Abstract
The utility model relates to a circuit breaker, in particular to a circuit breaker self-propelling self-locking structure that is mainly applied to conversion between action states in the circuit breaker. According to the technical solution provided by the utility model, a bracket is arranged on a lower side of an auxiliary contact. A main shaft is arranged on a lower side of the bracket. The main shaft is provided with a rotatable suspension arm, a lower end of which is hinge jointed with a middle part of a main contact, characterized in that a rotating lever is hinge jointed by a shaft on the bracket. The upper end of the rotating lever contacts a handspike of the auxiliary contact and the lower one contact the upper end of the suspension arm; when the main contact is closed or opened; the suspension arm is driven to rotate to drive the rotating lever to move; then the rotating lever feeds the closed and opened interlock of the main contact to the auxiliary contact. The utility model can be applied to conversion of the auxiliary contact of the circuit breaker to realize the interlock conversion between the main contact state and the auxiliary contact state by a rotational structure. The structure is simple and reliable with great technology.
Description
Technical field
The utility model relates to a kind of circuit breaker, refers in particular to a kind of self-push self-pull type structure for breaker, is mainly used in the conversion that realizes in the circuit breaker between the operate condition.
Background technology
In the prior art, the organization plan that is used for two positions of circuit breaker interlocking switching motion has a lot, but most more complicated, the structure of this complexity can cause dispersiveness, the unreliability of quality, even the increase of cost.In certain structures, adopt spring structure spare to reset and the location, but in use tend to come off, thereby reduced reliability of products.
Summary of the invention
The purpose of this utility model is a kind of self-push self-pull type structure for breaker of design, with simplified structure, improves reliability of products.
The technical scheme that provides according to the utility model, support is arranged below auxiliary contact, main shaft is arranged below support, rotary cantilever is arranged on main shaft, the lower end of this cantilever and the middle part of main contact are hinged, it is characterized in that: utilize the hinged rotating lever of axle on support, the upper end of this rotating lever contacts the last end in contact of lower end and cantilever with push rod in the auxiliary contact; When main contact closure or disconnection, drive cantilever and rotate, drive rotating lever by cantilever and move, by rotating lever main contact closure and the state interlocking that disconnects are fed back on the auxiliary contact then.
Rotating lever, support, auxiliary contact, main shaft and main contact are installed on respectively on the pedestal, form the self-push self-pull type structure unit.On the push rod in auxiliary contact spring is arranged, resetting of rotating lever promoted by spring force.
Normally open contact and normally closed interlock are arranged in auxiliary contact; When the main contact of circuit breaker is closed, driving cantilever on the main shaft clockwise rotates and promotes rotating lever and be rotated counterclockwise around axle, upwards promote push rod in the auxiliary contact by the upper end of rotating lever, make normally open contact in the auxiliary contact become closure, normally closed interlock becomes disconnection; When the main contact of circuit breaker disconnected, the cantilever on the main shaft rotated counterclockwise and breaks away from rotating lever, and the counter-force effect of the spring on the rotating lever drawn stem transfers to reset voluntarily around the axle dextrorotation.
The utility model has the advantages that: when main contact is in the close position, directly utilize the change in location of main shaft, promote a rotating lever voluntarily, rotation by rotating lever, its other end directly promotes the push rod in the auxiliary contact, position mode in the auxiliary contact is changed, and promptly normally opened contact is converted to normally-closed contact, normally-closed contact is converted to normally opened contact.When contact disconnected, main shaft changed to the another location, and rotating lever is subjected to the effect of the spring force in the auxiliary contact and from horizontal reset, does not need to install additional back-moving spring and reach the purpose that resets.The simple, practical and reliable property of said structure is good.
