Abstract
The invention discloses a layered interleaved conductive structure for the movable end of a solid-sealed polar pole for a circuit breaker, comprising a lower outlet wire, the movable end of the solid-sealed polar pole movable end and a conductive-clip soft connecting part, wherein the conductive-clip soft connecting part is in a double-layer soft connecting structure, and the lower outlet wire is in a double-layer lap joint structure. Because the conductive-clip soft connecting part is in the up-down double-layer soft connecting structure and the lower outlet wire is in the double-layer lap joint structure, the number of the soft connectors is doubled, the sectional area of each soft connector in the space with the same diameter is doubled, the current carrying capacity is improved greatly, and 12 soft connectors can be arranged in the limited space. The layered interleaved conductive structure is compact in structure and small in appearance, meets the requirement for the rated current of over 3,150A under the condition of not enlarging the size of the appearance of the solid-sealed polar pole, is convenient to assemble and has high efficiency.
Description
Technical field
The present invention relates to a kind of HVAC vacuum circuit breaker, relate in particular to the staggered conductive structure of a kind of circuit breaker pole moved end layering.
Background technology
In the vacuum circuit-breaker field, the pole type circuit breaker is a fast-developing in recent years main flow direction.Especially in the 12kV electric pressure, solid sealing type vacuum circuit breaker has occupied the very large market advantage.Usually the structure of pole is made of the quiet link joint parts that bring out line, vacuum interrupter, moved end outlet and moved end outlet and movable end of arc extinguishing chamber.Wherein quiet to bring out line, vacuum interrupter, moved end outlet etc. all similar, and the link joint parts of moved end outlet and movable end of arc extinguishing chamber then become the core component parts of pole.The link joint parts of general moved end outlet and movable end of arc extinguishing chamber are divided into two kinds of forms: connecting structure and flexible connection structure namely slide.The slip connecting structure is higher to the manufacture process requirement of pole, and percent defective is also relatively high.And flexible connection structure is lower to manufacture process requirement, rate of finished products is very high simultaneously.But the pole of flexible connection structure design is realized comparatively difficulty, the design outline of general pole and the pole that volume all is greater than the slip connecting structure when rated current 3150A is above.
Patent " a kind of flexible connection structure of indoor high-voltage vacuum breaker solid sealed pole " (patent No. ZL200620031074.2, notification number CN2935450, day for announcing 207.08.15) the novel flexible connection structure that moving conductive rod is connected with lower conductive seat in the great-current fixed sealing pole vacuum breaker pole in a kind of electrical power distribution system is disclosed, it comprises several thick copper strips, lower copper billet and upper copper billet, thick copper strips is formed by stacking by the soft tire thin copper belt of several strips, and lower copper billet is the regular polygon slab construction.Although this patent is the annular syndeton that is flexible coupling, but it is flexible coupling and is single layer structure, copper billet is thin-slab structure on it, and explanation only need increase quantity and the thickness of copper strips along with the increase of electric current, and when electric current during greater than 3150A, this structure be difficult to realize that reason is that integrally-built profile diameter can not infinitely strengthen, and will guarantee simultaneously the kinematic dexterity that is flexible coupling.
Summary of the invention
The object of the present invention is to provide a kind of compact conformation, profile small and exquisite, it is convenient to assemble, the staggered conductive structure of a kind of circuit breaker pole moved end layering that efficient is high.
For achieving the above object, the technical scheme taked of the present invention is:
A kind of circuit breaker pole moved end layering conductive structure that interlocks, comprise the lower outlet that admittedly is encapsulated in the insulating cylinder, pole moved end and the conductive clip parts that are flexible coupling, the described conductive clip parts that are flexible coupling are double-deck flexible connection structure, and described lower outlet is double-deck bridging arrangement.
The described conductive clip parts that are flexible coupling comprise and being flexible coupling, described minute up and down two-layer being arranged on the conductive clip that be flexible coupling, and every layer is respectively arranged with six and is flexible coupling, and the angle between being flexible coupling with two on layer is described is 60 degree; Up and down two-layer described be flexible coupling between for shifting to install, the angle of dislocation is 30 degree.
Described lower outlet is double-deck bridging arrangement, and every layer evenly arranges six overlap joint planes.
Adopt circuit breaker pole provided by the invention moved end conductive clip flexible connection structure, be the Dual-layer flexible connection structure, lower outlet is double-deck bridging arrangement, this is equivalent to make the number that is flexible coupling to increase by one times, make the sectional area that is flexible coupling increase one times in the space of same diameter, current capacity also improves thereupon greatly.Realized 12 layouts that are flexible coupling in limited space, compact conformation, profile are small and exquisite, have realized the requirement more than the rated current 3150A in the situation that the pole profile does not increase, and assemble conveniently, and efficient is high.
