1. Lub tshav kub dissipation kev ua tau zoo ntawm lub tsheb npav yog qhov zoo. Cov khoom siv insulating ntawm cable (cov tub ntxhais hlau rwb thaiv tsev thiab cov rwb thaiv tsev sab nrauv) yog ob qho tib si cov khoom siv insulating thiab cov khoom siv cua sov. Yog li ntawd, thaum lub hwj chim cable muab tso rau hauv tus choj, qhov siab tshaj plaws ntawm 2 txheej tau tso cai. Yog vim li cas yog xav txog thaum tshav kub kub dissipation. Lub busway siv cua conduction kom dissipate tshav kub, thiab dissipates tshav kub los ntawm steel plhaub nyob rau hauv kev sib cuag. Yog li ntawd, nws cov cua kub dissipation kev ua tau zoo yog piv rau cov cable, thiab cov cua kub dissipation kev ua tau zoo ntawm cov cable yog pom tseeb.
2. Yuav luag tsis muaj kev tu lub tsheb npav. Kev saib xyuas txhua hnub feem ntau yog ntsuas qhov ntsuas kub ntawm lub casing thiab lub grommet bolt, qhov kub thiab txias ntawm qhov sib koom ua ke ntawm lub thawv tuaj, thiab lwm yam. Yog hais tias lub grommet bolt yog qib 4.8, nws yuav tsum tau nruj nreem. Yog siv qib 8.8. High-strength bolts tsis tas yuav tsum tau nruj nreem. Txawm li cas los xij, lub cable raug txwv los ntawm cov yam ntxwv xws li hnav yooj yim, kev laus, thiab lub neej luv luv vim nws cov khoom siv, yog li nws yuav tsum tau kuaj xyuas thiab khaws cia tsis tu ncua, thiab txawm hloov.
3. Cov khoom nqa tam sim no. Tam sim no, lub cable tsuas tuaj yeem ua tiav qhov siab tshaj plaws ntawm ntu ntu ntawm 1000mm thiab ntsuas tam sim no ntawm 1600A. Txawm li cas los xij, qhov loj-loj cable no tsis tshua muaj siv hauv cov ntawv thov thiab cov haujlwm vim nws qhov loj thiab qhov hnyav. Hauv engineering, 400 mm thiab cov lus qhia hauv qab no yog siv rau kev faib hluav taws xob, uas yuav tsum muaj ntau cov cables los muab lub zog rau tib lub sijhawm. Qhov siab tshaj plaws tam sim no ntawm lub busbar tuaj yeem ncav cuag 6300A, thiab nws lub peev xwm nqa tam sim no tsis sib haum los ntawm cov cables.
4. Lub peev xwm dhau ntawm lub tsheb npav muaj zog. Nws nyob ntawm qhov ua haujlwm kub ntawm cov khoom siv insulating siv rau nws. Cov khoom siv insulating siv rau lub tsheb npav yog overstretched siv cov khoom siv nrog kev ua haujlwm kub ntawm 105 ° C. Radiation cross-linking nrog kev ua haujlwm kub ntawm ntau tshaj 140 ° C tau tsim. Flame Retardant Wrap Tape (PER) thiab Radiation Crosslinked Polyhydrocarbon Thaum tshav kub kub Shrinkable Tubing. Qhov kub thiab txias ua haujlwm ntawm cov khoom siv insulating siv nyob rau hauv cable feem ntau yog 95 degree thiab 105 degree, yog li lub peev xwm tshaj ntawm lub busbar yog ntau dua li ntawm cov cable.
5. Lub tsheb npav duct yog yooj yim rau kais. Lub npe hu ua plug-in bus duct txhais tau hais tias nws siv txoj kev plug-in los coj mus rhaub cov khoom siv hluav taws xob ntawm cov kab tseem ceeb mus rau cov ceg kab, thiab muaj cov thawv ntsaws ntsaws ntsaws rau txhua ob peb meters, yog li tus kais dej tau yooj yim heev. . . Lub cable yuav tsum tau tapping rau ntawm qhov chaw, uas muaj kev ntseeg tsis zoo. Txawm tias cov ceg ntoo prefabricated muaj qhov tshwj xeeb tsis zoo, feem ntau vim tias nws yuav tsum tau kho rau lub Hoobkas. Txoj kev txuas ceg txuas tau txais qhov qhib "C" hom hoop. Hoop zog? Tsis tas li ntawd, tus nqi ntawm txhua ceg taub hau yog kim, yog li cov ceg ntoo prefabricated cable tseem tsis tau siv dav. Txhua lub hauv pem teb yuav tsum tau txiav tawm lub hwj chim, thiab lub tsheb npav tsis tas yuav tsum tau siv hluav taws xob, tsuav yog lub thawv ntsaws ntawm lub tsheb npav raug tshem tawm hauv qhov tsis muaj kev thauj khoom. Tab sis txhawm rau txiav tawm ceg fais fab ntawm cov ceg ntoo prefabricated, nws yog qhov txaus ntshai heev rau kev khiav lag luam nyob rau hauv cov ntaub ntawv ntawm lub zog nyob.
6. Lub tsheb npav tuaj yeem tiv thaiv kev sib tsoo thiab hluav taws. Thaum Lub Yim Hli 27, 2000, qhov teeb meem Moscow Ostankino TV Ntauwd hauv Russia, lub tsev siab thib ob hauv ntiaj teb thiab lub tsev siab tshaj plaws hauv Tebchaws Europe, tau hlawv hluav taws loj. Yog vim li cas yog tias lub cable yog overloaded; Baosteel peb lub converters nres ntau lawm, uas kuj yog tshwm sim los ntawm hluav taws xob cable. Cov txheej txheej insulating thiab cov tawv nqaij ntawm cov kab hluav taws xob zoo tib yam yuav kub hnyiab tau, thiab cov nplaim hluav taws xob kuj tseem yuav hlawv hauv qab nplaim taws. Lawv yuav tsis hlawv kom txog thaum nplaim taws tawm mus. Hluav taws kub-resistant cables yuav tsis hlawv, tab sis lawv kim heev. kab. Sab nrauv ntawm lub busbar yog hlau thiab yuav tsis hlawv. Txawm hais tias cov khoom siv insulating ntawm cov tooj liab kub kub, cov nplaim taws yuav tsis khiav mus rau sab nraud ntawm lub busbar.
