Abstract

The invention discloses a manual brake separating mechanism for a high voltage switch, which comprises brake separating crankarm which is fixed on a driving spindle, a brake separating cam which is rotatablely arranged on the shell through a hinge pin, a handle which is used to drive the brake separating cam to rotate, and a torsional spring which is used to provide the brake separating cam with resetting elastic force, the handle drives the brake separating cam to rotate, the brake separating cam pushes the brake separating crankarm to carry out motion during the process of rotation thereof so as to drive the driving spindle to rotate, thereby realizing the manual brake separating operation. The invention has the advantages of simple structure, fewer parts and better reliability.

Description

technical field [0001] The invention belongs to the technical field of high-voltage switch structure design, and in particular relates to a manual opening mechanism for a high-voltage switch. Background technique [0002] The high-voltage vacuum permanent magnet circuit breaker is used in the power system. As a control and protection switch of high-voltage electrical equipment, it is required to be able to perform both electric opening and closing operations and manual opening and closing operations. At present, its electric operation structure has become mature, while the manual opening structure is varied and has its own characteristics. Basically, there are some problems as follows: First, the operating parts to realize the manual opening function are complicated and not many, which loses the advantages of simple structure and few failure points of the permanent magnet drive mechanism; , Electric operation and manual operation interfere with each other.
