[Brief explanation of the drawing]

Figure 1 is a longitudinal sectional view of one embodiment of this invention;
The figures are a sectional view taken along the line - - in FIG. 1, FIG. 3 is a conventional standard skeleton connection diagram, and FIG. 4 is a longitudinal sectional view of a conventional gas-insulated electrical device. 1...Power cable, 2...Transformer, 3...Surge arrester,
4... Disconnector, 5... Current transformer, 5b... Center conductor, 6...
Terminal insulated conductor, 18... sealed container, 18b... branch pipe.
In each figure, the same reference numerals indicate the same or equivalent parts.

Amendment April 19, 1980 The scope of claims for utility model registration is amended as follows.

[Claims for Utility Model Registration] (1) Three-phase integrated type comprising a transformer, lightning arrester, and disconnector connected to the terminals of a power cable, and a center conductor for the current transformer connected to the disconnector. A gas-insulated electrical device comprising: a sealed container in which a branch pipe is formed and a terminal portion of the power cable is housed therein;
The transformer is arranged between the terminal parts and housed in the sealed container, the lightning arrester is arranged in the vicinity of the central axis extension of the terminal part and is housed in the sealed container, and the lightning arrester is housed in the branch pipe. A gas insulated electrical device comprising: the current transformer; and the disconnector disposed near an extension of the center conductor of the current transformer and housed in the sealed container. (2) Utility model registration claim 1 comprising a terminal part and a transformer fixedly supported on one lid of a sealed container, and a lightning arrester fixedly supported on the other lid.
Gas insulated electrical equipment as described in Section. (3) The gas-insulated electrical device according to claim 1, which is a utility model and includes a central conductor fixedly supported by an insulating spacer attached to a branch pipe. The brief description of the drawing has been amended as follows. "Terminal insulated conductor" on page 7, line 9 of the specification is corrected to "terminal section."

Claims (1)

[Claims for Utility Model Registration] (1) Three-phase integrated gas insulation comprising a transformer, lightning arrester, and disconnector connected to the terminals of a power cable, and a current transformer connected to the disconnector. In an electrical device, a sealed container in which a branch pipe is formed and contains a terminal insulated conductor of the power cable, the transformer arranged between the terminal insulated conductors and housed in the sealed container, and a center of the terminal insulated conductor. The lightning arrester is arranged near the extension of the shaft and housed in the sealed container, the current transformer is housed in the branch pipe, and the current transformer is arranged near the extension of the central conductor of the current transformer and housed in the sealed container. A gas-insulated electrical device comprising the above-mentioned disconnector. (2) The gas-insulated electrical device according to claim 1 of the utility model registration claim, comprising a terminal insulated conductor and a transformer fixedly supported on one lid of a sealed container, and a lightning arrester fixedly supported on the other lid. . (3) The gas-insulated electrical device according to claim 1, which is a utility model and includes a central conductor fixedly supported by an insulating spacer attached to a branch pipe.
