When the present invention is used, for the direction being previously mentioned in the present invention be all to correspond to direction shown in Figure of description and Speech, circuit breaker internal also has many structures, and the present invention is just no longer described herein, and breaker has been prior art, its internal structure Also it is known technology, and nor improvement of the invention, therefore, the present invention in circuit breaker internal structure just for doing improvement And elaborate in the case of not influenceing the complete use of breaker, and illustrate its operation principle.
Drawn structure size there may be error in description of the invention accompanying drawing, but not influence arrangement works of the invention former Reason, such as Size Error of drawn motor.
Specific embodiment, package unit of the invention is fixed on cable bar 66, when using, start button 2 is pressed downwards Pressure, starting bar 3 follows start button 2 to move down, and now, the contact board 4 of the side of starting bar 3 drives moving contact 5 to transport downwards It is dynamic, and fixed contact 6 is contacted, now moving contact 5 is connected with fixed contact 6, and killer switch is connected, and breaker starts normally Work, when being moved downward with starting bar 3, the button pin 7 on starting bar 3 presses one end of rotor plate 8, and rotor plate 8 is around thick stick Bar 9 is rotated, and the other end of rotor plate 8 is slowly lifted up, and the other end of rotor plate 8 withstands clamp 101 and moves upwards, final arc Shape draw-in groove 11 moves to the upper end of clamp 101, and when start button 2 is pressed into lowermost end, arc-shaped slot 11 is stopped by clamp 101 Cannot return, realize that start button 2 is pressed down, the structure of normal operation of circuit breaker.
For the accurate and convenient pressing of the orientation for being further ensured that start button 2, the first elliptical aperture is provided with rotor plate 8 57, facilitate button pin 7 to be slided in the first elliptical aperture 57.
The structure of manual cut-off breaker, presses down on cut-off push button 12, and trip arm 13 follows cut-off push button 12 to transport downwards Dynamic, now, the first spring 118 is compressed, when the first spring 118 is compressed to the limit or cut-off push button 12 touches pressing During plate 14, pressing plate 14 follows cut-off push button 12 to move downward, and when top board 15 touches the termination of swing arm 16, top board 15 is opened Beginning is pressed down against swing arm 16, and swing arm 16 is rotated around swing arm axle 18, and the other end of swing arm 16 is upturned, and drives Clamp 101 is rotated counterclockwise, and finally realizes that clamp 101 departs from from arc-shaped slot 11, after loosing one's grip, due to the first spring 118 Compression, cut-off push button 1 is shot back and is returned to original position, and due to the effect of swing arm spring 19, swing arm 16 is shot back reply To original position.
In the process, for the vertical positioning to trip arm 13, there is vertical second elliptical aperture 58 on top board 15, it is and disconnected The orienting pin 59 of the connection of opening lever 13 is slided in the second elliptical aperture 58 and realizes orientation.
Rocking lever backing pin 17 can effectively prevent the right-hand member of swing arm 16 from dropping downwards, start so as to avoid clamp 101 The lower section of arc-shaped slot 11 is at during state, practical significance is otherwise just lost, the effect of rocking lever backing pin 17 is exactly to be When just state is started, arc-shaped slot 11 is contacted with clamp 101, and is between clamp 101, thus can be protected Card, during started by press button 2, arc-shaped slot 11 is moved upwards, is stopped by clamp 101, during pressing cut-off push button 12, clamp 101 Depart from from arc-shaped slot 11 and be returned to original position, because the presence of swing arm backing pin 17 and the effect opened can not be ignored, it is The necessary condition for starting and disconnecting can precisely be realized.
When clamp 101 departs from arc-shaped slot 11, due to the effect of torsion spring 10, lever 9 starts to realize resetting, therefore drives Arc-shaped slot 11 is moved downward, and starting bar 3 is moved upwards, drives start button 2 to be returned to original position, now moving contact 5 with it is solid Fixed contact 6 is disengaged so that breaker disconnects.
Above describe the manually opened of breaker and the operation principle for disconnecting, and when current is excessive, breaker it is double Sheet metal occurs corresponding action, and traditional bimetal leaf concept is:
Bimetal leaf is had a kind of composite wood that the metal or other materials of suitable performance constituted by two or more Material.Bimetal leaf is also referred to as thrermostatic bimetal-plate, because the thermal coefficient of expansion of each constituent element layer is different, when the temperature is changed, active layers Deformation more than passive layer deformation so that the entirety of bimetal leaf will bend to passive one layer, then the song of this composite Rate changes so as to produce deformation, wherein, the coefficient of expansion referred to as active layers higher, the coefficient of expansion is relatively low to be referred to as passively Layer.But the progress of the expansion and combination technology with bimetallic application field, modern age mutually occurs three layers, four layers, five layers Bimetallic.In fact, every temperature dependent changes and the combined material of change in shape occurs, now traditionally still referred to as hot double Metal.
Conducting slip ring belongs to electrical contact and is slidably connected application category, and it is electric also known as collector ring or rotary joint, rotation Interface, slip ring, collecting ring, coil, commutator, adapter, are to realize two images of relative rotation mechanism, data-signal and move The accurate power transmitting device of power transmission.Unconfined continuous rotation is particularly suitable for, while need to be transmitted from fixed position again The place of power or data.
Bimetal leaf is established as bimetallic axle 21 by the present invention, and the structure of bimetallic axle 21 exists for two semicolumn metal composites Together, one end of bimetallic axle 21 is socketed with conducting slip ring 23, and the other end connects the first motor 26, the first motor through insulating disc 24 26 is in running order all the time, drives bimetallic axle 21 to rotate, due to being cased with heating wires 22 on bimetallic axle 21, for detecting Electric current is excessive, but in order to prevent the heating wires 22 from can wind fracture when rotating, therefore conducting slip ring 23 can be with effectively Heating wires 22 are prevented to be broken, and after the heat distortion of bimetallic axle 21, whether which end deformation, due to bimetallic axle 21 1 Rotary state is directly in, bimetallic top board 20 can be touched all the time, so that bimetallic top board 20 is popped up, heavier is double Metal shaft 21 is in rotary state, and when bimetallic top board 20 is touched after deformation, the power applied to it can be far longer than and slowly become The power that shape is applied, can rapidly touch and upspring bimetallic top board 20.
Bimetallic axle 21 of the invention is also different different from bimetal leaf, being played a part of, in collision process Equivalent to the addition of an active force, the effect of the bimetallic top board 20 that can quickly upspring is realized.
After bimetallic top board 20 is upspring, the right-hand member of swing arm 16 is driven to be rotated up, now clamp 101 turns counterclockwise It is dynamic slowly to depart from arc-shaped slot 11, after clamp 101 departs from arc-shaped slot 11, in the presence of torsion spring 10, arc-shaped slot 11 Rotate counterclockwise, starting bar 3 is returned to original position, so that moving contact 5 disconnects with fixed contact 6, realize the safety guarantor of breaker Shield.
When bimetallic top board 20 does not disconnect, the first cylindrical cam 29 is rotated, and the second cylindrical cam 30 is not rotated, now, the One roller 28 is realized moving up and down under the rotation of the first cylindrical cam 29, so that briquetting 38 ceaselessly realizes bob, But, the double control switch 40 of the top of briquetting 38 is not touched now, once after bimetallic top board 20 is upspring, the company of drive Rope 36 pulls metal frame 35 to move upwards and contacted with electromagnet 33 on slide rail 34, and now metal frame 35 is inhaled by electromagnet 33 Draw, the first cylindrical cam 29 is connected as one with the second cylindrical cam 30, the first cylindrical cam 29 is same with the second cylindrical cam 30 When rotate, now, due to the effect of the second roller 32, in the presence of original first cylindrical cam 29, the stroke of briquetting 38 It is the stroke of the difference between high and low of the first cylindrical cam 29, when the first cylindrical cam 29 and the second cylindrical cam 30 are rotated simultaneously, presses The stroke of briquetting 38 will become big, because 32 pairs of the second cylindrical cams 30 of the second roller also have stroke, in addition, in order to prevent first When cylindrical cam 29 is combined with the second cylindrical cam 30, lucky peak contacts minimum point, then now stroke may not increase Plus, so height of the height of the second cylindrical cam 30 higher than the first cylindrical cam 29, no matter therefore the first cylindrical cam 29 with When second cylindrical cam 30 is with which kind of combinations of states, the combination of the second cylindrical cam 30 and the second roller 32 can all give briquetting 38 Increase stroke, so that briquetting 38 touches double control switch 40.
This structure is equally emphasis of the invention, very important, and is closely connected with bimetallic top board 20, and the One cylindrical cam 29 is very ingenious with the mode that the second cylindrical cam 30 is connected, and can cleverly increase the stroke of briquetting 38, but What is needed is but the angle of very little, and need not very inside wide-angle, and the first cylindrical cam 29 and the second cylindrical cam 30 Combination it is also very ingenious, realize independent first cylindrical cam 29 rotate and the first cylindrical cam 29 and the second cylindrical cam 30 simultaneously Rotate, and obtain unexpected effect.
Now, a kind of situation is further encountered, is exactly that briquetting 38 is ceaselessly beated, after the second motor 39 starts, if Reciprocal bounce can then realize that the second motor 39 ceaselessly starts and closes, therefore it is that double control switchs 40 that briquetting 38 touches, When the first time of briquetting 38 double control switch 40 is touched, double control switch 40 starts the second motor 39 and works, and controls Electromagnet 33 is powered off, so that metal frame 35 departs from electromagnet 33, metal frame 35 is returned to original position along slide rail 34, so that first The cylindrical cam 30 of cylindrical cam 29 and second departs from again, and the first cylindrical cam 29 is rotated, the second cylindrical cam 30 is not rotated, pressing The stroke of block 38 is returned to original stroke, therefore, when briquetting 38 is beated again, double control switch 40 will not be touched, from And realize the second motor 39 and keep work.
After second motor 39 starts, bevel gear set 42 is driven to rotate through the 3rd rotating shaft 41, then driven through the 4th rotating shaft 43 Driving wheel 51 is rotated, and driving wheel 51 drives the 3rd collar 49 of the integrally connected of driving pin 50 to be moved up and down on the 3rd cylindrical bar 48 And swing, the 3rd cylindrical bar 48 drives the second cylindrical bar 46 to be swung on the first cylindrical bar 45 through the second connecting plate 47, the first circle Mast 45 is motionless, while the second cylindrical bar 46 is rotated, drives the 4th cylindrical bar 53 to swing through the 3rd connecting plate 52, supports Frame 54 controls the two ends of the 4th cylindrical bar 53 to swing, and now the swing ball 55 of the termination of the 4th cylindrical bar 53 beats the gong of both sides Plate 56 so as to send alarm, so as to tell workman section herein, line failure.
It is relatively more for circuit on cable bar 66, and winding is complicated, when there is electric current and cross major break down, it is not known which Section circuit there occurs failure, will be pretty troublesome in maintenance, wastes substantial amounts of time and goes to check the position of faulty line, and this hair It is bright to add multiple breakers in long transmission line, so when implementing, once there is fault, there are multiple circuits in other words Failure, can accurately know the position of failure circuit, and in traditional circuit, even if finding a circuit event Barrier, but if many places failure, then only overhaul and other faulty circuits for overhauling whole circuit again position has been also needed at one Put, bring very big inconvenience.
