Description
Technical field
The utility model belongs to breaker technical field, is specifically related to a kind of switching adjustment type circuit breaker.
Background technology
Generally all be provided with circuit breaker in a power distribution system; it generally can meet power-off protection function; but when it uses at part Code in Hazardous Special Locations; do not disconnect under requiring to run into the situations such as overload, short circuit, decompression at circuit breaker; still holding circuit is powered continuously; trip action cannot be ensured by link gearing and not open circuit in the circuit breaker of prior art; affect its stability in use and safety in utilization to a certain extent; be difficult to the use meeting special circumstances, applicability is restricted to a certain extent.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, and stability in use is good and the switching adjustment type circuit breaker that applicability is wide.
The technical scheme realizing the utility model object is a kind of switching adjustment type circuit breaker, comprise housing, be arranged on the moving contact in described housing, fixed contact and shell fragment, described moving contact be arranged on described shell fragment with and coordinate with the activity of described fixed contact, dropout cut-off structure is provided with and not cut-off structure of threading off in described housing, described dropout cut-off structure and described dropout not cut-off structure are in parallel and arrange, selection control lever is not provided with between cut-off structure at described dropout cut-off structure and described dropout, described dropout cut-off structure and described dropout not cut-off structure are all connected with described movable contact spring.
In described housing, be provided with processor, the selection input key be connected with described processor, described processor is connected with described selection control lever by control lever driver.
In described housing, be also provided with the dropout be connected with described processor select display and communication interface circuit.
The warning indicator be connected with described processor is also provided with in described housing.
The utility model has positive effect: structure of the present utility model is simple, convenient to use, it is provided with thread off not cut-off structure and dropout cut-off structure, in use can to select as required to thread off not cut-off structure or dropout cut-off structure, be applicable to more special situation, improve the scope of application of circuit breaker, and stability in use is strong, practicality is better; And in housing, be also provided with processor, select input key, can by selecting the selection of input key realization to releasing structure, convenient to use, but also be provided with selection display of threading off, effectively can show the using state of releasing structure, intuitive is stronger, convenient better selection, usability is good.
Accompanying drawing explanation
In order to make content of the present utility model be more likely to be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein:
