Earthing nokuphepha kagesi

Noma iyiphi idivayisi kagesi zingase zephule. Uma nje wayeka ukusebenza - kungcono singakabi sibi kangako. Okubi nakakhulu, uma imiphumela ukwahluleka kwema- voltage kagesi ku izakhi nomklamo walo ukuthi umsebenzisi uyazicabangela ephephile. Engaqondile wathinta ngale ndaba, umuntu ngaphansi ngogesi, kungenziwa abalimala noma ngisho nakakhulu ...

Uyini umhlaba zokuzivikela

Lapho kwangaphakathi wire zokugwema ukuphuka sezivuma uthinte izindlu kagesi noma enye idivayisi, kuleso simo yokugcina kungaba ingozi yokufa, engabonakali, futhi ngenxa yalokho isibili esabekayo. Ukuze ugweme izimo ezinjalo, isicelo amadivaysi isisekelo. bekhuphuka silula, kodwa ngokuphelele kumelwe ahlangabezane nezimfuneko eziningana.

Imishini zangaphandle, futhi yiphi impahla, zitholakala ezindaweni ezimanzi futhi kumele kufakwe earthing hlangothi, uma voltage ukunikezela idlula 42 V AC noma 110 V DC. Kuyefana nasendleleni sensimbi zonke izakhi bukhoma amathuluzi amandla, amabhokisi, amabhodi izakhiwo, lapho ikhebula.

Yini liqukethe phansi

kudivayisi Earthing inezingxenye ezimbili eziyinhloko.

Eyokuqala yalezi ubizwa ngokuthi isisekelo, futhi ngokuvamile kuba isakhi zemvelo, ezifana ama-valve, namapayipi wangcwatshwa kanye neminye imininingwane ukuqinisekisa oxhumana onokwethenjelwa futhi ngokuphindaphindiwe emhlabathini. Uma, ngenxa Kwezinye izimo ezakhiwe ezinjalo ziyatholakala yini noma azitholakali, sebenzisa yokufakelwa kudivayisi isisekelo. Ziyakwazi engeli steel, wangcwatshwa emhlabathini kumuntu ka cm okungenani 60 ukujula kusukela usayizi ubuso 5 cm hhayi ngaphansi kuka 4 mm obukhulu. Ubude ngasinye salezi zici kufanele okungenani 3 metres, baya ezijulile emhlabathini, khona ashiselwe nalokho emapheshana steel, lapho yasibamba Kwenziwa babashayeli, okusho ukuthi ingxenye isakhiwo enikeza ukuphepha kagesi yesibili.

isisekelo Izidingo

I ukumelana idivayisi isisekelo kufanele sibe ongatheni, ngakho izidingo nokwethenjelwa contact kuphezulu kakhulu. Inhloso Its main ukwakha izimo elibangelwa ukwehluleka amandla uma kwenzeka uhlangana nabo conductive ingxenye izakhi okuyinto ngaphansi kwezimo ezivamile akufanele nginomdlandla. On ngokushesha kangakanani ngeke EPO, ngokuvamile kuxhomeke ekutheni ukuphila komuntu.

Ground ukulawula isimo

Ukuze ulawule degree of kagesi, nesilinganiso gqwa senziwa zedivayisi isisekelo. Okwakushiwo bomzimba walo Inqubo ukunquma ukumelana langempela zazo esimweni esiphuthumayo kuyoba zamanje. Ngenxa yale njongo amadivayisi ezikhethekile, ephelele iphenya nokulawula kuyinto ngobuciko Ohm amamitha (isib, MRU-101).

Ngesikhathi amabhizinisi of meet kagesi izikhulu ezithile, ngokuvamile, kuyinto induna amandla unjiniyela, induna amasevisi ezempilo, yebo, ukuphathwa. In efulethini lakhe, indlu live noma isakhiwo wangasese amadivayisi isisekelo zilawulwa abanikazi impahla.

Qaphela futhi baqaphe!
