Abstract
A drive unit for the electric operation mechanism of breaker is composed of drive axle, cam, slide block and cluth unit consisting of two clutches, axle pin and restoring spring. The axle pin is in touch with gear. Said drive axle with said clutch unit on it has recess for handle at one end and is linked to cam at another end. The slide block is in close contact with cam. Its advantages include compact structure, reliable performance, convenient application, small size and smooth operation without obvious inpact and vibration.
Description
What the present invention relates to is a kind of transmission device that is used for electric operating mechanism of circuit-breaker, belongs to the voltage switch technical field.
Transmission device in the motor-operating mechanism of existing circuit breaker, its structure is that two power transmission shafts are arranged, wherein a power transmission shaft is to connect motor-operating mechanism, another root power transmission shaft is to connect the manual operation handle, structure also includes cam, slide block, when after the motor-operating mechanism conducting of circuit breaker, opening operation, the binding site between cam, the slide block is separated.Dispose the motor-operating mechanism of the circuit breaker of such transmission device, volume is big, and complex structure has tangible impact shock during electric operating, influence and being used of low-voltage release, and " close, separating brake, button again " three kinds of operating state reflections owe obvious.
The objective of the invention is to defective, propose a kind of band clutch and, be used in the motor-operating mechanism of circuit breaker and can dwindle space minimizing volume, and can effectively improve the reliability of service behaviour only with a transmission shaft drive at above-mentioned existence.
Technical solution of the present invention:
Include power transmission shaft 1, cam 2, slide block 3, on power transmission shaft 1, be provided with arrangement of clutch, this arrangement of clutch is made up of two clutches 4,5 and axle Xiao 6, back-moving spring 7, axle Xiao 6 wherein connects reducer gear 9, on an end of power transmission shaft 1, have the groove that can insert manual operation handle 10, the other end of power transmission shaft 1 connects cam 2, cam 2 keeps combining closely with slide block 3, and it is that tight contact the by the upper plate 18 on the ball bearing on the cam 2 17 and the slide block 3 realized that cam 2 and slide block 3 maintenances are combined closely.
Two sides of slide block 3 respectively have a boss, and a connecting rod 8 is arranged between them.
Advantage of the present invention:
The structural design compactness of this device is reasonable simply again, dependable performance, easy to use, the motor-operating mechanism that is used for circuit breaker can make manual operation and electric operating adopt the rotation of same power transmission shaft to realize hand, electric operating, the volume of mechanism has been reduced in the space that has dwindled the motor-operating mechanism of circuit breaker, make the also compact advantages of simple of structure of the motor-operating mechanism of circuit breaker, smooth operation does not have tangible impact shock in the time can effectively guaranteeing at electric operating on the service behaviour, help and being used of under-voltage release, can reflect circuit breaker " combined floodgate " significantly, " separating brake ", operating states such as " buttons again ".
Accompanying drawing 1 is a structural representation of the present invention
Accompanying drawing 2 is the A-A rotation cut-away views among Fig. 1.
Accompanying drawing 3 is that 11 among the slide block two side boss structural representation figure are colour code direction boards, the 12nd, shell, 13, the 14th, mounting bracket, the 15th, circuit breaker, the 16th, colour code watch window, the 17th, ball bearing, 18, the 19th, upper and lower top board, the 20th, guide rail, the 21st, sensitive switch, the 22nd, pedestal.
Contrast Fig. 1, motor is after receiving electromotive signal, drive clutch 4 in the arrangement of clutch be arranged on the power transmission shaft 1 through gear reduction, 5, drive drive bearing 1 by axle Xiao 6 in the arrangement of clutch again, because the other end of drive bearing 1 is to connect cam 2, cam 2 is to combine closely with slide block 3 again, so axle Xiao 6 drives power transmission shaft 1 and has also driven cam 2, slide block 3 carries out the electricity operation, this moment, arrangement of clutch closed automatically, simultaneously because the effect of arrangement of clutch, make the dropout demonstration of circuit breaker 15 become possibility, owing to have on the end of power transmission shaft 1 and can insert manual operation handle 10, when manual operation, can be automatically and electrically operated deceleration system renunciation, make manual operation free and relaxed, electronic, manually be to adopt same through-drive, reduced the space of occupying because of manual-operating mechanism and optional feature thereof, thereby make compact conformation, also brought operational convenience, settled colour code direction board 11 on the power transmission shaft 1, can be by the operating states such as " closing; separating brake; detain again " of the 16 Direct observation circuit breakers 15 of the observation window on the shell 12.
Contrast Fig. 2, cam 2 is made clockwise direction and is rotated 180 degree, promptly finish once " combined floodgate " or " separating brake/detain again " action, ball bearing 17 is directly to be contained on the cam 2, make circular motion with cam 2 rotations, the upper plate 18 drive slide blocks 3 that promote on the slide block 3 move upward, make circuit breaker 15 combined floodgates (shown in Figure 2), then under the effect of cam 2, by sensitive switch 21 to cut off the electricity supply, after braking, ball bearing 17 stops at position shown in Figure 2 and closely contacts with upper plate 18, when circuit breaker 15 is threaded off, handle 10 drives slide block 3 and moves downward, 18 pairs of ball bearings 17 of upper plate are exerted pressure downwards, forcing cam 2 to make clockwise direction rotates, clutch 5 on the power transmission shaft 1 is also made clockwise direction and is rotated, because two clutches 4,5 sawtooth direction relations will make clutch 5 upwards rise, last disconnecting clutch 4 (clutch separates automatically), clutch 4 is not in company with clutch 5 rotations, and will turn an angle with power transmission shaft 1 clockwise direction with the colour code direction board 11 of power transmission shaft 1 interlock, promptly finished " indication of threading off " action.When receiving " separating brake/detain again " signal, cam 2 remakes 180 degree clockwise directions rotations, and 17 pairs of lower roof plates 19 of ball bearing are exerted pressure, slide plate 3 is moved downward, finish " separating brake/detain again " action, cutting off the electricity supply, and is the work of getting ready of closing a floodgate once more by sensitive switch 21.
During manual operation, the manual operation handle 10 that inserts in the groove is done the clockwise direction rotation, drive ball bearing 17 rotations, driving slide block 3 again moves up and down, circuit breaker 15 is carried out " closing; separating brake; detain again " operation, moving about 180 degree of handle 10 revolutions, promptly finish once " combined floodgate " or " separating brake/detain again " operation, making clockwise direction when power transmission shaft 1 rotates, clutch 5 on the power transmission shaft 1 is also made clockwise direction and is rotated, because two clutches 4, the direction relations of 5 sawtooth will make clutch 5 upwards rise and disconnecting clutch 4 (clutch separates automatically), after each manual operation is finished, under the effect of back-moving spring 7, clutch 5 will move downward, and keep engagement with clutch 4, for next electric operating is got ready.
Contrast Fig. 3, the boss of slide block 3 two sides, have two electrically operated institutions are carried out the effect of mechanical interlocking, can do in " duplicate supply " electric power system, two circuit breakers to be carried out mechanical interlocking, to prevent that two circuit breakers from causing the major accident of mains supply system simultaneously, the slide block that the I among Fig. 3, II are respectively two electrically operated institutions is in " combined floodgate ", " separating brake " state, by the effect of connecting rod 8, to stop slide block II to close a floodgate, vice versa.
