Kwiinkqubo zokudibanisa inethiwekhi, izixhobo ezikhethekileyo zokukhusela umbane wesignali zingafakwa ngaphambi kokuba imigca yesignali yenethiwekhi ingene kwi-router ye-WAN; Izixhobo zokukhusela umbane wesignali kunye ne-RJ45 interfaces zifakwe kwi-system backbone switch, iseva engundoqo, kunye nokungena komgca wesignali yesebe ngalinye kunye neseva ngokulandelanayo (njenge-RJ45-E100). Ukukhethwa kombambeli womqondiso kufuneka kuqwalaselwe ngokubanzi umbane osebenzayo, izinga logqithiso, ifom ye-interface, njl njl.① Faka izibuko enye i-RJ45 yesibambi somqondiso wezibuko kwindawo yongeniso yomncedisi ukukhusela iseva.② I-24-port network switches idityaniswe ngokulandelelana kunye ne-24-port RJ45 i-port signal arresters ukuphepha umonakalo kwisixhobo ngenxa yokungeniswa kombane okanye ukuphazamiseka kwe-electromagnetic ekungeneni kunye nesibini esijijekileyo.③ Fakela izibuko le-RJ11 yesibambi somqondiso wezibuko kwi-DDN ezinikeleyo yomgca wokufumana isixhobo ukukhusela izixhobo kumgca onikezelweyo weDDN.④ Faka i-coaxial port i-antenna feeder lightning arrester ngaphambili ekupheleni kwesathelayithi efumana izixhobo zokukhusela izixhobo ezifumanayo.(3) Ukukhuselwa kombane kwigumbi lenkqubo yokubeka iliso① Fakela isixhobo sokukhusela umbane womqondiso wevidiyo kwisiphelo sokuphuma kwentambo yevidiyo yerekhoda yevidiyo yediski enzima okanye usebenzise ibhokisi yokhuselo lombane lombane wevidiyo, izibuko ezili-12 zikhuselwe ngokupheleleyo kwaye kulula ukuzifaka.② Faka isixhobo sokukhusela umbane wokulawula umbane (DB-RS485/422) kumgca wokulawula wokungena ekupheleni kwe-matrix kunye ne-splitter yevidiyo.③ Umgca wefowuni wegumbi lekhompyutha wamkela isixhobo sokukhusela umbane wesandi, esiqhagamshelwe kuthotho kunye nomgca wefowuni kumphambili wefowuni, olungele ukufakela nokugcinwa.④ Faka isixhobo sokukhusela umbane wolawulo kwindawo yofikelelo yomgca wesignali ngaphambili kwisiphelo sesixhobo se-alam ukunika ukhuseleko lombane olusebenzayo kumgca wesignali wesixhobo se-alam.Qaphela: Zonke izixhobo zokukhusela umbane kufuneka zibekwe kakuhle. Xa ukhetha izixhobo zokukhusela umbane, ingqalelo kufuneka ihlawulwe kwifom ye-interface kunye nokuthembeka kwesiseko. Iingcingo ezikhethekileyo zokumisa kufuneka zibekwe kwiindawo ezibalulekileyo. Ukugcina kude kangangoko, hlukana emhlabeni.4. Uqhagamshelwano lwe-equipotential kwigumbi lekhompyuthaNgaphantsi komgangatho we-anti-static wegumbi lezixhobo, cwangcisa i-40 * 3 imivalo yobhedu ecaleni komhlaba ukwenza i-covale-loop grounding busbar. Dlulisa iqokobhe lentsimbi lebhokisi yokuhambisa, umhlaba wamandla, umhlaba wokubamba, iqokobhe lekhabhathi, intsimbi ekhuselweyo yocingo, iingcango kunye neefestile, njl. njl izixhobo zenkqubo, kunye nesakhelo sokuzihlukanisa phantsi komgangatho we-anti-static. I-point equipotential grounding iya kwi-busbar. Kwaye sebenzisa i-equipotential bonding wire 4-10mm2 copper copper core bolt ikliphu yocingo ebotshelelwe njengesixhobo soqhagamshelwano. Ngexesha elifanayo, fumana intsimbi ephambili yentsimbi yesakhiwo kwigumbi lekhompyutheni, kwaye iqinisekisiwe ukuba idibene kakuhle kunye nombambeli wombane emva kokuvavanya. Sebenzisa i-14mm yentsimbi engqukuva yegalvanized ukudibanisa i-busbar yokumisa kunye nayo ngokusebenzisa i-joint conversion ye-copper-iron. I-equipotential yenziwa. Injongo yokusebenzisa igridi edibeneyo yokubambisana kukuphelisa ukungafani okunokwenzeka phakathi kweegridi zendawo kunye nokuqinisekisa ukuba izixhobo azibonakalisi ngokuphikisana nombane.5. Ukuveliswa kwegridi kunye noyiloI-Grounding yenye yezona zinto zibalulekileyo zeteknoloji yokukhusela umbane. Nokuba sisibetho esithe ngqo sombane okanye umbane ongeniswayo, umbane ophumayo ekugqibeleni ungeniswa emhlabeni. Ke ngoko, kwiidatha ezibuthathaka (umqondiso) izixhobo zonxibelelwano, akunakwenzeka ukuphepha ngokuthembekileyo umbane ngaphandle kwenkqubo efanelekileyo kunye neyokumisa kakuhle. Ngoko ke, kwinethiwekhi yokwakhiwa kwesakhiwo kunye nokuchasana komhlaba> 1Ω, kuyimfuneko ukulungisa ngokweemfuno ezicacileyo zokuphucula ukuthembeka kwenkqubo yokumisa igumbi lezixhobo. Ngokwemeko ethile, indawo esebenzayo yegridi yokumisa kunye nesakhiwo segridi yokumisa iphuculwe ngokuseka iindlela ezahlukeneyo zeegridi zokumisa (kubandakanywa nemizimba esezantsi ethe tye kunye nezidumbu ezisezantsi) ecaleni kwesakhiwo segumbi lekhompyuter.Xa usebenzisa isixhobo esiqhelekileyo sokumisa, ixabiso eliqhelekileyo lokumelana nomhlaba akufanele libe likhulu kune-1Ω;Xa isixhobo esikhethekileyo sokumisa sisetyenzisiweyo, ixabiso layo lokumelana nomhlaba akufanele libe likhulu kune-4Ω.Iimfuno ezisisiseko zezi zilandelayo:I-1) Yenza igridi ejikelezayo ejikeleze isakhiwo ukugqiba isixhobo esisebenzayo sokumisa izixhobo kunye neendleko eziphantsi zokufakela;2) Iimfuno zexabiso lokumelana nokunciphisa R ≤ 1Ω;3) Umzimba womhlaba kufuneka ubekwe malunga ne-3 ~ 5m kude nesakhiwo esikhulu apho igumbi lekhompyutha likhona;4) Umzimba osezantsi othe tyaba kunye nothe nkqo kufuneka ungcwatywe malunga ne-0.8m ngaphantsi komhlaba, umzimba wokumisa othe nkqo kufuneka ube yi-2.5m ubude, kunye nomzimba wokumisa othe nkqo kufuneka usetwe rhoqo nge-3 ~ 5m. Umzimba osezantsi yi-50 × 5mm eshushu-dip yentsimbi ethe tyaba;5) Xa i-mesh yomhlaba idityanisiwe, indawo ye-welding kufuneka ibe ≥6 amaxesha kwindawo yokudibanisa, kunye ne-welding point kufuneka iphathwe nge-anti-corrosion and anti-rust treatment;6) Iminatha kwiindawo ezahlukahlukeneyo kufuneka idityaniswe kunye nemivalo yensimbi yeentsika ezininzi zokwakha kwi-0.6 ~ 0.8m ngaphantsi komhlaba, kwaye iphathwe nge-anti-corrosion kunye ne-anti-rust treatment;7) Xa i-conductivity yomhlaba ihlwempuzekile, indlela yokubeka i-arhente yokunciphisa i-resistance iya kwamkelwa ukwenza ukuchasana komhlaba ≤1Ω;8) I-backfill kufuneka ibe ludongwe olutsha kunye nokuhanjiswa kombane okungcono;I-9) I-Multi-point welding kunye nesiseko somnatha womhlaba wesakhiwo, kunye nokugcina amanqaku okuvavanya umhlaba.Oku kungasentla yindlela yemveli enexabiso eliphantsi nesebenzayo. Ngokwemeko yangempela, i-grid ye-grounding material ingaphinda isebenzise izixhobo ezintsha zobugcisa, ezifana ne-electrolytic-free ion system grounding system, imodyuli ye-low-resistance grounding module, i-copper-clad yentsimbi yexesha elide kunye nokunye.
