Definitions

  • the present invention relates to a compact circuit breaker mechanism for a switching device with, preferably, a tripolar insulating rod, which is used to deliver the output to the switching device.
  • Circuit breakers are automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliances upto large switchgear designed to protect high voltage circuits feeding an entire city.
  • the part of circuit breakers connected in one phase is called the pole and a circuit breaker suitable for three phase system is called a triple-pole circuit breaker.
  • Each pole of the circuit breaker comprises one or more interrupter or arc-extinguishing chambers.
  • the interrupters are mounted on support insulators. The interrupter encloses a set of fixed and moving contacts, the moving contacts can be drawn apart by means of operating links of the operating mechanism.
  • the operating mechanism provides the necessary energy for opening and closing of contacts of the circuit breakers.
  • US 4,001,742 discloses a circuit breaker including an operating mechanism having powerful mechanism springs to achieve the requisite contact pressures for high current carrying capacity.
  • a single crank of a rotary handle through a relatively small arc of 120° resets the operating mechanism via a reciprocating slide and a latching mechanism, while loading the mechanism springs.
  • Return of the handle to its original position shifts the line of action of the springs so as to abruptly straighten a toggle and achieve rapid closure of the circuit breaker contacts.
  • the latching mechanism is equipped with plural circuit breaker tripping capabilities.
  • US 5,731,560 discloses a mechanism for a multipole circuit breaker mechanism with high currents and high electrodynamic strength comprising a toggle device associated with a trip hook and a switching bar, an opening ratchet cooperating with the hook to perform loading and tripping of the mechanism respectively in the locked or unlocked position of the ratchet.
  • the opening ratchet comprises disengageable actuating means causing self-locking of the catch in the presence of a short circuit current exceeding a calibration threshold defined by flexible means.
  • the catch is in the shape of a half-moon to move the opening ratchet to the unlocked position to being about the tripping of the mechanism.
  • the present invention seeks to overcome the limitations mentioned above and to provide an improved compact circuit breaker mechanism
  • the circuit breaker mechanism as disclosed in this specification comprises of three sub-assemblies, namely, the pumping/charging system, the crank and connecting rod system and the contact pressure and slider system.
  • the pumping system is used to charge the main driving springs.
  • the driving springs are compression type springs mounted and guided between the shaft on which the cams are mounted (camshaft) and the frame of the mechanism such that the spring gets compressed and decompressed when the camshaft rotates.
  • the pumping or charging system is achieved by the pumping or charging system.
  • the pumping system comprises a ratchet and pawl mechanism and a set of gears and a handle mounted on the same shaft as the ratchet wheel.
  • the handle is given a downward stroke of 60° and the ratchet wheel along with the gear mounted on the ratchet shaft also turns by the same angle
  • the charging of the springs produces an opposing force which tries to discharge the stored energy which requires the camshaft and the ratchet wheel to rotate in the opposite direction than that of the handle.
  • the locking pawl blocks this rotation, thus keeping the springs charged till they cross the toggle line.
  • the cam and slider crank system are activated once the closing springs have crossed the toggle line.
  • the slider and crank system consists of two crank assemblies on either side of a latch.
  • the crank assemblies consist of two crank plates assembled with a roller and roller-pin between them, also assembled on the crank is a connecting rod with the help of a connecting pin.
  • the slider assembly consists of one slider and three assemblies of the moving contact and contact pressure spring with washers and nuts.
  • the slider being used to support the three contact pressure springs and moving contacts is made of an insulating material.
  • the assembly is so made that the contact pressure spring is assembled between two washers wherein one washer is supported by the moving contact and the other washer rests on the slider while the moving contact goes through the slider, the spring and washers and is fastened with the help of the nut.
  • the moving contact is allowed to slide in the slider. Tightening or loosening the nut (35) changes the distance between the 2 washers thereby compressing / decompressing the contact pressure spring.
  • the hexagonal apertures on the slider show where the slider rod would be assembled.
  • the compact circuit breaker mechanism of the present invention comprises: a handle assembly including a handle; a driving spring charging system comprising: at least one driving spring mounted between a camshaft and a fixed frame of the circuit breaker; motion transferring means coupled with the handle assembly and the camshaft, such that, every stroke of the handle rotates the camshaft in a direction opposite the direction of the handle rotation thereby charging said driving spring; a locking mechanism for preventing reverse direction rotation of the camshaft due to the resisting force caused by the charging driving spring; a crank and slider assembly comprising: a crankshaft; a latch mechanism assembled on said crank shaft but moving independently of said crankshaft; at least two crank assemblies assembled on said crank shaft, each on either side of said latch mechanism, each of said crank assembly including at least two crank plates coupled to each other, a connecting rod is provided such that one end of said connecting rod is slidably assembled intermediate said at least two crank plates and the other free end has provision to be assembled with a slider rod; opening spring assemblies provided at the outer sides of the crank assemblies
  • Figs 20 and 21 shows the assembly of the individual subassemblies of the contact pressure and slider system with individual insulators used on the moving contacts before the contact pressure springs.
  • Figure 1 and 2 disclose the complete operating mechanism of the circuit breaker according to this invention.
  • the parts A, B, C and D are assembled together so as to form a rigid assembly, which serves as the frame or the base for the mechanism to function.
  • These four parts in themselves do not move but serve as the support on which all other moving parts of the mechanism are assembled.
  • the complete assembly is divided into three sub-assemblies, which are explained as follows.
  • the three sub-assemblies are:
  • Figure 3 illustrates the pumping system used to charge the main driving springs 1.
  • the driving springs 1 are compression type springs mounted and guided between the shaft 2 on which the cams 3 are mounted (camshaft) and the frame of the mechanism such that the spring 1 gets compressed and decompressed when the camshaft 2 rotates.
  • the camshaft is required to be rotated. This is achieved by the pumping system as illustrated in Figure 3 .
  • the pumping system consists of a ratchet 5 and pawl 6, 7 system and a set of gears 9, 10 along with a handle 8 mounted on the same shaft as the ratchet wheel.
  • a handle 8 mounted on the same shaft as the ratchet wheel.
  • This gear 9 is always meshed with the gear 10 on the camshaft 2, such that, whenever the ratchet 5 rotates the camshaft 2 also rotates by an angle, which is dictated by the gear ratio.
  • the length of the driving springs 1 changes thereby charging /discharging it.
  • the camshaft 2 rotates in a direction, which causes the driving springs 1 to get charged. Since the driving springs 1 are being charged they produce an opposing force, which tries to discharge the stored energy. In order for the springs to discharge, the camshaft 2 and the ratchet wheel 5 have to rotate in a direction opposite to that produced by the handle 8, but the locking pawl 6 blocks this rotation thus keeping the springs 1 charged till they cross the toggle line.
  • the driving and locking pawls 7 & 6 are spring loaded so as to always remain in contact with the ratchet wheel 5.
  • the gear ratio is so chosen that 5 strokes of 60 degrees of the handle 8 (in effect 300 degrees rotation of the ratchet wheel 5) would cause a 186 degree turn of the camshaft 2 (i.e. the springs 1 would just be pushed beyond the toggle line when being charged). Once the springs 1 are beyond the toggle line they are no longer prevented from discharging as the pawls 6 & 7 no longer block the rotation of either the camshaft 2 or the ratchet 5, and the mechanism is set into motion till the driving springs 1 are completely discharged.
  • the main driving springs 1 are mounted between the camshaft 2 and the frame of the circuit breaker.
  • the fixed ends of the springs are mounted on parts such that the springs are allowed to swivel in the frame as indicated in Figure 3 .
  • the camshaft 2 has two cams 3 assembled on it in order to move two synchronized crank assemblies (described further down). Whenever the camshaft 2 rotates, the length of the driving spring 1 changes thereby charging/discharging it. Thus, in order to charge the main driving springs 1, the camshaft 2 should be rotated in the clockwise direction as shown in the figure.
  • the pumping system is used to rotate the camshaft 2.
  • the pumping system is made up of a ratchet wheel 5 and pawl 6, 7 system. And this pumping system is integrated with the camshaft 2 by the use of a gear 9 and pinion 10.
  • This gear 9 now causes the pinion 10, which is mounted on the camshaft 2, to rotate.
  • the camshaft 2 rotates and vice-versa.
  • the handle 8 is mounted on the ratchet shaft 4 such that it is free to rotate on the ratchet shaft independently. It is only when the handle moves down (clockwise direction) that the driving pawl 7 engages with the teeth of the ratchet wheel 5 and causes it to rotate through a certain angle. This rotation of the ratchet causes the camshaft 2 to also rotate through a certain angle (this angle is decided by the gear ratio) and causes the driving spring 1 to be charged. Now the spring 1 being charged will produce a resisting force causing the camshaft and in turn the ratchet to rotate in a direction opposite to that of the handle, but this action is prevented by the locking pawl 6 (which is spring mounted to always remain in contact with the ratchet wheel). Thus for every stroke of the handle the ratchet turns and in turn the camshaft turns and the driving springs are charged and the handle is returned to its initial position by the use of springs. This action is repeated till the spring is compressed till its most compressible state.
  • the spring length is the minimum possible (i.e. the spring is compressed to its maximum possible extent and thus completely charged).
  • the driving springs 1 cannot discharge by causing the cam shaft 2 to rotate in the clockwise direction.
  • the gear ratio is so chosen that the last few degrees of the last charging stroke are utilized in pushing the driving springs 1 beyond the toggle line.
  • crank and slider system is composed of various sub-assemblies. Each of these assemblies is dealt with individually below.
  • the slider and crank system without the cam and camshaft is shown in the figure-9.
  • the assembly shown in figure 9 consists of two crank assemblies 11 on either side of the latch 19.
  • the crank assemblies 11 and the latch 19 are mounted on the crank shaft 18 with spacers 17 used to keep them apart. They are assembled such that the crank assemblies 11 move together when the crank shaft 18 moves but the latch 19 is free and moves independently on the crank shaft 18.
  • crank assemblies 11 consist of two crank plates 12 assembled with a roller 14 and roller pin 13 between them. Also assembled on the crank 12 is a connecting rod 15 with the help of a connecting pin 16. The free end of the connecting rod 15 will be assembled in the slider rod 27 ( fig 11 ) with the help of a bush 20, which allows the connecting rod to rotate on the hexagonal slider rod.
  • the opening spring assembly is as shown in figure-10. It consists of an opening spring 23 (helical compression spring), which is constrained between two end plates 25 using the load and locking nuts 24 as in the case of the contact pressure spring assembly.
  • One of the end plates 25 is supported on the opening spring moving support 21, this end of the spring 23 moves the instant the breaker starts closing as the opening spring moving support 21 is assembled on the hexagonal slider rod 27 by making use of the hexagonal slot in the opening spring moving support 21.
  • the other end of the opening spring 23 is supported on the opening spring fixed support 22.
  • the opening spring fixed support 22 is firmly fixed on the frame of the breaker. Therefore, once the breaker starts closing the opening spring (23) is compressed between the moving end plate and the fixed end plate and thereby is charged.
  • the opening spring moving support (21) slides through the hole in the opening spring fixed support (22).
  • the slider assembly consists of one slider 31 and three assemblies of the moving contact 32 and contact pressure spring 33 with washers 34 and nuts 35.
  • the slider 31 being used to support the three contact pressure springs 33 and moving contacts 32 is made of an insulating material.
  • the assembly is so made that the contact pressure spring 33 is assembled between two washers wherein one washer is supported by the moving contact and the other washer rests on the slider while the moving contact goes through the slider, the spring and washers and is fastened with the help of the nut 35 as shown in the figure-12.
  • the moving contact 32 is allowed to slide in the slider 31. Tightening or loosening the nut 35 changes the distance between the 2 washers thereby compressing/decompressing the contact pressure spring 33.
  • the hexagonal apertures on the slider 31 show where the slider rod 27 would be assembled.
  • the assembly is so made the when the slider 31 moves in the direction indicated by the arrow the contact pressure springs 33 and the moving contacts 32 move as one body.
  • the slider 31 can still move as the moving contacts 32 are free to slide in the slider 31 and the contact pressure springs 33 get compressed and thus charged thereby producing the required contact pressure.
  • the moving contacts 32 also start to move with the slider 31 as if the entire assembly is one body.
  • Figure-13 shows the assembly consisting of the individual sub-assemblies discussed above.
  • the crank and connecting rod assembly, the opening spring assembly and the slider assembly are all assembled with the slider rod.
  • FIG-14 is shown the assembly, which was shown in figure-13 but with the addition of the half moon bar assembly 36, which is assembled in the frame of the circuit breaker (between plates C and D shown in figures 1 & 2 ).
  • the half moon bar 36 is a steel shaft that is split lengthwise. It is shown in greater detail in the lower part of figure-14.
  • the half moon bar 36 is spring loaded to always turn in the anticlockwise direction (indicated by the circular arrow in the figure) about the axis of rotation indicated in the figure.
  • the overlap between the latch and the half-moon bar is about 1 to 1.5mm.
  • the half moon bar 36 can only rotate through a certain angle as it has end projections that are constrained within slots in the frame (In plates C & D). It serves as a part of the latch 19 to hold the breaker in the closed position, and also to open the circuit breaker. The functioning of the half moon bar 36 is explained in the closing sequence of the circuit breaker.
  • the figure-17 shows the circuit breaker in a nearly closed position but the driving springs 1 are not completely discharged and the cam 3 is still in contact with the roller 14.
  • the slider 31 has moved further away just enough for the latch 19 (which is spring loaded) to move into place while resting against the latch roller 26.
  • the latch 19 has moved down the spring-loaded half moon bar 36 is free to rotate as the latch 19 is no longer blocking its rotation and so it rotates such that its cylindrical portion is now in contact with the latch 19 instead of the flat portion like in figure-16.
  • a gap is also formed between the nut 35 on the moving contact 32 and the slider 31 indicated by the arrows in the figure-17. This gap exists because the moving contact 32 comes into contact with the fixed contact before the slider 31 stops moving.
  • the slider 31 moves in relation to the moving contact 32 (It is to be noted that before the moving contact 32 was stopped by the fixed contact, the moving contact 32 and the slider 31 moved as if they were one body) and the contact pressure spring 33 gets compressed by the distance indicated on the figure-17 and charged. It should also be noted that the opening springs 23 are also charged while the breaker is closing as the slider 31 is moving and so is the slider rod 27 and so is the opening spring support (21 not shown in figure). The distance before contact between the moving contact 32 and a fixed contact is about 12mm.
  • This assembly consists of a slider 31 and an assembly of the moving contact 32 and contact pressure spring 33 with washers 34 and nuts 35.
  • the slider which is being used to support the contact pressure spring 33 and moving contact assembly 32, is made in the shape of a U with hexagonal cuts where the slider rod 27 is assembled.
  • the moving contact assembly 32 is made up of the insulating cap 37, the moving contact 38 and the threaded connector 39 into which fits the moving shaft of the vacuum bottle. It can be observed that the moving contact 38 and the threaded connector are embedded in the insulating cap 37 and thus are in effect one body, so whenever the moving contact 38 experiences any motion or force the same is experienced by the entire moving contact assembly 32.
  • the assembly is so made that the contact pressure spring 33 is assembled between two washers 34 wherein one washer is supported by the moving contact 38 and the other washer rests on the slider 31 while the moving contact 38 goes through the slider 31, the contact pressure spring 33 and washers 34 and is fastened with the help of the nut 35 as shown in the figure-19.
  • the moving contact 38 is allowed to slide in the slider 31. Tightening or loosening the nut 35 changes the distance between the 2 washers 34 thereby compressing/decompressing the contact pressure spring 33.
  • the hexagonal apertures on the slider show where the slider rod 27 would be assembled. The assembly is so made that when the slider moves in the direction indicated by the arrow the contact pressure springs and the moving contacts move as one body. However when the motion of the moving contact assembly 32 is restricted (by the fixed contacts in the vacuum bottle), the slider 31 can still move as the moving contact 38 is free to slide in the slider 31 and the contact pressure springs 33 get compressed and thus charged thereby producing the required contact pressure. Similarly when the slider 31 moves in a direction opposite to that indicated, initially only the slider 31 moves and once the contact pressure spring 33 discharge, the moving contact 38 also start to move with the slider (31) as if the entire assembly is one body.
  • Figure-20 shows the assembly consisting of the individual sub-assemblies discussed above.
  • the crank and connecting rod assembly, the opening spring assembly and the contact pressure spring and slider assembly all assembled on the slider rod 27.
  • the slider 31 is assembled with the opening spring support 21 inside it as shown in figures 20 and 21 .
  • Spacers 40 are utilized to keep the three contact pressure spring and slider assemblies apart at appropriate distances. This is more clearly visible in the figure-21.
  • Also assembled on the slider rod 27 are slider blocks 41 which slide in slots in the end plates of the frame (A) and (D) (from figures 1 and 2 ).
  • the latch roller 26 assembly also fits in between the slider 31 Apart from this variation the functioning (i.e. the opening and closing) of the circuit breaker remains the same.
