According to the gas switch having the above configuration, the pressure in the pressurizing chamber (25) is reduced by the heat of the arc (28) generated between the fixed contact (22) and the movable contact (23) during the cutoff operation. By causing the upper culm to generate a gas flow (29) from the pressurization chamber (25) toward the exhaust chamber (26) through the exhaust port (27), and spraying the gas flow to the arc (28),
The effect of the cold comb 11 is enhanced and the arc (28) can be quickly extinguished.

However, according to the above switch, the pressure in the back pressure chamber (25) cannot be increased much in the small current range, so the pressure in the booster chamber (25) cannot be increased.
There is a problem in that it is not possible to increase the outflow rate of gas from the arc, and as a result, it is not possible to sufficiently cool the arc.

In order to address this problem, I installed a buffer.
However, both methods have the drawbacks of complicating the structure and being expensive, especially those with a buffer added. However, when the pressure in the pressurizing chamber and the pressure in the buffer are approximately the same, the disadvantage is that the gas cannot be sprayed effectively.

With the above configuration, when the movable contactor (13) is lowered to perform the breaking operation, the outer partition member (14a
) can be lowered together with the movable contact (13). At this time, since the inner partition member (14b) is immovably fixed, the pressurization chamber (15) can be contracted in response to the downward stroke of the outer partition member (14a). This bundling forcibly pressurizes the gas in the pressurization chamber (15) and the exhaust port (13) of the movable contact (13).
17) (see Figure 2). That is, the pressure due to mechanical compression is 1-Vf, and the pressure due to arc heat is J and 10d? Which synergistic da J Song 31, very ♀
A gas flow at a high speed can be blown against the arc.The mechanical pressurization accompanying the lowering of the outer partition member (14a) must always be constant. As a result, the arc can be effectively cooled even in a small current range where there is little effect on arc heat.
