Izingxenye zesakhiwo sentambo yamandla
Ngenjwayelo,Intambo yamandla ye-AC enezitifiketi ze-ULzakhelwe ukuthwala zamanje zisuka emthonjeni osetshenziswayo noma ezisetshenziswa amandla ziye kumthengi wazo. Zinomklamo omuhle, njengomthetho, wokushintshanisa okwamanje ku-10-35 kV, kodwa kunezinhlobonhlobo ezivamile ukudlulisa okwamanje ku-220-330 kV. Izintambo ezinjalo zixhunywe ekufakweni okumile noma okuhambayo.
Siyisebenzisa kuphi intambo yamandla e-AC nesitifiketi se-UL?
Izingxenye zesakhiwo sentambo yamandla yethusi noma i-aluminium zizohluka kakhulu kuye ngokuthi ucingo lujwayele ukuthini. Kodwa-ke, kunezakhi ezinjalo okungekho umkhiqizo ongakwenza ngaphandle:
abaqhubi;
i-core insulation;
igobolondo;
isembozo sangaphandle, esiphathiswe imisebenzi yokuvikela.
NgamunyeIntambo yamandla ye-AC enezitifiketi ze-ULine-insulation evamile. Ngokufanayo, sikubiza ngokuthi i-belt insulation. Idizayini yezintambo zamandla ithatha iconductor eyodwa kuya kweyisihlanu. Imithambo ngokwayo ingaba yindilinga noma i-triangular ngesimo, ingaba yi-sectorial. Kunamamodeli anocingo olulodwa noma anezintambo eziningi ezakha umongo.
Ungayithola kuphi intambo yamandla e-AC ngesitifiketi se-UL?
Entanjeni, sibashintsha ngokufana noma basontekile. Isigaba esiyinhloko singasuka ku-1 siye ku-6. Inkampani yethu izokunikeza ukuhlinzekwa kwamandla amathathu-core noma amane-core (ithusi, i-aluminium) ngamanani aphansi nangesikhathi esifushane.
Ngokuvamile kukhona i-zero core entanjeni, ethatha indima yomqhubi ongathathi hlangothi, kanye nentambo yomhlabathi, esebenza njengesivikelo ekuvuzeni kukagesi.
Yiziphi izici ezithwala intambo yamandla ye-AC enezitifiketi ze-UL?
I-two-coreIntambo yamandla ye-AC enezitifiketi ze-ULingafika nesihlangu esinciphisa ithonya lensimu kazibuthe, futhi yenza inkambu ezungeze umqhubi wamanje ilingane. Phakathi kwezinye izinto, isikrini esinjalo sizokwenza ucingo lukwazi ukumelana namathonya angaphandle futhi luqinise ukufakwa kwalo.
Uma kunengozi yokuthi intambo izolimala ngenxa yamathonya angaphandle, kunengqondo ukusebenzisa imikhiqizo ye-armored. Izintambo zamandla ezikhali zesimanje zizomelana ngempumelelo:
ukuchayeka emihlwa, izintuthwane, amagundane nezinye izinambuzane;
Ngaphezu kwalokho, ukushaya ngephutha ngethuluzi ngesikhathi sokulungiswa kanye nomunye umsebenzi;
ukuncinza, ukuncinza, njll.
Izinhlobo zezintambo zamandla
Enkampanini yethu, ungathenga izinhlobo ezahlukene zezintambo zikagesi zamandla (eziguquguqukayo, ezinama-conductor zethusi zezigaba ezahlukene, nge-PVC insulation, njll) ngezindleko ezingabizi. Sinezinketho ku-assortment:
ukumelana nomlilo - akuvezwa emlilweni ovulekile;
Ngaphezu kwalokho, kuvikelwe - isihlangu esengeziwe se-foil sinikezwa;
irabha - ngokuvikelwa okwengeziwe kwe-rubberized;
Ngokufanayo, i-armored - ngegobolondo elihlala njalo;
nge-PVC insulation - ifanele indawo engcwatshwe;
Ngokufanayo, nge-plastic insulation - kuncike ekushiseni kwemvelo kanye ne-voltage edingekayo;
nge-insulation ye-XLPE.
Ungathenga noma iyiphi imodeli edingekayo kithi. Ungathenga okuguquguqukayo, i-acoustic, i-spiral, ukumelana nomlilo, i-armoredIntambo yamandla ye-AC enezitifiketi ze-UL. Imikhiqizo ingaba ngaphansi kwamanzi, ingcwatshwe noma ikwazi ukuzisekela, futhi intengo izoba enye yenzuzo kakhulu emakethe.
Izinto kanye nengxenye yentambo yamandla ye-AC enesitifiketi se-UL
Kunezinhlobo ezimbili zezinto lapho ama-conductor angenziwa khona - i-aluminium nethusi. I-cross-section ye-aluminium conductors ihlobene ngokuqondile nenani lezintambo ezizokwenza umnyombo. Ukuncika kungokulandelayo:
ngesigaba esiphambanayo esingafika ku-35mm2(okuhlanganisiwe), ingqikithi iza ngocingo olulodwa kuphela;
Ngaphezu kwalokho, nge-cross section of up to 300mm2, intambo eyodwa noma ngaphezulu zivamile;
Nge-cross section ye-300-800mm2, izintambo eziningana zivamile ngempela.
Uma udinga ukuthenga izintambo zamandla ebhethri noma ngokubeka ngaphandle ngamakhondatha ethusi ngentengo yomkhiqizi, kubalulekile ukwazi ukuthi isimo sihlukile lapha kune-aluminium.
Amakhondaktha anocingo olulodwa angaba nendawo esikiwe efinyelela ku-16mm2, kanye nezintambo eziningi - 120-180mm2. Nge-cross-sectional area engu-25-90mm2, kokubili izintambo ezilodwa neziningana zingaba zivamile.
Kuyafaneleka ukwazi ukuthi i-zero core inendawo encane ye-cross-sectional. Umongo onjalo utholakala phakathi kwabanye futhi umakwe ngokuluhlaza okwesibhakabhaka ngaphansi kwesimo samanje sezigaba ezintathu.
Izinzuzo zentambo yamandla ethusi
Izintambo ze-aluminium zinokuhlanganisa okukodwa okungenakuphikwa - ziyatholakala. Ngaphezu kwalokho, i-aluminium ngokwayo ingumqhubi wekhwalithi ephezulu futhi oshibhile owenza umsebenzi omuhle kakhulu wayo yonke imisebenzi eyabelwe yona. I-AluminiumIntambo yamandla ye-AC enezitifiketi ze-UL, njengomthetho, kuvamile ukudala izintambo zamandla ezinde.
Kodwa-ke, kunezizathu eziningi ezibonisa ukuthi izintambo zethusi zingcono kakhulu kumanethiwekhi asekhaya.
Into ukuthi bona:
- ipulasitiki eningi futhi ungaphuli lapho ugoba, njenge-aluminium;
- Ngokufanayo, azincibiliki futhi azenzi buthaka, njenge-aluminium, ngokunyuka kokumelana nokuxhumana, zithembeke kakhulu;
- intambo yamandla e-armored eyenziwe ngethusi izomelana nemithwalo ephakeme kakhulu kune-aluminium, ngoba esigabeni esifanayo izoba nokumelana okuphansi futhi, ngenxa yalokho, i-conductivity kagesi ephakeme.
Ngakho-ke, kungcono ukuthenga amandla angaphansi komhlaba noma ucingo lwethusi lomhlabathi nge-aluminium ekhonaIntambo yamandla ye-AC enezitifiketi ze-ULngesigaba esiphambanayo esingafika ku-16mm2 bese ubuyisela izintambo ezindala. Kunconywa ukushintsha imikhiqizo nge-cross-section enkulu kuzintambo zethusi, kodwa kufanele kukhunjulwe ukuthi ithusi libiza kakhulu kune-aluminium.
Intambo yamandla ye-AC enezicaciso zesitifiketi se-UL
Inhloso yezintambo kanye nezici zokukhiqiza kwazo zizothinta kakhulu izici zobuchwepheshe zomkhiqizo. Intambo yokufaka amandla ingahluka ngenani lamapharamitha:
- inani lemithanjeni lingaba kusuka kweyodwa kuya kwemihlanu;
- izinto eziyisisekelo - i-aluminium noma ithusi;
- indawo ephambanayo yomgogodla;
- uhlobo lwe-wire insulation.
Kuye ngalezi zici, i-voltage leyo ucingo imelana nayo, izinga lokushisa lapho igcina khona ukusebenza kwayo, kanye nempilo yesevisi izoxhomeka.
Ungayikhetha kanjani intambo yamandla kagesi we-AC ephezulu ngesitifiketi se-UL?
Sizokwazi ukunikeza iseluleko esiningiliziwe mayelana nendlela yokukhetha intambo yamandla kagesi aphezulu (enentambo noma ngaphandle kwayo), lapho umkhiqizo uvame khona, ubiza malini nokuthi iyini impilo yesevisi yayo. Kwanele ukusibiza futhi ukhulume nochwepheshe abaqeqeshiwe.
Uchwepheshe uzokwazi ukunikeza ulwazi olunjaloIntambo yamandla ye-AC enezitifiketi ze-ULukusebenza emazingeni okushisa kusuka ku-+50 kuya ku-50 degrees, futhi impilo yesevisi, uma ijwayelekile ngendlela efanele, ingaba yiminyaka engama-30.
Ubukhulu bentambo yamandla ayisicaba noma olunye uhlobo lungakwazi ukumelana nomthamo ofinyelela ku-330 kV. Kunezinhlobonhlobo zezintambo zokwahlukanisa ezizoncika ohlotsheni lwe-insulation. Okungukuthi:
- iphepha - kufika ku-35kV;
- irabha - kufika ku-10kV;
- I-PVC - kufika ku-6kV.
Isiphetho sentambo yamandla ye-AC nesitifiketi se-UL
Kuya ngenhloso, kukhathalogi yethu ungathola izinhlobo ze-multicore eziguquguqukayoIntambo yamandla ye-AC enezitifiketi ze-ULyokubeka phansi, i-flame-retardant (ukumelana nomlilo), igqoke izikhali nokunye.
Kuyafaneleka ukukhetha umkhiqizo ngokuya ngokuthi yimiphi imisebenzi ezonikezwa wona. Ukuze ucingo lusebenze isikhathi eside, udinga ukunaka imikhiqizo ezofaneleka kakhulu ezimweni zokusebenza.
