Abstract
The utility model relates to the technical field of electronic accessories, and especially relates to a high-performance vacuum switch tube installed at a vacuum electromagnetic starter. The high-performance vacuum switch tube has a vacuum sealed container formed by a high alumina ceramic circular ring; wherein a corrugated tube is welded to one end of the sealed container, the other end of the corrugated tube is provided with a moving contact; the other end of the sealed container is provided with a metal shielding cover, the metal shielding cover is covered by a circular plate, a static contact is welded to the circular plate, and an outer wall of one end of the static contact is provided with a threaded section. The high-performance vacuum switch tube of the utility model has the advantages of simple structure, reasonable design, small volume, high voltage resistance, good breaking capacity, long service life, no need for contact maintenance, no exposure for arcs, allowable frequent operation, etc.; in addition, the high-performance vacuum switch tube is reliable in installation, thus the high-performance vacuum switch tube is suitable for a heavy-current explosion-proof switch.
Description
Technical field
The utility model relates to the electronic accessories technical field, especially a kind of high-performance vacuum switch tube that is installed on vacuum electromagnetic starter.
Background technology
Vacuum switch tube cut-offs device as circuit, is widely used in flame-proof switch.At present, be used for the vacuum switch tube of flame-proof switch such as vacuum magnetic starter, install complicatedly, it is unreliable to install, and when large electric current by the time generate heat easily, so be difficult to be applicable to large electric current flame-proof switch.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, provide a kind of simple in structure, install reliably, be applicable to the vacuum switch tube of large electric current flame-proof switch.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of high-performance vacuum switch tube, have the vacuum-tight container that the high alumina ceramic annulus consists of, and described airtight container one end is welded with bellows, and the bellows other end is provided with moving contact; The described airtight container other end arranges metallic shield, and metallic shield is by the plectane capping, and described plectane is welded with fixed contact, and the first end outer wall of stationary contact car has thread segment.
Further, described high-performance vacuum switch length of tube is 90-100mm, and high-performance vacuum switch tube width is 45-60mm.
The beneficial effects of the utility model are: the utility model is simple in structure, and is reasonable in design, and volume is little, high pressure resistant, breaking capacity is strong, long service life, and contact needn't keep in repair, and electric arc does not expose, allow the advantages such as frequent operation, install reliably, be applicable to large electric current flame-proof switch.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. moving contacts among the figure, 2. bellows, 3. airtight container, 4. metallic shield, 5. plectane, 6. fixed contact.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
