For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0070] The embodiment of the present application discloses a new grounding ring suitable for a 500kV substation.

[0071] See also Figures 1 to 5 An embodiment of a new grounding ring for a 500kV substation provided in the embodiments of the present application includes:

[0072] The grounding ring comprises a grounding ring body 1 , a clamping mechanism 3 , and a locking mechanism 4 and a hanging mechanism 2 which are sequentially arranged on the top of the grounding ring body 1 .

[0073] The hanging mechanism 2 is used to hang the grounding ring body 1 on the wire, the locking mechanism 4 is used to lock the grounding ring body 1, and the clamping mechanism 3 is arranged at the bottom of the outer wall of the grounding ring body 1, and is used to connect the grounding rod and the grounding ring body 1.

[0074] The hooking mechanism 2 includes a connection box 201, which is fixedly connected to the middle portion of the top wall of the grounding ring body 1. A conductive rod 205 is fixedly connected to the middle portion of the top wall of the connection box 201. A swivel 204 is rotatably connected to the middle portion of the outer wall of the conductive rod 205. Rotating rods 203 are rotatably connected to the left and right sides of the outer wall of the swivel 204. Fixed blocks 206 are fixedly connected to the outer walls of the two rotating rods 203 on the sides facing away from each other. First rotating shafts 202 are fixedly connected to the front and rear sides of the top walls of the two fixing blocks 206. Clamping brackets 210 are rotatably connected to the middle portions of the two front first rotating shafts 202.

[0075] The rotation of the swivel ring 204 provides horizontal rotational space for the clamping frame 210, while the rotation of the rotating rod 203 provides vertical rotational space for the clamping frame 210. By varying the spacing between the two clamping frames 210, the clamping frame 210 can be used to clamp wires at different angles, adapting to various field environments and wires at different angles. The locking mechanism 4 allows the grounding ring body 1 to be rotated while also locking its angle, thereby preventing damage to the wires caused by the rotation of the grounding ring body 1.

[0076] The clamping mechanism 3 includes a fixing plate 301 , the upper middle portion of the outer wall of the fixing plate 301 is fixedly connected to the bottom of the outer wall of the grounding ring body 1 , and the upper middle portions of the inner walls of the two fixing plates 301 are fixedly connected to limit rods 304 .

[0077] The clamping mechanism 3 can be used to clamp and fix the ground rod, thereby avoiding repeated hooking of the ground rod, reducing damage to the conductor caused by repeated hooking of the ground wire, saving time for repeated hooking due to loose hooking of the ground wire, ensuring that the ground rod is perpendicular to the ground, maximizing the manual operating torque, and hanging the ground wire more securely.

[0078] The above is the first embodiment of the new grounding ring for 500kV substation provided by the embodiment of the present application. The following is the second embodiment of the new grounding ring for 500kV substation provided by the embodiment of the present application. For details, please refer to Figures 1 to 10 .

[0079] Based on the solution of the above embodiment 1:

[0080] Furthermore, a bidirectional threaded rod 305 is provided at the middle and lower parts of the inner walls of the two fixing plates 301 , and the left end of the bidirectional threaded rod 305 is rotatably connected to the right side of the outer wall of the left fixing plate 301 .

[0081] The right end of the bidirectional threaded rod 305 passes through the fixed plate 301 on the right side, and the left and right sides of the outer wall of the bidirectional threaded rod 305 are threadedly connected with the threaded plates 302. The right end of the limiting rod 304 passes through the two threaded plates 302 in sequence, and the front and rear ends of the adjacent sides of the outer walls of the two threaded plates 302 are fixedly connected with the first clamping plate 303 and the second clamping plate 306 respectively.

[0082] By rotating the bidirectional threaded rod 305, under the limiting action of the limiting rod 304, the two threaded plates 302 are relatively close to each other, respectively driving the first clamping plate 303 and the second clamping plate 306 to be close to each other, thereby clamping the middle part of the ground rod. Under the rotation of the rotating rod 203, the ground rod is naturally vertical due to its own gravity, which maximizes the manual operating torque and makes it more secure to hang the ground wire. This saves time and repeats the hanging of the ground wire due to loose hanging, and reduces the damage of the wire caused by repeated hanging of the ground wire.

[0083] Furthermore, an elliptical drilled hole 209 is opened at the left and right ends of the outer wall of the two clamping frames 210, and a first bolt 208 is set inside the two elliptical drilled holes 209 on the left. The end of the first bolt 208 passes through the two elliptical drilled holes 209 in sequence and is threadedly connected to the first nut 207.

[0084] The elliptical drilled hole 209 provides a slight movement space for the first bolt 208 when the clamping frame 210 rotates, thereby preventing the first bolt 208 from obstructing the rotation of the clamping frame 210. By changing the matching position of the first nut 207 and the first bolt 208, the distance between the two clamping frames 210 is changed, so that the two clamping frames 210 clamp the internal wire clamp 11, and the wire clamp 11 clamps the wire, thereby completing the connection between the wire and the grounding ring body 1.

[0085] Furthermore, the locking mechanism 4 includes a ratchet disc 401 .

[0086] The ratchet disk 401 is fixedly connected to the lower middle part of the outer wall of the rotating ring 204, and the front end of the left side of the top wall of the connecting box 201 is fixedly connected to the first fixed column 402, and the top of the first fixed column 402 is rotatably connected to the stopping claw 403, and the left side of the outer wall of the stopping claw 403 is fixedly connected to the second rotating shaft 404, and the middle part of the second rotating shaft 404 is rotatably connected to the telescopic rod 407.

[0087] A second fixed column 406 is fixedly connected to the rear end of the left side of the top wall of the connecting box 201, and the left end of the telescopic rod 407 is fixedly connected to the upper middle part of the right side of the outer wall of the second fixed column 406. The outer wall of the telescopic rod 407 is provided with a spring 405, and the left end and the right end of the spring 405 are respectively fixedly connected to the left end and the right end of the outer wall of the telescopic rod 407, and the stopping claw 403 is engaged with the ratchet disk 401.

[0088] When the ratchet disc 401 rotates, the pawl 403 is squeezed, and the spring 405 contracts under the squeezing to give the pawl 403 space to rotate. When the ratchet disc 401 rotates to the empty slot 5 inside itself, the spring 405 returns to its original state, thereby driving the pawl 403 to rotate repeatedly with the rotation of the ratchet disc 401. When the pawl 403 is stuck inside the ratchet disc 401, the telescopic rod 407 is at its longest length. When the ratchet disc 401 has a tendency to rotate in the opposite direction, the telescopic rod 407 limits the rotation direction of the pawl 403, thereby completing the locking of the rotation angle of the swivel 204, and when the ratchet disc 401 rotates forward, it is necessary to squeeze the spring 405 to make it contract to reach a normal rotation state. The spring 405 itself has a certain elastic force, and the swivel 204 will not be rotated due to environmental factors such as wind, so that the wire connection effect is better.

[0089] Furthermore, a slot 8 is provided on the upper and middle parts of the adjacent sides of the outer walls of the two clamping frames 210, and a wire clamp 11 is provided on the left and right sides of the inner part of the slot 8. A plurality of circular drill holes 9 are provided on the outer walls of the two clamping frames 210 at equal intervals, and a second bolt 12 is provided inside the plurality of circular drill holes 9. The ends of the second bolts 12 pass through the clamping frames 210 and the wire clamp 11 in sequence and are threadedly connected with a second nut 10.

[0090] By changing the matching position of the second bolt 12 and the second nut 10, the distance between the two clamping frames 210 can be reduced, the clamping or loosening of the wire clamp 11 can be achieved, and the installation and removal of the wire clamp 11 can be achieved. By replacing different wire clamps 11, all wires that need to be grounded can be clamped, which expands the scope of use of the grounding ring body 1 and brings convenience to work.

[0091] Furthermore, the front and rear sides of the outer wall of the first clamping plate 303 are both provided with empty slots 5 , the front and rear sides of the inner wall of the second clamping plate 306 are both provided with rubber pads 14 , and the end of the second clamping plate 306 passes through the empty slots 5 .

[0092] Furthermore, the front and rear sides of the outer wall of the first splint 303 are provided with empty slots 5, the front and rear sides of the inner wall of the second splint 306 are provided with rubber pads 14, the end of the second splint 306 passes through the empty slot 5, the grounding ring body 1 adopts an integral bending molding design and is made of copper material, and the left and right sides of the outer wall of the grounding ring body 1 are provided with insulating rubber layers 13, the right end of the outer wall of the bidirectional threaded rod 305 is fixedly connected to the turntable 6, and the outer wall of the conductive rod 205 is provided with multiple grooves 7 at equal intervals.

[0093] The second clamping plate 306 can pass through the empty slot 5, further reducing the distance between the first clamping plate 303 and the second clamping plate 306, and expanding the size range of the grounding rod that can be clamped by the first clamping plate 303 and the second clamping plate 306. The rubber pad 14 increases the friction between the second clamping plate 306 and the clamped grounding rod, making the fixation of the grounding rod more stable. The copper material does not affect the normal operation of the wire on the basis of high conductivity. It adopts one-piece bending molding to reduce the connection interface and effectively reduce the heat generated by loose connection. By rotating the turntable 6, the bidirectional threaded rod 305 can be rotated more effortlessly. When the ratchet disk 401 rotates, it engages with the teeth of the stop claw 403. The wire can be rotatably placed in the groove 7, so that the connection effect between the wire and the conductive rod 205 is better, and the use effect of the grounding ring body 1 is better.

[0094] Working principle: The rotation of the swivel 204 itself provides the clamping frame 210 with movement space for rotation in the horizontal direction, and the rotation of the rotating rod 203 provides the clamping frame 210 with movement space for rotation in the vertical direction, thereby achieving the effect that wires at different angles can be connected to the grounding ring body 1. By changing the matching position of the first bolt 208 and the first nut 207, the spacing between the two clamping frames 210 is changed, so that they can clamp wires at different angles. The wires can be wrapped around the outer wall of the conductive rod to achieve the grounding purpose, which is suitable for a variety of on-site environments.

[0095] By replacing the wire clamp 11 between the two clamping frames 210, the grounding ring body 1 can be adapted to wires at different angles. Moreover, by rotating the bidirectional threaded rod 305, under the limiting action of the limiting rod 304, the two threaded plates 302 are relatively close to each other, respectively driving the first clamping plate 303 and the second clamping plate 306 close to each other, thereby clamping the middle part of the outer wall of the grounding rod. Under the rotation of the rotating rod 203, the grounding rod is naturally vertical due to its own gravity, so that the manual operating torque is maximized, and the grounding wire is hung more securely, saving time for repeated hanging due to loose grounding wire hanging, and reducing damage to the wire caused by repeated hanging of the grounding wire.

[0096] The above is a detailed introduction to the new grounding ring for 500kV substations provided by this application. For those skilled in the art, based on the ideas of the embodiments of this application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting this application.
