Background technology
It is Microsecond grade IGBT used by DC current is cut-off in flexible direct current extra-high voltage converter valve transmission system at present
Carry out quick-speed turning on-off electric current.Because direct current does not have zero passage can not be cut-off using existing AC vacuum circuit-breaker, but by more
The IGBT switch on-state loss of a IGBT series connection is very big, excessive on-state loss also add cooling system infrastructure cost and to
Uncertain security risk is carried out in performance stabilized zone.
The content of the invention
For the problems of the prior art, the present invention provides a kind of extra-high voltage direct-current permanent magnetism mixing breaker, can solve
The mechanical chopper drop-out current time of certainly current existing spring mechanism and hydraulic mechanism or permanent magnet mechanism is within a few tens of milliseconds
It cannot meet the problem of direct current is cut-off.
To reach above-mentioned purpose, technical solution provided by the invention is：
A kind of extra-high voltage direct-current permanent magnetism mixing breaker, including it is electrical insulation board, upper copper bar, insulation column, vacuum tube, true
Blank pipe contact, be flexible coupling, pull rod, permanent magnet, dynamic iron core, armature, separating brake under contact pull rod, touch spring, insulator, insulator
Coil, eddy-current disc, closing coil, winding wiring terminal, metal base plate, capacitance and capacitive energy storage room, it is characterised in that：Described
Permanent magnet, dynamic iron core, armature, switching winding, eddy-current disc, closing coil form permanent magnet mechanism；The insulation column shares phase
Same four, which is vertically consolidated in metal base plate corner, and the top of four insulation columns is vertically consolidated with electrician
Insulation board；The moved end of the vacuum tube be equipped be flexible coupling, lower copper bar and insulator；Contact bullet is equipped with the insulator
Spring, for ensureing that main contact bounces；Pull rod is connected in dynamic iron core under the insulator, which loads exhausted
Vacuum tube in edge frame, coil flux induce opposing magnetic field in eddy-current disc, form repulsion and are delivered to by insulator pull rod
Vacuum tube moving contact completes on/off switch action.Eddy-current disc force direction, coaxially without connecting lever lever, drives with the moving contact direction of motion
Dynamic mechanics of system transmission function simple and stable, actuation time dispersion degree are adapted to accurately control less than positive and negative 0.2ms.Using energy storage electricity
Hold the electric discharge of pairing switching winding, driving force intensity is directly proportional to capacitive energy storage, and the exportable larger electric current of capacitive energy storage mode makes
On/off switch can be completed between 3ms by obtaining breaker.The creepage distance of this dc circuit breaker is all designed as sealing with electric clearance
Formula is completely different to be ensured of by space with AC vacuum circuit-breaker creepage distance electric clearance used in present electric power.
Using technical solution provided by the invention, compared with prior art, have the advantages that：
(1) a kind of extra-high voltage direct-current permanent magnetism mixing breaker of the invention, is designed so that this direct current sealing by fixed sealing type
The volume of breaker has the characteristics that small and light weight less than the half of the existing AC circuit breaker in market, and due to structure
It is simpler, compact, make the product relatively reliable.
(2) a kind of extra-high voltage direct-current permanent magnetism mixing breaker of the invention, simple in structure, of low cost, operation is easy, just
In promoting the use of.
