Abstract

The invention discloses an arc extinguishing chamber device of a vacuum circuit breaker. The device comprises a vacuum chamber, one side of the vacuum chamber is provided with a static contact througha static conducting rod, and the other side of the vacuum chamber is provided with a moving contact through a moving conducting rod; the vacuum chamber comprises an inner vacuum sleeve wrapping the static contact and the moving contact. A first sealing assembly is arranged between the inner vacuum sleeve and the movable conducting rod; an outer vacuum sleeve wraps the inner vacuum sleeve; a second sealing assembly is arranged between the outer vacuum sleeve and the movable conducting rod, and the sealing effect of the vacuum circuit breaker is effectively improved through the inner vacuum sleeve and the outer vacuum sleeve which are arranged in a sleeved mode and the first sealing assembly and the second sealing assembly which are arranged between the inner vacuum sleeve and the movable conducting rod and between the outer vacuum sleeve and the movable conducting rod respectively.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vacuum circuit breakers, and in particular to an arc extinguishing chamber device of a vacuum circuit breaker. Background technique [0002] The vacuum interrupter is the core component of the medium and high voltage power switch. It is mainly installed in the high voltage vacuum circuit breaker. Through the excellent insulation of the vacuum inside the tube, the medium and high voltage circuit can quickly extinguish the arc and suppress the current after the power supply is cut off, so as to stabilize the circuit. To avoid accidents and accidents, the inside of the airtight insulating shell of the vacuum interrupter plays an insulating role for the vacuum environment. [0003] In the vacuum interrupter of the prior art, the bellows is an indispensable component, which can not only ensure the sealing of the interrupter, but also realize the relative movement of the moving and static ...
