Description

Technical Field

[0001] This utility model relates to the field of equalizing ring technology, specifically a ring-shaped equalizing ring. Background Technology

[0002] An equalizing ring for insulators is a ring-shaped or elliptical metal tube installed at both ends (usually the high-voltage end) of a high-voltage insulator string (or composite insulator). Its main purpose is to improve the voltage distribution of the insulator string, thereby protecting the insulator from arc burns and improving its overall electrical performance.

[0003] Currently, some annular equalizing rings have their connecting rods directly welded to the ring body, making them impossible to separate and resulting in low flexibility. Others connect the connecting rods to the fixing plates on the ring body using bolts and nuts. However, the traditional structure of connecting a single fixing plate to the connecting rod can easily lead to poor stability of the connecting rod. Therefore, an improved technology is urgently needed to solve this problem in the existing technology. Summary of the Invention

[0004] The purpose of this invention is to provide an annular equalizing ring to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an annular equalizing ring, comprising a ring body, connecting rods, and fixing plates. Two fixing plates are provided on each side of one end of the ring body, with a gap between the two fixing plates on the same side. A straight connecting plate is provided at one end of the connecting rod, and an arc-shaped connecting plate is provided at the other end of the connecting rod. There are two connecting rods. The straight connecting plate of one connecting rod is located between the two fixing plates on one side of the ring body and is fastened to the corresponding two fixing plates by bolts and nuts. The straight connecting plate of the other connecting rod is located between the two fixing plates on the other side of the ring body and is fastened to the corresponding two fixing plates by bolts and nuts. The arc-shaped connecting plates of the two connecting rods cooperate with each other and are fastened together by two sets of bolts and nuts.

[0006] Preferably, the present invention provides an annular equalizing ring in which the distance between two fixing plates on the same side is consistent with the thickness of the straight connecting plate, and each fixing plate is provided with a first connecting hole.

[0007] Preferably, the present invention provides an annular equalizing ring, wherein the straight connecting plate has a second connecting hole, and the second connecting hole is connected to the first connecting hole by a bolt.

[0008] Preferably, the present invention provides an annular equalizing ring, wherein the arc-shaped connecting plate has two third connecting holes, and the third connecting holes of the two connecting rods correspond one-to-one and are connected by bolts.

[0009] Preferably, in the annular equalizing ring provided by this utility model, the fixing plates are all connected to the ring body by welding.

[0010] Compared with the prior art, the beneficial effects of this utility model are: Two fixing plates are provided on each side of the ring body, and a gap is left between the two fixing plates on the same side to allow for the insertion and mating of the straight connecting plate of the connecting rod. At the same time, bolts and nuts are used to fasten the straight connecting plate between the corresponding two fixing plates.

[0014] Please see Figure 1-4This utility model provides a technical solution: an annular equalizing ring, including a ring body 1, a connecting rod 2, and a fixing plate 3. Two fixing plates 3 are provided on each side of one end of the ring body 1. The fixing plates 3 are connected to the ring body 1 by welding to realize the connection between the fixing plates 3 and the ring body 1. A gap is left between the two fixing plates 3 located on the same side. A straight connecting plate 4 is provided at one end of the connecting rod 2, and an arc-shaped connecting plate 5 is provided at the other end of the connecting rod 2. There are two connecting rods 2. The straight connecting plate 4 of one connecting rod 2 is located between the two fixing plates 3 on one side of the ring body 1 and is fastened to the corresponding two fixing plates 3 by bolts and nuts. The straight connecting plate 4 of the other connecting rod 2 is located between the two fixing plates 3 on the other side of the ring body 1 and is fastened to the corresponding two fixing plates 3 by bolts and nuts. The arc-shaped connecting plates 5 of the two connecting rods 2 cooperate with each other and are fastened to each other by two sets of bolts and nuts. The distance between the two fixing plates 3 on the same side is the same as the thickness of the straight connecting plate 4 to ensure the stability of the straight connecting plate 4 after it is inserted between the two fixing plates 3 on the same side. The fixing plates 3 are provided with a first connecting hole 6, and the straight connecting plate 4 is provided with a second connecting hole 7. The second connecting hole 7 is connected to the first connecting hole 6 by bolts, thereby realizing the connection and disassembly of the straight connecting plate 4 and the fixing plate 3. The arc-shaped connecting plate 5 has two third connecting holes 8. The third connecting holes 8 of the two connecting rods 2 correspond one-to-one and are connected by bolts to realize the connection and separation of the two connecting rods 2 at one end of the arc-shaped connecting plate 5, thereby realizing the connection and disassembly of the two connecting rods 2 to the high-voltage core rod of the insulator through the arc-shaped connecting plate 5.

[0015] Installation method and operating principle: First, straight connecting plates 4 and arc-shaped connecting plates 5 are pressed at both ends of the connecting rod 2 using a molding die. Then, a second connecting hole 7 is made in the straight connecting plate 4 using a drilling device, and two third connecting holes 8 are made in the arc-shaped connecting plate 5. Next, the connecting rod 2 is bent using a bending device. Subsequently, the four fixing plates 3 with the first connecting holes 6 are welded in pairs to the upper surfaces of both sides of the ring body 1, and the distance between the two fixing plates 3 on the same side is matched with the thickness of the straight connecting plate 4. During assembly, the straight connecting plate 4 of the connecting rod is inserted between the two fixing plates 3 on the same side. After aligning the holes, bolts and nuts are used to fasten the connecting plate to the corresponding two fixing plates 3. The two arc-shaped connecting plates 5 are then fitted with the high-voltage core rod, and bolts and nuts are used to fasten the arc-shaped connecting plates 5 of the two connecting rods 2 to complete the connection with the high-voltage core rod of the insulator. This utility model has a reasonable structure. Two fixing plates 3 are provided on each side of the ring body 1, and a gap is left between the two fixing plates 3 on the same side to allow for insertion and cooperation with the straight connecting plate 4 of the connecting rod 2. At the same time, the straight connecting plate 4 is fastened between the corresponding two fixing plates 3 using bolts and nuts. This connection method greatly improves the stability of the connection between the connecting rod 2 and the ring body 1.
