Abstract
Изобретение относитс к эл4:;г- ротехнике, в частности к корпусам взрывозащищенного электрооборудовани , предназначенного дл эксплуатации во взрывоопасных производствах. Цель изобретени - снижение материалоемкости оболочки и повышение ее механической прочности. Оболочка содержит корпус 1 с приваренным к ней полым выпуклым ребром 2 плоского фланца 3 с резьбовыми отверсти ми . Крьпика 4 соединена с ребром 2 оболочки при помощи крепежных элементов 5. При этом оси резьбовых отверстий в поперечном сечении совпадают со стенкой обечайки, что позвол ет исключить изгибающий момент, воздействующий на фланец оболочки во врем испытаний, иммитирующих давление взрыва. В результате увеличиваетс механическа прочность оболочки и, следовательно, снижаетс ее материалоемкость. 3 з.п. ф-лы, 3 ил. (ЛThe invention relates to electrical equipment:; - engineering, in particular to explosion-proof electrical equipment enclosures, intended for use in explosive production facilities. The purpose of the invention is to reduce the material intensity of the shell and increase its mechanical strength. The shell includes a housing 1 with a hollow convex rib 2 of a flat flange 3 welded to it, with threaded holes. Krypka 4 is connected to the edge 2 of the shell using fasteners 5. The axis of the threaded holes in the cross section coincide with the wall of the shell, which eliminates the bending moment acting on the flange of the shell during the tests that simulate the pressure of the explosion. As a result, the mechanical strength of the shell increases and, consequently, its material consumption decreases. 3 hp f-ly, 3 ill. (L
