The conventional gas-insulated electrical switchgear I described in the second aspect of the body is connected to the device 1 3, the electric-undercapacity vacuum circuit breaker 6, the disconnect switch 7, and the grounding switch. Therefore, the connection portions 9 use each other. The connecting conductors 5a, 7a, and 8 are separated from each other, so it is necessary to ensure that the space between the machines or components and the insulation distance between them is also driven by the main body container 2. In addition, the vacuum circuit breaker 6 and the minute 24 must be exposed in the main body container 2 only. Therefore, this is the reason. In addition, the insulation distance between Γ becomes larger. The container 2 becomes larger. The container 2 becomes D. Fig. 9 When the safety rate of insulation resistance is increased, the body is large. As a result, since the main body container 2 must be enlarged,

Description of the invention (11) The mitigating effect will become larger, and the space insulation distance between other components around this movable electrode-side terminal 72 can be reduced. By forming such a structure, the following effects can be obtained. By passing the driving member 81 through the through hole 76a of the insulating support 76, it is not necessary to arrange the driving rod 24 above the upper insulating support 9 as shown in the conventional example in FIG. The structure of the figure can greatly reduce the height of the circuit breaker. Fig. 5 shows the switch unit, 5 (a) is a front view seen from the front side of the main body container 50, and 5 (b) is a side view. This structure has been described above, but if it is to be summarized, an insulating support 6 〇a is provided on the base 6 〇e, and then the movable contact portion 6 〇a and the fixed contact portion of the switch 6 〇 are cut off. 6 〇b is installed on the head of each insulating support 60d, and is connected to the grounding switch 5 9 at the fixed contact portion 60 a, and is connected to the grounding switch 6 1 ′ at the movable contact portion 6 〇a, and this connection is borrowed The curved surfaces are used to connect different planes around the cut-off switch 60 and the grounding switches 59 and 61, so that the housings with electric field slow conductivity are integrated with each other. The dagger is constructed as described above, that is, it does not require a conductor for connecting the cry switch 60, the grounding switch 59, 61, and can be an M-knife device. And 'by arranging the base 60 e in the cut-off switch 600, it is possible to use one base 60e to keep the separated movable contact part 60 ° a /' — the contact part 60b, and other grounding switches 59 , 61 杲 m & fixed 结 steadily binds to the cut-off switch 60, so the base 60 e of the switch unit 66.

Description of the invention (12) The operating direction of 6 0c forms up and down points 5 9 a, 6 1 a. The operating direction shape of the switch unit 6 6 is further reduced. In addition, although the ground switch 6 1 is The combination is called a switch, and it is composed of the electric connector connection part 62 and the electric connector connection part described above, that is, it does not require a connection conductor between the two, but it can be more, as shown in Figure 1. The rear part of the vacuum circuit breaker 58 and the machine configuration are the structure of the containing machine which is roughly composed as a whole, and the knot can miniaturize the main body container 50. The ground switch 5 9 and 61 can be connected to the container body 50 inward, that is, south. The switch 5 9, the cut-off switch 6 〇, and the ground open unit 66, but can also be fixedly coupled to the upper part of the ground switch 6 1 and 6 2 as the switch unit 6 6 as shown in FIG. 5. The grounding switch 6 1 and the cable head connection portion 6 2 simplify the structure of the device in the main body valley device 50. Since the switch units 66 are arranged at the bottom and connected to each other, and are U-shaped, the main body container 5q can be simplified. Compared with the conventional example shown in FIG. Figure VI-V ^ sentence view 8 5 is a bearing with shielding function. Ϋ́ 付糸糸 8 6 is a drive that can be inserted into one end of the operation shaft rnf 61c, 62c and combined.
