Portion, static side part pass sequentially through quiet cover board I and quiet cover board II and pass through exterior vacuum chamber and inner vacuum chamber, static side part respectively with quiet cover board I
With II vacuum welding of quiet cover board.
In a kind of vacuum extinction cell structure with dual-vacuum chamber above-mentioned, the moved end part is located at exterior vacuum chamber upper end
Portion, moved end part centre position pass through bellows II and dynamic cover board by bellows I and I vacuum welding of dynamic cover board, moved end part top
II vacuum welding.
In a kind of vacuum extinction cell structure with dual-vacuum chamber above-mentioned, the exterior vacuum chamber and inner vacuum chamber are close
The vacuum interior space of envelope.
Compared with prior art, using ceramic insulation nesting type structure, design, there are two the arc extinguishings of vacuum chamber for manufacture tool
The arc-chutes with 2 vacuum chambers are designed by increasing a vacuum chamber in room；Static side part and quiet cover board I, II vacuum welding,
Moved end part is welded by bellows I and dynamic cover board I, and quiet cover board II, dynamic cover board I are carried out vacuum welding with ceramic insulation shell I,
To constitute the vacuum interior space of sealing, i.e. inner vacuum chamber；The exterior vacuum chamber is after the completion of inner vacuum chamber welds, by moved end
Component II is welded by bellows II and dynamic cover board II, and quiet cover board I, dynamic cover board II are carried out vacuum welding with ceramic insulation shell II
It connects, to constitute the vacuum interior space of sealing, i.e. exterior vacuum chamber.
By using the structure of ceramic insulation housing nests ceramic insulation shell, solves any one inside and outside vacuum chamber and go out
When existing gas leakage or when low " vacuum " problem, caused connecting-disconnecting function to vacuum interrupter, service life influence the problem of,
The present invention has been effectively ensured when there is problem above, still can keep the indoor vacuum degree of arc extinguishing there are one vacuum chamber, make vacuum
Arc-chutes remain to work normally, and improve the reliability of arc-chutes；It is controlled according to conventional production, a vacuum chamber leak rate exists
1, two nested type vacuum chamber leak rates are 1 × 1=1ppm；Reach product reliability performance.
In conclusion present invention tool there are two the arc-chutes of vacuum chamber, can reduce when leaking air or low vacuum problem
Probability improves the reliability of product, avoids the connecting-disconnecting function of vacuum interrupter impacted, and making for vacuum interrupter greatly improved
Use the service life.
