Izintambo eziphakeme zamandla kagesi

Emkhakheni wezobunjiniyela kagesi, ukukhethwa kwamakhekhe aphezulu kanye nama-voltage amakhekhe kubalulekile ukuqinisekisa ukuhanjiswa kwamandla okuphephile, okusebenzayo nokuthembekile. Ukuqonda umehluko osemqoka phakathi kwalezi zinto ezimbili zezintambo kungasiza onjiniyela, abasebenza ngogesi, nabaphathi bephrojekthi benze izinqumo ezinolwazi ngezinhlelo zabo ezithile.

Ukuchazwa kanye nobubanzi be-voltage

Izintambo eziphakeme ze-voltageyakhelwe ukuthwala kwamanje kuma-voltages ngokuvamile ngaphezulu kwama-1,000 volts (1 kv). Lezi zintambo zibalulekile ekudluliseleni ugesi kumabanga amade, njengokusuka ezitshalweni zamandla kuya kwezingane noma phakathi kokufakwa esikhundleni kanye namanethiwekhi okusabalalisa. Izicelo ezijwayelekile zifaka phakathi imigqa yamandla aphezulu nezinhlelo zokuhambisa ezingaphansi komhlaba.

Amakhebula aphansi anamandla, ngakolunye uhlangothi, asebenze kuma-voltages angaphansi kwama-1,000 volts. Zivame ukusetshenziswa ekukhanyiseni, ukusatshalaliswa kwamandla nezinhlelo zokulawula ezindaweni zokuhlala, ezentengiso nezezimboni. Isibonelo, izintambo ezisetshenziswa e-wiring yasendlini, amasekethe okukhanyisa kanye nemishini emincane.

Ukwakhiwa nezinto zokwakha

Ukwakheka kwezintambo eziphakeme zamandla aphezulu kuyinkimbinkimbi kakhulu kunaleso sezintambo eziphansi zamandla aphansi. Izintambo eziphakeme zamandla aphezulu zivame ukuhlanganisa izingqimba eziningi, kufaka phakathi nabaqhubi, abathambisi, izihlangu kanye nemifudlana yangaphandle. Izinto zokwakha ezifakiwe zibalulekile ukuvikela ukuvuza futhi ziqinisekise ukuphepha. Izinto ezisetshenziswayo ezisetshenziswayo ezisetshenziselwa izintambo zegesi eziphakeme zifaka i-polyethylene exhumene nesiphambano (i-XLPE) ne-ethylene-propypene rubber (EPR).

Izintambo zegesi eziphansi ngokuvamile zilula ekwakhiweni, yize zidinga izinto ezisezingeni. Zivame ukufakwa ku-PVC (polyvinyl chloride) noma irabha, eyanele izilinganiso eziphansi ze-voltage. Izinto zomqhubi zingahluka, kepha ithusi ne-aluminium kuyizinketho ezivame kakhulu zezicelo eziphakeme neziphansi ze-voltage.

Ukusebenza nokuphepha

Izintambo eziphakeme zamandla kagesizinenjinizo ukubekezelela izimo ezimbi kakhulu, kufaka phakathi amazinga okushisa aphezulu, ukucindezelwa kwemishini kanye nezici zezemvelo. Ngokuvamile zihlolwe amandla e-dielectric, alinganisa amandla wentambo wokumelana nokuqhekeka kukagesi. Lokhu kubalulekile ekuqinisekiseni ukuphepha nokwethenjwa kohlelo lokuhambisa amandla.

Ngokuphambene, izintambo eziphansi zamandla aphansi zenzelwe izindawo ezifunwa kakhulu. Ngenkathi zisadinga ukufeza amazinga okuphepha, izidingo zokusebenza azihlangene njengezintambo eziphakeme zamandla amavolo. Kodwa-ke, amakhekhe aphansi ama-voltage kumele ahambisane namakhodi kagesi endawo kanye nemigomo yokuqinisekisa ukusebenza okuphephile.

Isicelo

Izicelo zezintambo eziphakeme zamandla aphezulu nezintambo eziphansi zamandla ahlukile. Izintambo eziphakeme zamandla kagesi zisetshenziswa ikakhulukazi ekukhiqizweni kwamandla, izinhlelo zokuhambisa kanye nokusabalalisa. Bagxeka ukuxhuma imithombo yamandla evuselelekayo efana nomoya kanye namapulazi elanga kugridi.

Kodwa-ke, izintambo eziphansi zamandla aphansi zinobuhlakanize empilweni yansuku zonke. Zisetshenziselwa ukuhlala izintambo, izakhiwo zezentengiso kanye nezindawo zezimboni ukukhanyisa, ukushisa kanye namandla ahlukahlukene wemishini. Ukusebenza kwabo okuhlukahlukene kubenze balungele izinhlelo ezahlukahlukene zezicelo, kusuka kumasekhethi asekhaya alula kuya kwezinhlelo eziyinkimbinkimbi zokulawula ekwakhiweni kwezitshalo.

Ekuphetheni

Ngamafuphi, ukukhethwa kwamakhekhe aphezulu kanye nama-voltage amakhekhe ancike kwizidingo ezithile zohlelo lukagesi oluhambisanayo. Izintambo ze-High-Voltage zibalulekile ekudluliseleni ngogesi okulungele amabanga amade, kanti izintambo eziphansi zamandla aphansi zibalulekile ezinhlelweni zikagesi zansuku zonke. Ukuqonda umehluko osemqoka ekwakheni, ukusebenza, futhi uhlelo lokusebenza lungasiza ochwepheshe ukuba basebenzise izinqumo ezinolwazi ukuqinisekisa ukuphepha nokwethenjwa kwezinhlelo zabo zikagesi. Noma ngabe uklama igridi kagesi entsha noma i-wiring yasekhaya, wazi ukuthi uzosebenzisa nini izintambo ze-high-voltage kanye nama-voltage amakhekhe kubalulekile empumelelweni.
