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 lightning arrester; the instrument transformer 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) Utility model registration claim 1 comprising a sealed container with lids attached to the upper and lower openings, and a terminal device transformer fixed to the lower lid.
Gas insulated electrical equipment as described in Section. (3) A gas insulated electrical device according to claim 1, which is a utility model and includes a disconnector comprising a fixed part supported by a center conductor and a movable part supported by an end part . (4) The gas-insulated electrical device according to claim 1, which is equipped with a grounding switch in which the fixed part is disposed near the extension line of the central axis of the movable part of the disconnector. The brief description of the drawing has been amended as follows. "Terminal insulated conductor" on page 8, line 15 of the specification 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. a lightning arrester, the instrument transformer 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. 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, a terminal insulated conductor and a lightning arrester fixed to the lower lid, and an instrument transformer fixed to the upper lid. A gas insulated electrical device according to claim 1 of the utility model registration claim. (3) A gas insulated electrical device according to claim 1, which is a utility model and includes a disconnector consisting of a fixed part supported by a center conductor and a movable part supported by terminal insulated conductors.
