FAQ

 

Q: Qhov txawv ntawm tooj liab core siab -voltage cables thiab aluminium core siab -voltage cables yog dab tsi? Yuav xaiv li cas?

A: Qhov sib txawv tseem ceeb nyob rau hauv cov khoom siv thiab kev siv cov xwm txheej: ① Conductivity: Copper core cables muaj qhov tsis zoo (tsawg dua lossis sib npaug li 0.017241 Ω· mm ² / m), tsis tshua muaj kev sib kis, thiab muaj peev xwm nqa tam sim no; Aluminium tub ntxhais cables muaj siab resistivity (tsawg dua los yog sib npaug rau 0.0282 Ω· mm ² / m), siab kis tau tus mob, thiab tsis tshua muaj peev xwm nqa tam sim no; ② Mechanical zog: Copper core cables muaj ductility zoo heev thiab tensile zog, thiab tsis yooj yim tawg los yog hnub nyoog; Aluminium tub ntxhais cables tsis zoo ductility thiab muaj oxidation thiab xoob pob qij txha tom qab siv ntev -; ③ Lub neej kev pab cuam: tooj liab tub ntxhais cables muaj lub neej kev pab ntau tshaj los yog sib npaug rau 30 xyoo, thiab txhuas core cables muaj kev pab lub neej ntawm tsawg dua los yog sib npaug rau 20 xyoo; ④ Tus nqi: Cov tub ntxhais tooj liab cables muaj cov nqi khoom siv siab, thaum aluminium cores muaj cov nqi qis. Cov lus qhia xaiv: Rau cov xwm txheej nrog nruab nrab mus rau high voltage, siab zog, ntev - kis tau tus mob, thiab ntev - lub sij hawm ua hauj lwm (xws li lub hwj chim kab rov tav kab, industrial hnyav loads, thiab tshiab zog fais fab chaw nres tsheb), tooj liab core high -voltage cables yog nyiam; Aluminium core cables tuaj yeem xaiv rau qhov tsis tshua muaj hluav taws xob, luv luv, kev siv hluav taws xob ib ntus, thiab cov xwm txheej raug nqi.

Q: Yuav ua li cas xaiv ntawm ib leeg tub ntxhais thiab peb core tooj liab core siab -voltage cables?

A: Raws li qib voltage, qhov chaw teeb tsa, thiab cov kev xav tau sib kis, xaiv: ① Voltage theem: 10kV ~ 35kV nruab nrab voltage scenario, ua qhov tseem ceeb ntawm peb cov qauv rau kev txhim kho siab thiab kev ua haujlwm me me; 110kV ~ 220kV ultra-high voltage scenario, qhov tseem ceeb tau muab rau ib leeg qauv, haum rau ultra-siab voltage kis thiab ntev- deb tso; ② Muab qhov chaw: qhov chaw me me xws li cable trenches, cable trays, underground yeeb nkab galleries, thiab lwm yam. Xaiv ib tug peb core qauv, tsis xav tau ntau yam nteg, txuag chaw; Sab nraum zoov nyiaj siv ua haujlwm, ntev - nrug cais tso, ib leeg qauv, hloov tau yooj yim khoov, haum rau ntev - txoj kev deb; ③ Cov kev xav tau ntawm kev sib kis: Peb theem fais fab mov, tsis tas yuav tsum muaj cov txheej txheem sib cais (cov nroj tsuag kev lag luam, kev tsim vaj tsev hauv nroog), xaiv peb lub hauv paus qauv; Cov xwm txheej uas yuav tsum tau hloov pauv theem sib cais thiab kev saib xyuas kev sib cais (ultra-high voltage kis tau tus mob, theem sib cais fais fab mov hauv cov chaw faib khoom), nrog rau cov qauv tseem ceeb.

Q: Yuav ua li cas xaiv qhov ntsuas voltage thiab tus neeg xyuas pib hla- ntu ntawm cov tub ntxhais tooj liab siab -voltage cables?

A: ① Rated voltage xaiv: Raws li qhov ntsuas hluav taws xob ntawm lub zog hluav taws xob, nws yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm "kab hluav taws xob ntsuas hluav taws xob U0 / U Ntau dua lossis sib npaug rau qhov ntsuas hluav taws xob" thiab hloov mus rau qhov siab tshaj plaws ua haujlwm ntawm lub kaw lus. Piv txwv li, hauv 10kV fais fab kab hluav taws xob (qhov siab tshaj plaws ua haujlwm voltage 12kV), xaiv cov cables nrog U0/U=8.7/10kV; 35kV industrial system (qhov siab tshaj plaws kev khiav hauj lwm voltage 40.5kV), xaiv U0/U=26/35kV cable; Xaiv cov cables nrog U0/U=127/220kV rau 220kV ultra{16}}high voltage system. ② Tus neeg xyuas pib hla- ntu xaiv: txiav txim siab raws li tag nrho lub zog thauj khoom, kis tau tus mob nyob deb, thiab tso cai poob. Cov qauv tseem ceeb yog: tus neeg xyuas pib hla- ntu S (mm ²) Ntau dua lossis sib npaug rau (P × L) / (K × Δ U × U ²) (P yog lub zog thauj khoom, L yog kis tau tus mob, K yog tooj liab conductor conductivity, Δ U yog tso cai tsis muaj hluav taws xob); Nyob rau tib lub sijhawm, nws yuav tsum ua kom tau raws li qhov yuav tsum tau muaj peev xwm nqa tau tam sim no, tsis txhob muaj cua sov ntau dhau, thiab tseem xav txog kev poob corona hauv ultra- qhov xwm txheej siab voltage. Piv txwv li: Ib qho 35kV system nrog lub zog thauj khoom ntawm 5000kW, kev sib kis deb ntawm 1km, thiab qhov tso cai qhov hluav taws xob poob ntawm 5%. Nws raug nquahu kom xaiv 3 × 240mm ² (peb core) lossis 240mm ² (ib leeg tub ntxhais) tus neeg xyuas pib hla -section.
