Embodiment Construction

[0036] In the attached drawings, a vacuum interrupter A can be seen, intended for use in low or medium voltage electrical protection devices, such as circuit breakers or electrical switches. This interrupter is usually arranged in a shunt circuit installed in parallel with the so-called main circuit comprising the main contacts of the above-mentioned device. These arcing contacts are intended to take the short-circuit current when the interrupter is incorporated in a circuit breaker, and to ensure breaking current when the interrupter is incorporated in a switch.

[0037] Known per se, this interrupter A comprises an elongated tube under vacuum comprising a cylindrical sheath 1 closed by two end walls 2 , 3 . The above two arcing contacts 4, 5 consist of a first arcing contact 4, called the stationary contact, fixed to one of the two end walls 2, while the other arcing contact 5, called the moving contact, is mounted on the rod 6 mounted to slide through the other 3 of the tw...

Abstract

The present invention relates to a vacuum interrupter comprising an elongated tube in a vacuum comprising a cylindrical sheath surrounded by two end walls (2,3), which are respectively referred to as first and second end walls (1) in which two arc contacts (4, 5) are accommodated, the stationary contact (4) of one of said arc contacts being secured to a first end wall (2) of one of said end walls, the other (5) movable contact is mounted at the end of the rod (6) which is mounted so that the second end wall of the other (3) through the end wall is at the end of the arc contact (4,5) The first so-called closed position of the opposite end of the interrupter A is slid in the axial direction between the open position of the arc contact and the opened position of the separate interrupter, and a compression spring (11) adapted to apply contact (5) in the closed position of said arc contact (4, 5).

Description

technical field [0001] The present invention relates to a vacuum interrupter comprising an elongated tube under vacuum, said tube comprising a cylindrical sheath enclosed by two end walls, referred to respectively as first and second end walls, containing two arcing contacts, the stationary contact of one of the arcing contacts is fixed to the first end wall of one of the above-mentioned end walls, and the other moving contact is mounted on the end of a rod mounted to pass through the above-mentioned end wall The second end wall of the other wall is axially between the first so-called closed position, in which the arcing contacts are end-to-end interrupters, and the open position, in which the arcing contacts are separated interrupters. An internal slide, and compression spring adapted to exert a contact pressure on the moving arcing contact in the closed position of said arcing contact. [0002] The invention also relates to a low or medium voltage electrical protection devi...
