。Since the two breaker sections have the same basic configuration, only one breaker section will be explained. A buffer piston (not shown in detail) is fixed by an insulating support cylinder 13 fixed to the lid 9. A cylinder 3 is combined with the buffer piston, and the two constitute a compression device. A movable contact (not shown) is attached to the cylinder 3, and this movable contact is in contact with the fixed contact 10.

されている。The arc generated by the IB811 of the second-class contact is extinguished by being guided by the insulating nozzle 11 from the compressor and blown with gas. The fixed contact 10 is fixed to the lid 7 by an insulating support 13 via a conductor 12t. Between the conductor 12 and the conductor 17, there is a voltage distribution,
For example, a parallel capacitor 5 is connected. Furthermore, as can be seen from FIG. 2, the closing resistor device 18 is similarly connected.

ある。As can be seen from Figure 2, the positions of the parallel conductor r5 and the closing resistor 18 in the two breaker sections 19 and 20 are reversed. Both cutoff parts are located near the 1Ill wall of the container 1 on the opening connecting the terminals 8. The parallel capacitor 5 and the closing resistor device 18 are connected to a single breaker section 19.
IiI, which are arranged on opposite sides of 20, and which are connected to each other, are arranged so that they are almost parallel to each other. The shield cylinder 16 has a shape in which the opposite direction Il is approximately parallel to the edge, and the opposite direction Il is parallel to the inner wall of the container 1.
すなわち、対向部の曲率は反対向側の曲率よりも大きく
なされている。That is, the curvature of the opposing portion is greater than the curvature of the opposite side.
しゃ断１１１９．２０のしゃ断操作は１図示しない操作
装置によ〕機構ケース６内のリンク機構。The shutoff operation of the shutoff 1119.20 is performed by an operating device (not shown) by a link mechanism inside the mechanism case 6.

しゃ断器が得られる。Since the cutoff parts 19 and 20i are arranged apart from each other, the gases do not affect each other. Moreover, the connecting conductor 15 is a fixed contact 101i11= on the downstream side of the gas flow.
The scum contributing to arc extinguishment does not affect the insulation maintenance between the breaker parts, unlike when the 9th part is connected on the conductor 17 side to form the 2 series breaker points. That is,
When connecting conductor 15 is provided on conductor 17@, one-car breaker section 1
Since the full voltage is applied between the conductors 12 at 9.20, care must be taken to maintain insulation at 41. Shield tube 2
Also, one having the same shape as the shield tube 16 can be used. In particular, since the full voltage is applied between the shield tubes 2, a shape like the one shown in FIG. 2 results in an electric field between the shield tubes 2. Therefore, a high voltage gas breaker can be obtained with a small diameter container l.

おける電位分布を改善して容器の小塵化が図れる。As explained above, in the present invention, two cutoff parts are arranged side by side to form two cutoff points in series, and the electric field mitigation shield provided at each cutoff part has a curvature larger at the opposing part than the curvature at the opposite side. Therefore, it is possible to improve the potential distribution in this pumping configuration and reduce the amount of dust in the container.
