Uyini Umehluko Phakathi Kwamabhokisi Okufakazela I-flameproof kanye Nokwenyuka Kwezokuphepha Kokuqhuma

Izinhlobo Zobufakazi Bokuqhuma:

Izindlela zokuvikela ukuqhuma zokwandisa ukuphepha (Ex kanye) futhi lingashi (Ex d) izivalo zihluka kakhulu.

Uhlobo lwe-Flameproof:

Indlela yokuvikela ilangabi ihlanganisa izingxenye ezivalekile ezingase zikhiqize ama-arc noma izinhlansi ngesikhathi sokusebenza okuvamile ngaphakathi kwendawo ebiyelwe eqinile.. Le ndawo ebiyelwe imelana nezingcindezi zokuqhuma ngaphandle kokulimala, ukuqinisekisa ukuthi amalangabi namazinga okushisa ayingozi adalwa ukuqhuma ngaphakathi akudluliseli ngaphandle. Iqinisekisa ukuthi lezi ziyacishwa futhi zipholile lapho zidlula endaweni engashi, ukuvimbela ukuthungela eziqhumayo amagesi ngaphandle kwendawo ebiyelwe.

Uhlobo Lokuphepha Olunyusiwe:

Ku ukwanda kokuphepha (Ex kanye) ezivalekile, akukho ukukhiqizwa kwenhlansi noma amazinga okushisa ayingozi ngesikhathi sokusebenza okuvamile. Izinyathelo ezengeziwe zithathwa ukuthuthukisa ukuphepha nokwethembeka.

Izikulufu:

Kungani kunezikulufu eziningi kangaka phakathi angashi ezivalekile, kodwa hhayi ezinhlotsheni zokuphepha ezengeziwe?

Izivalo ezingenamlilo zidinga izinga eliphezulu lokunemba ekubekezeleleni igebe ukuze kuvinjelwe ukuqhuma kwangaphakathi ekushiseni amagesi aqhuma angaphandle.. Izikulufu ezengeziwe ziqinisekisa ama-seams aqinile nokuphepha okukhulu. Kungakho izivalo ezingashi zinezikulufu eziningi.

Ukuphepha okungeziwe kugxile ezingeni lokuvikela. Ukuvalwa ngempumelelo ngezikulufo ezine nje kwanele.

Izingxenye:

Izivalo ezingangenwa umlilo azikhawuli mayelana nezingxenye zangaphakathi ngoba zingakwazi ukumelana nanoma yimaphi ama-arcs noma izinhlansi ngaphakathi.. Uma nje igobolondo langaphandle lingakwazi ukumelana nokucindezela kokuqhuma ngaphandle kokulimala, iqinisekisa ukuthi amalangabi namazinga okushisa aphezulu akhiqizwa ngaphakathi kuyacishwa futhi kuyapholiswa lapho kudlula ilunga elingashi., ukuvimbela ukuthungela kwangaphandle.

Izivalo ezengeziwe zokuphepha kufanele ziqale ziqinisekise ukuthi izinto zangaphakathi azikhiqizi izinhlansi, amazinga okushisa ayingozi, noma ama-arcs. Kube sekuthathwa ezinye izinyathelo zokuvikela ukuze kuthuthukiswe ukuphepha nokwethembeka.

Ukuhambisana:

Ngokwesibonelo, i-circuit breaker eyenzelwe indawo evalekile engashi ayikwazi ukusetshenziswa endaweni ebiyelwe yokuphepha eyengeziwe. Nokho, ukuguqula indawo ebiyelwe yokuphepha eyengeziwe ibe ngengashi kuvumelekile.

Ngakho-ke, uhlobo olufanele lwendawo evikela ukuqhuma kufanele ikhethwe ngokusekelwe ezidingweni zangempela, futhi ukushintshwa akufanele kwenziwe ngokunganaki.
