Imikhiqizo
Ibhokisi elivalekile lensimbi le-ATEX elivikela ukuqhuma
Incazelo Yomkhiqizo
Ukuvikela ukuqhuma (nobufakazi bokuqhuma okupeliwe) kungamabhokisi okuhlangana aqinile ukuze asetshenziswe ezindaweni eziyingozi.Bafaka izingxenye zikagesi ezihlukahlukene ezifana nalezi: amabhulokhi wokugcina, amaswishi, ama-transformer, ama-relay namanye ama-arching & sparking devices.Lawa mabhokisi akhiwe ukuze aqukathe ukuqhuma kwangaphakathi okuvela kumagesi, umhwamuko, uthuli nemicu ukuze kugcinwe umoya ozungezile ophephile.Ziyakwazi ukumelana nokugqwala futhi zigcina ukubekezelela amazinga okushisa aphezulu kakhulu.Lezi zindawo ezivalekile ezingashi ziyisixazululo esifanelekile sezindawo eziyingozi.Njengoba zivikela ukuqhuma, zizoqukatha noma yikuphi ukuqhuma kwangaphakathi kusukela ekusakazeni endaweni yangaphandle, ngaleyo ndlela kuvimbele ukulimala kanye nokulinyazwa kwempahla.
Izindawo ezivalekile ezingaqhumi nezingashi zihlukaniswa ngezilinganiso zokuvikela ezihlukene, kuye ngendawo nezinga lokuvikela ezikunikezayo.Lezi zilinganiso zisekelwe kumazinga eNational Electrical Manufacturers Association (NEMA), kanye nezinga lamazwe ngamazwe elingu-EN 60529 for Ingress Protection (IP) elibonisa izinga lokuvikelwa ezingozini zikagesi njengokugqwala, uthuli, imvula, ukuchaphazeka namanzi aqondiswe ngepayipi. kanye nokwakheka kweqhwa.
Izivalo ezingaqhumisi ziklanywe ngama-flange anwetshiwe apholile futhi aqukethe ukuqhuma okungaphakathi kwendawo ebiyelwe.Ngakho-ke, noma iyiphi i-arc kagesi engaba khona ngeke isabalale emkhathini wangaphandle oqhumayo.
● Iphephile futhi inokwethenjelwa endaweni eneziqhumane.
● Indawo evikela ukuqhuma isiza bonke abantu abasebenza endaweni eyingozi ukuthi bahlale bephephile uma kwenzeka ingozi.Kuphinde kunciphise umonakalo ongase ube khona.
● Izinto ezisetshenziswa endaweni ebiyelwe zihlala isikhathi eside.Inokumelana nomthelela ophezulu.
● Ihambisana nezindinganiso eziphakeme kakhulu zokuphepha.
● Inezinga eliphakeme lokuvikela.
