Description
Technical field
The present invention relates to electrical device technical field, especially relate to a kind of double direct acting switch, concrete
Say it is that a kind of rectilinear structure using permanent-magnet manipulating mechanism switchs.
Background technology
On-load voltage regulating switch structure of the prior art is complicated, and volume is relatively big, relatively costly, usually rotating cage
Structure, drive mechanism is usually motor and drives main shaft to rotate, and changes appearance time length, changes volume flow rate degree slowly, changes appearance
Time be easily generated electric arc, life-time service causes poor contact of contacts, and cooling oil impurity increases, and insulation declines, no
Preferably at 10kV distribution occasion spread.
And non-excitation pressure adjustment (No-load changer) though switch cost relatively low owing to there are some congenital defects:
One is must to operate under transformator is without excited state, needs certain power off time to be adjusted, interference
Normal production；Two is manual operation, adjusts number of times restricted, is only capable of making interim or seasonal adjustment,
Can not often carry out, it is impossible to control the voltage pulsation caused by electricity peak valley change every day, the company simultaneously powered
Continuous property and reliability also cannot well be ensured.
Existing patent (number of patent application: 201120180886.4) provides a kind of overall structure simple, transmission
Parts are few, and conversion speed is fast, and reliable in action energy-conservation permanent magnetic mechanism switch well solve above-mentioned asking
Topic.But due to shunting switch system disc-shaped structure, for improving product dielectric level, contact pitch needs to strengthen,
For ensureing to insulate, volume of switch to increase, and cost increases more；And Transformer Winding lead-in wire need to be in plate-like
Switch wiring around, inefficient.
Existing patent (number of patent application: 201310492317.7) provides a kind of quick two-way three condition switching
Electric power switch unit, switching time is short, volume is little, contact reliable advantage, but drive disk assembly is more complicated,
Contact installing requires that high, to provide contact force structure is complicated, manufacturing cost is higher.
Summary of the invention
The invention aims to solve the deficiency of above-mentioned technical problem, it is provided that a kind of direct acting type, large opening,
Simple in construction, contact double direct acting reliable, lower-cost switch, solve the problems referred to above.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of double direct acting switch, including power set, pedestal and on described pedestal left and right slidably set
The direct acting part put, described direct acting part is fixedly installed at least one moved end；Described power set drive described
Direct acting part horizontally slips on described pedestal；
Each described moved end all includes excess of stroke spring, positioning and guiding seat and two, the left and right moved end contact being oppositely arranged,
Described moved end contact includes the small end of column and the big end of dish dress, and described positioning and guiding seat is provided with two, left and right
Pilot hole；The small end of two described moved end contacts passes the pilot hole of respective side respectively, at described pilot hole
The most slidably arranging, the outside diameter of described moved end contact is more than described pilot hole；Described excess of stroke spring withstands on two
Between the contact of individual moved end；
Each described moved end is correspondingly arranged two the quiet ends in left and right, and each described moved end is corresponding arranges left and right two
Individual quiet end constitutes a sets of contacts；Described quiet end is fixed on described pedestal, and described moved end is positioned at corresponding
Two quiet ends between, when described moved end horizontally slips with described direct acting part, the small end of described moved end contact
Top withstands on the quiet end contact of described quiet end.
Described power set are permanent-magnet manipulating mechanism, and described direct acting part is provided with driving hole, described permanent magnetic operating
Mechanism is connected with described direct acting part by described driving hole.
Leave gap between small end and the described pilot hole of described moved end contact, and described moved end contact is little
End top is convex surface, and the contact of described quiet end is plane or concave surface.
The corresponding described quiet end contact of described moved end contact is point-blank.
Being fixedly installed three described moved ends on described direct acting part, described sets of contacts has three groups.
The present invention and existing patent [number of patent application: 201310492317.7] difference are: 1, existing
Patent is had to lean on wedge-shaped slot to coordinate clamping wedge tooth to realize the reliable purpose of contact；This patent leans on excess of stroke spring
Realize increasing contact pressure, contact reliable purpose；2, the two ends of existing patent traveling electrode are respectively provided with one
Individual main contacts, the fixed-node corresponding with main contacts also has two, must be with when the two fixed-node is arranged
Traveling electrode is on 1 straight line, it is impossible to have deviation, otherwise misaligns during contact between possible contact, arranges
Difficulty is higher；This patent is two movable contacts, and moved end contact is arranged in a hole of guide holder and has certain
Activity remaining, and movable contact is set to sphere, and stationary contact is fixed on quiet end and is set to plane,
During moved end contact can be looked for automatically, contact is good；3, existing patent is by driving shaft core, ordering about transverse guide
Just can be transmitted to traveling electrode, but also need the auxiliary member fixing these parts, structure is complicated；This patent
By driving direct acting part directly to drive connected moved end, the most reliably；4, existing patent by spring mechanism,
The modes such as contact coil tension spring highlight a fast feature of conversion speed, meet the purpose being switched fast power supply；
This patent preferably drives many group contacts to change by permanent magnet mechanism simultaneously, meets multi-tap transformer lead and divides
Connect the purpose of mode fast and reliable conversion；5, existing patent is to increase clearance between open contacts, improves dielectric level,
Housing and overall volume need to increase；What the moved end of this patent, quiet end used be arranged in parallel, and integrated model is
Straight line flat structure, is not required to increase volume and i.e. can reach the purpose that clearance between open contacts increases, improves dielectric level.
Beneficial effects of the present invention is as follows.
Overall structure of the present invention is strip, has a normally opened and normally-closed contact simultaneously, and moved end, quiet end are the most only
Vertical, can easily realize contact large opening, transmission of the present invention is directly reliably, conversion speed is fast, volume is little,
Low cost, is suitable for the Integration Design of small space and complete set of equipments, is particularly suitable for being built in oil immersed type and becomes
Use as shunting switch inside depressor.
