Road device pole appearance and size and saving cost of manufacture.
To reach above-mentioned purpose, the utility model is achieved using following technical scheme.
A kind of medium pressure gas insulated metal closed switch equipment, including circuit breaker polar, the circuit breaker polar include exhausted
Edge housing, upper bracket, vacuum interrupter, flexible link, lower conducting end, insulated tension pole.The upper bracket is threadedly connected to described
The static conductive rod of vacuum interrupter, the upper bracket, vacuum interrupter and lower conducting end are poured into a mould by mould material and are integrated,
The mould material is formed as the insulation shell, and the moving conductive rod of the vacuum interrupter is threadedly connected to the insulation and draws
Bar, the flexible link is connected between the moving conductive rod and the lower conducting end, for the output of electric current.
Used as a kind of preferred scheme of the flexible link structure, the flexible link includes butterfly gasket, metal is soft connects
Line, the butterfly gasket is set between the moving conductive rod, insulated tension pole, and one end of the metal soft wiring is set in described
Between moving conductive rod, saucer washer, the other end of the metal soft wiring is bolted to the lower conducting end.

Compared with prior art, advantage of the present utility model and beneficial effect are：The utility model medium pressure gas insulation gold
Circuit breaker polar in category sealing switch equipment compared to there is an existing telescopic circuit breaker polar, upper bracket, vacuum interrupter with
And lower conducting end is fixed as one by the form poured into a mould, not only reduces detachable part and also reduce the outer of circuit breaker polar
Shape size, the insulation shell of mould material shaping is prevented has gap between upper bracket, vacuum interrupter and insulation shell, have
Effect is avoided has dust, moisture even small worm without using the phenomenon for radiating, heat dispersion being improve indirectly in gap.Compare
In the fixed sealing type circuit breaker polar made on conventional air insulated metal closed switch equipment, it optimizes electric current transmission structure,
Lower carriage necessary to conventional circuit breaker pole and conductive clip structure part are eliminated on the premise of electric current effectively output is ensured,
Both circuit breaker polar manufacturing cost had been saved, circuit breaker polar reliability of operation had been improve again.
After the detailed description of the utility model implementation method is read in conjunction with the figure, other features of the present utility model and advantage
Will become clearer.
Brief description of the drawings
Fig. 1 is the sectional view of circuit breaker polar in the utility model specific embodiment.
Specific embodiment
Specific embodiment of the present utility model is stated in detail below in conjunction with the accompanying drawings.
The present embodiment proposes a kind of medium pressure gas insulated metal closed switch equipment, including circuit breaker polar, such as Fig. 1 institutes
Show, circuit breaker polar includes insulation shell 1, upper bracket 2, vacuum interrupter 3, flexible link, lower conducting end 4, insulated tension pole 5.
Wherein, upper bracket 2 is threadedly connected to the static conductive rod of vacuum interrupter 3, in the present embodiment especially by bolt by upper bracket 2 with
Static conductive rod is fixedly connected；After upper bracket 2, vacuum interrupter 3 are fixedly connected, upper bracket 2, vacuum is gone out using mould material
Arc chamber 3 and the cast of lower conducting end 4 are integrated, and are formed as insulation shell 1 after mould material solidification, to reduce extraneous ring as far as possible
Influence of the border to vacuum interrupter 3, and pouring technology is existing mature technology, is not repeated herein；In order to ensure circuit breakers pole
The normal of post is used, the moving conductive rod of vacuum interrupter 3 is threadedly connected to insulated tension pole 5, and the output for electric current is flexible coupling
Part is then connected between moving conductive rod and lower conducting end 4.
Specifically, flexible link includes butterfly gasket 6, metal soft wiring 7 in the present embodiment, butterfly gasket 6 is set in
After between moving conductive rod, insulated tension pole 5 so that one end of metal soft wiring 7 is set between moving conductive rod and saucer washer, gold
The other end for belonging to soft wiring 7 is bolted to lower conducting end 4, to ensure the electric current output function of flexible link, due to gold
