line protection switch with an arrangement of con- tacts forming a loop blowing

摘要

1. protection switch line with a contact arrangement which forms a blowing loop, which is constituted by a fixed contact and a moving and a loop additional blowing that acts on the arc, wherein the blowing loop additional is in the moving contact and can move along with it. 2. Switch according to claim 1, wherein the additional blowing loop is retained by the profile, preferably a profile in the form of "U" of the movable contact. 3.Interruptor, according to previous claims, characterized in that the additional blowing loop is formed by a connection cord anyway necessary for the movable contact. 4. Switch according to the preceding claims, characterized in that in the case of a contact arrangement with double interruption, the contact bridge consists of two bridge parts which cooperate each with a fixed contact and which are joined together by additional blowing loop located behind them. 5. Switch according to the preceding claim, characterized in that additional blowing loops remain mechanically coupled to the two bridge. 6.Interruptor, according to previous claims, characterized in that the action of additional blowing loop or loops additional blowing is reinforced by other blowing loop located behind the fixed contact. 7.Interruptor line protector with a contact arrangement forming a blowing loop.
