Description

Technical Field

[0001] This invention relates to the field of high-voltage complete equipment technology, and in particular to a lifting high-voltage electrical bay complete equipment. Background Technology

[0002] With the rapid growth of electricity consumption across society, higher demands are being placed on the power supply capacity and reliability of the power system. This has prompted the power industry to continuously increase its investment in power grid construction, thereby driving the growth in demand for power equipment such as high-voltage electrical bay switchgear. The rapid development of distributed energy sources, such as solar and wind power, has made the structure of the power system more complex. These distributed energy sources are usually connected to the power grid in a small-scale and decentralized manner, requiring high-voltage electrical bay switchgear to effectively connect, control, and protect these distributed power sources to ensure the safe and stable operation of the power grid.

[0003] The prior art CN116316190A discloses a high-voltage complete set of equipment that is easy to maintain, including a sliding plate, a lifting mechanism, and a locking mechanism. Each of the four mounting plates has a sliding plate for mounting the high-voltage equipment slidably mounted on its upper part. All four mounting plates are located inside the outer casing. A lifting mechanism is installed on the support frame to drive the outer casing upwards and open it. A locking mechanism is installed on the outer casing to fix and limit the outer casing. A motor is used as the driving force to drive the second winding wheel to rotate forward, thereby pulling a rope to move the sliding frame upwards. The upward movement of the sliding frame causes the outer casing to move upwards and open, exposing all the high-voltage equipment, facilitating maintenance by personnel and improving maintenance efficiency.

[0004] However, the above-mentioned equipment also has the following disadvantages: the cabinet structure is large in size, occupies a lot of space, and is relatively complicated to operate and maintain; for electrical equipment installed at high places, the installation, troubleshooting and maintenance are difficult.

[0005] Therefore, there is an urgent need to provide a lifting-type high-voltage electrical compartment complete set of equipment, which, compared with the existing technology, improves space utilization, facilitates maintenance of electrical equipment at heights, and enhances safety. Summary of the Invention

[0006] This invention addresses the technical problems existing in the prior art and provides a lifting-type high-voltage electrical bay complete set of equipment.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A lifting-type high-voltage electrical bay assembly includes a lifting platform, multiple piles, a transmission assembly, and multiple electrical devices. The lifting platforms are positioned between adjacent piles. Each lifting platform has a transmission assembly on both sides, which drives the lifting platform to move axially along the pile. The electrical devices include disconnect switches. Each lifting platform has two disconnect switches. Each disconnect switch includes a first post insulator and a second post insulator. The first post insulator is located on the upper part of the pile, and the second post insulator is located on the upper part of the lifting platform. When the lifting platform moves to its uppermost position, the first post insulator and the second post insulator are connected; when the lifting platform moves to its lowermost position, the first post insulator and the second post insulator are disconnected.

[0009] Furthermore, a left switch is provided on the side wall of the first post insulator, and a right switch is provided on the side wall of the second post insulator. The left switch and the right switch are connected by a meshing assembly.

[0010] Furthermore, the engagement assembly includes a first groove, a first protrusion, a second groove, and a second protrusion. The first groove and the first protrusion are disposed on the left knife end face, with the first groove located below the first protrusion. The second groove and the second protrusion are disposed on the right knife end face, with the second groove located above the second protrusion. The first protrusion extends into the second groove, and the second protrusion extends into the first groove. The first protrusion and the second protrusion are engaged.

[0011] Furthermore, a first permanent magnet is disposed on the end face of the first protrusion away from the first groove, and a second permanent magnet is disposed on the end face of the second protrusion away from the second groove, wherein the magnetic properties of the opposite end faces of the first permanent magnet and the second permanent magnet are opposite.

[0012] Furthermore, a spring is connected between the second post insulator and the right switch.

[0013] Furthermore, the transmission assembly includes a transmission gear, a rack, a gearbox, and a motor. The gearbox is located on the side of the lifting platform, and both the transmission gear and the motor are located inside the gearbox. The rack is located on the side wall of the pile, and the transmission gear meshes with the rack.

[0014] Furthermore, the rack is provided with limiting blocks at both the upper and lower ends.

[0015] Furthermore, the electrical equipment also includes a circuit breaker, a current display, and a current transformer, all of which are mounted on the lifting platform.

[0016] Furthermore, the first post insulator and the second post insulator are both equipped with equipment clamps at their upper ends. The circuit breaker and the current transformer are also equipped with equipment clamps at both ends. The disconnecting switch, the circuit breaker, the current transformer and the disconnecting switch on the other side of the lifting platform are electrically connected by a stranded wire, which is connected to the equipment clamp.

[0017] Furthermore, a controller is provided on the side wall of the pile column, and the controller is electrically connected to all the motors and the current display.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) When maintenance is required, the maintenance personnel can check the current display on the controller to see if the lifting platform is energized. By controlling the motor to rotate, the lifting platform can be lowered, ensuring that the isolating switch is disconnected and that maintenance work can be carried out without residual current or breakdown accident. This greatly improves the safety of maintenance work and reduces the difficulty of maintenance work. There is no need to carry out maintenance at height. Lowering the lifting platform to a suitable maintenance height can ensure both safety and convenience. At the same time, when the equipment is working normally, the electrical equipment is integrated on the lifting platform, which occupies a small volume and the space under the lifting platform is also highly utilized.

[0020] (2) The transmission component of this invention uses a motor-controlled transmission gear and rack system, resulting in a more compact structure that can be integrated internally or peripherally. It does not occupy excessive space when not in use, optimizing space layout and improving utilization, making it particularly suitable for small substations with limited space. Regarding equipment maintenance convenience, traditional methods require climbing or erecting scaffolding to maintain equipment at heights, which is time-consuming, labor-intensive, and risky. This invention can quickly and smoothly transport operators and tools to a designated height, facilitating the maintenance of high-altitude equipment such as high-voltage disconnect switches. In terms of safety, traditional climbing methods pose high risks in high-voltage environments, such as exhaustion during climbing, tool drops, and difficulties in evacuation in emergencies. This invention improves safety protection measures, such as emergency braking and fall protection devices, ensuring the safe evacuation of operators in emergencies. Regarding automation, traditional height adjustment relies on manual labor, while this invention enables automated control, allowing for better integration with substation automation systems. It can automatically adjust equipment height according to preset programs and perform regular inspections, offering significant advantages for unmanned substation inspections.

[0021] (3) Regarding the ease of installation and maintenance, traditional devices require multiple debugging sessions, while this invention, with its lifting mechanism, can complete most of the assembly and debugging in the factory, resulting in faster on-site installation. During maintenance, traditional devices have scattered fault points, while this invention integrates them into the lifting platform, facilitating centralized maintenance and reducing costs. In terms of space utilization and environmental adaptability, traditional devices occupy a large area in limited spaces, while this invention saves more space. Furthermore, the integrated equipment can better resist dust, moisture, small animals, etc., and can avoid long-term exposure to harsh environments through lifting, extending the equipment's lifespan. In terms of operation and safety, traditional operations are complex and prone to errors, while this invention allows for unified operation, making it more accurate and reliable. At the same time, this invention is also equipped with guardrails, interlocking devices, etc., making the equipment connection tighter and reducing safety hazards. In terms of equipment collaboration and functional expansion, traditional devices are prone to signal interference and transmission failures, while this invention has tight and stable connections and reliable transmission. Moreover, if functional expansion is required, this invention can easily add and modify equipment on the lifting platform, while traditional devices require large-scale modifications and rewiring.

[0022] (4) This invention uses an ungrounded disconnector, which has the following advantages: First, it improves contact reliability. Traditional methods are prone to poor contact due to vibration and thermal expansion and contraction, while the meshing assembly provides stable contact pressure through mechanical structure, reducing contact resistance, lowering the risk of contact overheating, and ensuring stable operation. Second, it enhances short-circuit resistance. Traditional contacts are prone to bouncing and separating under short-circuit current impact, generating arcs and damaging equipment. The meshing assembly can withstand short-circuit electromagnetic force, suppressing contact abnormalities, reducing arcs, and enhancing the disconnector's ability to cope with short circuits. Third, it extends service life. Traditional contacts have many problems and require frequent replacement, resulting in high costs. With the meshing assembly, contact wear and burn-off are improved, reducing maintenance and replacement frequency and lowering costs. Fourth, it improves operational convenience. Traditional operation requires large force and is difficult to judge the opening and closing status. The meshing device is easy to operate, has clear feedback and indicator marks, and is easy to operate accurately. Meanwhile, the addition of a spring enhances stability. A buffer spring at the contact root ensures a tighter fit between the first and second protrusions when operating at the highest point, effectively resolving the shaking and vibration issues that may occur during operation due to insufficient contact. Reducing shaking and vibration is crucial for high-voltage electrical equipment, as these adverse reactions can accelerate contact wear, shorten equipment lifespan, and even cause safety hazards such as electric arcs, affecting normal equipment operation and the stability of power transmission. Furthermore, it improves contact reliability. A tight fit helps ensure good electrical contact, which is critical for normal current conduction in high-voltage electrical environments. Poor contact can lead to localized overheating, damaging equipment and potentially causing serious accidents such as fires. The addition of the spring mechanically guarantees contact reliability and reduces the likelihood of malfunctions due to contact problems. The addition of a first and second permanent magnet enhances the safety of the fit. By adding two permanent magnets to the upper and lower sides of the meshing assembly, the stability of the fit is further strengthened. The magnetic force generated by the permanent magnets provides additional attraction to the fit under normal operating conditions, ensuring a tight connection under various conditions (such as minor external vibrations or electromagnetic interference), preventing accidental separation. This also ensures operational safety. For high-voltage electrical compartment systems, any unexpected situation could lead to serious safety accidents, such as electric shock, equipment damage, and large-scale power outages. The addition of permanent magnets improves the overall safety of the device, reducing the risk of loosening or accidental detachment of the fit, and providing a more reliable guarantee for the safe and stable operation of the equipment.

[0030] like Figure 1 As shown, the present invention provides a lifting high-voltage electrical compartment assembly, comprising a lifting platform 1, multiple piles 8, a transmission assembly, and multiple electrical devices. The piles 8 are made of concrete and are fixedly installed on the ground. A lifting platform 1 is provided between two adjacent piles 8. The piles 8 on both sides of the lifting platform 1 are of the same size. Each lifting platform 1 has a transmission assembly at both ends. The transmission assembly is partially installed on the side wall of the pile 8 and the remaining part is installed on the lifting platform 1. The transmission assemblies on both sides of the lifting platform 1 jointly drive the lifting platform 1 to move up and down. The electrical devices include disconnect switches 11, and two disconnect switches 11 are provided for each lifting platform 1.

[0031] like Figure 1 , Figure 2 , Figure 4As shown, two disconnect switches 11 corresponding to the lifting platform 1 are symmetrically arranged along the vertical line of the upper wall of the lifting platform 1. Each disconnect switch 11 includes a first post insulator 111, a second post insulator 112, a left switch 113, a right switch 114, and an engagement assembly. The first post insulator 111 and the second post insulator 112 are respectively mounted on the pile 8 and the lifting platform 1. The lower end of the first post insulator 111 is fixedly connected to the upper wall of the pile 8, and the lower end of the second post insulator 112 is fixed to one end of the upper wall of the lifting platform 1. The left knife switch 113 is fixedly connected to the upper side wall of the first post insulator 111, and the right knife switch 114 is fixedly connected to the upper side wall of the second post insulator 112. The left knife switch 113 and the right knife switch 114 of the same disconnecting switch 11 are arranged opposite to each other. The left knife switch 113 and the right knife switch 114 of the same disconnecting switch 11 are connected and disconnected through a meshing assembly. A spring 115 is provided between the second post insulator 112 and the right knife switch 114, which can reduce vibration and shaking, extend the service life of the equipment, and ensure good electrical contact.

[0032] The engagement assembly includes a first groove 1131, a first protrusion 1132, a second groove 1141, and a second protrusion 1142. The first protrusion 1132 and the first groove 1131 are disposed at the end of the left switch 113 near the right switch 114. The first groove 1131 is disposed below the first protrusion 1132. The second groove 1141 and the second protrusion 1142 are disposed at the end of the right switch 114 near the left switch 113. The second groove 1141 is located above the second protrusion 1142. When the left switch 113 and the right switch 114 are connected, the first protrusion 1132 is located inside the second groove 1141, and the second protrusion 1142 is located inside the first groove 1131. The first protrusion 1132 and the second protrusion 1142 are engaged, thereby enabling the left switch 113 and the right switch 114 to be connected.

[0033] A first permanent magnet 116 is provided on the end face of the first protrusion 1132 away from the first groove 1131, and a second permanent magnet 117 is provided on the end face of the second protrusion 1142 away from the second groove 1141. The end faces of the first permanent magnet 116 and the second permanent magnet 117 are magnetic poles with opposite magnetic properties. Therefore, when the left switch 113 and the right switch 114 are connected, the first permanent magnet 116 and the second permanent magnet 117 attract each other, further ensuring the stable connection between the left switch 113 and the right switch 114, enhancing the tightness of the fit, improving the reliability of the connection, ensuring the normal conduction of electrical equipment, and preventing accidental separation.

[0034] like Figure 1 , Figure 3As shown, the transmission assembly includes a transmission gear 3, a rack 7, a gearbox 2, and a motor 4. The gearbox 2 is located on the end face of the lifting platform 1. The motor 4 and the transmission gear 3 are installed inside the gearbox 2. The motor 4 drives the transmission gear 3 to rotate. The gear is installed on the side wall of the column 8 near the lifting platform 1. The transmission gear 3 meshes with the rack 7 for transmission. The gearbox 2 has a bearing 5 inside, and a bearing cover is installed outside the bearing 5. The bearing cover is connected to the gearbox 2 by bolts 6. The bearing 5 is fixed to the gearbox 2 by the bearing cover. The bearing 5 is a sliding bearing. The gearbox 2 is made of stainless steel, and the transmission gear 3 is made of carbon steel. Limiting blocks 10 are fixedly connected to both the upper and lower ends of the rack 7 to prevent the transmission gear 3 from moving off the rack 7. The motors 4 installed in the transmission assemblies on both sides of the lifting platform 1 rotate simultaneously, thereby driving the corresponding transmission gears 3 to rotate, so that the lifting platform 1 can move up and down.

[0035] The diameter of the pile 8 is at least 350mm, and the distance between two adjacent piles 8 is at least 4700mm; the thickness of the lifting platform 1 is at least 140mm, and the lifting platform 1 is made of No. 16 channel steel; before use, the lifting platform 1 needs to be tested for its load-bearing capacity, and only after it meets the design requirements can other components be loaded; the limit block 10 is made of No. 5 angle steel; the thickness of the steel plate is 10mm.

[0036] The electrical equipment also includes a circuit breaker 12, a current indicator 13, and a current transformer 14. All three are mounted on the lifting platform 1. The circuit breaker 12, current indicator 13, current transformer 14, and the second post insulator 112 are fixedly connected to the lifting platform 1 via steel plates. The steel plates provide shock absorption and allow for adjustment of the gaps and heights between the electrical equipment. Equipment clamps 15 are provided on both the first post insulator 111 and the second post insulator 112. Equipment clamps 15 are also provided at both ends of the circuit breaker 12 and the current transformer 14. Stranded wires 16 are sequentially connected to the disconnecting switch 11, circuit breaker 12, and current transformer 14 located on the left side of the lifting platform 1, and to the disconnecting switch 11 located on the right side of the lifting platform 1. The stranded wires 16 are connected to the corresponding equipment clamps 15. When the disconnecting switch 11 is closed, electrical transmission occurs through the stranded wires 16; when the disconnecting switch 11 is open, electrical transmission stops.

[0037] Each transmission component has a motor 4 and a current display 13, which are typically connected to a controller 9. The controller 9 is located on the side wall of the pile 8, in the lower middle part of the side wall of the pile 8. The current display 13 is used to conveniently detect whether the lifting platform 1 is energized. When all disconnect switches 11 are connected, the current flows through the disconnect switch 11 on the left to the circuit breaker 12. The circuit breaker 12 is an SF6 circuit breaker. SF6 gas has excellent insulation and arc-extinguishing properties in the equipment. When an electric arc is generated, SF6 gas can quickly absorb the energy of the arc. Due to its large molecular weight and large heat capacity, it can efficiently cool and extinguish the arc during the arc extinguishing process. After passing through the circuit breaker 12, the current enters the current transformer 14, and finally flows out through the disconnect switch 11 on the right, completing a complete current path.

[0038] The current transformer 14 has the following advantages: it can measure current, converting a large primary current into a small secondary current (such as 5A or 1A) according to a certain ratio, which is convenient for measurement. The actual primary current can then be calculated through the transformation ratio. It has a protective function, providing current signals to protection devices. When a circuit fault occurs, it helps the relay protection device to make a judgment and triggers the circuit breaker 12 to operate, thereby protecting the entire power system. It also plays an isolation role, achieving electrical isolation between the primary and secondary sides, ensuring the safety of secondary equipment and operators, while reducing electromagnetic interference and improving system reliability.

[0039] When maintenance is required, the maintenance personnel can check the reading on the current display 13 on the controller 9 to determine whether the lifting platform 1 is energized. By controlling the rotation of the motor 4, the lifting platform 1 is lowered, ensuring that the isolating switch 11 is disconnected. This also ensures that maintenance work can be carried out without residual current or breakdown accidents, which greatly improves the safety of maintenance work and reduces its difficulty. Maintenance work does not require working at height. Lowering the lifting platform 1 to a suitable maintenance height ensures both safety and convenience. At the same time, when the equipment is working normally, the electrical equipment is integrated on the lifting platform 1, occupying a small volume, and the space under the lifting platform 1 is also utilized more efficiently.

[0040] The transmission component of this invention uses a motor 4 to control the transmission gear 3 and rack 7, resulting in a more compact structure that can be integrated internally or peripherally. When not in use, it doesn't occupy much space, optimizing spatial layout and improving utilization, making it particularly suitable for small substations with limited space. Regarding equipment maintenance convenience, traditional methods require climbing or erecting scaffolding to maintain equipment at heights, which is time-consuming, labor-intensive, and risky. This invention can quickly and smoothly transport operators and tools to designated heights, facilitating maintenance of equipment at heights such as high-voltage disconnect switches 11. In terms of safety, traditional climbing methods pose high risks in high-voltage environments, such as exhaustion during climbing, tool drops, and difficulties in evacuation in emergencies. This invention improves safety protection measures, such as emergency braking and fall protection devices, ensuring the safe evacuation of operators in emergencies. Regarding automation, traditional height adjustment relies on manual operation, while this invention enables automated control, allowing for better integration with substation automation systems. It can automatically adjust equipment height according to preset programs and perform regular inspections, offering significant advantages for unattended substation inspections.

[0041] In terms of ease of installation and maintenance, traditional devices require multiple debugging sessions, while this lifting device can complete most of the assembly and debugging in the factory, allowing for quick on-site installation. During maintenance, traditional devices have scattered fault points, while this invention integrates them into the lifting platform 1, facilitating centralized maintenance and reducing costs. Regarding space utilization and environmental adaptability, in spaces with limited space, traditional devices occupy a large area, while this invention saves more space. Furthermore, the integrated equipment is better resistant to dust, moisture, and small animals, and the lifting mechanism prevents long-term exposure to harsh environments, extending the equipment's lifespan. In terms of operation and safety, traditional operations are complex and prone to errors, while this invention allows for unified operation, making it more accurate and reliable. Additionally, this invention includes protective railings and interlocking devices, ensuring tighter equipment connections and reducing safety hazards. Regarding equipment collaboration and functional expansion, traditional devices are prone to signal interference and transmission failures, while this invention features tight, stable connections and reliable transmission. Moreover, if functional expansion is required, this invention allows for easy addition and modification of equipment on the lifting platform 1, whereas traditional devices require large-scale modifications and rewiring.

[0042] This invention employs an ungrounded disconnector 11, which offers the following advantages: First, it improves contact reliability. Traditional methods are prone to poor contact due to vibration and thermal expansion and contraction, while the engagement assembly provides stable contact pressure through a mechanical structure, reducing contact resistance, lowering the risk of contact overheating, and ensuring stable operation. Second, it enhances short-circuit resistance. Traditional contacts are prone to bouncing and separating under short-circuit current impacts, generating arcs and damaging equipment. The engagement assembly can withstand short-circuit electromagnetic forces, suppressing contact abnormalities, reducing arcing, and enhancing the short-circuit resistance of the disconnector 11. Third, it extends service life. Traditional contacts often have problems requiring frequent replacement, resulting in high costs. With the engagement assembly, contact wear and burn-off are improved, reducing maintenance and replacement frequency and lowering costs. Fourth, it improves operational convenience. Traditional operations require significant force and are difficult to determine the opening and closing status. The engagement device is labor-saving, provides clear feedback and indicators, and facilitates accurate operation. Meanwhile, the addition of spring 115 enhances stability. The buffer spring 115, located at the root of the contact, ensures a tighter fit between the first protrusion 1132 and the second protrusion 1142 when operating at the highest point. This effectively solves the problem of shaking and vibration that may occur during operation due to insufficient fit. Reducing shaking and vibration is crucial for high-voltage electrical equipment, as these adverse reactions can lead to accelerated contact wear, shorten equipment lifespan, and even cause safety hazards such as electric arcs, affecting normal operation and the stability of power transmission.

The addition of permanent magnets improves the overall safety of the device, reducing the risk of loosening or accidental detachment of the fit, and providing a more reliable guarantee for the safe and stable operation of the equipment.
