Amendment April 18, 1980 The scope of claims for utility model registration is amended as follows.

[Scope of claim for utility model registration] (1) Three-phase integrated type in which a lightning arrester, an instrument transformer, a disconnector, and a grounding switch are connected to the terminal of a power cable, and a current transformer is arranged on the fixed side of the disconnector. In the gas-insulated electric device, there is provided a sealed container having a branch pipe formed on a side wall, a terminal portion of the power cable housed in the sealed container, and a terminal portion of the power cable arranged between the terminal portions and housed in the sealed container. the instrument transformer; the lightning arrester disposed near the central axis extension of the terminal portion and housed in the sealed container; the current transformer housed in the branch pipe; and the center conductor of the current transformer. A gas-insulated electrical device comprising: the disconnector and the grounding switch, which are arranged near an extension of the line and housed in the sealed container. (2) A sealed container with lids attached to the upper and lower openings, and a terminal portion fixed to the lower lids.
A gas insulated electrical device according to claim 1, which is a registered utility model, comprising: an instrument transformer; and a lightning arrester fixed to the upper lid. The brief description of the drawing has been amended as follows. In the second line of page 8 of the specification, "terminal insulated conductor" is corrected to "terminal section."

Claims (1)

[Claims for Utility Model Registration] (1) Three-phase gas insulation with a lightning arrester, an instrument transformer, a disconnector, and a grounding switch connected to the terminal of a power cable, and a current transformer connected to the disconnector. In an electrical device, there is provided a sealed container having a branch pipe formed on a side wall, an insulated terminal conductor of the power cable housed in the sealed container, and a terminal insulated conductor of the power cable placed between the terminal insulated conductors and housed in the sealed container. an instrument transformer; the lightning arrester disposed near the central axis extension of the terminal insulated conductor and housed in the sealed container; the current transformer housed in the branch pipe; and the center conductor of the current transformer. 1. A gas-insulated electrical device comprising: the disconnector and the grounding switch arranged near an extension of the line and housed in the sealed container. (2) A sealed container with lids attached to the upper and lower openings, a terminal insulated conductor and an instrument transformer fixed to the lower lid, and a lightning arrester fixed to the upper lid. Gas insulated electrical device as set forth in claim 1 of the utility model registration claim
