Since the conventional gas insulated switchgear is configured as described above, the cable head 10, the lightning arrester 11, the voltage transformer 12, and the disconnector 13 are connected to one another.
Since the devices are housed in one disconnector container 12, the problem that these devices must be housed in individual containers is solved, but there are the following problems. In the case of Conventional Example 1, the cable head 10, the lightning arrester 11, and the voltage transformer 1
Since 2 is juxtaposed at the lower part of the disconnector container 10a,
With diameter D 1 of the disconnector vessel 10a is increased, lightning arresters 11 and contact and separation of the current path of the voltage transformer 12 (e.g.,
(The lightning arrester 11 and the voltage transformer 12 are electrically separated from the current path or removed from the disconnector container 10a during the withstand voltage test.)
There was a problem that was difficult. In Conventional Example 2, when the three-phase lightning arrester 11 and the three-phase voltage transformer 12 are accommodated in the disconnector container 10a, the diameter of the disconnector container 10a can be reduced. However, when accommodating the three-phase surge arrester 11 and the single-phase voltage transformer provided in one of the three phases in the disconnector container 10a, the disconnector container 10a
There is a problem that the empty space is larger in the upper part than in the lower part, and the diameter of the disconnector container 10a is larger than necessary. Further, since the lightning arrester 11 and the voltage transformer 12 are arranged at positions facing each other with the disconnector 13 interposed therebetween, there is a problem that it is difficult to connect and disconnect the lightning arrester 11 and the voltage transformer 12 to and from the current path. .

However, the arrangement relationship between the lightning arrester 24 and the single-phase voltage transformer 25 is determined by the insulation distance between each lightning arrester 24, the single-phase voltage transformer 25, and the disconnector tubular container 23A. Similarly, the positional relationship between the connection conductor 26a and the cable head 23 is determined by the insulation distance between each connection conductor 26a, each cable head 23, and the disconnector tubular container 23A. As shown in FIGS. 2 and 3, when the lightning arrester 24, the single-phase voltage transformer 25, the connection conductor 26a, and the cable head 23 are arranged in the disconnecting switch tubular container 23A, The area occupied by the disconnector 25 and the area occupied by the connection conductor 26a and the cable head 23 are minimized. At this time, when the cross-sectional shape of the disconnector tubular container 23A is elliptical, the disconnector tubular container 23A crosses The area can be almost minimized. Therefore, the cross-sectional shape of the disconnector tubular container 23A is preferably an ellipse. Similarly, it is desirable that the shape of the circuit breaker container 1a in the cross section is also elliptical. Further, when the disconnector tubular container 23A is a divided container, the cross-sectional shape of each divided container may be different.
