Description
Technical field
The present invention relates to a kind of vacuum circuit breaker, particularly a kind of permanent magnetic vacuum breaker.
Background technology
The same with common AC circuit breaker, vacuum circuit breaker is also a kind of mechanical switch, i.e. by the mechanical movement of contact
Realize connection and the disjunction of circuit.Except that, the contact of vacuum circuit breaker is sealed in vacuum (referred to as vacuum interrupter
Or vacuum switch tube), the vacuum medium of utility excellence is dielectrically separated from and arc extinguishing means, thus has running voltage relatively
The advantages such as high, the arc time is short, contact electrical wear is few, contact surface non-oxidation.
The advantage of traditional spring vacuum circuit breaker of permanent magnetic vacuum breaker ratio is to realize vacuum circuit breaker
Remote control, it is not necessary to be manually controlled making chopper disconnect voluntarily, simple in construction, safer, but due to
Traditional spring vacuum circuit breaker of permanent magnetic vacuum breaker ratio is more prone to be disturbed by electric current, thus reduces permanent magnetism
The stability of vacuum circuit breaker and safety, the life-span also making permanent magnetic vacuum breaker is lower, and permanent magnet vacuum open circuit
The dismounting of device is the most cumbersome.
Summary of the invention
In view of the deficiency of background technology, problem to be solved by this invention is to provide a kind of simple in construction, and security performance is high,
Can solve the problem that the problem that permanent magnet mechanism damages because of current leakage, thus increase the permanent magnetic vacuum breaker in its service life.
To this end, the present invention uses following scheme to realize:
A kind of permanent magnetic vacuum breaker, including upper and lower insulation shell, is provided with vacuum interrupter, insulation in described upper insulation shell
Pull bar and dynamic and static contact, be provided with permanent magnet mechanism in described lower insulation shell, it is characterised in that: connecing of described upper and lower insulation shell
Being provided with electro-insulating rubber film at conjunction, described upper and lower insulation shell pressing electro-insulating rubber film, near absolutely inside described upper insulation shell
Being provided with piston seat at edge rubber membrane, described piston seat is provided with through hole, described insulated tension pole one end is connected with vacuum interrupter,
The other end is provided with piston, and described piston inserts in through hole, and the valve rod of described permanent magnet mechanism is fixed on the center of electro-insulating rubber film.
As preferably, described upper insulation shell inner wall section is rounded, and described upper insulation shell is close insulation rubber in bottom
Being provided with female thread at glued membrane, described piston seat is provided with the external screw thread matched with it, and described upper insulation shell is in the one of female thread
Side is additionally provided with convex annular edge, and described convex annular is along being provided with elastic washer, and described piston seat and upper insulation shell compress after being spirally connected
Elastic washer.
This programme have the beneficial effect that 1, vacuum interrupter be arranged at from permanent magnet mechanism different two insulation shell it
In, and middle using electro-insulating rubber film to isolate so that permanent magnet mechanism will not damage because of the leakage of electric current, and safety is more
High；2, sealant is formed between the cooperation of piston seat, piston and electro-insulating rubber film makes, when permanent magnet mechanism affects electro-insulating rubber film
Time, piston is pulled downwardly and pulls so that insulated tension pole moves down the purpose reaching open circuit；3, piston seat makes with upper insulation shell
Easily facilitating of vacuum circuit breaker is dismantled and maintenance, and elastic washer makes piston seat more firm with the sealing of upper insulation shell.
