TWO-PIECE SNAP-ON MOVABLE CONTACT THAT REDUCES CONTACT STICKING IN EPOXY-BODIED SF6 GAS-FILLED LOAD DISCONNECTORS USED IN AIR-INSULATED SWITCHING DEVICES.

Abstract

The invention is a movable contact (10) that reduces contact adhesion in epoxy insulated load disconnectors. It is related to the movable contact (10), which has the same geometric form and is opposite to each other. The first contact piece (20) and the second contact are positioned in an oriented manner. part (30), through the connecting sections (40) in the middle parts rigid placement and using the connecting plate (50) and connecting elements (60) It is formed by combining contact parts in this way. The contact parts are located at the same end. The protrusions (70) are positioned to interlock with each other and form two separate contacts (90) with a fixed contact. It provides contact at the point. Two movable contacts (10) are between the fixed contact (90) They are positioned opposite each other so that there is a suitable contact gap (80) for the inlet. When the fixed contact (90) enters the contact range, a total of at least four contact points are formed. and pre-arc induced contact adhesion is reduced.
