Description

Technical Field

[0001] The invention relates to the technical field of ring network cabinets, and in particular to an environmentally friendly feeder terminal gas-insulated ring network cabinet. Background Art

[0002] Ring main units are a type of electrical equipment that is very commonly used in power systems. They are usually equipped with a ring main unit gas chamber, into which a certain pressure of insulating gas is injected to ensure its safe operation. At present, the insulating gas injected into the ring main unit gas chamber is mainly SF6 gas, which is widely used for its excellent insulation and arc extinguishing performance. When an arc fault occurs in the ring main unit gas chamber, the gas pressure in the gas chamber will rise sharply. In order to relieve the pressure on the ring main unit gas chamber and ensure the safety of the 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 be directly discharged by pressure relief.

[0003] In the existing technology, when the air chamber of the ring main unit fails, the rapid increase in pressure in the air chamber will generate excessive impact force, causing the pressure relief structure to collide, which is easy to damage the pressure relief device; in addition, the current pressure relief device does not process the depressurized gas, but directly discharges the gas into the air, which not only has an adverse impact on the environment, but also poses a potential safety risk. Therefore, in order to improve the safety and environmental protection of the ring main unit, it is necessary to improve the existing pressure relief device so that it can effectively process the depressurized 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 above-mentioned problems of the insulated ring main unit in the prior art.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] An environmentally friendly feeder terminal gas insulated ring network cabinet comprises a ring network cabinet body and a fixing frame arranged on the ring network cabinet body, a fixing seat is fixedly connected to the pressure relief port of the ring network cabinet body, a detachable first cylinder is fixedly connected to the fixing seat, a pressure relief mechanism is arranged in the first cylinder, 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 supporting frame, a gas cylinder is arranged on the supporting frame, and the gas 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 to a piston block, the first slider and the second slider are both located in the first cylinder, and an extrusion spring is arranged between the first slider and the second slider, one end of the second slider is rotatably connected to a screw rod, and the end of the screw rod away from the second slider extends outward through the first cylinder, the screw rod and the second slider are threadedly connected, and the end of the screw rod away from the second slider is fixedly connected to a handle, and by setting the pressure relief mechanism, when the ring network cabinet body releases pressure through the pressure relief port, the internal gas pushes the piston block outward, so that the piston block is pushed outward. The plug drives the first slider to slide outward, so that the air port is gradually exposed and opened. When the air port and the pressure relief port are connected, the gas enters the second cylinder through the first cylinder, thereby completing the air pressure discharge; and, through the provided screw rod and extrusion spring, the screw rod can be controlled to rotate and move through the handle, and the screw rod drives the second slider to move. When the distance between the second slider and the first slider is reduced, the extrusion spring is further compressed, so that the air pressure in the ring network cabinet body needs a larger pressure to be discharged. When the distance between the second slider and the first slider increases, the extrusion spring is further expanded, so that the air pressure in the ring network cabinet body needs a smaller pressure to be discharged.

[0009] As a further description of the above technical solution: the first slider is fixedly connected to the piston block, and the first slider and the piston block are both provided with hollow grooves, a cross baffle inserted into the piston block is fixedly connected to the first slider, the cross baffle divides the hollow groove into a plurality of connecting grooves, and a baffle is provided at the outer ends of the plurality of connecting grooves, a first fastener and a plurality of second fasteners are installed on the baffle, the second fastener is made of nylon, an air collecting bag is fixedly connected to the bottle mouth of the gas storage bottle, the air collecting bag is located in the gas storage bottle, one end of the first cylinder is fixedly connected to the second cylinder, and the first cylinder and An air inlet is opened between the second cylinders, a bracket is fixedly connected to the second cylinder, a rotating rod is rotatably connected to the bracket, and a plurality of fan blades are fixedly connected to the rotating rod; a plurality of connecting pipes are fixedly connected to the bottom end of the second cylinder, and gas cylinders are plugged and fixed to the plurality of connecting pipes; by setting a baffle, when a fault occurs inside the ring network cabinet body and causes an explosion, the gas impacts the baffle, and as the baffle is fixed with nylon nails near the center, the impact force causes the nylon nails to break, and the baffle immediately flips open, and the gas quickly flows into the second cylinder to push the fan blades to rotate, which not only helps to alleviate the impact force, but also realizes the pressure relief function.

[0010] As a further description of the above technical solution: a filling bag is installed at the bottle mouth of the gas storage bottle, and the cross-section of the filling bag is a U-shaped structure. The filling bag includes a filling area, and the outer peripheral side wall of the filling bag is fixedly connected with an air guide tube connected to the second cylinder. By setting the filling bag, the filling bag with the U-shaped structure is installed at the bottle mouth of the gas storage bottle. When a large amount of gas flows into the second cylinder, part of the gas flows into the filling bag through the air guide tube, causing the filling bag to expand. The expanded filling bag further closes the gap between the bottle mouth and the connecting tube, effectively reducing gas leakage and enhancing environmental protection performance. The above structure uses the gas itself to achieve further sealing, without the need for additional structural components, which is conducive to reducing costs.

[0011] As a further description of the above technical solution: one end of the rotating rod extends outward through the second cylinder, and the rotating rod and the second cylinder are rotatably connected, the other end of the fixed frame is fixedly connected to a micro-generator mechanism, the output end of the micro-generator mechanism and the outer end of the rotating rod are fixedly connected to pulleys, a belt is tensioned between the two pulleys, and an alarm component is electrically connected to the micro-generator mechanism; when the fan blade drives the rotating rod to rotate, the pulley at its end activates the micro-generator mechanism through the transmission action of the belt, and once the micro-generator mechanism is energized, the alarm component is activated to issue an alarm reminder.

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

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

[0014] In the above scheme, by setting a pressure relief mechanism, when the ring network cabinet body releases pressure through the pressure relief port, the internal gas pushes the piston block outward, so that the gas port is gradually exposed and opened, and when the gas port and the pressure relief port are connected, the gas enters the second cylinder through the first cylinder, thereby completing the gas pressure discharge; and the purpose of adjusting the pressure of the pressure relief mechanism can be achieved by adjusting the distance between the second slider and the first slider, thereby facilitating adjustment according to needs and reducing usage limitations.

[0015] By setting the baffles and fan blades in the pressure relief mechanism, when an explosion occurs due to an internal fault in the ring network cabinet body, the gas impacts the baffle, causing the baffle to flip open, and at the same time the gas quickly enters the second cylinder. The gas entering the second cylinder drives the fan blades to rotate, thereby reducing part of the impact and achieving a pressure relief effect, thereby reducing the problem of damage to the pressure relief mechanism due to impact; at the same time, the gas enters the air collecting bags in the multiple gas cylinders through multiple connecting pipes. The gas entering the air collecting bags again achieves a pressure relief effect, and the gas is collected by the gas cylinders, which is beneficial to subsequent processing and improving environmental protection, and effectively reduces the damage to the pressure relief mechanism due to excessive impact; in addition, when the fan blades drive the rotating rod to rotate, the micro-generator can drive the alarm component to issue an alarm reminder.

[0016] By setting a filling bag, the U-shaped filling bag is placed on the bottle mouth of the gas storage bottle. When a large amount of gas enters the second cylinder, part of the gas enters the filling bag through the air guide tube, causing the filling bag to expand. After expansion, the gap between the bottle mouth and the connecting pipe is further filled, thereby reducing gas leakage and improving environmental protection. The above structure is further sealed by gas, and there is no need to add additional structure, thereby reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] like Figure 1-13 As shown in the figure, an embodiment of the present invention provides an environmentally friendly feeder terminal gas insulated ring network cabinet, including a ring network cabinet body 1 and a fixing frame 5 arranged on the ring network cabinet body 1, a fixing seat 2 is fixedly connected to the pressure relief port of the ring network cabinet body 1, a detachable first cylinder 3 is fixedly connected to the fixing seat 2, a pressure relief mechanism is arranged in the first cylinder 3, and 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 supporting frame 6, and a gas storage bottle 7 is arranged on the supporting frame 6, and the gas storage bottle 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 to a piston block 9, the first slider 8 and the second slider 10 are both located in the first cylinder 3, and 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 to a screw rod 12, and the end of the screw rod 12 away from the second slider 10 extends outward through the first cylinder 3, the screw rod 12 and the second slider 10 are threadedly connected, and the end of the screw rod 12 away from the second slider 10 is fixedly connected to a handle 13. By setting the pressure relief mechanism, when the ring network cabinet body 1 releases pressure through the pressure relief port, the internal gas pushes the piston block 9 outward, so that the piston block 9 drives the first slider 8 to slide outward, so that the air port 15 is gradually exposed and opened, and the air port 15 is gradually exposed and opened. 5 is connected to the pressure relief port, the gas enters the second cylinder 4 through the first cylinder 3, thereby completing the air pressure discharge; and, through the provided screw rod 12 and the extrusion spring 11, the screw rod 12 can be controlled to rotate and move through the handle 13, and the screw rod 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, so that the air pressure in the ring network cabinet body 1 needs a larger pressure 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, so that the air pressure in the ring network cabinet body 1 needs a smaller pressure to be discharged, thereby achieving the purpose of adjusting the pressure size of the pressure relief mechanism, facilitating adjustment according to needs, and reducing usage limitations.

[0041] The first slider 8 is fixedly connected to the piston block 9, and a hollow groove 23 is provided in the first slider 8 and the piston block 9. A cross baffle 24 inserted into the piston block 9 is fixedly connected in the first slider 8. The cross baffle 24 divides the hollow groove 23 into a plurality of connecting grooves 25, and a baffle 27 is provided at the outer ends of the plurality of connecting grooves 25. A first fastener 28 and a plurality of second fasteners 29 are installed on the baffle 27. The second fastener 29 is made of nylon. An air collecting bag 19 is fixedly connected to the bottle mouth of the gas storage bottle 7. The air collecting bag 19 is located in the gas storage bottle 7. One end of the first cylinder 3 is fixedly connected to the second cylinder 4, and an air port 15 is provided between the first cylinder 3 and the second cylinder 4. A bracket 17 is fixedly connected in the second cylinder 4. A rotating rod 14 is rotatably connected in the bracket 17. The rotating rod 14 is fixedly connected to the rotating rod 14. A plurality of fan blades 16 are fixedly connected; a plurality of connecting pipes 18 are fixedly connected to the bottom end of the second cylinder 4, and a gas cylinder 7 is plugged and fixed on the plurality of connecting pipes 18; by setting a baffle 27, when a fault occurs inside the ring network cabinet body 1 and an explosion occurs, the gas impacts the baffle 27. Since the baffle 27 is fixed with nylon nails near the center, the impact force causes the nylon nails to break, and the baffle 27 is immediately opened, and the gas quickly flows into the second cylinder 4, pushing the fan blades 16 to rotate, which not only helps to alleviate the impact force, but also realizes the pressure relief function, thereby reducing the risk of damage to the pressure relief mechanism due to impact. In addition, the gas enters the gas collecting bags 19 in the plurality of gas cylinders 7 through the plurality of connecting pipes 18. Under normal conditions, the gas collecting bags 19 are in a compressed state, and the entry of the gas further plays a role in pressure relief. Collecting the gas through the gas cylinder 7 facilitates subsequent processing and improves environmental protection performance.

[0042] One end of the rotating rod 14 extends outward through the second cylinder 4, and the rotating rod 14 is rotatably connected to the second cylinder 4. The other end of the fixed frame 5 is fixedly connected to a micro-generator 32. The output end of the micro-generator 32 and the outer end of the rotating rod 14 are fixedly connected to a pulley 30. A belt 31 is tensioned between the two pulleys 30. The micro-generator 32 is electrically connected to an alarm component 33. When the fan blade 16 drives the rotating rod 14 to rotate, the pulley 30 at its end activates the micro-generator 32 through the transmission action of the belt 31. Once the micro-generator 32 is powered on, the alarm component 33 is activated to issue an alarm reminder. In addition, the micro-generator 32 can be connected to a battery to extend the working time of the alarm component 33 and ensure a continuous alarm function. The above-mentioned power generation mechanism and alarm component belong to the scope of the prior art. The connection method between them and the cooperative working principle between the modules will not be described in detail 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 material and further seals the gap between the cross baffle 24 and the baffle 27 .

[0044] A filling bag 20 is installed at the mouth of the gas cylinder 7. The cross-section of the filling bag 20 is a U-shaped structure. The filling bag 20 includes a filling area 21, and the outer peripheral side wall of the filling bag 20 is fixedly connected to an air guide tube 22 connected to the second cylinder 4. By setting the filling bag 20, 20 sets of U-shaped filling bags are installed at the mouth of the gas cylinder 7. When a large amount of gas flows into the second cylinder 4, part of the gas flows into the filling bag 20 through the air guide tube 22, causing the filling bag to expand. The expanded filling bag further closes the gap between the bottle mouth and the connecting tube 18, effectively reducing gas leakage and enhancing environmental protection performance. The above structure uses the gas itself to achieve further sealing, without the need for additional structural components, which is conducive to reducing costs.

[0045] The working principle of the technical solution provided by the present invention is as follows: in actual application, the operator can make appropriate adjustments to the pressure relief mechanism according to different usage scenarios. The operator can control the rotation and movement of the screw rod 12 by operating the handle 13. The rotation and movement of the screw rod 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 extrusion spring 11 will be further compressed, so that the air pressure inside the ring network cabinet body 1 requires a larger pressure to be discharged; on the contrary, when the distance between the second slider 10 and the first slider 8 gradually increases, the extrusion spring 11 will be further expanded, so that the air pressure inside the ring network cabinet body 1 can be discharged under a smaller pressure; when the ring network cabinet body 1 needs to be depressurized through the pressure relief port, the internal gas will push the piston block 9 to move outward, and the movement of the piston block 9 will drive the first slider 8 to slide outward, so that the air port 15 gradually opens. Once the air port 15 is connected to the pressure relief port, the gas will enter the second cylinder 4 through the first cylinder 3, thereby realizing the discharge of air pressure.

[0046] In the event of a failure inside the ring network cabinet body 1 and an explosion, the impact force of the gas will directly act on the baffle 27. Since nylon nails are used near the center of the baffle 27, the baffle 27 will be broken when it is subjected to a sufficiently large impact force, so that multiple baffles 27 are flipped open, and the gas quickly enters the second cylinder 4. The gas entering the second cylinder 4 will push the fan blades 16 to rotate. This process helps to reduce some of the impact force and has a pressure relief effect, thereby reducing the risk of damage to the pressure relief mechanism due to impact. At the same time, the gas will also enter the gas collecting bags 19 in the multiple gas storage bottles 7 through the multiple connecting pipes 18.

[0047] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
