Description

Technical Field

[0001] The invention relates to the technical field of power switches, and in particular to an improved structure of a bypass switch. Background Art

[0002] The power switch is a key device used to control the on and off of the circuit in the power system. It plays a vital role in ensuring the safety, reliability and flexibility of power supply. There are many types of power switches, which can be divided into multiple types according to different classification standards. For example, according to the arc extinguishing medium, it can be divided into air switches, oil switches, vacuum switches, SF6 switches, etc.; according to the operation mode, it can be divided into manual switches, electric switches, pneumatic switches and hydraulic switches, etc.; according to the purpose, it can be divided into circuit breakers, disconnectors, load switches, fuses, etc. With the continuous expansion of the scale of power systems and the improvement of voltage levels, the performance requirements for bypass switches are becoming increasingly stringent. Therefore, an improved bypass switch structure is particularly needed.

[0003] However, the existing bypass switch needs to be frequently connected during the power transmission and distribution process to realize the circuit connection and disconnection functions. When the joint is closed, due to the fast movement speed and large joint mass, a large impact force will be generated. Long-term wear will change the shape and size of the joint and reduce the effective contact area between the joints. Moreover, when the circuit is not connected, the exposed joint is easily affected by external environmental factors. For example, moisture, dust, etc. entering the switch will damage electrical components and mechanical parts, affecting the performance and life of the bypass switch.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the new embodiment of the present invention to clearly and completely describe the technical solutions in the new embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention patent, not all the embodiments. Based on the embodiment in the present invention patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention patent.

[0026] See also Figure 1-8The present invention provides a technical solution: an improved bypass switch structure, including a bypass switch body 1, a handle 2 is fixedly connected to one side surface of the bypass switch body 1, a stabilizing column 3 is fixedly connected to one side surface of the bypass switch body 1, a stabilizing groove 4 is provided on the inner side surface of the stabilizing column 3, a driving spindle 5 is rotatably connected to the inner side surface of the stabilizing groove 4, a rotating plate 6 is fixedly connected to one end surface of the driving spindle 5, a fixing mechanism 7 is provided on one side surface of the bypass switch body 1, and a packaging mechanism 8 is provided on one side surface of the bypass switch body 1;

[0027] The packaging mechanism 8 includes a connecting block 801, a connecting shell 802, a fixing column 803, a moving groove 804, a moving block 805, a connecting column 806, a joint 807, a spring 808, a first ball groove 809, a ball 810, a fixing ring 811, a ball limiting groove 812, a sealing block 813 and a second ball groove 814. The connecting block 801 is bolted to one side surface of the bypass switch body 1, the connecting shell 802 is fixedly connected to one side surface of the connecting block 801, the moving groove 804 is fixedly connected to the inner side surface of the connecting shell 802, the moving block 805 is slidably connected to the inner side surface of the moving groove 804, the connecting column 806 is fixedly connected to one end surface of the moving block 805, and the connecting column 806 is fixedly connected to one end surface of the joint 80 7. A spring 808 is fixedly connected to one end surface of the joint 807, a first ball groove 809 is provided on the outer surface of the connecting shell 802, a ball 810 is rotatably connected to the inner surface of the first ball groove 809, a fixing ring 811 is threadedly connected to the outer surface of the connecting shell 802, a ball limiting groove 812 is provided on the inner surface of the fixing ring 811, a sealing block 813 is rotatably connected to the outer surface of the ball 810, a second ball groove 814 is provided on the outer surface of the sealing block 813, and a connecting block 801, a connecting shell 802, a fixing column 803, a movable groove 804, a movable block 805, a connecting column 806, a joint 807, a spring 808, a first ball groove 809, a ball 810, a fixing ring 811, and a ball limiting groove are connected to the outer surface of the ball 810. 812, the sealing block 813 and the second ball groove 814 are set. When in use, when the bypass switch is connected, the connection block 801 is bolted to the side surface of the bypass switch body 1, providing a connection basis for the entire packaging mechanism 8 with the switch body. When the joint 807 is driven by an external force, the moving block 805 can slide in a specific direction in the moving groove 804, ensuring the linearity and stability of the movement of the joint 807, thereby ensuring that the joint 807 can accurately complete the action during the opening and closing operation. During the movement of the joint 807, whether it is closing or separating, the spring 808 plays a key buffering role. When the joint 807 is closed, a large impact force will be generated, and the spring 808 absorbs and buffers the impact of the joint 807. Energy is reduced, and wear and damage caused by collision between joints 807 and between joints 807 and other parts are reduced. During the separation process of joints 807, the elastic force of spring 808 also helps to smoothly separate joints 807. A first ball groove 809 is provided on the outer surface of the connecting shell 802, in which the rotatably connected ball 810 cooperates with the second ball groove 814 on the outer side of the sealing block 813. At the same time, the fixing ring 811 threadedly connected to the outer side of the connecting shell 802, and the ball limiting groove 812 on the inner side thereof limits the position of the ball 810. Under normal working conditions, the fixing ring 811 is tightened, and the sealing block 813 tightly covers the opening of the connecting shell 802 through the limiting and support of the ball 810 in the second ball groove 814.When it is necessary to open the packaging mechanism 8 for wiring, the fixing ring 811 is rotated, and the ball 810 moves into the ball limiting groove 812, and the sealing block 813 can move smoothly along the outer surface of the connection shell 802, thereby opening the opening of the connection shell 802. After the operation is completed, the fixing ring 811 is rotated in the opposite direction to make the sealing block 813 return to the second ball groove 814 to complete the fixation. The spring 808 buffer and dustproof design in the packaging mechanism 8 improves the performance and protection effect of the joint, improves the overall reliability and service life of the bypass switch, and meets the increasingly stringent performance requirements of modern power systems for bypass switches.

[0028] Furthermore, the handle 2 is provided with two groups, and the inner size of the stabilizing groove 4 is consistent with the outer size of the driving spindle 5. Through the setting of the stabilizing groove 4 and the driving spindle 5, when in use, during the operation of the bypass switch, vibration will be generated. The precise matching of the stabilizing groove 4 and the driving spindle 5 can prevent the shaking of the driving spindle 5 caused by vibration, thereby ensuring that the switch can accurately complete the opening and closing actions each time it is operated, and maintain stable electrical performance.

[0029] Furthermore, the inner dimension of the movable groove 804 is consistent with the outer dimension of the movable block 805, and multiple groups of ball bearings 810 are arranged. Through the arrangement of the movable groove 804, the movable block 805 and the ball bearings 810, when in use, the inner dimension of the movable groove 804 is consistent with the outer dimension of the movable block 805, which provides precise guidance for the sliding of the movable block 805 in the movable groove 804, so that the movable block 805 can only move in a straight line along the direction of the movable groove 804. Since the two are tightly fitted, there will be no obvious shaking or loosening during the movement. Multiple groups of ball bearings 810 are arranged, which reduces the friction between the sealing block 813 and the connecting shell 802. When rotating the fixing ring 811 to move the sealing block 813, the operator can operate more easily.

[0030] Furthermore, the outer surface of the connecting shell 802 is provided with a thread, and the inner surface of the fixing ring 811 is provided with a thread. Through the setting of the connecting shell 802 and the fixing ring 811, when in use, the threads set on the outer surface of the connecting shell 802 and the inner surface of the fixing ring 811 constitute a spiral sub-structure. When the fixing ring 811 is connected to the connecting shell 802 by threaded rotation, the rotational motion is converted into axial displacement and pressure. As the fixing ring 811 rotates, it will gradually approach the sealing block 813 along the axial direction of the connecting shell 802. The threaded connection method can generate a larger axial tightening force. When the fixing ring 811 is tightened, it will apply a uniform axial pressure to the sealing block 813, thereby achieving a good sealing effect.

[0031] Furthermore, the fixing mechanism 7 includes a fixing block 701, a motor 702, a positive and negative screw rod 703, a connecting plate 704, a fixing plate 705, a sliding block 706, a limiting block 707, a limiting plate 708, a sliding groove 709 and a limiting groove 710. The fixing block 701 is fixedly connected to one side surface of the bypass switch body 1, the motor 702 is fixedly connected to one side surface of the fixing block 701, the positive and negative screw rod 703 is fixedly connected to one end surface of the motor 702, the outer surface of the positive and negative screw rod 703 is threadedly connected to the connecting plate 704, and the fixed plate 704 is fixedly connected to one side surface of the connecting plate 704. The fixed plate 705 and the upper surface of the connecting plate 704 are fixedly connected with a sliding block 706, one side surface of the sliding block 706 is fixedly connected with a limiting block 707, the outer surface of the limiting block 707 is slidably connected with a limiting plate 708, the inner surface of the limiting plate 708 is provided with a sliding groove 709, and the inner surface of the sliding groove 709 is provided with a limiting groove 710. Through the arrangement of the fixed block 701, the motor 702, the forward and reverse screw rods 703, the connecting plate 704, the fixed plate 705, the sliding block 706, the limiting block 707, the limiting plate 708, the sliding groove 709 and the limiting groove 710, When in use, the motor 702 is fixedly connected to one side surface of the fixed block 701. When the motor 702 receives a start signal, it starts to run. The output shaft of the motor 702 is fixedly connected to one end of the forward and reverse screw rods 703, thereby driving the forward and reverse screw rods 703 to start rotating. When the forward and reverse screw rods 703 rotate, due to the interaction between the threads, the connecting plate 704 will move linearly along the axial direction of the screw rod. Since the threads on the forward and reverse screw rods 703 are relatively arranged, when the screw rod rotates clockwise, a part of the connecting plate 704 will move in one direction along the screw rod, while the other part of the connecting plate 704 will move in one direction. It will move in the opposite direction. During the axial movement of the connecting plate 704 along the forward and reverse screw rods 703, the sliding block 706 will slide in the sliding groove 709 of the limiting plate 708. The sliding cooperation provides a stable guiding path for the movement of the connecting plate 704. At the same time, the limiting block 707 will slide in the limiting groove 710 to further accurately limit the movement of the connecting plate 704. When the connecting plate 704 moves to the appropriate position under the drive of the forward and reverse screw rods 703, the fixing plate 705 can be used to cooperate with external equipment to fix the bypass switch body 1.

[0032] Furthermore, the connecting plate 704 is provided with multiple groups, and the connecting plate 704 forms a sliding structure through the forward and reverse screw rods 703 and the motor 702. The threads on the surfaces of the forward and reverse screw rods 703 are arranged relatively. Through the arrangement of the connecting plate 704, the forward and reverse screw rods 703 and the motor 702, when in use, the multiple groups of connecting plates 704 can fix and support the bypass switch body 1 at different positions, making the fixation more stable. When the motor 702 starts and drives the forward and reverse screw rods 703 to rotate, based on the principle of thread transmission, the rotational movement of the forward and reverse screw rods 703 will be converted into a linear movement of the connecting plate 704 along the axial direction of the screw rod. The structure in which the motor 702 drives the forward and reverse screw rods 703 to rotate and drive the connecting plate 704 to slide constitutes a sliding structure that can accurately control the position of the connecting plate 704, making the fixation more stable and accurate. The threads on the surfaces of the forward and reverse screw rods 703 are arranged relatively, so that when the screw rod rotates, driving effects in different directions can be achieved, providing a basis for different movement modes of the subsequent connecting plate 704.

[0033] Furthermore, the limit plate 708 is fixedly connected to the fixed block 701, and the outer dimension of the sliding block 706 is consistent with the inner dimension of the sliding groove 709. Through the arrangement of the limit plate 708, the fixed block 701, the sliding block 706 and the sliding groove 709, when in use, the fixed block 701 serves as an installation support part for components such as the motor 702 and the forward and reverse screw rods 703, and has high stability. The fixed connection between the limit plate 708 and the fixed block 701 further enhances the integrity and rigidity of this supporting structure, making the entire fixing mechanism 7 more stable. The size-matching design enables the sliding block 706 to maintain a stable motion state in the sliding groove 709, and the sliding block 706 fits tightly with the sliding groove 709, so that the connecting plate 704 can remain stable during movement.

[0034] Furthermore, two groups of limit blocks 707 are symmetrically arranged around the central axis of the sliding block 706, and the outer size of the limit block 707 is consistent with the inner size of the limit groove 710. Through the setting of the limit block 707, the sliding block 706 and the limit groove 710, when in use, when the connecting plate 704 moves under the drive of the forward and reverse screw rods 703, the two groups of limit blocks 707 will interact with the limit groove 710 at the same time. The two symmetrically arranged groups of limit blocks 707 can evenly limit the displacement of the sliding block 706 and the connecting plate 704 in the direction perpendicular to the sliding groove 709 from both sides, so that the entire structure can maintain a more balanced state when responding to external forces, and effectively prevent the displacement or deformation of components caused by excessive force on one side. The outer size of the limit block 707 is consistent with the inner size of the limit groove 710, so that the limit block 707 slides more smoothly and stably in the limit groove 710.

[0035] Working principle: During the operation of the bypass switch, a torque is applied by rotating the plate 6 to rotate the drive spindle 5. The inner size of the stabilizing groove 4 matches the outer size of the drive spindle 5 to ensure the stability of the drive spindle 5 during rotation, so that it will not have radial shaking or deviation, thereby ensuring that the switch can accurately complete the opening and closing actions each time it is operated, and maintaining stable electrical performance. When the bypass switch body 1 needs to be fixed, the motor 702 is fixedly connected to one side surface of the fixing block 701. When the motor 702 receives the start signal and starts to run, the output shaft of the motor 702 is fixedly connected to one end of the forward and reverse screw rod 703, thereby driving the forward and reverse screw rod 703 to start rotating. When the forward and reverse screw rod 703 rotates, since the threads on the forward and reverse screw rod 703 are arranged relatively, when When the screw rod rotates clockwise, a part of the connecting plate 704 will move in one direction along the screw rod, while the other part of the connecting plate 704 will move in the opposite direction. The rotational movement of the forward and reverse screw rods 703 will be converted into a linear movement of the connecting plate 704 along the axial direction of the screw rod. The structure in which the forward and reverse screw rods 703 are driven by the motor 702 to rotate and drive the connecting plate 704 to slide constitutes a sliding structure that can accurately control the position of the connecting plate 704, making the fixation more stable and accurate. The threads on the surfaces of the forward and reverse screw rods 703 are arranged relatively to each other, so that when the screw rod rotates, driving effects in different directions can be achieved, which provides a basis for the subsequent different movement modes of the connecting plate 704. In the process of the connecting plate 704 moving along the axial direction of the forward and reverse screw rods 703, the sliding block 706 will The connection plate 704 slides in the sliding groove 709 of the limit plate 708, and the sliding cooperation provides a stable guiding path for the movement of the connection plate 704. At the same time, the limit block 707 will slide in the limit groove 710 to further accurately limit the movement of the connection plate 704. When the connection plate 704 moves to a suitable position under the drive of the positive and negative screw rods 703, the fixing plate 705 can be used to cooperate with external equipment to achieve the fixing effect on the bypass switch body 1. When the bypass switch is connected, the connection block 801 is bolted to the side surface of the bypass switch body 1, providing a connection basis for the entire packaging mechanism 8 with the switch body. When the connector 807 is driven by an external force, the moving block 805 can slide in a specific direction in the moving groove 804 to ensure the connector. The linearity and stability of the movement of 807 ensure that the joint 807 can accurately complete the action during the opening and closing operation. During the movement of the joint 807, whether it is closing or separating, the spring 808 plays a key buffering role. When the joint 807 is closed, a large impact force will be generated. The spring 808 absorbs and buffers the impact energy of the joint 807, reducing the wear and damage caused by collision between the joints 807 and between the joint 807 and other components. During the separation process of the joint 807, the elastic force of the spring 808 also helps to separate the joint 807 smoothly. A first ball groove 809 is provided on the outer surface of the connecting shell 802, wherein the rotatably connected ball 810 cooperates with the second ball groove 814 on the outer side of the sealing block 813.At the same time, the fixing ring 811 threadedly connected to the outer side of the connecting shell 802 and the ball limiting groove 812 on the inner side thereof limit the position of the ball 810. Under normal working conditions, the fixing ring 811 is tightened, and the ball 810 is limited and supported in the second ball groove 814, so that the sealing block 813 tightly covers the opening of the connecting shell 802. When it is necessary to open the packaging mechanism 8 for wiring, the fixing ring 811 is rotated, and the ball 810 moves into the ball limiting groove 812, and the sealing block 813 can be moved along the connecting shell The outer surface of 802 moves smoothly, thereby opening the opening of the connecting shell 802. After the operation is completed, the fixing ring 811 is rotated in the opposite direction to make the sealing block 813 return to the second ball groove 814 to complete the fixation. The spring 808 in the packaging mechanism 8 is designed to buffer and prevent dust, which improves the performance and protection effect of the joint, improves the overall reliability and service life of the bypass switch, and meets the increasingly stringent performance requirements of the modern power system for the bypass switch. The model of the motor 702 is YE2-132S-4.
