Novel double-column vertical open type outdoor high-voltage AC disconnecting switch

Abstract

The present invention discloses a novel double-column vertical open type outdoor high-voltage AC disconnecting switch. The switch comprises a bottom frame, a first pillar insulator, a second pillar insulator, a conductive loop, a static side contact socket, and a movable side contact socket. The conductive loop comprises a conductive blade, and the conductive blade is provided with a self-lockingdevice; a latching device is arranged above the second pillar insulator and on one side of the static side contact socket away from the movable side contact socket, and the side surface of the latching device is provided with a concave latching groove; the position of the concave latching groove is engaged with a hook body; the hook body is internally provided with a stainless steel leaf spring; the conductive loop adopts a fully enclosed structure; all conductors of the conductive loop are enclosed inside the insulating material; and a static contact, a static side wiring board and a movableside wiring board are installed in the insulator. According to the technical scheme of the present invention, the stainless steel leaf spring is arranged in the hook body, so that influence on the rotation sensitivity of the hook body caused by the exposure of the stainless steel leaf spring to the wind and rain can be avoided; and by using the fully enclosed structure of the conductive loop, short circuits caused by birds and foreign objects can be avoided.

Description

technical field [0001] The invention belongs to the technical field of switching appliances in substation electrical systems, in particular to a high-voltage isolating switch, which is an indispensable electrical device in the substation electrical system, in particular to a novel double-column vertical open outdoor high-voltage AC isolating switch. Background technique [0002] At present, the isolating switch is the most widely used electrical equipment in the high-voltage switch electrical equipment, and it plays a vital role in the transmission and distribution circuit, especially the double-column vertical open outdoor column-mounted high-voltage AC isolating switch is used in rural power grids. particularly broad. However, with the continuous reflection of the operation and maintenance personnel of the rural power grid in recent years, the operating effect of the existing isolating switch is not very satisfactory. Such as: galvanic corrosion and poor contact lead to h...

AI Technical Summary

Problems solved by technology

Such as: galvanic corrosion and poor contact lead to heating; rust leads to stagnation; faults such as self-opening of the isolation switch and short circuit caused by flying birds and foreign objects have brought great safety hazards to rural electricity consumption, and also caused great harm to operation and maintenance personnel. troubled
