Embodiment Construction

[0038] Specific embodiments of the present invention will be described in detail below in conjunction with technical solutions and accompanying drawings.

[0039] The structure of the 10kV outdoor high-voltage isolating switch of the present invention is a three-phase type, and each phase has the same structure, and is linked by interphase tie rod components.

[0040] Such as Figure 2-6 As shown, the 10kV outdoor isolating switch contacts include: moving contact 1, static contact 3 and connector 4.

[0041] One end of the moving contact 1 is a planar body 1.1 for connecting the conductive plate, and the other end is an alloy head 1.4 with a semi-spherical structure, which can be inserted into the contact finger 3.2 of the static contact 3 . The middle part of the moving contact 1 is a cylinder 1.2, and the hemisphere 1.4 is a copper alloy, which is screwed on the threaded body 1.3 at one end of the cylinder 1.2. Screw holes are provided on the surface of the plane body 1.1 ...

Abstract

The invention discloses a 10kV outdoor isolating switch contact and an isolating switch. The contact comprises a moving contact, a static contact and a connecting piece. The static contact comprises screw assemblies, contact fingers and spring rings, the contact fingers are bent inwards to form hooks, and the spring rings sleeve the hooks. One end of the connecting piece is a hexahedron, and the six faces of the hexahedron are each connected with one contact finger through the corresponding screw assembly. The moving contact and the static contact are in cylindrical surface connection, so thatthe moving contact and the static contact can be effectively clamped, and heating caused by poor contact is prevented.

Description

technical field [0001] The invention belongs to the technical field of isolating switches, and in particular relates to a 10kV outdoor isolating switch contact and an isolating switch. Background technique [0002] Isolating switch is a high-voltage electrical appliance that divides and closes the circuit without load current, and is used to change the circuit connection or isolate the circuit or equipment from the power supply. At present, the 10kV outdoor isolating switch used in my country's substations is opened and closed at the same time with two columns, the rotation method is to use the ceramic column to rotate, and the connection method is to use the spring self-compressing type. This kind of isolating switch has a complex structure, and the rotating and connecting parts are not in good contact, which often causes heat, sparks, and welding. Long-term thermal expansion and contraction also cause stress changes in the porcelain bottle column. The broken porcelain bot...
