Description

Technical Field

[0001] This utility model belongs to the field of disconnecting switch technology, and in particular relates to a disconnecting switch for outdoor power distribution equipment. Background Technology

[0002] Outdoor power distribution equipment refers to equipment used in power systems, especially in power distribution networks, for functions such as power distribution, protection, monitoring and control. This type of equipment is usually installed outdoors and exposed to the external environment. In order to ensure the safe operation and maintenance of power equipment, outdoor power distribution equipment is equipped with disconnecting switches.

[0003] Currently, existing outdoor power distribution equipment disconnect switches are usually relatively independent in terms of opening and grounding, and closing and disconnecting grounding operations. Although they can complete the circuit switching and grounding functions separately, they cannot achieve synchronous linkage between the two. This may result in the equipment still being energized after the circuit is disconnected when the switch is opened, which may create a safety hazard. When the switch is closed, it is also easy to cause a grounding short circuit fault due to the grounding not being disconnected in time, which seriously threatens the stable operation of the power system. Utility Model Content

[0004] The purpose of this utility model is to provide a disconnecting switch for outdoor power distribution equipment, which realizes synchronous linkage between opening and grounding, and between closing and grounding disconnection. Opening prevents the equipment from being energized, and closing prevents grounding short circuits, thereby improving the safety and reliability of the disconnecting switch, ensuring the stable operation of the power system, and solving the existing technical problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A disconnecting switch for outdoor power distribution equipment includes: a support base, on the top of which two rotating seats are symmetrically rotatably arranged, and an insulator is fixedly arranged on the top of each of the two rotating seats; The rotating base is provided with a connecting mechanism for connecting two insulators. The support base is provided with a transmission component that can ground the circuit breaker while opening and disconnect the grounding while closing the circuit breaker.

[0006] Optionally, the connecting mechanism includes two threaded sleeves that are rotatably mounted on the top of two rotating seats at different positions. The interior of each of the two threaded sleeves is threaded with a screw. The two screws are fixedly mounted with the same connecting rod at their close ends. A rectangular adjusting block is fixedly mounted on the middle section of the connecting rod.

[0007] Optionally, the transmission assembly includes a fixed base fixedly disposed on one side of the support base, a support column rotatably disposed through the top of the fixed base, a bracket II fixedly disposed at the top of the support column, a tie rod II rotatably disposed on one side of the top of the bracket II, the other end of the tie rod II rotatably connected to the lower part of one of the rotating seats, a bracket I fixedly disposed on one side of the support column below the bracket II, a tie rod I rotatably disposed at the bottom of the bracket I, a universal joint fixedly disposed at the other end of the tie rod I, a connecting frame fixedly disposed at the other end of the universal joint, and an L-shaped frame hinged to the inner side of the connecting frame.

[0008] Optionally, a rotating rod is rotatably provided on one side of the support base, a support frame is fixedly provided on the outside of one end of the rotating rod, a grounding contact rod is fixedly provided on the inside of the support frame, and the other end of the rotating rod is fixedly connected to the L-shaped frame.

[0009] Optionally, a stationary contact and a moving contact are fixedly provided on the top of the two insulators, respectively. A grounding contact frame is fixedly provided on one side of the stationary contact. The grounding contact frame is positioned corresponding to the grounding contact rod and can be disengaged. A contact with a contact clamp and an insertion contact are respectively provided at the ends of the stationary contact and the moving contact. The insertion contact can be disengaged from and inserted into the contact clamp and held by it. A terminal block is fixedly provided on the top of both the stationary contact and the moving contact.

[0010] Optionally, a connecting seat is fixedly provided at the bottom end of the support column, and a rectangular insertion hole is provided at the bottom of the connecting seat.

[0011] The embodiments of this utility model have the following beneficial effects: This invention, through the setting of the connecting mechanism, allows for flexible adjustment of the overall length by adjusting the connection position of the threaded sleeve, facilitating the adaptation of two rotating seats with different spacings. It also allows for fine-tuning of changes in the relative position of the insulators due to environmental factors or aging, ensuring the performance of the disconnecting switch. Furthermore, during opening and closing operations, it ensures that the two rotating seats and insulators rotate synchronously, enabling the moving contact to smoothly disengage from the stationary contact or accurately insert and be clamped. This greatly improves the accuracy and reliability of opening and closing operations, reduces faults and errors, and ensures the stable and reliable operation of the disconnecting switch.

[0012] This invention achieves synchronous linkage between opening and grounding, and between closing and disconnecting grounding through the transmission component. When opening, the rotating rod is driven to rotate synchronously, allowing the grounding contact rod to reliably contact the grounding contact frame to complete the grounding, thus avoiding safety hazards caused by the equipment being energized after the circuit is disconnected. When closing, while the moving contact accurately inserts into the stationary contact to restore circuit continuity, the grounding contact rod is quickly disengaged from the grounding contact frame to prevent grounding short circuit faults during normal power supply. This synchronous operation mode greatly improves the safety and reliability of the disconnecting switch operation and ensures the stable operation of the power system.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0020] Example 1 Please see Figure 1-4 As shown in the figure, this embodiment provides a disconnecting switch for outdoor power distribution equipment, including: a support base 1, a connecting mechanism and a transmission component, etc. The support base 1 serves as the basic support structure for the entire disconnecting switch. Two rotating seats 2 are symmetrically arranged on its top. The two rotating seats 2 can rotate flexibly on the support base 1. An insulator 3 is fixedly installed on the top of each of the two rotating seats 2. The insulator 3 plays the role of insulation and isolation, ensuring the safe operation of the equipment.

[0021] Two insulators 3 are respectively fixedly equipped with stationary contacts 4 and moving contacts 5 on their tops. A grounding contact frame 7 is fixedly equipped on one side of the stationary contact 4. The grounding contact frame 7 is positioned corresponding to the grounding contact rod 10 and can be disengaged. When grounding is required, the grounding contact rod 10 can reliably contact the grounding contact frame 7 to achieve the grounding function. During normal power supply, the two can quickly disengage to prevent grounding short circuit faults. The ends of the stationary contact 4 and the moving contact 5 that are close to each other are respectively equipped with a contact with a contact clamp 401 and an insertion contact 501. The insertion contact 501 can be disengaged and inserted into the contact with the contact clamp 401 and clamped by it, thereby realizing the conduction and disconnection of the circuit. A terminal block 6 is fixedly equipped on the top of both the stationary contact 4 and the moving contact 5 for connecting external circuit wires.

[0022] The rotating base 2 is equipped with a connecting mechanism for connecting two insulators 3. The connecting mechanism includes two threaded sleeves 12 that are rotatably mounted on the top of the two rotating bases 2 at different positions. The two threaded sleeves 12 can rotate freely on the rotating base 2. The interior of each threaded sleeve 12 is threaded with a screw 13. The same connecting rod 14 is fixedly mounted at the close end of the two screws 13. By rotating the rectangular adjusting block 15 fixedly mounted in the middle section outside the connecting rod 14, the screw 13 can be driven to rotate inside the threaded sleeve 12, thereby adjusting the distance between the two threaded sleeves 12. This facilitates installation and allows for fine-tuning of the relative position of the two insulators 3 during equipment operation, enhancing connection stability.

[0023] A transmission assembly is provided on the support base 1. This transmission assembly can ground the circuit breaker while opening and disconnect the grounding while closing the circuit breaker. The transmission assembly includes a fixed base 16 fixedly mounted on one side of the support base 1. The fixed base 16 provides stable support for the support column 1601. The support column 1601 is rotatably mounted through the top of the fixed base 16 and can rotate flexibly within the fixed base 16. A bracket II 21 is fixedly mounted on the top of the support column 1601. A pull rod II 22 is rotatably mounted on one side of the top of the bracket II 21. The other end of the pull rod II 22 is connected to the bracket II 21. A rotating base 2 is rotatably connected below. When the support column 1601 rotates, it drives the bracket II 21 to rotate, which in turn pulls the rotating base 2 to rotate through the tie rod II 22. A bracket I 17 is fixedly installed on one side of the support column 1601 below the bracket II 21. A tie rod I 18 is rotatably installed at the bottom of the bracket I 17. A universal joint 19 is fixedly installed at the other end of the tie rod I 18. The universal joint 19 can flexibly transmit power and change the direction of power. A connecting frame 20 is fixedly installed at the other end of the universal joint 19. An L-shaped frame 11 is hinged to the inner side of the connecting frame 20.

[0024] A rotating rod 8 is rotatably mounted on one side of the support base 1. A support frame 9 is fixedly mounted on the outside of one end of the rotating rod 8, and a grounding contact rod 10 is fixedly mounted on the inside of the support frame 9. The other end of the rotating rod 8 is fixedly connected to the L-shaped frame 11. During the transmission process, when the support column 1601 rotates, the L-shaped frame 11 is driven to move through the bracket I 17, the pull rod I 18, the universal joint 19, and the connecting frame 20, which in turn drives the rotating rod 8 to rotate, so that the grounding contact rod 10 contacts or disengages from the grounding contact frame 7, thereby realizing the grounding and grounding disconnection functions.

[0025] Example 2 Improvements based on Example 1: See Appendix Figure 4 A connecting seat 16011 is fixedly provided at the bottom of the support column 1601. A rectangular insertion hole is provided at the bottom of the connecting seat 16011. The connecting seat 16011 can be connected to the driving component through the rectangular insertion hole. The driving component provides power to make the support column 1601 rotate, thereby driving the entire transmission assembly to move and realize the opening and closing operation of the disconnecting switch as well as the grounding and disconnecting grounding functions.

[0026] The usage process and working principle of this utility model technical solution are as follows: First, the connecting rods 14, each with a screw 13 at both ends, are threadedly connected to the two threaded sleeves 12 via the screw 13. Then, the threaded sleeve 12 at one end of the installed assembly is rotated and installed on one of the rotating seats 2 via a swivel ring. Similarly, the threaded sleeve 12 at the other end of the installed assembly is rotated and installed on the other rotating seat 2 via a swivel ring. This effectively enhances the connection stability between the two insulators 3, preventing relative displacement or loosening between the insulators 3 due to external factors (such as wind, vibration, etc.) during equipment operation, thus ensuring the overall structural stability and reliability of the disconnecting switch. When the installed assembly is too long or too short, the rectangular... The rectangular adjusting block 15 rotates while driving the connecting rod 14 and its screw 13 to rotate in opposite or closer directions within the two threaded sleeves 12, thereby adjusting the distance between the two threaded sleeves 12 for easy installation on the two rotating seats 2. In actual use, due to environmental factors, equipment aging, etc., the relative position between the two insulators 3 may change slightly, affecting the performance of the disconnecting switch. By operating the rectangular adjusting block 15, the connection position of the connecting rod 14 and the screw 13 can be finely adjusted, thereby adjusting the relative position between the two insulators 3 and restoring the disconnecting switch to its optimal working state. When a tripping operation is required, the drive component connects to the connecting seat 16011 at the bottom of the support column 1601 through the rectangular insertion hole at the bottom of the connecting seat 16011. This allows the support column 1601 to rotate on the fixed seat 16. When the support column 1601 rotates, the bracket II 21 at its top rotates accordingly. The pull rod II 22, which is rotatably mounted on one side of the top of the bracket II 21, pulls one of the rotating seats 2, causing the rotating seat 2 to rotate on the top of the support seat 1. At the same time, the bracket I 17 located below the bracket II 21 on one side of the support column 1601 also rotates with the support column 1601. 1. When the bracket I17 rotates, the pull rod I18, which is rotatably mounted at the bottom, is driven. The universal joint 19 and the connecting frame 20 at the other end of the pull rod I18 transmit power, causing the L-shaped frame 11, which is hinged to the inner side of the connecting frame 20, to move. The L-shaped frame 11 drives the rotating rod 8, which is fixedly connected to it, to rotate on one side of the support base 1. The support frame 9, which is fixedly mounted on the outside of one end of the rotating rod 8, and the grounding contact rod 10, which is fixedly mounted on the inner side of the support frame 9, rotate accordingly, so that the grounding contact rod 10 rotates to correspond to and contact the grounding contact frame 7, which is fixedly mounted on one side of the stationary contact 4, thereby realizing the grounding function. As one of the rotating blocks 2 rotates, the other rotating block 2 connected by the connecting mechanism also rotates synchronously, causing the two insulators 3 fixed on the top of the two rotating blocks 2 to rotate as well. This, in turn, drives the stationary contact 4 and the moving contact 5 fixed on the top of the two insulators 3 to move (the connecting mechanism connects the two rotating blocks 2, which enables the two rotating blocks 2 and the insulators 3 to move in unison, ensuring that the two rotating blocks 2 rotate synchronously, so that the moving contact 5 can smoothly disengage from the stationary contact 4, improving the accuracy and reliability of the opening operation). The insert contact 501 set at one end of the moving contact 5 disengages from the contact clamp contact 401 set at one end of the stationary contact 4, completing the opening operation. At this time, the circuit is disconnected and grounded. When a closing operation is required, the drive component reverses its movement, causing the support column 1601 to rotate in the opposite direction. Following the reverse movement process of each component during the opening operation, the rotating seat 2 rotates in the opposite direction, causing the insulator 3, stationary contact 4, and moving contact 5 to move. (The connecting mechanism ensures that the two rotating seats 2 and insulator 3 are accurately reset, allowing the moving contact 5 to be accurately inserted into the stationary contact 4 and clamped, thereby improving the accuracy and reliability of the closing operation and reducing faults and errors during operation.) The insert contact 501 on the moving contact 5 is re-inserted into the contact clamp contact 401 on the stationary contact 4 and clamped by it, realizing the circuit conduction. At the same time, the rotating rod 8 rotates in the opposite direction, causing the support frame 9 and the grounding contact rod 10 to rotate, causing the grounding contact rod 10 to disengage from the grounding contact frame 7 and disconnecting the grounding.
