Abstract
A kind of flexible connection structure, for the thermoplastic plastic pole of 2000A and above current class, in pole, lower installation portion moving conductive rod of vacuum arc extinguish chamber is connected with lower wire outlet seat and adopts novel flexible connection structure.Comprise housing and be embedded in the upper wire outlet seat in housing, vacuum interrupter, conductive clip, is flexible coupling, contiguous block, lower wire outlet seat composition.On pole, the quiet end of installation portion vacuum interrupter is electrically connected with upper wire outlet seat, is bolted.Under pole, installation portion movable end of vacuum arc extinguishing chamber is by conductive clip, is flexible coupling and contiguous block is electrically connected by bolt or welding manner with lower wire outlet seat.Under the utility model pole, installation portion adopts unique flexible connection structure to connect, and while the original technical performance of guarantee, lower installation portion volume of part is less, easily processes.Leading to use bolt to install.Thus reduce processing cost, install more for convenience, and the void volume added in pole chamber thus there is better heat dispersion.
Description
Technical field
The utility model relates to field of electrical equipment, is specifically related to a kind of flexible connection structure of thermoplastic plastic pole-for the thermoplastic plastic pole of 2000A and above current class.
Background technology
In middle/high-voltage electrical appliance field, vacuum circuit-breaker is the electric equipment for control and protection electric power system. and the pole comprising vacuum interrupter is the core component of vacuum circuit-breaker.
Simultaneously pole is embedded in solid insulating material with relative conductive pieces by vacuum interrupter to form pole. make the parts that whole pole becomes as a whole. and the thermoplastic plastic pole of current existing 2000A and above current class, mainly comprise insulation crust (1), import the upper wire outlet seat of electric current, vacuum interrupter (2), the lower wire outlet seat (5) of derived current. the fixed contact of vacuum interrupter (2) is electrically connected with upper wire outlet seat, the moving conductive rod of vacuum interrupter (2) is electrically connected (accompanying drawing 1) by slide block (4) and spring touch finger (3) with lower wire outlet seat (5). and this mode can ensure good electric conductivity and insulation effect. but lower wire outlet seat material is T2 copper, volume is larger, cause its part processing cost higher, install comparatively loaded down with trivial details, and pole internal volume is too little and cause heat dispersion poor.
For existing 2000A and above current class thermoplastic plastic pole existing for problem, provide a kind of great-current fixed sealed pole of newtype to have great importance.
Utility model content
The utility model discloses a kind of flexible connection structure of thermoplastic plastic pole, for the thermoplastic plastic pole of 2000A and above current class. pole mechanism comprises housing and is embedded in the upper wire outlet seat in housing, vacuum interrupter, conductive clip, be flexible coupling, contiguous block, lower wire outlet seat composition. on pole, the quiet end of installation portion vacuum interrupter is electrically connected with upper wire outlet seat, under pole, installation portion conductive clip and contiguous block are by being flexible coupling with bolt or being welded and fixed, moving conductive rod of vacuum arc extinguish chamber is electrically connected with conductive clip, contiguous block is electrically connected by bolt with lower wire outlet seat.This mounting means
High to solve part processing cost in prior art, install too loaded down with trivial details, the problems such as heat dispersion difference.
Accompanying drawing explanation
Fig. 1 is the great-current fixed sealed pole sectional structure schematic diagram of prior art.
Fig. 2 ~ 3 are pole broken section structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As Figure 2-3, the thermoplastic plastic pole of 2000A and above current class.The upper wire outlet seat comprising housing (1) and be embedded in housing (1), vacuum interrupter (2), conductive clip (3), be flexible coupling (5), contiguous block (6), lower wire outlet seat (4) composition.The upper installation portion of pole, the quiet end of vacuum interrupter (2) is electrically connected with upper wire outlet seat, fixes with bolt.Installation portion under pole, conductive clip (3) and contiguous block (6) are fixed with bolt or welding manner by be flexible coupling (5), vacuum interrupter (2) moving conductive rod is electrically connected with conductive clip (3), and contiguous block (6) is electrically connected by bolt with lower wire outlet seat (4).
The utility model is used for the flexible connection structure of the thermoplastic plastic pole of 2000A and above current class.Lower installation portion adopts unique flexible connection structure to connect.Compared with existing great-current fixed sealed pole technology, while the technical performances such as guarantee material, lower installation portion volume of part is less, easy processing. logical bolt or the welding manner of can using is installed, thus reduce the processing cost of part, install also more for convenience, and add the void volume in pole chamber, thus have better heat dispersion.
Claims (1)
1. the flexible connection structure of a thermoplastic plastic pole, for the thermoplastic plastic pole of 2000A and above current class, it is characterized in that described great-current fixed sealing pole mechanism comprises housing and is embedded in the upper wire outlet seat in housing, vacuum interrupter, conductive clip, be flexible coupling, contiguous block, lower wire outlet seat composition. on pole, the quiet end of installation portion vacuum interrupter is electrically connected with upper wire outlet seat, under pole, installation portion conductive clip and contiguous block are by being flexible coupling with bolt or being welded and fixed, moving conductive rod of vacuum arc extinguish chamber is electrically connected with conductive clip, contiguous block is electrically connected by bolt with lower wire outlet seat.
