Description

Technical Field

[0001] This invention relates to the field of switchgear technology, and in particular to an outdoor fully enclosed insulated ring network switchgear. Background Technology

[0002] An insulated ring network switchgear is an electrical device consisting of a set of high-voltage switchgear installed in a steel plate metal cabinet or assembled into a modular ring network power supply unit. Its core components are load switches and fuses. It has advantages such as simple structure, small size, low price, improved power supply parameters and performance, and enhanced power supply safety. It is widely used in distribution substations and prefabricated substations in load centers such as urban residential areas, high-rise buildings, large public buildings, and factories.

[0003] The insulated ring network switchgear mainly consists of a cabinet, busbar compartment, switch compartment, and cable compartment. It uses solid insulation materials or gaseous insulation media (such as SF6 and its alternative gases) to isolate live components, ensuring insulation performance and operational safety. The busbar compartment connects the busbars of each circuit, enabling power collection and distribution. The switch compartment houses core switching elements such as circuit breakers and load switches, responsible for circuit opening and closing control. The cable compartment is used for cable connection and fixing. During operation, the operating mechanism drives the switching elements, controlling circuit switching in scenarios requiring maintenance, fault isolation, or load switching. The insulation medium effectively prevents electrical breakdown, ensuring stable equipment operation and enabling flexible scheduling and reliable power supply of the power distribution system.

[0004] In existing technologies, some insulated ring network switchgear has significant defects: in terms of structural design, it often uses hinged doors for enclosure. After long-term use, the screws on the hinges are prone to loosening and misalignment, causing the gaps in the door panels to widen and severely reducing the sealing performance. In practical applications, especially in harsh environments such as sandstorms and heavy rain, external dust and rainwater can seep into the switchgear through the gaps, causing electrical components to become damp and dusty. This not only accelerates equipment aging but also easily leads to faults such as short circuits and poor contact, resulting in frequent shutdowns for maintenance. At the same time, traditional switchgear maintenance requires disassembly of the cabinet, which is cumbersome and time-consuming, increasing maintenance costs and seriously affecting the stability and continuity of power supply. Therefore, to address these shortcomings, a new type of prefabricated substation for new energy is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an outdoor fully enclosed insulated ring network switchgear, which solves the problems of traditional insulated ring network switchgear where the hinges connecting the door panel screws are prone to loosening and misalignment, resulting in decreased sealing performance, inability to withstand harsh environmental conditions, damage to internal equipment, frequent failures, and difficulties in disassembling and repairing the cabinet, as well as high maintenance costs.

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

[0007] An outdoor fully enclosed insulated ring main switchgear includes a base, an opening and closing mechanism at the top of the base, an inlet mechanism inside the opening and closing mechanism, a shielding canopy fixedly connected to the top of the opening and closing mechanism, and a cleaning mechanism outside the opening and closing mechanism. The opening and closing mechanism includes multiple fixed frames, the bottom ends of which are fixedly connected to the top of the base. Two of the fixed frames are slidably connected to a sliding rod inside, a fixed rod is fixedly connected to the outside of the sliding rod, and a protective shell is fixedly connected to the outside of the fixed rod. A back plate is fixedly connected to the top of the base, a drive assembly is disposed inside the back plate, a moving column is fixedly connected inside the sliding rod, and a sealing gasket is fixedly connected inside the base.

[0008] Preferably, the movable column is externally slidably connected to the inside of the back plate, and the fixed frame has a sliding groove inside.

[0009] Preferably, the outer part of the protective shell is slidably connected to the inside of the base, and the bottom end of the protective shell contacts the top end of the sealing gasket.

[0010] Preferably, the drive assembly includes a motor, the bottom end of which is fixedly connected to the top end of the base, and the drive end of the motor is fixedly connected to a stud, the external thread of which is connected to the interior of the movable column.

[0011] Preferably, the infeed mechanism includes a sliding block, the sliding block is slidably connected to the outside of the back plate, a fixed cylinder is fixedly connected to the rear end of the sliding block, an inner cylinder is fixedly connected to the inside of the fixed cylinder, a threaded sleeve is threadedly connected to the outside of the fixed cylinder, a plurality of fixed rods are slidably connected to the inside of the threaded sleeve, a fixed rod is fixedly connected to the outside of the fixed rods, a moving ring is fixedly connected to the outside of the fixed rods, a sealing ring is fixedly connected to the outside of the moving ring, and a buffer assembly is provided inside the back plate.

[0012] Preferably, the buffer assembly includes a second telescopic column, the second telescopic column being externally fixedly connected to the inside of the back plate, and a second spring being sleeved on the outside of the second telescopic column.

[0013] Preferably, one end of the telescopic column two, which is close to the sliding block, is fixedly connected to the outside of the sliding block; one end of the spring two is fixedly connected to the inside of the protective shell; and the other end of the spring two is fixedly connected to the outside of the sliding block.

[0014] Preferably, the outer side of the movable ring is in contact with the inner side of the inner cylinder, and the outer side of the sealing ring is in contact with the inner side of the inner cylinder.

[0015] Preferably, the cleaning mechanism includes a fixed block, which is externally fixedly connected to the rear end of the back plate. A second fixed frame is slidably connected to the outside of the fixed block. Two cleaning brushes are rotatably connected inside the second fixed frame. Two first movable blocks are slidably connected inside the second fixed frame. Each of the first movable blocks is rotatably connected to another cleaning brush. A first telescopic column is fixedly connected to the outside of the first movable block. A first spring is sleeved on the outside of the first telescopic column. A second fixed fixed frame is a sliding column.

[0016] Preferably, one end of the telescopic column away from the moving block is fixedly connected to the inside of the fixed frame, one end of the spring is fixedly connected to the inside of the fixed frame, and the other end of the spring is fixedly connected to the end of the moving block that is close to the telescopic column. A sliding groove is provided at the rear end of the back plate, and the outside of the sliding column is slidably connected to the inside of the sliding groove.

[0017] In summary, the present invention has at least one of the following beneficial technical effects:

[0018] 1. This invention uses a starter motor to drive the stud to rotate, which, through a moving column and sliding rod, enables the protective shell to automatically rise and fall. This allows for convenient opening and closing of the switchgear, and operators can perform maintenance and repairs from three directions without disassembling the cabinet as in traditional methods, significantly reducing maintenance difficulty and workload. When the switchgear is closed, the protective shell compresses the sealing gasket to form a tight seal, effectively preventing dust and moisture from entering and ensuring the stable operation of internal electrical components in harsh outdoor environments, thus significantly extending the equipment's service life.

[0019] 2. During the process of raising the protective housing to open the switchgear, this invention drives the fixed frame to slide left and right, allowing the cleaning brush to automatically scrape and clean the front and sides of the protective housing. The moving block, in conjunction with the spring, ensures that the cleaning brush always stays in contact with the surface of the protective housing, maintaining efficient cleaning even when the fixed frame is reciprocating. This automatic cleaning mechanism requires no manual intervention, effectively reducing the time and labor costs of manual cleaning, keeping the switchgear casing clean, and reducing the risk of equipment failure due to dirt accumulation.

[0020] 3. After the cable is placed into the inner cylinder, the rotating threaded sleeve drives the relevant components to move. By utilizing the gradually changing inner diameter of the inner cylinder and the elastic deformation of the sealing ring, a tight seal can be achieved for cables of different thicknesses to a certain extent, preventing moisture and dust from entering the connection. When the cable is pulled by an external force, the sliding block slides and compresses the spring. The reaction force generated by the spring deformation can weaken the pulling force, buffer the impact of external force, effectively reduce the risk of cable loosening and falling off, significantly improve the stability and reliability of cable connection in the distribution cabinet, and ensure the safety of power transmission.

[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 The present invention will be further described in detail below.

[0031] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 4This invention provides an outdoor fully enclosed insulated ring network switchgear, including a base 1 made of high-strength corrosion-resistant steel, providing a stable foundation for the entire switchgear. An opening / closing mechanism 2 is installed at the top of the base 1, which automatically opens and closes the switchgear for easy equipment inspection and maintenance. An inlet mechanism 5 is installed inside the opening / closing mechanism 2, responsible for cable connection and sealing, ensuring the stability and sealing of the electrical connection. A shielding canopy 4 is fixedly connected to the top of the opening / closing mechanism 2, effectively blocking direct sunlight and rain / snow, providing additional protection for the switchgear. A cleaning mechanism 3 is installed outside the opening / closing mechanism 2, which automatically cleans the outer casing during the opening and closing process, keeping the equipment clean. To reduce manual maintenance costs, the opening and closing mechanism 2 includes multiple fixed frames 21, which are vertically fixed to the top of the base 1 to form a stable support frame, providing installation and sliding guidance for components such as the sliding rod 22. The sliding rod 22 is slidably connected inside two of the fixed frames 21. The sliding rod 22 can slide smoothly in the sliding groove 23 of the fixed frame 21 to realize the lifting drive of the protective shell 27. The external fixed connection of the sliding rod 22 is a fixed rod 26, which is used to connect the sliding rod 22 and the protective shell 27 to ensure that the two move synchronously. The external fixed connection of the fixed rod 26 is a protective shell 27, which is the core protective component of the switch cabinet and can isolate the influence of the external environment on the internal equipment.

[0032] Specifically, the opening and closing mechanism 2 achieves automatic opening, closing, and sealing of the switchgear through the coordinated operation of multiple components. Multiple fixed brackets 21 form a stable frame on the base 1, guiding the sliding rod 22. The sliding rod 22 slides along the sliding groove 23 of the fixed bracket 21, and drives the protective shell 27 to rise and fall via the fixed rod 26, so that the switchgear can be automatically opened for easy maintenance. When closed, the protective shell 27 presses down and squeezes the sealing gasket 28 to form a tight protection, isolating external dust and moisture, ensuring the stable operation of internal equipment, avoiding the tediousness of manual disassembly and maintenance, and improving the convenience of maintenance and the protective performance of the equipment.

[0033] A back plate 29 is fixedly connected to the top of the base 1. A drive assembly 25 is housed inside the back plate 29. The back plate 29 provides installation space for the drive assembly 25 and other components, and supports and guides components such as the moving column 24. The drive assembly 25 provides power to the opening and closing mechanism 2, enabling the automatic lifting and lowering of the protective shell 27. A moving column 24 is fixedly connected inside the sliding rod 22. The moving column 24 cooperates with the drive assembly 25 to convert rotational motion into linear motion, driving the sliding rod 22 to slide. A sealing gasket 28 is fixedly connected inside the base 1. The sealing gasket 28 is made of highly elastic and weather-resistant material to enhance the sealing of the switchgear. The moving column 24 is externally slidably connected to the inside of the back plate 29, ensuring the stability and accuracy of the moving column 24's movement. The fixed bracket 21... The internal sliding groove 23 provides a precise sliding track for the sliding rod 22. The external protective shell 27 is slidably connected to the inside of the base 1. The protective shell 27 can slide up and down along the track inside the base 1. The bottom end of the protective shell 27 contacts the top end of the sealing gasket 28. When the protective shell 27 descends and closes, it achieves a good sealing effect by squeezing the sealing gasket 28. The drive assembly 25 includes a motor 251. The motor 251 is a high-torque, low-energy-consumption model that provides stable power for the opening and closing of the switch cabinet. The bottom end of the motor 251 is fixedly connected to the top end of the base 1 to ensure that the motor 251 is installed firmly. The drive end of the motor 251 is fixedly connected to a stud 252. The stud 252 rotates under the drive of the motor 251 and cooperates with the moving column 24 to realize linear motion conversion.

[0034] Specifically, the back plate 29, in conjunction with the drive assembly 25 and the moving column 24, converts rotational power into linear motion to drive the opening and closing mechanism 2. The back plate 29 provides installation space for the drive assembly 25 and supports the sliding of the moving column 24. The motor 251 drives the stud 252 to rotate, and the stud 252 engages with the moving column 24 threadedly, causing the moving column 24 to slide within the back plate 29, thereby moving the sliding rod 22 and achieving automatic lifting and lowering of the protective shell 27. This process ensures stable power transmission, guaranteeing precise and efficient opening and closing actions, and providing reliable power support for the automated operation of the switchgear.

[0035] Please see the appendix Figure 2 Appendix Figure 5 and attached Figure 6The cable inlet mechanism 5 includes a sliding block 56, which can slide flexibly inside the back plate 29, providing buffering and displacement adjustment functions for cable connection. A fixed cylinder 51 is fixedly connected to the rear end of the sliding block 56. The fixed cylinder 51 provides an installation base for components such as the inner cylinder 52 and threaded sleeve 53. The inner cylinder 52 is fixedly connected inside the fixed cylinder 51, and is used to accommodate cables. Its gradually changing inner diameter design achieves sealing adaptation for cables of different specifications. A threaded sleeve 53 is threadedly connected to the outside of the fixed cylinder 51. The threaded sleeve 53, through rotational movement, drives components such as the second fixed rod 54 to move, achieving clamping and sealing of the cable. Multiple second fixed rods 54 are slidably connected inside the threaded sleeve 53. Driven by the threaded sleeve 53, the fixed rod 3 55, the moving ring 57, and the sealing ring 58 move. The fixed rod 3 55 is slidably connected to the outside of the fixed rod 2 54. The fixed rod 3 55 is used to transmit the movement of the fixed rod 2 54 and support the moving ring 57 and the sealing ring 58. The moving ring 57 is fixedly connected to the outside of the fixed rod 3 55. The moving ring 57 can move with the fixed rod 3 55 and assist the sealing ring 58 in achieving the sealing function. The sealing ring 58 is fixedly connected to the outside of the moving ring 57. The sealing ring 58 is made of highly elastic sealing material, which can tightly fit the cable and achieve a good sealing effect. The back plate 29 is equipped with a buffer component 59. The buffer component 59 is used to reduce the impact of external forces on the cable and improve the connection stability.

[0036] Specifically, the cable inlet mechanism 5 achieves stable cable connection and sealing through a unique structure. The sliding block 56 provides cushioning by sliding within the back plate 29, while the fixed cylinder 51 supports components such as the inner cylinder 52 and the threaded sleeve 53. Rotating the threaded sleeve 53 moves the second fixed rod 54, which in turn drives the third fixed rod 55, the moving ring 57, and the sealing ring 58. Utilizing the gradually changing inner diameter of the inner cylinder 52, combined with the elastic deformation of the sealing ring 58, it adapts to cables of different thicknesses, achieving a tight seal. Simultaneously, the second spring 592 in the buffer assembly 59 absorbs the cable's pulling force, reducing the impact of external forces, ensuring a stable cable connection, and improving the safety and reliability of the electrical connection.

[0037] The buffer assembly 59 includes a telescopic column 591, which provides structural support for the buffer assembly 59 and limits the movement range of the sliding block 56. The telescopic column 591 is externally fixedly connected to the inside of the back plate 29 to ensure a secure installation. A spring 592 is sleeved on the outside of the telescopic column 591. The spring 592 absorbs and releases energy through elastic deformation to buffer the external force on the cable. One end of the telescopic column 591, which is close to the sliding block 56, is fixedly connected to the outside of the sliding block 56, so that the sliding block 56 and the buffer assembly 59 are linked. One end of the spring 592 is fixedly connected to the inside of the protective shell 27, and the other end is fixedly connected to the outside of the sliding block 56, balancing the tension on the cable through elastic force. The outside of the moving ring 57 contacts the inside of the inner cylinder 52, and the auxiliary sealing ring 58 achieves a seal. The outside of the sealing ring 58 contacts the inside of the inner cylinder 52 and tightly fits the cable through its own deformation to achieve a waterproof and dustproof seal.

[0038] Specifically, the buffer assembly 59 relies on the cooperation of the telescopic column 591 and the spring 592 to enhance the stability of the cable connection. The telescopic column 591 is fixed to the back plate 29, limiting the movement range of the sliding block 56 and providing support; the two ends of the spring 592 are respectively connected to the protective shell 27 and the sliding block 56. When the cable is pulled by an external force, the sliding block 56 slides and compresses the spring 592. The spring absorbs energy through elastic deformation, offsetting part of the pulling force, balancing the force on the cable, reducing the impact of external force on the connection part, effectively protecting the cable connection, and extending the service life of the equipment.

[0039] Please see the appendix Figure 3 Appendix Figure 7 and attached Figure 8The cleaning mechanism 3 includes a fixing block 31, which is fixed to the rear end of the back plate 29, providing installation support for components such as the second fixing frame 32. The second fixing frame 32 is slidably connected to the outside of the fixing block 31, and can slide left and right on the fixing block 31, driving the cleaning brush 38 to clean the protective shell 27. Two cleaning brushes 38 are rotatably connected inside the second fixing frame 32, used to clean the front surface of the protective shell 27. Two moving blocks 35 are slidably connected inside the second fixing frame 32, and can slide within the second fixing frame 32 to ensure that the cleaning brushes 38 always fit against the sides of the protective shell 27. Each of the two moving blocks 35 is rotatably connected to another cleaning brush 38, used to clean the left and right sides of the protective shell 27. A telescopic column 36 is fixedly connected to the outside of the moving blocks 35, providing sliding guidance for the moving blocks 35 and assisting the spring 37 in adjusting the pressure of the cleaning brushes 38. The telescopic column 36 is fitted with a spring 37. The spring 37 maintains the pressure of the cleaning brush 38 on the protective shell 27 through elastic deformation, ensuring the cleaning effect. The fixed frame 32 is fixedly connected to a sliding column 33 inside. The sliding column 33 cooperates with the sliding groove 34 of the back plate 29 to realize the left and right sliding of the fixed frame 32. The end of the telescopic column 36 away from the moving block 35 is fixedly connected to the inside of the fixed frame 32 to ensure that the telescopic column 36 is installed firmly. One end of the spring 37 is fixedly connected to the inside of the fixed frame 32, and the other end is fixedly connected to the end of the moving block 35 near the telescopic column 36. The elastic force pushes the moving block 35 to make the cleaning brush 38 fit tightly against the protective shell 27. The rear end of the back plate 29 is provided with a sliding groove 34, which provides a sliding track for the sliding column 33 and guides the movement trajectory of the fixed frame 32. The outside of the sliding column 33 is slidably connected to the inside of the sliding groove 34 to ensure that the fixed frame 32 slides smoothly and accurately.

[0040] Specifically, the cleaning mechanism 3 utilizes mechanical linkage to achieve automatic cleaning of the protective shell 27. When the protective shell 27 is raised or lowered, the sliding column 33 of the fixed frame 22 slides along the sliding groove 34 of the back plate 29, causing the fixed frame 22 to move back and forth. The cleaning brush 38 at the front end of the fixed frame 22 scrapes the front of the protective shell 27, while the moving blocks 35 on both sides, under the action of the spring 37, drive the cleaning brush 38 to slide close to the side of the protective shell 27. The elasticity of the spring 37 ensures that the cleaning brush 38 maintains appropriate pressure, ensuring cleaning effectiveness. The entire process requires no manual intervention, automatically removing dust and debris from the surface of the protective shell 27, reducing maintenance costs, and maintaining the clean appearance and good operating condition of the equipment.

[0041] Working principle: When the switchgear needs to be switched on or off, the motor 251 is started. The motor 251 drives the stud 252 to rotate inside the moving column 24, causing the moving column 24 to slide inside the back plate 29. This causes the sliding rod 22 to slide inside the fixed frame 21. Through the sliding of the sliding rod 22, the fixed rod 26 drives the protective shell 27 to rise and fall, thus opening and closing the entire switchgear. After opening and closing, the operator can inspect and maintain the switchgear from three sides, thus avoiding the trouble of traditional manual disassembly and maintenance. When closed, the bottom end of the protective shell 27 contacts the top end of the sealing gasket 28, thereby squeezing the sealing gasket 28 to achieve a sealing effect, ensuring complete isolation between the inside of the switchgear and the outside world, effectively preventing the entry of dust and moisture, extending the service life of the equipment, and ensuring stable operation of the equipment in harsh environments.

[0042] As the protective shell 27 rises, the sliding column 33 inside the fixing frame 2 32 slides inside the sliding groove 34, causing the fixing frame 2 32 to slide back and forth. This allows the cleaning brush 38 at the front end of the fixing frame 2 32 to scrape the front end of the protective shell 27. At the same time, the cleaning brushes 38 at both ends of the fixing frame 2 32 clean the left and right sides of the protective shell 27. Meanwhile, the moving block 1 35 slides inside the fixing frame 2 32, and the spring 1 37 compresses and expands during the movement of the moving block 1 35. This ensures that the cleaning brushes 38 remain in contact with both sides of the protective shell 27 as the fixing frame 2 32 moves left and right, guaranteeing a thorough cleaning effect. By automatically cleaning the exterior of the protective shell 27 with the cleaning brushes 38 as the protective shell 27 rises, the time required for manual cleaning is reduced.

[0043] When connecting cables to the distribution cabinet, the outer part of the cable is slid into the inner cylinder 52, and then the threaded sleeve 53 is rotated, causing the threaded sleeve 53 to rotate outside the fixed cylinder 51. This causes the fixed rod 54 to move the fixed rod 55, the moving ring 57, and the sealing ring 58 as a whole. Because the inner diameter of the inner cylinder 52 is a gradient design, when the threaded sleeve 53 rotates outside the fixed cylinder 51, the sealing ring 58 will contact the inner wall of the inner cylinder 52. At the same time, the deformation capability of the sealing ring 58 itself allows it to adapt to cables of different thicknesses to a certain extent, thereby achieving a sealing effect for cables of different thicknesses. Meanwhile, when the cable is pulled, the outer part of the sliding block 56 will slide inside the protective shell 27, thereby compressing the spring 592. The deformation of the spring 592 will weaken the pulling force of the cable, thereby reducing the impact of cable pulling and improving the stability of the cable connection of the entire distribution cabinet.
