Abstract

The invention discloses an isolating knife, comprising an insulating seat fixedly mounted on an isolation shaft. The insulating seat is provided with a connecting plate in a radial direction, and opposite sides of the connecting plate are respectively connected with an isolating blade. The two isolating blades are connected by a compression spring pin. Compression springs are disposed between twoends of the compression spring pin and respective adjacent isolating blades. One end of the isolating blade, connected with the connecting plate, is fixedly connected with an isolation flexible connection. The isolation flexible connection is provided with an arc structure for bypassing the insulating seat. A purpose of the isolation knife is to provide an isolating knife that is reliable in performance, compact in structure, and convenient in installation.

Description

technical field [0001] The invention relates to an isolation knife for a high-voltage switch cabinet, in particular to an isolation knife used for composite insulation of an AC distribution network using an air insulating medium. Background technique [0002] With the economic development of the society and the continuous acceleration of the urbanization process, more requirements are put forward for the construction of distribution network, and more and more attention is paid to the area occupied, safety and environmental protection, stability and maintenance-free. In order to meet the above requirements, various switchgears are constantly emerging. Especially with air or N 2 Switch cabinets with some environmentally friendly materials as insulating media have become a future development trend. This also puts forward new requirements for the structure of each component in the switchgear. The previous isolating knife cannot meet the requirements of voltage resistance perfo...
