Description
Technical field
The present invention relates to a kind of breaker, and in particular to a kind of permanent magnetic drive breaker.
Background technology
Current killer switch species is various, and no matter its arc-chutes uses SF6 arc extinguishings, vacuum extinction or oil blast, by
In the reason for moving contact drives, its arc-chutes, which can not all be realized, is fully sealed isolation, so as to cause to run thing because of seal failure
Therefore.Arc quenching principle in current arc-chutes uses magnetic blow-out structure of contact terminal, due to being designed with blowout coil, causes contact dead volume
Increase, had both added precious metal usage amount and has again limited operating current.The folding of current dynamic and static contact is driven using spring
Dynamic, by telescopic spring execution, but as use time is elongated, spring can be tired, and elasticity is deteriorated or is broken, and shortens breaking
The service life of device causes accident.
The content of the invention
In view of the above-mentioned problems, the present invention takes one kind to control dynamic and static contact to open using homopolar-repulsion, the attracting principle of heteropole
Close, extend breaker service life, reduce the permanent magnetic drive breaker of accident rate.
To solve the above problems, the technical scheme that the present invention takes is：A kind of permanent magnetic drive breaker, including moving contact
Group, static contact group and arc-chutes, described static contact group include fixed contact pedestal and are secured to being located in arc-chutes of connection
Static contact；Described moving contact group includes the embedded moving contact magnetic conductor of movable contact block, movable contact block, electric with movable contact block
The permanent magnetism moving contact being located in arc-chutes of connection and for changing moving contact magnetic conductor magnetic so as to controlling permanent magnetism moving contact
With the driving permanent magnet of static contact folding；Described movable contact block neighboring is connected to fixed contact pedestal neighboring group by seal
Into sealed arc-chutes.
The magnetic conduction radome that permanent magnetism moving contact and static contact are surrounded in arc-chutes is fixed with movable contact block.
Permanent magnetism moving contact refers to the permanent magnet as moving contact；Moving contact magnetic conductor refers to close to permanent magnetism moving contact and to it
The magnetic conductor of power is acted, magnetic conduction radome refers to the magnetic conductor as radome.Wherein permanent magnetism moving contact can be relative to dynamic
Contact base is moved but both remain electrical connection, and electrical connection is not limited to ripple, flexible circuit conductor, the connection of flexible conductor piece etc.
Structure type.It is to be sealedly and fixedly connected between magnetic conduction radome and movable contact block, between static contact and fixed contact pedestal, is tightly connected
It is not limited to structure types such as welding, welding or bondings.It is vacuum or filling sulfur hexafluoride, transformer in described arc-chutes
The arc extinguishing dielectric such as oil.Magnetic conduction radome is introduced in arc-chutes, automatically between permanent magnetism moving contact, static contact and radome
Magnetic field is set up, magnetic blow-out current interruption function is realized.
Described moving contact magnetic conductor one end is close to permanent magnetism moving contact, and the other end stretches out movable contact block close to driving permanent magnetism
Body.Moving contact magnetic conductor one end is located in arc-chutes occurs opening and closing movement with static contact, and one end is close to driving permanent magnet.With drive
The change of dynamic permanent magnet polarity, moving contact magnetic conductor is geomagnetic into the magnet of corresponding polarity.
Described driving permanent magnet is rotating permanent magnet.Magnetic close to moving contact magnetic conductor is changed by rotating permanent magnet
Pole, the magnet to magnetropism is magnetized to by moving contact magnetic conductor, and permanent magnetism moving contact is controlled according to the attracting principle of homopolar-repulsion heteropole
Action, so as to control static contact, the folding of permanent magnetism moving contact.
A described rotary permanent-magnet outer periphery part is close to moving contact magnetic conductor, and remainder is surrounded by pole shoe；Pole shoe
Two ends are corresponding with magnetic conduction radome both sides.Described rotating permanent magnet, rotary permanent-magnet pole shoe and magnetic conduction shielding is covered with magnetic circuit company
Clearance system.Magnetic conduction radome transmits magnetic force, realizes that arc-chutes static state is totally-enclosed, it is therefore prevented that corrugated body or axle envelope ageing failure cause
Arc-chutes explosion accident.
Described driving permanent magnet is movable permanent magnet body.Magnetic close to moving contact magnetic conductor is become by movable permanent magnet structural reform
Pole, the magnet to magnetropism is magnetized to by moving contact magnetic conductor, and permanent magnetism moving contact is controlled according to the attracting principle of homopolar-repulsion heteropole
Action, so as to control static contact, the folding of permanent magnetism moving contact.Rotating permanent magnet or movable permanent magnet body are close to moving contact magnetic conductor
Magnetic pole change can be by executing agency's realization be connected with rotating permanent magnet or movable permanent magnet body, not office of described executing agency
Be limited to it is electronic, surge or the structure type such as pneumatic.
The set of permanent magnets that described movable permanent magnet body is connected through synonyms pole end by least two are into adjacent same of, each two
Name magnetic pole spacing is equal to the width of magnetic conduction radome.So that when ensureing that permanent magnetism moving contact is contacted with static contact, movable permanent magnet body
Two adjacent magnetic poles of the same name are corresponding with the both sides of magnetic conduction radome.Purpose is to make the magnetic and magnetic conduction on magnetic conduction radome
Body or dynamic and static contact are different, and movable permanent magnet body and magnetic conduction shielding are covered with communicated magnetic circuit relation, so that breaker opening and closing are produced
During electric arc, magnetic quenching effect is produced under electromagnetic force.
The present invention is simple in construction, and realize arc-chutes is fully sealed isolation, while utilizing homopolar-repulsion, the attracting original of heteropole
The dynamic and static contact folding of reason control, reliable in action, extension breaker service life, reduction accident rate.In addition, in arc-chutes
Interior introducing magnetic conduction radome, sets up magnetic field between permanent magnetism moving contact, magnetic conduction static contact and radome automatically, realizes magnetic blow-out current interruption
Function, with extensive use value.
