Abstract
The utility model provides a movable rod of a vacuum tube in a vacuum circuit breaker, which comprises a rod-shaped part and a shielding pan, wherein the rod-shaped part and the shielding pan are an integrally formed structure. A vacuum tube provided with the movable rod, wherein the shielding pan and the rod-shaped part in the movable rod are in integrally formed structure. The movable rod in the vacuum tube of the vacuum circuit breaker is an integrally formed structure, thereby improving the electrical conductivity and the precision degree of the vacuum tube, and being capable of reducing the production cost of the vacuum circuit breaker simultaneously.
Description
Technical field
The utility model relates to copper accessory that a kind of vacuum circuit-breaker uses and the vacuum tube that is provided with this copper accessory.The moving bar of vacuum tube and be provided with the vacuum tube of this moving bar in specifically a kind of vacuum circuit-breaker.
Background technology
Vacuum circuit-breaker is the visual plant in the power network, and it uses vacuum extinction technology, has that breaking capacity is strong, a not oxidation of contact, electric arc does not expose, volume is little, in light weight, safe and reliable advantage, uses comparatively universal in power distribution network.Comprise vacuum interrupter in the vacuum circuit-breaker, vacuum tube is housed in the arc control device, vacuum tube generally comprises the quiet cover plate and moving bar, inner dynamic/static contact and the parts such as bellows that are connected with described moving bar that is arranged on two ends.Wherein, as depicted in figs. 1 and 2, moving bar will divide body formed rod-like members 10 and blanking disc 20 to weld together processing by filamentary silver to obtain, form the projection 30 that is suitable for installing on the described blanking disc 20.There is following defective in the moving bar of prior art: at first, if welding is improper between blanking disc and the rod-like members, main product leaks gas easily in the welding position, will directly have influence on the breaking capacity and the useful life of vacuum circuit-breaker; Have again,, make that the assembling of vacuum tube is loaded down with trivial details, complex process, cost height because blanking disc and rod-like members split are provided with.
Summary of the invention
For this reason, technical problem to be solved in the utility model is need carry out assembling, the welding of blanking disc and rod-like members when existing moving bar is made, and complicated, the easy gas leakage of technology proposes the moving bar in a kind of integrated vacuum tube.
And then, a kind of vacuum tube that is provided with this integrated moving bar is proposed.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: the moving bar of vacuum tube in a kind of vacuum circuit-breaker comprises rod-like members and blanking disc, the structure that described rod-like members and described blanking disc are formed in one.
In technique scheme, described blanking disc is looped around around the described rod-like members and is provided with the projection that is suitable for installing.
In technique scheme, described rod-like members main body is a cylindrical shape.
A kind of vacuum tube that is provided with described moving bar, described moving bar comprises rod-like members and blanking disc, the structure that described rod-like members and described blanking disc are formed in one.
In technique scheme, described blanking disc is looped around around the described rod-like members and is provided with the projection that is suitable for installing.
In technique scheme, described rod-like members main body is a cylindrical shape.
Technique scheme of the present utility model has the following advantages compared to existing technology: at first, the structure that moving bar is formed in one, because rod-like members and blanking disc move when work simultaneously, integrative-structure has also strengthened the conductivity and the precision of vacuum tube, has improved the seal and the mar proof of vacuum tube.Have, the one-time formed structure of rod-like members has been simplified production technology again, makes the vacuum tube assembling simple, has prolonged the useful life of main product vacuum circuit-breaker simultaneously, can also reduce its production cost simultaneously.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, according to specific embodiment of the utility model also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is the cross section structure schematic diagram of rod-like members part in the moving bar of prior art;
Fig. 2 is the cross section structure schematic diagram of blanking disc part in the moving bar of prior art;
Fig. 3 is the cross section structure schematic diagram of a kind of embodiment of moving bar of the present utility model;
Reference numeral is expressed as among the figure: 10-rod-like members, 20-blanking disc, 30-projection, 1-rod-like members, 2-blanking disc, 3-projection.
Embodiment
The moving bar of vacuum tube in a kind of vacuum circuit-breaker comprises rod-like members 1 and blanking disc 2, the structure that described rod-like members 1 and described blanking disc 2 are formed in one.Described blanking disc 2 is looped around around the described rod-like members 1 and is provided with the projection 3 that is suitable for installing.Described rod-like members 1 main body is a cylindrical shape.
Moving bar of the present utility model, the structure that it is formed in one, and with the structure of the moving bar of existing split assembling, promptly rod-like members, the blanking disc structure after through plug-in mounting, welding is identical.Owing to saved the step of plug-in mounting, welding, make should moving bar structure firm and assembling is simple.Simultaneously, because rod-like members and blanking disc move when work simultaneously, integrative-structure has also strengthened the conductivity and the precision of vacuum tube, has improved its seal and mar proof.Can also reduce its production cost in addition, be suitable for large-scale the popularization and produce.
Certainly, because structural similarity, the operation principle of vacuum contactor and vacuum circuit-breaker are identical, moving bar of the present utility model can be applied in the vacuum tube in the vacuum contactor equally.
Obviously, the foregoing description only is for example clearly is described, and is not the qualification to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all execution modes.And conspicuous variation of being extended out thus or change still are in the protection range of the invention.
