Description

Technical Field

[0001] The invention relates to the technical field of isolating switch equipment, and in particular to a modular isolating switch structure. Background Art

[0002] In the power system, the isolating switch is an important device used to perform isolation, switching and grounding operations in the circuit to ensure the safe operation of the power system and the maintenance of the equipment. The traditional isolating switch structure often adopts an integrated design, that is, all components are fixedly connected together to form a whole. Although this design meets the use requirements to a certain extent, it has many shortcomings.

[0003] First, the traditional integrated disconnector structure is very inconvenient to maintain and replace. Since the components are closely connected, once a component needs production testing and repair, the entire disconnector needs to be disassembled, which not only increases maintenance costs, but also prolongs downtime, adversely affecting the stable operation of the power system.

[0004] Secondly, the scalability and flexibility of traditional disconnectors are poor. With the development of power systems, the performance and capacity requirements for disconnectors are also increasing. However, the integrated design makes it very difficult to expand and upgrade disconnectors, often requiring the redesign and manufacture of the entire device, which undoubtedly increases costs and complexity.

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

[0006] Therefore, in order to solve the above problems, a new type of disconnector structure is urgently needed, which should have the characteristics of modularization, easy maintenance, strong scalability, simple structure, and convenient manufacturing and assembly. This modular disconnector structure can not only improve the reliability and stability of the equipment, but also reduce the maintenance and upgrade costs, providing a strong guarantee for the safe operation of the power system. Summary of the invention

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The present invention provides a modular isolating switch structure, such as Figure 1-Figure 11As shown, it includes a plurality of contact modules 1, which are stacked in sequence to form a contact group. The outer side of one end of the contact group is connected to an operating mechanism module 7 through a connecting module 5, a contact module transmission member 2 is installed in the middle of adjacent contact modules 1, a connecting module transmission member 4 is installed in the middle of the connecting module 5, and a module fixing member 6 is inserted between the contact modules 1. The stacking design of the contact modules 1 allows the disconnector structure to easily increase or decrease the number of contacts according to actual needs, achieving a high degree of modularity and scalability. This design is not only convenient for production and maintenance, but also can flexibly adjust the capacity as the development needs of the power system. The outer side of one end of the contact group is connected to the operating mechanism module 7 through the connecting module 5, ensuring that the operating instructions can be accurately and stably transmitted to the contact module, thereby realizing reliable switching operation of the disconnector. At the same time, the stable connection between the connecting module 5 and the contact module 1 also enhances the stability of the entire disconnector structure. A contact module transmission member 2 is installed in the middle of adjacent contact modules 1, and a connection module transmission member 4 is also installed in the middle of the connection module 5. The design of these transmission members enables the operating force of the operating mechanism module 7 to be smoothly transmitted to each contact module, achieving efficient transmission and synchronous operation.

[0038] Module fixings 6 are provided between the contact modules 1. This design not only simplifies the assembly process of the isolating switch, but also makes it more convenient to maintain or replace the contact modules without disassembling the entire isolating switch structure, thereby greatly reducing maintenance costs and downtime.

[0039] In this embodiment, the contact module 1 includes a base 101, a cover 102 is installed on the back of the base 101, and a first lead terminal 103 and a second lead terminal 104 are installed on both sides of the base 101; the base 101 is provided with a module connector hole 1011 and a first central circular positioning hole 1012 for rotation and positioning of the contact system; the cover 102 includes a module connection positioning hole 1021 and a second central circular positioning hole 1022 for rotation and positioning of the contact system. The contact module 1 adopts a combined design of the base 101 and the cover 102, which not only protects the internal contact system, but also realizes a stable connection with the external circuit through the first lead terminal 103 and the second lead terminal 104. The module connector hole 1011 and the first central circular positioning hole 1012 on the base, and 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, and improve the overall stability and reliability of the disconnector.

[0040] Specifically, the connection module 5 includes a first circular hole 1051 connected to one end of the module fixing member 6, a second circular hole 1052 connected and positioned with the operating mechanism module 7, a third circular hole 1053 for positioning the connection module transmission member 4, a circular concave step 1054 positioned with the contact module 1, and a fourth circular hole 1055 matched with the operating mechanism module 7. This series of designs makes the connection module a key connection point in the disconnector structure, ensuring the accurate transmission of operating instructions and the close matching between various modules.

[0041] Furthermore, the operating mechanism module 7 includes an upper shell 702 and a lower shell 703, an input transmission shaft 701 is installed on one side of the middle of the upper shell 702 and the lower shell 703, and an output transmission shaft 704 is installed on the other side; a plurality of mechanism positioning holes 7021 and a plurality of mechanism connection holes 7022 are provided on the upper shell 702; a remote control interface hole 7031 is opened on the lower shell 703, and a plurality of contact module positioning countersunk holes 7032 and a plurality of operating mechanism fixing holes 7033 are provided on the lower shell 703. The operating mechanism module 7 consists of an upper shell 702 and a lower shell 703, and an input transmission shaft 701 and an output transmission shaft 704 are installed inside, so as to realize the input and output of the operating instructions. The mechanism positioning hole 7021 and the mechanism connecting hole 7022 on the upper shell, as well as the remote control interface hole 7031, the contact module positioning countersunk hole 7032 and the operating mechanism fixing hole 7033 on the lower shell, facilitate the installation, positioning and external control of the operating mechanism, and enhance the flexibility and controllability of the isolating switch.

[0042] Furthermore, the module fixing member 6 includes a support rod 601, and the end of the support rod 601 is provided with a threaded end 602. The module fixing member 6 adopts the design of the support rod 601 and the threaded end 602, and the support rod passes through each contact module in turn and is threadedly connected with the first circular hole 1051 of the connection module 5, so that the contact module is firmly fixed and easy to disassemble, which is convenient for the assembly and maintenance of the disconnector.

[0043] Furthermore, the connection module transmission member 4 includes a transmission sleeve 401, on which a first transmission connection hole 4011, a second transmission connection hole 4012, and an intermediate positioning rotation hole 4013 are formed; the transmission sleeve 401 and the transmission sheet 3 are connected in series one by one to transmit the manipulation of the operating mechanism module 7 to the contact module 1. The connection module transmission member 4 realizes the transmission of the manipulation instruction of the operating mechanism module 7 to the contact module 1 through the combined design of the transmission sleeve 401 and the transmission sheet 3. 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 plug-in cooperation between the transmission sheet and the connection sleeve, ensure the stability and accuracy of the transmission process.

[0044] Furthermore, adjacent transmission sleeves 401 are connected through transmission sheets 3, and connecting sleeves 4014 are installed at the bottom of both sides of the transmission sleeves 401. The top of the transmission sheet 3 is plugged with the connecting sleeve 4014 on the upper side, and the bottom of the transmission sheet 3 is plugged with the first transmission connection hole 4011 and the second transmission connection hole 4012 on the lower side. Adjacent transmission sleeves 401 are connected through transmission sheets 3, and connecting sleeves 4014 are installed at the bottom of both sides of the transmission sleeves. This design enables the transmission sheets to be firmly connected between the transmission sleeves, ensuring the effective transmission of the transmission force and improving the operating efficiency of the disconnector.

[0045] Furthermore, the support rod 601 passes through each contact module 1 in sequence, the first circular hole 1051 is provided with an internal thread, and the first circular hole 1051 of the connection module 5 of the threaded end 602 is threadedly connected. This design not only realizes the stable fixation of the contact module, but also facilitates the rapid disassembly and assembly of the contact module by rotating the support rod, thereby improving the maintainability of the disconnector.

[0046] Furthermore, the connection module 5 and the operating mechanism module 7 are connected and fixed by a mechanism module fixing member 8. This design enhances the connection strength between the connection module and the operating mechanism module, ensuring the accurate transmission of the operating instructions and the stable operation of the isolating switch.

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

[0048] When the modular isolating switch structure of the present invention is used, the number of required contact modules 1 is first determined according to actual needs, and these contact modules are stacked in sequence 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 terminal 103 and a second lead terminal 104. Then, a module fixing member 6 (a support rod 601 with a threaded end 602) is used to pass through each contact module 1 in sequence, and is threadedly connected to the first circular hole 1051 of the connecting module 5 to achieve a stable fixation of the contact module. This design makes the contact module easy to disassemble and replace, reducing maintenance costs and downtime.

[0049] The contact module transmission member 2 is installed in the middle of the adjacent contact modules 1, and the connection module transmission member 4 is installed in the middle of the connection module 5. These transmission members form an efficient transmission link through the combination design of the transmission sleeve 401 and the transmission plate 3. The transmission sleeve 401 is provided with a first transmission connection hole 4011, a second transmission connection hole 4012 and an intermediate positioning rotation hole 4013, which are plugged and matched with the transmission plate 3 to ensure the stability and accuracy of the transmission process. The adjacent transmission sleeves 401 are connected by the transmission plate 3, and the connection sleeves 4014 are installed at the bottom of both sides of the transmission sleeve. This design enables the transmission plate to be firmly connected between the transmission sleeves, ensuring the effective transmission of the transmission force.

[0050] The connection module 5 is connected and positioned with the operating mechanism module 7 through the second circular hole 1052. The operating mechanism module 7 is composed of an upper shell 702 and a lower shell 703, and an input transmission shaft 701 and an output transmission shaft 704 are installed inside, which are used to receive external operation instructions and transmit them to the contact module. The mechanism positioning hole 7021 and the mechanism connection hole 7022 on the upper shell 702, as well as the contact module positioning countersunk hole 7032 and the operating mechanism fixing hole 7033 on the lower shell 703, provide convenience for the installation and positioning of the operating mechanism. The connection module 5 and the operating mechanism module 7 are connected and fixed by the mechanism module fixing member 8, which enhances the connection strength between them and ensures the accurate transmission of the operation instructions.

[0051] When an external operation instruction is transmitted to the operating mechanism module 7 through the input transmission shaft 701, the instruction is converted into mechanical motion and transmitted to each contact module 1 through the connection module transmission member 4 and the contact module transmission member 2. The contact module performs a switch operation according to the received instruction to achieve isolation and connection of the power system. At the same time, the remote control interface hole 7031 on the lower shell of the operating mechanism module 7 allows remote operation and control, which improves the flexibility and controllability of the disconnector.

[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 disconnector.

[0053] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
