Problems solved by technology

[0004] As far as the switch fracture of the moving contact linearly moves, the above structure is the only visible structure on the market at present, which has caused great restrictions in reducing the size of the fracture and simplifying the structure of the fracture. It is imminent to design switch fractures with different structures.

Embodiment 1

[0069] Such as figure 1 The opening state diagram of the switch fracture is shown. The switch fracture includes a moving contact and a static contact 3. The cross section of the moving contact is T-shaped. The moving contact includes a moving contact body 1 and is fixed on the side of the moving contact body 1. The conductive rod 4, the static contact 3 is provided with a through hole for the conductive rod 4 to pass through, and an insulating guide sleeve 5 is provided between the side wall of the through hole and the conductive rod 4, and the insulating guide sleeve constitutes the insulation in this embodiment. The ring, the static contact 3 is provided with a groove for inserting the movable contact body 1 of the movable contact, and the watch strap contact finger 2 is arranged on the side wall of the groove. When the moving contact body 1 of the moving contact is in contact with the static contact 3, the switch fracture is closed and the circuit is turned on; when the mov...

Embodiment 2

[0074] Embodiment 2 of the solid-sealed pole of the present invention differs from Embodiment 1 in that: Figure 4~5 There is no bellows installed in the shown vacuum interrupter, and the vacuum interrupter is sealed by the insulating guide sleeve 7 provided between the static cover plate 6 and the conductive rod 8 .

Embodiment 3

[0075] Embodiment 3 of the solid-sealed pole of the present invention differs from Embodiment 1 in that: the inside of the porcelain body or glass shell of the vacuum interrupter is vacuum, and the moving contact, the static contact and the static contact connected to the static contact The contact seat is inside the sealed housing, and the inner cavity of the static contact seat communicates with the vacuum space sealed by the sealed housing.

[0076] Embodiment 4 of the solid-sealed pole of the present invention differs from Embodiment 3 in that the space between the ceramic body or glass shell of the vacuum interrupter and the static contact seat is a closed space, and the internal cavity of the static contact seat It is also a closed space, and the sealed space of the sealed housing and the sealed cavity are relatively independent, but the medium in the two sealed cavities is the same.

[0077] In other embodiments: when the interior of the static contact seat is a closed ...

Abstract

The invention relates to a switch fracture, an arc extinguishing chamber, a solid-sealed polar pole and a circuit breaker. The switch fracture comprises a fixed contact and a direct action type movingcontact; a through hole is formed in the fixed contact; the moving contact comprises a moving contact body located on one side of the fixed contact; one side, close to the fixed contact, of the moving contact is connected with a conductive rod; the conductive rod penetrates through the through hole in the fixed contact and is insulated from the fixed contact; and the moving contact body can be close to the fixed contact through a reciprocating motion to be closed, and is separated from the fixed contact to be opened. The arc extinguishing chamber, the solid-sealed polar pole and the circuit breaker apply the switch fracture. The switch fracture adopts a reverse contact and separation mode to realize closing and opening of the switch fracture; the opening and closing directions of the switch fracture are opposite to those of a conventional switch fracture; the original same forward contact modes of the moving contact body and a fixed contact body are changed; a brand-new closing and opening mode of the switch fracture is provided; and a new idea is provided for reducing the fracture size and simplifying the fracture structure.

Description

technical field [0001] The invention relates to the field of electrical switches, in particular to a switch fracture, an arc extinguishing chamber, a solid-sealed pole and a circuit breaker. Background technique [0002] The switch is an electrical device widely used in the field of power transmission and distribution. The fracture structure is the core structure of the switch. The quality of its design directly affects the current flow performance and breaking performance of the switch. [0003] The typical fracture structure can be seen in the Chinese utility model patent with the authorized announcement number CN 205487926 U and the name of a new type of interrupter, including moving contacts and static contacts. The static contacts are connected with contact seats, and the moving contacts are connected with There is an operating mechanism, and the two are arranged at intervals along the same straight line. When the switch is closed, the moving contact moves closer to the...
