Description

Technical Field

[0001] The invention relates to the technical field of anti-jumping of vacuum circuit breakers, and in particular to an anti-jumping column-mounted vacuum circuit breaker. Background Art

[0002] "Vacuum circuit breaker" is named because its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum; it has the advantages of small size, light weight, suitable for frequent operation, and no need for maintenance after arc extinguishing, and is widely used in distribution networks.

[0003] Pole-mounted vacuum circuit breakers are generally installed at higher locations such as electric poles. Due to their location, they require auxiliary equipment to access, which makes daily operation inconvenient. Therefore, pole-mounted vacuum circuit breakers are generally equipped with a remote control system to remotely drive the circuit breaker to open and close. If the opening and closing signal reception is abnormal, the circuit breaker repeatedly receives the opening and closing signal, which will cause the vacuum circuit breaker to jump, that is, the circuit breaker switch is repeatedly opened and closed, thereby causing great damage to the circuit breaker body and the connection of the line. Summary of the invention

[0004] The present invention discloses an anti-jumping pole-mounted vacuum circuit breaker, which aims to solve the technical problem that if an abnormality occurs in the reception of an opening and closing signal, the circuit breaker repeatedly receives the opening and closing signal, which will cause the vacuum circuit breaker to jump, that is, the circuit breaker switch is repeatedly opened and closed, thereby causing great damage to the circuit breaker body and the connection of the line.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A column-mounted vacuum circuit breaker with anti-jumping, comprising a circuit breaker body, the circuit breaker body comprising a circuit breaker switch, and the circuit breaker switch is externally connected with a coupling mechanism, two circular support plates are movably connected to the opposite sides of the circuit breaker switch through a first support shaft, and the outer walls of the same side of the two circular support plates are respectively fixedly connected to two side support rods, and the inner walls of the opposite sides of the two side support rods are respectively connected to the coupling mechanism through connecting rods, the center of the circular support plate coincides with the rotation axis of the circuit breaker switch, one side of the circular support plates is connected with a traction mechanism, and the traction mechanism is used to drive the circular support plate to rotate, and the outer side of the other circular support plate is connected with a displacement sensor, and the displacement sensor is used to sense the rotation state of the circular support plate; the traction mechanism comprises a first gear and a second gear, the first gear is fixed to the outer wall of the circular support plate, and one side of the second gear is connected to a first motor through a second support shaft.

[0007] The anti-jump structure is formed by connecting the traction mechanism with the circuit breaker switch through the connecting mechanism, wherein when the displacement sensor receives the repeated jumps of the circuit breaker switch through the abnormal rotation of the circular support plate, the circuit breaker switch can be effectively limited by the traction mechanism, so that the small motor in the circuit breaker body for controlling the opening and closing of the circuit breaker switch receives resistance and stops operating. Under this structure, in addition to the jump braking of the vacuum circuit breaker, a remote control structure can be provided again to remotely control the opening and closing of the circuit breaker through the rotation of the first motor, thereby providing time for maintenance work by providing a backup plan.

[0008] In a preferred solution, an outer support frame is fixedly provided on the outer wall of the circuit breaker body, and a connecting mechanism and a traction mechanism are both arranged in the outer support frame, a base is fixedly connected to the inner wall of the bottom end of the outer support frame, and the traction mechanism is arranged on the base, the connecting mechanism includes a linkage bracket, and a plurality of U-shaped brackets are equidistantly connected to the outer wall of one side of the linkage bracket, a hinge groove is provided at one end of each of the U-shaped brackets, a pressure rod is hinged in each of the hinge grooves, a convex rod is fixedly connected to one side of each of the pressure rods, and a first support plate is connected to one side of the convex rod by a hinge, a gas rod is fixedly connected to one side of the first support plate, and the outer side of the gas rod is fixed to the linkage bracket by a mounting frame, a pressure port is provided at the other end of each of the U-shaped brackets, and the tail end of each pressure rod is pressed into the pressure port respectively, and the connecting rod is fixed to the outer side of the U-shaped bracket located at both ends.

[0009] By providing a connecting mechanism, the connecting mechanism passes through multiple slots of the circuit breaker switch through multiple U-shaped brackets, and is closed by driving one end of the pressure rod to be pressed into the pressure slot, thereby forming a complete connection between the connecting mechanism and the circuit breaker switch. Under this structure, it is more convenient to connect the anti-jumping overall structure with the circuit breaker switch. At the same time, when the reverse operation is performed, when the multiple pressure rods are opened and the side support rods are driven to rotate in the opposite direction through the traction mechanism, the remote self-disconnection of the connecting mechanism and the circuit breaker switch can also be achieved.

[0010] In a preferred embodiment, the traction mechanism also includes a support frame, and a pull rope is fixedly connected to the middle position of the support frame, the upper part of the support frame is movably connected to the second support plate, and the top end of the second support plate is fixedly connected to the bearing seat, the second support shaft is connected to the bearing seat, and the top end of the second support plate is symmetrically fixedly connected to a plurality of limit rods, each of the limit rods is respectively surrounded by a spring, and the two ends of each spring are respectively connected to the inner wall of the support frame and the top end of the second support plate, the top end of the support frame is penetrated by a plurality of through holes, and the plurality of limit rods are respectively correspondingly inserted into the plurality of through holes, the inner walls on the opposite sides of the support frame are respectively fixedly connected to L-shaped limit frames, and the middle position of the support frame is fixedly connected to a partition, the lower half of the support frame is movably connected to a winding rod, and a pull rope is wrapped around the winding rod, one end of the pull rope is fixed to the bottom end of the second support plate, and one end of the winding rod is fixedly connected to the second motor.

At this time, the first gear and the second gear are disengaged, and the circuit breaker switch can be adjusted according to the remote opening and closing control of the circuit breaker body. When the displacement sensor detects an abnormal jump, as the winding rod is quickly relaxed, the second support plate can be driven to move up under the action of the spring until the first gear and the second gear are meshed during the rotation process. Under this structure, damage to the first motor during daily opening and closing can be avoided, thereby extending the service life of the first motor.

Under this structure, in addition to the jump braking of the vacuum circuit breaker, a remote control structure can be provided again, and the opening and closing of the circuit breaker can be remotely controlled by the rotation of the first motor 703, so as to provide time for maintenance work by providing a backup plan.

[0026] Reference Figure 3 and Figure 4 In a preferred embodiment, a pressing opening 608 is provided at the other end of each U-shaped bracket 609, and the tail end of each pressing rod 607 is pressed into the pressing opening 608 respectively, and the connecting rod 12 is fixed to the outer side of the U-shaped bracket 609 at both ends. The connecting mechanism 6 passes through the multiple notches of the circuit breaker switch 4 through multiple U-shaped brackets 609, and drives the first support plate 604 forward through the gas rod 601, and changes the angle of the protruding rod 606 to drive one end of the pressing rod 607 to press into the pressing opening 608 to complete the closure, thereby forming a complete connection between the connecting mechanism 6 and the circuit breaker switch 4. During the traction process of the traction mechanism 7, it can be ensured that the circuit breaker switch 4 will not be detached. Under this structure, it is more convenient to connect the overall anti-jump structure with the circuit breaker switch 4. At the same time, when the reverse operation is performed, the multiple pressing rods 607 are opened and the side support rods 11 are driven to rotate in the opposite direction through the traction mechanism 7, so that the remote self-detachment of the connecting mechanism 6 and the circuit breaker switch 4 can also be achieved.

[0027] Reference Figure 5 and Figure 6 In a preferred embodiment, the traction mechanism 7 also includes a support frame 709, and a pull rope 708 is fixedly connected to the middle position of the support frame 709, and the upper part of the support frame 709 is movably connected to a second support plate 715, and the top of the second support plate 715 is fixedly connected to a bearing seat 704.

[0028] Reference Figure 5 and Figure 6 In a preferred embodiment, the second support shaft 714 is connected to the bearing seat 704, and the top of the second support plate 715 is symmetrically fixedly connected with multiple limiting rods 712, each limiting rod 712 is surrounded by a spring 713, and the two ends of each spring 713 are respectively connected to the inner wall of the support frame 709 and the top of the second support plate 715.

[0029] Reference Figure 5 and Figure 6 In a preferred embodiment, a plurality of through holes 711 are penetrated through the top of the support frame 709, and a plurality of limit rods 712 are respectively inserted into the plurality of through holes 711, and L-shaped limit frames 710 are respectively fixedly connected to the inner walls on opposite sides of the support frame 709, and a partition 706 is fixedly connected to the middle position of the support frame 709.

[0030] Reference Figure 5 and Figure 6 In a preferred embodiment, the lower half of the support frame 709 is movably connected with a winding rod 707, and a pull rope 708 is wound around the winding rod 707. One end of the pull rope 708 is fixed to the bottom end of the second support plate 715, and one end of the winding rod 707 is fixedly connected to the second motor 705. The rotation of the circular support plate 10 is driven by the first motor 703 to drive the second gear 702 and the first gear 701 to rotate. Therefore, when the first gear 701 and the second gear 702 are separated, the circuit breaker switch 4 can be separated from the traction limit of the traction mechanism 7. When the circuit breaker is in normal use, the second motor 705 drives the winding rod 707 to rotate, further driving the pull rope 708 to be recovered, thereby driving the second support plate 715. When the first gear 701 moves downward, the spring 713 stretches. At this time, the first gear 701 and the second gear 702 are disengaged. The circuit breaker switch 4 can be adjusted with the remote opening and closing control of the circuit breaker body 2. When the displacement sensor 8 detects an abnormal jump, as the winding rod 707 is quickly relaxed, the second support plate 715 can be driven to move upward under the action of the spring 713 until the first gear 701 and the second gear 702 are engaged during the rotation process, and the rotation of the circular support plate 10 is limited, so that the small motor inside the circuit breaker body 2 that drives the opening and closing of the switch stops rotating, thereby completing the traction limit of the traction mechanism 7. Under this structure, damage to the first motor 703 during daily opening and closing can be avoided, and the service life of the first motor 703 can be extended.

[0031] Working principle: When in use, the traction mechanism 7 is connected to the circuit breaker switch 4 through the connecting mechanism 6 to form an anti-jump structure, wherein, when the displacement sensor 8 receives the repeated jumps of the circuit breaker switch 4 through the abnormal rotation of the circular support plate 10, the circuit breaker switch 4 can be effectively limited by the traction mechanism 7, that is, the first gear 701 is limited by the second gear 702 through the braking of the first motor 703, and the circuit breaker switch 4 is limited and pulled through the transmission of the side support rod 11 and the connecting rod 12, so that the small motor in the circuit breaker body 2 for controlling the opening and closing of the circuit breaker switch 4 receives resistance and stops operating. Under this structure, in addition to the jumping braking of the vacuum circuit breaker, a remote control structure can be provided again, and the opening and closing of the circuit breaker can be remotely controlled by the rotation of the first motor 703, and time is provided for maintenance work by providing a backup plan. At the same time, based on the rotation of the circular support plate 10, the second gear 702 and the first gear 701 are driven by the first motor 703 to rotate, thereby When the first gear 701 and the second gear 702 are separated, the circuit breaker switch 4 can be separated from the traction limit of the traction mechanism 7. When the circuit breaker is used normally, the second motor 705 drives the winding rod 707 to rotate, further drives the pull rope 708 to be recovered, thereby driving the second support plate 715 to move downward, and the spring 713 is stretched. At this time, the first gear 701 and the second gear 702 are separated, and the circuit breaker switch 4 can be adjusted with the remote opening and closing control of the circuit breaker body 2. When the displacement sensor 8 detects an abnormal jump, as the winding rod 707 is quickly relaxed, the second support plate 715 can be driven to move upward under the action of the spring 713 until the first gear 701 and the second gear 702 are engaged during the rotation process, and the rotation of the circular support plate 10 is limited, so that the small motor inside the circuit breaker body 2 that drives the opening and closing of the switch stops rotating, thereby completing the traction limit of the traction mechanism 7. Under this structure, the damage to the first motor 703 during daily opening and closing can be avoided, and the service life of the first motor 703 can be extended.
