Isolating switch flat-clamping type conductive knife switch and switching-on and switching-off method thereof

Abstract

The invention relates to an isolating switch flat-clamping type conductive knife switch and a switching-on and switching-off method thereof. The conductive knife switch is characterized by comprisingan insulator unit which comprises an operating insulator positioned in the middle and post insulators positioned on two outer sides, the top ends of the two post insulators are each provided with a static contact, and the top end of the operating insulator is provided with a conductive knife switch matched with the static contact. The conductor structure is simple in overall principle, good in heat dissipation performance and high in through-current capability, during closing, the conductive tube bidirectionally clamps the static contact in the plane direction, resistance generated during opening and closing due to the fact that the static contact is directly beaten in is avoided, the knife return phenomenon is avoided, and the operation life performance is excellent; and when the static contact is clamped by the conductive knife switch, the staggered distance of the two conductive tubes is large, the conductive knife switch cannot be clamped by the static contact in an icing state, the two conductive tubes can extrude an ice layer to break the ice layer in the process of clamping the static contact, and the structure is high in ice breaking capacity.

Description

technical field [0001] The invention relates to the technical field of isolating switches, in particular to a flat clip-type conductive switch blade of an isolating switch and an opening and closing method thereof. Background technique [0002] At present, the three-column horizontal double-fracture structure isolating switch is composed of a base, a post insulator, an operating insulator, a main conductive part, a transmission system, and a grounding switch; the three-column horizontal rotary type that meets product requirements can be selected according to the form of conductive movement. The structure has flip type, flat clip type and snap-on type. The mainstream structure of the conductor is the flip type. When the product is in the opening position, the rotating shaft of the isolating switch operating mechanism rotates horizontally, and the transmission device of the base is driven by the vertical tube to make the middle operating insulator Rotate, the upper conductive ...
