Description of the Related Art In general, a gas insulated switchgear drives a shut-off unit and a movable contact provided with a fixed contact and a movable contact which can be opened in a container filled with an insulating gas such as SF 6 gas. An operating device provided outside the container of the shut-off unit, a high-voltage conductor, an insulating spacer, and a gas bus comprising a gas bus container. It is known that, when assembling or the like, if metallic foreign matter enters the container of the shut-off portion or the gas bus container for some reason, the withstand voltage performance in the gas or on the surface of the insulator is reduced. For this reason, various methods for removing metallic foreign substances have been proposed.

As described in Japanese Patent Publication No. 936, a high-voltage conductor and an insulating spacer supporting the high-voltage conductor are arranged in a gas bus container, and a vibration device for applying mechanical vibration to the gas bus container is provided outside. At the same time, a container for capturing metal foreign matter is provided near the insulating spacer. With such a configuration, the metal foreign matter driven by the vibration applied by the vibration device is captured before adhering to the insulating spacer, thereby preventing the creeping withstand voltage performance of the insulating spacer from being deteriorated by the metal foreign matter. I am trying to do it.

ある。The above prior art requires a vibrating device, a considerably large vibrating force, and a nodal section which does not vibrate due to the natural vibration mode of the gas bus container itself. Therefore, there is a disadvantage that the metallic foreign matter located at the node is difficult to move, and the metallic foreign matter accumulates at the node of the vibration. The metal foreign matter may move due to a high voltage applied to the gas insulated switchgear, but there is a problem that the withstand voltage performance is reduced.

Is relatively large. For this reason, at the time of the shutoff operation, the vibration caused by the operation of the operation device 20 and the puffer type gas shutoff unit 9 is transmitted to the container 7. At this time, if metal foreign matter is mixed in the container 7, the metal foreign matter moves in the container 7 due to the vibration. However, since a unique vibration mode is generated in the container 7, the metal foreign matter that has reached the node with small vibration is difficult to move. As a result, the metallic foreign matter accumulates at the nodes of the vibration.

Such a portion serves as a reinforcing portion for the container 7 and serves as a node for vibration of the container 7. As described above, since the metal capturing containers 25 are provided in a plurality of portions serving as nodes of vibration, the metal foreign matter moved by the vibration of the container 7 is captured by the nearby metal foreign material capturing container 25. The captured metal foreign matter is not moved by the high voltage applied to the cut-off portion or the like, and it is possible to prevent a decrease in withstand voltage performance due to the metal foreign matter. In addition, since the container 25 for capturing metallic foreign matter is formed integrally with the container 7 by casting, the device can be manufactured at low cost.
In addition, the number of containers 25 can be reduced by using the container 25 as a handhole for internal inspection or by installing an adsorbent for absorbing moisture or decomposition gas.
