Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, specifically to an insulating spacer for gas-insulated electrical equipment. Background Technology

[0002] Gas-insulated electrical equipment, such as gas-insulated fully enclosed switchgear and gas-insulated transformers, has been widely used in high-voltage and ultra-high-voltage power transmission systems due to its significant advantages, including compact structure, small footprint, high operational reliability, and strong resistance to environmental interference. Bushings, as key insulating components connecting these devices to external overhead lines or power cables, play a crucial role in safely leading out or into the high-voltage, high-current system. Their structure typically spans the inner and outer sides of the equipment's metal casing, with the interior in direct contact with highly insulating gases such as SF6, while the exterior is constantly exposed to the atmosphere and faces complex and variable natural climatic conditions.

[0003] During continuous rainfall, rainwater easily accumulates at the edge of the bushing's skirt, forming a continuous water curtain or film. This conductive water layer electrically bridges adjacent skirts, effectively shortening the bushing's original creepage distance and causing a sharp increase in surface leakage current. Under the influence of the high-voltage operating electric field, the uneven heating of the leakage current will lead to the formation of a high-resistance dry band on the surface, inducing a localized electric arc. If the localized arc continues to extend and penetrates the entire surface path, it will eventually develop into a complete surface flashover, leading to the risk of uncontrolled leakage current. Summary of the Invention

Guided by the flow guiding component, the liquid will come into contact with the surface of the next insulating layer.

[0007] Preferably, the collection mechanism also includes; A rotating component is mounted on top of a fixed component. The discharge component is installed on the outer wall of the rotating component. When the liquid inside the rotating component is full, the rotating component will tilt, causing the liquid inside the rotating component to flow to the outer wall of the insulating layer.

[0008] Preferably, the fixing component includes several connecting rods fixedly connected to the outer wall of the base, and the side of the connecting rods near the insulating layer is fixedly connected to the outer wall of the fixing ring; The fixing rings are arranged in a linear array on the outer wall of the connecting rod, and a certain gap is pre-flowed between the fixing rings and the insulation layer.

[0009] Preferably, the connecting assembly includes an arc plate fixedly connected to the outer wall of the fixing ring on the side away from the base, and a partition plate fixedly connected to the outer wall of the fixing ring on the side away from the base, with the side of the partition plate away from the insulating layer being fixedly connected to the side of the arc plate that is close to the insulating layer. When the gas comes into contact with the first arc plate, it will be guided by the first arc plate into the gap between the insulation layer and the base.

[0010] Preferably, the flow guiding assembly includes a flow guiding plate fixedly connected to the side of the partition near the insulating layer, and the end of the flow guiding plate away from the partition is fixedly connected to the outer wall of the flow guiding plate; The gas entering between the insulation layer and the fixing ring will flow upward and contact the guide plate, and the gas that contacts the guide plate will move towards the outer wall of the insulation layer.

[0011] Preferably, the baffle assembly includes a corrugated plate fixedly connected to the side of the fixing ring near the base, and a plurality of air inlet holes are provided on the outer wall of the corrugated plate; The corrugated plate has a wave-shaped structure, and some gas will enter the gap between the insulation layer and the fixing ring through the air inlet.

[0012] Preferably, the rotating assembly includes a positioning post fixedly connected to the inner wall of the fixed ring, the outer wall of the positioning post being rotatably connected to the inner wall of the collection box, an air inlet groove being provided on the side of the collection box away from the insulating layer, and an arc-shaped plate being fixedly connected to the inner wall of the collection box. The collection box is only connected to the top fixing ring. Gas will come into contact with the outer wall of the discharge component through the air inlet slot. When the liquid inside the collection box is full, the collection box will rotate towards the insulating layer with the positioning column as the rotation center.

[0013] Preferably, the discharge assembly includes an elastic plate fixedly connected to the bottom of the collection box, the end of the elastic plate away from the collection box being fixedly connected to the outer wall of the fixing ring, a plurality of drip holes being provided on the outer wall of the collection box, a flap being rotatably connected to the inner wall of the collection box, a fixing plate being fixedly connected to the outer wall of the flap, the outer wall of the fixing plate being fixedly connected to the inner wall of the fixing ring, and an arc plate being fixedly connected to the inner wall of the collection box.

[0014] The elastic plate is flexible and has low elasticity. When the liquid inside the collection box is full, the elastic plate will bend and accumulate elastic potential energy.

[0015] The present invention has the following beneficial effects: (1) By setting up a collection box, rainwater will enter the collection box during rainy days. When the rainwater reaches a certain level, the collection box will rotate around the positioning column as the rotation center towards the direction of the insulation layer. At this time, a gap will appear between the collection box and the flap, and the liquid will flow out from the gap. The flowing liquid will wash the surface of the insulation layer. In this way, the rainwater will be prevented from forming a continuous conductive water film on the edge of the umbrella skirt of the insulation layer, thereby preventing the risk of leakage.

[0016] (2) By setting up the second arc plate, when the amount of rainwater is small, the rainwater will flow through the second arc plate to the side of the arc plate away from the insulation layer. At this time, the rainwater will enter the drip hole and drip slowly down along the inside of the drip hole. In this way, when there is a small amount of rainwater, the liquid will be discharged from the drip hole, preventing the poor fluidity on the surface of the insulation layer when there is little rainwater and the inability to be quickly evaporated by the gas. In the long run, the rainwater will penetrate the insulation layer, thereby accelerating the aging of the insulation layer.

[0017] (3) By setting an air inlet, when the gas enters the gap between the insulating layer and the fixing ring through the arc plate, the gas will rotate on the surface of the insulating layer and then flow out from the air inlet. When the gas flow rate is fast, because the air inlet is small and some air inlets are also in the air at the same time, the gas entering the gap between the insulating layer and the fixing ring will flow out towards the top of the insulating layer. During the gas flow, it will come into contact with the guide plate, which will guide the gas to flow towards the direction of the insulating layer. In this way, the evaporation of moisture is accelerated and the risk of leakage current under humid conditions is reduced.

[0018] (4) By setting a diversion plate, when the liquid flows out from the first surface of the insulation layer, it will come into contact with the diversion plate. Under the guidance of the diversion plate, the liquid will first move closer to the surface of the insulation layer. At this time, the liquid flows onto the second surface of the insulation layer. In this way, the diversion plate guides the water flow step by step, so that the water flow impacts the lower surface of the umbrella skirt and prevents impurities in the dead area of ​​the umbrella skirt from being unable to be removed.

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.

[0023] Example 1, please refer to Figures 1-6 The present invention relates to an insulating spacer for gas-insulated electrical equipment, comprising a base 12, a connector 13 fixedly connected to the bottom of the base 12, and an insulating layer 14 fixedly connected to the top of the base 12, and further comprising: Fixing mechanism 2 is installed on the outer wall of base 12, and fixing mechanism 2 includes fixing ring 212; The flow guiding mechanism 3 is installed at the bottom of the fixed mechanism 2, and the flow guiding mechanism 3 includes a flow guiding plate 312; Collection mechanism 4 is installed on top of fixing mechanism 2, and collection mechanism 4 includes collection box 412; When it rains, rainwater enters the top of the collection mechanism 4. When the liquid content inside the collection mechanism 4 increases to a certain level, the collection mechanism 4 will tilt at a certain angle, so that the rainwater inside flows out and comes into contact with the surface of the insulation layer 14.

[0024] Fixed mechanism 2 also includes: Fixing component 21 is installed on the outer wall of base 12; Connecting component 22 is installed on the outer wall of fixing ring 212; The flowing gas portion will come into contact with the outer wall of the arc plate 221, and under the guidance of the connecting component 22, it will come into contact with the surface of the insulating layer 14.

[0025] Example 2, please refer to Figures 2-9 The present invention is an insulating spacer for gas-insulated electrical equipment. Based on Embodiment 1, the flow guiding mechanism 3 further includes: The flow guiding component 31 is installed on the inner wall of the connecting component 22; The flow-blocking component 32 is installed at the bottom of the fixed component 21; When the liquid leaves the first insulating layer 14, it flows downward and contacts the flow guiding component 31. Guided by the flow guiding component 31, the liquid will contact the surface of the next insulating layer 14.

[0026] Collection agency 4 also includes; Rotating component 41 is mounted on top of fixed component 21; Discharge assembly 42 is installed on the outer wall of rotating assembly 41; When the liquid inside the rotating assembly 41 is full, the rotating assembly 41 will tilt, causing the liquid inside the rotating assembly 41 to flow to the outer wall of the insulating layer 14.

[0027] The fixing component 21 includes several connecting rods 211 fixedly connected to the outer wall of the base 12. The side of the connecting rods 211 near the insulating layer 14 is fixedly connected to the outer wall of the fixing ring 212. Among them, the fixing rings 212 are arranged in a linear array on the outer wall of the connecting rod 211, and a certain gap is pre-flowed between the fixing rings 212 and the insulating layer 14.

[0028] The connecting component 22 includes an arc plate 221 fixedly connected to the outer wall of the fixing ring 212 away from the base 12. A partition 222 is fixedly connected to the outer wall of the fixing ring 212 away from the base 12. The side of the partition 222 away from the insulating layer 14 is fixedly connected to the side of the arc plate 221 close to the insulating layer 14. When the gas comes into contact with the arc plate 221, it will be guided by the arc plate 221 into the gap between the insulating layer 14 and the base 12.

[0029] The flow guiding assembly 31 includes a flow guiding plate 311 fixedly connected to the side of the partition 222 near the insulating layer 14, and the end of the flow guiding plate 311 away from the partition 222 is fixedly connected to the outer wall of the flow guiding plate 312. The gas entering between the insulation layer 14 and the fixing ring 212 flows upward and contacts the guide plate 312. The gas that contacts the guide plate 312 moves towards the outer wall of the insulation layer 14. By setting the guide plate 311, when the liquid flows out from the first surface of the insulation layer 14, it contacts the guide plate 311. Under the guidance of the guide plate 311, the liquid moves towards the surface of the insulation layer 14 first. At this time, the liquid flows onto the second surface of the insulation layer 14. In this way, the guide plate 311 guides the water flow step by step, so that the water flow impacts the lower surface of the umbrella skirt and prevents impurities in the dead zone of the umbrella skirt from not being removed.

[0030] The flow deflector assembly 32 includes a corrugated plate 321 fixedly connected to the fixed ring 212 on the side near the base 12, and a plurality of air inlet holes 322 are provided on the outer wall of the corrugated plate 321. The corrugated plate 321 has a wave-shaped structure, and some gas enters the gap between the insulating layer 14 and the fixing ring 212 through the air inlet 322. By setting the air inlet 322, when the gas enters the gap between the insulating layer 14 and the fixing ring 212 through the arc plate 221, the gas will rotate on the surface of the insulating layer 14 and then flow out from the air inlet 322. When the gas flow rate is fast, because the air inlet 322 is small and some of the air inlets 322 are also taking in air at the same time, the gas entering the gap between the insulating layer 14 and the fixing ring 212 will flow towards the top of the insulating layer 14. During the gas flow, it will come into contact with the guide plate 312, which will guide the gas to flow closer to the insulating layer 14. In this way, the evaporation of moisture is accelerated, reducing the risk of leakage current under humid conditions.

[0031] The rotating assembly 41 includes a positioning post 411 fixedly connected to the inner wall of the fixing ring 212. The outer wall of the positioning post 411 is rotatably connected to the inner wall of the collection box 412. An air inlet groove 413 is provided on the side of the collection box 412 away from the insulating layer 14. An arc plate 414 is fixedly connected to the inner wall of the collection box 412. The collection box 412 is only connected to the top fixing ring 212. Gas will come into contact with the outer wall of the discharge component 42 through the air inlet groove 413. When the liquid inside the collection box 412 is full, the collection box 412 will rotate towards the insulating layer 14 with the positioning post 411 as the rotation center. By setting the collection box 412, rainwater will enter the collection box 412 during rainy days. When the rainwater reaches a certain level, the collection box 412 will rotate towards the insulating layer 14 with the positioning post 411 as the rotation center. At this time, a gap will appear between the collection box 412 and the flap 424. The liquid will flow out from the gap and wash the surface of the insulating layer 14. In this way, the rainwater will be prevented from forming a continuous conductive water film on the edge of the umbrella skirt of the insulating layer 14, thus preventing the risk of leakage.

[0032] The discharge assembly 42 includes an elastic plate 421 fixedly connected to the bottom of the collection box 412. The end of the elastic plate 421 away from the collection box 412 is fixedly connected to the outer wall of the fixing ring 212. Multiple drip holes 422 are provided on the outer wall of the collection box 412. A flap 424 is rotatably connected to the inner wall of the collection box 412. A fixing plate 423 is fixedly connected to the outer wall of the flap 424. The outer wall of the fixing plate 423 is fixedly connected to the inner wall of the fixing ring 212. An arc plate 425 is fixedly connected to the inner wall of the collection box 412.

[0033] Among them, the elastic plate 421 is flexible and has a small elastic force. When the liquid inside the collection box 412 is full, the elastic plate 421 will bend and accumulate elastic potential energy. By setting the second arc plate 425, when the amount of rainwater is small, the rainwater will flow through the second arc plate 425 to the side of the arc plate 414 away from the insulation layer 14. At this time, the rainwater will enter the drip hole 422 and drip slowly down along the inside of the drip hole 422. In this way, when there is a small amount of rainwater, the liquid will be discharged from the drip hole 422, preventing the poor fluidity of the liquid on the surface of the insulation layer 14 when the amount of rainwater is small and it cannot be quickly evaporated by the gas. Over a long period of time, the rainwater will penetrate the insulation layer 14, thereby accelerating the aging of the insulation layer 14.

[0034] One specific application of this embodiment is: before starting work, the operator connects connector 13 to the gas chamber of the gas-insulated electrical equipment.

[0035] At the start of operation, because connector 13 is installed externally, and in rainy weather, rainwater will first contact the surface of arc plate 425. The liquid will then slide down the surface of arc plate 425 to the side of arc plate 414 away from insulation layer 14. At this point, the liquid will enter arc plate 414 and slowly drain out. As the rainfall increases, the drainage efficiency of drip hole 422 cannot keep up with the water inflow efficiency, causing the liquid level inside collection box 412 to rise. As the liquid level inside collection box 412 continues to rise, the weight of the side of collection box 412 closest to insulation layer 14 will increase. At this point, collection box 412 will rotate towards the direction closer to insulation layer 14, and the spring... The elastic plate 421 will also begin to bend and accumulate elastic potential energy. As the collection box 412 rotates, a drainage gap will be formed between the collection box 412 and the flap 424. At this time, the liquid will flow out from the drainage gap of the flap 424, and the outflowing liquid will come into contact with the first surface layer of the insulating layer 14. When the liquid flows through the first surface layer, it will flow downward. At this time, the liquid will come into contact with the guide plate 311, and the guide plate 311 will guide the liquid again, so that the liquid moves closer to the second surface layer of the insulating layer 14. Repeat the above operation so that multiple surfaces on the insulating layer 14 can be flushed. When the weight of the collection box 412 is reduced, the elastic plate 421 will release elastic potential energy, thereby causing the collection box 412 to reset again. When the gas flows around the fixed ring 212, some of the gas will come into contact with the arc plate 221, allowing the gas to enter the gap between the insulating layer 14 and the fixed ring 212 through the arc plate 221. The gas entering the gap will first rotate on the surface of the insulating layer 14. As the gas continues to enter the gap, it will be unable to move laterally. At this time, the gas in the gap will start to move upward. During the upward movement of the gas, some of the gas will enter the gap between the base 12 and the fixed ring 212 through the air inlet 322 on the surface of the corrugated plate 321. This will push the gas that was originally in the gap connecting component 22 by the gas in the air inlet 322. Under the guidance of the guide plate 312, the gas will move towards the surface of the insulating layer 14. As the gas flows on the surface of the insulating layer 14, the water vapor on the surface of the insulating layer 14 will evaporate rapidly, and the gas will flow out from the top of the insulating layer 14.

[0036] By setting up the collection box 412, rainwater will enter the collection box 412 during rainy days. When the rainwater reaches a certain level, the collection box 412 will rotate around the positioning post 411 as the rotation center and move towards the insulating layer 14. At this time, a gap will appear between the collection box 412 and the flap 424, and the liquid will flow out from the gap. The flowing liquid will wash the surface of the insulating layer 14. In this way, it is prevented that rainwater forms a continuous conductive water film on the edge of the umbrella skirt of the insulating layer 14, thereby preventing the risk of leakage.

[0037] By setting the diversion plate 311, when the liquid flows out from the first surface of the insulation layer 14, it will come into contact with the diversion plate 311. Under the guidance of the diversion plate 311, the liquid will first move towards the surface of the insulation layer 14. At this time, the liquid flows onto the second surface of the insulation layer 14. In this way, the diversion plate 311 guides the water flow step by step, so that the water flow impacts the lower surface of the umbrella skirt, preventing impurities in the dead zone of the umbrella skirt from not being removed.

[0038] By setting up the second arc plate 425, when the amount of rainwater is small, the rainwater will flow through the second arc plate 425 to the side of the arc plate 414 away from the insulation layer 14. At this time, the rainwater will enter the drip hole 422 and drip slowly down along the inside of the drip hole 422. In this way, when there is a small amount of rainwater, the liquid will be discharged from the drip hole 422, preventing the poor fluidity of the rainwater on the surface of the insulation layer 14 when there is little rainwater and the inability to be quickly evaporated by the gas. Over a long period of time, the rainwater will penetrate the insulation layer 14, thereby accelerating the aging of the insulation layer 14.

[0039] By setting the air inlet 322, when the gas enters the gap between the insulating layer 14 and the fixing ring 212 through the arc plate 221, the gas will rotate on the surface of the insulating layer 14 and then flow out from the air inlet 322. When the gas flow rate is fast, because the air inlet 322 is small and some of the air inlets 322 are also inlet at the same time, the gas entering between the insulating layer 14 and the fixing ring 212 will flow out towards the top of the insulating layer 14. During the gas flow, it will come into contact with the guide plate 312, which will guide the gas to flow closer to the insulating layer 14. In this way, the evaporation of moisture is accelerated, reducing the risk of leakage current under humid conditions.
