GAS-INSULATED SWITCHGEAR |
| 摘要 |
To provide a gas-insulated switchgear including a metal tank that is grounded and has insulating gas filled therein, a central conductor that is extended in the tank and to which an alternating voltage is applied, an insulative coating film that is coated on an inner surface of the tank, and a coating film that is overcoated on the coating film and is formed by coating a coating material containing an insulative coating material component and a non-linear resistance material. Due to this configuration, behavior of metallic foreign matter can be suppressed in a wide range from a region having a small electric field to a region having a large electric field. |

1. A gas-insulated switchgear comprising:
a metal tank that is grounded and has insulating gas filled therein; a conductor that is extended in the tank and to which a voltage is applied; an insulative first coating film that is formed on an inner surface of the tank; and a second coating film that is formed on the first coating film, the second coating film containing an insulative material and a non-linear resistance material. |
