- Kev nyiag tooj liab yog ib qho khoom siv hauv ntau cov peev nyiaj kho vaj tse, thiab CCS feem ntau tshem nws tawm,Vim tias ib txoj hlua bimetallic nrog lub plawv hlau yuav luag tsis muaj nqis muag dua, CCS grid tsis tsim nyog pheej hmoo ntawm kev nyiag.
Lub 40% IACS Benchmark: Vim li cas nws thiaj li tseem tshwm sim hauv Cov Lus Qhia Txog Kev Siv Hluav Taws Xob?
IACS sawv cev rau International Annealed Copper Standard, xyoo 1913 kev sib cog lus uas tau teeb tsa qhov conductivity ntawm cov tooj liab annealed lag luam li 100% thiab muab nws qhov resistivity ntawm 0.017241 Ω·mm² / m ntawm 20 ° C. Txhua tus lej conductivity hauv tsab xov xwm no - thiab txhua tus lej ntawm peb daim ntawv pov thawj zeb - yog feem pua ntawm qhov benchmark ntawd. Thaum ib qho kev qhia tshwj xeeb hu rau "40% IACS hlau," nws thov rau tus neeg coj hluav taws xob uas nws resistivity yog 0.017241 faib los ntawm 0.40, uas ua haujlwm tawm rau kwv yees li 0.0431 Ω·mm² / m. Kuv pom tias thaum cov neeg yuav khoom pom ib qho kev faib ntawd, tag nrho CCS-versus-tooj liab sib cav sib ceg dhau los ua lej es tsis yog kev lag luam.
Vim li cas 40% thiab tsis yog 30% lossis 21%? Hauv peb qhov kev paub txog kev xa khoom tawm, qib 40% tau dhau los ua qhov chaw siv hluav taws xob vim yog qhov laj thawj: nws yog chav kawm conductivity siab tshaj plaws uas cov hlau tooj liab clad ncav cuag hauv cov qib nyuaj-kos uas tau them los ntawmASTM B227(Qib 40 HS thiab Qib 40 EHS) thiab cov kev tsim kho uas raug khi ntawmASTM B228Yog tias koj nias siab tshaj 40% ces koj yeej xav tau cov tooj liab uas tuab dua li cov khoom siv uas nyuaj rub, thaum ntawd qhov sib txawv ntawm tus nqi piv rau cov tooj liab khov kho yuav nqaim sai.Vim tias qhov tuab ntawm cov cladding ua rau tus nqi ntawm cov khoom siv kim dua, tus neeg hlau CCS uas muaj cov khoom siv siab tshaj 40% IACS tsis yog lwm txoj hauv kev pheej yig dua li cov tooj liab khov.Kuv qhia cov pab pawg neeg yuav khoom kom suav 40% IACS ua lub qab nthab ntawm CCS pheej yig, thiab suav txhua yam uas siab dua li ntawd ua lub cim qhia kom tsuas yog teev tus nqi tooj liab khov kho xwb.
Kev Ua Tau Zoo ntawm Tooj Liab Clad Steel hauv Cov Grids Grounding tiag tiag: Koj Muab Ntau Npaum Li Cas?
Ntawm daim ntawv qhov sib txawv ntawm kev coj hluav taws xob zoo li phem heev: peb cov hlau tooj liab ntshiab kuaj ntawm 90% -99.9% IACS nrog kev tiv taus qis dua 0.017241 Ω·mm² / m, thaum peb CCS ntau yam khiav 15% -40% IACS. Hauv lub grid grounding, txawm li cas los xij, tus lej tseem ceeb tsis yog kev coj hluav taws xob hauv kev cais tawm - nws yog seb tus neeg coj hluav taws xob puas muaj sia nyob qhov txhaum tam sim no uas koj txoj kev kawm muab rau nws. IEEE 80, tus qauv feem ntau cov chaw pabcuam siv rau kev tsim qauv grid substation (IEEE Std 80), ntsuas cov neeg hlau los ntawm kev sib xyaw tam sim no thiab lub sijhawm, tsis yog los ntawm kev tiv taus ib leeg xwb. Thaum peb khiav tib yam 40 kA, 0.5-thib ob qhov txhaum los ntawm cov qauv fusing txheem, tus neeg hlau 40% IACS CCS xav tau kwv yees li 2.5 npaug ntawm qhov seem ntawm tooj liab kom ncav cuag tib qhov kev txwv thermal - qhov ntawd yog qhov hloov pauv ncaj ncees, thiab kuv sau nws rau hauv txhua qhov kev hais lus uas peb tshaj tawm.
Qhov 2.5 × factor ntawd zoo li yog qhov ua rau muaj kev sib cav sib ceg kom txog thaum koj teev tus nqi rau tag nrho cov khoom sib dhos. CCS ntawm lub cheeb loj dua tseem siv tooj liab tsawg dua los ntawm qhov hnyav,Vim tias lub plawv hlau nqa lub nra hnyav, tsuas yog xav tau ib txheej tooj liab 0.25 hli los ua qhov kev coj ua— thiab ntawm 60 Hz qhov zaus txhaum tam sim no cov neeg coob coob mus rau saum npoo av, uas yog qhov chaw uas tooj liab nyob. Peb pab neeg engineering tau coj ntau tus neeg yuav khoom los ntawm qhov kev sib cav txog daim tawv nqaij no nrog cov duab kos duab tiag tiag; thaum lawv pom tias txoj kev tam sim no thiab tooj liab nyob hauv tib lub nplhaib sab nraud, qhov kev tawm tsam conductivity feem ntau yuav mos.
Qhov uas kuv tsis pom zoo CCS yog qhov sib txawv heev: cov chaw me me hauv nroog uas qhov dav ntawm qhov av thiab qhov tob ntawm tus pas nrig raug kho thiab kev tshawb nrhiav qhov txhaum tsis muaj chaw rau kev loj dua tus neeg coj hluav taws xob. Hauv cov haujlwm ntawd peb hais peb cov hlau tooj liab ntshiab 99.97% yam tsis muaj kev thov txim.vimTsis muaj qhov zoo ntawm lub tshuab uas yuav pab tau rau qhov seem uas koj lub cev tsis haum. Tus neeg muag khoom uas thawb CCS mus rau hauv qhov xwm txheej ntawd yog muag khoom tawm tsam koj txoj kev tshawb nrhiav qhov txhaum, thiab kuv xav poob qhov kev txiav txim dua li kom lub grid ua haujlwm tsis zoo hauv xyoo thib peb.
