Abstract
The utility model provides a circuit breaker operating mechanism with a controllable opening distance function. The circuit breaker operating mechanism comprises a link mechanism, a crank arm changeover mechanism, a switch-on-off power system and a moving contact component, wherein the switch-on-off power system, the crank arm changeover mechanism and the moving contact component are connected sequentially; the link mechanism comprises a rod body, a big connection head and a small connection head; the big connection head is connected with the switch-on-off power system, the small connection head is connected with the crank arm changeover mechanism, and the two ends of the rod body are respectively connected with the big connection head and the small connection head in an adjustable manner. According to the circuit breaker operating mechanism with the controllable opening distance function, the connection structure is improved to a separated type structure, the big connection head and the small connection head can be adjusted on the rod body to change the distance between the big connection head and the small connection head, so as to realize the purpose of opening distance controlling, and to guarantee the service life and the high reliability of the circuit breaker.
Description
Technical field
The utility model relates to breaker technical field, relates in particular to a kind of circuit breaker operation mechanism having out apart from controllable function.
Background technology
For the operating mechanism of circuit breaker, generally include linkage, connecting lever changeover mechanism, divide-shut brake dynamical system and moving contact component, bar linkage structure is to be connected between connecting lever changeover mechanism and divide-shut brake dynamical system, because existing bar linkage structure is one, pitch-row is fixed, cannot regulate, under the accumulated error of other parts, cause out apart from bigger than normal or less than normal, can affect like this circuit breaker performance and life-span.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the opening apart from nonadjustable problem of circuit breaker operation mechanism in prior art, the utility model provide a kind of have out apart from the circuit breaker operation mechanism of controllable function solve the problems referred to above by large connector and little connector with adjustable connection of shaft.
The utility model solves the technical scheme that its technical problem adopts: a kind of circuit breaker operation mechanism having out apart from controllable function, comprise linkage, connecting lever changeover mechanism, divide-shut brake dynamical system and moving contact component, described divide-shut brake dynamical system, linkage, connecting lever changeover mechanism is connected successively with moving contact component, described linkage comprises shaft, large connector and little connector, described large connector is connected with described divide-shut brake dynamical system, described little connector is connected with described connecting lever exchanging structure, described shaft two ends are respectively with large connector with little connector is adjustable is connected.
Concrete, two of described shaft is provided with screw thread, and a nut is respectively installed, for the position of described large connector and little connector after secured adjusted.
Concrete, described connecting lever changeover mechanism comprises connecting lever and connecting plate, and described little connector is installed and is connected with one end of described connecting lever, and other one end of described connecting lever is connected with described moving contact component
The beneficial effects of the utility model are, this have out apart from the circuit breaker operation mechanism of controllable function Innovation of Connection is become to Split type structure, large connector and little connector can regulate on shaft, change the distance between large connector and little connector, thereby reach out apart from controlled object, may ensure like this life and reliability of circuit breaker.
