At present, the outer chopper of railway user typically adopts single-phase single-pole or single-phase bipolar.The mode of production of domestic manufacturer is big It is many to repack single-phase bipolar into by model of this type product of ZW7-40.5, and adopt spring mechanism;And some foreign capitals are looked forward to Industry is mostly by the way of single-phase single-pole, and product construction adopts permanent magnet mechanism.
According to the difference of railway contact line power supply mode, different railway choppers can be selected.China's major part railway is used Chopper adopts indoor type, and it had both been mountable in indoor grid formula interval, was also mountable to electric railway special switch In cabinet.With the continuous stretching of railway electrical network, complete cabinet is built in some remote mountain areas, and cost will be obviously improved.And it is outdoor Single-phase single-pole railway chopper adopts external import substantially, and is driven using permanent magnet mechanism.Permanent magnet mechanism circuit-breaker With being unable to closing by hand this congenital shortcoming, therefore, design the railway chopper that a spring mechanism is driven and just show Obtain particularly important.
The content of the invention
The technical problems to be solved in the utility model is:There is provided a kind of energy closing by hand, cost-effective 27.5kV families Outer single-phase railway vacuum circuit breaker special, solves traditional railway chopper and has and be unable to closing by hand, the problem of high cost.
In order to solve above-mentioned technical problem, the technical solution of the utility model there is provided a kind of 27.5kV outdoor single-phases ferrum Road vacuum circuit breaker special, it is characterised in that including upper supporting column, is fixed with outlet on upper supporting column, vacuum interrupter is located at upper In pillar, lower supporting rod below upper supporting column, is provided with, between upper supporting column and lower supporting rod, is provided with lower outlet, the bottom of lower supporting rod is fixed on machine On structure casing, insulated tension pole in lower supporting rod, is provided with, the lower end of insulated tension pole is connected with the drive mechanism in mechanism casing, and insulation is drawn The upper end of bar is connected through lower supporting rod with vacuum interrupter, is provided with and is flexible coupling in upper supporting column below vacuum interrupter, soft The upper end of connection is connected with vacuum interrupter by conductive clamp, and the lower end being flexible coupling is connected with lower outlet.
Preferably, one end of described upper outlet and lower outlet one end are longer than the edge of upper supporting column, one end of upper outlet The both sides of upper supporting column are respectively arranged on lower outlet one end, the other end of upper outlet and the lower outlet other end are positioned at the edge of upper supporting column On/within.
Preferably, described upper outlet is arranged for level to the right;Lower outlet is arranged to the left for level.
Preferably, the side of described mechanism's casing is " 7 " font structure.
Preferably, it is fixedly connected by copper sheathing between the described lower end being flexible coupling and lower outlet.
Preferably, the upper end of described insulated tension pole is connected with vacuum interrupter by connecting rod.
This utility model simple structure, makes the upper outlet of original bilateral wiring design, lower outlet into monolateral wiring design, Save cost;Also by original rectangle mechanism case structural reform into " 7 " font casing, occupation of land space is saved, product is reduced Setting height(from bottom);To directly be flexible coupling and lower outlet connection, save Master Cost, more economically, and also it is new by this practicality Type can closing by hand, it is convenient to use.
