Although the height of the shutoff tank 14 is reduced, the outer diameter dimension is increased, which conflicts with the demand for a smaller installation area. The lower height of the shut-off tank 14 limits the number of the current transformers 3 to be installed, which is disadvantageous for installing a large CT capacity. Further, since the circuit breaker 2 generates a large amount of high-temperature and high-pressure gas, a container for covering the current transformer 3 in a state close to a completely sealed state is required, which causes a high cost.

Next to the current transformer 3 in the lightning arrester tank 23, the lightning arrester 5 is provided in an upright state on the conductor 24. In this embodiment, the spacer 28 is provided at a position as high as possible in order to increase the height of the cable tank 16 and facilitate the connection of the load busbar to the cable head 4.

Only the cable head 4 is accommodated in the cable tank 16 and no current transformer, disconnector, grounding device or lightning arrester is accommodated. This is because the insulating gas in the cable tank 16 is removed and the voltage is applied from the flange portion during the test of the cable DC withstand voltage, so that the parts requiring precision are not accommodated. Also, in gas-insulated switchgear for overseas export, cable head connection parts are mostly supplied by overseas users and installed locally,
There is also a reason to improve reliability.

Regarding the current transformer 3, the sectional view on the left side of the figure shows the case where the number of current transformers is increased, and the sectional view on the right side shows the case where the number is small. And even if the capacity increases, it can respond to the requests from users with almost no restrictions. By removing the operation box 27 and arranging the operation devices 25 and 26 outside the side surfaces of the lightning arrester tank 23, the lightning arrester tank 23 can be extended downward and more current transformers 3 can be provided.

On the other hand, since only the cable head 4 is accommodated in the cable tank 16, the height of the cable tank 16 can be freely selected. Further, even if the insulating gas in the cable tank 16 is removed during the cable DC withstanding voltage test, there is no component other than the cable head 4, so that there is less risk of moisture absorption by the component.

(D) Fourth Embodiment In this embodiment, the disconnector 8c and the grounding device 7c in the lightning arrester tank 23 in the third embodiment are moved to the upper part, the lightning arrester 5 is moved to the lower part, and the position of the spacer 9 is also changed. It was moved down. Since the other points are the same as those in the third embodiment, the description thereof will be omitted.

As can be seen from the above description, according to the gas-insulated switchgear according to the present invention, the current transformer is accommodated in the cable tank or the like other than the shutoff tank. You can increase the number of current transformers. In addition, since there is no breaker for generating hot gas in the cable tank, there is no risk of impairing reliability due to deterioration of the current transformer, in other words, a container etc. for protecting the current transformer from hot gas is unnecessary. Will lead to cost reduction.

On the other hand, since there is no current transformer in the shutoff tank, the outer diameter of the tank can be reduced, which leads to downsizing of the gas insulated switchgear. Further, since the space where the current transformer is arranged in the shutoff tank can be used as a space for maintenance, it is easy to inspect the arc extinguishing chamber in the breaker, replace the parts, and clean the parts.
