Kev sib ntsib cov qauv kev tiv thaiv tsuas yog qhov tsawg kawg nkaus xwb - cov khoom luv luv yog qhov txaus ntshai tiag tiag.
Nyob rau hauv xyoo tas los no, "ua pov thawj tsis kam" tau dhau los ua lus nrov hauv kev lag luam cable thiab cov ntawv cog lus: ib qho cuab yeej rau cov tuam txhab lag luam kom yeej tus nqi qis - cov nqi sib tw thiab cov neeg yuav los txiav cov nqi. Thaum xub thawj siab ib muag, cov cables no khij lub thawv ntawm ib qho kev ntsuas tseem ceeb -tus neeg xyuas pib DC tsis kam (ib GB / T 3956 thiab lwm yam qauv)- thiab zoo li muaj kev nyab xeeb. Tab sis raws li "lifeline" ntawm cov tshuab hluav taws xob, kev ruaj ntseg cable cuam tshuam ntau tshaj li ib tus lej. Txo kev nyab xeeb kom tsuas yog "kev tiv thaiv kev ua raws cai" yog qhov kev xav tsis zoo txaus ntshai ua rau lub neej thiab khoom ntiag tug. Cia peb rhuav qhov tseeb:
1. Kev Ua Raws Li Kev Ua Phem: Ib qho pib, tsis yog tag nrho zaj dab neeg
Thaum ntsib cov qauv kev tiv thaiv yog qhov tseem ceeb rau kev nyab xeeb, nws nyob deb ntawm qhov txaus. Cov neeg tsim khoom feem ntau txiav cov ces kaum rau lwm qhov txhawm rau txhawm rau tiv thaiv lub hom phiaj ntawm pheej yig:
Ib lub tuam txhab hluav taws xob tau raug kev txom nyem ntau dua 10 lab yuan hauv kev poob tom qab "tsis kam- lav" cable conductor snapped los ntawm luv luv Circuit Court tsuas yog ib xyoos rau kev siv.
Cov khoom siv hluav taws xob tsis zoo / cov ntaub thaiv npog (xws li, cov roj hmab silicone tsis zoo) tuaj yeem ua kom siab siab - qhov kub thiab txias tiv thaiv los ntawm 50% + (silicone roj hmab cables yuav tsum tuav ntau dua lossis sib npaug li 800 MΩ·km ntawm 180 degree), ua rau kev tiv thaiv tsis muaj txiaj ntsig.
2. Cov khoom siv luv luv: Tus nqi qis ntawm tus nqi qis
"Guaranteed resistance" feem ntau npog cov khoom siv zais cia:
Undersized conductors (piv txwv li, sau npe 2.5mm², tiag tiag 2.2mm²) nrog tooj liab-clad steel kom tau raws li kev ua haujlwm-slashing load peev 15% thiab ua rau overheating.
Thinner rwb thaiv tsev (piv txwv li, ZA-KVVP tswj cables nrog 0.5mm es tsis txhob nominal 0.7mm)-tej voltage tiv taus los ntawm 1.5kV/min rau<1kV, risking surge damage.
Cov nplaim hluav taws uas ploj lawm: 2024 qhov hluav taws kub tshwm sim los ntawm "kev tiv thaiv-ua raws" RVSVP cables-oxygen index 10% hauv qab cov qauv hauv tebchaws (GA/T 1297-2021).
3. Cov xwm txheej tshwj xeeb: Kev Nyab Xeeb=Kev Tiv Thaiv + Ib puag ncig Adaptability
Cables yuav tsum ua dhau qhov kev tiv thaiv hauv cov chaw tshwj xeeb:
Siab -kub/corrosion: ZC-KGG-22 silicone roj hmab cables yuav tsum tau tsawg dua los yog sib npaug li 20% rwb thaiv tsev tsis kam poob ntawm 180℃- pheej yig lwm yam hnub nyoog sai tshaj 100℃.
Mining: GB 43069-2023 xav tau hluav taws xob, hluav taws xob, thiab hluav taws xob-kev nyab xeeb tsis zoo- cov kab hluav taws xob tsuas yog cuam tshuam cov sheath rupture thiab roj tawg.
Teeb liab kis tau tus mob: ASTP-120Ω cables xav tau tsawg dua lossis sib npaug ntawm 0.06 μF / km capacitance-subpar versions ua rau subway tsheb ciav hlau tsis ua haujlwm (40% dhau tus qauv).
Hydraulic engineering: YSPT soj ntsuam cables xav tau UV / hydrolysis tsis kam- cov khoom luv luv cia cov dej noo nkag rau hauv, cuam tshuam cov teeb liab.
4. Tsim kom muaj kev nyab xeeb tiag tiag: Tech, qauv, thiab kev saib xyuas
Txhawm rau kho qhov "kev nyab xeeb=tsis kam" lus dab neeg, txhua tus neeg muaj feem cuam tshuam yuav tsum ua:
Technology: Txais kev ntsuas kev ua tau zoo (piv txwv li, 180℃/ 1000h laus, -60℃dabtsi yog khoov rau ZC-KGG-22).
Cov qauv: Ua raws li qhov xwm txheej- cov kev cai tshwj xeeb (xws li 2025's GB/T 5054.1-2024 ntxiv roj / tshuaj tiv thaiv rau lub tsheb cables).
Kev cai: Txhim khu cov ntaub ntawv traceability (xws li, MA daim ntawv pov thawj rau cov mining cables yuav tsum tau cov ntaub ntawv raw cov ntaub ntawv thiab thib peb -cov ntaub ntawv qhia tog).
Cov neeg yuav khoom: Ua raws li "peb daim tshev": txheeb xyuas CMA/CNAS-cov ntawv pov thawj xeem ntawv pov thawj, lees paub tag nrho cov qauv ua raws, thiab tshuaj xyuas cov khoom siv hluav taws xob / rwb thaiv tsev.
Cov kab hluav taws xob muaj kev nyab xeeb zoo li kev noj qab haus huv zoo - ntshav siab (kuj) yog qhov tseem ceeb, tab sis koj xav tau lub cev noj qab haus huv. Kev nyab xeeb tiag tiag los ntawm kev ua raws li cov qauv kev tiv thaiv, siv cov khoom zoo, muaj cov qauv zoo, thiab haum rau ib puag ncig.
