Kev tsom xam ntawm av tooj liab tsheb npav bar kev lag luam kev paub

Grounding bar qhov yog cov khoom siv tseem ceeb hauv kev tsim hluav taws xob engineering, feem ntau yog siv rau cov khoom siv hauv av sau. Nws lub luag haujlwm tseem ceeb yog txhawm rau tiv thaiv av muaj peev xwm tiv thaiv kev sib tsoo, ua tiav kev tiv thaiv hluav taws xob sib npaug, thiab muab kev lees paub rau kev ua haujlwm nyab xeeb ntawm lub zog hluav taws xob. Nws yog feem ntau deployed los ntawm lub computer chav tsev mus rau pem hauv ntej kawg ntawm lub hauv av daim phiaj, tsim ib tug equipotential siv los ntawm kev sib txuas cov static pem teb voltage vaj huam sib luag nplhaib los yog lub tis system grounding bar. Cov lus qhia tshwj xeeb muaj xws li kev sib txuas lus- tshwj xeeb 400 * 120 * 6mm tooj liab tuav, 20 cua busbars (400 * 120 * 6mm), thiab lwm yam.

Hauv kev tsim hluav taws xob hluav taws xob, daim ntawv thov ntawm tooj liab cov tsheb npav rau cov tshuab hauv av yuav tsum ua raws li cov kev cai tseem ceeb, xws li "Cov Ntsiab Lus Tseem Ceeb rau Kev Tiv Thaiv Kev Nyab Xeeb Kev Tiv Thaiv Kev Tiv Thaiv thiab Kev Nyab Xeeb Tsis Siv Neeg" thiab kev txhim kho kev ntsuas rau siab -frequency channels ntawm relay tiv thaiv tawm los ntawm National Research Center xyoo 1998, uas kom meej meej yuav tsum muaj kev tiv thaiv hauv av thiab kev sib txuas ntawm cov chaw sib txuas. Txawm li cas los xij, hauv kev tsim kho tiag tiag, muaj qhov sib txawv hauv cheeb tsam hauv kev kho txoj hauv kev ntawm Earthing davhlau ya nyob twg tooj liab busbar cov khoom siv thiab cov naj npawb ntawm cov ntsiab lus tseem ceeb hauv kab sib txuas. Tsis tas li ntawd, txheej thaiv cable yuav tsum tau muab tso rau hauv ob lub ntsiab lus raws li tus qauv los cuam tshuam cov electromagnetic cuam tshuam, thaum kev sib txuas lus tsis muaj zog tam sim no cov teeb liab cables siv ib qho - taw tes hauv av kom ruaj ntseg ntawm cov khoom siv ua haujlwm.

Hauv cov chaw tsim hluav taws xob thiab cov chaw ua haujlwm substations, txhawm rau ua kom muaj kev nyab xeeb ntawm cov khoom siv thiab cov neeg ua haujlwm, yuav tsum tau npaj cov phiaj xwm hauv av uas npog tag nrho cov nroj tsuag lossis chaw nres tsheb. Tag nrho cov khoom siv tseem ceeb thiab theem nrab yuav tsum tau txuas nrog rau daim phiaj hauv av. Muaj ntau qhov xwm txheej loj hauv lub zog hluav taws xob muaj feem cuam tshuam nrog kev ua haujlwm ntawm daim phiaj hauv av thiab kev sib txuas ntawm cov khoom siv hauv av. Cov kev cai tseem ceeb ntawm lub tsheb npav hauv av bar hluav taws xob vaj huam sib luag yog qhov tseem ceeb hauv ob yam: qhov sib txawv ntawm qhov sib txawv hauv lub network thiab cov kev qhia tshwj xeeb. Thaum ib qho -theem luv luv Circuit Court yog grounded nyob rau hauv lub chaw nres tsheb, vim tsis muaj peev xwm ntawm grounding kuj yog xoom, luv luv -circuit tam sim no yuav ua rau muaj peev xwm tsis sib xws ntawm lub grounding network. Qhov deb ntawm qhov luv luv -circuit grounding point, qhov sib txawv ntawm qhov voltage ntau dua, uas tuaj yeem ua rau cov khoom siv rwb thaiv tsev puas tsuaj, ua rau muaj kev cuam tshuam, thiab txawm tias kub hnyiab cables lossis lub thawv davhlau ya nyob twg.

Nyob rau hauv cov nqe lus ntawm kev specifications rau tooj liab hauv pem teb tsheb npav tuav, tus thawj "Technical Code for Grounding Design of Power Equipment" (SDJ8-79) muaj qhov yuav tsum tau meej rau grounding kuj ntawm nruab nrab point ncaj qha grounding systems. Hauv cov cheeb tsam uas muaj av tiv taus siab, qhov kev tiv thaiv tuaj yeem so mus rau 5 Ω, tab sis qhov kev sib cuag thiab cov kauj ruam muaj peev xwm yuav tsum tau txheeb xyuas. Tom qab kev tsim kho, lub peev xwm faib nkhaus yuav tsum tau ntsuas thiab kos. Nrog rau qhov nce ntawm lub zog hluav taws xob muaj peev xwm, kev saib xyuas ntau dua yog them rau kev tswj cov av tiv thaiv qis dua 0.5 Ω hauv engineering, thiab kev ntsuas hluav taws xob sib npaug tau coj los ua kom muaj peev xwm sib npaug hauv kev tiv thaiv ntau yam.

Tam sim no, cov khoom siv thib ob feem ntau tau ua tiav kev siv computer, uas yuav tsum muaj qhov chaw ua haujlwm zoo thiab muaj peev xwm tiv taus qhov chaw hnyav xws li electromagnetic cuam tshuam, cuam tshuam overvoltage, thiab voltage nce hauv daim phiaj hluav taws xob. Yog li ntawd, cov teeb meem hauv av yog qhov tseem ceeb tshwj xeeb, feem ntau muab faib ua tsib pawg: kev nyab xeeb hauv av.

Rau kev txiav txim siab txog kev nyab xeeb ntawm tus kheej, cov khoom siv thib ob thiab cov khoom siv plhaub hauv lub txee yuav tsum tau muab tso rau hauv cov tooj liab busbar rau cov khoom siv hluav taws xob tsis cuam tshuam hauv lub vijtsam los ntawm cov xaim hauv av. Nrog kev pab ntawm channel steel brackets thiab tiaj tus steel sib txuas, txhua yam khoom siv tuaj yeem txuas rau hauv av kab sib chaws; Kev cog lus hauv av yuav tsum tau txuas cov kev sib txuas hauv av uas muaj peev xwm sib txuas ntawm cov khoom siv thib ob (tshwj xeeb yog cov cuab yeej txawv teb chaws) rau hauv av bar hauv qhov screen, thiab feem ntau, synchronously txuas cov cuab yeej casing yog xav tau.

Txhawm rau kom muaj kev nyab xeeb ntawm tus kheej thiab cov cuab yeej siv, lub hauv paus ntawm analog circuits yuav tsum tau grounding TA thiab TV circuits ntawm ib qho chaw. TVs lossis TAs uas muaj hluav taws xob txuas rau ib leeg yuav tsum tau muab tso rau hauv ib qho chaw hauv chav tswj, thaum cov hluav taws xob ywj pheej feem ntau yog grounded ntawm ib qho chaw ntawm qhov chaw; AC fais fab hauv av yuav tsum tau siv cov kev sib cais transformers los tiv thaiv cov cuab yeej los ntawm kev cuam tshuam los ntawm xob laim lossis kev khiav hauj lwm overvoltage. Cov cuab yeej siv hluav taws xob thiab kev sib txuas lus tuaj yeem ua qhov tseem ceeb ntawm DC fais fab mov kom txo tau UPS lub zog teeb tsa thiab kev saib xyuas siab.

Cov xaim hauv av ntawm lub tshuab luam ntawv fais fab mov hauv qhov screen yuav tsum tsis txhob txuas nrog lub tsheb npav tooj liab tapping rau hauv lub vijtsam kom tsis txhob cuam tshuam; Lub grounding ntawm cable shielding txheej yuav tsum tau sib txawv raws li qhov sib txawv scenarios. Cov kab hluav taws xob txuas cov khoom siv tseem ceeb thiab cov khoom siv thib ob yuav tsum tau muab tso rau ntawm ob lub ntsiab lus, thaum cov cables uas tsis muaj zog tam sim no analog teeb liab yuav tsum tau grounded ntawm ib qho chaw.

Tam sim no, muaj ntau yam tsis yog - tus qauv kev coj ua hauv kev teeb tsa lub zog xa hluav taws xob hauv cov chaw nres tsheb fais fab thiab cov chaw nres tsheb hauv ntau lub xeev thiab lub nroog: qee qhov txuas cov kab hauv av hauv txhua qhov kev tiv thaiv nrog cables, qee qhov ncaj qha tso cov tooj liab tuav ntawm cable txhawb lossis rivet lawv nrog rivets, qee qhov tsuas txuas ob kawg ntawm cov tooj liab tuav rau hauv av ncaj qha rau hauv av, qee qhov txuas ncaj qha rau hauv av. ntawm - qhov chaw davhlau ya nyob twg lub thawv rau cov tooj liab tuav hauv lub cable trench. Nws tsis paub meej tias cov tooj liab tuav hauv qhov hloov pauv thiab chav tswj kev tiv thaiv yuav tsum tau txuas nrog, thiab txawm tias muaj kev xav tsis zoo tias "tsis muaj siab- tiv thaiv zaus, tsis tas yuav nteg tooj liab tuav".

Hauv kev teb rau cov teeb meem no, nws yog ib qho tsim nyog los qhia meej cov ntsiab lus tseem ceeb ntawm Backplane bus bar installation: nruj me ntsis raws li cov qauv kev lag luam, xaiv cov txheej txheem ruaj khov thiab cov ntsiab lus sib txuas tsim nyog raws li qhov tseeb ntawm qhov chaw, thiab ntsuas qhov sib npaug ntawm qhov sib npaug thiab kev tsim qauv; Ua tib zoo saib xyuas cov kev tswj ntawm kev tiv thaiv hauv av thiab qhov sib npaug ntawm qhov muaj peev xwm xa tawm kom tsis txhob muaj av tsis ua haujlwm los ntawm kev tsim kho tsis raug; Paub qhov txawv ntawm cov kev cai hauv av ntawm cov khoom siv sib txawv thiab cov cables, tshem tawm cov teeb meem cuam tshuam, ua kom muaj kev ruaj ntseg thiab kev ntseeg tau ntawm cov av hauv av, thiab nteg lub hauv paus ruaj khov rau kev ua haujlwm ruaj ntseg ntawm lub zog hluav taws xob. Xiamen Apollo Stamping Vuam Technology Co., Ltd muaj kev koom tes nrog cov khoom siv fais fab, tshwj xeeb hauv Copper grounding bus bar khoom. Cov khoom no nruj me ntsis ua raws li cov qauv kev lag luam thiab cov kev cai uas tau hais los saum toj no, thiab tuaj yeem hloov mus rau ntau qhov xwm txheej xws li fais fab nroj tsuag thiab substations, muab kev txhawb nqa txhim khu kev qha rau hauv av.

Yog tias koj muaj kev xav tau ntawm kev yuav khoom, kev sab laj kev lag luam lossis kev xav tau kev cai rauCov tsheb npav tooj liab hauv av, thov koj xav tiv tauj peb. Peb yuav muab cov kev daws teeb meem tshaj lij thiab cov khoom lag luam siab - cov kev pabcuam zoo raws li koj qhov xwm txheej tiag tiag, thiab tos ntsoov yuav ua haujlwm ua ke nrog koj kom yeej- yeej qhov xwm txheej.
