The problem to be solved in the present invention is to provide a kind of circuit breaker, especially a kind of high pressure resistant, and the small-sized multibreak circuit breaker that contact synchronism is high.
For solving the problems of the technologies described above, the present invention includes contact system, arc quenching system, operating mechanism, link gear, release, shell, handle, described arc quenching system comprises arc control device and is arranged at the arc extinguishing grid pieces in arc control device, described contact system comprises moving contact and fixed contact, described operating mechanism is linked by link gear and moving contact, two arc quenching systems are provided with in described case for circuit breaker housing, be respectively the first arc quenching system and the second arc quenching system, first arc control device of described first arc quenching system and the second arc control device of the second arc quenching system are disposed adjacent, and be provided with the dividing plate cut off by electromagnetism between two arc control device between the first arc control device and the second arc control device, described housing is positioned at the first arc control device side and is installed with the first fixed contact, described second arc control device side and be provided with the second fixed contact with the first fixed contact level and lengthwise position corresponding section, described moving contact comprises the first moving contact of setting corresponding with the position of the first fixed contact and the second moving contact with the corresponding setting in the position of the second fixed contact respectively, described first moving contact and the second moving contact are connected in series.
After have employed said structure, owing to have employed two arc quenching systems, and the arc control device electric isolution in these two arc quenching systems is arranged, corresponding with two arc quenching systems is be in relative position, can two contact systems of opening and closing together, two contact systems are connected formation loop jointly, when at breaker closing or can be disconnected by such arranging, because the larger voltage of instantaneous generation is simultaneously through two arc quenching systems, make miniature circuit breaker can bear larger instantaneous voltage when other conditions are consistent.
As a further improvement on the present invention, described first moving contact and the second moving contact are integrated setting, and the U-shaped moving contact block of interconnected formation between the first moving contact and the second moving contact, described U-shaped moving contact block comprises two ends contact end and one end link, the link of described U-shaped moving contact block is flexibly connected with link gear, and the link of U-shaped moving contact block can rotate around the junction circumference with link gear.
After have employed said structure, after two moving contacts are wholely set, not only achieve the series connection between moving contact, and when moving contact closes, ensure that certain synchronism, and the setting of U-shaped moving contact block facilitate especially install and shaping.
As a further improvement on the present invention, described link gear comprises the tripping be connected with handle, and the linkage board be arranged at below tripping, described linkage board is provided with hinged axial trough, the jointed shaft suitable with jointed shaft groove shape is provided with in described hinged axial trough, described U-shaped moving contact block is provided with axis hole near jointed shaft place, and described jointed shaft is articulated with in axis hole.Described U-shaped moving contact block is positioned at the both sides in its direction of motion, be arranged with two shapes and the consistent stopper slot of size, described linkage board is equipped with guide vane end stop near two stopper slot places, and the air line distance between relative two faces of described two guide vane end stops is greater than the air line distance of two stopper slot groove centers.
After have employed said structure, owing to finding in implementation process, moving contact its moving surface in motion process is difficult on same perpendicular, and fixed contact also exists corresponding problem, cannot accomplish real parallel, always there is certain error.
So the link taking moving contact in above-mentioned technique effect can carry out the technical scheme of freely rotating, this technical scheme not only implements more for convenience, and technique effect is also better.Because U-shaped moving contact block can around junction oneself's axial rotation, when one end end face of U-shaped moving contact block contacts with fixed contact, and the other end due to equipment error do not contact time, U-shaped moving contact block will self-axial rotation, to the deflection of non-contact jaw, make two ends all obtain fast with contact fully.The setting of guide vane end stop and stopper slot then ensure that the restriction of moving contact initial condition and motion state restriction, avoids contact to start to offset poised state too much.
