Chingwe cha kuwala sichifuna njira zapadera zotetezera mphezi, koma ngati kuwala kwakunja kuli pamwamba, gawo lachitsulo la fiber fiber liyenera kukhazikika. Kuteteza kwa awiri opotoka kumakhala koyipa, kotero kuthekera kwa kugunda kwamphezi kumakhala kwakukulu. Mizera yotereyi iyenera kuyikidwa mu khola lotchingidwa ndi waya, ndipo mbiya ya waya yotetezedwa iyenera kukhazikika bwino; imathanso kuyikidwa kudzera mu mapaipi achitsulo, ndipo mapaipi azitsulo ayenera kusungidwa pamzere wonsewo. Kulumikizana kwamagetsi, ndipo malekezero onse a chitoliro chachitsulo ayenera kukhala okhazikika.(2) Ndi njira yabwino yokhazikitsira chomangira mphezi pamzere wa chizindikiro kuti mupewe mphezi yolowera. Kwa machitidwe ophatikizira maukonde, zida zapadera zotetezera mphezi zitha kukhazikitsidwa mizere ya ma network isanalowe mu rauta ya WAN; zida zoteteza mphezi zokhala ndi mawonekedwe a RJ45 zimayikidwa pa switch ya msana, seva yayikulu, ndi zolowera zolowera panthambi iliyonse ndi seva motsatana (Monga RJ45-E100). Kusankhidwa kwa chomangira chizindikiro kuyenera kuganizira mozama mphamvu yamagetsi yogwirira ntchito, kuchuluka kwa ma transmission, mawonekedwe a mawonekedwe, ndi zina zotero. Chomangirira chimalumikizidwa makamaka pamndandanda pa mawonekedwe a zida pamapeto onse a mzere.① Ikani chomangira chizindikiro cha doko limodzi la RJ45 pamalo olowetsa seva kuti muteteze seva.② Ma 24-port network switch amalumikizidwa motsatizana ndi 24-port RJ45 zomangira ma siginecha kuti apewe kuwonongeka kwa zida chifukwa cha mphezi kapena kusokonezedwa ndi ma elekitiroma kulowa mopotoka.③ Ikani doko limodzi la RJ11 chomangira chizindikiro pa DDN yodzipatulira yolandirira chipangizo kuti muteteze zida pa mzere wodzipatulira wa DDN.④ Ikani coaxial port antenna feeder mphezi chomangirira kutsogolo kwa satellite yolandila zida kuti muteteze zida zolandirira.(3) Kutetezedwa kwa mphezi kwa chipinda chowunikira① Ikani chipangizo chotetezera mphezi ya kanema kumapeto kwa chojambulira cha hard disk chojambulira kapena gwiritsani ntchito bokosi loteteza mphezi la vidiyo yokhazikika, madoko 12 ndi otetezedwa mokwanira komanso osavuta kukhazikitsa.② Ikani chipangizo choteteza mphezi (DB-RS485/422) kumapeto kwa mzere wolowera kumapeto kwa matrix ndi chogawa chamavidiyo.③ Mzere wa telefoni wa chipinda cha pakompyuta umagwiritsa ntchito chipangizo chotetezera mphezi, chomwe chimalumikizidwa motsatizana ndi chingwe cha foni kutsogolo kwa foni, chomwe chimakhala chosavuta kukhazikitsa ndi kukonza.④ Ikani chipangizo chotetezera chizindikiro cha mphezi pamalo ofikira mzere wa chizindikiro kutsogolo kwa chipangizo cha alamu kuti mupereke chitetezo chogwira mtima cha mphezi pa mzere wa chizindikiro cha chipangizo cha alamu.Zindikirani: Zida zonse zotetezera mphezi ziyenera kukhala zokhazikika bwino. Posankha zipangizo zotetezera mphezi, chidwi chiyenera kuperekedwa ku mawonekedwe a mawonekedwe ndi kudalirika kwa nthaka. Mawaya apadera oyika pansi ayenera kukhazikitsidwa m'malo ofunikira. Kuti mukhale kutali momwe mungathere, patukani pansi.4. Equipotential kugwirizana mu kompyuta chipindaPansi pa anti-static floor ya chipinda cha zida, konzani mipiringidzo yamkuwa 40 * 3 pansi kuti mupange basi yotsekeka. Dulani chipolopolo chachitsulo cha bokosi logawa, malo opangira magetsi, malo omangira, chipolopolo cha nduna, zitsulo zotchinga waya, zitseko ndi mawindo, ndi zina zotero. zida zadongosolo, ndi chimango chodzipatula pansi pa anti-static floor. Mfundo equipotential grounding amapita ku busbar. Ndipo ntchito equipotential kugwirizana waya 4-10mm2 mkuwa pachimake waya bawuti ananamizira waya kopanira monga zakuthupi kugwirizana. Panthawi imodzimodziyo, pezani chitsulo chachikulu cha nyumbayo mu chipinda cha makompyuta, ndipo chimatsimikiziridwa kuti chikugwirizana bwino ndi chomangira mphezi pambuyo poyesedwa. Gwiritsani ntchito zitsulo zozungulira zozungulira 14mm kuti mulumikizane ndi basi yoyambira nayo kudzera panjira yosinthira chitsulo chamkuwa. Equipotential imapangidwa. Cholinga chogwiritsira ntchito gululi wogwirizanitsa pansi ndikuchotsa kusiyana komwe kungakhalepo pakati pa ma grids am'deralo ndikuonetsetsa kuti zipangizozo sizikuwonongeka ndi kumenyana ndi mphezi.5. Grounding grid kupanga ndi kapangidweKuyika pansi ndi chimodzi mwazinthu zofunika kwambiri paukadaulo woteteza mphezi. Kaya ndi kugunda kwachindunji kapena mphezi yolowera, mphamvu yamagetsi imalowetsedwa pansi. Chifukwa chake, pazida zoyankhulirana zodziwika bwino (zizindikiro), ndizosatheka kupewa mphezi modalirika popanda dongosolo lokhazikika komanso lokhazikika. Chifukwa chake, pamaneti oyambira omanga omwe ali ndi kukana koyambira> 1Ω, ndikofunikira kukonza molingana ndi zofunikira kuti mutsimikizire kudalirika kwa dongosolo lokhazikitsira chipinda cha zida. Malinga ndi momwe zinthu zilili, malo ogwira ntchito a gridi yoyambira pansi komanso mawonekedwe a gridi yoyatsira amasinthidwa ndikukhazikitsa mitundu yosiyanasiyana ya ma gridi oyambira (kuphatikiza matupi opingasa ndi matupi oyimirira) m'chipinda cha makompyuta.Mukamagwiritsa ntchito chipangizo chokhazikika, chokhazikika chokhazikika sichiyenera kukhala chachikulu kuposa 1Ω;Chida chapadera choyika pansi chikagwiritsidwa ntchito, mtengo wake wokhazikika suyenera kukhala wamkulu kuposa 4Ω.Zofunikira zazikulu ndi izi:1) Pangani gululi kuzungulira nyumbayo kuti mutsirize chipangizo chothandizira kwambiri chokhala ndi zida zochepa komanso kutsika mtengo wokhazikitsa;2) Kuyika kukana zofunika zofunika R ≤ 1Ω;3) Thupi lokhazikika liyenera kukhazikitsidwa pafupi ndi 3 ~ 5m kutali ndi nyumba yaikulu yomwe chipinda cha makompyuta chili;4) Thupi loyanjanitsa ndi loyima liyenera kukwiriridwa pafupi ndi 0.8m pansi pa nthaka, thupi loyimirira liyenera kukhala lalitali 2.5m, ndipo thupi loyimirira liyenera kukhazikitsidwa 3 ~ 5m iliyonse. The grounding thupi ndi 50 × 5mm otentha-kuviika kanasonkhezereka lathyathyathya chitsulo;5) Pamene mauna pansi ndi welded, malo kuwotcherera ayenera ≥6 nthawi kukhudzana mfundo, ndi kuwotcherera mfundo ayenera kuthandizidwa ndi mankhwala odana ndi dzimbiri ndi odana ndi dzimbiri;6) Ukonde m'malo osiyanasiyana uyenera kuwotcherera ndi zitsulo zazitsulo zazitsulo zambiri zomanga nyumba pa 0.6 ~ 0.8m pansi pa nthaka, ndikuchiritsidwa ndi mankhwala oletsa dzimbiri ndi anti- dzimbiri;7) Pamene nthaka conductivity ndi osauka, njira atagona kukana kuchepetsa wothandizila adzakhala anatengera kuti grounding kukana ≤1Ω;8) The backfill ayenera kukhala dongo latsopano ndi bwino madutsidwe magetsi;9) Kuwotchera ndi ma point angapo okhala ndi maziko a nyumbayo, ndikusunga malo oyeserera.Zomwe zili pamwambazi ndi njira yachikhalidwe yotsika mtengo komanso yothandiza. Malinga ndi momwe zinthu zilili, gridi yoyambira imathanso kugwiritsa ntchito zida zatsopano zoyambira, monga kusamalidwa kopanda ma electrolytic ion grounding system, gawo lokhazikika lokhazikika, ndodo yachitsulo yokhala ndi mkuwa yanthawi yayitali ndi zina zotero.
