Abstract

An isolation and grounding interconnection device of a pole-mounted intelligent composite apparatus comprises a line input guide plate, a line output guide plate and a grounding guide plate, which are connected to a line input connector, a line output connector and one side surface of a box body respectively. The line output guide plate and the grounding guide plate are provided with a first through hole and a second through hole; a conducting rod is arranged between the line input guide plate and the grounding guide plate and passes through the first through hole; the upper end of the conducting rod is provided with a conductive contact ring; an insulating rod is arranged under the line output guide plate and passes through the second through hole; a grounding contact ring connecting with the conducting rod and the insulating rod is arranged between the line output guide plate and the grounding guide plate; and the lower end of the insulating rod is provided with a power mechanism for driving the insulating rod and the conducting rod to move up and down. The isolation and grounding interconnection device can simultaneously realize disconnection of the pole-mounted intelligent composite apparatus and grounding of a user side, thereby facilitating operation of maintainers, and ensuring personal safety of the maintainers.

Description

technical field [0001] The invention relates to the technical field of electrical control equipment, and more specifically refers to an intelligent combined electrical isolation and grounding interconnection device on a pole. Background technique [0002] Outdoor pole-mounted vacuum circuit breakers are often used in rural power grids and urban power grid systems for switching and closing load currents, overload currents and short-circuit currents. The vacuum circuit breaker on the outdoor column mainly includes an upper insulation cylinder, a lower insulation cylinder, a vacuum interrupter, an operating transmission mechanism and a box body. The vacuum interrupter is set in the upper insulation cylinder, and the operation transmission mechanism is installed in the box. The circuit breaker contacts are arranged in the arc chamber, the incoming line connector is arranged in the upper end surface of the upper insulating cylinder, and the outgoing line connector is arranged on ...
