And the vacuum interrupter using the fixing means fixed mask cylinder and porcelain shell.
Background technique
Vacuum interrupter is the core component of vacuum switch, should carry, closes, cut-off running current and short circuit
Fault current need to also keep good insulating capacity in gate-dividing state.The shielding barrel part of vacuum interrupter is used to absorb electricity
The electric arc product for flowing interrupting process, avoids porcelain shell inner wall from being caused insulating capacity to decline by metal vapor deposition.
Common shielding cylinder fixed form has intermediate sealing-in formula, platform rotary extrusion type spinning in exposed, porcelain shell, platform welded type in porcelain shell
Deng.Intermediate sealing-in formula fixed form passes through the side being brazed between porcelain shell and intermediate sealing ring, between shielding cylinder and intermediate sealing ring
Formula realizes that shielding cylinder is fixed, and has the advantages that fixation is reliable, and the processing is simple, inner wall does not need processing step for porcelain shell, but
Which needs two section porcelain shells, had not only increased twice weld seam and had increased gas leakage probability, but also position is sealed in presence to porcelain shell appearance
The possibility of face electric discharge.Exposed fixed form is equivalent to the differentiation of intermediate sealing-in formula, which eliminates intermediate sealing ring,
Keep shielding cylinder exposed, shielding cylinder both ends are directly brazed with porcelain shell end face, and which increases in the not increased situation of porcelain shell diameter
Shielding cylinder diameter to be suitable for being relatively large in diameter the arrangement of the biggish electrode of connecting-disconnecting function, but can significantly be increased using which
Add arc-chutes height, is unfavorable for product miniaturization.Platform rotary extrusion type spinning fixed form uses a section porcelain shell in porcelain shell, has on porcelain shell inner wall
Fixed mask cylinder step hangs fixation after making shielding cylinder spinning port flange by a port of mechanical spinning shielding cylinder
In in porcelain shell on platform, which does not have the middle envelope position electric discharge problem of intermediate sealing-in formula, and has that cost is relatively low, easily to operate
Advantage, but have the defects that easily to loosen skew after high temperature after shielding logical fix.Platform welded type fixed form is equally adopted in porcelain shell
Have a section porcelain shell of fixed mask cylinder step with inner wall, but the step needs to process metalization layer, in order to shielding cylinder pricker
Weldering, the fixed form operation are easy, shielding cylinder fixation, but due in porcelain shell step need to process metalization layer, increase
Porcelain shell manufacturing cost.
Summary of the invention
The purpose of the present invention is to provide the fixing means of a kind of shielding cylinder and porcelain shell, use interior step without processing gold

The fixation work of shell.
The features of the present invention also characterized in that
The sticking part is connected with expansion mouth far from one end of mounting part.
Before the liner transition rings are mounted on the step of the porcelain shell and are welded with shielding cylinder, further comprise the steps of:
The expansion mouth of the liner transition rings is wrapped at the step lower end inclined-plane of the porcelain shell using spinning mode.
The shielding cylinder is fixed with liner transition rings using brazing mode.
Another technical solution of the present invention is: a kind of vacuum interrupter, the liner including porcelain shell, metal material
Transition rings and shielding cylinder；
The inner wall of the porcelain shell has step, and the step lower end is inclined-plane；
The liner transition rings include the mounting part being sequentially connected, sticking part and expansion mouth, and the mounting part is mounted on
The side wall of the upper surface of the step, the sticking part and the step fits, the expansion mouth and the step lower end
Inclined-plane fits；
The shielding cylinder is mutually fixed with the liner transition rings by welding manner.
The beneficial effects of the present invention are: the fixing means of a kind of shielding cylinder of the invention and porcelain shell, using thin-walled liner mistake
Ring scheme is crossed, platform in porcelain shell is made not need processing metalization layer, reduces porcelain shell manufacturing cost, the intermediate position soldering of shielding cylinder
It is fixed in liner transition rings, so that shielding cylinder fixation, is not easy deflection, it is good to positivity.The fixing means has taken into account porcelain
Platform rotary extrusion type spinning in shell, in porcelain shell the advantages of two kinds of shielding cylinder fixed forms of platform welded type, existing shielding cylinder fixation is reliable, solid
Surely the technical advantage to work well, and the cost advantage low with porcelain shell processing cost.Vacuum interrupter of the invention, shielding
Cylinder and porcelain shell use above-mentioned fixed form, so that shielding cylinder is fixed, to improve its performance.
