Isisekelo sokuvikela umbani sezibani zomgwaqo ezisebenza ngamandla amakhulu

I. Dala Isiteshi Sokukhipha Ugesi Somhlaba Esithembekile

Amadivayisi okumisa inhlabathi afakwa kanye nokwakhiwa kwesisekelo sezibani zesignali zethrafikhi ze-AC, kanti ama-electrode okumisa inhlabathi ayinsimbi egobile kanye nensimbi egobile. Induku ngayinye ishayelwa emhlabathini ngezinsimbi ezimbili ezigobile ezingama-2.5 m ubude, okungenani ama-5 m ukuqhelelana. Bese zixhunywa ngokuvundlile ngensimbi egobile engama-40×4 mm egobile ukuze zakhe igridi yokumisa inhlabathi emise okwendandatho. Amajoyinti ahlanganisiwe ensimbi egobile ahlanganiswa futhi ambozwe nge-asphalt ukuvimbela ukugqwala. Ukujula kokungcwaba kulawulwa ngaphansi kwama-0.7 m, kugwema izendlalelo zenhlabathi ezingahambi kahle njengetshe letshe kanye nesihlabathi esomile. Ukugcwalisa i-backfill nge-ejenti yokunciphisa ukumelana ezindaweni zenhlabathi eyomile kuzonciphisa ukumelana komhlaba. Ikhonkrithi eqinisiwe ayikwazi ukusetshenziswa njengokufaka esikhundleni esisodwa sama-electrode okumisa inhlabathi azinikele. Ukuqhuba kwekhonkrithi akuzinzile futhi akukwazi ukukhipha ngokushesha i-voltage ephezulu ngesikhathi sokushaya kombani.

II. Ukuhlanganiswa Kwemishini Yonke Ukuze Kugwenywe Ingozi Yokwehluleka Komehluko Ongase Ube Khona

Ngemva kokuba igridi yokumisa umhlabathi seyakhiwe, izinti, amabhokisi ezignali, izindlu zezibani zesignali, kanye nemizila yensimbi kumele ziboshwe ngesibopho esivamile se-equipotential. Izisekelo zezinti zensimbi kumele zixhunywe ngokuthembekile ngqo ensimbini eyisicaba yokumisa umhlabathi. Amabhokisi okusabalalisa kanye nezindlu zesignali kumele zixhunywe ezindaweni ezinkulu zokumisa umhlabathi kusetshenziswa izintambo zokumisa umhlabathi eziphuzi-luhlaza okotshani. Izintambo zokumisa umhlabathi zethusi kumele zixhunywe kuzo zombili izinhlangothi zemizila yensimbi ukuze kuvinjelwe ukuthi imizila ingami ekubangeleni i-voltage. Wonke amagridi okumisa umhlabathi endaweni yokumisa umhlabathi kumele axhunywe ukuze enze umzimba owodwa ongaba khona kuyo yonke indawo yokumisa umhlabathi. Lokhu kuvimbela ukugoba ngenxa yokwehluka kwamandla kagesi phakathi kwemishini ehlukene nomhlabathi ngesikhathi sezimvula ezinkulu futhi kuvimbela ukulimala kwamaphaneli okukhanya e-LED kanye namabhodi okulawula. Izibani zesignali ezinezimbobo zepulasitiki nazo zidinga ukuthi amabhuleki ensimbi angaphakathi amiswe; izintambo zangaphakathi zama-terminal okumisa umhlabathi azikwazi ukushiywa.

III. Ukufakwa Kwezivikeli Zokukhuphuka Ukuze Kunqunywe Ukushaya Kombani Okubangelwa Yizinto Ezimbi

Amadivayisi okuvikela ukukhuphuka komoya kufanele ahlinzekwe kuzo zombili izinhlangothi zemigqa yokungena kwamandla kagesi kanye nemigqa yokuxhumana yesignali. Isivikelo sokukhuphuka esiyinhloko sixhunywe ngokwehlukana nezintambo ezibukhoma, ezingathathi hlangothi, kanye nezintambo zomhlabathi endaweni yokungena kwamandla kagesi kagesi engu-220V ebhokisini lokusabalalisa isignali yethrafikhi. Kukhebula lenethiwekhi kanye nomugqa wokulawula wokuxhumana ongu-485, faka isivikelo sokukhuphuka komoya wesignali bese uxhuma igobolondo lensimbi lekhebula lenethiwekhi elivikelwe phansi kuzo zombili izinhlangothi. Zonke izintambo zomhlabathi zesivikelo sokukhuphuka komoya zixhunywe ngqo kuma-mains aphansi, futhi ubude bomthofu bunqunyelwe ngaphakathi kwamamitha angu-0.5 ukuze kuncishiswe i-voltage eseleyo. Okubalulekile kufanele kunikezwe ekuguquleni iziphambano zekhebula eziphezulu zibe yizintambo zomsele ongaphansi komhlaba. Izintambo eziphezulu zithinteka ukushaya kombani onamandla aphezulu. Ukufakwa kwezintambo ngaphansi komhlaba kunciphisa kakhulu amathuba okungena kombani. Izinsika zokungena kanye nezindawo zokuphuma kwekhebula kumele zivikelwe kahle amanzi futhi zivalwe ukuze kuvinjelwe amanzi emvula ukuthi angonakalisi iziphetho zesivikelo sokukhuphuka komoya.

IV. Ukulinganisa Ukumelana Nokumisa Inhlabathi Okuvamile Nokunakekelwa Ngemva Kokwakha

Uma ukwakhiwa sekuqediwe, ukumelana nokumisa umhlabathi kuhlolwa ngesihloli sokumelana nokumisa umhlabathi.Izibani zomgwaqo zikamasipalaEzimpambanweni zomgwaqo zinokumelana okujwayelekile kokumisa umhlabathi okungu-≤4Ω. Uma ukumelana kuphakeme kunejwayelekile, kufanele kwengezwe ama-electrode engeziwe okumisa umhlabathi noma izinto ezinciphisa ukumelana. Ngaphambi kwenkathi ngayinye yemvula, hlola ukuhlola ukugqwala ezindaweni zokushisela zensimbi eziyisicaba, izintambo zokumisa umhlabathi ezikhululekile noma ezihlukanisiwe, kanye nokushintsha noma ukwehluleka kwezivikelo zokukhuphuka kwamanzi. Imisele yokumisa umhlabathi ingaqoqa amanzi ngesikhathi semvula. Yisuse ngokushesha ngemva kwenkathi yemvula ukuze ama-electrode okumisa umhlabathi angahlali emanzini isikhathi eside futhi agqwale. Ezimpambanweni ezindala ezilungiswayo, amagridi okumisa umhlabathi agqwalile kudingeka avuselelwe, futhi izintambo zokumisa umhlabathi ezigugile zidinga ukushintshwa ukuze kuvinjelwe ukusha kwemishini kanye nezingozi zokushaqeka kukagesi ezibangelwa ukwehluleka kokumisa umhlabathi.
