Circuit breaker is generally used for disjunction high-tension line, when disjunction high-tension line, easily produces electric arc, and electric arc not only can cause to puncture and cause purpose of breaker failure, and electric arc can produce high temperature and burn breaker assembly, even causes fire.Therefore conventionally in circuit breaker, be all provided with arc-control device or structure, common arc quenching method is mainly to fill insulation oils or insulating gas, or the contact of circuit breaker is placed in to vacuum environment, the mode that can simultaneously open circuit by multiple spot in addition reduces the generation intensity of electric arc, thereby reduces the harm of electric arc.
Summary of the invention
The object of the present invention is to provide a kind of synchronous multistage circuit breaker, simple in structure, low cost of manufacture and have the function that multiple spot opens circuit simultaneously and fills insulation oils or insulating gas arc extinguishing concurrently, thus the arc extinguishing ability that improves circuit breaker is the ability of disjunction high-voltage circuit.
To achieve these goals, the technical scheme that the present invention proposes is:
A kind of synchronous multistage circuit breaker, comprise shell, sliding bar, partition wall, leading-out terminal, contact, contiguous block, bonding conductor, described partition wall is divided into a plurality of cavitys by described shell, described sliding bar be movably set in described shell and described sliding bar through cavity described in each, described in each, in cavity, be provided with a pair of contact and the contiguous block that is connected a pair of described contact, described contiguous block is fixedly arranged on described sliding bar, described bonding conductor is together in series a plurality of described contacts, after series connection, the described contact at two ends is drawn and place in circuit by described leading-out terminal, described in each, in cavity, be all filled with insulation oils or insulating gas.
As the further improved synchronous multistage circuit breaker of the present invention, described sliding bar be provided with spacing preiection one and and spacing preiection two, described spacing preiection one is used to indicate connection circuit, described spacing preiection two is used to indicate a minute deenergizing.
As the further improved synchronous multistage circuit breaker of the present invention, described contact is arc-shaped flaky structure, and described in each, the arc convex face of a pair of described contact in cavity arranges in opposite directions.
As the further improved synchronous multistage circuit breaker of the present invention, described leading-out terminal comprises leading-out terminal one, leading-out terminal two, described contact comprises contact one, contact two, contact three, contact four, described contiguous block comprises contiguous block one, contiguous block two, described cavity comprises cavity one and cavity two, described contact one and described contact two are arranged in described cavity one and by described contiguous block one connection, described contact three and described contact four are arranged in described cavity two and by described contiguous block two connections, described bonding conductor connects described contact two and described contact three, described contact one connects described leading-out terminal one, described contact four connects described leading-out terminal two.
Synchronous multistage circuit breaker provided by the present invention, simple in structure, low cost of manufacture and have the function that multiple spot opens circuit simultaneously and fills insulation oils or insulating gas arc extinguishing concurrently, thus the arc extinguishing ability that improves circuit breaker is the ability of disjunction high-voltage circuit.
