Kev faib tawm thiab cov kev xaiv npe ntawm cov hluav taws xob siab

Daim ntawv thov ntawm cov xaim ntawm cov kev sib txawv ntau ntau ntau ntau ntau, yog nyob ntawm qhov chaw voltage, thauj khoom, thiab ib puag ncig. Cov hauv qab no yog cov kev faib tawm ntawm cov hluav taws xob siab ntau thiab lawv cov ntawv thov raug cai:
1. Nruab nrab voltage Cable (1 kV ~ 35 kv)
Raug voltage theem:
3.3 KV, 6.6 KV, 10 KV, 20 KV, 33 kv
Daim Ntawv Thov Qhia:
Lub Nroog Spromotion network: Muab zog rau cov chaw nyob thiab cov chaw ua lag luam, xws li 10 kv cables siv dav hauv cov tes hauj lwm txuas ntxiv.
Muaj hluav taws xob: Muab hluav taws xob rau lub zog loj thiab nruab nrab xws li cov khoom siv thiab cov mines (xws li motors thiab transformers).
Lub zog txuas dua tshiab: Cov kab sib txuas txuas cov pob zeb cua thiab photovoltaic fais fab tuag (xws li 33 kv).
Cov qauv nta:
Rwb thaiv tsev cov khoom: Hla-txuas Polyethylene (XLPE) lossis ethylene pranten dej roj hmab (EPR).
Tus neeg xyuas khoom: Tooj lossis txhuas, xav tau daim ntaub thaiv npog kom txo hluav taws xob kev cuam tshuam.
2. Cov Khoom Siv Hluav Taws Xob Siab (66 KV ~ 220 KV)
Raug voltage theem:
66 kV, 110 KV, 132 KV, 220 KV
Daim Ntawv Thov Qhia:
Cov kev sib koom ua ke hauv cheeb tsam: Txuas lub zog loj hluav taws xob nruab nrab ntawm cov nroog (xws li 220 kv cables siv rau cross lub zog hluav taws xob).
Qhov chaw muaj kev thaj tsam loj: Muab cov hluav taws xob ncaj qha rau kev siv zog muaj zog xws li cov nroj tsuag hlau thiab tshuaj lom neeg.
Submarine CABLE: Daim phiaj sib txuas ntawm ntug dej ua liaj ua teb (xws li 110 kv AC lossis DC cables).
Cov qauv nta:
Cov rwb thaiv tsev txheej yog tuab thiab xlpe lossis roj lossis roj puv cable (ntawm cable) yog siv.
Multi txheej kev thaiv thiab hlau sheath (xws li Leased sheath) tiv thaiv kom noo infiltration.
3. Ultra High Voltage Cables (220 KV ~ 765 KV)
Raug voltage theem:
275 KV, 345 kV, 400 KV, 500 KV
Daim Ntawv Thov Qhia:
Kev sib kis tau ntev: Lub zog kis speaping ntau pua pua mais (xws li 500 kV kab siv los txuas lub zog nroj tsuag nrog cov chaw hluav taws xob nrog cov chaw tsim hluav taws xob nrog cov chaw tsim hluav taws xob).
Hla fais fab sib tsoo sib tsoo: xws li European Cross-ciam teb hluav taws xob fais fab loj (400 KV).
Cov Khoom Siv Hluav Taws Xob Loj: Kev ntseeg siab ntseeg lub zog rau Mega cov nroog lossis cov chaw haujlwm loj.
Cov qauv nta:
Cov kua ntim ua kua (xws li cov viscosity roj tsis muaj zog.
Ib qho yuam kev txias (xws li dej txias lossis cua txias) yuav tsum tau tiv nrog cov cua sov siab.
4. Ultra High Voltage cables (ntau dua lossis sib npaug rau 800 kV)
Raug voltage theem:
800 KV DC, 1000 KV AC (UHVAC), 1100 KV DC (UHVDC)
Daim Ntawv Thov Qhia:
Ultra Kev Sib Kis Txog Kev Nyab Xeeb: Txo cov kis tau (xws li kis kev sib nrug ntawm Suav teb tus ± 1100 KV Ultra-High Voltage Project tshaj 3000 Kilometers).
Hla ciam teb / transcontinental fais fab rooj sib chaws (xws li cov chaw taws teeb hluav taws xob (xws li cov chaw nres tsheb
Kev kis tau tam sim no (HVDC): Kev deb deb nrug nyob hauv qab dej (xws li kev sib koom ua ke ntawm North Hiav Txwv Cua Hwj chim hauv Tebchaws Europe).
Cov qauv nta:
Cov rwb thaiv tsev nyuaj (muaj cov ntaub ntawv rwb thaiv tsev lossis cov roj rwb thaiv tsev).
Advanced xyuas cov tshuab (xws li faib tawm kub sensing) thiab anti electromagnetic cuam tshuam tshuab yuav tsum tau ua.
