Abstract
The utility model discloses a transmission device in an electric driven structure of a circuit breaker. The transmission device adopts an electromotor as the power, and gears as the sub-transmission to drive a guide board mechanism of a connection rod and finally change the circle movement of the electromotor into a straight-line reciprocating movement, resulting in accurate completion of switching on, disconnection and free tripping.
Description
One, technical field
The utility model relates to a kind of transmission device that is used for moulding shell class circuit breaker electric driving mechanism, belongs to low-voltage electrical apparatus switching technique field.
Two, background technology
The existing transmission device of moulding in the shell class circuit breaker electric driving mechanism, its structure is that two solenoids are arranged, and is interior cored, and the exposed junction of two iron cores is with the two ends of a connecting rod respectively and is articulated and connected, connecting rod is enclosed within on the power transmission shaft by the middle part square hole, and shifting fork mechanism is established in the power transmission shaft lower end.This mechanism is a power with the electromagnetic attraction, during driving circuit breaker is had tangible impact, and the operating characteristics of circuit breaker is had certain influence.In addition, this class mechanism also owes complete to " combined floodgate, disconnection, trip free " three kinds of operating states demonstrations of circuit breaker.
Three, summary of the invention
Problem in view of above-mentioned existence, the purpose of this utility model provides a kind of compact conformation, stable drive, precision height, both can be electronic, also can be manual, but also can demonstrate transmission device in the circuit breaker electric driving mechanism of operating states such as " combined floodgate, disconnection, trip frees " of circuit breaker significantly.
Summary of the invention of the present utility model is: be power with the motor, adopt the gear pair transmission, the drivening rod guide agency, the circular motion of motor changes straight reciprocating motion into the most at last, thereby finishes operating states such as combined floodgate to circuit breaker, disconnection, trip free exactly.
Through the utility model after the above-mentioned design compared with prior art, have the following advantages:
1, scientific structure, reasonable, owing to adopted motor driven, the gear pair transmission, the connecting rod guide plate structure is steadily, reliably.
2, in electrically driven (operated) whole system, there is not relative slip link, therefore, combined floodgate, separating brake, to detain the time more more accurate.
3, transmission adopted rolling friction, the transmission resistance is less.
4, whole driving mechanism both can be electronic, also can be manual, but also can demonstrate the operating states such as " combined floodgate, disconnection, trip frees " of circuit breaker significantly.

Five, specific embodiments
Transmission device in the circuit breaker electric driving mechanism includes a housing 1, is provided with power transmission shaft 3, cam 2, connecting rod 5, guide plate 7 in housing 1, and power transmission shaft 3 is provided with clutch.This clutch is made up of ratchet 11, ratchet 15, support plate 16, spring 14 and pivot pin 4, and support plate 16 is connected with gear 17, and ratchet 11 is connected with power transmission shaft 3 by pivot pin 4.The upper end of power transmission shaft 3 connects cam 2, and cam 2 is provided with the groove that can insert manual handle 13, and the lower end of power transmission shaft 3 connects connecting rod 5, and connecting rod 5 is combined closely by bearing on it 6 and guide plate 7.In support plate 16, spring 14 is installed in the back of ratchet 15, and ratchet 11 constitutes self-locking with ratchet 15.In addition, with cam 2 that power transmission shaft 3 upper ends are connected on, be provided with the indication piece 20 that is used to show working state of circuit breaker, be divided into red, white, green three kinds of colors on the indication piece, be respectively applied for demonstration circuit breaker three kinds of operating states such as " combined floodgate, disconnection, trip frees ".
Working method of the present utility model is achieved like this:
After motor is received actuating signal, drive support plate 16 through gear reduction and clockwise rotate.At this moment, under spring 14 effects, ratchet 11, ratchet 15 engagements, power is passed to ratchet 11 through ratchet 15, passes to power transmission shaft 3 through pivot pin 4 again, and drivening rod 5 rotates together, and the bearing 6 corresponding circular motion of doing carry out electronic thereby drive 7 pairs of circuit breakers of guide plate.Both cooperate electronic dependence cam 2 and sensitive switch 19 and control.When 3 times end links 5 of power transmission shaft turn over 180 when spending clockwise, circuit breaker is finished once " combined floodgate " or " separating brake/button " again action.At this moment, the cam 2 of power transmission shaft 3 upper ends also just turns over 180 degree clockwise, under the effect of cam 2, cuts off the electricity supply by sensitive switch 19, and motor is stopped.
During hand drive, manually handle 13 inserts in power transmission shaft 3 upper end slot and turns clockwise, and drives bearing 6 and does the circumference rotation, and guide plate 7 is moved up and down, and circuit breaker is carried out manually.In the time of manually, ratchet 11 is driving link and clockwise rotates that ratchet 11 can not mesh with ratchet 15, and clutch is inoperative, and manual route and electronic route are broken away from, and like this, manually just compares safety, and resistance is also smaller.
Clutch not only makes safety when manual, easily, and also making circuit breaker 8 thread off to show becomes possibility.When circuit breaker 8 was threaded off from "on" position, circuit breaker handle forced trolley type guide plate 7 to move down, and guide plate 7 makes bearing 6 rotate around power transmission shaft 3 clockwise directions, drove ratchet 11 and clockwise rotated.At this moment, ratchet 11 does not mesh with ratchet 15, and clutch is inoperative, has cut off the resistance of gear pair.Therefore, when circuit breaker tripping, can make cam 2 turn over an angle clockwise very like a cork, promptly transfer " trip free " position to by " combined floodgate " position.Because cam 2 is provided with indication piece 20, like this, can observe circuit breaker 8 residing states such as " combined floodgate, disconnection, trip frees " very easily by the viewport on the housing 1.
