Description

Technical Field

[0001] This invention relates to the field of intelligent ring network box technology, specifically an intelligent ring network box that supports remote control and dispatch control and its application in smart grid power transmission. Background Technology

[0002] Ring main units are key node equipment in power distribution network systems. They are responsible for ring main power supply and load cut-off. The box usually contains a fully sealed stainless steel gas box, which houses high-voltage live components such as load switches, circuit breakers, and grounding switches. It is also filled with SF6 or environmentally friendly arc-extinguishing gas at a certain pressure to ensure electrical insulation strength and arc-extinguishing capability during fault interruption.

[0003] When a short circuit fault, insulation breakdown, or arc extinguishing failure occurs, the internal arcing temperature can reach over 10,000°C. The arc-extinguishing gas expands rapidly within milliseconds, causing the gas box pressure to surge rapidly. Therefore, the gas box must have the ability to reliably release pressure when the pressure rises abnormally.

[0004] In existing technologies, the pressure relief protection of ring main unit gas boxes mainly adopts explosion-proof diaphragms. This involves setting a pressure relief port at the bottom of the gas box and covering it with an explosion-proof diaphragm. When the internal pressure reaches a preset burst threshold, the diaphragm ruptures instantaneously, forming a pressure relief channel and directly venting the high-pressure gas to the outside. However, the explosion-proof diaphragm is a one-time action element; after activation, the machine must be shut down and the diaphragm replaced, increasing maintenance workload and costs. Furthermore, the equipment is taken out of service during replacement, affecting power supply reliability.

[0005] To address the issue of non-reusable explosion-proof diaphragms, some solutions employ resettable pressure relief valves to depressurize the gas chamber. Pressure is released by the valve core moving due to air pressure overcoming spring force; once the pressure drops, the spring pushes the valve core back to its original position, restoring the seal. However, existing resettable pressure relief valves typically only have a single pressure relief path. In the event of a severe arcing fault causing a rapid and sudden increase in gas chamber pressure, the discharge capacity of this single path may be insufficient to completely expel the high-pressure gas within a short time, posing a risk of damage to the gas chamber due to excessive pressure. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent ring network box that supports remote control and dispatching, and its application in smart grid power transmission, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A smart ring main unit supporting remote control and dispatching includes:

[0009] The enclosure includes a housing and a plurality of pressure relief holes formed at equal intervals at the bottom of the housing. The bottom of the housing is connected to a tapered pipe and a discharge pipe that are in communication with the pressure relief holes.

[0010] Also includes:

[0011] A gradual conduction mechanism is installed inside the box and connected to the conical tube. A sealing tube that cooperates with the conical tube is connected to the gradual conduction mechanism. The gradual conduction mechanism can operate when the air pressure inside the box changes, and adjust the conduction state of the conical tube through the sealing tube.

[0012] A pressure relief mechanism is provided on the gradual conduction mechanism. The pressure relief mechanism can adjust the conduction state of the sealing tube when the gradual conduction mechanism moves.

[0013] As a further aspect of the present invention: the conical tube forms two chambers, namely a sealed chamber and a conical chamber.

[0014] As a further aspect of the present invention: when the sealing tube passes through the sealing chamber, it cooperates with the conical chamber to form a pressure relief channel.

[0015] As a further embodiment of the present invention: the gradual conduction mechanism includes guide columns connected to the housing and symmetrically distributed, a support plate sliding axially on the guide columns, a support rod mounted on the support plate, and the support rod connected to the sealing tube.

[0016] As a further embodiment of the present invention: the gradual conduction mechanism further includes a first fixed ring and a second fixed ring connected to the guide post, the support plate abutting against the first fixed ring, and a first spring sleeved on the guide post, the two ends of the first spring abutting against the second fixed ring and the support plate respectively.

[0017] As a further embodiment of the present invention: the triggering pressure relief mechanism includes a connecting plate slidably mounted on the guide column and slidably connected to the support rod, a limit ring is installed on the support rod, and a second spring is sleeved on the support rod, with the two ends of the second spring abutting against the limit ring and the connecting plate respectively.

[0018] As a further embodiment of the present invention: the trigger pressure relief mechanism further includes a first through hole formed at the end of the sealing tube, a sliding sleeve connected to the connecting plate is slidably installed on the support rod, a sealing disc is connected to the end of the sliding sleeve, the sealing disc is sealed and fitted with the sealing tube, and a second through hole is formed on the sealing disc that communicates and cooperates with the first through hole.

[0019] As a further embodiment of the present invention: push rods are symmetrically distributed on the support plate, and the ends of the push rods are connected to sealing plugs that are slidably and sealingly connected to the discharge pipe.

[0020] Application of a smart ring network box supporting remote dispatch control as described in any of the above in smart grid power transmission.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This invention, by setting a gradual conduction mechanism, overcomes the elastic force of the first spring when the air pressure in the air box rises, pushing the sealing tube from the sealing chamber to the conical chamber to form a pressure relief channel. After the pressure falls back, the first spring pushes the sealing tube to reset and re-seal the air passage. Compared with the traditional explosion-proof diaphragm, which requires shutdown and replacement after a single action, this invention can achieve multiple repeated actions without replacing vulnerable parts, reducing maintenance workload and costs, and reducing the time the equipment is out of operation due to pressure relief.

[0023] When a severe fault such as a short circuit or insulation breakdown occurs inside the ring main unit, causing the pressure inside the gas box to surge rapidly and exceed the safety threshold, the high-pressure gas pushes the sealing tube to move significantly and rapidly. The sealing disc separates from the sealing tube, making the first and second through holes connected. The high-pressure gas then forms a second pressure relief path through the inside of the sealing tube. Simultaneously, the clearance between the outer wall of the sealing tube and the conical chamber increases synchronously with the increase in the displacement of the sealing tube, forming a first pressure relief path. The support plate drives the push rod to push the sealing plug out of the discharge pipe, forming a third pressure relief path. The simultaneous opening of the three pressure relief paths effectively increases the pressure relief and discharge area, solving the problem of insufficient discharge capacity of a single pressure relief path under extreme arcing conditions. It can quickly discharge the high-pressure gas inside the gas box in a very short time, preventing the gas box from being damaged due to excessive pressure. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0038] Please see Figures 1-11 In this embodiment of the invention, an intelligent ring network box supporting remote control and scheduling includes:

[0039] The box body 1, and a plurality of pressure relief holes 101 formed at the bottom of the box body 1 and distributed at equal intervals, wherein the bottom of the box body 1 is connected to a tapered pipe 2 and a discharge pipe 3 that are in communication with the pressure relief holes 101;

[0040] Also includes:

[0041] A gradual conduction mechanism is installed inside the housing 1 and connected to the conical tube 2. A sealing tube 8 that cooperates with the conical tube 2 is connected to the gradual conduction mechanism. The gradual conduction mechanism can operate when the air pressure inside the housing 1 changes, and adjust the conduction state of the conical tube 2 through the sealing tube 8.

[0042] A trigger pressure relief mechanism is provided on the gradual conduction mechanism. The trigger pressure relief mechanism can adjust the conduction state of the sealing tube 8 when the gradual conduction mechanism moves.

[0043] Specifically, housing 1 is typically composed of multiple compartments, one of which is a gas chamber containing high-voltage live components, including composite switches, circuit breakers, and grounding switches. This gas chamber is sealed to ensure that the components are unaffected by the external environment. It is filled with arc-quenching gas. When the load switch or circuit breaker performs normal opening and closing operations, or when the external temperature fluctuates, the gas pressure inside the chamber will fluctuate, but the fluctuation range is small. Under these conditions, no pressure relief is required to ensure that the arc-quenching gas does not leak. However, if the components inside the chamber overheat abnormally, such as due to poor contact leading to temperature rise, the heat will be continuously transferred to the arc-quenching gas, causing the pressure to rise slowly and continuously. If not released, the accumulated pressure can easily damage the components. Therefore, the gas pressure... When the pressure reaches a preset threshold, the tapered tube 2 is slightly opened by the clearance action of the sealing tube 8 to continuously and slightly relieve pressure and ensure that the pressure does not accumulate. If a short circuit, arc discharge, or insulation breakdown occurs inside the ring main unit, the temperature will rise sharply. The arc-extinguishing gas will expand and decompose rapidly due to the heat, causing the pressure inside the gas box to rise rapidly and exceed the safety threshold. At this time, the tapered tube 2 will move quickly under the action of air pressure, which will rapidly increase the conductivity of the tapered tube 2. At the same time, the tapered tube 8 will also trigger the pressure relief mechanism to move, so that the sealing tube 8 itself will also be opened, forming a rapid pressure relief outlet, thereby quickly expelling the gas in the gas box to ensure effective protection of the ring main unit.

[0044] Please see Figure 7 The conical tube 2 forms two chambers, namely a sealed chamber and a conical chamber. When the sealed tube 8 passes through the sealed chamber, it cooperates with the conical chamber to form a pressure relief channel.

[0045] Please see Figures 3-10The gradual conduction mechanism includes guide posts 4 connected within the housing 1 and symmetrically distributed. A support plate 5 slides axially on the guide posts 4. A support rod 6 is installed on the support plate 5 and connected to the sealing tube 8. The gradual conduction mechanism also includes a first fixing ring 401 and a second fixing ring 402 connected to the guide posts 4. The support plate 5 abuts against the first fixing ring 401. A first spring 9 is sleeved on the guide posts 4, and the two ends of the first spring 9 abut against the second fixing ring 402 and the support plate 5, respectively.

[0046] In detail, the air box inside the housing 1 is in an inflated state during normal use, and a slight positive pressure is formed inside the air box. Under the action of the slight positive pressure, it can ensure that external moisture, dust, salt spray and other external factors cannot seep in through tiny gaps, and also ensure electrical insulation performance.

[0047] Please see Figure 7 In the initial state, the support plate 5 is located at the end of its stroke away from the conical tube 2 and is in contact with the first fixing ring 401. At this time, the distance between the support plate 5 and the second fixing ring 402 is the largest. The extension of the first spring 9 in its natural state is greater than the maximum distance between the support plate 5 and the second fixing ring 402. Therefore, the first spring 9 is in a pre-compressed state and always provides the support plate 5 with a thrust in the direction away from the conical tube 2. Under the action of the support plate 5, the sealing tube 8 is controlled by the support rod 6 to be located in the sealing chamber of the conical tube 2. The sealing tube 8 forms a seal on the conical tube 2, ensuring that the air box is in a closed state during normal use.

[0048] When the load switch or circuit breaker performs normal opening and closing operations, or when the external temperature fluctuates, the gas pressure in the gas box will fluctuate slightly. Under these conditions, the slight fluctuation in gas pressure cannot overcome the elastic force of the first spring 9, thereby ensuring that the position of the sealing tube 8 in the tapered tube 2 will not change, the gas box is in a completely sealed state, and there is no leakage of arc extinguishing gas.

[0049] Please see Figure 8 When the components inside the gas box experience a continuous temperature rise due to an abnormal malfunction, the gas pressure will slowly rise and gradually overcome the elastic force of the first spring 9, pushing the sealing tube 8 to move. This, in turn, drives the support plate 5 to slide along the guide column 4 towards the conical tube 2 via the support rod 6. When the gas pressure rises to a preset threshold, the sealing tube 8 completely moves out of the sealing chamber and into the conical chamber. A gap is formed between the outer wall of the sealing tube 8 and the inner wall of the conical chamber. This gap is the pressure relief channel. The high-pressure gas inside the gas box can be discharged along the conical tube 2 through this pressure relief channel, achieving slow pressure relief and preventing the continuous accumulation of gas pressure from threatening the safety of the ring network box structure.

[0050] The bottom of the housing 1 is also provided with a collection chamber, which is connected to the conical tube 2 and the discharge tube 3. It can collect the arc-extinguishing gas discharged by the conical tube 2 and the discharge tube 3, and after filtration and other treatments, it is refilled into the return gas box.

[0051] During the depressurization process, the pressure inside the air box gradually decreases. When the pressure drops back to a safe range, the elastic force of the first spring 9 pushes the support plate 5 to reset, causing the sealing pipe 8 to retract into the sealing chamber, completing the sealing again and maintaining the normal working pressure of the air box.

[0052] Please see Figure 9 When a short circuit or insulation breakdown occurs inside the ring main unit, the temperature inside the gas box rises sharply and instantaneously. The arc-extinguishing gas expands rapidly due to the heat, and the gas pressure will soar to a level far exceeding the preset threshold and the safety threshold in a short time. At this time, the gas pressure will quickly push the sealing pipe 8 to move significantly, and through the support rod 6, it will drive the support plate 5 to move significantly along the guide column 4. During the movement, the support plate 5 will drive the pressure relief mechanism to move synchronously. The pressure relief mechanism will cause the sealing pipe 8 to conduct itself, and the high-pressure gas in the gas box can be directly discharged through the sealing pipe 8. Together with the pressure relief channel formed by the conical chamber and the outer wall of the sealing pipe 8, a high-flow-rate rapid pressure relief channel is formed to quickly discharge the high-pressure gas in the gas box and avoid excessive pressure from damaging the structure of the box 1.

[0053] A displacement sensor is also installed on the guide column 4 to detect the displacement of the support plate 5. The displacement signal is converted into a digital signal and sent to the station terminal. The station terminal calculates the real-time pressure inside the gas box based on the displacement and incorporates the pressure value into the arc extinguishing capability pre-verification logic. That is, when the displacement exceeds the threshold, the allowable interruption current level is dynamically reduced or the remote control short circuit current is prohibited.

[0054] Please see Figures 3-11 The trigger pressure relief mechanism includes a connecting plate 10 slidably mounted on the guide post 4 and slidably connected to the support rod 6. A limit ring 7 is installed on the support rod 6, and a second spring 11 is sleeved on the support rod 6. The two ends of the second spring 11 abut against the limit ring 7 and the connecting plate 10, respectively. The trigger pressure relief mechanism also includes a first through hole 801 formed at the end of the sealing tube 8. A sliding sleeve 12 connected to the connecting plate 10 is slidably mounted on the support rod 6. A sealing disc 13 is connected to the end of the sliding sleeve 12. The sealing disc 13 is sealed and fitted to the sealing tube 8. A second through hole 1301 is formed on the sealing disc 13, which is in communication with the first through hole 801.

[0055] Please see Figure 5 , Figure 6The support plate 5 is equipped with push rods 14 that are symmetrically distributed, and the end of the push rod 14 is connected to a sealing plug 16 that is slidably sealed to the discharge pipe 3.

[0056] Furthermore, the first through hole 801 and the second through hole 1301 are staggered. When the sealing plate 13 is tightly fitted with the sealing tube 8, both the first through hole 801 and the second through hole 1301 are blocked. A reinforcing plate 15 connected to the push rod 14 is installed on the support plate 5. Under the action of the reinforcing plate 15, the push rod 14 can move stably and synchronously with the support plate 5 when a strong air pressure is formed in the air box due to circuit abnormality.

[0057] Please see Figure 7 In the initial state, the support plate 5 and the first fixing ring 401 are in contact. In this state, the support plate 5 controls the sealing plug 16 to be located inside the discharge pipe 3 through the push rod 14, and the discharge pipe 3 is blocked under the action of the sealing plug 16. The sealing disc 13 and the sealing pipe 8 are in a close fit, so that the first through hole 801 and the second through hole 1301 are both in a blocked state. At this time, the distance between the limiting ring 7 and the connecting plate 10 is the largest, and the elongation of the second spring 11 in its natural state is greater than the maximum distance between the limiting ring 7 and the connecting plate 10. Therefore, the second spring 11 is in a pre-compressed state, and provides the sealing disc 13 with a thrust toward the direction of the sealing pipe 8 through the connecting plate 10 and the sliding sleeve 12.

[0058] Please see Figure 8 When the components inside the air box experience a continuous temperature rise due to an abnormal malfunction, the air pressure slowly increases, pushing the sealing tube 8 to move. This, in turn, drives the support plate 5 to move synchronously via the support rod 6. Under the action of the second spring 11, the connecting plate 10 moves synchronously with the support plate 5. The connecting plate 10 maintains its relative positional relationship with the sliding sleeve 12 and the sealing disc 13. The sealing disc 13 always maintains a sealed fit with the sealing tube 8. Slow pressure relief is achieved only through the micro-pressure relief channel between the outer wall of the sealing tube 8 and the conical chamber, maintaining the air box pressure within a safe range.

[0059] Please see Figure 9When a serious malfunction occurs inside the gas box, and the gas pressure rapidly spikes and exceeds the safety threshold in a short period of time, the sealing pipe 8 will move rapidly away from the gas box under high pressure. This will drive the support plate 5 to move via the support rod 6. The support plate 5 controls the connecting plate 10 to move rapidly via the limit ring 7 and the second spring 11. This allows the sealing disc 13 to move synchronously with the sealing pipe 8. When the connecting plate 10 moves to a position that fits against the bottom of the gas box, the position of the connecting plate 10 no longer changes, while the sealing pipe 8 remains in a moving state. Therefore, the second spring 11 is compressed, and the sealing disc 13 will separate from the sealing pipe 8, making the first through hole 801 and the second through hole 1301 connected. High-pressure gas can directly enter the sealing pipe 8 through the connected second through hole 1301 and the first through hole 801, and then exit the gas box from the sealing pipe 8, forming a high-flow-rate rapid pressure relief path.

[0060] As the sealing tube 8 continues to move, the conduction size formed by its cooperation with the conical chamber of the conical tube 2 also gradually increases. In this way, an effective pressure relief passage is formed both inside and outside the sealing tube 8, thereby ensuring rapid pressure relief of the gas box. At the same time, the support plate 5 drives the push rod 14 to push the sealing plug 16 completely out of the discharge pipe 3, further expanding the effective flow area of ​​the discharge passage. This allows the high-pressure gas in the gas box to be completely discharged in a short time, completely preventing the box 1 from bursting due to excessive pressure and protecting the safety of surrounding equipment and personnel.

[0061] The remote control dispatch module can acquire the displacement signal of the support plate 5 through the displacement sensor, thereby monitoring the pressure change status inside the air box in real time. When the displacement exceeds the preset warning threshold but does not trigger complete pressure relief, it can automatically send an abnormal alarm to the dispatch master station to remind maintenance personnel to remotely confirm the status and arrange on-site maintenance. When the complete pressure relief action is detected, it can automatically execute the remote control tripping isolation operation of the corresponding line to achieve rapid fault isolation and prevent the fault range from expanding.
