Novel insulation pull rod gluing structure

Abstract

The invention belongs to the technical field of an insulation pull rod used in a high-voltage switch, and particularly relates to a novel insulation pull rod gluing structure. The novel insulation pull rod gluing structure is characterized by comprising an inner joint and an insulation pull rod, wherein a shielded joint is arranged between the inner joint and the insulation pull rod, and a gluing mode between the insulation pull rod and the shielded joint is double-V-shaped-groove gluing. An arc gluing mode of an original structure is changed into a double-V-shaped-groove gluing mode, adsorption force among the inner joint, the insulation pull rod and the shielded joint is enhanced by a siphonic effect, and therefore, the inner joint, the insulation pull rod and the shielded joint made of different materials are combined into a whole so as to enhance the tensile resistance of the whole insulation pull rod; problems that an original joint is infirmly glued, arc processing difficulty is big and cost is high are solved; the impact resistance of the insulation pull rod is enhanced; sliding friction force generated when an arc extinguishing chamber is connected or disconnected is reduced; an electric field is improved, cost is saved, and safety when the arc extinguishing chamber is connected or disconnected is improved; and the novel insulation pull rod gluing structure can be conveniently popularized and applied.

Description

(1) Technical field [0001] The invention relates to a novel bonding structure of insulating pull rods, which belongs to the technical field of insulating pull rods used inside high-voltage switches. (2) Background technology [0002] At this stage, the connection between the arc extinguishing chamber and the operating mechanism of the high-voltage GIS circuit breaker and the connection between the isolation knife switch and the grounding knife switch action have insulating pull rods. The traditional insulating pull rods include upper and lower joints, and upper and lower joints. There are shielding covers and insulating pull rods between the joints, and the arc bonding method is fixed by 0.1Kg epoxy resin adhesive. This design structure is difficult to process, the contact surface pressure is uneven, and there is no buffer zone It is easy to cause the joints and insulating rods to fall off, which will cause serious power outage accidents in substations and endanger personal ...
