[Aipuwaton] ikhebula eliphansi le-voltage: izinhlobo nencazelo

Yini izintambo eziyi-8 kukhebula le-Ethernet

Ukuqalisa

Esikhathini sendawo yesimanje kagesi kagesi, izintambo eziphansi zamandla kagesi ziyizakhi ezibalulekile eziqinisekisa ukudluliselwa kwamandla okuphephile. Ukuqonda izinhlobo ezahlukahlukene zezintambo eziphansi ze-voltage, izici zazo, kanye nezicelo zibalulekile kunoma ngubani obandakanyeka ekufakweni kukagesi noma ukuthuthukiswa. Le bhulogi izonikeza ukubuka konke okuphelele kwezintambo eziphansi ze-voltage, kufaka phakathi izincazelo zazo, izinhlobo, kanye nemikhuba emihle yokukhethwa.

Yiziphi izintambo eziphansi ze-voltage?

Amakhekhe aphansi ama-voltage yizintambo zikagesi ezenzelwe ukusebenza kuma-voltages aphansi ama-volts aphansi, ngokuvamile angaphansi kwe-1 000 volts ac noma i-1,500 Volts DC. Lezi zintambo zisetshenziselwa ukwenza amasistimu kagesi adinga amandla amancane futhi ajwayele ukusetshenziswa ekuxhumaneni ngocingo, ukuhanjiswa kwedatha, kanye nezixazululo ezahlukahlukene zokuphepha kanye nezixazululo ezahlukahlukene. Izinzuzo zezinsimbi eziphansi zamandla kagesi zifaka ukuphepha okuthuthukile, ingozi encishisiwe yokushaqeka kukagesi, nokusebenza kwamandla.

Izinhlobo zezintambo eziphansi zeVoltage

Izintambo zegesi eziphansi ziza ngezinhlobo ezahlukahlukene, ngamunye afanelekele izinhlelo ezithile. Nazi ezinye zezinhlobo ezivame kakhulu:

Lawula izintambo

Izintambo zokulawula zenzelwe ukuxhumanisa ukukala kanye namadivayisi okulawula ezinhlelweni ezenzakalelayo. Ngokuvamile zifaka izici ezinjengokuvikela ukuvikela ekuphazanyisweni kwe-electromagnetic (EMI) futhi zisetshenziswa ezindaweni zezimboni zokulawula imishini nokuqapha.

Izintambo Zokuxhumana

Lezi zintambo zibalulekile ekudluliseleni ngedatha ekuxhumaneni ngocingo nasekunethiwekhi. Izibonelo zifaka izintambo ezimbili ezisontekile (isib. Cat 5e, ikati 6) nezintambo ze-coaxial, ezidlulisela amasiginali amabanga amade ngenkathi egcina ubuqotho besiginali.

Amakhabethe

Izintambo zamandla kagesi eziphansi ziletha ugesi kuhlu lwamadivayisi nezinhlelo, kusuka ekufakweni kokukhanyisa kuzinhlelo zokuphepha. Beza ngokucushwa okuhlukahlukene, kufaka phakathi izintambo eziningi nezingalo, kuya ngezidingo zamandla nomthwalo kagesi.

Izintambo ze-COAXIAL

Isetshenziswa kaningi kuzinhlelo zokusebenza zevidiyo neyama-aladi, izintambo ze-coaxial zenzelwe ukudlulisa amasiginali afudumele aphezulu ngokulahleka okuncane. Zivame ukuqashwa ezinhlelweni zokubhekwa, ithelevishini ye-Cable, kanye nama-Intanethi.

Izintambo ze-Fibre Optic

Yize kungenziwa kuhlukaniswe ngokuqinile njengezintambo ze-voltage eziphansi, izintambo ze-fiber optic zivumela ukudluliswa kwedatha ephezulu ngezimpawu zokukhanya. Baqashelwa kwizicelo zokuxhumana ezifuna i-bandwidth ephezulu ngamabanga amade.

Izintambo eziguquguqukayo

Izintambo eziguquguqukayo zenzelwe imishini ephathekayo, zinikeza ukuqina okukhulu nokumelana nokugoba. Lezi zintambo zivame ukusetshenziswa ekufakweni kwesikhashana, ukukhanyisa kwesiteji, nokuxhunyaniswa kwamathuluzi.

Ukukhetha ikhebula le-voltage eliphansi elifanele

Lapho ukhetha amakhekhe aphansi we-voltage isicelo, cabanga ngalezi zinto ezilandelayo:

Isilinganiso seVoltage

Qinisekisa ukuthi isilinganiso se-voltage ka-Cable sihambisana nezidingo zohlelo lokusebenza.

Umthamo wamanje wokuthwala

Hlola umthwalo odingekayo wokuthi ukhethe ikhebula ngegeji elifanele nokwakha.

Izimo zezemvelo

Hlola ukuthi ngabe ikhebula lizosetshenziswa ngaphakathi ngaphakathi noma ngaphandle bese likhetha izinto zokufaka ezinikezela ukumelana nomswakama, imisebe ye-UV, noma ukuguquguquka kwezinga lokushisa.

Ukuhambisana nokulawula

Qinisekisa ikhebula elikhethiwe lihlangabezana namazinga afanele ezokuphepha kanye nemithetho yendawo.

Bheka ukulimala

Ngaphambi kokufaka, hlola ngokuphelele zonke izintambo zomonakalo, uqinisekise ukuthi ziqondanisa imininingwane echazwe ezinhlelweni zakho zephrojekthi.

Ukugcina

Izintambo zeVoltage eziphansi zihlanganiswa ekusebenzeni okuphephile nokusebenzayo kwezinhlelo zanamuhla zikagesi. Ngokuqonda izinhlobo nezincazelo zezintambo eziphansi ze-voltage, ungenza izinqumo ezinolwazi ezithuthukisa ukusebenza nokuphepha kokufakwa kwakho kukagesi. Noma ngabe usebenza ngephrojekthi entsha noma uthuthukise izinhlelo ezikhona, ikhebula le-voltage eliphansi lingenza wonke umehluko.
