Embodiment 1

[0067] Such as Figure 4 As shown, the GIS includes a GIS body 21 and a cable terminal connection device, and the cable terminal connection device is used to connect the power cable and the GIS body 21 . Among them, the GIS ontology is an existing mature product, so it will not be repeated here.

[0068] Such as Figure 4 and Figure 5 As shown, the cable terminal connection device includes a cylinder 22, the cylinder 22 extends along the vertical direction, the cylinder 22 is provided with a cable terminal 23, the lower end of the cable terminal 23 is used to connect the power cable, and the upper end of the cable terminal 23 is fixed with a The first static contact 24.

[0069] In this embodiment, the cylinder body 22 has a first cylinder mouth and a second cylinder mouth, the first cylinder mouth is set to the right, the first cylinder mouth is docked with the GIS body 21, and the first insulator 30 is fixed between the first cylinder mouth and the GIS body 21, The seco...

Embodiment 2

[0083] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the cylinder body 22 includes a cylinder body and a transition cylinder 31, one end of the transition cylinder 31 is connected to the cylinder body through a flange structure, and the other end of the transition cylinder 31 is The second barrel mouth is formed, and the end cap 28 is fixedly connected to the transition barrel 31 . In this embodiment, the cylinder body is not equipped with a transition cylinder, and the end cap is directly fixedly connected to the cylinder body. During the pressure test, after the end cap is removed, the transition cylinder is first installed on the cylinder body, and then the pressure sleeve is installed. .

Embodiment 3

[0085] The difference between this embodiment and Embodiment 1 is that, in Embodiment 1, the second insulator 27 is a pot insulator. In this embodiment, the second insulator is a flat insulator.

Abstract

The invention relates to a cable terminal connecting device for a GIS and the GIS. The cable terminal connecting device for the GIS comprises a cylinder body, an end cap, a first insulator, a second insulator, and a moving contact. A cable terminal is arranged in the cylinder body, the cable terminal is conductively connected with a first static contact, and the cylinder body is provided with a first cylinder opening and a second cylinder opening; the end cap is fixedly arranged on the second cylinder opening and is used for plugging the second cylinder opening, and the end cap is dismounted during a withstand voltage test; the first insulator is fixedly arranged at the first cylinder opening, a second static contact is fixedly arranged on the inner side of the insert on the first insulator, and the second static contact is used for being conductively connected with the GIS body; the edge of the second insulator is fixedly arranged between the second cylinder opening and the end cap, and a contact seat is fixedly arranged on the inner side of an insert on the second insulator; and the moving contact is hinged on the contact seat, the moving contact has three working positions in the swinging process, the moving contact is conducted with the first static contact at the first working position, the moving contact is conducted with the first static contact and the second static contact at the second working position, and the moving contact is conducted with the second static contact at the third working position.

Description

technical field [0001] The invention relates to a GIS cable terminal connection device and the GIS. Background technique [0002] The cable terminal connection device for GIS is a necessary device to connect the power cable and the GIS body. Since the on-site withstand voltage test parameters of the GIS body and the power cable are inconsistent, it is necessary to conduct a withstand voltage test independently for the two. [0003] At present, the existing cable terminal connection devices for GIS such as figure 1 As shown, a cylinder 12 is included, and a cable terminal 13 is provided inside the cylinder 12. The lower end of the cable terminal 13 is connected to the power cable, and the upper end of the cable terminal 13 is fixed with a cable terminal contact 14, and the cable terminal contact 14 is connected through the first connection. The conductor 15 and the second connecting conductor 16 are electrically connected to the GIS body 11 . When performing withstand volta...
