Hauv hluav taws xob Engineering, kev teeb tsa kev teeb tsa rau kev faib cov xov hlau hluav taws xob cov xov hlau cuam tshuam nrog cov cuab yeej thiab cov neeg ua haujlwm muaj kev nyab xeeb. Ua ke rau lub teb chaws tus qauv GB / T 7251.1-2023 nrog cov xwm txheej tseem ceeb, cov ntsiab lus tseem ceeb muaj raws li hauv qab no:
1. Grounding Tus Xaiv Tus Xaiv Tus Xaiv
Daj - Cov ntoo khaub ncaws siv, thiab cov kab ke uas seem yog suav tias yog qhov tsis muaj melting tsis muaj kev ua haujlwm dhau; NEEG KHO TSHUAB DUA YUAV TSUM TAU TXAIS LUB TSEV KHIAV KOOB ZOO TSHAJ PLAWS LOS NTAWM LUB CAIJ Nyob rau hauv ib qho haujlwm, kev siv tsis tau ntawm 2.5mm² hlau nyob rau hauv 16A Circuit Court tau tshwm sim hauv Rwb Thaiv Tsev Pa Hluav Taws Xob, qhia txog qhov tseem ceeb ntawm kev xaiv ua raws cai. Rau ib qho xwm txheej raug laij xam qauv, piv txwv li, thaum muaj lub peev xwm ntawm 40 degree, txoj kev nyab xeeb nqa tau cov peev xwm tam sim no (140A → 132A).
2. Cov Lus Qhia Txhim Kho
1) BRACKET Kev Ua Haujlwm: Cov kab xev yuav tsum tau sib txuas nrog rau ntawm phab ntsa, 250-300 hli los ntawm hauv av, thiab tswj kev sib tw ntawm 10-15 los ntawm phab ntsa.
2) Vuam Specifications: Ca hlau sib tshooj sib luag ntau dua lossis sib npaug ntawm 2 zaug dav dav dua lossis sib npaug rau 6 lub taub yuav tsum tau welded ntawm ob sab. Welds yuav tsum tau kho nrog kev tiv thaiv corrosion.
3) Crimping: Ntau - strand xov tooj yuav tsum yog crairped siv tooj liab lugs. Tus tuag yuav tsum ua raws li GB / T 14315-2008. Piv txwv li, ib txoj kev tuag hexagonal yuav tsum tau siv rau cov hlau xaim 35 mm² (indentation ntau dua lossis sib npaug rau 0.4 hli ntau dua. Tom qab poob paj, cov xov hlau yuav tsum dhau ib qho kev sim tensile.
4) Kev paub ntxiv txuas ntxiv: Lub txee thiab hauv av Busbar yuav tsum txuas nrog rau ntau lub ntsiab lus, nrog kev tiv taus tsawg dua lossis sib npaug ntawm 0.1 ω.
5) Cim cov cim tshwj xeeb: tag nrho cov cable yuav tsum tau pleev xim nrog daj- cov kab ntsuab ntsuab, thiab cov chaw yuav tsum raug sau tseg.
6) Cov xwm txheej tshwj xeeb: Ob chav hauv av ua haujlwm yuav tsum tau siv rau hauv qhov tawg {{}} Cov chaw pov thawj tsawg dua lossis sib npaug ntawm 4 ω.
3. Cov ntsiab lus lees paub
1) zais kev ua haujlwm: tsom rau kev tshuaj xyuas cov vuam zoo ntawm cov txee hauv qab thiab lub hauv paus channel hlau;
2) Cov khoom lag luam hluav taws xob: theem nrab Circuit Court yuav tsum txuas nrog cov chaw Busbar tseem ceeb;
3) Cov ntaub ntawv pov thawj: Tshawb xyuas tus neeg xyuas kev ua ntawv pov thawj thiab txheej tuab (piv txwv li zinc txheej ntau dua lossis sib luag rau 40μm);
4) Kev sim ua haujlwm: Ntxiv rau kev ntsuas txuas ntxiv, ib qho 2000V / 1min fais fab zaus nrog kev ntsuas voltage yog qhov yuav tsum tau ua.
4. Cov haujlwm tseem ceeb thiab kev tswj hwm cov ntsiab lus
1) Peb lub hlis twg tshuaj xyuas: sim cov hauv av tiv taus thiab tshawb xyuas qhov rooj Cumper xaim;
2) anti {{- corrosion kho: Thov anti anti- corrosion pleev xim rau cov khoom sab nraum zoov txhua ob xyoos, thiab txhua xyoo hauv cov ntug hiav txwv;
3) Kev Txawj Mob Txheej Txheem: Thaum muaj peev xwm nthuav dav ntau dua tus thawj tsim qauv muaj nuj nqis los ntawm 30%, lub av cable yuav tsum tau hloov kho ib txhij.
Cov txheej txheem txheej txheem txheem txheej txheem thiab siv cov txheej txheem {{0} Voj tswj kev tswj hwm ntawm txhua theem, los ntawm kev xaiv rau kev saib xyuas hluav taws xob muaj zog.
