Description

Technical Field

[0001] This invention relates to the technical field of circuit breakers, and in particular to a circuit breaker switch. Background Technology

[0002] A circuit breaker is a device capable of closing, carrying, and interrupting current under normal circuit conditions, and capable of closing, carrying, and interrupting current under abnormal circuit conditions within a specified time. Circuit breakers are classified according to their application range, with the distinction between high and low voltage being somewhat blurred; generally, those above 3kV are considered high-voltage electrical appliances. Circuit breakers can be used to distribute electrical energy, infrequently start asynchronous motors, and protect power lines and motors. When serious overloads, short circuits, or undervoltage faults occur, they can automatically disconnect the circuit, functioning similarly to a combination of a fuse switch and over / under-temperature relays. Furthermore, generally no parts need to be replaced after interrupting a fault current. Currently, they have gained widespread application.

[0003] Chinese invention patent CN114937572A, published in related technologies, discloses a composite holding spring operation for a 66kV and above vacuum circuit breaker. The system includes a rear assembly plate, a main shaft, a dual closing energy storage assembly, a dual opening energy storage assembly, a dual buffer assembly, a closing energy storage operation assembly, and a closing / opening operation assembly. The assembly box also houses a closing drive shaft, which is located on the front side of the main shaft. The closing drive shaft is equipped with an energy storage operation gear and a clutch assembly. The energy storage operation gear is movably connected to the closing drive shaft, and the clutch assembly is located on one side of the energy storage operation gear. The clutch assembly is used to achieve power disengagement between the energy storage operation gear and the closing drive shaft. The clutch assembly includes a clutch wheel, a clutch lever, a lever shaft, and a release post. The clutch wheel is fixedly connected to the closing drive shaft. A groove is provided on the circumference of the clutch wheel. The clutch lever is mounted on the energy storage operating gear through the lever shaft. A torsion spring post is provided next to the clutch lever. A first torsion spring is mounted on the torsion spring post, and one of the legs of the first torsion spring rests on the clutch lever, so that the end of the clutch lever facing the closing drive shaft rests in the groove on the circumference of the clutch wheel. The release post is fixed to the side wall of the assembly box, and the position of the release post corresponds to the position of the end of the clutch lever away from the closing drive shaft.

[0004] Regarding the aforementioned technologies, when energy storage is completed, the clutch lever on the energy storage operating gear rotates to the position corresponding to the release column. The release column pushes the outer end of the clutch lever, causing the clutch lever to rotate and disengage from the slot on the clutch wheel. When the clutch lever disengages from the slot on the clutch wheel, it rotates towards the direction closer to the closing drive shaft under the elastic force of the first torsion spring, causing the side of the clutch lever near the closing drive shaft to abut against the outer circumferential surface of the clutch wheel. When the energy storage operating wheel drives the clutch lever to idle, there is a possibility that the clutch lever may once again press against the slot on the clutch wheel, potentially preventing the energy storage operating wheel from continuously idling. Summary of the Invention

[0005] To address the issue that when the energy storage operating wheel drives the clutch lever to spin freely, the clutch lever may become stuck in the groove on the clutch wheel again, preventing the energy storage operating wheel from spinning continuously, this application provides a circuit breaker switch.

[0006] The circuit breaker switch provided in this application adopts the following technical solution: A circuit breaker switch includes a base, an assembly box on the top surface of the base, a side plate on one side of the assembly box, a connecting pipe fixed between the side plate and the assembly box, an energy storage spring inside the connecting pipe, a first mounting cavity and a second mounting cavity inside the assembly box, a first gear and an energy storage operating wheel rotatably mounted on the inner wall of the first mounting cavity, the first gear meshing with the energy storage operating wheel, a tensioning component for compressing the energy storage spring on the first gear, a connecting component for allowing the energy storage operating wheel to idle on the first gear, and a drive mechanism for driving the energy storage operating wheel to rotate on the assembly box.

[0007] By adopting the above technical solution, when the drive mechanism drives the energy storage operating wheel to rotate, the energy storage operating wheel drives the first gear to rotate. When the first gear rotates at a certain angle, the tension component on the first gear pulls the energy storage spring to compress the stored energy. The connecting component on the first gear rotates to the position of the energy storage operating wheel, causing the energy storage operating wheel to continuously idle, thereby reducing the possibility that the energy storage operating wheel cannot continuously idle when the energy storage spring compresses the stored energy.

[0008] Preferably, the tensioning assembly includes a push plate slidably disposed within the connecting tube, the push plate being located on the side of the energy storage spring away from the assembly box, a pull rod being fixed to the side of the push plate near the assembly box, a displacement hole being provided on the side of the assembly box near the side plate, the end of the pull rod away from the push plate passing sequentially through the energy storage spring and the displacement hole, an eccentric shaft being fixed to the side of the first gear, and the end of the pull rod away from the push plate being rotatably mounted on the outer circumferential surface of the eccentric shaft.

[0009] By adopting the above technical solution, when the energy storage operating wheel rotates and drives the first gear to rotate, the first gear drives the eccentric shaft to rotate, the eccentric shaft drives the pull rod to move, and the pull rod drives the push plate to move towards the first gear, thereby causing the push plate to push the energy storage spring to compress and store energy.

[0010] Preferably, the driving mechanism includes a rotating shaft 1 rotatably mounted on the opposite inner surfaces of the mounting cavity 2, the rotating shaft 1 being rotatably connected to the assembly box, the energy storage operating wheel being fixed to one end of the rotating shaft 1, a transmission gear 1 being provided on the outer circumferential surface of the rotating shaft 1, a rotating shaft 2 rotatably mounted on the opposite inner surfaces of the mounting cavity 2, a transmission gear 2 being provided on the rotating shaft 2, the transmission gear 1 meshing with the transmission gear 2, and a driving assembly for driving the rotating shaft 2 to rotate being provided on the assembly box.

[0011] By adopting the above technical solution, the drive component is started, the drive component drives the second rotating shaft to rotate, the second rotating shaft drives the second transmission gear to rotate, the second transmission gear drives the first transmission gear to rotate, the first transmission gear drives the first rotating shaft to rotate, the first rotating shaft drives the energy storage operating wheel to rotate, thereby causing the energy storage operating wheel to drive the first gear to rotate.

[0012] Preferably, the drive assembly includes a motor disposed on the inner wall of the second mounting cavity, a drive gear disposed on the output shaft of the motor, and a driven gear disposed on the second rotating shaft, wherein the drive gear meshes with the driven gear.

[0013] By adopting the above technical solution, the motor is started, and the output shaft of the motor drives the driving gear to rotate. The driving gear drives the driven gear to rotate, thereby causing the driven gear to drive the rotating shaft to rotate.

[0014] Preferably, the outer peripheral surface of the first gear has a groove, and the connecting assembly includes an incomplete gear rotatably disposed in the groove. A first spring is fixed to the side of the incomplete gear near the central axis of the first gear, and the end of the first spring away from the incomplete gear is fixed to the inner side of the groove near the central axis of the first gear.

[0015] By adopting the above technical solution, when the energy storage operating wheel rotates, it drives the first gear to rotate, which in turn drives the eccentric shaft to rotate. The eccentric shaft drives the pull rod to move, which in turn drives the push plate to move closer to the first gear. This causes the push plate to compress the energy storage spring. When the energy storage operating wheel drives the first gear to rotate and move by an angle, the groove moves to the position of the energy storage operating wheel, allowing the energy storage operating wheel to mesh with the incomplete gear. When the energy storage operating wheel rotates, it drives the incomplete gear to rotate, causing the incomplete gear to rotate towards the groove. The first spring is in a compressed state. When the incomplete gear disengages from the energy storage operating wheel, it moves closer to the energy storage operating wheel under the elastic force of the first spring, causing the incomplete gear to reciprocate and mesh with the energy storage operating wheel. Thus, when the energy storage spring is compressed to store energy, the energy storage operating wheel continuously spins.

[0016] Preferably, a limiting rod is fixed to the opposite inner side of the groove, and a limiting block is fixed to the side wall of the incomplete gear. The side of the limiting block away from the central axis of the first gear can abut against the outer peripheral surface of the limiting rod.

[0017] By adopting the above technical solution, when the incomplete gear moves toward the direction closer to the first gear under the elastic force of the first spring, the limiting block abuts against the limiting rod, thereby reducing the possibility that the incomplete gear will move toward the direction closer to the energy storage operating wheel under the elastic force of the first spring and move out of the groove.

[0018] Preferably, a limiting post is fixed to the side of the first gear, an installation rod is fixed to the inner side of the first mounting cavity, a positioning rod is sleeved on the outer circumferential surface of the installation rod, the positioning rod is rotatably connected to the installation rod, and a slot is opened on the end face of the positioning rod, into which the limiting post can be inserted.

[0019] By adopting the above technical solution, when the first gear rotates, the first gear drives the limiting post to move. After the energy storage spring is compressed and stores energy, the limiting post moves into the slot, thereby reducing the possibility of the first gear reversing under the elastic force of the energy storage spring.

[0020] Preferably, a stop block is fixed on the inner wall of the mounting cavity, a drive rod is fixed on the bottom surface of the positioning rod, a second spring is provided between the drive rod and the stop block, a mounting groove is provided on the side of the drive rod near the stop block, one end of the second spring is provided in the mounting groove, a guide post is provided on the side of the stop block away from the drive rod, the guide post is threadedly connected to the stop block, and the second spring is sleeved on the periphery of the guide post.

[0021] By adopting the above technical solution, when the limiting post moves into the slot, the drive rod rotates away from the baffle under the elastic force of the second spring, causing the drive rod to drive the positioning rod to rotate, so that the limiting post is locked in the slot, thereby reducing the possibility of the limiting post coming out of the slot.

[0022] Preferably, the base has an arc-extinguishing chamber on its side and a contact switch connected to the arc-extinguishing chamber on its inner side. A partition is fixed to the inner top surface of the base, and a drive shaft passes through the side of the partition. The drive shaft is rotatably connected to the partition. A first swing arm is mounted on the drive shaft. The end of the contact switch away from the arc-extinguishing chamber is hinged to the bottom end of the first swing arm. A through hole is opened on the top surface of the base, and a connecting rod passes through the through hole. The outer circumferential surface of the connecting rod is spaced apart from the inner circumferential surface of the through hole. A second swing arm is mounted on the drive shaft. The bottom end of the connecting rod is hinged to the end of the second swing arm away from the drive shaft. A driving component for driving the connecting rod to move vertically is mounted on the first gear.

[0023] By adopting the above technical solution, when the energy storage spring is compressed and energy needs to be stored, the drive rod is moved towards the stop block, causing the drive rod to rotate and the positioning rod to disengage the limit post from the slot. The first gear rotates in the opposite direction under the elastic force of the energy storage spring, causing the first gear to drive the drive component to move. The drive component then drives the connecting rod to move downward. When the connecting rod moves downward, it drives the second swing arm to rotate. The second swing arm drives the rotating shaft to rotate, and the rotating shaft drives the first swing arm to rotate. The first swing arm drives the switch contact to move towards the arc-extinguishing chamber, thereby completing the closing operation.

[0024] Preferably, a rotating shaft three is provided on the inner side wall of the assembly box, the first gear is fixed on the rotating shaft three, the rotating shaft three is rotatably connected to the assembly box, the driving component includes a cam provided on the rotating shaft three, a rotating shaft four is rotatably installed between the opposite inner sides of the mounting cavity two, a swing arm three is provided on the rotating shaft four, a roller is rotatably installed at the top end of the swing arm three, the outer peripheral surface of the cam can abut against the outer peripheral surface of the roller, the swing arm four is provided on the rotating shaft four, and the top end of the connecting rod is hinged to the end of the swing arm four away from the rotating shaft four.

[0025] By adopting the above technical solution, when the first gear rotates in the opposite direction under the force of the energy storage spring, the first gear drives the rotating shaft three to rotate, the rotating shaft three drives the cam to rotate, and the cam drives the swing arm three to rotate upward during the rotation process, so that the swing arm three drives the rotating shaft four to rotate, the rotating shaft four drives the swing arm four to rotate downward, thereby causing the swing arm four to drive the connecting rod to move downward.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. When the drive mechanism drives the energy storage operating wheel to rotate, the energy storage operating wheel drives the first gear to rotate. When the first gear rotates at a certain angle, the tension component on the first gear pulls the energy storage spring to compress the stored energy. The connecting component on the first gear rotates to the position of the energy storage operating wheel, so that the energy storage operating wheel can continuously spin freely, thereby reducing the possibility that the energy storage operating wheel cannot continuously spin freely when the energy storage spring compresses the stored energy. 2. When the energy storage operating wheel rotates, it drives the first gear to rotate, which in turn drives the eccentric shaft to rotate. The eccentric shaft drives the pull rod to move, which in turn drives the push plate to move closer to the first gear. This causes the push plate to compress the energy storage spring. When the energy storage operating wheel drives the first gear to rotate and move by an angle, the groove moves to the position of the energy storage operating wheel, causing the energy storage operating wheel to mesh with the incomplete gear. When the energy storage operating wheel rotates, it drives the incomplete gear to rotate, causing the incomplete gear to rotate towards the groove. The first spring is in a compressed state. When the incomplete gear disengages from the energy storage operating wheel, it moves closer to the energy storage operating wheel under the elastic force of the first spring, causing the incomplete gear to reciprocate and mesh with the energy storage operating wheel. Thus, when the energy storage spring is compressed to store energy, the energy storage operating wheel will continuously spin freely. 3. When the energy storage spring is compressed and energy is stored, and closing the circuit is required, the drive rod is moved towards the stop block, causing the drive rod to rotate and the positioning rod to rotate, causing the limit pin to disengage from the slot. The first gear rotates in the opposite direction under the elastic force of the energy storage spring, causing the first gear to drive the drive component to move, which in turn drives the connecting rod to move downward. When the connecting rod moves downward, it drives the second swing arm to rotate, which in turn drives the rotating shaft to rotate. The rotating shaft then drives the first swing arm to rotate, causing the first swing arm to drive the switch contact to move towards the arc-extinguishing chamber, thus completing the closing operation.

[0050] The implementation principle of a circuit breaker switch according to an embodiment of this application is as follows: When performing closing energy storage, energy storage can be performed manually or electrically. When performing manual energy storage, the handle 52 is moved toward the direction of the first gear 31. The handle 52 drives the rotating shaft 51 to move toward the direction of the first gear 31. The rotating shaft 51 drives the drive plate 53 to move toward the direction of the first gear 31, so that the moving column 55 is inserted into the insertion slot 54. Then, the handle 52 is rotated, which drives the rotating shaft 51 to rotate. The rotating shaft 51 drives the drive rod 65 to rotate, which drives the moving column 55 to rotate. The moving column 55 drives the first gear 31 to rotate. The eccentric shaft 32 on the first gear 31 drives the pull rod 23 to move, which drives the push plate 22 to move, which compresses the energy storage spring 21, thus compressing the energy storage spring 21 to store energy. When the first gear 31 rotates, it also drives the limiting post 63 to move, so that the limiting post 63 is locked in the slot 62, thereby reducing the possibility that the first gear 31 will reverse under the elastic force of the energy storage spring 21 after the energy storage spring 21 is compressed and the handle 52 is released.

[0051] When electric energy storage is used, starting the motor 43 causes the output shaft of the motor 43 to drive the drive gear 44 to rotate. The drive gear 44 drives the driven gear 45 to rotate, which in turn drives the rotating shaft 42 to rotate. The rotating shaft 42 drives the transmission gear 41 to rotate, which in turn drives the rotating shaft 33 to rotate. This causes the rotating shaft 33 to drive the energy storage operating wheel 34 to rotate. The energy storage operating wheel 34 drives the first gear 31 to rotate, which in turn drives the eccentric shaft 32 to rotate. The eccentric shaft 32 then moves the pull rod 23, causing the pull rod 23 to move the push plate 22 towards the first gear 31, thus compressing the energy storage spring 21 to store energy. When the energy storage spring 21 has fully compressed and stored energy... When the first gear 31 is completed, the limiting post 63 on the first gear 31 is engaged in the slot 62, and the groove 35 on the first gear 31 moves to the position of the energy storage operating wheel 34, so that the energy storage operating wheel 34 meshes with the incomplete gear 36. When the energy storage operating wheel 34 rotates, the energy storage operating wheel 34 drives the incomplete gear 36 to rotate, so that the incomplete gear 36 rotates toward the groove 35. The first spring 37 is in a compressed state. When the incomplete gear 36 disengages from the energy storage operating wheel 34, the incomplete gear 36 moves toward the direction closer to the energy storage operating wheel 34 under the elastic force of the first spring 37, so that the incomplete gear 36 reciprocates to mesh with the energy storage operating wheel 34. Thus, when the energy storage spring 21 has completed the compression and energy storage, the energy storage operating wheel 34 will continuously rotate.

[0052] When closing the circuit breaker, rotating the second handle 72 causes the second rotating shaft 7 to rotate, which in turn causes the first lever 71 to rotate. This causes the first lever 71 to move the drive rod 65 upward, disengaging the limit pin 63 from the slot 62. The first gear 31, under the force of the energy storage spring 21, reverses direction, causing the first gear 31 to drive the third rotating shaft 3 to rotate. The third rotating shaft 3 then causes the cam 93 to rotate towards the swing arm 91, driving the swing arm 91 upward. Simultaneously... The limiting wheel 99 on the swing arm 3 91 is engaged in the limiting groove 98. The swing arm 3 91 drives the rotating shaft 4 9 to rotate, which in turn drives the swing arm 4 1101 to rotate upward. This causes the swing arm 4 1101 to move the connecting rod 86 upward, which in turn drives the swing arm 2 87 to rotate upward. The swing arm 2 87 then drives the transmission shaft 83 to rotate, which in turn drives the swing arm 1 84 to rotate towards the arc-extinguishing chamber 8. This causes the swing arm 1 84 to drive the contact switch 81 to move, achieving synchronous closing. When closing is complete, the swing arm 5 1102 pulls the connecting shaft 1108 towards the rotating shaft 4 9, which in turn pulls the pull plate 1106 towards the rotating shaft 4 9. This causes the pull plate 1106 to stretch the opening spring 1107, completing the automatic energy storage of the opening spring 1107.

[0053] When tripping is required, the positioning block 95 is moved upwards, causing the limit wheel 99 to disengage from the limit groove 98. The tripping spring 1107 contracts under the action of its elastic force, causing the tripping spring 1107 to pull the pull plate 1106 away from the rotating shaft 9. The pull plate 1106 drives the connecting shaft 1108 away from the rotating shaft 9, causing the connecting shaft 1108 to drive the swing arm 1102 to rotate. The swing arm 1102 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the swing arm 1101 to rotate downwards. The swing arm 1101 drives the connecting rod 86 to move downwards, causing the connecting rod 86 to drive the swing arm 87 to rotate downwards. The swing arm 87 drives the transmission shaft 83 to rotate, causing the transmission shaft 83 to drive the swing arm 84 away from the arc-extinguishing chamber 8. The swing arm 84 drives the contact switch 81 away from the arc-extinguishing chamber 8, thereby realizing the tripping operation.
