Iindlela ezininzi zokumisa igumbi lekhompyuter Kukho iifom ezine zokumisa kwigumbi lekhompyuter, ezizezi: umhlaba ocacileyo we-DC wekhompyuter, indawo yokusebenza ye-AC, umhlaba wokhuseleko, kunye nomhlaba wokhuseleko lombane. 1. Inkqubo yokumisa igumbi lekhompyutha Faka igridi yobhedu phantsi komgangatho ophakanyisiweyo wegumbi lekhompyutha, kwaye udibanise iigobolondo ezingenamandla kuzo zonke iinkqubo zekhompyutheni kwigumbi lekhompyutheni kwigridi yobhedu kwaye emva koko uholele emhlabeni. Inkqubo yokumisa yegumbi lekhompyutheni ithatha inkqubo ekhethekileyo yokumisa, kwaye inkqubo ekhethekileyo yokumisa inikezelwa sakhiwo, kwaye ukuchasana komgangatho kungaphantsi okanye ukulingana ne-1Ω. 2. Iinkqubo ezithe ngqo ze-equipotential grounding kwigumbi lekhompyutha: Sebenzisa i-3mm × 30mm iiteyiphu zobhedu ukuwela kwaye wenze isikwere phantsi komgangatho ophakamileyo wegumbi lezixhobo. Ii-intersections ziphazamisekile kunye nezikhundla ezixhaswa ngumgangatho ophakanyisiweyo. Ii-intersections zidibene kunye kwaye zilungiswe kunye ne-pad insulators phantsi kweetape zobhedu. Umgama oyi-400mm ukusuka eludongeni kwigumbi lekhompyutha kukusebenzisa imicu yobhedu eyi-3mm×30mm ecaleni kodonga ukwenza uhlobo lwe-M okanye igridi yomhlaba yohlobo lwe-S. Udibaniso phakathi kwemicu yobhedu lucikizekile ngesikrufu se-10mm emva koko ludityaniswe ngobhedu, luze lukhokele phantsi ngentambo yobhedu eyi-35mm2. Umgca uqhagamshelwe kumzimba odibeneyo wesakhiwo, ngaloo ndlela wenza inkqubo ye-Faraday cage grounding system, kunye nokuqinisekisa ukuba ukuchasana komhlaba akukho mkhulu kune-1Ω. Uqhagamshelo lwe-equipotential lwegumbi lezixhobo: Yenza uqhagamshelo lwe-equipotential kwi-ceiling keel, i-wall keel, isibiyeli somgangatho ophakanyisiweyo, imibhobho yenkqubo engeyiyo yekhompyutheni, iingcango zentsimbi, iifestile, njl. Igridi yobhedu. 3. Utshintshiselwano ngendawo yokusebenza Isiseko esifunekayo ekusebenzeni kwinkqubo yamandla (indawo engathathi hlangothi yekhabhinethi yokusabalalisa amandla isekelwe) akufanele ibe ngaphezu kwe-4 ohms. Umgca ongathathi hlangothi oxhunywe kwindawo engathathi hlangothi ye-transformer okanye i-generator esekelwe ngokuthe ngqo ibizwa ngokuba ngumgca ongathathi hlangothi; uxhulumaniso lombane lwenye okanye amanqaku amaninzi kumgca ongathathi hlangothi emhlabeni kwakhona kuthiwa yi-grounding ephindaphindiweyo. Indawo yokusebenza ye-AC yindawo engathathi hlangothi esekelwe ngokuthembekileyo. Xa indawo engathathi hlangothi ingasekelwanga, ukuba isigaba esinye sichukumisa umhlaba kwaye umntu uchukumisa esinye isigaba, i-voltage yoqhagamshelwano emzimbeni womntu iya kudlula i-voltage yesigaba, kwaye xa indawo engathathi hlangothi isekelwe, kunye nokuchasana kokungathathi hlangothi. inqaku lincinci kakhulu, emva koko I-voltage esetyenziswe kumzimba womntu ilingana ne-voltage yesigaba; ngelo xesha, ukuba indawo engathathi hlangothi ayisekelwanga, i-grounding current incinci kakhulu ngenxa ye-impedance enkulu elahlekileyo phakathi kwendawo engathathi hlangothi kunye nomhlaba; izixhobo zokukhusela ezihambelanayo azikwazi ukunqumla ukunikezelwa kwamandla ngokukhawuleza, kubangela umonakalo kubantu kunye nezixhobo. bangela ingozi; kungenjalo. 4. Indawo ekhuselekileyo Umhlaba wokukhusela ukhuseleko ubhekisela kwisiseko esihle phakathi kwee-casings zabo bonke oomatshini kunye nezixhobo kwigumbi lekhompyutheni kunye nomzimba (i-casing) wezixhobo ezincedisayo ezifana neenjini kunye ne-air conditioners kunye nomhlaba, ongafanele ube mkhulu kune-4 ohms. Xa i-insulators yezixhobo ezahlukeneyo zombane kwigumbi lezixhobo zonakaliswe, iya kuba yingozi kukhuseleko lwezixhobo kunye nabaqhubi kunye nabasebenzi bokulondoloza. Ngoko ke, i-casing yesixhobo kufuneka isekelwe ngokuthembekileyo. 5. Umhlaba wokukhusela umbane Oko kukuthi, ukusekwa kwenkqubo yokukhusela umbane kwigumbi lekhompyutheni ngokuqhelekileyo kungcwatywa phantsi komhlaba kunye nemigca yokudibanisa ethe tye kunye neemfumba zokumisa ngokuthe nkqo, ngokukodwa ukukhokela umbane wangoku ukusuka kwisixhobo sokufumana umbane kwisixhobo sokumisa, esingafanelanga ukuba sibe sikhulu kune-10. ohms. Isixhobo sokukhusela umbane sinokuhlulwa sibe ngamacandelo amathathu asisiseko: isixhobo sokuphelisa umoya, i-conductor ephantsi kunye nesixhobo sokumisa. Isixhobo sokuphelisa umoya ngumqhubi wesinyithi ofumana umbane wangoku. Kwesi sisombululo, kuphela i-conductor ephantsi yombambisi wombane idityaniswe kwi-bar yobhedu yokumisa kwikhabhinethi yokusabalalisa amandla. Ukuxhathisa umhlaba kufuneka ube ngaphantsi okanye ulingane no-4Ω.
