Amalungu esakhiwo sentambo yamandla
Nje,Intambo yamandla ye-AC enesatifikethi se-ULziyilelwe ukuthwala yangoku isuka kumthombo oluncedo okanye into eluncedo yamandla ukuya kumthengi wayo.Zinoyilo oluhle, njengomthetho, ngokutshintshana okwangoku kwi-10-35 kV, kodwa kukho iintlobo eziqhelekileyo zokudlulisa okwangoku kwi-220-330 kV.Iingcingo ezinjalo ziqhagamshelwe kwiindawo ezimileyo okanye eziphathwayo.
Siyisebenzisa phi intambo yombane ye-AC enesatifikethi se-UL?
Amacandelo okwakhiwa kobhedu okanye i-aluminium intambo yamandla aya kuhluka ngokuxhomekeke kwinto eqhelekileyo yocingo.Nangona kunjalo, kukho izinto ezinjalo ukuba akukho mveliso inokuyenza ngaphandle:
abaqhubi;
ukugquma okungundoqo;
iqokobhe
isigqubuthelo sangaphandle, esiphathiswe imisebenzi yokukhusela.
NgamnyeIntambo yamandla ye-AC enesatifikethi se-ULine-insulation eqhelekileyo.Ngokufanayo, siyibiza ngokuba yi-belt insulation.Uyilo lweentambo zamandla luthatha ukusuka kwi-conductor enye ukuya kwabahlanu.Imithambo ngokwayo ingaba yingqukuva okanye i-triangular kwimilo, inokuba necandelo.Kukho iimodeli ezinocingo olulodwa okanye ngeengcingo ezininzi ezenza i-core.
Ungayifumana phi intambo yamandla e-AC enesatifikethi se-UL?
Kwintambo, sibabuyisela ngokufana okanye bajijekile.Iklasi engundoqo inokusuka kwi-1 ukuya kwi-6.Inkampani yethu iya kukunika unikezelo lwamandla amathathu-angundoqo okanye i-4-core cord (ubhedu, i-aluminium) kumaxabiso aphantsi kunye nangexesha elifutshane.
Ngokuqhelekileyo kukho i-core zero kwintambo, ethatha indima ye-conductor engathathi hlangothi, kunye nentambo yokumisa, esebenza njengokukhusela ekuvuzeni kombane.
Zeziphi iimpawu ezithwala intambo yamandla ye-AC enesatifikethi se-UL?
Amacala amabiniIntambo yamandla ye-AC enesatifikethi se-ULinokuza nekhaka elinciphisa impembelelo yentsimi ye-electromagnetic, kwaye yenza ibala elijikeleze umqhubi wangoku olinganayo.Phakathi kwezinye izinto, isikrini esinjalo siya kwenza ukuba ucingo luxhathise ngakumbi kwiimpembelelo zangaphandle kunye nokuqinisa ukugquma kwayo.
Ukuba kukho umngcipheko wokuba intambo iya konakaliswa ngenxa yeempembelelo zangaphandle, kunengqiqo ukusebenzisa iimveliso ze-armored.Iintambo zamandla ezixhotyisiweyo zangoku ziya kumelana ngempumelelo:
ukuba sesichengeni kwiintubi, iimbovane, iimpuku kunye nezinye izinambuzane;
Ngaphezu koko, ukubetha ngengozi ngesixhobo ngexesha lokulungiswa kunye nomnye umsebenzi;
ukucudisa, ukucudisa, njl.
Iintlobo zeentambo zamandla
Kwinkampani yethu, ungathenga iintlobo ezahlukeneyo zeentambo zombane zamandla (eziguquguqukayo, kunye nabaqhubi bezobhedu bamacandelo ahlukeneyo, kunye ne-PVC insulation, njl.) ngexabiso elifikelelekayo.Sinokhetho kwii-assortment:
ukumelana nomlilo - akubonakali kumlilo ovulekileyo;
Ngaphezu koko, ikhuselwe - isikhuseli esongezelelweyo se-foil sinikezelwa;
irabha - kunye nokhuseleko olongezelelweyo lwerabha;
Ngokufanayo, i-armored - kunye negobolondo ehlala ixesha elide;
nge-PVC insulation - ilungele umhlaba ongcwatywe;
Ngokufanayo, kunye nokufakwa kweplastiki - kuxhomekeke kwiqondo lokushisa kwendalo kunye nombane ofunekayo;
ngokufakelwa kwe-XLPE.
Ungathenga nayiphi na imodeli efunekayo kuthi.Unokuthenga i-flexible, i-acoustic, i-spiral, i-resistant-fire, i-armoredIntambo yamandla ye-AC enesatifikethi se-UL.Iimveliso zinokuba ngaphantsi kwamanzi, zingcwatywe okanye zizixhase, kwaye ixabiso liya kuba lelinye lawona maxabiso anenzuzo kakhulu kwimarike.
Izinto eziphathekayo kunye necandelo elinqamlezayo lentambo yamandla e-AC enesatifikethi se-UL
Kukho iintlobo ezimbini zezinto ezinokuthi zenziwe ngabaqhubi - i-aluminium kunye nobhedu.I-cross-section of aluminium conductors ihambelana ngokuthe ngqo nenani leengcingo eziza kwenza i-core.Ukuxhomekeka kuko oku kulandelayo:
kunye necandelo lomnqamlezo ukuya kuthi ga kwi-35mm2(kuquka), undoqo uza ngocingo olunye kuphela;
Ngaphezu koko, kunye necandelo lomnqamlezo ukuya kuthi ga kwi-300mm2, iingcingo enye okanye ngaphezulu ziqhelekileyo;
Ngecandelo lomnqamlezo we-300-800mm2, iingcingo ezininzi ziqhelekile.
Ukuba ufuna ukuthenga iingcingo zamandla kwibhetri okanye ukubekwa kwangaphandle kunye nabaqhubi bobhedu ngexabiso lomenzi, kubalulekile ukwazi ukuba imeko ihluke apha kune-aluminium.
Abaqhubi be-single-wire conductors banokuba nendawo enqunywe ukuya kwi-16mm2, kunye neentambo ezininzi - 120-180mm2.Ngommandla onqamlezayo we-25-90mm2, zombini enye kunye neengcingo ezininzi zinokuqhelekileyo.
Kuyafaneleka ukwazi ukuba i-zero core inendawo encinci ye-cross-sectional.Isiseko esinjalo siphakathi kwabanye kwaye siphawulwe ngeblue phantsi kwemeko yangoku yesigaba sesithathu.
Izinto eziluncedo kwintambo yamandla obhedu
Iingcingo zeAluminiyam zinenye engenakuphikiswa - ziyafumaneka.Ngaphezu koko, i-aluminiyam ngokwayo ikumgangatho ophezulu kwaye iconductor exabiso liphantsi eyenza umsebenzi obalaseleyo kuyo yonke imisebenzi eyabelwe yona.AluminiyamIntambo yamandla ye-AC enesatifikethi se-UL, njengomthetho, kuqhelekile ukudala imigca yamandla emide.
Nangona kunjalo, kukho izizathu ezininzi ezibonisa ukuba iingcingo zobhedu zingcono kakhulu kwiinethiwekhi zasekhaya.
Inyaniso kukuba:
- iplastiki eninzi kwaye ungaphuli xa ugoba, njenge-aluminium;
- Ngokufanayo, aziyi kunyibilika kwaye zingabi buthathaka, njenge-aluminium, ngokunyuka kokuchasana koqhagamshelwano, zithembeke kakhulu;
- intambo yamandla exhobileyo eyenziwe ngobhedu iya kumelana nemithwalo ephezulu kakhulu kune-aluminium, ekubeni kwinqanaba elifanayo elinqamlezayo liya kuba ne-resistiveivity ephantsi kwaye, ngenxa yoko, ukuhanjiswa kombane okuphezulu.
Ngoko ke, kungcono ukuthenga amandla angaphantsi komhlaba okanye ucingo lobhedu lomhlaba kunye ne-aluminium ekhoyoIntambo yamandla ye-AC enesatifikethi se-ULkunye necandelo lomnqamlezo ukuya kwi-16mm2 kwaye ubuyisele iintambo ezindala.Kunconywa ukuba utshintshe iimveliso kunye ne-cross-section enkulu kwiingcingo zobhedu, kodwa kufuneka kukhunjulwe ukuba ubhedu lubiza kakhulu kune-aluminium.
Intambo yamandla ye-AC eneSiqinisekiso se-UL yesatifikethi
Iinjongo zeengcingo kunye nezinto ezikhethekileyo zemveliso yazo ziya kuchaphazela kakhulu iimpawu zobugcisa zemveliso.Ucingo lofakelo lwamandla lunokwahluka kwinani leeparamitha:
- inani leemithanjeni linokuba ukusuka kwelinye ukuya kwisihlanu;
- izinto eziphambili - i-aluminium okanye ubhedu;
- indawo enqamlezileyo yombindi;
- uhlobo lokugquma ucingo.
Ngokuxhomekeke kwezi mpawu, i-voltage emelene nocingo, iqondo lokushisa eligcina ukusebenza kwayo, kunye nobomi benkonzo buya kuxhomekeka.
Unokukhetha njani intambo yamandla ombane aphezulu we-AC enesatifikethi se-UL?
Siya kukwazi ukubonelela ngeengcebiso ezicacileyo malunga nendlela yokukhetha intambo yamandla ombane ophezulu (kunye okanye ngaphandle kwentambo ngaphakathi), apho imveliso ixhaphake khona, ixabisa kangakanani kwaye yintoni ubomi bayo benkonzo.Kwanele ukusibiza kwaye uthethe neengcali eziqeqeshiweyo.
A professional uya kuba nako ukunika ulwazi ukuba enjaloIntambo yamandla ye-AC enesatifikethi se-ULukusebenza kumaqondo obushushu ukusuka +50 ukuya kwi-50 degrees, kwaye ubomi benkonzo, ukuba buqhelekile ngokuchanekileyo, bunokufikelela kwiminyaka engama-30.
Ubuninzi bentambo yamandla eflethi okanye olunye uhlobo lunokumelana ne-330 kV yombane.Kukho iindidi zeentambo zokugquma eziya kuxhomekeka kuhlobo lokugquma.Oko kukuthi:
- iphepha - ukuya kuthi ga kwi-35kV;
- irabha - ukuya kuthi ga kwi-10kV;
- I-PVC - ukuya kuthi ga kwi-6kV.
Ukuqukumbela intambo yamandla e-AC enesatifikethi se-UL
Ngokuxhomekeke kwinjongo, kwikhathalogu yethu unokufumana iimpawu ze-multicore eziguquguqukayoIntambo yamandla ye-AC enesatifikethi se-ULyokulala emhlabeni, i-flame-retardant (i-fire-resistant), kwisikrweqe kunye nabanye.
Kuyafaneleka ukukhetha imveliso ngokuxhomekeke kwimisebenzi eya kunikwa yona.Ukuze ucingo lusebenze ixesha elide, kufuneka ubeke ingqalelo kwiimveliso eziza kulungeleka kakhulu kwiimeko zokusebenza.
