safety switch, in particular einsäulen - scherentrennschalter

摘要

shown and described is a safety switch, which is a einsu00e4ulen - scherentrennschalter with a prime contact (3) and (4), a hilfskontaktsystemalthough the prime contact (3) of the bus bars (5) mapped first kontaktstu00fcck (6) and a trennschere (2) to 255 (7) and the second kontaktstu00fcck hilfskontaktsystem (4) in the first kontaktstu00fcck (6) of the hauptkontaktes (3) assigned hilfskontaktstu00fccke (8) projects.the hilfskontaktstu00fccke (8) are trained and the corresponding hilfskontaktsystem (4) total opens after the prime contact.a constructively simple design of the trennschalters (1) and a safe switch under all conditions without the risk of u00fcberspringens of demolition arcs on the prime contact (3) is presented in the safety switch (1) is ensured bythat the hilfskontaktsystem (4) an electrically between the first kontaktstu00fcck (6) of the hauptkontaktes (3) and the hilfskontaktstu00fcck (8) arranged trennkontakt (10) with two kontaktbu00fcgeln (11, 12) is that the first kontaktbu00fcgel (11) of the first kontaktstu00fcck (6) and the second contact tbu00fcgel (12) of the hilfskontaktstu00fcck (8) is attached.that the second kontaktstu00fcck (7) directly on the hilfskontaktstu00fcck (8) to the plant and that after the opening of the hauptkontaktes (3) first of all, the trennkontakt (10) open, and then only the second kontaktstu00fcck (7) of hilfskontaktstu00fcck (8) answers. this is the whole hilfskontaktsystem (4) practically only the first......
