Abstract
The invention relates to high and low voltage switch accessories, in particular to an operating mechanism, which belongs to the technical field of electric appliances. The invention discloses a permanent magnetic operating mechanism which has a manual closing operation function and is also provided with an auxiliary electromagnetic loop. According to the technical scheme provided by the invention, a mechanism core of the permanent magnetic operating mechanism is assembled in a guide sleeve cavity, and the problem of manual closing mechanical dead point is solved by over-travel setting of closing operation, so that the manual closing operation can be as reliable as electric closing operation. A guide sleeve is doubled as a part of the auxiliary electromagnetic loop, so that the mechanism has the advantages of low operation power consumption, small size and less usage of permanent magnet.
Description
Technical field
The present invention relates to high and low pressure vaccum electric apparatus switch fitting, particularly operating mechanism, belong to technical field of electric appliances.
Background technology
In recent years, permanent-magnet manipulating mechanism is highly reliable with it, long-life, the advantage such as easy to control cause in the industry common concern and developed rapidly, but the puzzlement permanent magnet mechanism continues the technical barrier in development and expanded application field, both guaranteed the technical advantage that permanent magnet mechanism is highly reliable, can realize again the manually reliable closing operation of spring energy-storage, not be resolved always.
Summary of the invention
The object of the invention is to, a kind of permanent-magnet manipulating mechanism that had not only possessed the closing by hand operating function but also be provided with auxiliary electromagnetic circuit is provided.
For realizing purpose of the present invention, in the technology of the present invention solution, mechanism's core body is assemblied in the cavity of guide pin bushing, and the outer yoke in mechanism's core body and guide pin bushing matched in clearance.Wherein, described guide pin bushing is the ladder barrel shape, and is provided with ring plain, and the top of guide pin bushing is double does auxiliary yoke, and consists of the part of auxiliary electromagnetic circuit with the periphery of moving iron core.The bottom of the outer yoke of described mechanism core body is provided with annular boss axially corresponding with ring plain.In this mechanism closing by hand, electric switch-on operation transient process, the interface of annular boss axially is being positioned between gap L.When stable state kept behind the closing by hand operation of this mechanism, the electric switch-on EO, ring plain overlapped with the annular boss interface.
Employing the present invention proposes and is configured in the permanent-magnet manipulating mechanism on the high and low pressure switch, can guarantee mechanical dead point can not occur in the closing by hand operating process.The design of auxiliary electromagnetic circuit has improved the distribution of suction electromagnetic field, so that the permanent magnet consumption is few, the mechanism body volume is little, and the electric switch-on operation is low in energy consumption, and can effectively guarantee the electromagnetism cleaning of adhesive working face.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is the structure cutaway view of this mechanism.
Fig. 2 is the cutaway view of this mechanism combined floodgate stable state hold mode.
Embodiment
Describe details and the closing by hand operation element principle of the mechanism that proposes according to the present invention in detail below in conjunction with accompanying drawing.
Contrast Fig. 1 can find out with reference to Fig. 2, guide pin bushing 2 is the ladder barrel shape, mechanism's core body is assemblied in the cavity 1 of guide pin bushing 2, the interface of the annular boss 6 of the outer yoke 3 in ring plain 5 and the mechanism core body is axially corresponding, the periphery 4 of moving iron core and the top of guide pin bushing 2 is radially corresponding, the part of formation auxiliary electromagnetic circuit.
Contrasting Fig. 2 can find out, when the combined floodgate stable state kept, the interface of annular boss 6 overlapped with ring plain 5.
This mechanism is configured on the high and low pressure switch, its closing by hand operation principle is: external cam pendulum compressing closing by hand connecting lever, make the moving guide rod compression contacts overshoot of vacuum interrupter greater than setting, and its plussage less than gap L after free slippage, then mechanism's core body moves upward and keeps by ring plain 4 stable states location.
In addition to the implementation, the present invention can also have other execution modes, and all employings are equal to the technical scheme of alternative or equivalent transformation form, all in the scope of protection of present invention.
