Abstract
The utility model discloses a kind of 12KV and be with copper fairlead vacuum switch tube, relate to a kind of 12KV vacuum circuit-breaker vacuum switch tube.It comprises porcelain cylinder, moving conductive rod and static conductive rod is provided with at the two ends shaft core position of porcelain cylinder, static conductive rod is set with quiet end cap, quiet end cap is fixed on one end of porcelain cylinder, it is characterized in that: also comprise multiple spaced apart screw rod, the upper end of described moving conductive rod is set with copper fairlead and moved end lid successively, and moved end lid is fixed on one end of porcelain cylinder, described copper fairlead is provided with multiple screw arranged uniformly at intervals, and screw rod is threaded with copper fairlead by screw.The utility model structure is simple, easy to use, and vacuum switch tube can be connected and fixed by screw rod and vacuum circuit-breaker, thus prevents vacuum switch tube from occurring rocking when vacuum circuit-breaker folding, and then reaches the object improving vacuum switch tube useful life.
Description
Technical field
The utility model relates to a kind of 12KV vacuum circuit-breaker vacuum switch tube, and a kind of 12KV is with copper fairlead vacuum switch tube specifically.
Background technology
The fairlead of existing 12kv vacuum switch tube is nylon fairlead, and when assembling, the vacuum switch tube of band nylon fairlead directly loads vacuum circuit-breaker, do not have installation and positioning structure between vacuum switch tube and vacuum circuit-breaker.Existing vacuum circuit-breaker is in moving process, and rocking, easily causing contact dystopy easily appears in the body of vacuum switch tube, thus causes vacuum tube probability of damage bigger than normal, and then can reduce the useful life of vacuum switch tube, is therefore necessary to improve.
Summary of the invention
The purpose of this utility model is the weak point in order to overcome background technology, and provides a kind of 12KV to be with copper fairlead vacuum switch tube.
To achieve these goals, the technical solution of the utility model is: 12KV is with copper fairlead vacuum switch tube, comprise porcelain cylinder, moving conductive rod and static conductive rod is provided with at the two ends shaft core position of porcelain cylinder, static conductive rod is set with quiet end cap, quiet end cap is fixed on one end of porcelain cylinder, it is characterized in that: also comprise multiple spaced apart screw rod, the upper end of described moving conductive rod is set with copper fairlead and moved end lid successively, moved end lid is fixed on one end of porcelain cylinder, described copper fairlead is provided with multiple screw arranged uniformly at intervals, screw rod is threaded with copper fairlead by screw.
In technique scheme, the number of described screw and the number of screw rod are 3 ~ 5.
The utility model changes the nylon guide of existing vacuum switch tube into copper fairlead to cover, and on vacuum switch tube, install the screw rod be threaded with copper fairlead.The utility model structure is simple, easy to use, and vacuum switch tube can be connected and fixed by screw rod and vacuum circuit-breaker, thus prevents vacuum switch tube from occurring rocking when vacuum circuit-breaker folding, and then reaches the object improving vacuum switch tube useful life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the complete section structural representation of copper fairlead.
1-static conductive rod in figure, the quiet end cap of 2-, 3-copper fairlead, 4-porcelain cylinder, 5-moving conductive rod, 6-screw rod, 7-moved end is covered, 8-screw.
Embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not form to restriction of the present utility model, only for example.Make advantage of the present utility model clearly and easy understand by explanation simultaneously.
Accompanying drawings is known: 12KV is with copper fairlead vacuum switch tube, comprise porcelain cylinder 4, moving conductive rod 5 and static conductive rod 1 is provided with at the two ends shaft core position of porcelain cylinder 4, static conductive rod 1 is set with quiet end cap 2, quiet end cap 2 is fixed on one end of porcelain cylinder 4, it is characterized in that: also comprise multiple spaced apart screw rod 6, the upper end of described moving conductive rod 5 is set with copper fairlead 3 and moved end lid 7 successively, moved end lid 7 is fixed on one end of porcelain cylinder 4, described copper fairlead 3 is provided with multiple screw 8 arranged uniformly at intervals, and screw rod 6 is threaded with copper fairlead 3 by screw 8.The number of described screw 8 and the number of screw rod 6 are 3 ~ 5.
When the utility model is assembled on vacuum circuit-breaker, quiet end is fixed by static conductive rod 1 screw, moved end is fixed by copper fairlead and screw rod, therefore in moving conductive rod motion process, the vacuum switch tube be arranged on vacuum circuit-breaker not easily rocks, thus enhance the security performance of vacuum circuit-breaker, improve the useful life of vacuum switch tube.
Other unaccounted part all belongs to prior art.
