Abstract
The utility model discloses a release shunt mechanism for a circuit breaker, which comprises an iron core, a magnetic release coil and a small ampere coil; the magnetic release coil and the small ampere coil are respectively provided with two extending ends; one extending end of the magnetic release coil is connected with one extending end of the small ampere coil; the other extending end of the magnetic release coil is connected with the other extending end of the small ampere coil; one pair of extending ends of the two pair of connected extending ends of the small ampere coil and the magnetic release coil are connected with one end of a static contact blade and the other pair of connected extending ends are connected with a terminal external metal sheet. The structure is adopted; and one small ampere coil is connected and combined with the traditional big ampere magnetic release coil in parallel, because the breaking capacity of a small ampere circuit breaker is much higher than the breaking capacity of a big ampere circuit breaker, the breaking and shunting capacity of the traditional circuit breaker can be greatly improved through the structural design.
Description
Technical field
The utility model relates to a kind of circuit breaker, especially a kind of dropout diversion mechanism of circuit breaker.
Background technology
The breaking capacity of well-known circuit breaker, the breaking capacity of little ampere-circuit breaker is higher than big ampere-circuit breaker far away, DZ47-63 miniature circuit breaker for example, 6 amperes circuit breaker, Ics=6KA can easily pass by, and arriving 4.5KA, calculated well 32 amperes circuit breaker, even if it is passable that 63 amperes circuit breaker can reach 3KA, seldom can reach 6KA, its main cause is the circuit breaker below 6 amperes, its magnetic tripping coil interior lines strength is little, need the number of turns of pricking in limited space more, 6 amperes the 16-22 that can reach encloses, 2 amperes or 1 ampere then more, can reach the 30-50 circle, because electromagnetic capability is directly proportional with coil turn, so the magnetic release coil magnetic field power of little ampere-circuit breaker is far longer than the magnetic release coil magnetic field power of big ampere-circuit breaker, the iron core sucting speed of little ampere-circuit breaker is fast excessive ampere-circuit breaker far away also, therefore the iron core current limliting breaking capacity of little ampere-circuit breaker also is much higher than big ampere-circuit breaker, how making the breaking capacity of big ampere-circuit breaker also can reach the breaking capacity same with little ampere-circuit breaker, is a big problem of present everybody research.
Summary of the invention
At the deficiencies in the prior art, the utility model provide a kind of simple in structure, cost is lower and the dropout diversion mechanism of the circuit breaker of disjunction shunting ability superelevation.
For achieving the above object, the utility model provides a kind of dropout diversion mechanism of circuit breaker, include iron core, magnetic tripping coil, little ampere coil, described magnetic tripping coil and little ampere coil are respectively equipped with two elongated ends, one elongated end of magnetic tripping coil is connected with an elongated end of little ampere coil, and another elongated end of magnetic tripping coil is connected with another elongated end of little ampere coil.
The beneficial effects of the utility model are: with the magnetic tripping coil in parallel combination of a little ampere coil with former big ampere, because the breaking capacity of little ampere-circuit breaker is higher than big ampere-circuit breaker far away, so such structure setting, can significantly improve the disjunction shunting ability of former circuit breaker, and add a little ampere coil, production cost is lower, helps using and popularization.
The utility model can further be set to described magnetic tripping coil, little ampere coil all is set on the iron core, and described magnetic tripping coil is arranged on little ampere coil inboard.
The utility model can further be set to described magnetic tripping coil, little ampere coil all is set on the iron core, and described little ampere coil is arranged on magnetic tripping coil inboard.
The utility model can further be set to described magnetic tripping coil, little ampere coil all is set on the iron core, and described magnetic tripping coil and little ampere coil are separately positioned on the two ends of iron core.
The utility model also can further be set to described little ampere coil and be connected with an end of static contact with a end in two elongated ends that the magnetic tripping coil is connected together, and another elongated end that is connected together and binding post sheet metal outward are connected.
The utility model also can further be set to described iron core and also be provided with the iron core frame outward, and iron core is located in the iron core frame, and described magnetic tripping coil and little ampere coil all are arranged in the iron core frame.
