Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, and in particular to an electrical connection installation structure for substations. Background Technology

[0002] In modern power systems, substations serve as crucial hubs for power conversion and distribution, and their stable operation is of paramount importance. Electrical connections are the foundation for the coordinated operation of various electrical devices within a substation, and reliable electrical connection installation structures can ensure the stability and safety of current transmission.

[0003] Common electrical connection installation structures in substations mainly consist of connecting conductors, fastening components, and insulating parts. The connecting conductors, as the core carrier of current transmission, are typically made of highly conductive copper or aluminum, and their shape and size are customized according to the interfaces and current carrying requirements of different electrical equipment. Fastening components, such as bolts, nuts, and clamps, are responsible for reliably fixing the connecting conductors to the electrical equipment, ensuring a tight connection. Insulating parts surround the connection points, isolating current and preventing leakage. During operation, the connecting conductors, with their high conductivity, enable current flow between electrical equipment; the fastening components provide a stable mechanical connection, ensuring the connection does not loosen during operation; and the insulating parts maintain the electrical insulation performance of the entire installation structure, preventing current leakage and potential safety accidents. These components work together to ensure the safe and efficient operation of the substation's electrical connections.

[0004] Although the existing electrical connection installation structure meets the substation's operational needs to a certain extent, the following problems still exist: (1) Insufficient cable protection: After connection, the cables lack effective protection measures and are easily loosened by external force, leading to poor contact or even circuit breakage, affecting the stability of power transmission; exposed cables lack the ability to resist dust and moisture corrosion, and are in a harsh environment for a long time, the insulation layer is prone to aging and damage, greatly increasing the safety hazards such as short circuits. (2) Inconvenient installation and maintenance: The existing installation structure is relatively cumbersome in the installation and disassembly process, requiring more time and manpower, reducing work efficiency; when maintaining and replacing equipment, the disassembly and reinstallation process is complicated, increasing maintenance costs. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an electrical connection installation structure for substations, which aims to improve the problems of cables being easily pulled by external forces and lacking protection in the prior art, and to improve the stability and protection performance of cable connections.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electrical connection installation structure for a substation includes a housing, a fixing block fixedly connected to the front end of the housing, a protective mechanism provided at the top of the fixing block, a connector fixedly connected to the front end of the housing, an installation block fixedly connected to the outside of the housing, and a disassembly and assembly mechanism provided inside the installation block; the protective mechanism includes a sliding block, the outside of which is slidably connected to the inside of the fixing block, a limit clamp fixedly connected to the top of the sliding block, a spring fixedly connected to the bottom end of the limit clamp, a rotating block rotatably connected to the outside of the fixing block, and a limit clamp fixedly connected to the inside of the rotating block.

[0008] Preferably, the other end of the first spring is fixedly connected to the inside of the fixed block, and the outer sides of the second limiting clamp and the first limiting clamp are arc-shaped.

[0009] Preferably, the disassembly and assembly mechanism includes a fixed cylinder, the outside of which is slidably connected to the inside of the mounting block, a sliding cylinder is slidably connected inside the fixed cylinder, a rotating screw block is threadedly connected to the outside of the sliding cylinder, a connecting block is fixedly connected to the rear end of the sliding cylinder, a limit block is rotatably connected to the outside of the connecting block, a telescopic column is fixedly connected to the rear end of the connecting block, and a spring is sleeved on the outside of the telescopic column.

[0010] Preferably, a connecting rod is fixedly connected to the rear end of the first fixed cylinder, and a second fixed cylinder is fixedly connected to the rear end of the connecting rod.

[0011] Preferably, the front end of the second spring is fixedly connected to the rear end of the connecting block, and the other end of the second spring is fixedly connected to the inside of the second fixed cylinder.

[0012] Preferably, the rear end of the telescopic column is fixedly connected to the inside of the second fixed cylinder, and the outside of the limiting block is in contact with the outside of the first fixed cylinder.

[0013] Preferably, the external part of the connecting block is slidably connected to the inside of the second fixed cylinder, and the rear end of the rotating screw block contacts the front end of the first fixed cylinder.

[0014] Preferably, the rotating block has a slot inside, and the limiting block is slidably connected to the inside of the fixed cylinder.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, after the cable is connected to the connector, rotating the rotating block makes it fit against the fixed block, causing the limiting clamps one and two to clamp the cable. When the cable is pulled, the sliding block slides within the fixed block, and the spring cushions the sliding block, effectively resisting the cable being pulled and ensuring the stability of the cable-connector connection. Simultaneously, the rotating block protects the cable and connector from external damage. This design not only improves the reliability of the cable connection but also extends the service life of the cable and connector, reducing maintenance costs and power outage time caused by loose or damaged cables. Through the cushioning effect of the spring, the cable maintains a stable connection even in harsh environments, ensuring the continuity and safety of power transmission.

[0017] 2. In this utility model, during housing installation, pushing the sliding cylinder causes related components to slide the limiting block into the fixed cylinder, allowing the disassembly / assembly mechanism to slide into the two holes. After releasing the sliding cylinder, the spring pushes the connecting block, causing the limiting block to fit against the outside of the mounting column. Rotating the rotating screw block restricts the position of the sliding cylinder, completing the installation. During disassembly, rotating the rotating screw block in the opposite direction pushes the sliding cylinder to release the limiting block's restriction, achieving rapid disassembly / assembly of the entire connection structure and significantly improving work efficiency. This rapid disassembly / assembly design greatly simplifies the installation and maintenance process, reduces operating steps and time, and improves work efficiency. Especially in substation environments where frequent maintenance or equipment replacement is required, the rapid disassembly / assembly function can significantly reduce maintenance costs and improve equipment availability and reliability.

[0018] 3. This utility model, through the arc-shaped design of limiting clamp one and limiting clamp two, better conforms to the outer surface of the cable, improving the stability and reliability of clamping. Simultaneously, the elastic design of spring one and spring two not only provides a buffering effect but also enhances the mechanical stability of the entire structure. This design allows the electrical connection installation structure to maintain stable mechanical performance during long-term operation, reducing connection loosening or damage caused by mechanical vibration or external impact. By optimizing the mechanical structure, this utility model improves connection stability while also enhancing the overall durability of the equipment.

[0019] 4. This utility model, through the protective function of the rotating block, effectively prevents cables and connectors from being exposed to the external environment, reducing the corrosion of cables and connectors by dust, moisture, etc. Simultaneously, the coordinated design of the limiting block and the fixing cylinder ensures the firmness and reliability of the installation process. This design not only improves the safety of electrical connections but also reduces electrical faults caused by environmental factors. By enhancing insulation performance and protective functions, this utility model effectively reduces the probability of safety accidents such as short circuits and leakage currents, ensuring the stable operation of the substation.

[0020] 5. This utility model has excellent adaptability, making it suitable for cables and connectors of different specifications and models. By adjusting the dimensions of limit clamp one and limit clamp two, it can meet the clamping requirements of cables with different diameters. This highly adaptable design allows this utility model to be used in various substation environments, providing a reliable electrical connection solution for both small and large substations. By improving the versatility of the equipment, this utility model further reduces equipment procurement and maintenance costs, and improves the economic efficiency of the equipment.

[0026] 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.

[0027] Reference Figures 1 to 3This utility model provides an embodiment of an electrical connection installation structure for a substation, comprising a housing 1, which serves as the basic framework of the entire installation structure, accommodating and protecting the internal electrical components and providing a support platform for subsequent structural installation. A fixing block 2 is fixedly connected to the front end of the housing 1, primarily serving to connect and fix other components, providing a reliable connection point for the installation of a protection mechanism 3. A protection mechanism 3 is installed at the top of the fixing block 2, providing protection and buffering for cables connected to a connector 4, ensuring stable cable connections. A connector 4 is fixedly connected to the front end of the housing 1, a key component for achieving electrical connections, reliably connecting wires and other cables to transmit electrical energy. An installation block 5 is fixedly connected to the exterior of the housing 1, providing an interface for connecting the entire installation structure to external mounting columns and other structures, facilitating the fixing of the entire electrical connection installation structure in a suitable position. An assembly / disassembly mechanism 6 is installed inside the installation block 5, enabling rapid installation and disassembly of the entire installation structure, improving work efficiency and facilitating equipment maintenance and replacement.

[0028] The protection mechanism 3 includes a sliding block 31, which is externally slidably connected to the inside of the fixed block 2. The sliding block 31 can slide flexibly within the fixed block 2, providing a movable basis for subsequent buffering and limiting functions. The top of the sliding block 31 is fixedly connected to a limiting clamp 32, which is used to cooperate with a limiting clamp 35 to clamp and limit the cable, ensuring that the cable will not shake randomly during normal operation. A spring 33 is fixedly connected to the bottom end of the limiting clamp 32. The spring 33 can generate elastic deformation when subjected to external force, which plays a buffering role and reduces the tensile force on the cable. A rotating block 34 is rotatably connected to the outside of the fixing block 2. The rotating block 34 can rotate around the connection point with the fixing block 2 and is the key component for the protection mechanism to clamp and release the cable. A limiting clamp 35 is fixedly connected inside the rotating block 34. The limiting clamp 35 corresponds to the limiting clamp 32 and together completes the clamping and fixing work of the cable. The other end of the spring 33 is fixedly connected to the inside of the fixing block 2, so that the spring 33 forms a stable elastic structure inside the fixing block 2, which can continuously provide buffering force. The outer sides of the limiting clamp 35 and the limiting clamp 32 are arc-shaped. This arc design can better fit the outer surface of the cable and improve the stability and reliability of clamping.

[0029] Reference Figure 1 , Figure 2 and Figure 4The disassembly and assembly mechanism 6 includes a fixed cylinder 61, which is an important component of the disassembly and assembly mechanism 6. The external sliding cylinder 63 is slidably connected to the inside of the mounting block 5, allowing the entire disassembly and assembly mechanism to move flexibly within the mounting block 5. The internal sliding cylinder 63 is slidably connected to the fixed cylinder 61. The sliding cylinder 63 can slide within the fixed cylinder 61 and is a key component for enabling the limit block 67 to enter and exit the mounting post hole. The sliding cylinder 63 is used to achieve the installation and disassembly actions. The external threaded connection of the sliding cylinder 63 is a rotating screw block 62. The rotating screw block 62 can move outside the sliding cylinder 63 by rotating the thread, thereby restricting and releasing the position of the sliding cylinder 63, and playing the role of fixing and disassembling. The rear end of the sliding cylinder 63 is fixedly connected to a connecting block 64. The connecting block 64 is used to connect the sliding cylinder 63 and other components, such as the limit block 67 and the telescopic post 65, connecting the various components into a whole and ensuring the consistency of the action.

[0030] A limiting block 67 is rotatably connected to the outside of the connecting block 64. The limiting block 67 can rotate around the connection point with the connecting block 64, playing a crucial role in limiting and fixing during installation and disassembly. A telescopic column 65 is fixedly connected to the rear end of the connecting block 64. The telescopic column 65 can extend and retract within the fixed cylinder 69, cooperating with the spring 66 to provide power and buffer for the extension and retraction of the limiting block 67. The spring 66 is sleeved on the outside of the telescopic column 65. The spring 66 can store and release elastic potential energy when the telescopic column 65 extends and retracts, pushing the connecting block 64 and the limiting block 67 to move, realizing the installation and disassembly functions. The rear end of the fixed cylinder 61 is fixed. A connecting rod 68 is connected to the first fixed cylinder 61 and the second fixed cylinder 69, connecting the two fixed cylinders into a whole to ensure the stability of the entire disassembly and assembly mechanism. The second fixed cylinder 69 provides an installation space for components such as the telescopic column 65 and the second spring 66, and also cooperates with the hole of the mounting column to realize the entry and exit of the limit block 67. The front end of the second spring 66 is fixedly connected to the rear end of the connecting block 64, and the other end of the second spring 66 is fixedly connected to the inside of the second fixed cylinder 69, so that the second spring 66 forms an elastic structure between the connecting block 64 and the second fixed cylinder 69, which can effectively push the movement of the connecting block 64 and the limit block 67.

[0031] The rear end of the telescopic column 65 is fixedly connected to the inside of the fixed cylinder 69, ensuring that the telescopic column 65 can stably extend and retract within the fixed cylinder 69. The outside of the limiting block 67 is in contact with the outside of the fixed cylinder 61. During installation and disassembly, the position and state of the limiting block 67 directly affect the function of the entire disassembly and assembly mechanism. The outside of the connecting block 64 is slidably connected to the inside of the fixed cylinder 69, allowing the connecting block 64 to slide flexibly within the fixed cylinder 69, thereby driving the movement of components such as the limiting block 67. The rear end of the rotating screw block 62 is in contact with the front end of the fixed cylinder 61. By rotating the rotating screw block 62, it can be made to fit or separate from the front end of the fixed cylinder 61, thereby restricting or releasing the position of the sliding cylinder 63. The inside of the rotating block 34 has a slot. The outside of the limiting block 67 is slidably connected to the inside of the fixed cylinder 69. This structural design makes the connection between the various components tighter and the movement more coordinated.

[0032] Working principle: When the operator installs the housing 1, by aligning the hole of the mounting block 5 with the hole on the outside of the mounting column, the sliding cylinder 63 is pushed. The sliding cylinder 63 slides inside the first fixed cylinder 61, causing the telescopic column 65 to slide inside the second fixed cylinder 69. This allows the limiting block 67 to slide into the second fixed cylinder 69, at which point the entire disassembly and assembly mechanism 6 can be slid into the two holes. After adjusting the position, the pushing of the sliding cylinder 63 is released. The elastic potential energy accumulated by the second spring 66 will push the connecting block 64 to slide outward from the second fixed cylinder 69, thereby allowing... The limiting block 67 is externally attached to the outside of the mounting post. Then, by rotating the rotating screw 62, the rotating screw 62 will move to the outside of the sliding cylinder 63 until the rotating screw 62 is attached to the outside of the fixed cylinder 61, thus restricting the position of the sliding cylinder 63. At this time, the assembly of the mounting block 5 and the mounting post is completed. When disassembly is required, the rotating screw 62 is rotated in the opposite direction to remove the restriction on the sliding cylinder 63. Then the sliding cylinder 63 can be pushed to remove the restriction of the limiting block 67, thus completing the disassembly. The quick disassembly and assembly structure improves work efficiency.

[0033] After the operator connects the cable to the connector 4, the rotating block 34 is rotated so that the outside of the rotating block 34 fits against the outside of the fixed block 2. This causes the limit clamp 2 35 and the limit clamp 1 32 to clamp and limit the cable. When the cable is pulled, the sliding block 31 will slide inside the fixed block 2. At the same time, the spring 1 33 will buffer the sliding block 31 to achieve the effect of resisting pulling, effectively ensuring the stability of the connection between the cable and the connector 4.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
