Description

Technical Field

[0001] This invention relates to the field of high-voltage grounding technology, specifically to a high-voltage disconnector grounding device. Background Technology

[0002] Grounding devices, also known as integrated grounding devices, are devices that establish an electrical connection between electrical equipment or other objects and the ground. Grounding devices consist of grounding electrodes (plates), grounding busbars (indoor and outdoor), grounding down conductors (grounding jumpers), and structural grounding. They are used to connect electrical systems to the earth. When a high-voltage disconnector is grounded, the operator typically drives the main shaft of the grounding switch via a handle to move the grounding blade to contact the stationary contact head of the high-voltage equipment. During this process, the grounding blade needs to pass the dead point of the spring inside the grounding device. At this moment, the pre-compressed spring will release its stored energy instantaneously, pushing the blade to contact the contact head. This causes the contact plate on the stationary contact head to insert into the blade, thus forming a low-resistance conductive circuit. Since the closing speed between the blade and the stationary contact head is determined by the spring's stored energy and is not affected by manual operation, and the instantaneous contact speed is relatively fast with a large instantaneous contact thrust, when the blade and the stationary contact head are interlocked, the instantaneous and large pushing force can easily cause deformation and misalignment between the blade and the stationary contact head, leading to poor contact and affecting the grounding efficiency of the subsequent discharge path. Summary of the Invention

[0003] The purpose of this invention is to provide a high-voltage disconnector grounding device to solve the problems mentioned in the background art.

An auxiliary mechanism is installed on the side wall of the contact mechanism to slow down the closing speed in the final stage of the contact mechanism's closing process.

[0005] Furthermore, the main body includes a stationary contact bolted to the top of the support, and the main body also includes: Support components are installed on the side wall of the main body to ensure the stability of the contact mechanism during the closing process; The resilient component is installed on the side wall of the support component to limit the closing speed of the contact mechanism when the support component is working.

[0006] Furthermore, the contact facilities include: Deformation component, which is installed on the side wall of the support component, is used to close the circuit when grounding is required; The limit component is installed on the side wall of the deformation component to prevent excessive wear between the deformation component and the stationary contact when the circuit is closed.

[0007] Furthermore, the auxiliary mechanism includes a C-shaped frame disposed on the outer surface of the deformation component, and the auxiliary mechanism also includes: The push component is installed on the side wall of the C-shaped frame; The active component is installed on the side wall of the push component.

[0008] Furthermore, the support assembly includes two connecting seats fixedly connected to the front of the main body, a central shaft rotatably connected between the two connecting seats, and three connecting plates fixedly connected to the outer surface of the central shaft; The connecting plates on the left and right sides are rotatably connected inside the connecting seat.

[0009] Furthermore, the elastic component includes a spring shaft rotatably connected inside the connecting seat, with one end of the spring shaft rotatably connected to the side wall of the connecting plate away from the connecting seat. Short rods are fixedly connected to both the left and right sides of the spring shaft, and limit plates are provided on both the left and right sides of the spring shaft. The limit plates are fixedly connected inside the connecting seat.

[0010] Furthermore, the deformation assembly includes a movable blade fixedly connected to the left and right sides of the connecting plate. The side wall of the movable blade is provided with a straight groove, and the front of the straight groove is provided with a notch. A long rod is fixedly connected between the two moving blades, and a grounding wire is bolted to the side wall of the leftmost and rightmost moving blades; The left moving blade has a right-angle groove on its side wall. The side wall of the moving blade in front of the groove is inclined and the top area of ​​the moving blade is initially bent.

[0011] Furthermore, the limiting component includes a right-angled block fixedly connected to the inner wall of the back of the straight groove, and an elastic plate is fixedly connected to the side of the right-angled block near the connecting plate; Two short rods are fixedly connected to the side of the right-angle block away from the connecting plate.

[0012] Furthermore, the C-shaped frame is slidably connected to the outer surfaces of the two moving blades; The actuating component includes a long plate rotatably connected to the back of the C-frame, with one end of the long plate rotatably connected to the side wall of the main body. Two vertical plates are fixedly connected to the top of the long plate, and the vertical plates are slidably connected inside the straight groove; The top of the C-shaped frame is fixedly connected to two diamond-shaped plates.

[0013] Furthermore, the movable component includes an inclined plate 1 fixedly connected to the side wall of the left moving blade, and the side wall of the inclined plate 1 has a rectangular groove. The rectangular groove has a sliding connection with a second inclined plate. The top of the second inclined plate is fixedly connected to the side wall of the right moving blade. The length of the second inclined plate is longer than that of the first inclined plate.

[0014] The present invention has the following beneficial effects: 1. In this invention, when the top areas of the two moving blades are close together, the top areas of the two moving blades can make tight contact with the side wall of the stationary contact. At the same time, it can reduce the collision deformation or misalignment between the moving blades and the stationary contact caused by the instantaneous and large pushing force generated between them, which could lead to poor contact. In this way, it can avoid the collision between the moving blades and the stationary contact when they are closed, and improve the grounding efficiency and stability of the grounding path during subsequent discharge of charge.

[0015] 2. This invention, by limiting the sliding speed of the C-shaped frame as it slides towards the top of the moving blade, can reduce the excessive impact of the moving blade on the side wall of the stationary contact or cause the moving blade to chatter when the two moving blades approach the stationary contact due to the excessive sliding speed of the C-shaped frame when the moving blade contacts the stationary contact. This ensures that the moving blade is stably clamped to the stationary contact while improving the continuity of subsequent grounding current transmission.

[0016] 3. The present invention, by forming this gap, enables the elastic plate to make close contact with the stationary contact, while also reducing excessive friction between the elastic plate and the stationary contact when the moving blade separates from the stationary contact. Furthermore, by forming this movable space, excessive friction on the stationary contact can be reduced, while also further absorbing the impact force when the moving blade approaches the stationary contact, ensuring the integrity of the stationary contact surface and further improving the contact strength when the moving blade and the stationary contact are in contact.

[0017] 4. By staggering the two ends of the moving blade and bringing it closer to the stationary contact, this invention can further ensure that the moving blade fits tightly and stably against the side wall of the stationary contact through the elastic plate, while also enhancing the stability of the contact between the two moving blades and the stationary contact and the clamping force on the stationary contact, and improving the connection efficiency of the moving blades and the stationary contact for closing and grounding.

[0022] 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.

[0023] Please see Figure 1 - Figure 8 As shown, the present invention is a high-voltage disconnector grounding device, including a main body 1, three supports 101 bolted to the top of the main body 1, and further including: Contact mechanism 2 is installed on the side wall of the main body 1 to prevent the support assembly 11 from colliding when the circuit is closed. Auxiliary mechanism 3 is installed on the side wall of contact mechanism 2 to slow down the closing speed in the final stage of the closing process of contact mechanism 2.

[0024] The main body 1 includes a stationary contact 102 bolted to the top of the support 101, and the main body 1 also includes: Support component 11 is installed on the side wall of the main body 1 to ensure the stability of the contact mechanism 2 during the closing process; The elastic component 12 is installed on the side wall of the support component 11 and is used to limit the closing speed of the contact mechanism 2 when the support component 11 is working.

[0025] Contact mechanism 2 includes: Deformation component 21 is installed on the side wall of support component 11 and is used to close the circuit when grounding is required; Limit component 22 is installed on the side wall of deformation component 21 to prevent excessive wear between deformation component 21 and stationary contact 102 when the circuit is closed.

[0026] The auxiliary mechanism 3 includes a C-shaped frame 301 disposed on the outer surface of the deformation component 21, and the auxiliary mechanism 3 also includes: Push component 31 is installed on the side wall of C-shaped frame 301; The active component 32 is mounted on the side wall of the push component 31.

[0027] The support assembly 11 includes two connecting seats 111 fixedly connected to the front of the main body 1, a central shaft 112 rotatably connected between the two connecting seats 111, and three connecting plates 113 fixedly connected to the outer surface of the central shaft 112. The connecting plates 113 on the left and right sides are rotatably connected inside the connecting seat 111. When grounding is required, the operator can rotate the central shaft 112 upwards using a tool. When the central shaft 112 rotates upwards, it will drive the moving blades 211 connected on both sides of the connecting plate 113 to rotate synchronously.

[0028] The elastic component 12 includes a spring shaft 121 rotatably connected inside the connecting seat 111, with one end of the spring shaft 121 away from the connecting seat 111 rotatably connected to the side wall of the connecting plate 113. Short rods are fixedly connected to both the left and right sides of the spring shaft 121. Limiting plates 122 are provided on both the left and right sides of the spring shaft 121. The limiting plates 122 are fixedly connected inside the connecting seat 111. When the central shaft 112 drives the connecting plate 113 to rotate, the rotation of the connecting plate 113 will generate a pulling force on the spring shaft 121. When the rotation of the central shaft 112 passes the dead point position of the limiting plate 122 on the spring shaft 121 via the short rods, the limiting plate 122 will be fixed.

[0029] The deformation assembly 21 includes a movable blade 211 fixedly connected to the left and right sides of the connecting plate 113. The side wall of the movable blade 211 is provided with a straight groove 212, and the front of the straight groove 212 is provided with a notch 213. A long rod is fixedly connected between the two moving blades 211, and a grounding wire 4 is bolted to the side wall of the leftmost and rightmost moving blades 211; The left moving blade 211 has a right-angle groove on its side wall. The side wall of the moving blade 211 located in front of the straight groove 212 is inclined and the top area of ​​the moving blade 211 is initially bent. When the pre-compressed spring shaft 121 releases its elastic potential energy and pushes the two moving blades 211 connected to it to rotate toward the stationary contact 102 through the connecting plate 113, the moving blades 211 on both sides of the connecting plate 113 will drive the C-shaped frame 301 on the outer surface to rotate synchronously.

[0030] The limiting component 22 includes a right-angle block 221 fixedly connected to the inner wall of the back side of the straight groove 212, and an elastic plate 222 is fixedly connected to the side of the right-angle block 221 near the connecting plate 113. A short rod is fixedly connected to the side of the right-angle block 221 away from the connecting plate 113. When the top area of ​​the moving blade 211 moves closer to the right-angle block 221, the inclined surface of the top area of ​​the moving blade 211 will move closer to the stationary contact 102 and deform slightly under the obstruction of the right-angle block 221.

[0031] C-shaped bracket 301 is slidably connected to the outer surfaces of the two moving blades 211; The pushing component 31 includes a long plate 311 rotatably connected to the back of the C-shaped frame 301, with one end of the long plate 311 away from the C-shaped frame 301 rotatably connected to the side wall of the main body 1; Two vertical plates 312 are fixedly connected to the top of the long plate 311, and the vertical plates 312 are slidably connected inside the straight groove 212; The top of the C-shaped frame 301 is fixedly connected to two diamond-shaped plates 313.

[0032] The movable component 32 includes an inclined plate 321 fixedly connected to the side wall of the left moving blade 211, and the side wall of the inclined plate 321 is provided with a rectangular groove. An inclined plate 322 is slidably connected inside the rectangular groove. The top of the inclined plate 322 is fixedly connected to the side wall of the right moving blade 211. The length of the inclined plate 322 is longer than that of the inclined plate 321. When the inclined plate 321 and the inclined plate 322 slide relative to each other, the bottom of the inclined plate 322 will be stuck in the right-angle groove on the left moving blade 211. Then, when the C-shaped frame 301 is about to slide to the top area of ​​the moving blade 211 and the moving blade 211 is about to contact the side wall of the stationary contact 102, the bottom of the inclined plate 322 will be blocked by the inner wall of the bottom of the right-angle groove, causing the inclined plate 322 to undergo a bending deformation.

[0033] In use, first connect the support 101 to the external high-voltage equipment, and simultaneously connect the grounding wire 4 to the ground. Then, when grounding is required, the operator uses a tool to rotate the central shaft 112 upwards. As the central shaft 112 rotates upwards, it drives the moving blades 211 connected to both sides of the connecting plate 113 to rotate synchronously. Simultaneously, when the central shaft 112 drives the connecting plate 113 to rotate, the rotation of the connecting plate 113 generates a pulling force on the spring shaft 121. When the rotation of the central shaft 112 passes the spring shaft 121... When the short rod is at the dead point of the limiting plate 122, the pre-compressed spring shaft 121 will instantly release the accumulated elastic potential energy and push the two moving blades 211 on the connecting plate 113 to rotate rapidly. At this time, the two moving blades 211 on the connecting plate 113 will contact the two side walls at the bottom of the stationary contact 102. A low-resistance conductive circuit can be formed between the moving blades 211 and the stationary contact 102. This circuit will quickly discharge the residual charge on the high-voltage equipment through the grounding wire 4 to achieve the purpose of grounding.

[0034] When the pre-compressed spring shaft 121 releases its elastic potential energy and pushes the two moving blades 211 connected to it to rotate toward the stationary contact 102 via the connecting plate 113, the moving blades 211 on both sides of the connecting plate 113 will drive the C-shaped frame 301 on the outer surface to rotate synchronously. Since the long plate 311 on the back of the C-shaped frame 301 is connected to the side wall of the main body 1 and the top areas of the two moving blades 211 are in a trumpet-shaped open state, when the moving blades 211 drive the C-shaped frame 301 to rotate, the C-shaped frame 301 will slide upward on the surface of the two moving blades 211 under the support of the long plate 311, and gradually close the tops of the two moving blades 211 together as they slide. When the blades 211 rotate toward the stationary contact 102, the opening distance between the tops of the two moving blades 211 will be greater than the contact end at the bottom of the stationary contact 102. Then, when the top areas of the two moving blades 211 approach each other, the top areas of the two moving blades 211 can tightly contact the side wall of the stationary contact 102. At the same time, it can reduce the collision deformation or misalignment between the moving blades 211 and the stationary contact 102 caused by the instantaneous and large pushing force generated between them, which could lead to poor contact. This can avoid the collision between the moving blades 211 and the stationary contact 102 when they are closed, and improve the grounding efficiency and stability of the grounding path during subsequent charge discharge.

[0035] When the C-shaped bracket 301 slides upward on the surfaces of the two moving blades 211 and pushes the tops of the two moving blades 211 closer together, the mutual approach of the tops of the two moving blades 211 will cause the inclined plate 1 321 and the inclined plate 2 322 to slide closer together. Since the length of the inclined plate 2 322 is longer than the length of the inclined plate 1 321, when the inclined plate 1 321 and the inclined plate 2 322 slide relative to each other, the bottom of the inclined plate 2 322 will be stuck in the right-angle groove on the left moving blade 211. Then, when the C-shaped bracket 301 is about to slide to the top area of ​​the moving blade 211 and the moving blade 211 is about to contact the side wall of the stationary contact 102, the bottom of the inclined plate 2 322 will be blocked by the inner wall of the bottom of the right-angle groove, causing the inclined plate 2 322 to undergo a bending deformation, presenting a certain shape. Figure 6As shown in position G, when the second inclined plate 322 deforms, the curvature of the surface of the second inclined plate 322 will push the first inclined plate 321 to tilt upward and contact the side wall of the right moving blade 211. At the same time, when the second inclined plate 322 deforms, the first inclined plate 321 will limit the approach speed of the two moving blades 211, so that the C-shaped frame 301 is about to slide to the top of the moving blade 211 in a relatively slow and stable sliding. By limiting the sliding speed of the C-shaped frame 301 in the area about to slide to the top of the moving blade 211, it can reduce the situation where the moving blade 211 excessively hits the side wall of the stationary contact 102 or causes the moving blade 211 to chatter when it approaches the stationary contact 102 due to the excessive sliding speed of the C-shaped frame 301 when the moving blade 211 contacts the stationary contact 102. This ensures that the moving blade 211 is stably clamped to the stationary contact 102 and improves the continuity of subsequent grounding current transmission.

[0036] When the rotating blade 211 causes the C-shaped frame 301 to slide upward on its surface, the sliding of the C-shaped frame 301 will drive the vertical plate 312 and the rhomboid plate 313 to rotate upward synchronously. When the C-shaped frame 301 drives the vertical plate 312 to slide upward, the top area of ​​the vertical plate 312 will push and squeeze the corner where the elastic plate 222 is connected to the rotating blade 211. When the vertical plate 312 squeezes the corner of the elastic plate 222, the elastic plate 222 will undergo an elastic deformation under the push of the vertical plate 312. When the elastic plate 222 deforms, the deformed area of ​​the elastic plate 222 will be in close contact with the side wall of the stationary contact 102, and at the same time, the elastic plate 222 will be in close contact with the side wall of the stationary contact 102. A movable gap is formed between the deformed end of the elastic plate 222 and the moving blade 211. This gap allows the elastic plate 222 to be in close contact with the stationary contact 102, while also reducing excessive friction between the elastic plate 222 and the stationary contact 102 when the moving blade 211 separates from the stationary contact 102. Furthermore, this movable space reduces excessive friction on the stationary contact 102 and further absorbs the impact force when the moving blade 211 approaches the stationary contact 102, ensuring the surface integrity of the stationary contact 102 while further improving the contact strength when the moving blade 211 contacts the stationary contact 102.

[0037] When the C-shaped frame 301 drives the rhomboid plate 313 and the vertical plate 312 to slide upward, the upward sliding of the rhomboid plate 313 will press against the surface of the short rod 2 on the side wall of the moving blade 211 through the inclined surface of its side wall. When the rhomboid plate 313 presses against the short rod 2, the short rod 2 will drive the inclined area at the top of the moving blade 211 to bend and approach the right-angle block 221 through the notch 213. When the top area of ​​the moving blade 211 approaches the right-angle block 221, the inclined surface of the top area of ​​the moving blade 211 will be blocked by the right-angle block 221 and move towards the stationary contact 102. The moving blade 211 moves closer and deforms slightly in the direction of the groove 212. At this time, the top of the moving blade 211 will form a staggered arrangement on both sides centered on the straight groove 212. Through the staggered arrangement of the two ends of the moving blade 211 and its approach towards the stationary contact 102, it can further ensure that the moving blade 211 is tightly and stably attached to the side wall of the stationary contact 102 through the elastic plate 222. At the same time, it can further enhance the stability of the contact between the two moving blades 211 and the stationary contact 102 and the clamping force on the stationary contact 102, while enhancing the connection efficiency of the closing ground between the moving blade 211 and the stationary contact 102.
