Abstract
The utility model relates to a heavy current is from dispelling heat vacuum switch tube. It is the heavy current vacuum switch tube who has automatic heat dispersion specifically to say. It includes insulating casing, and all there is the pole hole at the insulating casing both ends. Wherein, pole is downthehole to have conducting rod and the two to be sliding fit, and another pole is downthehole to have quiet conducting rod and the two to be the fixed coordination. The inner end welding of quiet conducting rod has the static contact, and the inner end welding of moving the conducting rod has the moving contact, is the mutual disposition between moving contact and static contact. Neighbouring moving contact move the conducting rod inner end on have the ring of keeping off, be in that section in the insulating casing move the conducting rod on the cover have the spring, the spring both ends offset with the one end of keeping off ring sum insulating casing respectively. Its characteristics are it has the fin to link in the overhanging section of quiet conducting rod. This kind of heavy current vacuum switch tube, long service life, application range is wide.
Description
Technical field
The utility model relates to a kind of vacuum switch tube.Specifically, be the big current vacuum switch tube with automatic heat radiation performance.
Background technology
All know at electrical device manufacturing field, big current vacuum switch tube is commonly used in vacuum contactor, and big current vacuum switch tube is often operated in big current environment.Described big current vacuum switch tube comprises insulation crust, and all there is rod aperture at insulation crust two ends.Wherein, there is moving conductive rod in a rod aperture and in being slidably matched between the two, having static conductive rod in another rod aperture and in secure fit between the two; The inner end of static conductive rod is welded with fixed contact, and the inner end of moving conductive rod is welded with moving contact, in positioned opposite between moving contact and fixed contact.There is baffle ring the moving conductive rod inner end of contiguous moving contact, and being in cover on that section of moving conductive rod in insulation crust has spring, and both ends of the spring offsets with one end of baffle ring and insulation crust respectively.Overhanging section of static conductive rod is wherein polished rod and without any cooling measure, the area of dissipation of big current vacuum switch tube is made only to have insulation crust and dynamic and static conducting rod overhanging section, area of dissipation is less, after working long hours, body easily generates heat, and makes the useful life of big current vacuum switch tube shorter.Want the useful life extending big current vacuum switch tube, its rated operational current just can not be too large, so, again limit the scope of application of vacuum contactor.
Utility model content
Problem to be solved in the utility model is to provide a kind of big current from dispelling the heat vacuum switch tube.This big current vacuum switch tube, long service life, the scope of application is wide.
The problems referred to above to be solved in the utility model are realized by following technical scheme:
Big current of the present utility model comprises insulation crust from heat radiation vacuum switch tube, and all there is rod aperture at insulation crust two ends.Wherein, there is moving conductive rod in a rod aperture and in being slidably matched between the two, having static conductive rod in another rod aperture and in secure fit between the two.The inner end of static conductive rod is welded with fixed contact, and the inner end of moving conductive rod is welded with moving contact, in positioned opposite between moving contact and fixed contact.There is baffle ring the moving conductive rod inner end of contiguous moving contact, and being in cover on that section of moving conductive rod in insulation crust has spring, and both ends of the spring offsets with one end of baffle ring and insulation crust respectively.Be characterized in overhanging section of described static conductive rod is connected with fin.
As can be seen from the above scheme, owing to being connected with fin on overhanging section of static conductive rod, the area of dissipation of big current vacuum switch tube is added, good heat dissipation effect.Even if after working long hours, body also not easily generates heat, thus extends the useful life of big current vacuum switch tube.Again owing to being connected with fin on overhanging section of static conductive rod, add the area of dissipation of big current vacuum switch tube, good heat dissipation effect, big current vacuum switch tube rated operational current can be improved, thus expand the scope of application of vacuum contactor.
Accompanying drawing explanation
Fig. 1 is that big current of the present utility model is from heat radiation vacuum switch tube structural representation.
Embodiment
As shown in Figure 1, big current of the present utility model comprises insulation crust 5 from heat radiation vacuum switch tube, and described insulation crust 5 is cylindric, and its two ends are all connected with cover of meter hood 3, and cover of meter hood 3 is all processed with centre bore, make insulation crust 5 two ends all have rod aperture.Moving conductive rod 4 being installed and in being slidably matched between rod aperture and moving conductive rod 4 in one of them rod aperture, static conductive rod 8 being installed and in secure fit between rod aperture and static conductive rod 8 in another rod aperture.The inner end of static conductive rod 8 is welded with fixed contact 7, and the inner end of moving conductive rod 4 is welded with moving contact 6, in positioned opposite between moving contact 6 and fixed contact 7.Moving conductive rod 4 inner end of contiguous moving contact 6 is fixed with baffle ring 1, and being in cover on that section of moving conductive rod 4 in insulation crust 5 has spring 2, and spring 2 two ends offset with the cover of meter hood 3 of baffle ring 1 and insulation crust 5 one end respectively.For increasing heat radiation area, overhanging section of described static conductive rod 8 is connected with three fin 9.
For ease of the installation of fin 9, overhanging section of described static conductive rod 8 is processed with screw thread, be processed with screw at the center of described fin 9, three fin 9 all by the screwed on the screw at its center and overhanging section of static conductive rod 8 on overhanging section of static conductive rod 8.By increasing the area of dissipation of big current vacuum switch tube, improve radiating effect, extending the useful life of big current vacuum switch tube.And by increasing the area of dissipation of big current vacuum switch tube, improving radiating effect, big current vacuum switch tube rated operational current can be improved, making the scope of application of vacuum contactor unrestricted.
