Dhizaini yeMheni Dziviriro Grounding System muNetwork Computer Room 1. Dhizaini yekudzivirira mheni Iyo mheni yekudzivirira pasi system yakakosha subsystem yekudzivirira isina kusimba ikozvino chaiyo midziyo uye makamuri emidziyo, iyo inonyanya kuve nechokwadi chepamusoro kuvimbika kwemidziyo uye kudzivirira kukuvadza kwemheni. Iyo network yepakati komputa kamuri inzvimbo ine yakakwirira kwazvo yemidziyo kukosha. Kana kurova kwemheni kuchingoitika, zvinokonzeresa kurasikirwa kwehupfumi kusingaverengeki uye kukanganisa munharaunda. Zvinoenderana nezvinodiwa zveIEC61024-1-1 yakajairwa, iyo mheni yekudzivirira yekamuri yepakati komputa inofanirwa kusetwa seMakirasi maviri akajairwa dhizaini. Parizvino, imba huru yekugovera simba rechivako ichi inopa yekutanga-yemwero yekudzivirira mheni zvinoenderana nekuvaka mheni yekudzivirira dhizaini yakatarwa. mudziyo). Iyo yekuvhiya inodzivirira inotora yakazvimirira module uye inofanirwa kunge iine yekutadza alarm chiratidzo. Kana module ikarohwa nemheni uye ikatadza, module inogona kutsiviwa yega pasina kutsiva iyo yese inodzivirira yekuvhiya. Iwo makuru ma paramita uye zviratidzo zveyechipiri uye yepamusoro inoumba mheni inosunga: imwe-chikamu kuyerera: ≥40KA (8/20μs), nguva yekupindura: ≤25ns 2. Grounding system design Imba yekombuta network inofanirwa kunge iine zvikonzero zvina zvinotevera: iyo DC pasi yekombuta system, iyo AC yekushanda pasi, iyo AC yekudzivirira pasi uye nzvimbo yekudzivirira mheni. Kupokana kwega yega grounding system kunotevera: 1. Iyo DC yekumisa kuramba kwekombiyuta system michina haisi kupfuura 1Ω. 2. Kurwisana kwepasi kweiyo AC yekudzivirira pasi haifaniri kunge yakakura kudarika 4Ω; 3. Kurwisana kwepasi kwepasi rekudzivirira mheni hakufaniri kuva kukuru kupfuura 10Ω; 4. Kupikisa kwepasi kwe AC nzvimbo yekushanda haifaniri kuva yakakura kudarika 4Ω; Iyo yekudzivirira mheni uye yekumisa system ye network network midziyo inosanganisirawo: 1. Equipotential yekubatanidza muimba yemidziyo A ring-shaped grounding busbar inogadzikwa muimba yemidziyo yetiweki. Midziyo uye chassis mukamuri yemidziyo yakabatana kune yekumisa bhasi muchimiro cheS-mhando equipotential yekubatanidza, uye inoradzikwa pasi pekutsigirwa kwakasimudzwa pasi ne50 * 0.5 copper-platinum mitsetse. 1200 * 1200 grid, kuisa 30 * 3 (40 * 4) matepi emhangura kumativi eimba yemidziyo. Iwo matepi emhangura akashongedzerwa neakakosha grounding terminals. Zvese simbi zvemukati mukamuri yemidziyo zvakadzikwa netambo dzakarukwa dzakapfava dzemhangura uye dzakabatana nechivakwa. nzvimbo yakachengetedzwa. Waya dzese dzepasi (kusanganisira midziyo, vadziviriri vekuwedzera, tambo dzewaya, nezvimwewo) uye simbi dzesimbi mupurojekiti dzinofanirwa kunge dzakapfupika, dzakadzikama uye dzakatwasuka, uye kushomeka kwepasi kunofanira kunge kuri kushoma kana kuenzana ne1 ohm. 2. Computer room shielding design Kudzivirira kwekamuri yese yemidziyo ndeye hexahedral shielding ine mavara esimbi mahwendefa. Iyo shielding plate yakasungwa zvisina musono pamberi, uye iyo inodzivirira yemadziro yakadzikwa pane isingasviki 2 nzvimbo ine grounding busbar padivi rega rega. 3. Dhizaini yekugadzika mudziyo mukamuri yekombuta Nekuda kweiyo yakakwira yekumisa pasi zvinodiwa yekamuri yetiweki, chigadziriso chekugadzika chakawedzerwa padyo nechivako, uye simbi gumi neshanu dzemakona dzakaiswa mukati megidhi yevhu, yakakwenenzverwa nesimbi yakati sandara, uye yakazadzwa neanodzikisira kudzivirira. Iyo yakagadzika pasi yekamuri yemidziyo inounzwa kuburikidza ne50mm² akawanda-strand copper core waya.
