Q: Yuav ua li cas xaiv ntawm ib tug tub ntxhais thiab peb core aluminium core siab -voltage cables?
A: Xaiv raws li qib voltage, qhov chaw teeb tsa, thiab qhov yuav tsum tau sib kis: ① Voltage theem: 6kV ~ 35kV nruab nrab voltage scenario, ua ntej peb cov qauv, kev ua haujlwm siab, kev ua haujlwm me me, tsim nyog rau kev faib khoom siv hluav taws xob thiab cov khoom siv fais fab; 64kV ~ 110kV nruab nrab thiab high voltage scenarios, nrog rau qhov tseem ceeb rau ib leeg qauv, haum rau nruab nrab thiab luv luv kis tau tus mob thiab overhead tso ntawm nruab nrab thiab high voltage; ② Muab qhov chaw: Cable trenches, cable tais, underground yeeb nkab galleries, lub tsev pipelines thiab lwm qhov chaw nqaim, xaiv ib tug peb core qauv, tsis xav tau ntau yam nteg, txuag chaw; Sab nraum zoov nyiaj siv ua haujlwm, ntev - qhov deb traction nteg, ib qho qauv tsim, qhov zoo ntawm lub teeb yuag, hloov tau yooj yim, thiab yooj yim tso; ③ Cov kev xav tau ntawm kev sib kis: Peb theem hluav taws xob, tsis tas yuav tsum muaj cov txheej txheem sib cais (lub nroog thiab cov neeg nyob deb nroog, cov tsev siab - nce siab, muaj chaw ua si), 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 (nruab nrab thiab siab voltage tis tes hauj lwm, lub hauv paus tunnels), nrog rau ib qho qauv tseem ceeb.
Q: Yuav ua li cas xaiv qhov ntsuas hluav taws xob thiab tus neeg xyuas pib hla -section ntawm aluminium core siab -voltage cables?
A: ① Rated voltage xaiv: txiav txim siab 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 qhov system. Piv txwv li, nyob rau hauv 10kV tis network system (siab tshaj plaws ua hauj lwm voltage 12kV), xaiv cables nrog U0/U=6/10kV; 35kV industrial auxiliary system (siab tshaj plaws ua haujlwm voltage 40.5kV), xaiv U0/U=26/35kV cable; Xaiv cov cables nrog U0/U=64/110kV rau 110kV nruab nrab thiab siab voltage system. ② Tus neeg xyuas pib hla-section xaiv: Aluminium core cables yuav tsum tau xaiv raws li "tooj liab core cross-section × 1.5 zaug" (vim yog qhov tsis zoo ntawm aluminium conductivity), txiav txim siab raws li tag nrho cov load zog, kis tau tus mob 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 × 1.5) / (K × Δ U × U ²) (P yog lub zog thauj khoom, L yog kis nrug deb, K yog aluminium conductor conductivity, Δ U yog tso cai voltage poob); Nyob rau tib lub sijhawm, nws yuav tsum ua kom tau raws li qhov yuav tsum tau muaj peev xwm nqa tam sim no, tsis txhob muaj cua sov ntau dhau, thiab tseem xav txog kev poob corona hauv qhov nruab nrab thiab siab voltage scenarios. Piv txwv li: Ib qho 35kV system nrog lub zog thauj khoom ntawm 3000kW, kev sib kis deb ntawm 0.8km, thiab qhov tso cai qhov hluav taws xob poob ntawm 5%. Nws raug nquahu kom xaiv tus neeg xyuas pib hla- ntu ntawm 3 × 300mm ² (peb core) lossis 300mm ² (ib leeg tub ntxhais).
Q: Puas yog txhuas core siab -voltage cables siv rau sab nraum zoov, hauv av, chaw ua si thiab lwm qhov chaw?
A: Okay. Qhov no series ntawm aluminium core high -voltage cables muaj huab cua tiv thaiv zoo heev, corrosion resistance, thiab mechanical zog, thiab tuaj yeem hloov mus rau cov chaw ib puag ncig xws li sab nraum zoov, hauv av, chaw ua si, siab -nce vaj tse, thiab lwm yam.: ① Sab nraum zoov ib puag ncig: huab cua PE, tsis muaj pa taws halogen- dawb PE cua sov, tiv thaiv tshav kub, tsis muaj ultraviolet thiab nag thiab lwm yam., ntev - lub sij hawm sab nraum zoov pw tsis muaj kev laus los yog tawg; ② Ib puag ncig hauv av: Galvanized armor txheej thiab corrosion- tiv thaiv sheath tuaj yeem tiv taus av corrosion, noo noo, thiab av yaig, tsis txhob xeb thiab rwb thaiv tsev puas los ntawm ib puag ncig hauv av; ③ Muaj chaw ua si hauv chaw ua si: Roj resistant thiab corrosion-cov ntaub thaiv npog tuaj yeem tiv taus cov roj rhiav thiab tshuaj lom neeg corrosion, haum rau cov cheeb tsam nyuaj hauv cov chaw ua si; ④ Kev nce siab hauv ib puag ncig: Cov qauv teeb pom kev zoo tsim nyog rau kev teeb tsa ntsug, nplaim hluav taws ua haujlwm tau raws li qhov xav tau ntawm kev nyab xeeb hluav taws, tsim nyog rau cov xwm txheej uas muaj neeg coob coob; ⑤ Cov xwm txheej nruab nrab thiab qhov hluav taws xob siab: Lub siab tawv thiab cov ris tsho tuaj yeem tiv taus qhov kub thiab txias, av noo, thiab sab nraud cuam tshuam, thiab tsim nyog rau nruab nrab thiab siab voltage faib network scenarios.
