Embodiment Construction
[0020] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The present invention proposes an embodiment of a three-position isolating switch. Refer to Figure 1-Figure 3 As shown, it includes moving contact 1, operating mechanism 2, isolated static contact 3, intermediate static contact 4 and grounding static contact 5 which are arranged obliquely from top to bottom. The volume of the three-position isolating switch, the operating mechanism 2 is connected with an insulating main shaft 6 for driving the rotation of the insulating main shaft 6, and the insulating main shaft 6 is driven to rotate through the operating mechanism 2; the insulating main shaft 6 is connected with the moving contact A transmission assembly is arranged between the head 1 to convert the rotation of the insulating main shaft 6 into the linear motion of the movable contact 1. The transmission assem...

The invention provides a three-station isolation switch. The three-station isolation switch comprises a movable contact, an operating mechanism, and an isolation static contact, a middle static contact and a grounding static contact which are arranged in an inclined manner from the top to bottom in sequence; the operating mechanism and an insulating main shaft are in transmission connection; a transmission assembly is arranged between the insulating main shaft and the movable contact; the movable contact is arranged in the middle static contact and can move in the middle static contact up and down under the drive of the insulating main shaft, and used for being connected with the isolation static contact or the grounding static contact; a first insulating cylinder is connected between the isolation static contact and the middle static contact to enable the central lines of the isolation static contact and the middle static contact to be positioned on the same straight line; and a second insulating cylinder is connected between the middle static contact and the isolation static contact to enable the central lines of the middle static contact and the isolation static contact to be positioned on the same straight line. By virtue of the three-station isolation switch, the problem that the central lines of the three static contacts cannot be positioned on the same straight line in the assembling of the isolation switch in the prior art can be solved.
Description
technical field [0001] The invention relates to a structure of a three-station isolating switch, in particular to an improvement of the structure of a three-station isolating switch in the medium voltage field. Background technique [0002] As one of the core components of the AC metal-enclosed switchgear in the medium-voltage power system, the disconnector plays the role of carrying current, and the second is to provide an obvious maintenance fracture, hereinafter referred to as the fracture. The isolating switch is divided into two-position isolating switch and three-position isolating switch according to the function, which can provide two functions of isolating fracture and grounding fracture at the same time. The isolating fracture between the three-position isolating switches is a non-contact structure, that is, isolating static contact Two of the three contacts of the head, the middle static contact and the grounding static contact are non-contact, and there is a disc...
