Izinhlobo eziningana zokubeka phansi zegumbi lekhompyutha Kunezinhlobo ezine eziyisisekelo ekamelweni lekhompiyutha, okuyilawa: indawo enengqondo ye-DC eqondene nekhompyutha, indawo yokusebenza ye-AC, indawo yokuvikela ukuphepha, nendawo yokuvikela umbani. 1. Isistimu yegumbi lekhompyutha Faka igridi yethusi ngaphansi kwesitezi esiphakanyisiwe segumbi lekhompyutha, bese uxhuma amagobolondo anganawo amandla azo zonke izinhlelo zekhompiyutha egumbini lekhompyutha kugridi yethusi bese uholela phansi. Uhlelo lwe-grounding lwegumbi lekhompiyutha luthatha uhlelo olukhethekile lokumisa phansi, futhi uhlelo olukhethekile lokumisa phansi luhlinzekwa yisakhiwo, futhi ukumelana nokunciphisa kungaphansi noma kulingana no-1Ω. 2. Izinqubo eziqondile zokubeka i-equipotential egumbini lekhompyutha: Sebenzisa amateyipu ethusi angu-3mm × 30mm ukuwela futhi wenze isikwele ngaphansi kwesitezi esiphakanyisiwe segumbi lempahla. Izimpambanomgwaqo zinyakaziswa ngezikhundla ezisekelwe phansi. Izimpambano zihlanganiswe ndawonye futhi zihlanganiswe nama-pad insulators ngaphansi kwamateyipu ethusi. Ibanga elingu-400mm ukusuka odongeni egumbini lekhompyutha ukusebenzisa imicu yethusi engu-3mm×30mm eduze kodonga ukuze kwakhiwe igridi yomhlabathi yohlobo lwe-M noma u-S. Uxhumano phakathi kwemichilo yethusi luboshwe ngesikulufu esingu-10mm bese lushiselwa ngethusi, bese luholela phansi ngentambo yethusi engu-35mm2. Ulayini uxhunywe kumzimba ohlangene wesisekelo wesakhiwo, ngaleyo ndlela wenza uhlelo lwe-Faraday cage grounding, futhi uqinisekisa ukuthi ukumelana nesisekelo akukhulu kune-1Ω. Uxhumano lwe-equipotential lwegumbi lezinto zokusebenza: Yenza uxhumano lwe-equipotential lwekeel yophahla, i-wall keel, ubakaki waphansi ophakanyisiwe, amapayipi wesistimu okungeyona eyekhompyutha, izicabha zensimbi, amafasitela, njll., futhi uxhume amaphuzu amaningi ekamelweni lezinto zokusebenza ngocingo oluphansi oluyi-16m m2. Igridi yethusi. 3. Shintshanisa indawo yokusebenza Isisekelo esidingekayo ekusebenzeni kusistimu yamandla (iphoyinti elingathathi hlangothi lekhabhinethi yokusabalalisa amandla lisekelwe) akufanele libe ngaphezu kuka-4 ohms. Ulayini ongathathi hlangothi oxhunywe endaweni engathathi hlangothi ye-transformer noma i-generator esekelwe ngokuqondile ibizwa ngokuthi umugqa ongathathi hlangothi; ukuxhunywa kukagesi kwephoyinti elilodwa noma ngaphezulu kumugqa ongathathi hlangothi phansi futhi kubizwa ngokuthi i-grounding ephindaphindiwe. Indawo yokusebenza ye-AC iphoyinti elingathathi hlangothi elisekelwe ngokuthembekile. Lapho iphuzu lokungathathi hlangothi lingagxiliwe, uma isigaba esisodwa sithinta phansi futhi umuntu ethinta esinye isigaba, amandla okuxhumana emzimbeni womuntu azodlula i-voltage yesigaba, futhi lapho iphuzu lokungathathi hlangothi ligxiliwe, kanye nokumelana okuyisisekelo kokungathathi hlangothi. iphuzu lincane kakhulu, khona-ke I-voltage esetshenziswa emzimbeni womuntu ilingana ne-voltage yesigaba; ngesikhathi esifanayo, uma iphuzu lokungathathi hlangothi lingasekelwe phansi, isisekelo samanje sincane kakhulu ngenxa ye-impedance enkulu phakathi kwephuzu elingathathi hlangothi kanye nomhlabathi; imishini yokuvikela ehambisanayo ayikwazi ukunqamula ukunikezwa kwamandla ngokushesha, okubangela ukulimala kubantu kanye nemishini. dala umonakalo; kungenjalo. 4. Indawo ephephile Indawo yokuvikela ukuphepha isho ukugxila okuhle phakathi kwamabhokisi ayo yonke imishini nezinto zokusebenza egumbini lekhompiyutha kanye nomzimba (i-casing) wezinto ezisizayo ezifana nezinjini nama-air conditioner kanye nomhlabathi, okungafanele kube ngaphezu kuka-4 ohms. Lapho ama-insulators emishini kagesi ehlukahlukene egunjini lemishini yonakele, kuzoba usongo ekuphepheni kwemishini kanye nabaqhubi kanye nabasebenzi abalungisayo. Ngakho-ke, i-casing yezinto zokusebenza kufanele isekelwe ngokuthembekile. 5. Indawo yokuvikela umbani Okusho ukuthi, ukumiswa kwesistimu yokuvikela umbani ekamelweni lekhompiyutha ngokuvamile kungcwatshwa ngaphansi komhlaba ngemigqa yokuxhuma evundlile kanye nezinqwaba zokumisa eziqondile, ikakhulukazi ukuhola umbani osuka kudivayisi ethola umbani ukuya kudivayisi yokubeka phansi, okungafanele ibe ngaphezu kwe-10. ohms. Idivayisi yokuvikela umbani ingahlukaniswa izingxenye ezintathu eziyisisekelo: idivayisi yokunqamula umoya, i-down-conductor kanye nedivayisi yokubeka phansi. Ithuluzi lokunqamula umoya liyi-conductor yensimbi eyamukela umbani wamanje. Kulesi sixazululo, i-down-conductor kuphela yesibambi sombani ixhunywe kubha yethusi ephansi ekhabhinethi yokusabalalisa amandla. Ukumelana okuphansi kuyadingeka ukuthi kube ngaphansi noma kulingane no-4Ω.
