Description

Technical Field

[0001] This utility model relates to the field of high-voltage power distribution equipment technology, specifically a compact GIS combined electrical appliance layout structure, which is suitable for scenarios such as the expansion of ultra-high voltage substations. Background Technology

[0002] In the expansion of GIS (Gas Insulation System) in ultra-high voltage substations, the conventional approach requires de-energizing and dismantling the existing GIS equipment, removing the busbar covers, exposing the original conductors, and then installing new units and reconnecting them. This process heavily relies on large lifting equipment for precision hoisting and connection, and the on-site welding and installation operations are time-consuming. To maintain the SF6 gas insulation performance of the gas chamber, temporary dust-proof sheds must be erected and strict environmental dust control measures implemented. The entire process is time-consuming, results in significant power outage losses, and carries a high risk of equipment damage or seal failure due to human error. Utility Model Content

[0003] This utility model overcomes the shortcomings of the prior art and proposes a compact GIS combined electrical appliance layout structure; it solves the problem that current GIS expansion projects and other projects heavily rely on large lifting equipment for precision hoisting and docking, and that on-site welding and installation operations take a long time.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A compact GIS combined electrical appliance layout structure includes multiple rigid base plate units fixed side by side. Multiple module mounting frames are fixed side by side on the multiple rigid base plate units, and a GIS module is installed on each module mounting frame. Unit T-shaped slide rails are fixedly connected to the back side of the multiple rigid base plate units. T-shaped trolleys are slidably connected in the T-shaped slide grooves on the upper side of the multiple unit T-shaped slide rails. An auxiliary lifting mechanism and a positive pressure dustproof mechanism are provided at the upper end of the T-shaped trolleys.

[0005] Furthermore, the rigid base plate unit has multiple docking and positioning grooves at equal intervals, and ball bearing wheels are fixedly connected to the bottom sides of the module mounting base at the corresponding docking and positioning groove positions.

[0006] Furthermore, the top surface of the module mounting base is threaded with a fixing screw on the front side of the ball bearing wheel rows on both sides. The bottom of the fixing screw is rotatably connected to a supporting friction foot, and the bottom of the supporting friction foot is fixedly connected with a rubber anti-slip pad. The total thickness of the supporting friction foot and the rubber anti-slip pad is less than the depth of the docking positioning groove.

[0007] Furthermore, the auxiliary lifting mechanism includes a translational lifting rail, on which a high-precision electric hoist is slidably connected.

[0008] Furthermore, the bottom of each end of the sliding rail is fixedly connected to a rear support column and a front support column, respectively. The bottom of the rear support column is fixedly connected to the T-shaped trolley with its bottom facing down, and the bottom of the front support column is fixedly connected to a base with casters.

[0009] Furthermore, the positive pressure dustproof mechanism includes a dustproof mounting bracket, on which a HEPA filter unit is fixedly connected. A flexible cover is fitted onto the upper side of the dustproof mounting bracket, and the center of the flexible cover is connected to the air outlet of the HEPA filter unit.

[0010] Furthermore, the dustproof mounting bracket has a beam structure, and both sides of the dustproof mounting bracket are fixedly connected to the rear support column and the front support column through uprights.

[0011] Furthermore, the flexible cover is a frustoconical flexible dustproof cover with the large end facing down, and the bottom edge of the flexible cover is fixedly connected with a magnetic rubber edge.

[0012] Furthermore, the flexible cover fabric has multiple operating holes with sealed gloves in the middle of its sidewall.

[0013] Furthermore, the width of the rigid base plate unit is equal to the width of the module mounting base, and the number of rigid base plate units is one more than the number of module mounting bases. Adjacent rigid base plate units are staggered and overlapped, and then fixedly connected by bolts. The center of the module mounting base is set to correspond to the overlap seam of the adjacent rigid base plate units.

[0014] The beneficial effects of this utility model compared to the prior art are as follows: 1. This utility model securely fixes multiple rigid base plate units side-by-side on a designated surface in the substation. The GIS module is then firmly mounted on a module mounting frame, ensuring the reliability and safety of the electrical connections. Subsequently, using the unit T-shaped slide rails on the back of the rigid base plate units, the T-shaped trolley is slid to the desired position. The design of the T-shaped trolley allows for easy and stable movement on the slide rails, facilitating position adjustments to adapt to different installation requirements. An auxiliary lifting mechanism located at the top of the T-shaped trolley assists workers in easily lifting and positioning heavy components, significantly reducing labor intensity and improving work efficiency.

[0015] 2. This utility model's positive pressure dustproof mechanism continuously blows air purified by a HEPA filter unit into the device, creating a positive pressure environment. This effectively prevents external dust and pollutants from entering, protects the connection of the GIS module's upper air chamber, and extends the equipment's service life. The entire device has a compact structure and a reasonable layout, meeting the space utilization requirements of ultra-high voltage substation expansion while ensuring the safety and stability of equipment operation.

[0016] 3. When expansion is required, this utility model only requires adding rigid base plate units and modular mounting frames with GIS modules installed in sequence to quickly complete the substation expansion work without large-scale modifications to the original structure, greatly shortening the expansion cycle and reducing expansion costs. Moreover, all components in this layout structure adopt standardized design, which facilitates production, transportation and installation, further improving the efficiency and reliability of substation expansion.

[0019] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, this utility model will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it. The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0020] See Figures 1 to 3 This embodiment proposes a compact GIS combined electrical appliance layout structure for the expansion of ultra-high voltage substations, including multiple rigid base plate units 1, which are fixed side by side on the ground of the substation. Multiple docking positioning grooves 2 are equally spaced on the rigid base plate units 1. Multiple module mounting frames 3 are fixed side by side on the multiple rigid base plate units 1, and a GIS module 5 is installed on each module mounting frame 3. Unit T-shaped slide rails 6 are fixedly connected to the back side of the multiple rigid base plate units 1. T-shaped trolleys 7 are slidably connected in the T-shaped slide grooves on the upper side of the multiple unit T-shaped slide rails 6. An auxiliary lifting mechanism and a positive pressure dustproof mechanism are provided at the upper end of the T-shaped trolleys 7.

[0021] In use, multiple rigid base plate units 1 are securely fixed side-by-side on the designated ground surface of the substation. The GIS module 5 is then securely mounted on the module mounting frame 3, ensuring the reliability and safety of the electrical connections. Subsequently, using the unit T-shaped slide rails 6 on the back side of the rigid base plate unit 1, the T-shaped trolley 7 is slid to the desired position. The design of the T-shaped trolley 7 allows it to move easily and stably on the slide rails, facilitating position adjustments to adapt to different installation requirements. An auxiliary lifting mechanism located at the top of the T-shaped trolley 7 assists workers in easily lifting and positioning heavy components, significantly reducing labor intensity and improving work efficiency. Simultaneously, the positive pressure dustproof mechanism continuously blows air purified by the HEPA filter unit into the device, creating a positive pressure environment that effectively prevents external dust and contaminants from entering, protecting the connection of the upper air chamber of the GIS module 5 and extending the equipment's service life. The entire device features a compact structure and rational layout, meeting the requirements for efficient space utilization in ultra-high voltage substation expansion while ensuring the safety and stability of equipment operation. When expansion is needed, only the rigid base plate unit 1 and the module mounting frame 3 with the GIS module 5 installed need to be added sequentially to quickly complete the substation expansion without requiring large-scale modifications to the original structure, significantly shortening the expansion cycle and reducing costs. Furthermore, all components in this layout adopt standardized designs, facilitating production, transportation, and installation, further improving the efficiency and reliability of substation expansion.

[0022] In this embodiment, preferably, the width of the rigid base plate unit 1 is equal to the width of the module mounting base 3, and the number of rigid base plate units 1 is one more than the number of module mounting bases 3. Adjacent rigid base plate units 1 are staggered and overlapped, and then fixed together with bolts. The center of the module mounting base 3 is set to correspond to the overlap joint of the adjacent rigid base plate units 1. Through the staggered overlap design, the connection between the rigid base plate units 1 can be made more stable, enhancing the load-bearing capacity of the entire arrangement structure. At the same time, the center of the module mounting base 3 is set to correspond to the overlap joint, making the stress more uniform. During installation and use, it can effectively avoid structural deformation or damage caused by uneven stress, ensuring the stable operation of the GIS module 5.

[0023] In this embodiment, preferably, the auxiliary lifting mechanism includes a translational lifting rail 11, on which a high-precision electric hoist 12 is slidably sleeved. A rear support column 8 and a front support column 10 are fixedly connected to the bottom of both ends of the translational lifting rail 11, respectively. The bottom of the rear support column 8 is fixedly connected to a T-shaped trolley 7 facing downwards, and the bottom of the front support column 10 is fixedly connected to a base 9 with casters. The translational lifting rail 11 provides a stable moving track for the high-precision electric hoist 12, enabling it to move precisely in the horizontal direction, thereby achieving precise lifting of the GIS module 5. The high-precision electric hoist 12 has a powerful lifting capacity, easily handling the lifting needs of heavy components, and is easy to operate and safe and reliable. The rear support column 8 and the front support column 10 are fixedly fixed to the bottom of both ends of the translational lifting rail 11, providing stable support for the entire auxiliary lifting mechanism. The rear support column 8 is fixedly connected to the T-shaped trolley 7, allowing the auxiliary lifting mechanism to move along the T-shaped trolley 7 on the unit T-shaped slide rail 6, further enhancing its flexibility and applicability. The base 9 with casters at the bottom of the front support column 10 facilitates the movement and positioning of the entire auxiliary lifting mechanism on the ground, improving work efficiency.

[0024] In this embodiment, preferably, the positive pressure dustproof mechanism includes a dustproof fixing frame 13, which is a beam structure. The dustproof fixing frame 13 is fixedly connected to the rear support column 8 and the front support column 10 on both sides via uprights. A HEPA filter unit 14 is fixedly connected to the upper center of the dustproof fixing frame 13. A flexible cover 15 is sleeved on the upper side of the dustproof fixing frame 13, and the center of the flexible cover 15 communicates with the air outlet of the HEPA filter unit 14. The dustproof fixing frame 13 serves as the supporting structure for the entire positive pressure dustproof mechanism. Its fixed connection to the rear support column 8 and the front support column 10 via the uprights on both sides ensures the stability and reliability of the mechanism. The HEPA filter unit 14, fixed to the upper center of the dustproof fixing frame 13, effectively filters the air entering the device, removing dust and contaminants and ensuring the cleanliness of the air chamber. The flexible cover 15 is fitted onto the upper side of the dustproof mounting bracket 13, with its center connected to the air outlet of the HEPA filter unit 14. This allows filtered air to be evenly blown into the device, creating a positive pressure environment and further preventing external dust from entering. This design not only ensures dustproof performance but also makes the airflow distribution inside the device more reasonable, which is beneficial to the stable operation of the GIS module 5.

[0025] In this embodiment, preferably, the flexible cover 15 is a frustoconical flexible dustproof cover with the larger end facing downwards. A magnetic rubber edge is fixedly connected to the bottom edge of the flexible cover 15, and multiple operation holes for sealing gloves are provided in the middle of the side wall of the flexible cover 15. The flexible cover 15 adopts a frustoconical design with the larger end facing downwards. This shape can better cover the upper area of ​​the device, forming an effective positive pressure dustproof space. The magnetic rubber edge fixed to its bottom edge can fit tightly against the edge of the device, further enhancing the dustproof effect and preventing dust from entering through edge gaps. The multiple operation holes for sealing gloves in the middle of the side wall facilitate necessary operation and maintenance by personnel during device operation. At the same time, the design of the sealing gloves ensures a tight seal during operation, preventing disruption of the positive pressure environment inside the device and ensuring that the GIS module 5 can continue to operate in a clean and stable environment.

[0026] In this embodiment, preferably, ball bearing rows 4 are fixedly connected to the middle of the bottom two sides of the module mounting base 3, corresponding to the docking positioning grooves 2. The top surface of the module mounting base 3 is threaded with fixing screws 16 on the front sides of the ball bearing rows 4 on both sides. Supporting friction feet 17 are rotatably connected to the bottom of the fixing screws 16, and rubber anti-slip pads are fixedly connected to the bottom of the supporting friction feet 17. The total thickness of the supporting friction feet 17 and the rubber anti-slip pads is less than the depth of the docking positioning grooves 2. The design of the ball bearing rows 4 makes the module mounting base 3 move more smoothly, reduces friction, and facilitates the position adjustment and installation of the GIS module 5 by the operators. When the module mounting base 3 moves to the designated position, rotating the fixing screws 16 allows the supporting friction feet 17 to move downwards until the rubber anti-slip pads are in close contact with the ground, providing stable support. Since the total thickness of the supporting friction foot 17 and the rubber anti-slip pad is less than the depth of the docking positioning groove 2, while ensuring stable support, it will not affect the normal docking of the module mounting base 3 and the docking positioning groove 2 on the rigid base plate unit 1, thus ensuring the stability and reliability of the entire layout structure and providing a solid foundation for the safe operation of the GIS module 5. During equipment installation, the level of the module mounting base 3 can be adjusted by rotating the fixing screw 16 to ensure that the GIS module 5 installed on it is in a horizontal position. This is crucial for the normal operation of the GIS module 5. The internal electrical components and insulation structure of the GIS module 5 have high requirements for installation levelness; poor levelness may lead to problems such as poor electrical connections and decreased insulation performance, affecting the stability and service life of the equipment. This design allows for convenient and quick module installation through a simple rotation of the fixing screw 16.

It should not be considered that the specific embodiments of the present invention are limited to this. For those skilled in the art, several simple deductions or substitutions can be made without departing from the present invention, and all such deductions or substitutions should be considered to fall within the scope of patent protection determined by the submitted claims.
