It can quickly switch over in the event of a fault in any line to ensure uninterrupted power supply. It is small in size, occupies little space, has high reliability, and is easy to maintain. It is widely used in 10kV power distribution networks to improve the continuity and safety of power supply.

[0003] Ring mains emergency power supply is an emergency power supply method that quickly draws temporary power from the reserved interface of the ring mains box when the distribution network fails or is under maintenance. The cable is connected to the special interface of the ring mains box and the emergency power generation vehicle or mobile transformer through fasteners or quick-release plugs. The load transfer and temporary power supply are completed without power interruption. It can quickly isolate the fault and restore power supply. It is suitable for emergency repair, power supply protection and other scenarios, ensures continuous power supply for important loads and improves the emergency response capability of the distribution network.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] First Embodiment Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a ring main unit with an emergency power supply mechanism provided by the present invention; Figure 2 A structural schematic diagram of the shock-absorbing component is provided for this invention; Figure 3 A schematic diagram of the mounting port is provided for this invention; Figure 4 Provided for the present invention Figure 2 An enlarged view of point A shown; Figure 5 Provided for the present invention Figure 3 The enlarged view at point B is shown. The ring main unit with emergency power supply mechanism includes: a shock-absorbing base frame 1; The housing 7 is mounted on the top of the shock-absorbing base frame 1. A power outlet 11 is provided on one side of the housing 7. An installation component 2 is installed on one side of the housing 7 through a sealing component 9. A socket 13 is installed at one end of the installation component 2. A guide hole 28 is provided at one end of the socket 13. A sealing ring 14 is provided at one end of the socket 13. An external threaded ring 12 is installed at one end of the installation component 2. An insulating base 10 is installed on one side of the inner wall of the housing 7. A first power supply frame 16 and a second power supply frame 19 are installed on one side of the insulating base 10. A first power connection structure 17 is installed on the top of the first power supply frame 16, and a second power connection structure 18 is installed on the top of the second power supply frame 19. A first power take-off head 15 is installed at the bottom of the first power supply frame 16, and a second power take-off head 20 is installed at the bottom of the second power supply frame 19. Power take-off wires 21 are installed at the bottom of both the first power take-off head 15 and the second power take-off head 20. A sealing cover 4 is placed on one side of the housing 7 via a placement rack 5; Both the mounting component 2 and the sealing component 9 need to pass through the power outlet 11. The sealing component 9 can ensure the sealing of the connection between the mounting component 2 and the housing 7. The socket 13 has a groove at the position where the sealing ring 14 is installed. The sealing ring 14 wraps around the power outlet, which helps to improve the sealing. The socket 13 and the external threaded ring 12 are located on one side of the housing 7. The insulating base 10 and the power outlet 11 are correspondingly positioned. The first power connection structure 17 and the second power connection structure 18 are respectively connected to the positive and negative poles of the main power supply frame inside the ring network box. The other end of the power supply wire 21 is connected to the positive and negative poles of the socket 13. The sealing cover 4 can be removed to cover the socket 13. The sealing cover 4 and the external threaded ring 12 are threadedly connected to ensure the stability of the connection. The housing 7 is the main body of the ring network box. The equipment installed in the housing 7 is the equipment that needs to be installed inside the ring network box. The socket of the sealing plug 3 has a positioning bolt that mates with the guide hole 28. The sealing cover 4 should be properly placed on one side of the box 7 using the placement rack 5 to avoid loss or damage due to random placement, which would affect the sealing protection of the subsequent socket 13. The sealing ring 14 at one end of the socket 13 should be checked regularly. If it is aged or damaged, it should be replaced in time to ensure that the sealing performance meets the standards. The external thread ring 12 should be kept clean to avoid the accumulation of dust and debris, which would affect the tightness of the sealing cover 4. The connection status of the first power connection structure 17 and the second power connection structure 18 should be checked regularly to prevent loosening and poor contact. The power cord 21 should be protected from excessive pulling and bending to prevent damage to the line and malfunction. At the same time, the dust and debris on the surface of the box 7 and each component should be cleaned regularly to ensure the normal operation of each component. When the main power supply system of the ring network box malfunctions, such as a short circuit, power outage, or poor contact in the main power supply line, and cannot supply power to the equipment normally, emergency power supply is required to ensure the normal operation of the relevant equipment. When a power supply abnormality occurs in part of the ring network box, only the faulty area needs to be repaired, and the remaining areas need to maintain power supply. In this case, emergency power supply can be used to achieve local power supply and avoid overall shutdown. The mechanism is integrated inside and outside the ring main unit 7, without interfering with the original power distribution components such as circuit breakers and busbars inside the unit 7. The first power supply frame 16 and the second power supply frame 19 of the emergency power supply mechanism are precisely connected to the main power supply system inside the ring main unit through the first power connection structure 17 and the second power connection structure 18. It relies on the original power supply foundation of the ring main unit and realizes emergency power supply through an independent circuit without affecting the normal ring main unit power supply function. At the same time, the sealing component 9 of the mechanism works in conjunction with the sealing protection system of the ring main unit 7 to meet the usage requirements of the outdoor compact high voltage power distribution equipment of the ring main unit, realizing the seamless connection between the emergency power supply function and the performance of the ring main unit itself. The shock-absorbing base frame 1 can effectively buffer the impact of external forces such as outdoor construction and vehicle vibration, and prevent the internal power supply frame and power tap from becoming loose due to vibration, thus ensuring the stability of the power connection.

[0022] Please refer to Figure 1 and Figure 2 The shock-absorbing base frame 1 includes a base frame 101, a plurality of shock-absorbing components 102 and a base plate 103, wherein the shock-absorbing components 102 are used to mount the base plate 103 on the top of the base frame 101; The damping component 102 is a spring with a damper, which can improve the damping effect of the housing 7.

[0023] Please refer to Figure 2 and Figure 4 The installation assembly 2 includes a docking frame 201, a fixing bolt 202, a connecting frame 203, and a sealing plate 204. The docking frame 201 is installed on one side of the inner wall of the housing 7 by the fixing bolt 202. The connecting frame 203, in conjunction with the fixing bolt 202, is used to install the sealing plate 204 on one end of the docking frame 201. The sealing disc 204 is located on one side of the housing 7, and the fixing bolt 202 passes through the docking frame 201 and the housing 7 and is threadedly connected to the sealing disc 204. The sealing disc 204 has a threaded hole at one end near the housing 7, and a protrusion at the other end of the sealing disc 204 to ensure the depth of the threaded hole.

[0024] Please refer to Figure 2 and Figure 4 The sealing assembly 9 includes an inner sealing frame 901, a sealing sleeve 902, and a sealing gasket 903. The sealing frame 901 is located between the docking frame 201 and the housing 7, the sealing sleeve 902 is located between the connecting frame 203 and the power outlet 11, and the sealing gasket 903 is located between the sealing disc 204 and the housing 7. The sealing frame 901, sealing sleeve 902 and sealing gasket 903 are a single unit.

[0025] Please refer to Figure 1 The two sides of the housing 7 near the bottom are equipped with filter structures 6, and the two sides of the housing 7 near the top are equipped with heat dissipation structures 8. The heat dissipation structure 8 provides suction to help expel hot air from inside the housing 7, while the filtration structure 6, which includes a frame and a filter screen, can filter dust and allow cool air to enter smoothly.

[0026] The working principle of the ring main unit with emergency power supply mechanism provided by this invention is as follows: A power outlet 11 is provided on one side of the housing 7 near the bottom. The mounting assembly 2 is installed at the power outlet 11 through the sealing assembly 9, so that the socket 13 with the sealing ring 14 and guide hole 28 is fixed on the outside of the housing 7 for quick connection with the sealing plug 3. On the inner wall of the housing 7, corresponding to the position of the power outlet 11, the first power supply frame 16 and the second power supply frame 19 are fixed by the insulating base 10. With the help of the first power connection structure 17 and the second power connection structure 18, the first power supply frame 16 and the second power supply frame 19 are connected to the positive and negative terminals of the ring network box's main power supply, respectively, to build an independent emergency power supply circuit to avoid affecting the normal operation of other power supply equipment. The first power outlet 15 and the second power outlet 20, together with the power supply wire 21, provide stable power to the outer socket 13. When not in use, the dustproof sealing cover 4 and the external threaded ring 12 are tightly fastened to the socket 13. The cavity port precisely fits the edge of the socket 13, forming a double-seal protection with the sealing component 9 and the sealing ring 14 of the socket 13. This effectively isolates external dust, rainwater, moisture and other impurities from entering the insertion cavity and the interior of the housing 7, preventing oxidation and moisture damage to the conductive contacts of the socket 13, and avoiding short circuits and leakage faults. At the same time, it protects the first power supply frame 16, the second power supply frame 19 and the power connection structure from external environmental corrosion. In case of emergency power supply, the sealing cover 4 is removed and the sealed plug 3 is pushed in along the guide hole 28. The asymmetrical anti-misinsertion boss calibrates the phase to ensure that the sealed plug 3 and the socket 13 are phase matched and correctly positioned. After the sealed plug 3 is fully inserted, the sealing ring 14 is deformed under pressure, further filling the gap between the plug and the socket 13, forming a sealed, waterproof and dustproof space. The conductive contacts are precisely connected, and the connection and disconnection can be completed without auxiliary tools, achieving fast and safe power supply.

[0027] Compared with related technologies, the ring main unit with emergency power supply mechanism provided by the present invention has the following beneficial effects: To enhance the safety and efficiency of emergency power supply to the ring main unit, a power outlet 11 is provided on one side of the unit 7 near the bottom. The mounting assembly 2 is installed at the power outlet 11 via the sealing assembly 9, fixing the socket 13 with the sealing ring 14 and guide hole 28 to the outside of the unit 7 for quick connection with the sealing plug 3. On the inner wall of the unit 7, corresponding to the power outlet 11, the first power supply frame 16 and the second power supply frame 19 are fixed using the insulating base 10. Using the first connection structure 17 and the second connection structure 18, the first power supply frame 16 and the second power supply frame 19 are connected to the positive and negative terminals of the ring main unit's main power supply, respectively, to construct an independent emergency power supply circuit, avoiding interference with the normal operation of other power supply equipment. This is achieved through the first power outlet 15 and the second power outlet 2. The plug 0, in conjunction with the power cord 21, provides stable power to the external socket 13. This design eliminates the need for bolt tightening, allowing for plug assembly and disassembly by a single person with one hand, thus shortening traditional wiring time and significantly improving emergency power supply repair efficiency. Multiple seals, combined with the dustproof sealing cover 4, achieve an IP67 protection rating, making it suitable for harsh outdoor environments such as rainy and windy days. This prevents moisture and dust from entering and causing circuit failures. The asymmetrical irregular protrusions on the sealed plug 3 and the guide holes 28 on the socket 13 completely eliminate the problems of incorrect phase and reverse insertion, avoiding the risks of contact burnout, equipment short circuits, and electric shock. The fully enclosed insulating sealing cover 4 isolates live parts, preventing accidental contact. The connectors are tightly interlocked after insertion, making them difficult to loosen, with low conductive contact resistance, ensuring stable power supply without overheating.

[0028] Second Embodiment Please refer to the following: Figures 6-7 , Figure 6 A schematic diagram of the structure of a second embodiment of the ring main unit with an emergency power supply mechanism provided by the present invention; Figure 7 Provided for the present invention Figure 6 The enlarged view at point C shows a ring main unit with an emergency power supply mechanism provided in the first embodiment of this application. The second embodiment of this application proposes another ring main unit with an emergency power supply mechanism. The second embodiment is merely a preferred embodiment of the first embodiment, and its implementation will not affect the independent implementation of the first embodiment.

[0029] Specifically, the difference between the ring main unit with emergency power supply mechanism provided in the second embodiment of this application and the following is as follows: Please refer to... Figure 6 and Figure 7 An adjustment component 24 is installed on one side of the insulating base 10. An insulating frame 25 is installed on the telescopic end of the adjustment component 24. A stabilizing component 22 is installed on the top of the insulating frame 25. A first power-taking head 15 and a second power-taking head 20 are respectively installed at both ends of the insulating frame 25. An arc-extinguishing cover 23 is installed on one side of the insulating frame 25. One side of the stabilizing component 22 is connected to the insulating frame 25. The arc-extinguishing cover 23 covers the power supply frame and the power taking head. When the first power taking head 15, the second power taking head 20 connects with or separates from the first power supply frame 16 and the second power supply frame 19 and generates an electric arc, the arc-extinguishing cover 23 can quickly block the electric arc, suppress the spread and combustion of the electric arc, prevent the electric arc from burning the contacts and damaging the insulation, prevent it from affecting the stability of power taking, and ensure the safety and reliability of the emergency power taking process.

[0030] Please refer to Figure 6 and Figure 7 The adjustment assembly 24 includes an adjustment frame 241, a telescopic component 242, and a support frame 243. The adjustment frame 241 is used to install the telescopic component 242 on one side of the insulating base 10, and the support frame 243 is installed between the telescopic component 242 and the insulating frame 25. The telescopic component 242 can be a mechanical telescopic rod or a telescopic structure that can be used in a powered environment.

[0031] Please refer to Figure 6 and Figure 7 The stabilizing assembly 22 includes a stabilizing frame 221, a plurality of insulating slide rods 222 and an elastic component 223. The stabilizing frame 221 is used to mount the plurality of insulating slide rods 222 on one side of the insulating base 10, and the elastic component 223 is mounted between the slide rods 222 and the top of the stabilizing frame 221. The slide bar 222 slides through the stabilizer 221, and the bottom end of the slide bar 222 is connected to the insulating frame 25.

[0032] Compared with related technologies, the ring main unit with emergency power supply mechanism provided by the present invention has the following beneficial effects: To prevent the socket 13 from being energized when idle, the first power-taking head 15 and the second power-taking head 20 are fixed to the telescopic end of the adjusting component 24 via the insulating frame 25. The telescopic movement of the adjusting component 24 allows the first power-taking head 15 and the second power-taking head 20 to quickly connect and disconnect with the first power supply frame 16 and the second power supply frame 19, thus providing power to the socket 13 as needed. The arc-extinguishing cover 23 installed on one side of the insulating frame 25 prevents the arc generated when the first power-taking head 15 and the second power-taking head 20 connect with the first power supply frame 16 and the second power supply frame 19 from affecting the stability of the power supply. A stabilizing component 22 is installed on the insulating frame 25 and the insulating base 10 to increase the stability of the vertical movement of the insulating frame 25, preventing deviations from affecting the safety of the connection. In the idle state, the adjusting component 24 is in the retracted state, and the first power-taking head 15 and the second power-taking head 20, fixed by the insulating frame 25, remain separated from the first power supply frame 16 and the second power supply frame 19, ensuring that the socket 13 is not energized and eliminating the potential for energization when idle. The stabilizing component 22 is always fixed between the insulating frame 25 and the insulating base 10, maintaining the static stability of the insulating frame 25. When emergency power is needed, the adjusting component 24 is activated and extended, driving the insulating frame 25 to move up and down. The stabilizing component 22 works synchronously to limit the displacement deviation of the insulating frame 25 and ensure its smooth movement. The insulating frame 25 drives the first power taking head 15 and the second power taking head 20 to approach the first power supply frame 16 and the second power supply frame 19 and accurately connect. During the connection process, the arc extinguishing cover 23 on one side of the insulating frame 25 blocks the generated arc to avoid affecting the power supply stability and damaging the equipment. After the connection is completed, the socket 13 obtains stable power supply. After the power is taken out, the adjusting component 24 retracts, driving the power taking head to separate from the power supply frame. The insulating frame 25 resets, and the stabilizing component 22 maintains the reset stability, restoring the idle and non-energized state. This design enables the emergency circuit to be completely disconnected from the main busbar under normal conditions, eliminating the hidden danger of the socket 13 being energized when the main circuit is energized, achieving complete physical insulation isolation, and adopting a fully mechanical structure. In emergency power supply, the first and second power-generating heads 15 and 16 are precisely connected to the first and second power supply frames via the adjustment component 24. During the connection process, the arc-extinguishing cover 23 installed on one side of the insulating frame 25 effectively eliminates the electric arc generated during connection, preventing the arc from affecting the stability of power supply. The stabilizing component 22 ensures the stability of the vertical movement of the insulating frame 25, preventing displacement deviations that could affect the safety of power connection. Subsequently, the guide hole 28 is used to achieve precise connection between the sealed plug 3 and the socket 13 to obtain power. The sealing component 9 provides a waterproof and dustproof seal, eliminating the need for bolt tightening and enabling rapid power connection. When not in use, the adjustment component... When component 24 retracts, it causes the first power-taking head 15 and the second power-taking head to separate from the power supply frame, ensuring that the socket 13 is not energized. At the same time, it is covered by the sealing cover 4, which, together with the sealing component 9, provides all-round protection. When the two work together, through the extension and retraction control of the adjustment component 24, the arc protection of the arc extinguishing cover 23, the precise positioning of the stabilizing component 22, the protection of the sealing component 9, and the convenient docking of the sealing plug 3 and the socket 13, it not only achieves rapid power supply, but also avoids affecting other power supply equipment through an independent power supply circuit. This effectively improves the safety, convenience and stability of emergency power supply and meets the safety and efficiency requirements of emergency power supply.

[0033] Third Embodiment Please refer to the following: Figures 8-9 , Figure 8 A schematic diagram of the third embodiment of the ring main unit with an emergency power supply mechanism provided by the present invention; Figure 9 Provided for the present invention Figure 8 The enlarged view at point D shows a ring main unit with an emergency power supply mechanism provided in the first embodiment of this application. The third embodiment of this application proposes another ring main unit with an emergency power supply mechanism. The third embodiment is merely a preferred embodiment of the first embodiment, and its implementation will not affect the independent implementation of the first embodiment.

[0034] Specifically, the ring main unit with emergency power supply mechanism provided in the third embodiment of this application differs in that, please refer to... Figure 8 and Figure 9 A protective component 26 is installed on one side of the housing 7, and a through-hole 29 is provided on one side of the protective component 26. A handle 27 is installed on one side of the protective component 26. The bottom opening of the protective component 26 and the handle 27 make it easy to open the protective component 26. The protective component 26 can completely cover the socket 13. The through hole 29 on one side makes it easy for the wire of the sealed plug 3 to pass through. This does not affect the emergency power supply operation and can further isolate external impurities. Together with the sealing component 9 and the sealing cover 4, it forms a triple protection, further improving the adaptability to harsh outdoor environments.

[0035] Please refer to Figure 8 and Figure 9The protective component 26 includes a rotating structure 261 and a protective cover 262. The rotating structure 261 is used to rotatably connect the protective cover 262 to one side of the housing 7. The protective cover 262 rotates around the rotating structure 261, which exposes the socket 13.

[0036] Compared with related technologies, the ring main unit with emergency power supply mechanism provided by the present invention has the following beneficial effects: To enhance the sealing between the sealed plug 3 and socket 13 during emergency power extraction, thereby improving the safety and stability of the process, a protective component 26 is installed on one side of the housing 7, corresponding to the mounting component 2. This protective component 26 is equipped with a through-hole 29 and a handle 27. Its structural design is tailored to the actual needs of emergency power extraction, providing comprehensive protection for both the sealed plug 3 and socket 13 while ensuring smooth power extraction. During use, the protective component 26 can be easily opened and closed via the handle 27, completely covering the mating area between the sealed plug 3 and socket 13 to form a closed protective space. This effectively isolates external dust, rainwater, moisture, and other impurities, preventing these impurities from entering the mating gaps and affecting the contact effect. The through-hole 29 on the protective component 26 precisely matches the wiring size of the sealed plug 3, allowing the connecting wires of the sealed plug 3 to pass through smoothly. This design does not affect the normal connection between the plug and the socket, nor does it cause the seal to fail due to wire pulling. This design not only significantly enhances the sealing performance when the sealed plug 3 and the socket 13 are connected, but also further strengthens the protection of the connection points. It effectively reduces the corrosion and damage caused by external factors such as harsh outdoor environments, dust, and moisture to the connection points, and avoids problems such as poor contact and short circuits that may affect emergency power supply. This ensures the stability and safety of the emergency power supply process, while also taking into account ease of operation and not affecting power supply efficiency. It works effectively with the overall emergency power supply system to further improve the overall protection performance and operational reliability of the equipment.

Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
