Abstract
Description
Technical Field
[0001] This utility model relates to the field of equalizing ring technology, specifically an equalizing ring for GIS equipment. Background Technology
[0002] Currently, equalizing rings are key components in high-voltage electrical systems and building lightning protection. They optimize the voltage distribution of insulator strings, forcibly adjust the voltage gradient of each node in the insulator string, prevent the first insulator from deteriorating due to overvoltage, improve the reliability of the insulation system, suppress local electric field distortion, and disperse the charge density on the surface of conductors or equipment through the ring conductor, thereby reducing corona discharge and local arc generation, and reducing power loss and electromagnetic interference.
[0003] Currently, equalizing rings are installed at the ends of insulator strings. However, some insulator strings are fixed at both ends, which makes the installation of the equalizing ring inconvenient. Since the equalizing ring is a closed ring, it is necessary to disassemble the insulator string to install the equalizing ring first, and then fix the insulator string again. Utility Model Content
[0004] This utility model provides an equalizing ring for GIS equipment. By using a mounting base, equalizing ring components, connecting pipes and connectors, the equalizing ring can be divided into multiple parts and fixed together using connecting pipes and connectors, thus facilitating its installation on insulator strings. Moreover, the fixing ring assembly is also composed of two half-ring components spliced together, allowing the equalizing ring to be directly installed and removed from the closed insulator string.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an equalizing ring for GIS equipment, comprising:
[0006] A terminal fixing base is provided with a fixing ring assembly fixed on one side of the outer wall of the terminal fixing base. Four connecting rods are fixed on one side of the outer wall of the fixing ring assembly. Four mounting bases are fixed on the ends of the four connecting rods away from the fixing ring assembly. Four pressure equalizing rings are fixed on one side of the outer wall of the four mounting bases. Four connecting tubes are slidably embedded between the four pressure equalizing rings.
[0007] As a pressure equalizing ring for GIS equipment according to this utility model, four connecting pieces are fixedly provided on the bottom of the outer wall of the four mounting bases, and the top of the outer wall of the four connecting pieces is fixedly provided on the four pressure equalizing ring pieces.
[0008] As a pressure equalizing ring for GIS equipment according to this utility model, the fixed ring assembly is composed of two half-ring pieces spliced together.
[0009] As a pressure equalizing ring for GIS equipment according to this utility model, the four connecting rods are all arranged at equal distances along the circumferential surface.
[0010] As a pressure equalizing ring for GIS equipment according to this utility model, the four mounting bases are all set at equal distances along the circumferential surface.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0019] Please see Figure 1-3 This utility model provides a technical solution: an equalizing ring for GIS equipment, comprising:
[0020] Terminal fixing base 1, a fixing ring assembly 2 is fixedly provided on one side of the outer wall of terminal fixing base 1, four connecting rods 3 are fixedly provided on one side of the outer wall of fixing ring assembly 2, four mounting bases 4 are fixedly provided at the ends of the four connecting rods 3 away from fixing ring assembly 2, four pressure equalizing rings 5 are fixedly provided on one side of the outer wall of the four mounting bases 4, and four connecting tubes 6 are slidably embedded between the four pressure equalizing rings 5.
[0021] In this implementation scheme: the terminal fixing seat 1 is used as the base for fixing the equalizing rings of the insulator string. When the four equalizing ring components 5 are close to each other, the four connecting pipes 6 are placed in sequence at the connection of the four equalizing ring components 5. Force is applied from all sides inward to make the four connecting pipes 6 embedded in the connection of the four equalizing ring components 5. When separating, force is applied from the center outward to disassemble. After being fixed together, the connection is reinforced by the four connecting pieces 7. The four mounting bases 4 are respectively fixed on the four equalizing ring components 5. After being fixed together, one end of the four connecting rods 3 is embedded into the fixing ring assembly 2 and fixed with bolts. The fixing ring assembly 2 is composed of two half-ring components 201 spliced together and fixed to the terminal fixing seat 1 with bolts. The equalizing ring is divided into multiple parts and fixed together by connecting pipes 6 and connecting pieces 7, so as to facilitate installation on the insulator string. Moreover, the fixing ring assembly 2 is also composed of two half-ring components 201 spliced together, so that the equalizing ring can be directly installed and removed on the closed insulator string.
[0022] Specifically, four connectors 7 are fixedly installed on the bottom of the outer wall of the four mounting bases 4, and the top of the outer wall of the four connectors 7 is fixedly installed on the four pressure equalizing rings 5.
[0023] In this embodiment, the four connectors 7 can reinforce the fixation between the four equalizing rings 5 and the four connecting pipes 6, and at the same time fix them on the four mounting bases 4, so that the four mounting bases 4 form a ring.
[0024] Specifically, the fixed ring assembly 2 is composed of two semi-ring parts 201 spliced together.
[0025] In this embodiment, the two semi-ring parts 201 can be used to allow the base to be fixed and spliced onto the insulator string.
[0026] Specifically, the four connecting rods 3 are all set at equal intervals along the circumferential surface.
[0027] In this embodiment, four pressure equalizing rings 5 are evenly distributed and fixed by four connecting rods 3.
[0028] Specifically, the four mounting bases 4 are all set at equal intervals along the circumferential surface.
[0029] In this embodiment, the connection is made more stable by using four mounting bases 4.
[0030] Specifically, the four equalizing rings 5 are all set at equal intervals along the circumferential surface.
[0031] In this embodiment, four equalizing ring components 5 can be spliced together to form an integral equalizing ring.
[0032] In use, the terminal fixing base 1 is a base specifically for fixing the equalizing rings of the insulator string. When the four equalizing ring pieces 5 are close to each other, the four connecting tubes 6 are placed in sequence at the connection of the four equalizing ring pieces 5. Force is applied from all sides inward to make the four connecting tubes 6 embedded in the connection of the four equalizing ring pieces 5. When separating, force is applied from the center outward to disassemble. After being fixed together, the connection is reinforced by the four connecting pieces 7. The four mounting bases 4 are respectively fixed on the four equalizing ring pieces 5. After being fixed together, one end of the four connecting rods 3 needs to be embedded into the fixing ring assembly 2 and fixed with bolts. The fixing ring assembly 2 is composed of two half-ring pieces 201 spliced together and fixed to the terminal fixing base 1 with bolts. The equalizing ring is divided into multiple parts and is fixed together by connecting tubes 6 and connecting pieces 7, which makes it convenient to put on the insulator string for installation. Moreover, the fixing ring assembly 2 is also composed of two half-ring pieces 201 spliced together, so that the equalizing ring can be directly installed and removed on the closed insulator string.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
