Abstract
The utility model discloses a manual tripping device for a circuit breaker. A fixed plate (4) of the manual tripping device is arranged on a circuit-breaker handcart, a microswitch bracket (3) is connected with the fixed plate (4), and a microswitch (2) is arranged on the microswitch bracket (3) and connected with an operating rod (1); the rear part of the operating rod (1) is connected with a connecting rod (5), and a spring ring washer (6) and a spring (7) of the spring ring washer (6) are clamped and sleeved on the connecting rod (5); the connecting rod (5) is contacted with another rear connecting rod (9) in a fixed-frame hole (8) after penetrating through the fixed plate (4); and the other end of the rear connecting rod (9) is connected with a driving piece (10), the driving piece (10) is connected with a driving shaft (11), and the driving shaft (11) is connected with a movable contact inside the circuit breaker. The manual tripping device has a simple structure and is convenient to operate, and the trapping of the movable contact inside a direct-current fast circuit breaker can be realized by only operating a tripping operating rod outside the circuit-breaker handcart so as to achieve the purpose of rapid, convenient and safe operation.
Description
Technical field
The utility model relates to direct current supply complete set of equipments field, the manual tripping device on particularly a kind of direct current quick breaker.
Background technology
At present, direct current quick breaker is generally realized threading off in the electromagnetic trip mode or in sheet metal dropout mode.Its shortcoming is when work, be subject to big electric current, electrical network, circuit or other electronic jamming, cause the dropout misoperation or do not thread off for a certain reason, can't allow administrative staff correctly judge, can cause service life of equipment to shorten, even damage, thereby make troubles and may injure personal safety to production.
The utility model content
The purpose of this utility model provides a kind of simple in structure, easy to operate manual tripping device, makes it after installing on the direct current quick breaker, and operation can realize manually tripping function fast and safely on circuit breaker panel.
The purpose of this utility model is realized by following technical scheme: (reading comprehension for convenience in the narration has been placed on the label in the accompanying drawing back of part name, but can not have understood the scope of the little technical scheme of Hui Shrink thus)
Fixed head 4 in the utility model is arranged on the circuit breaker cart, has a sensitive switch support 3 to join with fixed head 4, and sensitive switch 2 is located on the support 3 and with action bars 1 and links to each other; Action bars 1 rear portion connects a connecting rod 5, is covered with a spring flange 6 and spring 7 thereof on this connecting rod 5; This connecting rod 5 passes fixed head 4 and contacts with another back link 9 in fixed mount hole 8; The other end of back link 9 connects driver blade 10, and driver blade 10 connects power transmission shaft 11, and power transmission shaft 11 links to each other with the moving contact of circuit breaker inside.
Described two connecting rods 5,9 are made by insulating material.
The beneficial effects of the utility model:
The utility model is simple in structure, and is easy to operate, only by operating in the dropout action bars of handcart outside, just can realize that the moving contact of direct current quick breaker inside is threaded off, thereby reaches purpose quick, convenient, safety operation.
Description of drawings
Accompanying drawing is a perspective view of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described, but embodiment should not be construed as restriction of the present utility model.
The disclosed structure of accompanying drawing is exactly the structure of an embodiment of the utility model.
Among the figure, the corresponding relation of each label and parts is: the 1-action bars; The 2-sensitive switch; 3-sensitive switch support; The 4-fixed head; The 5-connecting rod; The 6-spring flange; The 7-spring; 8-fixed mount hole; The 9-back link; The 10-driver blade; The 11-power transmission shaft.
Consult accompanying drawing, fixed head 4 is installed on the handcart, by operation dropout action bars 1, touches the sensitive switch 2 that is installed on the sensitive switch support 3 simultaneously and provides control signal.Strength during operation dropout action bars 1 is by connecting rod 5 extrusion spring ring washers 6 and spring 7.Back link 9 can freely be active in the fixed mount hole 8 front and back, and back link 9 promotes driver blade 10 linkage power transmission shafts 11 after obtaining power, and power transmission shaft 11 links with the moving contact of direct current quick breaker, thereby has realized the manual purpose of dropout fast and safely.
Described connecting rod 5 and back link 9 are made by insulating material.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.If of the present utility model these are revised and modification belongs within the scope of basic design of the present utility model or equivalent technologies, then the utility model also should comprise these changes and modification interior.
If the content that is not described in detail is arranged, then belong to this area professional and technical personnel's technique known in this specification, repeat no more herein.
Claims (2)
