Embodiment
In conjunction with specific embodiments the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of control system of electric operating mechanism of circuit-breaker, comprises epipleural 9, lower side panel 10, gear 5, ratchet 7, limit shaft 8, output shaft 3, sensitive switch 1, output sleeve 4 and controls cam 2.
Output shaft 3 rotates and is arranged between epipleural 9 and lower side panel 10, output sleeve 4 and control cam 2 are fixedly installed on output shaft 3 respectively, control cam 2 offers the first bayonet socket 21, output sleeve 4 offers the second bayonet socket 41, first bayonet socket 21 with the second bayonet socket 41 towards identical.
Control cam 2 to be positioned at below output sleeve 4 and to be positioned on lower side panel 10, sensitive switch 1 is arranged on the lower side panel 10 of control cam 2 side, the toggle 11 of sensitive switch 1 coordinates with the first bayonet socket 21, when the first bayonet socket 21 that output shaft 3 rotates drive control cam 2 coordinates with toggle 11, the toggle 11 of sensitive switch 1 ejects.
Gear 5 is socketed on output sleeve 4, formed between gear 5 and output sleeve 4 and be rotatably assorted, gear 5 and external motor form transmission and coordinate, ratchet 7 is arranged on gear 5, in the middle part of ratchet 7 with form elastic rotation formula between gear 5 and coordinate, concrete, elastic rotation structure in the middle part of ratchet 7 and between gear 5 is: formed through bearing pin and gear 5 in the middle part of ratchet 7 and be rotationally connected, reduction torsion spring 6 is socketed on bearing pin, reduction torsion spring 6 connects ratchet 7 and gear 5, time static, reduction torsion spring 6 drives laminating output sleeve 4 outer face, ratchet 7 the inner.The inner of ratchet 7 coordinates with the second bayonet socket 41 on output sleeve 4, for improving the stability that ratchet 7 the inner coordinates with output sleeve 4, the inner of ratchet 7 forms the 3rd bayonet socket 71 being used for coordinating with the second bayonet socket 41, and the outer end of ratchet 7 forms the slip curved surface being used for coordinating with limit shaft 8.When gear 5 rotates, the 3rd bayonet socket 71 of ratchet 7 the inner coordinates with the second bayonet socket 41, promotes output sleeve 4 and output shaft 3 rotates through the second bayonet socket 41.
Limit shaft 8 is fixedly installed on lower side panel 10, and limit shaft 8 coordinates with the outer end of ratchet 7, and when ratchet 7 rotates with gear 5, ratchet 7 outer end is stirred through limit shaft 8 and driven ratchet 7 the inner to depart from the second bayonet socket 41.
There is in first bayonet socket 21 cushion space for dodging toggle 11.As shown in Figure 4, after motor-operating mechanism energy storage terminates, the output shaft 3 of circuit breaker operation mechanism rotates voluntarily, stops after driving output sleeve 4 and controlling the certain angle of cam 2 synchronous rotary.Owing to there is above-mentioned cushion space, the toggle 11 of sensitive switch 1 still ejects in the first bayonet socket 21 controlling cam 2, and external impetus motor power keeps off-state, plays the protective effect with toggle 11.
The putting position of setting electric operating mechanism of circuit-breaker, lower side panel 10 is in below, epipleural 9 is positioned at top, output shaft 3 is vertically arranged between both sides, as shown in Figure 1, the toggle 11 of sensitive switch 1 is pressed into by the outer rim controlling cam 2, as shown in Figure 2, thus external motor is in work, suppose that now gear 5 rotates clockwise, ratchet 7 is under the effect of reduction torsion spring 6, the inner of ratchet 7 is close on the outer face of output sleeve 4, outer face is provided with the second bayonet socket 41, second bayonet socket 41 do counterclockwise direction towards output sleeve 4, therefore, along with the rotation of ratchet 7, 3rd bayonet socket 71 of ratchet 7 the inner coordinates with the second bayonet socket 41 on output sleeve 4, and drive output sleeve 4 to rotate clockwise together, the rotation of output sleeve 4 drives output shaft 3, control cam 2 to rotate, output shaft 3 is connected with outside stored energy mechanism, therefore energy storage is realized.
As shown in Figure 3, at the end of energy storage, the toggle 11 of sensitive switch 1 is in the first bayonet socket 21 of control cam 2, toggle 11 ejects, sensitive switch 1 controls external motor and quits work, now, if motor driven gear 5 under the effect of inertia is rotated further, when the 3rd bayonet socket 71 of ratchet 7 the inner is close to the second bayonet socket 41, ratchet 7 outer end is through the stop of limit shaft 8, drive the inner outwards motion of ratchet 7, thus avoid ratchet 7 and drive output sleeve 4 to rotate, thus avoid the impact of motor inertia to output shaft 3.
Outside stored energy mechanism connects output shaft 3; after energy storage is complete; stored energy mechanism can drive output shaft 3 to do a percussion action rotated voluntarily; output shaft 3 and output sleeve 4 can be driven to turn over certain angle; due to the first bayonet socket 21 having cushion space; the toggle 11 of sensitive switch 1 still ejects in the first bayonet socket 21 controlling cam 2, and external impetus motor power keeps off-state, plays the protective effect with toggle 11.
As shown in Figure 4, releasing when circuit breaker can, the main shaft of circuit breaker operation mechanism drives output shaft 3 to rotate and rotates clockwise certain angle, now the toggle 11 of sensitive switch 1 is pressed into by the outer rim controlling cam 2, thus controls external motor work, and external motor driven gear 5 rotates clockwise, gear 5 drives ratchet 7 to move, 3rd bayonet socket 71 of ratchet 7 the inner is joined Merging zone method output sleeve 4 with the second bayonet socket 41 of output sleeve 4 and is rotated, and output sleeve 4 drives output shaft 3 to rotate, and realizes energy storage.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
