THE PARTICULARITIES OF ELECTRICAL EQUIPMENT WITH TYPE OF PROTECTION FLAMEPROOF ENCLOSURE USED IN POTENTIALLY EXPLOSIVE ATMOSPHERES GENERATED BY HYDROGEN
Abstract
Electrical equipment that operates in a potentially explosive atmosphere, have characteristics specially designed for operation in this area. For security reasons, it is essential that the integrity of these special features be preserved in these areas throughout the life of the installation. Using electric equipment in potentially explosive atmospheres brings forward several particularities therefore the problems that appear during the design, construction and operation of electrical devices and installations brings forward numerous difficulties, their approach requiring special attention considering all the technical, economical and labor safety aspects. The purpose of the paper is to reveal the particularities of electrical equipment with type of protection flameproof enclosure design to be used in potentially explosive atmospheres generated by hydrogen. Evaluation of explosion-proof protected electrical equipment in scope of certification is extremely important considering the risk of explosion that has to be minimized in order to ensure life safety and health of workers and to prevent damaging of property and the environment, as well as free movement of goods when they meet the essential safety requirements at European level.
