Embodiment
To become apparent the utility model, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
It should be understood that these embodiments are merely to illustrate the utility model rather than limit scope of the present utility model.This
Outer to should be understood that after the content of the utility model instruction has been read, those skilled in the art can make each to the utility model
Plant and change or change, these equivalent form of values equally fall within the application appended claims limited range.
The utility model is a kind of built-in insulation pull bar column support type vacuum circuit breaker, as shown in figure 1, it includes pole 1, frame
Frame and driving member 2, column 3.Pole 1 is fixed on the frame 2, and framework 2 is supported connection by column 3.
As shown in Figure 2 and Figure 3, pole 1 includes upper supporting column and lower supporting rod, and lower wire outlet seat is provided between upper supporting column and lower supporting rod
7, the top of upper supporting column is provided with upper wire outlet seat 4, and vacuum interrupter 5 is built in the upper supporting column of pole 1, upper wire outlet seat 4 and vacuum
The static side connection of arc-chutes 5, conductive clip 8 is loaded on the moved end of vacuum interrupter 5, and moves together therewith；6 one end be flexible coupling with leading
