Abstract

The invention discloses a disconnecting switch. The disconnecting switch comprises a base, supporting seats, insulating supporting columns and wire holders; the supporting seats are arranged on the two sides of the base; the number of the supporting seats, the insulating supporting columns and the wire holders is two separately; the supporting seats are fixedly connected with the base; the insulating supporting columns are mounted on the supporting seats; the insulating supporting columns are arranged at an angle of 50 degrees; the wiring holders are arranged on the insulating supporting columns; a stationary conductive plate and a movable conductive plate are arranged in the inner sides of the wiring holders separately; the stationary conductive plate is fixedly connected with the wiring holders, and the movable conductive plate is hinged with the wiring holders; a conductive contact finger is mounted at one end of the stationary conductive plate; a moving contact is arranged at one end of the movable conductive plate; and the moving contact is electrically connected with the conductive contact finger. The disconnecting switch is reliable in performance, simple in structure, flexile in installation ways, easy to maintain, and wide in the application range.

Description

technical field [0001] The invention relates to the technical field of power distribution equipment, in particular to an isolating switch. Background technique [0002] Isolating switch, that is, when in the off position, there is an insulation distance between the contacts that meets the specified requirements and an obvious disconnection mark; when in the close position, it can carry the current under normal circuit conditions and abnormal conditions (such as short circuit) within a specified time Switching equipment with low current, isolating switch (commonly known as "knife switch"), generally refers to a high-voltage isolating switch, that is, an isolating switch with a rated voltage of 1kV and above, usually referred to as an isolating switch, is the most used in high-voltage switching appliances A kind of electrical appliance, its working principle and structure are relatively simple, but due to the large amount of use and high reliability requirements, it has a grea...
