Abstract
The utility model relates to a shunt device for a moving conductive rod of a vacuum arc extinguish chamber, which has the following technical key points: a copper conductive clamp is arranged at the setting position of the moving conductive rod of the vacuum arc extinguish chamber, one end of a copper conductive band is fixedly connected with the copper conductive clamp, the other end of the copper conductive band is fixedly connected with the lower end of the conductive rod and the middle part of the copper conductive band is fixedly connected with a lower touching arm through screw bolts. The shunt device has simple structure and solves the problem that the flexible connection of the moving conductive rod and the lower touching arm is easy to generate heat, thus decreasing energy consumption and prolonging the service life of a vacuum circuit breaker.
Description
Technical field
The utility model relates to a kind of high voltage electric power equip ment accessory, particularly relates to a kind of vacuum interrupter moving conductive rod part flow arrangement.
Background technology
AC high voltage vacuum breaker is widely used in the 12kV-40.5kV switch cubicle.Wherein vacuum interrupter, go up contact arm, down contact arm, be flexible coupling and insulated tension pole etc. is the vitals of vacuum circuit-breaker current-carrying part.The quiet end of vacuum interrupter connects into an overall structure by bolt and last contact arm rear end, and the conducting rod of vacuum interrupter moved end is connected with following contact arm by being flexible coupling.The mode that is flexible coupling at present has two kinds, and the first is established conductive clip on above-mentioned conducting rod, and copper conductive strips one end is connected with conductive clip, the other end is connected with following contact arm, it two is that copper conductive strips one end directly is connected with the conducting rod lower end, and the other end is connected with following contact arm, constitutes the galvanic circle.But because dual mode is all very big by the current density of copper conductive strips, therefore easily heating, off-energy, and fragile equipment.
Summary of the invention
The purpose of this utility model is the defective that exists in the above-mentioned prior art in order to overcome, and a kind of vacuum interrupter moving conductive rod part flow arrangement is provided.
The technical scheme that adopts is:
Vacuum interrupter moving conductive rod part flow arrangement, its technical essential is:
Comprise copper conductive clip and copper conductive strips, described copper conductive clip suit, and be fixed on the moving conductive rod of vacuum interrupter; One end of copper conductive strips is fixedlyed connected with the copper conductive clip, and the other end of copper conductive strips directly is connected with moving conductive rod; Fixedly connected with following contact arm by bolt in copper conductive strips middle part.
The utility model is simple in structure, has solved during moving conductive rod and following contact arm are flexible coupling in the prior art easily heating problem, thereby reduces power consumption, also can improve vacuum circuit-breaker useful life.
Description of drawings
Fig. 1 is a kind of example structure schematic diagram of the present utility model.
Embodiment
Vacuum interrupter moving conductive rod part flow arrangement is to install part flow arrangement on the moving conductive rod 2 of vacuum interrupter 1.Described part flow arrangement comprises copper conductive clip 3 and copper conductive strips 4.Copper conductive clip 3 is installed and is fixed on the moving conductive rod 2 of vacuum interrupter, and copper conductive strips 4 one ends are fixedlyed connected with copper conductive clip 3, and its other end directly is connected with moving conductive rod 2, and this connecting portion is positioned at copper conductive clip 3 belows.Fixedly connected with following contact arm 5 by bolt in the middle part of copper conductive strips 4.
In vacuum circuit-breaker, electric current enters through last contact arm 6, vacuum interrupter 1, moving conductive rod 2, by copper conductive strips 4 and 5 outputs of following contact arm, i.e. electric current on moving conductive rod 2, again through the copper conduction of copper conductive strips 4 be with 8 and the copper conduction enter down contact arm 5 after being with 9 to shunt.Last contact arm 6, vacuum interrupter 1 (removing the moving conductive rod part) and following contact arm 5 usefulness poured with epoxy resin form an integral sealing structure.Moving conductive rod 2 lower surfaces are connected with insulated tension pole 7.
