- Cov chav siab nyem: Chav hloov hluav taws xob yuav tsum muaj cov tshuaj tua hluav taws muaj thaum muaj xwm ceev thiab cov kev thaiv kom tiv thaiv cov roj kub.
- Hluav taws kub hluav taws xob systems: Cov hluav taws xob loj yuav tsum muaj tshuaj tsuag dej, ua npuas ncauj, lossis cov roj ntws thiab cov tshuaj nitrogen.
2. GB 50148 (Tus lej rau kev tsim kho thiab kev lees txais cov cuab yeej hluav taws xob teeb tsa: Cov Hluav Taws Xob Hluav Taws Xob)
- Cov peev txheej teeb tsa: Cov hauv paus hloov pauv yuav tsum yog txhawb kom tiv thaiv kev nyab xeeb; Roj ntim cov chaw (piv txwv li, pits, kav dej) yuav tsum ntsib cov qauv hluav taws kub.
3. DL / T 5218 (Cov Qauv Txuj Ci rau Tsim ntawm 220KV-750kV Hloov)
- Yuam kev firewalls lossis hluav taws xob-tiv thaiv kev hloov pauv ntawm cov roj-cov pa hluav taws xob sib hloov pauv ntawm cov chaw, nrog kev nyab xeeb nyob nruab nrab ntawm ntau pawg.
III. Kev Tiv Thaiv Hluav Taws Kub Kev Ntsuas thiab Kev Xav Tau
1. Kev sib cais hluav taws thiab txheej txheem
- Ua kom muaj kev nyab xeeb ntawm kev hloov pauv, cov tuam tsev, thiab lwm yam khoom siv (feem ntau 5-15 metres, nyob ntawm cov roj ntim).
- nruab pob hluav taws los yog kev thaiv ntawm ntau cov hloov pauv (qhov siab ntau dua lossis sib npaug rau cov roj conservator qib).
2. Kev siab siab thiab cov khoom siv roj
- Muab cov roj kub kom xwm txheej ceev lossis lub pits nrog lub peev xwm ntau dua lossis sib npaug rau 110% ntawm cov roj transformer.
- Cov roj av nrog cov roj ua kom hloov roj kom hloov cov roj kom muaj kev nyab xeeb cov cheeb tsam thaum hluav taws.
3. Hluav taws kub hluav taws xob
- Tsis siv neeg cov dej tshuaj tsuag: ua haujlwm los ntawm cov ntsuas kub lossis cov pa taws, npog lub cev hloov pauv thiab cov roj conservator.
- Cov kua dej thiab cov roj nitrogen tso tawm: ntws roj thiab txhaj nitrogen mus rau txhawm rau txhawm rau txhawm rau txhawm rau tshem tawm kev sib txuas.
- Ua npuas ncauj tua hluav taws tshuab: haum rau roj hluav taws xob (yuav tsum muaj kev nyab xeeb ntawm kev hloov pauv).
- Portable tua hluav taws tua hluav taws: Tso hmoov nplej qhuav lossis sib sau ua ke ze hloov pauv.
4. Saib xyuas thiab tswb
- Nruab cov roj Relays (Lub Ncauj Roj Alarms, cov pa roj hnyav), cov pa roj hnyav), thiab cov nplaim taws.
- Sib xyaw nrog lub tswb hluav taws kub rau kev saib xyuas tiag tiag.
5. Cov ntaub ntawv tua hluav taws thiab cov qauv
- Siv phab ntsa hluav taws xob tua hluav taws (ntau dua lossis sib npaug rau 2- cov rooj hluav taws tsis kam ntaus nqi) thiab cov nplaim hluav taws hauv cov chav hloov.
- Foob cable trenches thiab cov yeeb nkab nkag mus nrog cov hluav taws xob fireproof.
IV. Kev Ua Haujlwm thiab Kev Saib Xyuas
1. Nquag xyuas cov roj roj, ntsuas kub, thiab muab cov ntsaws ruaj ruaj los tiv thaiv kom tsis txhob muaj cov dej xau.
2. Cov khoom siv ntshiab hluav taws xob (piv txwv li, cov nroj, khib nyiab) ib ncig ntawm cov hloov pauv thiab ua kom muaj hluav taws kub.
3. Kuaj hluav taws kub roj teeb thiab lub tswb txhua xyoo thiab kev ua haujlwm hnyav.
V. QHOV TSEEB
- Cov chaw hloov hauv av: txhim kho tshuab cua thiab ua pov thawj kev tsim los tiv thaiv cov roj sib tw.
- Cov chaw pheej hmoo siab: Siv nplaim taws-retardant insulating roj (piv txwv li -Fluid) lossis cov tshuab hloov cua qhuav yog cov hloov pauv.
