Description

Electric switch-on device of breaker
Technical field
The present invention relates to a kind of motor-operating mechanism of low-voltage circuit breaker automatic closing, belong to electromechanical integration technology area.
Background technology
Have in the low-voltage distribution system and used low-voltage circuit breaker widely, protections such as short circuit, overload, electric leakage are provided for system.But common circuit breaker can not automatic closing, has limited the application of circuit breaker aspect power distribution automation.In order to solve the circuit breaker automatic switching-in function, producer has proposed many technical schemes as " electric switch-on device of breaker 00208566.6 ", " Intelligence Electric Circuit Breaker Operative Mechanism 03131888.6 " etc.All there are defectives such as cost height, the life-span is short, volume is bigger in these technical schemes.Adopt by motor+screw mandrel scheme as " electric switch-on device of breaker 00208566.6 " patent: " motor connects screw mandrel; be with the slide block that screw thread is worked in coordination on the screw mandrel; slide block links to each other with male contact handle; motor and screw mandrel are fixed on the support, the bound bit switch is fixed on touching place of slide block or plug-in strip stroke two ends terminal point." but in production practices such mechanism, but exist screw mandrel easily stuck, closing a floodgate common fault such as is difficult for putting in place, and screw mandrel requirement on machining accuracy height, production cost and production technology all have problems." Intelligence Electric Circuit Breaker Operative Mechanism " adopts the mechanism of series-wound motor and planetary gear speed reducing mechanism and boss and control lever composition, also has problems such as many costs of part height.Also there is a shortcoming in these schemes, and motor-operating mechanism has almost occupied most of area on circuit breaker surface and highly higher, will cause the circuit breaker volume of charged pneumatic operating mechanism to increase considerably.
Summary of the invention
The object of the invention is to design a kind of simple in structure, the life-span is long, cost is low, volume is less electric switch-on device of breaker.
Its technical scheme: install by motor (1), connecting lever (2), circuit breaker handle (4) activity swing arm (5), guide rail (6), spring formations such as (8).Motor (1) and guide rail (6) are installed on the circuit breaker, are with spring (8) on the guide rail (6).Activity swing arm (5) one ends are enclosed within on the guide rail (6), and an end is connected with short-circuiting device handle (4).Have chute (7) in the middle of the activity swing arm (5).Be connected with connecting lever (2) on the output shaft of motor (1), connecting lever (2) one ends connect motor (1), and the other end is with bearing (3), and bearing (3) is placed in the chute (7) of activity swing arm (5).
The invention has the advantages that part is few, simple in structure, thus convenient the installation, the life-span is also long, cost is lower, and volume is less.
Description of drawings
Fig. 1 is a mechanical schematic diagram of the present invention
Fig. 2 is a structure top view of the present invention
With reference to figure 1, Fig. 2 the present invention by motor (1), connecting lever (2), circuit breaker handle (4), activity swing arm (5), guide rail (6), spring formations such as (8).Motor (1) and guide rail (6) are installed on the circuit breaker, are with spring (8) on the guide rail (6).Activity swing arm (5) one ends are enclosed within on the guide rail (6), and an end is connected with short-circuiting device handle (4).Have chute (7) in the middle of the activity swing arm (5).Be connected with connecting lever (2) on the output shaft of motor (1), connecting lever (2) one ends connect motor (1), and the other end is with bearing (3), and bearing (3) is placed in the chute (7) of activity swing arm (5).
After motor (1) started for electricity, motor shaft drove connecting lever (2) and moves in a circle (establish and turn clockwise), and because of connecting lever (2) other end is with bearing (3), bearing (3) is placed in the chute (7) of activity swing arm (5).When connecting lever (2) was movable, bearing (3) slided to the right in chute (7), and an end of compressing chute (7) drive activity swing arm (5) drives circuit breaker handle (4) and moves downward, and the other end of activity swing arm simultaneously (5) also moves downward.Because of an end of activity swing arm (5) is enclosed within on the guide rail (6), have spring (8) on the guide rail (6) simultaneously.When activity swing arm (5) drove handle (4) near the bottom, spring (8) will be by activity swing arm (5) compression, and spring (8) is as the fulcrum of activity swing arm (5) drive circuit breaker handle (4) motion.
After motor turned over 180 degree, circuit breaker handle (4) also arrived the bottom, has finished separating brake or has pulled work again.
This moment is not if motor cuts off the power supply, connecting lever (2) continues rotation, bearing this moment (3) moves to opposite direction in chute (7), drive activity swing arm (5) moves upward, the end that activity swing arm (5) is enclosed within on the guide rail (6) moves upward, when near the top, activity swing arm compression spring (8) is as fulcrum.Behind motor Rotate 180 degree, activity swing arm (5) drives circuit breaker handle (4) and arrives peak, finishes feed motion.
Specific embodiments
Be described in detail specific embodiments the present invention by motor (1), connecting lever (2), circuit breaker handle (4) below in conjunction with Fig. 1, Fig. 2, activity swing arm (5), guide rail (6), spring formations such as (8).Motor (1) and guide rail (6) are installed on the circuit breaker, are with spring (8) on the guide rail (6).Activity swing arm (5) one ends are enclosed within on the guide rail (6), and an end is connected with short-circuiting device handle (4).Have chute (7) in the middle of the activity swing arm (5).Be connected with connecting lever (2) on the output shaft of motor (1), connecting lever (2) one ends connect motor (1), and the other end is with bearing (3), and bearing (3) is placed in the chute (7) of activity swing arm (5).
After motor (1) started for electricity, motor shaft drove connecting lever (2) and moves in a circle (establish and turn clockwise), and because of connecting lever (2) other end is with bearing (3), bearing (3) is placed in the chute (7) of activity swing arm (5).When connecting lever (2) was movable, bearing (3) slided to the right in chute (7), and an end of compressing chute (7) drive activity swing arm (5) drives circuit breaker handle (4) and moves downward, and the other end of activity swing arm simultaneously (5) also moves downward.Because of an end of activity swing arm (5) is enclosed within on the guide rail (6), have spring (8) on the guide rail (6) simultaneously.When activity swing arm (5) drove handle (4) near the bottom, spring (8) will be by activity swing arm (5) compression, and spring (8) is as the fulcrum of activity swing arm (5) drive circuit breaker handle (4) motion.
After motor turned over 180 degree, circuit breaker handle (4) also arrived the bottom, has finished separating brake or has pulled work again.
This moment is not if motor cuts off the power supply, connecting lever (2) continues rotation, bearing this moment (3) moves to opposite direction in chute (7), drive activity swing arm (5) moves upward, the end that activity swing arm (5) is enclosed within on the guide rail (6) moves upward, when near the top, activity swing arm compression spring (8) is as fulcrum.Behind motor Rotate 180 degree, activity swing arm (5) drives circuit breaker handle (4) and arrives peak, finishes feed motion.
Used in the present embodiment bearing (7) adopts common Miniature ball bearing, and motor adopts the synchronous reversible alternating current machine of magneto.Because the present embodiment part is few, thereby with low cost, volume is very little, and the life-span is long not fragile, has bigger market potential.
