Embodiment Construction

[0054] Please check figure 1 , a bus-type isolating and grounding combination switch, which includes a housing 100 , a first conductor 200 , a second conductor 300 , a grounding contact 400 , a moving contact 500 and a driving mechanism 600 .

[0055]The housing 100 has two first openings 130 disposed along a first direction 110 and two second openings 140 disposed along a second direction 120 , and the first direction 110 and the second direction 120 are perpendicularly disposed. The two first openings 130 are all connected with a first insulating disk 150, and a first opening 130 and a first insulating disk 150 corresponding to the first opening 130 (for example, the first opening 130 and the upper side in the figure A tube body 160 that can expand and contract along the first direction 110 is disposed between the upper first insulating disks 150 ), and the tube body 160 is, for example, a corrugated tube. The second opening 140 is connected with a second insulating disc 17...

Abstract

The invention discloses to a mother linear isolated grounding combined switch which comprises a shell body, a first conductor, a grounding contact, a second conductor and a moving contact. The shell body has two first openings set in the first direction and two second openings set in the second direction, and the first direction is vertical to the second direction. A first static contact is directly and concavely set on the first conductor. The grounding contact is connected with the shell body and arranged in the shell body. A connection seat is convexly set within the inner end of the second conductor is bent into a concave connection seat. The connection seat is provided with a second static contact, a moving channel is formed in the second static contact, is vertical to the first direction and is located between the first static contact and the grounding contact. The moving contact can be linearly connected in the moving channel in a movable way, and the moving contact moves linearly to contact the first static contact and the grounding contact selectively. In addition, the axis of the first static contact, the moving channel of the second static contact, the moving route of the moving contact and the axis of the grounding contact are coincident and paralleled to the second direction.

Description

technical field [0001] The invention relates to a busbar type isolating and grounding combination switch. Background technique [0002] The existing busbar-type isolating and grounding combined switch mainly includes two types: the first type such as DE19825386 disclosed in the German patent database on May 28, 1998; the second type such as ZL97115633 disclosed in the Chinese patent database on February 18, 1998 .6. The invention title of ZL97115633.6 is "An Isolation / Earth Switch for Metal-sealed Gas-Insulated High-Voltage Switchgear", which has: [0003] ①. A first fixed contact connected to the first inner conductor; [0004] ②. A second fixed contact connected to the second inner conductor; [0005] ③, a fixed ground contact; [0006] ④. A moving contact, which can move linearly in the contact housing forming the second fixed contact; [0007] ⑤. Each of the first and second fixed contacts and the ground contact has a central axis, and the movement path between the ...
