Background technology
Outdoor high-pressure permanent magnetism vacuum circuit breaker is as the key equipment of control and protection electric power netting safe running; its major function is the moving contact knee-action that relies in the permanent-magnet manipulating mechanism drive vacuum interrupter of installing in the circuit breaker; make the fixed contact of the moving contact of lower end in the vacuum interrupter and upper end cut-off or close and close, thereby realize disconnection and the closure of electric current in the operation of power networks.Circuit breaker has the very large electric current of load and very high voltage between the dynamic and static contact of arc control device when operation of power networks, particularly when electrical network outlet fault, suffer lightning impulse such as line short, circuit, at this moment the transient current in the circuit will be above the rated current several times.This just require circuit breaker the utmost point in the short time (18～30ms), disconnect with high speed, thereby the protection power grid security.
Vacuum circuit-breaker on the present outdoor column, for development and the requirement that adapts to intelligent power network, its actuating part all adopts permanent magnet mechanism as power source.Although that permanent magnet mechanism has is energy-conservation, low consumption, high life, the plurality of advantages such as non-maintaining, be widely applied, but the high voltage permanent magnet vacuum circuit breaker on outdoor post of existing structure still exists manual minute brake structure comparatively loaded down with trivial details, and the weak point more, that operational stroke is larger takes up room.
Summary of the invention
The purpose of this utility model provide a kind of manual brake separating structure comparatively rationally, less high voltage permanent magnet vacuum circuit breaker on outdoor post takes up room.
The technical scheme that realizes the utility model purpose is: a kind of high voltage permanent magnet vacuum circuit breaker on outdoor post comprises the housing that is provided with the magneto powder operation device and three poles that are arranged on the housing; Described magneto powder operation device comprises main shaft, STATEMENT OF FEDERALLY SPONSORED and permanent mechanism driving mechanism, and this permanent mechanism driving mechanism drives main shaft by STATEMENT OF FEDERALLY SPONSORED and moves back and forth; Described permanent magnet type drive mechanism comprises shell and drive rod; Be provided with the location-plate of a plurality of protrusions in the described housing; Drive rod and the main shaft of described permanent magnet type drive mechanism be arranged in parallel, and its shell comprises tubular matrix, antetheca and rear wall; Described location-plate is positioned at the both sides, front and back of permanent magnet type drive mechanism, and is fixedly linked by antetheca or the rear wall of bolt respectively at corresponding permanent magnet type drive mechanism shell.
In the technique scheme, the basic configuration of described location-plate is L shaped.
In the technique scheme, antetheca and the rear wall of described permanent magnet type drive mechanism shell are provided with screw.
In the technique scheme, described STATEMENT OF FEDERALLY SPONSORED is a lever, and its middle-end is rotated and is arranged on the housing, and one end and drive rod are rotationally connected, and its other end and main shaft are rotationally connected.
The structure of manual brake separating mechanism and position arrange rationally in the utility model, and it is less to take up room, and have preferably reliability.
