Kev tsom xam ntawm Hluav taws xob tsheb npav bar: cov ntaub ntawv, yam ntxwv, kev siv, thiab cov lus teb rau cov lus nug tseem ceeb

Hauv kev lag luam hluav taws xob, kev xaiv ntawm Grounding tooj liab busbars yog ua raws siab -purity tooj liab, thiab cov qib tseem ceeb tau muab faib ua ob pawg: T2 electrolytic tooj liab thiab TU1 / TU2 oxygen dawb tooj liab. Ntawm lawv, T2 electrolytic tooj liab muaj ib tug purity ntawm tsis tsawg tshaj li 99.90%, tus nqi zoo heev -effectiveness, thiab yog cov feem ntau lug siv qeb, haum rau feem ntau scenarios xws li busbar, busbar, Earthing davhlau ya nyob twg tooj liab busbar cov khoom, thiab lwm yam. TU1/TU2 oxygen dawb tooj liab tsom rau qhov kub tsis tshua muaj zog, siab voltage 1} hluav taws xob cables, thiab siab - cov khoom siv zaus nrog kev ua haujlwm siab dua.

Daim ntawv ntawm Ground bus bar yog muab faib ua cov mos mos thiab tawv. Mos lub xeev ntshav tooj liab muaj ductility zoo tom qab annealing kev kho mob thiab yog siv rau cable cores thiab muag kev sib txuas; Cov tooj liab tawv tawv, tom qab ua haujlwm txias, muaj lub zog siab thiab siv rau cov khoom siv hluav taws xob thiab cov khoom siv nyuaj. Tsis tas li ntawd, tooj liab busbar, tseem hu ua tooj liab busbar, yog ib tug neeg xyuas pib nrog tus ntoo khaub lig -section. Nws lub luag haujlwm tseem ceeb yog txhawm rau sau cov khoom siv hluav taws xob tseem ceeb tam sim no thiab hloov mus rau ntau yam ceg, ua kom yooj yim ntawm cov xaim hauv lub txee faib khoom, thiab pab tswj xyuas tom qab. Nws cov xim saum npoo muaj cov qauv kev lag luam meej thiab sib haum rau cov kab sib txawv, uas yog lub cim tseem ceeb los xyuas kom muaj kev nyab xeeb ntawm hluav taws xob.
 

Txawm hais tias lub zog xa hluav taws xob tsheb npav muaj qhov ua tau zoo heev, nws yog qhov ua rau muaj kev cuam tshuam nrog oxygen thiab sulfides thaum raug huab cua ntev, tsim cov txheej txheem oxide, ua rau muaj kev tiv thaiv, thiab ua rau cov cua sov hauv zos. Yog li ntawd, nws yog ib qho tsim nyog yuav tau xaiv txoj kev kho saum npoo kom tsim nyog raws li kev siv scenario. Cov tooj liab liab liab yuav tsum tsis muaj kev kho mob thiab muaj qhov ua tau zoo tshaj plaws ntawm kev ua kom sov, tab sis muaj kev tiv thaiv corrosion tsis zoo thiab tsuas yog tsim rau luv luv - siv rau hauv qhov chaw qhuav thiab huv hauv tsev. Tin plating yog txoj kev kho mob uas siv dav tshaj plaws, thiab cov txheej txheej tin tuaj yeem cais cov huab cua zoo, tiv thaiv tooj liab substrate oxidation, thiab txhim kho corrosion kuj. Txawm li cas los xij, cov thermal conductivity ntawm tin yog qis dua li ntawm tooj liab, uas yuav cuam tshuam rau cov cua sov dissipation rau qee yam.

Silver plated Backplane tsheb npav bar muaj qhov ua tau zoo tshaj plaws. Silver muaj cov conductivity zoo heev thiab thermal conductivity, uas muaj peev xwm sib npaug ntawm cov cua kub dissipation kom zoo dua ntawm tooj liab tuav nrog ruaj khov tiv thaiv. Nws yog feem ntau siv nyob rau hauv qhov tseem ceeb xws li siab -kawg hluav taws xob tiv tauj, tab sis tus nqi siab thiab daim ntawv thov ntau yam tsawg. Qhov taw qhia tseem ceeb rau kev txiav txim siab cov cua kub dissipation ntawm tooj liab tuav yog qhov kub thiab txias, uas yuav tsum nruj me ntsis ua raws li cov kev cai ntawm lub teb chaws tus qauv GB7251.1 kom tsis txhob muaj kev nyab xeeb kev nyab xeeb tshwm sim los ntawm kub nce siab.

Thaum txuas cov tooj liab cov khoom thauj mus rau lub thav duab Circuit Court breaker, cov lus qhia tshwj xeeb yuav tsum tau ua raws li nruj me ntsis, thiab txhua qhov kev nthuav dav muaj feem xyuam rau kev nyab xeeb ntawm lub zog hluav taws xob.

Ua ntej, nws yog ib qho tsim nyog los qhia meej txog txoj kev nkag thiab tawm. Txawm hais tias nws yog los ntawm sab saum toj mus rau hauv qab los yog los ntawm sab laug mus rau sab xis, nws yuav txiav txim siab tag nrho cov kev taw qhia ntawm cov tooj liab tuav thiab layout nyob rau hauv lub txee, uas yuav tsum tau txiav txim nyob rau hauv thaum ntxov theem ntawm tsim.

Qhov thib ob, nws yog ib qho tsim nyog yuav tsum nruj me ntsis tswj cov theem theem thiab N-theem txoj hauj lwm. Cov theem A, B, thiab C theem ntawm peb -theem hluav taws xob yuav tsum tsis txhob tsis meej pem, txwv tsis pub nws yuav ua rau muaj teeb meem loj xws li lub cev muaj zog rov qab. Txoj hauj lwm ntawm txoj kab nruab nrab thiab seb sab nraub qaum puas yuav tsum tau ua kom pom tseeb.

Nyob rau tib lub sijhawm, cov lus qhia tshwj xeeb ntawm Vertical tooj liab bonding busbar yuav tsum ua raws li cov khoom nqa tam sim no, thiab cov hluav taws xob tshem tawm thiab kev nkag mus deb ntawm cov tooj liab nyob thiab nruab nrab ntawm cov tooj liab thiab cov khoom hauv av yuav tsum ua raws li lub teb chaws cov qauv los tiv thaiv huab cua tawg thiab arc tiam. Tsis tas li ntawd, kev xuas nrig ntaus ntawm tooj liab tuav yuav tsum yog qhov tseeb, thiab qhov chaw ntawm lub qhov, txoj kab uas hla, thiab cov qauv yuav tsum tau ua raws li qhov yuav tsum tau ua. Thaum kawg, nws yog ib qho tsim nyog yuav tsum tau ua kom paub meej cov txheej txheem ntawm cov khoom siv tooj liab tawm kom ntseeg tau tias kev sib txuas zoo nrog cov cables sab nraud thiab cov busbars.

Lub installation ntawm Tinned tooj liab hauv av bar rau underground system nyob rau hauv lub computer chav tsev yuav tsum nruj me ntsis raws li cov txheej txheem txheej txheem thiab cov ntsiab lus tshwj xeeb kom ntseeg tau tias kev ua haujlwm txhim khu kev qha hauv av. Kev tsim kho yuav tsum tau ua raws li "Kev Npaj Kev Tsim Kho → Grounding Device Installation → Downlead Installation → Lightning Protection Belt Support Installation → Lightning Protection Network Laying → Grounding Resistance Test". Cov ntaub ntawv siv yuav tsum ua raws li cov kev qhia tshwj xeeb ntawm GB50169-2006, thiab tag nrho cov welds yuav tsum muaj tag nrho thiab tsis muaj qhov tsis xws luag nrog kev tiv thaiv corrosion.

Yog hais tias cov qauv steel tuav tau siv rau tus neeg xyuas pib ntawm Grounding busbar Tmgb tooj liab, qhov ntev ntawm qhov vuam seam yuav tsum tsis pub tsawg tshaj 6 npaug ntawm txoj kab uas hla ntawm cov hlau bar. Txoj hlua tiv thaiv xob laim yuav tsum tau ua los ntawm 25 × 4mm kub-dip galvanized ca steel, thiab qhov sib nrug ntawm kev txhawb nqa yuav tsum tsis pub tshaj 1.5m. Kev siv hluav taws xob hauv av yuav tsum siv cov txheej txheem xws li TT, TN-C-S, TN-S, thiab lwm yam. Lub tshuab hluav taws xob siab thiab qis qis yuav tsum tau nruab nrog 300mm siab grounding rings, thiab tag nrho cov khoom hlau yuav tsum tau txuas nrog equipotential. Kev tiv thaiv hauv av yuav tsum tau sim nrog cov cuab yeej tshwj xeeb kom ua tau raws li tus qauv, ua kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm lub cev.

Yog tias koj muaj ib qho kev yuav khoom, kev sib tham, lossis kev teeb tsa ntsig txog kev xav tau rauGrounding tooj liab busbars, thov koj xav tiv tauj peb txhua lub sijhawm. Peb yuav muab cov kev daws teeb meem tshaj lij thiab siab - cov kev pabcuam zoo raws li koj qhov xwm txheej tiag tiag. Peb tos ntsoov rau koj qhov kev nug.
