Mitundu ingapo yoyambira ya chipinda cha makompyuta Pali mitundu inayi yoyambira m'chipinda cha makompyuta, yomwe ndi: malo opangira makompyuta a DC, malo ogwirira ntchito a AC, malo otetezera chitetezo, ndi malo otetezera mphezi. 1. Pakompyuta chipinda pansi dongosolo Ikani gridi yamkuwa pansi pa malo okwera a chipinda cha makompyuta, ndikugwirizanitsa zipolopolo zopanda mphamvu za machitidwe onse apakompyuta mu chipinda cha makompyuta ku gridi yamkuwa ndiyeno kutsogolera pansi. Dongosolo lokhazikika la chipinda cha makompyuta limagwiritsa ntchito njira yapadera yokhazikitsira pansi, ndipo dongosolo lapadera lokhazikika limaperekedwa ndi nyumbayo, ndipo kukana kwapansi kumakhala kochepa kapena kofanana ndi 1Ω. 2. Mchitidwe wachindunji wa kukhazikitsa ma equipotential mu chipinda cha makompyuta: Gwiritsani ntchito matepi amkuwa a 3mm × 30mm kuti muwoloke ndikupanga sikweya pansi pachipinda chokwera cha chipinda cha zida. Njira zodutsamo zimagwedezeka ndi malo omwe amathandizidwa ndi pansi. Njira zodutsamo zimalumikizidwa palimodzi ndikukhazikika ndi zoteteza pad pansi pa matepi amkuwa. Mtunda wa 400mm kuchokera pakhoma mu chipinda cha makompyuta ndi kugwiritsa ntchito 3mm × 30mm zingwe zamkuwa pakhoma kupanga gulu la M-mtundu kapena S-mtundu wa pansi. Kulumikizana pakati pa zingwe zamkuwa kumapukutidwa ndi wononga 10mm ndiyeno kumangiriridwa ndi mkuwa, kenako kutsika kudzera pa chingwe chamkuwa cha 35mm2. Mzerewu umagwirizanitsidwa ndi gulu logwirizanitsa la nyumbayo, motero kupanga dongosolo la pansi pa khola la Faraday, ndikuonetsetsa kuti kukana kwapansi sikuli kwakukulu kuposa 1Ω. Kulumikizira kwa Equipotential kwa chipinda cha zida: Pangani kulumikizana kwa equipotential kwa siling'i, keel ya khoma, bulaketi yokwezeka pansi, mapaipi osagwiritsa ntchito makompyuta, zitseko zachitsulo, mazenera, ndi zina zambiri, ndikulumikiza mfundo zingapo kuchipinda chazida chokhazikika kudzera pa waya wa 16m m2. Gridi yamkuwa. 3. Kusinthana malo antchito Kuyika komwe kumafunikira kuti mugwiritse ntchito mphamvu yamagetsi (malo osalowerera ndale ya kabati yogawa mphamvu yakhazikitsidwa) sikuyenera kukhala wamkulu kuposa 4 ohms. Mzere wosalowerera ndale wolumikizidwa ku gawo losalowerera ndale la thiransifoma kapena jenereta yokhazikika mwachindunji imatchedwa mzere wosalowerera; kugwirizana kwa magetsi kwa mfundo imodzi kapena zingapo pa mzere wosalowerera mpaka pansi kumatchedwanso kubwereza mobwerezabwereza. Malo ogwirira ntchito a AC ndiye malo osalowerera omwe ali okhazikika. Ngati gawo losalowerera ndale silinakhazikike, ngati gawo limodzi likhudza pansi ndipo munthu akhudza gawo lina, mphamvu yolumikizana ndi thupi la munthu ipitilira mphamvu yamagetsi, ndipo gawo lopanda ndale likakhala pansi, komanso kukana kopanda ndale. mfundo ndi yaing'ono kwambiri, ndiye The voteji ntchito kwa thupi la munthu ndi ofanana ndi gawo voteji; panthawi imodzimodziyo, ngati mfundo yosalowerera ndale siinakhazikitsidwe, malo oyambira ndi ochepa kwambiri chifukwa cha kusokonezeka kwakukulu pakati pa malo osalowerera ndale ndi pansi; zida zotetezera zogwirizana sizingathe kudula magetsi mwamsanga, kuwononga anthu ndi zipangizo. kuwononga; mwinamwake. 4. Malo otetezeka Malo otetezera chitetezo amatanthauza kukhazikika bwino pakati pa makina a makina onse ndi zipangizo mu chipinda cha makompyuta ndi thupi (casing) la zipangizo zothandizira monga ma motors ndi ma air conditioners ndi pansi, zomwe siziyenera kukhala zazikulu kuposa 4 ohms. Pamene ma insulators a zipangizo zosiyanasiyana zamagetsi mu chipinda cha zipangizo awonongeka, zidzasokoneza chitetezo cha zipangizo ndi ogwira ntchito ndi ogwira ntchito yosamalira. Chifukwa chake, chosungira cha zidacho chiyenera kukhala chokhazikika. 5. Malo oteteza mphezi Ndiye kuti, kukhazikitsidwa kwa chitetezo cha mphezi mu chipinda cha makompyuta nthawi zambiri kumakwiriridwa mobisa ndi mizere yolumikizira yopingasa ndi milu yokhazikika, makamaka kutsogolera mphezi kuchokera ku chipangizo cholandirira mphezi kupita ku chipangizo choyatsira, chomwe sichiyenera kukhala chachikulu kuposa 10. ohm. Chipangizo chotetezera mphezi chikhoza kugawidwa m'magawo atatu: chipangizo chochotsera mpweya, choyendetsa pansi ndi chipangizo choyatsira pansi. Chipangizo chochotsa mpweya ndi chowongolera chitsulo chomwe chimalandira mphezi. Mu yankho ili, kokha-conductor wapansi wa chomangirira mphezi amalumikizidwa ndi chitsulo chamkuwa chokhazikika mu kabati yogawa mphamvu. Kukana kwapansi kumafunika kukhala kochepa kapena kofanana ndi 4Ω.
