Description

Technical Field

[0001] This utility model relates to the field of disconnecting switchgear technology, and more specifically, to a modular disconnecting switch structure. Background Technology

[0002] In power systems, disconnect switches are crucial devices used for isolation, switching, and grounding operations in circuits to ensure the safe operation of the power system and the maintenance of equipment. Traditional disconnect switch structures often employ an integrated design, where all components are fixedly connected together to form a single unit. While this design meets usage requirements to some extent, it has several shortcomings.

[0003] First, the traditional integrated disconnect switch structure is very inconvenient to maintain and replace. Because the components are tightly connected, if a component fails or needs to be upgraded, the entire disconnect switch often needs to be disassembled. This not only increases maintenance costs but also prolongs downtime, adversely affecting the stable operation of the power system.

[0004] Secondly, traditional disconnect switches have poor scalability and flexibility. With the development of power systems, the performance and capacity requirements for disconnect switches are constantly increasing. However, the integrated design makes the expansion and upgrading of disconnect switches very difficult, often requiring the redesign and remanufacturing of the entire device, which undoubtedly increases cost and complexity.

[0005] Furthermore, traditional disconnect switches have a complex structure and a cumbersome manufacturing and assembly process, resulting in low production efficiency and difficulty in ensuring product consistency and reliability. Over long-term use, the performance and stability of the disconnect switch will gradually decline due to wear and aging of the components.

[0006] Therefore, to solve the above problems, there is an urgent need for a new type of disconnecting switch structure, which should be modular, easy to maintain, highly expandable, simple in structure, and convenient to manufacture and assemble. This modular disconnecting switch structure can not only improve the reliability and stability of the equipment, but also reduce maintenance and upgrade costs, providing a strong guarantee for the safe operation of the power system. Utility Model Content

While this design meets some usage requirements, it has numerous drawbacks.

[0008] To achieve the above objectives, this utility model provides a modular disconnect switch structure, including a plurality of contact modules, which are stacked sequentially to form a contact group. An operating mechanism module is connected to one end of the contact group via a connecting module. A contact module transmission component is installed in the middle of adjacent contact modules, and a connecting module transmission component is installed in the middle of the connecting module.

[0010] Preferably, the connection module includes a first circular hole connected to one end of the module fixing member, a second circular hole connected to and positioned by the operating mechanism module, a third circular hole for positioning and connecting the module transmission member, a circular recessed step for positioning the contact module, and a fourth circular hole for cooperating with the operating mechanism module.

[0011] Preferably, the operating mechanism module includes an upper housing and a lower housing. An input drive shaft is installed on one side of the middle portion of the upper housing and the lower housing, and an output drive shaft is installed on the other side. The upper housing is provided with a number of mechanism positioning holes and a number of mechanism connection holes. The lower housing is provided with a remote control interface hole, a number of contact module positioning countersunk holes, and a number of operating mechanism fixing holes.

[0012] Preferably, the module fixing component includes a support rod, and the end of the support rod is provided with a threaded end.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. In this modular disconnector structure, the modular design makes each component relatively independent.

[0020] 2. This modular disconnector structure allows for flexible increases or decreases in the number of contact modules based on actual needs, easily expanding the performance and capacity of the disconnector. This design enables the disconnector to better adapt to the evolving needs of the power system, reducing the difficulty and cost of equipment upgrades and modifications.

[0021] 3. In this modular disconnector structure, the modular disconnector has a relatively simple structure. Each module can be manufactured and assembled independently before being combined. This manufacturing method not only improves production efficiency but also ensures product consistency and reliability, reducing the risk of performance degradation due to component wear and aging.

[0022] 4. In this modular disconnector structure, the modular design ensures a tighter and more stable connection between the various components, reducing the occurrence of faults caused by loose or worn parts. Furthermore, by optimizing the structure and performance of each module, the reliability and stability of the entire disconnector can be further improved, providing strong support for the safe operation of the power system.

[0036] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] This utility model provides a modular disconnector switch structure, such as... Figures 1-11As shown, the circuit includes several contact modules 1, which are stacked sequentially to form a contact group. One end of the contact group is connected to an operating mechanism module 7 via a connecting module 5. A contact module transmission component 2 is installed in the middle of adjacent contact modules 1, and a connecting module transmission component 4 is installed in the middle of the connecting module 5. Module fixing components 6 pass through the contact modules 1. The stacking design of the contact modules 1 allows the disconnecting switch structure to easily increase or decrease the number of contacts according to actual needs, achieving a high degree of modularity and scalability. This design not only facilitates production and maintenance but also allows for flexible capacity adjustment as the power system develops. The connection between one end of the contact group and the operating mechanism module 7 via the connecting module 5 ensures that operating commands are accurately and stably transmitted to the contact modules, enabling reliable switching operation of the disconnecting switch. Simultaneously, the robust connection between the connecting module 5 and the contact modules 1 enhances the stability of the entire disconnecting switch structure. A contact module transmission component 2 is installed in the middle of adjacent contact module 1, and a connection module transmission component 4 is also provided in the middle of connection module 5. The design of these transmission components enables the operating force of operating mechanism module 7 to be smoothly transmitted to each contact module, realizing efficient transmission and synchronous operation.

[0038] A module fixing piece 6 is inserted between the contact modules 1. This design not only simplifies the assembly process of the disconnecting switch, but also makes it more convenient to maintain or replace the contact modules without disassembling the entire disconnecting switch structure, which greatly reduces maintenance costs and downtime.

[0039] In this embodiment, the contact module 1 includes a base 101, a cover 102 mounted on the back of the base 101, and a first lead-out terminal 103 and a second lead-out terminal 104 mounted on both sides of the base 101, respectively. The base 101 has a module connector hole 1011 and a first central circular positioning hole 1012 for rotating and positioning the contact system. The cover 102 includes a module connection positioning hole 1021 and a second central circular positioning hole 1022 for rotating and positioning the contact system. The combination design of the base 101 and cover 102 in the contact module 1 not only protects the internal contact system but also achieves a stable connection with the external circuit through the first lead-out terminal 103 and the second lead-out terminal 104. The module connector hole 1011 and the first central circular positioning hole 1012 on the base, as well as the module connection positioning hole 1021 and the second central circular positioning hole 1022 on the cover, together ensure the precise positioning and stable connection of the contact module during stacking and installation, improving the overall stability and reliability of the disconnector switch.

[0040] Specifically, the connecting module 5 includes a first circular hole 1051 connected to one end of the module fixing member 6, a second circular hole 1052 connected to and positioned by the operating mechanism module 7, a third circular hole 1053 positioned by the connecting module transmission member 4, a circular recessed step 1054 positioned by the contact module 1, and a fourth circular hole 1055 cooperating with the operating mechanism module 7. This series of designs makes the connecting module a key connection point in the disconnecting switch structure, ensuring the accurate transmission of operating commands and the close cooperation between the various modules.

[0041] Furthermore, the operating mechanism module 7 includes an upper housing 702 and a lower housing 703. An input drive shaft 701 is installed on one side of the middle portion of the upper housing 702 and the lower housing 703, and an output drive shaft 704 is installed on the other side. The upper housing 702 is provided with several mechanism positioning holes 7021 and several mechanism connection holes 7022. The lower housing 703 has a remote control interface hole 7031, several contact module positioning countersunk holes 7032, and several operating mechanism fixing holes 7033. The operating mechanism module 7 is composed of the upper housing 702 and the lower housing 703, and the input drive shaft 701 and the output drive shaft 704 are installed inside, realizing the input and output of operating commands. The mechanism positioning hole 7021 and mechanism connection hole 7022 on the upper housing, as well as the remote control interface hole 7031, contact module positioning countersunk hole 7032 and operating mechanism fixing hole 7033 on the lower housing, provide convenience for the installation, positioning and external control of the operating mechanism, and enhance the flexibility and controllability of the disconnecting switch.

[0042] Furthermore, the module fixing component 6 includes a support rod 601, the end of which is provided with a threaded end 602. The module fixing component 6 adopts the design of support rod 601 and threaded end 602, through which the support rod passes through each contact module in sequence and is threadedly connected to the first circular hole 1051 of the connecting module 5, thereby realizing the stable fixing and easy disassembly of the contact module, which facilitates the assembly and maintenance of the disconnecting switch.

[0043] Furthermore, the connecting module transmission component 4 includes a transmission sleeve 401, which has a first transmission connection hole 4011, a second transmission connection hole 4012, and an intermediate positioning rotation hole 4013. The transmission sleeve 401 and the transmission plate 3 are connected in series to transmit the operation commands of the operating mechanism module 7 to the contact module 1. Through the combined design of the transmission sleeve 401 and the transmission plate 3, the connecting module transmission component 4 realizes the transmission of the operation commands of the operating mechanism module 7 to the contact module 1. The first transmission connection hole 4011, the second transmission connection hole 4012, and the intermediate positioning rotation hole 4013 on the transmission sleeve, as well as the insertion and engagement of the transmission plate and the connecting sleeve, ensure the stability and accuracy of the transmission process.

[0044] Furthermore, adjacent transmission sleeves 401 are connected by transmission plates 3. Connecting sleeves 4014 are installed on the bottom of both sides of the transmission sleeve 401. The top of the transmission plate 3 is inserted into the upper connecting sleeve 4014, and the bottom of the transmission plate 3 is inserted into the lower first transmission connection hole 4011 and second transmission connection hole 4012. This design, with transmission plates 3 connecting adjacent transmission sleeves 401 and connecting sleeves 4014 installed on the bottom of both sides of the transmission sleeve, ensures the transmission plates are securely connected between the transmission sleeves, guaranteeing effective transmission of power and improving the operating efficiency of the disconnecting switch.

[0045] Furthermore, the support rod 601 passes through each contact module 1 in sequence, and the first circular hole 1051 is provided with an internal thread. The threaded end 602 is threadedly connected to the first circular hole 1051 of the connecting module 5. This design not only achieves a stable fixation of the contact module, but also facilitates quick assembly and disassembly of the contact module by rotating the support rod, thus improving the maintainability of the disconnecting switch.

[0046] Furthermore, the connecting module 5 and the operating mechanism module 7 are connected and fixed together by the mechanism module fixing part 8. This design enhances the connection strength between the connecting module and the operating mechanism module, ensuring the accurate transmission of operating commands and the stable operation of the disconnecting switch.

[0047] Furthermore, a cover plate 9 is installed on the outside of the operating mechanism module 7. This not only protects the internal components of the operating mechanism module from interference from the external environment, but also improves the overall aesthetics and protection level of the disconnect switch.

[0048] In use, the modular disconnector structure of this invention first determines the required number of contact modules 1 according to actual needs, and then stacks these contact modules sequentially to form a contact group. Each contact module 1 includes a base 101 and a cover 102, which together protect the internal contact system and are connected to the external circuit through a first lead-out terminal 103 and a second lead-out terminal 104. Next, a module fixing member 6 (a support rod 601 with a threaded end 602) is sequentially passed through each contact module 1 and threadedly connected to the first circular hole 1051 of the connecting module 5, achieving a stable fixation of the contact modules. This design makes the contact modules easy to disassemble and replace, reducing maintenance costs and downtime.

[0049] Contact module transmission component 2 is installed in the middle of adjacent contact module 1, and connection module transmission component 4 is installed in the middle of connection module 5. These transmission components form an efficient transmission link through the combination design of transmission sleeve 401 and transmission plate 3. The transmission sleeve 401 has a first transmission connection hole 4011, a second transmission connection hole 4012, and an intermediate positioning rotation hole 4013, which are inserted and matched with the transmission plate 3 to ensure the stability and accuracy of the transmission process. Adjacent transmission sleeves 401 are connected by transmission plates 3, and connecting sleeves 4014 are installed at the bottom of both sides of the transmission sleeve. This design allows the transmission plates to be firmly connected between the transmission sleeves, ensuring the effective transmission of power.

[0050] The connecting module 5 is connected to and positioned with the operating mechanism module 7 through the second circular hole 1052. The operating mechanism module 7 consists of an upper housing 702 and a lower housing 703, and internally houses an input drive shaft 701 and an output drive shaft 704 for receiving external operating commands and transmitting them to the contact module. The mechanism positioning hole 7021 and mechanism connecting hole 7022 on the upper housing 702, and the contact module positioning countersunk hole 7032 and operating mechanism fixing hole 7033 on the lower housing 703, facilitate the installation and positioning of the operating mechanism. The connecting module 5 and the operating mechanism module 7 are connected and fixed together by a mechanism module fixing member 8, enhancing the connection strength and ensuring the accurate transmission of operating commands.

[0051] When an external operation command is transmitted to the operating mechanism module 7 via the input drive shaft 701, the command is converted into mechanical motion and transmitted to each contact module 1 through the connecting module transmission component 4 and the contact module transmission component 2. The contact module performs switching operations according to the received command, realizing the isolation and connection of the power system. At the same time, the remote control interface hole 7031 on the lower housing of the operating mechanism module 7 allows for remote operation and control, improving the flexibility and controllability of the disconnecting switch.

[0052] Finally, a cover plate 9 is installed on the outside of the operating mechanism module 7 to protect the internal components from interference from the external environment and to improve the overall aesthetics and protection level of the disconnecting switch.
