Amasu Okufaka Uthuli Ekufakweni Kukagesi
Isingeniso
Ukubeka phansi kuyisici esiyisisekelo sokufakwa kukagesi esiqinisekisa ukuphepha, ukuzinza kohlelo, kanye nokusebenza kahle kwezinhlelo zikagesi. Kuvimbela ukushaqeka kukagesi, umonakalo wemishini, kanye nezingozi zomlilo ngokuhlinzeka ngendlela yokuthi imisinga kagesi elahlekile ihlakazeke emhlabeni. Amasu okubeka phansi ayahlukahluka ngokusekelwe ezidingweni ezithile zokufakwa, futhi ahlanganisa uhla lwemikhuba, izinto zokwakha, kanye nezindinganiso.
Ukubaluleka Kokubeka phansi
Ukubeka phansi kufeza imisebenzi eminingana ebalulekile:
1. Ukuphepha: Kuvimbela ukushaqeka kukagesi ngokuqinisekisa ukuthi noma yimiphi imigudu yephutha iqondiswa kude nabasebenzisi futhi iyiswe emhlabathini ngokuphephile.
2. Ukuvikelwa Kwemishini: Ukufakwa kwesisekelo esifanele kusiza ekuvikeleni imishini kagesi neye-elekthronikhi ekukhuphukeni nasekuphazamisekeni.
3. Ukuzinza Kwesistimu: Ukubeka phansi kusiza ekugcineni amazinga kagesi ngaphakathi kwesistimu, okufaka isandla ekuzinzeni kwayo konke.
4. Ukuthobela imithetho: Ukunamathela ezindinganisweni zezwe nezamazwe ngamazwe kubalulekile ekulandeleni imithetho nemithetho.
Izinhlobo ze-Grounding Systems
Kusetshenziswa izinhlelo ezahlukene zokumisa inhlabathi kuye ngokuthi kusetshenzisweni, uhlobo lomthwalo, kanye nezimo zemvelo. Izinhlobo eziyinhloko zifaka:
1. Ukuqina Okungaguquki noma Ukusekela Imishini
Lokhu kuhilela ukuxhuma izingxenye zemishini ezingewona ugesi emhlabeni, ukuqinisekisa ukuthi uma kwenzeka iphutha, imishini ayibi yingozi yokushaqeka. Ukufakwa kwesisekelo esingaguquki kubalulekile kumadivayisi anjengezivalo zensimbi, izinhlelo zemibhobho, nezinye izingxenye eziqhuba ugesi ezingase zithintane nezingxenye zikagesi.
2. Uhlelo Lokumisa Inhlabathi
Ukusekela uhlelo kubhekisela ekusekeleni izingxenye zesistimu kagesi njengephuzu elingathathi hlangothi lama-transformer, ama-generator, noma iphuzu eliphakathi lesistimu yokuphakelwa kwamandla. Inhloso yalo eyinhloko ukulawula i-voltage ngesikhathi sokusebenza okuvamile kanye nezimo zamaphutha.
3. Ukuvikela Umbani
Le ndlela yokufaka isisekelo iklanyelwe ukuvikela izakhiwo ekushayweni umbani ngokuhlinzeka ngendlela eqondile yokusabalalisa amandla kagesi emhlabathini. Ihilela ukusetshenziswa kwezinduku zombani, ama-conductor, kanye nama-electrode omhlaba.
Izingxenye Zokugawula
1. Izinduku Zomhlabathi
Izinduku zomhlaba zidonswa emhlabeni ukuze zinikeze ukuxhumana okungokoqobo phakathi kohlelo lukagesi nomhlabathi. Ngokuvamile zenziwe ngethusi, insimbi eqinisiwe, noma insimbi engagqwali. Ukujula kanye nenani lezinduku zomhlabathi kuncike ekuqhutshweni kwenhlabathi kanye nezidingo zesistimu.
2. Izintambo Eziphansi
Izintambo eziphansi, ezaziwa nangokuthi ama-grounding conductor, zixhuma uhlelo lukagesi noma imishini ku-electrode ephansi. Kumelwe zibe nosayizi ofanele ukuze ziphathe amaza angase abe khona ngaphandle kokushisa ngokweqile.
3. Amapuleti Omhlaba kanye Nama-Mats
Ezindaweni lapho izinduku zokushayela phansi zingasebenzi khona, amapuleti noma omata bomhlaba bangasetshenziswa. Lezi yizindawo ezinkulu zokuhambisa umoya ezigqitshwe emhlabathini, okunikeza indlela ephansi yokumelana nomhlaba.
4. Ama-Bonding Jumpers
Ama-jumper okubopha asetshenziswa ukuqinisekisa ukuthi zonke izingxenye zikagesi nezensimbi zisezingeni elifanayo lomhlabathi, okuvimbela umehluko wamandla kagesi angaholela ezingozini zokushaqeka.
Amasu Okwehlisa
1. Ukusekela Ngephuzu Elilodwa
Ukufakwa kwesisekelo sendawo eyodwa kuhilela ukuxhumanisa zonke izixhumanisi zomhlaba ohlelweni nephuzu elilodwa. Lokhu kunciphisa amathuba okuthi kube nezihibe zomhlaba, okungadala umsindo kanye nokuphazamiseka okubaluleke kakhulu ekufakweni kwe-elekthronikhi okubucayi.
2. Ukusekela Okunezindawo Eziningi
Ezinhlelweni ezinkulu, kungadingeka izindawo eziningi zokumisa umhlabathi ukuze kuncishiswe ukumelana nokuqinisekisa ukuthi isisekelo sisebenza kahle. Uhlelo ngalunye noma ingxenye yalo inokuxhumana komhlabathi, okusiza ekuhlakazeni amaza okuphazamiseka ngendlela ephumelela kakhulu.
3. Ukusikwa Kwe-Mesh
Ukufakwa kwe-mesh kuhilela ukuxhumanisa izindawo eziningi zomhlabathi esakhiweni esifana ne-mesh. Le ndlela ivame ukusetshenziswa ekufakweni kwe-high voltage nasezindaweni ezinomsebenzi omkhulu wombani. Iqinisekisa uhlelo oluqinile lokufakwa kwe-ground olukwazi ukusingatha imisinga emikhulu yephutha.
Amazinga Nemithethonqubo
Ukunamathela ezindinganisweni kanye nemithethonqubo kubalulekile ukuze kuqiniswe kahle. Izindinganiso ezibalulekile zifaka:
1. Ikhodi Kagesi Kazwelonke (i-NEC)
I-NEC inikeza izidingo zokufakwa kukagesi e-United States, okuhlanganisa neziqondiso eziphelele zokufaka isisekelo.
2. Izindinganiso ze-IEEE
I-Institute of Electrical and Electronics Engineers (IEEE) inikeza amazinga ahlukahlukene emikhubeni yokufaka isisekelo, okuhlanganisa ne-IEEE 142 (Green Book) okuyiyona ndlela eyinhloko yokufaka isisekelo.
3. IKhomishini Yobuchwepheshe Be-Electrotechnical Yomhlaba Wonke (i-IEC)
I-IEC ihlinzeka ngezindinganiso zomhlaba wonke zokufaka isisekelo, okuhlanganisa ne-IEC 60364 enikeza iziqondiso mayelana nokufakwa kwezintambo kanye nokufaka isisekelo kokufakwa kukagesi.
4. Ukuphathwa Kwezokuphepha Nezempilo Emsebenzini (i-OSHA)
Imithethonqubo ye-OSHA iqinisekisa ukuphepha endaweni yokusebenza, okuhlanganisa nezidingo zokufakwa kwesisekelo esifanele ezindaweni zezimboni nezentengiselwano.
Ukufakwa Izindlela Ezinhle Kakhulu
1. Ukuhlolwa Kwendawo
Ngaphambi kokufakwa, ukuhlolwa okuphelele kwendawo kubalulekile ukuze kunqunywe ukumelana nenhlabathi kanye nendlela engcono kakhulu yokufaka umhlabathi. Ukuhlolwa kokumelana nenhlabathi kungaqondisa ukukhethwa kwama-electrode afanele okufaka umhlabathi kanye nokubekwa kwawo.
2. Usayizi Owanele
Ama-grounding conductor kumele abe nobukhulu obuphelele ukuze aphathe amaphutha angaba khona ngaphandle kokushisa ngokweqile. Lokhu kudinga ukubalwa ngokucophelela ngokusekelwe ezicacisweni zesistimu.
3. Ukuhlolwa Okuvamile Nokunakekelwa
Izinhlelo zokumisa umhlabathi kumele zihlolwe njalo futhi zigcinwe ukuze kuqinisekiswe ukuthi zisebenza kahle. Lokhu kuhlanganisa ukuhlolwa kokuqhubeka, ukulinganisa ukumelana, kanye nokuhlolwa okubonakalayo.
4. Ukuxhumana Okufanele
Zonke izixhumanisi zokusekela umhlabathi kumele zivikeleke, zingagqwali, futhi zifinyeleleke kalula ukuze zihlolwe. Ukusetshenziswa kahle kwezixhumi kanye nezinamathiselo zemishini kubalulekile.
5. Imibhalo
Kubalulekile ukuthola imibhalo enembile nesesikhathini yesistimu yokumisa umhlabathi. Lokhu kufaka phakathi ama-schematics, imiphumela yokuhlolwa, kanye namarekhodi okugcinwa.
Isiphetho
Ukufaka inhlabathi phansi kuyisici esibalulekile sokufakwa kukagesi, okuvikela abantu kanye nemishini ezingozini zikagesi. Ukuqonda izinhlobo zezinhlelo zokufaka phansi phansi, izingxenye ezihilelekile, kanye nemikhuba emihle yokufaka kuqinisekisa uhlelo lokufaka phansi oluphephile nolusebenzayo. Ukunamathela ezindinganisweni kanye nokugcinwa njalo kuqinisa ukuthembeka nokuphepha kokufakwa kukagesi. Njengoba ubuchwepheshe kanye nemithethonqubo zishintsha, ukuhlala unolwazi futhi uhambisana namasu okufaka phansi phansi kusalokhu kuyisici esibalulekile sobunjiniyela kagesi kanye nemikhuba yokufaka.
