Tsim Kev Tiv Thaiv Kev Tiv Thaiv Hluav Taws Xob hauv Network Computer Room 1. Kev tiv thaiv xob laim tsim Kev tiv thaiv xob laim hauv av yog ib qho tseem ceeb subsystem rau kev tiv thaiv tsis muaj zog tam sim no cov cuab yeej precision thiab cov cuab yeej chav, uas feem ntau ua kom muaj kev ntseeg siab ntawm cov khoom siv thiab tiv thaiv kev puas tsuaj ntawm xob laim. Lub network center computer chav tsev yog ib qho chaw uas muaj nqi heev. Thaum xob laim tshwm sim, nws yuav ua rau muaj kev poob nyiaj txiag tsis txaus thiab cuam tshuam rau kev sib raug zoo. Raws li cov kev cai cuam tshuam ntawm IEC61024-1-1 tus qauv, kev tiv thaiv xob laim ntawm chav tsev hauv nruab nrab ntawm lub khoos phis tawj yuav tsum tau teeb tsa ua ob chav qauv tsim. Tam sim no, chav faib hluav taws xob tseem ceeb ntawm lub tsev muab kev tiv thaiv hluav taws xob thawj zaug raws li lub tsev tiv thaiv hluav taws xob tsim tshwj xeeb. ntaus ntawv). Lub surge protector txais ib qho kev ywj pheej module thiab yuav tsum muaj lub tswb tsis ua hauj lwm. Thaum lub module raug ntaus los ntawm xob laim thiab ua tsis tiav, lub module tuaj yeem hloov tau ib leeg yam tsis tau hloov tag nrho cov surge protector. Lub ntsiab tsis thiab ntsuas ntawm lub thib ob thiab tertiary composite xob laim ntes: ib theem txaus: ≥40KA (8/20μs), lub sijhawm teb: ≤ 25 ns 2. Grounding system tsim Chav tsev hauv computer yuav tsum muaj plaub yam nram qab no: DC hauv av ntawm lub computer system, AC ua haujlwm hauv av, AC tiv thaiv av thiab hauv av tiv thaiv xob laim. Qhov kev tiv thaiv ntawm txhua qhov grounding system yog raws li nram no: 1. Lub DC grounding kuj ntawm cov khoom siv hauv computer tsis ntau tshaj 1Ω. 2. Cov av tiv thaiv ntawm AC tiv thaiv hauv av yuav tsum tsis txhob siab tshaj 4Ω; 3. Kev tiv thaiv hauv av ntawm kev tiv thaiv hauv av yuav tsum tsis txhob siab tshaj 10Ω; 4. Lub grounding kuj ntawm AC chaw ua hauj lwm yuav tsum tsis txhob ntau tshaj 4Ω; Kev tiv thaiv xob laim thiab hauv av ntawm chav tsev khoom siv network kuj suav nrog: 1. Equipotential kev sib txuas hauv chav tsev khoom Lub nplhaib-shaped grounding busbar tau teeb tsa hauv chav tsev khoom siv network. Cov khoom siv thiab chassis hauv cov khoom siv hauv chav tsev yog txuas nrog rau hauv av busbar nyob rau hauv daim ntawv ntawm S-type equipotential kev twb kev txuas, thiab yog nteg nyob rau hauv lub txhawb nqa pem teb nrog 50 * 0.5 tooj liab-platinum strips. 1200 * 1200 daim phiaj, tso 30 * 3 (40 * 4) tooj liab tapes nyob ib ncig ntawm chav tsev khoom. Cov tooj liab tapes yog nruab nrog tshwj xeeb grounding terminals. Tag nrho cov ntaub ntawv hlau nyob rau hauv cov khoom siv chav tsev yog grounded nrog braided mos tooj liab xov hlau thiab txuas nrog lub tsev. tiv thaiv av. Tag nrho cov xaim hauv av (xws li cov khoom siv, cov khoom tiv thaiv hluav taws xob, cov hlau troughs, thiab lwm yam) thiab cov hlau hlau troughs hauv qhov project yuav tsum luv luv, tiaj tus thiab ncaj, thiab cov av tiv thaiv yuav tsum tsawg dua lossis sib npaug li 1 ohm. 2. Computer chav shielding tsim Lub shielding ntawm tag nrho cov khoom siv chav tsev yog hexahedral shielding nrog cov xim hlau daim hlau. Lub shielding phaj yog welded seamlessly ua ntej, thiab lub shielding lub cev ntawm phab ntsa yog grounded ntawm tsis muaj tsawg tshaj li 2 qhov chaw nrog lub grounding busbar ntawm txhua sab. 3. Tsim cov khoom siv hauv av hauv chav computer Vim tias qhov kev xav tau hauv av siab heev ntawm chav tsev network, ib qho khoom siv hauv av tau ntxiv nyob ze ntawm lub tsev, thiab 15 galvanized lub kaum sab xis steels tau tsav mus rau hauv daim phiaj hauv av, welded nrog cov hlau tiaj tus, thiab rov qab nrog cov neeg sawv cev tiv thaiv. Lub hauv paus zoo li qub ntawm cov khoom siv chav tsev yog qhia los ntawm 50mm² multi-strand tooj liab tub ntxhais hlau.
