The pole is modular construction, is directly assembled on the breaker mounting rack；
Idler wheel is installed on the breaker mounting rack, and is connect with being flexible coupling with major loop, ring network cabinet body side wall is set
There is guide rail, the breaker mounting rack is mounted on the guide rail.
It is provided by the embodiment of the utility model withdrawable it can be seen from above-mentioned technical solution provided by the utility model
Air insulation ring network cabinet vacuum circuit breaker has many advantages, such as that small in size, function is integrated, high reliablity, can extract out, both solved
The leakage of SF6 gas-insulated ring network cabinet gas and explosion issues also solve solid insulation ring main unit product quality shakiness and cost
High disadvantage, it is easy to maintain and can operate normally in the presence of a harsh environment.

Specific embodiment
The utility model embodiment will be described in further detail below.Do not make in the utility model embodiment in detail
The content of description belongs to the prior art well known to professional and technical personnel in the field.
The withdrawable air insulation ring network cabinet vacuum circuit breaker of the utility model, preferable specific embodiment
It is:
Including pole, mechanism, breaker mounting rack, breaker main shaft, running part；
The pole is modular construction, is directly assembled on the breaker mounting rack；
Idler wheel is installed on the breaker mounting rack, and is connect with being flexible coupling with major loop, ring network cabinet body side wall is set
There is guide rail, the breaker mounting rack is mounted on the guide rail.
The ring network cabinet body side wall is equipped with upper rail and lower guideway, and the idler wheel of breaker mounting rack lower end is put into
On the lower guideway, breaker mounting rack upper end is caught in the upper rail.
Using the guide rail by behind the designated position of breaker push-in ring network cabinet, it is screwed, and with being flexible coupling
Breaker is connected on major loop.
The withdrawable air insulation ring network cabinet vacuum circuit breaker of the utility model, overcomes present in the prior art
Drawbacks described above has many advantages, such as that small in size, function is integrated, high reliablity, can extract out, both solved SF6 gas-insulated ring network cabinet
Gas leakage and explosion issues also solve solid insulation ring main unit product quality shakiness and the high disadvantage of cost, easy to maintain
And it can operate normally in the presence of a harsh environment.
Specific embodiment:
As shown in Figure 1, Figure 2, Figure 3 shows.
The utility model uses modularized design, including 6 most of assemblings, respectively pole 1 (vacuum interrupter),
Mechanism 2, breaker mounting rack 3, breaker main shaft 4, idler wheel 5, running part 6, wherein pole 1 (vacuum interrupter) is by mould
