METHOD FOR TESTING COMPOUNDS OF EXPLOSION-PROOF ELECTRICAL EQUIPMENT WITH ENCAPSULATION TYPE OF PROTECTION
Abstract
The use of electrical energy in potentially explosive atmospheres involves various particularities, fact for which there have been raised a lot of issues concerning the design, construction and exploitation of electrical equipment and installations intended to be used in these atmospheres. This paper presents the explosion protection principles implemented for the type of protection encapsulation ?m? which are based on the adoption of certain separations between the encapsulated circuits and the other circuits, by including them in a compound. The paper describes the test method for water absorbtion of compounds for explosion-proof electrical equipment with type of protection encapsulation ?m?.
