Description

Technical Field

[0001] This invention relates to the field of smart grid technology, and more specifically, to a GIS high-voltage switch housing with a safety protection structure. Background Technology

[0002] The GIS high-voltage switchgear enclosure is a gas-insulated, metal-enclosed switchgear, comprising a grounded metal casing and an airtight container. It is a critical component integrating sealing, insulation, support, safety isolation, explosion-proofing, and shielding. The enclosure is filled with insulating gases such as SF6 and maintained at a certain pressure. SF6 is responsible for insulation between high-voltage conductors and between the conductors and the enclosure, and also helps extinguish arcs during circuit breaker interruption. The enclosure must be highly airtight; otherwise, a drop in pressure will severely reduce insulation and arc-extinguishing capabilities. It also houses busbars, circuit breakers, disconnecting switches, grounding switches, instrument transformers, surge arresters, etc., with the enclosure providing mechanical support and positioning for these components and ensuring a safe distance between the high-voltage conductors and the grounded enclosure.

[0003] In the prior art, the GIS high-voltage switch housing will age after long-term use. When the equipment ages and is bumped, the sealing outer ring will be damaged, causing small cracks or damage to the middle of the outer wall of the sealing outer ring. This will cause the SF6 gas filled inside the delivery pipe and connecting pipe to leak into the working environment, causing pollution to the working environment. Therefore, a GIS high-voltage switch housing with a safety protection structure is proposed. Summary of the Invention

[0004] This invention provides a GIS high-voltage switch housing with a safety protection structure, which can solve the problem mentioned in the background art of small cracks or damage in the middle of the outer wall of the sealing outer ring, causing the SF6 gas filled inside the delivery pipe and connecting pipe to leak into the working environment.

[0005] To achieve the above objectives, this solution provides a GIS high-voltage switch housing with a safety protection structure, including a housing mechanism. The housing mechanism includes a delivery pipe and a connecting pipe. A pressure display gauge is installed on the outside of the delivery pipe. A high-voltage bushing is connected above the surface of the delivery pipe. Fixing rings are fixedly connected to both ends of the inner walls of the delivery pipe and the connecting pipe. Several evenly distributed bolts are installed on the flange ends of both the delivery pipe and the connecting pipe. A sealing outer ring is installed between the delivery pipe and the connecting pipe via bolts. A sealing ring mechanism is installed inside the sealing outer ring. The sealing ring mechanism is used to compensate for and seal cracks caused by aging of the sealing outer ring and to provide emergency sealing for leaks. A support mechanism is also installed outside the sealing ring mechanism. The support mechanism applies pressure to the outer surface of the sealing outer ring to support and seal it, preventing internal SF6 gas leakage.

[0006] Optionally, the sealing ring mechanism includes two liner plates, both of which are fixed to the inner walls of the outer sealing ring on both sides. The outer surface of the outer sealing ring has mounting holes corresponding to the number of bolts. A sealing groove is provided in the gap between the two liner plates. The outer sealing ring is made of aluminum.

[0007] Optionally, a sealing inner ring is fixedly connected to the inner surface of the liner. The sealing inner ring is made of silicone and is shaped like a convex character. The protruding part of the sealing inner ring faces the sealing groove. An inner support plate is fixedly connected inside the sealing inner ring. The inner support plate is made of aluminum. Several evenly distributed fixed brackets are fixedly connected to the inner side wall of the liner. The inner support plate is slidably installed on the fixed brackets.

[0008] Optionally, the inner support plate has several evenly distributed conveying holes in the middle, a connecting pipe is fixedly connected below the inner sealing ring, the connecting pipe extends to the outer sealing ring, a central pipe is fixedly connected to the lower end of the connecting pipe, a side pipe is fixedly connected to one side of the central pipe, and the side pipe is connected to the inner sealing ring.

[0009] Optionally, a three-way valve is installed at the junction of the central pipe, connecting pipe and side pipe, an infusion port is connected to the lower end of the central pipe, an air pump is provided on the other side of the lower end of the central pipe, and a pressure valve is installed on one side of both the side pipe and the central pipe.

[0010] Optionally, the support mechanism includes a slide plate, which is slidably mounted on the outside of the sealing outer ring. Both ends of the slide plate are fixedly connected to fixed plates, and a liquid injection gun is mounted on the lower fixed plate.

[0011] Optionally, the upper surface of the fixed plate described below is fixedly connected to a mounting sheet metal, a lower connecting rod is rotatably mounted inside the mounting sheet metal, and an upper connecting rod is rotatably mounted at the upper end of the lower connecting rod.

[0012] Optionally, the upper connecting rod is slidably mounted on the upper fixed plate, a transmission component is rotatably mounted on the upper end of the upper connecting rod, a rotating rod is rotatably mounted on the upper end of the transmission component, a handle is fixedly connected to one side of the rotating rod, and screws are fixedly connected to both sides of the lower end of the rotating rod. The rotating rod is rotatably mounted on the upper fixed plate through the screws.

[0013] Optionally, nuts are threaded onto the screws on both sides, a connector is rotatably mounted on the lower end of the upper connecting rod, the connector and the lower connecting rod are coaxial, an outer sealing plate is fixedly connected to one end of the connector, sliders are fixedly connected to the upper and lower ends of the outer sealing plate, an installation groove is provided in the middle of the sliding plate, and the outer sealing plate is slidably installed in the installation groove by the slider.

[0014] Through the above technical solution, the GIS high-voltage switch housing with a safety protection structure provided by this solution is used as follows: When the inner sealing ring expands, its convex shape and protruding part located in the sealing groove between the two liner plates allow the repair fluid, located between the outer and inner sealing rings, to penetrate into the small gaps of the outer sealing ring. This is suitable for emergency repairs of the outer sealing ring, improving the stability of the housing. When the inner sealing ring contracts, its internal support plate provides support for the silicone inner sealing ring. Simultaneously, the support plate, with its delivery holes, moves along the fixed bracket, providing rigid support during contraction and sealing the sealing groove between the two liner plates. This not only repairs cracks but also, during contraction, the internal support plate's movement along the fixed bracket seals the sealing groove between the two liner plates, preventing internal SF6 leakage.

[0015] When the outer sealing ring is damaged or has small cracks, manually push the slide plate to rotate to the side that needs repair, aligning the mounting groove of the slide plate with the area to be repaired. Then, rotate the rotating rod by the handle. The rotation of the rotating rod, through the transmission component, pushes the upper connecting rod down along the fixed plate. Since the lower connecting rod is rotatably mounted at the lower end of the upper connecting rod and is rotatably connected to the mounting sheet metal, the upper and lower connecting rods fold together, pushing the outer sealing plate to move along the mounting groove. Subsequently, the outer sealing plate will tightly adhere to the outer wall of the outer sealing ring, sealing the external cracks and damage, improving the repair and protection effect of the shell, and preventing further SF6 gas leakage between the delivery pipe and the connecting pipe.

[0016] Other features and advantages of this solution will be described in detail in the following detailed implementation section. Attached Figure Description

Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings indicate the same or similar elements, which will not be repeated here.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this solution based on the specific circumstances.

[0022] According to some embodiments of this solution, a GIS high-voltage switch housing with a safety protection structure is provided, such as... Figures 1-8 As shown, the GIS high-voltage switch housing with a safety protection structure includes a housing mechanism 100, which includes a delivery pipe 101 and a connecting pipe 105. A pressure display gauge 102 is installed on the outside of the delivery pipe 101. A high-voltage bushing 103 is connected above the surface of the delivery pipe 101. Fixing rings 104 are fixedly connected to both ends of the inner walls of the delivery pipe 101 and the connecting pipe 105. Several evenly distributed bolts 106 are installed on the flange ends of both the delivery pipe 101 and the connecting pipe 105. A support bracket 400 is fixedly connected below the delivery pipe 101 and the connecting pipe 105. A protective housing 500 is fixedly attached to the upper surface of the support bracket 400. A sealing outer ring 107 is installed between the conveying pipe 101 and the connecting pipe 105 by bolts 106. A sealing ring mechanism 200 is installed inside the sealing outer ring 107. The sealing ring mechanism 200 is used to compensate for and seal cracks caused by aging of the sealing outer ring 107 and to provide emergency sealing for leaks. A support mechanism 300 is also installed outside the sealing ring mechanism 200. The support mechanism 300 is located inside the protective housing 500. The support mechanism 300 applies pressure to the outer surface of the sealing outer ring 107 to support and seal it, preventing internal SF6 gas leakage.

[0023] It should be noted that the bolt 106, in conjunction with the mounting hole 208 on the outer side of the sealing outer ring 107, can be installed between the conveying pipe 101 and the connecting pipe 105 to seal the connection between the conveying pipe 101 and the connecting pipe 105, preventing the SF6 gas filled inside the conveying pipe 101 and the connecting pipe 105 from leaking from the connection. The protective housing 500 is equipped with a support mechanism 300, which can protect it from dust and dirt.

[0024] like Figures 4-7As shown, the sealing ring mechanism 200 includes two bushings 210, both of which are fixed to the inner walls of the outer sealing ring 107. The outer surface of the outer sealing ring 107 has mounting holes 208 corresponding to the number of bolts 106. A sealing groove is provided between the two bushings 210. The outer sealing ring 107 is made of aluminum. An inner sealing ring 209, made of silicone, is fixedly connected to the inner surface of the bushings 210. The inner sealing ring 209 is convex in shape, with the protruding portion facing the sealing groove. An inner support plate 211, made of aluminum, is fixedly connected inside the inner sealing ring 209. Several evenly distributed fixing brackets 212 are fixedly connected to the inner wall of the bushings 210. The inner ring 209 is slidably mounted on the fixed bracket 212 via an inner support plate 211. Several evenly distributed delivery holes 201 are provided in the middle of the inner support plate 211. A connecting pipe 213 is fixedly connected to the lower part of the inner sealing ring 209. The connecting pipe 213 extends to the outside of the outer sealing ring 107. A central pipe 202 is fixedly connected to the lower end of the connecting pipe 213. A side pipe 203 is fixedly connected to one side of the central pipe 202. The side pipe 203 is connected to the inner sealing ring 107. A three-way valve 204 is installed at the junction of the central pipe 202, the connecting pipe 213 and the side pipe 203. An infusion port 206 is connected to the lower end of the central pipe 202. An air pump 207 is provided on the other side of the lower end of the central pipe 202. Pressure valves 205 are installed on one side of both the side pipe 203 and the central pipe 202.

[0025] To improve the sealing performance of the outer sealing ring 107, repair fluid can be added to the central tube 202 through the infusion port 206. Then, the three-way valve 204 is activated to deliver the repair fluid between the outer sealing ring 107 and the inner sealing ring 209 via the air pump 207. At the same time, the three-way valve 204 switches the air pump 207 to deliver air to the inner sealing ring 209 through the connecting tube 213. Since the inner sealing ring 209 is made of silicone, it will expand and contract. The three-way valve 204 switches the central tube 202 to connect to the connecting tube 213 and the side tube 203 respectively. This allows air to be delivered to the inner sealing ring 209 through the central tube 202 and the connecting tube 213, and the repair fluid can also be delivered between the inner sealing ring 209 and the outer sealing ring 107 through the side tube 203 via the three-way valve 204.

[0026] Furthermore, when the inner sealing ring 209 expands, because the inner sealing ring 209 is convex in shape and the protruding part faces the sealing groove between the two liner plates 210, and because the repair fluid is located between the outer sealing ring 107 and the inner sealing ring 209, the repair fluid can be pushed to penetrate into the small gaps of the outer sealing ring 107. This is suitable for emergency repairs of the outer sealing ring 107, improving the stability of the housing seal. When the inner sealing ring 209 contracts, the inner support plate 211 has a conveying hole 201 on its surface. Plate 211 can support the inner sealing ring 209 of silicone. The inner support plate 211 will move along the fixed bracket 212, thereby achieving the effect of rigid support during the shrinkage of the inner sealing ring 209, sealing the sealing groove between the two liner plates 210. This not only repairs cracks, but also seals the sealing groove between the two liner plates 210 by moving the inner support plate 211 along the fixed bracket 212 during shrinkage, thus preventing internal SF6 leakage.

[0027] It should be noted that when the GIS high-voltage switch housing is used for a long time, equipment aging will occur. When the equipment ages and is bumped, the sealing outer ring 107 will be damaged, causing small cracks or breakage in the sealing outer ring 107. Most of the problems with the sealing outer ring 107 are concentrated in the middle of the outer wall. The two liner plates 210 can limit the internal movement of the sealing outer ring 107, and the sealing inner ring 209 on the inner wall, together with the two liner plates 210, can also play a sealing role, achieving a double-layer sealing protection effect and improving the safety of the high-voltage switch housing.

[0028] like Figure 7As shown, the support mechanism 300 includes a slide plate 301, which is slidably mounted on the outside of the sealing outer ring 107. Fixed plates 302 are fixedly connected to both ends of the slide plate 301. A liquid injection gun 303 is mounted on the lower fixed plate 302. Mounting sheet metal 304 is fixedly connected to the upper surface of the lower fixed plate 302. A lower connecting rod 305 is rotatably mounted inside the mounting sheet metal 304. An upper connecting rod 309 is rotatably mounted on the upper end of the lower connecting rod 305. The upper connecting rod 309 is slidably mounted on the upper fixed plate 302. A transmission component 310 is rotatably mounted on the upper end of the upper connecting rod 309. A rotating rod 311 is rotatably mounted on the upper end of the transmission component 310. A handle 312 is fixedly connected to one side of the rotating rod 311. Screws 313 are fixedly connected to both sides of the lower end of the rotating rod 311. The rotating rod 311 is rotatably installed on the upper fixed plate 302 through the screws 313. Nuts 314 are installed on the screws 313 on both sides through threads. A connector 308 is rotatably installed on the lower end of the upper connecting rod 309. The connector 308 and the lower connecting rod 305 are coaxial. An outer sealing plate 306 is fixedly connected to one end of the connector 308. A slider 307 is fixedly connected to both the upper and lower ends of the outer sealing plate 306. An installation groove 315 is opened in the middle of the sliding plate 301. The outer sealing plate 306 is slidably installed in the installation groove 315 through the slider 307.

[0029] When it is necessary to add repair fluid, first place the liquid gun 303 on the fixed plate 302 below, and manually slide the slide plate 301 to rotate it to the side close to the infusion port 206, so that the liquid gun 303 can be inserted into the infusion port 206, thereby realizing the addition of repair fluid by the liquid gun 303, optimizing the convenience of the liquid replenishment process and improving the practicality of the housing.

[0030] It should be noted that when the outer sealing ring 107 is damaged or has small cracks, the sliding plate 301 is manually rotated to the side that needs repair, so that the mounting groove 315 of the sliding plate 301 is aligned with the part that needs repair. The handle 312 is then pushed to rotate the rotating rod 311. The rotation of the rotating rod 311, through the transmission component 310, pushes the upper connecting rod 309 down along the fixed plate 302. Since the lower connecting rod 305 is rotatably mounted on the lower end of the upper connecting rod 309, and the lower connecting rod 305 is rotatably connected to the mounting plate... The gold 304 causes the upper connecting rod 309 and the lower connecting rod 305 to fold. Since the connecting piece 308, the lower connecting rod 305 and the upper connecting rod 309 are coaxial, the outer sealing plate 306 can be pushed to move along the mounting groove 315. Subsequently, the outer sealing plate 306 will be tightly attached to the outer wall of the sealing outer ring 107, thereby sealing the cracks and damage on its exterior, improving the repair and protection effect of the housing, and preventing more SF6 gas leakage between the conveying pipe 101 and the connecting pipe 105.

[0031] In addition, the repair fluid in this case is an epoxy resin-based repair fluid. By adjusting the formula, low viscosity and high permeability can be achieved. It is suitable for fine cracks with a width of 0.1-0.5mm. The repair fluid is added to the central tube 202 through the inlet 206 and delivered to the space between the outer sealing ring 107 and the inner sealing ring 209 via the air pump 207 and the three-way valve 204. Subsequently, the inner sealing ring 209 expands and pushes the repair fluid to penetrate into the small gaps in the outer sealing ring 107. Then, with the help of the outer sealing plate 306, the repair fluid in the gap can be compressed and sealed, so that the repair fluid is located in the gap and completes the repair of the outer sealing ring 107.

[0032] The preferred embodiments of this solution have been described in detail above with reference to the accompanying drawings. However, this solution is not limited to the specific details in the above embodiments. Within the scope of the technical concept of this solution, various simple modifications can be made to the technical solution, and these simple modifications all fall within the protection scope of this solution.

[0033] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this solution will not describe the various possible combinations separately.

[0034] Furthermore, various implementations of this solution can be combined in any way, as long as they do not violate the spirit of this solution, they should also be regarded as the content disclosed in this solution.
