Abstract
Moving and static cover plates used for a vacuum arc-extinguishing chamber comprise a moving cover plate (1) and a static cover plate (2). The moving cover plate (1) and the static cover plate (2) are provided with annular solder grooves respectively. The moving cover plate (1) and the static cover plate (2) are welded on two ends of the vacuum arc-extinguishing chamber (3) through the solder. And the two ends of the vacuum arc-extinguishing chamber (3) are located in the annular solder grooves of the moving cover plate (1) and the static cover plate (2) respectively. The moving and static cover plates of the utility model have the following advantages that the current moving and static cover plates are improved; the two ends of the vacuum arc-extinguishing chamber (3) are located in the annular solder grooves of the moving cover plate (1) and the static cover plate (2) so that an air leakage phenomenon is not easy to generate and security of usage is guaranteed.
Description
Technical field
The utility model relates to the vacuum interrupter field, is specifically related to a kind of sound cover plate for vacuum interrupter.
Background technology
At present, sound cover plate on traditional vacuum interrupter all adopts respectively stainless steel to make, all first solder sheet to be placed on vacuum interrupter two ends during welding, then the sound cover plate is welded on respectively the two ends of vacuum interrupter, this kind welding manner is not only wasted material, and be difficult for reaching quality standards in welding process, in use procedure, easy gas leakage will cause heavy losses.
The utility model content
The purpose of this utility model is exactly all to adopt respectively stainless steel to make for the sound cover plate at present traditional vacuum interrupter, all first solder sheet to be placed on vacuum interrupter two ends during welding, then the sound cover plate is welded on respectively the two ends of vacuum interrupter, this kind welding manner is not only wasted material, and be difficult for reaching quality standards in welding process, in use procedure, easy gas leakage will cause the deficiency of heavy losses, and a kind of sound cover plate for vacuum interrupter is provided.
The utility model comprises moving cover plate and quiet cover plate, have the annular welds hopper on moving cover plate and quiet cover plate, moving cover plate and quiet cover plate are welded on vacuum interrupter two ends by scolder respectively, and vacuum interrupter two ends lay respectively in the annular welds hopper of moving cover plate and quiet cover plate.
The material of moving cover plate and quiet cover plate is respectively electrical pure iron.
The utility model advantage is: existing sound cover plate is improved, vacuum interrupter two ends are placed in respectively in the annular welds hopper of dynamic and static cover plate, this kind mode is difficult for the phenomenon that leaks air, and guarantees the fail safe of using.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the covering plate structure schematic diagram.
Embodiment
As shown in Figure 1, 2, the utility model comprises moving cover plate 1 and quiet cover plate 2, it is characterized in that having the annular welds hopper on moving cover plate 1 and quiet cover plate 2, moving cover plate 1 and quiet cover plate 2 are welded on vacuum interrupter 3 two ends by scolder respectively, and vacuum interrupter 3 two ends lay respectively in the annular welds hopper of moving cover plate 1 and quiet cover plate 2.
The material of moving cover plate 1 and quiet cover plate 2 is respectively electrical pure iron.
Processing mode: first will move by lathe the annular welds hopper that cover plate 1 and quiet cover plate 2 cars go out 0.8-1mm thickness, then scolder is placed in respectively in the annular welds hopper of moving cover plate 1 and quiet cover plate 2, then will move the two ends that cover plate 1 and quiet cover plate 2 are welded on respectively vacuum interrupter 3, and vacuum interrupter 3 two ends lay respectively in the annular welds hopper of moving cover plate 1 and quiet cover plate 2.
