Idizayini ye-Lightning Protection Grounding System ku-Network Computer Room 1. Idizayini yokuvikela umbani Uhlelo lokumisa phansi lokuvikela umbani luyisistimu engaphansi ebalulekile yokuvikela imishini entekenteke yamanje namagumbi emishini, eqinisekisa ngokuyinhloko ukwethembeka okuphezulu kwemishini futhi ivimbele ukulimala kombani. Igumbi lekhompiyutha lesikhungo senethiwekhi liyindawo enenani eliphezulu kakhulu lemishini. Uma isiteleka sombani senzeke, sizobangela ukulahlekelwa kwezomnotho okungenakubalwa kanye nemithelela yezenhlalo. Ngokwezinhlinzeko ezifanele ze-IEC61024-1-1 ejwayelekile, izinga lokuvikela umbani legumbi lekhompiyutha elimaphakathi kufanele lisethwe njengedizayini evamile Yekilasi. Njengamanje, igumbi lokusabalalisa amandla eliyinhloko lesakhiwo linikeza ukuvikelwa kombani wezinga lokuqala ngokusho kwesakhiwo sokuvikela umbani. idivayisi). Umvikeli ohlinzayo usebenzisa imojuli ezimele futhi kufanele abe nenkomba yokuhluleka kwe-alamu. Lapho imojuli ishaywa umbani futhi yehluleka, imojula ingashintshwa iyodwa ngaphandle kokuthatha indawo yomvikeli wokuhlinzwa. Imingcele eyinhloko nezinkomba zesibambisi sombani esiyinhlanganisela nesesekondari: ukugeleza kwesigaba esisodwa: ≥40KA (8/20μs), isikhathi sokuphendula: ≤25ns 2. Ukwakhiwa kwesistimu yokubeka phansi Igumbi lenethiwekhi yekhompiyutha kufanele libe nalezi zizathu ezine ezilandelayo: indawo ye-DC yesistimu yekhompyutha, indawo yokusebenza ye-AC, indawo yokuvikela i-AC kanye nendawo yokuvikela umbani. Ukumelana nesistimu ye-grounding ngayinye imi kanje: 1. Ukumelana nokuqina kwe-DC kwemishini yesistimu yekhompyutha akukho ngaphezu kwe-1Ω. 2. Ukumelana okuphansi kwendawo yokuvikela ye-AC akumele kube kukhulu kuno-4Ω; 3. Ukumelana okuphansi kwendawo yokuvikela umbani akufanele kube kukhulu kuno-10Ω; 4. Ukumelana okuphansi kwendawo yokusebenza ye-AC akumele kube kukhulu kuno-4Ω; Uhlelo lokuvikela umbani kanye nesisekelo segumbi lemishini yenethiwekhi luhlanganisa: 1. Ukuxhumeka kwe-equipotential ekamelweni lemishini Kumiswe ibha yaphansi emise okwendandatho egumbini lempahla yenethiwekhi. Imishini kanye ne-chassis ekamelweni lezinto zokusebenza kuxhunywe kubha yebhasi ephansi ngendlela yokuxhumeka kwe-equipotential yohlobo lwe-S, futhi abekwe ngaphansi kokusekelwa kwesitezi esiphakanyisiwe nge-50 * 0.5 ye-copper-platinum strips. 1200*1200 igridi, ukubeka amateyipu ethusi angama-30*3 (40*4) azungeze igumbi lemishini. Amateyipu ethusi afakwe amatheminali aphansi akhethekile. Zonke izinto zensimbi egumbini lemishini zisekelwe ngezintambo zethusi ezilukiwe ezithambile futhi zixhunywe esakhiweni. indawo evikelekile. Zonke izintambo ezisekelwe phansi (okuhlanganisa okokusebenza, izivikeli zokuhlinza, izintambo zocingo, njll.) kanye nezintambo zezintambo zensimbi kuphrojekthi kufanele zibe zifushane, zibe zicaba futhi ziqonde, futhi ukumelana nomhlabathi kufanele kube ngaphansi noma kulingane no-1 ohm. 2. Umklamo wokuvikela igumbi lekhompyutha Isivikelo salo lonke igumbi lezinto zokusebenza siyisivikelo esine-hexahedral esinamapuleti ensimbi anombala. Ipuleti lokuvikela lishiselwe ngaphandle komthungo ngaphambili, futhi umzimba ovikelayo wodonga usekelwe endaweni engekho ngaphansi kwezingu-2 ngebha ephansi ohlangothini ngalunye. 3. Idizayini yesisetshenziswa esiphansi ekamelweni lekhompyutha Ngenxa yezidingo eziphakeme zokumelana nokubekwa phansi kwegumbi lenethiwekhi, kwenezelwa idivayisi yokwenziwa yaphansi eduze nesakhiwo, futhi izinsimbi ezingu-15 zama-engeli angama-galvanized zashayelwa endaweni yegridi yomhlabathi, zishiselwe ngensimbi eyisicaba, futhi zagcwaliswa ngemuva nge-ejenti yokunciphisa ukumelana. Isisekelo esimile segumbi lezinto zokusebenza kwethulwa ngocingo oluwumgogodla lwe-50mm² olunemicu eminingi yethusi.
