Abstract
The utility model relates to a plastic housing type electrically-operated mechanism for a breaker, comprising a housing, a drive motor and a switch, wherein the drive motor drives a transmission mechanism, and the drive motor is an AC synchronization motor. The plastic housing type electrically-operated mechanism for a breaker requires a smaller reduction ratio under a same output rotating speed, uses an AC synchronous motor as a drive element, is smaller and more exquisite in structure and lower in manufacture cost.
Description
Technical field
The utility model relates to the application of autosynchronous motor in the motor-operating mechanism of moulded case circuit breaker; Focus on taking the lead in the motor-operating mechanism of moulded case circuit breaker, adopting autosynchronous motor as driving element, belong to low tension switch attachment technique field.
Background technology
In professional and complete low voltage electrical apparatus industry, driver part adopts A.C. series motor and permanent magnet direct current motor and electromagnet coil mostly in the motor-operating mechanism of existing moulded case circuit breaker.The utility model belongs to and in the motor-operating mechanism of moulded case circuit breaker, has adopted novel motor as driving element.
It is big that A.C. series motor has a starting current, braking difficulty, high these shortcomings of rotating speed.
Permanent magnet direct current motor be owing to will adopt switching power circuit, therefore has under the situation of numerous advantages also to cause the cost problem of higher.
Electromagnet coil has that starting current is big, and impact endurance test shock is big, shortcomings such as outage difficulty.
Adopting the motor-operating mechanism of the utility model on the basis of the motor-operating mechanism advantage with most employing permanent magnet direct current motor, to have good and economic again simultaneously, is the very high product of a cost performance.
The utility model content
The utility model purpose is to provide a kind of novel driving element to be applied to the motor-operating mechanism of moulded case circuit breaker for the deficiency that overcomes prior art.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of motor-operating mechanism of moulded case circuit breaker, include housing, drive motors and switch, and drive motor drives transmission mechanism, said drive motors are ac synchronous motor.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
Because autosynchronous motor has the low advantage of rotating speed with respect to A.C. series motor and permanent magnet direct current motor; The speed reducing ratio that under identical output speed, requires is just little; The employing autosynchronous motor can be smaller and more exquisite as the motor-operating mechanism structure of the moulded case circuit breaker of driving element, and manufacturing cost also reduces accordingly.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the structural representation of the utility model;
Wherein: 1, housing; 2, switch; 3, motor.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The utility model shown in accompanying drawing 1 is described because autosynchronous motor has the low advantage of rotating speed with respect to A.C. series motor and permanent magnet direct current motor; The speed reducing ratio that under identical output speed, requires is just little; The employing autosynchronous motor can be smaller and more exquisite as the motor-operating mechanism structure of the moulded case circuit breaker of driving element, and manufacturing cost also reduces accordingly.
Below only be the concrete exemplary applications of the utility model, the protection range of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
