Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of circuit breakers, in particular to a reclosing circuit breaker with controller protection. Background Art
[0002] The existing reclosing products have built-in electric mechanisms and are fastened and sealed by a face cover and screws around them. As customers have increasingly higher requirements for the breaking capacity of products, under conditions of larger breaking capacity, the gas energy generated when the contacts are broken will spray out from the gap in the middle cover handle and the wiring slots in the middle cover to impact the face cover. The face cover often cannot withstand the energy impact, resulting in the face cover bursting and damage. At the same time, the ejected airflow rushes into the control panel where the face cover is installed. The control panel cannot withstand the large airflow impact and is blown away by the airflow, leading to failure. Utility Model Content
[0003] In view of this, an object of the present invention is to provide a reclosing circuit breaker with controller protection which has high safety and long service life.
[0004] In order to achieve the above purpose, the utility model adopts a reclosing circuit breaker with controller protection, including a base, a middle cover arranged on the base, and a surface cover arranged on the middle cover. A controller is arranged on the inner wall of the surface cover, a viewing window is opened on the outer wall of the surface cover corresponding to the controller, and protective ribs are arranged on the inner wall of the surface cover in three directions corresponding to the controller.
[0005] The beneficial effects of the above structure are: a controller is provided on the inner wall of the cover, and the protective ribs are used to strengthen and fix the controller in three directions, which can effectively protect the airflow from directly impacting the control panel, thereby improving the safety and service life of the controller; a viewing window is provided on the outer wall of the cover corresponding to the controller, so that the user or operator can easily observe the status and working condition of the controller, which is convenient for monitoring and maintenance and improves the convenience of use.
[0006] The utility model is further configured that the controller includes a control panel, and a pressure plate is further provided on the inner wall of the cover, and the pressure plate is closely attached to the upper surface of the control panel. By the pressure plate being closely attached to the upper surface of the control panel, the control panel can be effectively fixed to prevent the controller screen from being opened by the impact of airflow.
[0007] The utility model is further configured to include a handle mechanism on the base, the handle mechanism includes a handle, a handle hole is opened on the middle cover, the upper end of the handle extends into the middle cover through the handle hole opened in the middle cover, fastening columns are respectively provided on both sides of the middle cover corresponding to the handle, nuts are embedded in the fastening columns, screw holes are provided on the inner wall of the face cover corresponding to the fastening columns, and the screws are connected with the nuts. By adding the fastening columns and the screw locking design, the anti-impact ability of the face cover is increased, and the face cover is protected from being cracked or damaged by the impact of gas energy.
