Embodiment Construction

[0020] The embodiment of isolating switch among the present invention: as figure 1 with figure 2 As shown, the isolating switch is a HGIS / GIS isolating switch, including a housing 14 and a moving contact and a static contact assembled therein. The moving contact and the static contact are coaxially arranged relative to each other. The fracture between the heads is an isolation fracture, and the end of the moving contact and the static contact facing the isolation fracture is defined as the head, and the end facing away from the isolation fracture is the tail, and the moving contact is fixed in the housing 14 through the moving conductor. The static contact is fixed in the housing 14 through the static end conductor 5 .

[0021] The moving contact includes a cylindrical moving main contact 3, and a circular blind hole is opened on the end surface of the head of the moving main contact 3, and a moving arc fixed on the inner end surface of the closed end by a fastening screw is...

Abstract

The invention discloses an isolation switch and a conductor thereof. The conductor of the isolation switch comprises a main conductor; the head of the main conductor is integratedly provided with an annular housing-shaped head part shielding structure for sleeving the outer circumference of a moving contact or a static contact; the head part shielding structure is coaxial with a main conductor; a rotating bus is a rotating body of a curve which is bent along an arc track from the head part of the main conductor; through the combination of the traditional isolation switch conductor and the shielding housing, the surface area is increased through the head part shielding structure, and the current conduction is realized; the head part shielding structure can perform shielding on the head part of the main conductor and uniformly isolates the power plant inside the switch; in the meantime, the integration design of head part shielding structure on the head part of the main conductor eliminates the bolt connection between the traditional conductor and the shielding housing, and reduces the kinds and amount of the parts inside the isolation switch. The compact structure design of the conductor enables the isolation switch to be simple and easy to disassemble.

Description

technical field [0001] The invention relates to an isolating switch and its conductor. Background technique [0002] GIS (GasInsulatedmetal-enclosedSwitchgear, SF6 gas-insulated metal-enclosed switchgear) / HGIS (HalfGasInsulatedmetal-enclosedSwitchgear, composite SF6 gas-insulated metal-enclosed switchgear) due to its compact structure, small footprint, strong environmental tolerance, safe operation, With many advantages such as beautiful appearance, it has been widely used in substations in recent years. GIS / HGIS, as the core equipment of super-large substations, is mainly composed of circuit breakers, disconnectors, grounding switches, transformers, lightning arresters, cable terminals, busbars, bushings and other components. The outside is protected by a metal shell, and the inside of the shell Filled with SF6 insulating gas. [0003] The isolating switch is one of the main components in the composition of GIS. Its function: to carry the rated current of the circuit and ...
