibalulekile zezintambo zesihlangu nezikhali, sikusize wenze isinqumo unolwazi.

Ayini ama-Shield Cables?

Izintambo zeShield ziklanyelwe ngokukhethekile ukuvikela ekuphazamisekeni kwe-electromagnetic (EMI), okungaphazamisa ubuqotho besignali. Lokhu kugxambukela kuvame ukuvela ezintweni zikagesi eziseduze, amasignali omsakazo, noma amalambu e-fluorescent, okwenza ukuvikela kubaluleke kakhulu ekugcineni ukuxhumana okucacile ezintweni zikagesi.

Izici Eziyinhloko Zezintambo Zesihlangu:

Ngokusebenzisa lezi zendlalelo ezivikelayo, izintambo ezivikelayo ziqinisekisa ukuthi amasiginali ahlala eqinile futhi ukuphazamiseka okuvela emithonjeni yangaphandle kuyancishiswa.

Ukwakhiwa Kwezinto:

Ukuvikela ngokuvamile kwenziwa kusukela ku-foil noma imicu yensimbi ephothiwe njengethusi elithakiwe, i-aluminium, noma ithusi elingenalutho.

Izicelo:

Ngokuvamile kutholakala ezintanjeni zenethiwekhi, izintambo zomsindo, nemigqa yedatha lapho ukugcinwa kwekhwalithi yesignali kubalulekile.

Ukuvikelwa Okunikezwayo:

Isebenza kahle ekuvimbeni ukuphazamiseka okungafuneki ngenkathi ivumela isignali ukuthi idlulise ngokucacile nangempumelelo.

Yiziphi Izintambo Zezikhali?

Ngokuphambene, izintambo zempi zenzelwe ukuhlinzeka ngokuvikeleka ngokomzimba kunokuba zivikeleke ngogesi. Asetshenziswa kakhulu ezindaweni lapho ingozi yokulimala kwemishini idlangile, njengaseziteshini ezincane, amaphaneli kagesi, neziteshi ze-transformer.

Izici Eziyinhloko Zezintambo Zezikhali:

Izintambo zezikhali ziqinisekisa ubuqotho bezingxenye zikagesi ngaphakathi, zivikela ezingozini ezingase ziphazamise ukusebenza.

Ukwakhiwa Kwezinto:

Izikhali zivame ukwakhiwa ngensimbi noma i-aluminium, yakhe ungqimba lwangaphandle oluqinile eduze kwekhebula.

Izicelo:

Ilungele ukusetshenziswa ezimeni ezinzima lapho izintambo zingase zichayeke kumandla acindezelayo, imithelela, noma okunye ukucindezeleka komshini.

Ukuvikelwa Okunikezwayo:

Ngenkathi zinikeza ukuhlukaniswa okuthile kumsindo kagesi, umsebenzi oyinhloko ukuvimbela ukulimala ngokomzimba kumakhondaktha angaphakathi.

Kufanele Usebenzise Nini Ukuvikela noma Izikhali (noma Zombili)

Ukunquma ukuthi ikhebula lidinga isivikelo, izikhali, noma kokubili kuncike ezintweni ezimbalwa:

Ukusetshenziswa okuhlosiwe:

 · Ukuvikela:Uma ikhebula lizosetshenziswa endaweni esengozini yokuphazamiseka kazibuthe kagesi (njengezilungiselelo zemboni noma eduze kwama-transmitters omsakazo), ukuvikela kubalulekile.
· Izikhali:Amakhebuli asezindaweni ezinethrafikhi ephezulu, achayeke engcupheni yokuchotshozwa noma ukuhuzuka, kufanele ahlanganise nezikhali ukuze zivikeleke kakhulu.

Izimo Zemvelo:

· Amakhebuli Avikelekile:Kuhle kakhulu kuzilungiselelo lapho i-EMI ingabangela izinkinga zokusebenza, kungakhathaliseki izinsongo zomzimba.
· Amakhebuli Ahlomile:Ilungele izindawo ezinokhahlo, ukufakwa kwangaphandle, noma izindawo ezinemishini esindayo lapho ukulimala komshini kukhathaza khona.

Ukucatshangelwa kwesabelomali:

· Izindleko:Amakhebuli okungezona ezezikhali ngokuvamile eza nenani eliphansi lethegi ngaphambili, kuyilapho ukuvikelwa okwengeziwe kwamakhebuli ahlomile kungase kudinge ukutshalwa kwezimali okuphezulu ekuqaleni. Kubalulekile ukukala lokhu ngezindleko ezingaba khona zokulungisa noma ukushintshwa kwezimo eziyingozi kakhulu.

Izidingo zokuvumelana nezimo nokufakwa:

· Ivikelwe vs. Okungavikelwe:Izintambo ezingavikelwe zivame ukunikeza ukuguquguquka okukhulu ezikhaleni eziqinile noma ukugoba okucijile, kuyilapho amakhebuli ahlomile angase aqine kakhulu ngenxa yezendlalelo zawo ezivikelayo.

Isiphetho

Kafushane, ukuqonda umehluko phakathi kwezintambo zesihlangu nezikhali kubalulekile ekukhetheni umkhiqizo ofanele wephrojekthi yakho. Izintambo ezivikelayo zihamba kahle kakhulu ezindaweni lapho ukuwohloka kwesignali evela ekuphazanyisweni kozibuthe kagesi kuyinto ekhathazayo, kuyilapho izintambo zempi zinikeza ukuqina okudingekayo ukuze zimelane nokulimala ngokomzimba ezilungiselelweni eziyinselele.
