Description

Technical Field

[0001] The present invention relates to the technical field of ring main units, and particularly to an environmentally friendly feeder terminal gas-insulated ring main unit. Background Art

[0002] Ring main units are a type of electrical equipment widely used in power systems. They are usually equipped with a ring main unit gas chamber, and an insulating gas at a certain pressure is injected into it to ensure its safe operation. Currently, the insulating gas injected into the ring main unit gas chamber is mainly SF6 gas, which is widely used due to its excellent insulation and arc extinguishing performance. When an arc fault occurs in the ring main unit gas chamber, the gas pressure in the chamber will rise sharply. To relieve the pressure on the ring main unit gas chamber and ensure the safety of operators, a pressure relief device is usually installed on the ring main unit gas chamber so that the gas can be quickly discharged. Some environmentally friendly gas-insulated ring main units have changed the type of insulating gas, but in most cases, they cannot directly relieve pressure and discharge.

[0003] In the existing technology, when a fault occurs in the gas chamber of the ring main unit, the sharp increase in the gas pressure in the chamber will generate too much impact force, causing the pressure relief structure to collide, which is likely to damage the pressure relief device; in addition, the current pressure relief device does not process the relieved gas and directly discharges the gas into the air, which not only has an adverse impact on the environment but also poses potential safety risks. Therefore, in order to improve the safety and environmental friendliness of the ring main unit, it is necessary to improve the existing pressure relief device so that it can effectively process the relieved gas, reduce the impact on the environment, and improve the safety of operators.

[0004] Therefore, the present application proposes an environmentally friendly feeder terminal gas-insulated ring main unit to solve the problem. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an environmentally friendly feeder terminal gas-insulated ring main unit to solve the problems existing in the gas-insulated ring main unit in the above-mentioned existing technology.

[0006] To solve the above technical problems, the present invention provides the following technical solutions:

[0007] An environmentally friendly feeder terminal gas-insulated ring main unit, comprising a ring main unit body and a fixing frame arranged on the ring main unit body. A fixing seat is fixedly connected to the pressure relief port of the ring main unit body. A detachable first cylinder body is fixedly connected to the inner upper part of the fixing seat. A pressure relief mechanism is arranged in the first cylinder body, and the pressure relief mechanism is used to process the gas discharged from the pressure relief port. One end of the fixing frame is fixedly connected to a support frame, and a gas storage cylinder is arranged on the support frame, and the gas storage cylinder is used to collect the discharged gas.

[0008] As a further description of the above technical solution: The pressure relief mechanism includes a first slider and a second slider. One end of the first slider is fixedly connected with a piston block. Both the first slider and the second slider are located inside the first cylinder body, and a compression spring is arranged between the first slider and the second slider. One end of the second slider is rotatably connected with a lead screw, and the end of the lead screw far away from the second slider extends outwards through the first cylinder body. The lead screw is threadedly connected with the second slider, and a handle is fixedly connected to the end of the lead screw far away from the second slider. By setting the pressure relief mechanism, when the ring main unit relieves pressure through the pressure relief port, the gas inside it pushes the piston block outwards, causing the piston block to drive the first slider to slide outwards, gradually exposing and opening the air port. When the air port is communicated with the pressure relief port, the gas enters the second cylinder body through the first cylinder body, thus completing the pressure discharge. Moreover, by setting the lead screw and the compression spring, the rotation and movement of the lead screw can be controlled through the handle, and the lead screw drives the second slider to move. When the distance between the second slider and the first slider decreases, the compression spring is further compressed at this time, so that a greater pressure is required for the air pressure inside the ring main unit to be discharged. When the distance between the second slider and the first slider increases, the compression spring further expands at this time, so that a smaller pressure is required for the air pressure inside the ring main unit to be discharged.

[0009] As a further description of the above technical solution: The first slider is fixedly connected with the piston block, and hollow grooves are formed in both the first slider and the piston block. A cross baffle inserted into the piston block is fixedly connected inside the first slider. The cross baffle divides the hollow groove into a plurality of communicating grooves, and baffles are arranged at the outer ends of the plurality of communicating grooves. A first fastener and a number of second fasteners are installed on the baffle. The second fastener is made of nylon. The mouth of the gas storage cylinder is fixedly connected with an air collecting bag. The air collecting bag is located inside the gas storage cylinder. One end of the first cylinder body is fixedly connected with a second cylinder body, and an air port is formed between the first cylinder body and the second cylinder body. A bracket is fixedly connected inside the second cylinder body, and a rotating rod is rotatably connected inside the bracket. A plurality of fan blades are fixedly connected to the rotating rod. A number of connecting pipes are fixedly connected to the bottom end of the second cylinder body, and a gas storage cylinder is inserted and fixed on the plurality of connecting pipes. By setting the baffle, when a fault occurs inside the ring main unit and an explosion is triggered, the gas impacts the baffle. Since the baffle is fixed by nylon nails near the center position, the impact force causes the nylon nails to break, and the baffle immediately turns over. The gas quickly flows into the second cylinder body, pushing the fan blades to rotate. This not only helps to relieve the impact force but also realizes the pressure relief function.

[0010] As a further description of the above technical solution: a filling bladder is installed at the mouth of the gas storage cylinder. The cross-section of the filling bladder is a U-shaped structure. The filling bladder includes a filling area, and a gas guide pipe communicating with the second cylinder body is fixedly connected to the outer peripheral side wall of the filling bladder. By setting the filling bladder and installing the U-shaped filling bladder at the mouth of the gas storage cylinder, when a large amount of gas surges into the second cylinder body, part of the gas flows into the filling bladder through the gas guide pipe, causing the filling bladder to expand. The expanded filling bladder further seals the gap between the mouth of the bottle and the connecting pipe, effectively reducing gas leakage and enhancing the environmental protection performance. The above structure uses the gas itself to achieve further sealing without additionally adding structural components, which is beneficial to cost reduction.

[0011] As a further description of the above technical solution: one end of the rotating rod extends outward through the second cylinder body, and the rotating rod is rotatably connected to the second cylinder body. The other end of the fixed frame is fixedly connected with a micro power generation mechanism. The output end of the micro power generation mechanism and the outer end of the rotating rod are both fixedly connected with belt pulleys, and a belt is tensioned between the two belt pulleys. An alarm component is electrically connected to the micro power generation mechanism; when the fan blade drives the rotating rod to rotate, the belt pulley at its end activates the micro power generation mechanism through the transmission of the belt. Once the micro power generation mechanism is powered on, it starts the alarm component to issue an alarm reminder.

[0012] As a further description of the above technical solution: a sealing gasket is installed on the cross-shaped baffle. The sealing gasket is located between the cross-shaped baffle and the baffle piece. The sealing gasket is made of rubber to further seal the gap between the cross-shaped baffle and the baffle piece.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] In the above solution, by setting the pressure relief mechanism, when the ring main unit relieves pressure through the pressure relief port, the gas inside it pushes the piston block outward, gradually exposing and opening the air port. When the air port communicates with the pressure relief port, the gas enters the second cylinder body through the first cylinder body, thus completing the pressure discharge; and the distance between the second slider and the first slider can be adjusted to achieve the purpose of adjusting the pressure of the pressure relief mechanism, so as to facilitate adjustment according to needs and reduce the usage limitations.

[0015] By setting the baffle and the fan blade in the pressure relief mechanism, when an explosion occurs due to an internal fault in the main body of the ring main unit, the gas impacts the baffle, causing the baffle to open. At the same time, the gas quickly enters the second cylinder, and the gas entering the second cylinder drives the fan blade to rotate, thereby reducing part of the impact, achieving the effect of pressure relief, and reducing the problem of damage to the pressure relief mechanism caused by the impact; at the same time, the gas enters the airbag in the multiple gas storage cylinders through multiple connecting pipes, and the gas entering the airbag plays the role of pressure relief again, and the gas is collected by the gas storage cylinders, which is beneficial to subsequent treatment and improves environmental protection, effectively reducing the damage of the pressure relief mechanism caused by excessive impact; in addition, when the fan blade drives the rotating rod to rotate, the micro power generation mechanism can drive the alarm component, thereby giving an alarm reminder.

[0016] By setting the filling bag, the U-shaped filling bag is sleeved on the bottle mouth of the gas storage cylinder. When a large amount of gas enters the second cylinder, part of the gas enters the filling bag through the air guide pipe, causing the filling bag to expand. The expanded filling bag further fills the gap between the bottle mouth and the connecting pipe, reducing gas leakage, which is beneficial to improving environmental protection. The above structure is further sealed by gas, without adding additional structures, reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] As Figures 1-13 shown in the figure, an embodiment of the present invention provides an environmentally friendly feeder terminal gas-insulated ring main unit, which includes a ring main unit body 1 and a fixing frame 5 provided on the ring main unit body 1. A fixing seat 2 is fixedly connected to the pressure relief port of the ring main unit body 1. A detachable first cylinder 3 is fixedly connected to the inner upper part of the fixing seat 2. A pressure relief mechanism is provided inside the first cylinder 3. The pressure relief mechanism is used to process the gas discharged from the pressure relief port. One end of the fixing frame 5 is fixedly connected to a support frame 6. A gas storage cylinder 7 is provided on the support frame 6. The gas storage cylinder 7 is used to collect the discharged gas.

[0040] The pressure relief mechanism includes a first slider 8 and a second slider 10. One end of the first slider 8 is fixedly connected with a piston block 9. The first slider 8 and the second slider 10 are both located inside the first cylinder 3. An extrusion spring 11 is arranged between the first slider 8 and the second slider 10. One end of the second slider 10 is rotatably connected with a lead screw 12, and the end of the lead screw 12 away from the second slider 10 extends outwards through the first cylinder 3. The lead screw 12 is threadedly connected with the second slider 10. The end of the lead screw 12 away from the second slider 10 is fixedly connected with a handle 13. By setting the pressure relief mechanism, when the ring main unit 1 relieves pressure through the pressure relief port, the gas inside it will push the piston block 9 outwards, causing the piston block 9 to drive the first slider 8 to slide outwards, gradually exposing and opening the air port 15. When the air port 15 is communicated with the pressure relief port, the gas enters the second cylinder 4 through the first cylinder 3, thus completing the air pressure discharge; moreover, by setting the lead screw 12 and the extrusion spring 11, the rotation and movement of the lead screw 12 can be controlled through the handle 13, and the lead screw 12 drives the second slider 10 to move. When the distance between the second slider 10 and the first slider 8 is reduced, the extrusion spring 11 is further compressed at this time, so that a greater pressure is required for the air pressure inside the ring main unit 1 to be discharged. When the distance between the second slider 10 and the first slider 8 is increased, the extrusion spring 11 is further expanded at this time, so that a smaller pressure is required for the air pressure inside the ring main unit 1 to be discharged, thereby achieving the purpose of adjusting the pressure of the pressure relief mechanism, facilitating adjustment according to needs, and reducing the use limitations.

[0041] The first slider 8 and the piston block 9 are fixedly connected, and hollow grooves 23 are formed in both the first slider 8 and the piston block 9. A cross baffle 24 inserted into the piston block 9 is fixedly connected inside the first slider 8. The cross baffle 24 divides the hollow groove 23 into multiple communicating grooves 25, and baffles 27 are arranged at the outer ends of the multiple communicating grooves 25. A first fastener 28 and a number of second fasteners 29 are installed on the baffle 27. The second fasteners 29 are made of nylon. The mouth of the gas storage cylinder 7 is fixedly connected with an air collecting bag 19. The air collecting bag 19 is located inside the gas storage cylinder 7. One end of the first cylinder body 3 is fixedly connected with a second cylinder body 4, and an air port 15 is formed between the first cylinder body 3 and the second cylinder body 4. A bracket 17 is fixedly connected inside the second cylinder body 4. A rotating rod 14 is rotatably connected inside the bracket 17. A number of fan blades 16 are fixedly connected to the rotating rod 14. A number of connecting pipes 18 are fixedly connected to the bottom end of the second cylinder body 4. The gas storage cylinder 7 is inserted and fixed on the number of connecting pipes 18. By providing the baffle 27, when a fault occurs inside the ring main unit 1 and an explosion is triggered, the gas impacts the baffle 27. Since the baffle 27 is fixed by nylon nails near the center position, the impact force causes the nylon nails to break, and the baffle 27 immediately flips open. The gas quickly flows into the second cylinder body 4, pushing the fan blades 16 to rotate. This not only helps to relieve the impact force but also realizes the pressure relief function, thereby reducing the risk of damage to the pressure relief mechanism due to the impact. In addition, the gas enters the air collecting bag 19 in the multiple gas storage cylinders 7 through the multiple connecting pipes 18. Under normal conditions, the air collecting bag 19 is in a compressed state, and the entry of the gas further plays a role in pressure relief. The gas is collected by the gas storage cylinder 7, which is convenient for subsequent treatment and improves the environmental protection performance.

[0042] One end of the rotating rod 14 extends outward through the second cylinder body 4, and the rotating rod 14 is rotatably connected with the second cylinder body 4. The other end of the fixed frame 5 is fixedly connected with a micro power generation mechanism 32. Belt pulleys 30 are fixedly connected to the output end of the micro power generation mechanism 32 and the outer end of the rotating rod 14 respectively. A belt 31 is tensioned and connected between the two belt pulleys 30. An alarm component 33 is electrically connected to the micro power generation mechanism 32. When the fan blades 16 drive the rotating rod 14 to rotate, the belt pulley 30 at its end activates the micro power generation mechanism 32 through the transmission of the belt 31. Once the micro power generation mechanism 32 is powered on, it starts the alarm component 33 to issue an alarm reminder. In addition, the micro power generation mechanism 32 can be connected to a storage battery to extend the working time of the alarm component 33 and ensure continuous alarm function. The above-mentioned power generation mechanism and alarm component both belong to the category of existing technologies, and their connection methods and the collaborative working principles between each module will not be elaborated here.

[0043] A sealing gasket 26 is installed on the cross baffle 24. The sealing gasket 26 is located between the cross baffle 24 and the baffle 27. The sealing gasket 26 is made of rubber to further seal the gap between the cross baffle 24 and the baffle 27.

[0044] A filling bladder 20 is installed at the mouth of the gas storage cylinder 7. The cross-section of the filling bladder 20 is a U-shaped structure. The filling bladder 20 includes a filling area 21 inside, and an air guide pipe 22 communicating with the second cylinder body 4 is fixedly connected to the outer peripheral side wall of the filling bladder 20. By arranging the filling bladder 20, 20 sets of filling bladders with a U-shaped structure are installed at the mouth of the gas storage cylinder 7. When a large amount of gas surges into the second cylinder body 4, part of the gas flows into the filling bladder 20 through the air guide pipe 22, causing the filling bladder to expand. The expanded filling bladder further seals the gap between the mouth of the bottle and the connecting pipe 18, effectively reducing gas leakage and enhancing the environmental protection performance. The above structure uses the gas itself to achieve further sealing without the need to additionally increase structural components, which is beneficial to reducing costs.

[0045] The working principle of the technical solution provided by the present invention: In practical applications, the operator can appropriately adjust the pressure relief mechanism according to different usage scenarios. The operator can control the rotation and movement of the lead screw 12 by operating the handle 13. The rotation and movement of the lead screw 12 will drive the second slider 10 to move accordingly. When the distance between the second slider 10 and the first slider 8 gradually decreases, the compression spring 11 will be further compressed, so that a greater pressure is required for the air pressure inside the ring main unit 1 to be discharged; on the contrary, when the distance between the second slider 10 and the first slider 8 gradually increases, the compression spring 11 will further expand, so that the air pressure inside the ring main unit 1 can be discharged under a smaller pressure; when the ring main unit 1 needs to relieve pressure through the pressure relief port, the gas inside will push the piston block 9 to move outwards. The movement of the piston block 9 will drive the first slider 8 to slide outwards, so that the air port 15 is gradually opened. Once the air port 15 communicates with the pressure relief port, the gas will enter the second cylinder body 4 through the first cylinder body 3, thereby realizing the discharge of air pressure.

[0046] In the case of a malfunction and explosion inside the ring main unit 1, the impact force of the gas will directly act on the baffle 27. Since a nylon nail is used at the position of the baffle 27 close to the center, the baffle 27 will be broken when it receives a large enough impact force, so that a plurality of baffles 27 are all turned over, and the gas quickly enters the second cylinder body 4. The gas entering the second cylinder body 4 will push the fan blade 16 to rotate. This process helps to reduce part of the impact force and plays a role in relieving pressure, thereby reducing the risk of damage to the pressure relief mechanism due to impact; at the same time, the gas will also enter the air collecting bladder 19 in a plurality of gas storage cylinders 7 through a plurality of connecting pipes 18.

[0047] The present invention covers any alternatives, modifications, equivalent methods, and solutions made within the spirit and scope of the present invention. To enable the public to have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention. However, those skilled in the art can fully understand the present invention even without the description of these details. Additionally, well-known methods, processes, procedures, components, and circuits are not described in detail to avoid unnecessary confusion with the essence of the present invention.

[0048] The above description is only a preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
