Description
Technical field
The present invention relates to a kind of operating mechanism of low-voltage circuit breaker, 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 cannot electric switch-on, has limited the application of circuit breaker aspect the distribution motorized.In order to solve the electronic closing function of circuit breaker, producer has proposed many technical schemes as " electric switch-on device of breaker 00208566.6 ", " Leakage Circuit Breaker Dual-Use Switch Rack Device 2284818.5 " etc., though these technical schemes have tentatively solved the electric switch-on problem, but still there is very big deficiency.Adopt by motor+screw mandrel scheme as " electric switch-on device of breaker 00208566.6 " patent: the mechanism in the production practices, but exist screw mandrel easily stuck, combined floodgate common fault such as be difficult for putting in place, and can not realize closing by hand, screw mandrel requirement on machining accuracy height, production cost and production technology all have problems." Leakage Circuit Breaker Dual-Use Switch Rack Device 2284818.5 " adopts the tooth bar meshing schemes, solved electronic and problem closing by hand, but electronic and closing by hand must be changed by turning knob, very inconvenient in actual use, and forget under the rotation conversion knob situation the user, the manual operation circuit breaker, circuit breaker handle ruptures easily.Because the limitation of tooth bar engagement, when the user rotated the conversion knob from manual switch to electric operating, tooth bar did not mesh stuck easily, caused breaker electric operation to lose efficacy.
Summary of the invention
The object of the invention be to design a kind of simple in structure, easy to operate, the life-span is long, cost is low, volume is less, electric operating mechanism of circuit-breaker, can realize manually and the electric operating circuit breaker, and the manual/electric operation need not to change.
Its technical scheme: device is made of pivot pin (1), swing transverse arm (2), motor (3), bearing (4), unidirectional cantilever (5), circuit breaker handle (6).Motor (3) and pivot pin (1) are installed on the circuit breaker;
Swing transverse arm (2) one ends have deep-slotted chip breaker, and swing transverse arm (2) is enclosed within on the pivot pin (1) by deep-slotted chip breaker, and swing transverse arm (2) other end has hole slot, clamps circuit breaker handle (6) by hole slot;
Unidirectional cantilever (5) is installed on the output shaft of motor (3), is with spring (51) on the output shaft (31) of motor (3), an end of spring (51) is fixed on the unidirectional cantilever (5);
Bearing (4) is installed on the unidirectional cantilever (5), and bearing (4) is placed in the microscler chute of swing transverse arm (2).
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, can realize that manual and electric operation and volume are less.
Description of drawings
Fig. 1 is a mechanical schematic diagram of the present invention
Fig. 2 is a unidirectional cantilever scheme of installation of the present invention.
Specific embodiments
Be described in detail specific embodiments below in conjunction with accompanying drawing.
With reference to figure 1
The present invention is made of pivot pin (1), swing transverse arm (2), motor (3), bearing (4), unidirectional cantilever (5), circuit breaker handle (6).Motor (3) is installed on the circuit breaker, and pivot pin (1) is installed on the circuit breaker by support (11).Swing transverse arm (2) one ends have deep-slotted chip breaker, and swing transverse arm (2) is connected with pivot pin (1) by deep-slotted chip breaker, and swing transverse arm (2) other end has hole slot, clamps circuit breaker handle (6) by hole slot.Unidirectional cantilever (5) is installed on the output shaft of motor (3), bearing (4) is installed on the unidirectional cantilever (5).Bearing (4) is placed in the middle microscler chute of swing transverse arm (2).
After motor (3) started for electricity, motor shaft drove unidirectional cantilever (5) and moves in a circle (establish and turn clockwise), and because of unidirectional cantilever (5) other end is with bearing (4), bearing (4) is placed in the microscler chute of swing transverse arm (2).When unidirectional cantilever (5) rotated, bearing (4) slided to the right in the microscler chute of swing transverse arm (2), and an end of compressing chute drive swing transverse arm (2) drives circuit breaker handle (6) and moves downward, and the other end of swinging transverse arm (2) simultaneously moves upward.Because of an end of swinging transverse arm (2) is enclosed within on the pivot pin (1), when driving handle (6) near the bottom, the deep-slotted chip breaker top in swing transverse arm (2) left side contacts with pivot pin (1).Pivot pin this moment (1) is as the fulcrum of swing transverse arm (2) drive circuit breaker handle (6) motion.After this swing transverse arm (2) and move downward moment and progressively strengthen, the thrust of generation enough makes handle (6) be fastened as merit again.After motor turned over 180 degree, circuit breaker handle (6) also arrived the bottom, has finished separating brake or has pulled work again.
This moment, unidirectional cantilever (5) continued rotation if motor does not cut off the power supply, and bearing this moment (4) to motion in the other direction, drives swing transverse arm (2) and moves upward with handle (6) in the microscler chute of swing transverse arm (2).Because of an end of swinging transverse arm (2) is enclosed within on the pivot pin (1), when driving handle (6) near the top, the deep-slotted chip breaker bottom in swing transverse arm (2) left side contacts with pivot pin (1).Pivot pin this moment (1) is as the fulcrum of swing transverse arm (2) drive circuit breaker handle (6) motion.After this swing transverse arm (2) moment that moves upward and progressively strengthen, the thrust of generation enough makes handle (6) close a floodgate successfully.
Referring to Fig. 2.
Be with spring (51) on the output shaft (31) of motor (3), spring (51) colludes on unidirectional cantilever (5).Unidirectional cantilever (5) is connected with bearing (4) by bolt (52).When motor (3) rotates, because of tightly tightening up, torsion cause spring (51) embraces output shaft (31), finish the electric switch-on process thereby drive unidirectional cantilever (5) rotation, the combined floodgate principle is seen the description of Fig. 1.When the needs closing by hand, motor does not change, and pulls unidirectional cantilever (5) with hand or instrument and goes up bolt (52), and it is opposite with direction of motor rotation to pull direction.Spring this moment (51) is subjected to opposite torsion, and spring (51) is relaxed no longer to be contacted with motor shaft.Thereby unidirectional cantilever can not be subjected to the resistance of motor shaft and rotate the closing by hand process of finishing this moment, and the combined floodgate principle is seen the description of Fig. 1.
