Mhando dzinoverengeka dzekugadzika kwekamuri yekombuta Pane mafomu mana ekudzika mukamuri yekombuta, anoti: komputa-chaiyo DC logic pasi, AC yekushanda, nzvimbo yekudzivirira, uye nzvimbo yekudzivirira mheni. 1. Computer room grounding system Isa girasi remhangura pasi pevhu rakasimudzwa rekamuri yekombuta, uye batanidza mabhomba asina simba emakomputa ese ari mukamuri yekombuta kune mhangura grid uye wozotungamira pasi. Iyo yekugadzika system yekamuri yekombuta inotora yakakosha pasi system, uye yakakosha pasi system inopiwa nechivako, uye kushomeka kwepasi kudiki kana kuenzana ne1Ω. 2. Maitirwo chaiwo e equipotential grounding muimba yekombuta: Shandisa 3mm × 30mm matepi emhangura kuyambuka uye kugadzira sikweya pasi peuriri hwakasimudzwa hwekamuri yemidziyo. Mharadzano inodzika nezvigaro zvakatsigirwa neuriri hwakasimudzwa. Mharadzano dzakabatanidzwa pamwe chete uye dzakagadziriswa nemapadhi insulators pasi pematepi emhangura. Chinhambwe che400mm kubva kumadziro mukamuri yekombuta kushandisa 3mm×30mm mitsetse yemhangura pamadziro kugadzira M-mhando kana S-mhando yepasi grid. Kubatana pakati pemachira emhangura kunochekwa ne 10mm sikuruu yozoiswa welded nemhangura, yozotungamira ichidzika netambo yemhangura ye35mm2. Mutsara wakabatanidzwa kune mubatanidzwa wepasi pevhu rechivako, nokudaro uchigadzira Faraday cage grounding system, uye kuve nechokwadi kuti kupikisa kwepasi hakusi kukuru kupfuura 1Ω. Equipotential yekubatanidza yekamuri yemidziyo: Ita equipotential yekubatanidza sirin'i keel, madziro keel, yakasimudzwa pasi bracket, mapaipi eisina-komputa system, magonhi esimbi, mahwindo, nezvimwe, uye batanidza akawanda mapoinzi kukamuri yemidziyo inodzika kuburikidza ne16m m2 pasi waya. Mhangura grid. 3. Kuchinjana nzvimbo yebasa Iyo ivhu inodiwa kuti ishande musimba remagetsi (nzvimbo isina kwayakarerekera yemagetsi ekugovera kabati yakamiswa) haifanirwe kunge yakakura kupfuura 4 ohms. Mutsara usina kwawakarerekera wakabatana neutera poindi ye transformer kana jenareta yakananga pasi inonzi inonzi neutral line; kubatanidzwa kwemagetsi kweimwe kana imwe pfungwa pamutsara usina kwawakarerekera pasi zvakare kunonzi kudzokororwa pasi. Iyo AC yekushanda pasi ndiyo nzvimbo isina kwayakarerekera iyo yakavimbika yakavakirwa. Kana iyo nzvimbo isina kwayakarerekera isina kudzika, kana imwe nhanho ikabata pasi uye munhu akabata imwe nhanho, iyo yekubata voltage pamuviri wemunhu inodarika iyo phase voltage, uye kana nzvimbo yavakarerekera ichidzika, uye kuramba kwepasi kwevasina kwavakarerekera. poindi idiki kwazvo, ipapo Iyo voltage inoshandiswa kumuviri wemunhu yakaenzana nechikamu chemagetsi; panguva imwecheteyo, kana nzvimbo isina kwayakarerekera isina kudzika pasi, iyo yepasi ikozvino idiki kwazvo nekuda kweiyo yakakura kurasika impedance pakati pekusarerekera nzvimbo uye pasi; midziyo yekudzivirira inoenderana haigone kugura simba remagetsi nekukurumidza, zvichikonzera kukanganisa kwevanhu nemidziyo. kukonzera kukuvadza; zvimwe. 4. Nzvimbo yakachengeteka Nzvimbo yekudzivirira yekudzivirira inoreva kugadzika kwakanaka pakati pemakasi emuchina wese nemidziyo mukamuri yekombuta uye muviri (casing) wemidziyo yekubatsira senge mota uye air conditioners uye pasi, iyo isingafanirwe kunge yakakura kupfuura 4 ohms. Kana ma insulators emhando dzakasiyana dzemagetsi mukamuri yemidziyo akakuvadzwa, zvinokonzeresa kutyisidzira kuchengetedzeka kwemidziyo nevashandisi nevashandi vekuchengetedza. Naizvozvo, iyo casing yemidziyo inofanirwa kuve yakavimbika pasi. 5. Ivhu rekudzivirira mheni Ndokunge, iyo yekugadzika kwemheni yekudzivirira system mukamuri yekombuta kazhinji inovigwa pasi pevhu nemitsara yakachinjika yekubatanidza uye yakatwasuka mirwi yekumisa, kunyanya kutungamira mheni kubva kune mheni inogashira mudziyo kuenda kune yepasi, iyo isingafanirwe kunge yakakura kupfuura gumi. ohms. Chishandiso chekudzivirira mheni chinogona kukamurwa kuita zvikamu zvitatu zvakakosha: mudziyo wekumisa mweya, wepasi-conductor uye mudziyo wepasi. Mudziyo wekupedza mhepo isimbi conductor inogamuchira ikozvino mheni. Muchigadziriso ichi, chete pasi-conductor yemheni inosunga inosungirirwa kune inogadzika mhangura bar mumagetsi ekugovera kabhineti. Kuramba kwepasi kunodiwa kuve kushoma pane kana kuenzana ne4Ω.
