続されている。Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of a gas insulated switchgear according to an embodiment of the present invention, which is configured based on the circuit configuration of FIG. 7 described above. The basic configuration of each phase is the same as that of FIG. Detailed description is omitted. The shut-off portion containers 6a, 6b, 6c having the largest outer diameter have three phases juxtaposed as in the prior art. An upper container 9b connected to the outlet portion 4b of the intermediate-phase shut-off portion container 6b, and a lower container 10b located below the upper container 9b.
Is exactly the same as that of FIG. However, the other two-phase upper containers 9a and 9c located at both ends and the lower containers 10a and 10c located therebelow have the same basic configuration as that of FIG. The three phases are arranged substantially in parallel with a phase distance 11A smaller than the conventional phase distance 11. That is, the two phases located at both ends are a center line parallel to the phase direction of the shutoff unit containers 6a and 6c,
The upper containers 9a and 9c and the lower container 10
a and 10c are arranged so as to be shifted from the axis parallel to the phase direction. Therefore, since it is not possible to simply connect the displaced shut-off portion containers 6a, 6c and the upper side containers 9a, 9c as in the middle phase, the outlet portions 4a, 4c are positioned with respect to the above-mentioned center line and axis. Is formed at a position shifted in the circumferential direction of the blocking portion containers 6a and 6c as compared with the medium phase so as to have an angle θ,
At least through the outlets 4a and 4c, the shutoff container 6
a, 6c and the upper containers 9a, 9c. Although not shown in the figure, the shut-off portion containers 6a, 6c and the lower containers 10a, 10c are also connected by similar outlets 5a, 5c.

きる。When the gas insulated switchgear for one line is configured as described above, and the gas insulated switchgear for two lines is juxtaposed, the upper containers 9a and 9d are typified as shown in FIG. Between the two phases, that is, between two gas-insulated switchgears.
An opposing distance 8A longer than before can be obtained. With the facing distance 8A, the disconnectors DS1, D configured as shown in FIG. 9 are connected to the upper and lower containers for the three phases.
It is possible to obtain a space for maintaining and inspecting the actuators 20 to 25 for S2, DS3 and the grounding devices ES1, ES2, ES3. In addition, as can be seen from the above description, since the positions of the blocking portion containers 6a, 6b, and 6c are the same as those in the related art, the entire installation area does not change. In other words,
If the conventional line-to-line distance 8 shown in FIG. 8 provides sufficient space for maintenance and inspection of the actuators 20 to 25, the two-line gas insulated switchgear according to the configuration of FIG. The installation area can be reduced by arranging closer than before.

In this embodiment, the upper container 9b and the lower container 10b of the middle phase of the gas insulated switchgear for one line are configured on the opposite side to those of the other phases. The middle-phase shut-off portion container 6b forms outlets 4b and 5b on the left side in the figure, and connects the upper container 9b and the lower container 10b to these outlets 4b and 5b, while the other ends are connected to the other. The two phases at both ends of the drawing lead out the outlets 4a and 5a to the right in the figure, similarly to the embodiment of FIG.
The axes of the upper containers 9a, 9c and the cut-off portion containers 6a, 6c
And the center line parallel to the phase direction is made different, and the axis of the former is located inside the center line of the latter. In this way, if the two-phase upper containers 9a and 9c at both ends are brought close to each other, an opposing distance larger than the opposing distance 8A shown in FIG. 1 can be obtained.

That is, as shown in FIG. 6, two-phase outlets 4a and 4c and outlets 5a and 5
While c is formed at the same level, the lead portions 4b and 5b of the middle phase are formed at a level different from that of the two-phase lead portions. Therefore, compared with the case where the outlets of each phase are all at the same level, the distance between the upper containers 9a and 9c on both sides is smaller.
Further, the space between the lower containers 10a and 10c can be made closer to each other. According to the gas insulated switchgear having such a configuration, when a plurality of lines are provided as shown in FIG.
The opposing distance 8A formed between the lines can be further increased.

できる。In each of the above embodiments, the opposing distance 8A is secured between the lines, and the maintenance and inspection of the operating device is performed using the space obtained thereby. Even with a gas insulated switchgear for one line, an opposing distance can be secured between any two phases, and maintenance and inspection of the operating device can be performed from this opposing portion. In this case, in the two phases forming the facing portion, the axes of the upper container and the lower container are preferably located outside the center line parallel to the phase direction of the respective blocking container. In other words, the description will be made with reference to FIG. 1. Three phases represented by the upper containers 9 a, 9 b, and 9 c constitute one circuit, and
a and 6d are brought close to each other, and the space obtained by the opposing distance 8A between the upper containers 9a and 9d can be used for maintenance and inspection of the operating device. Further, in each of the embodiments described above, the gas insulated switchgear connecting the line side and the bus side has been described, but the present invention can also be applied to a gas insulated switchgear connecting the busbar and the transformer or a gas insulated switchgear of other specifications. Further, in the above-described embodiment, the opening between the shut-off portion containers 6a and 6c and the upper containers 9a and 9c and the lower containers 10a and 10c disposed on the axes deviated from the center line parallel to the phase direction. Although they are directly connected by the outlets 4a and 4c and the outlets 5a and 5c, a connecting container may be interposed between them. However, if the connection is made directly by the spout, the structure is simplified, and the axial lengths of the upper containers 9a and 9c and the lower containers 10a and 10c can be reduced.

Since the axes of the container and the lower container are provided so as to be positioned, and the operation devices for the disconnector and the grounding device are provided at the opposing portions of these two phases, the above-mentioned center line and the axis can be provided without increasing the installation area. Thus, a longer opposing distance can be obtained than in the conventional configuration in which the above-mentioned configuration is matched, and maintenance and inspection of the operating device can be easily performed using the opposing portion.
