Description

Technical Field

[0001] This utility model relates to the field of corona rings, and in particular to a multi-layer protective anti-corona ring. Background Technology

[0002] A corona ring is a device or structure related to the corona phenomenon, which typically occurs in high-voltage electric fields. When the electric field strength exceeds the breakdown strength of air, the air is ionized, producing weak light and discharge phenomena. This phenomenon is called corona discharge. A corona ring is a device specifically designed to control or utilize this corona discharge. Corona rings are usually made of conductive materials and are shaped like a ring or circular structure. They are installed at appropriate locations on high-voltage equipment. Their main function is to locally enhance the electric field, causing corona discharge to concentrate on the ring structure, thereby preventing corona discharge from occurring in other unwanted areas. This effectively reduces the damage of corona discharge to equipment, extends the service life of the equipment, and reduces electromagnetic interference and noise.

[0003] Currently, corona rings are mostly installed at the ends of conductors in high-voltage transmission lines to reduce corona discharge, which is the phenomenon where the air around a conductor is ionized under high voltage, producing weak light and sound.

[0004] However, the aforementioned corona rings have certain defects in use. Since the corona rings rely on the conductive material itself to be directly exposed to the external environment, extreme weather conditions can cause the corona rings to loosen and become unstable, making them difficult to securely install on the conductive material. This reduces their protective effect and may even affect the safe operation of the transmission lines.

[0005] To address this issue, a multi-layered protective corona ring is proposed. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a multi-layer protective anti-corona ring.

[0007] This utility model is achieved using the following technical solution:

[0008] A multi-layered protective corona ring, comprising

[0009] A high-voltage bushing, wherein an insulating core is provided inside the high-voltage bushing;

[0010] A conductive rod, which passes through a high-voltage bushing and is fixedly connected inside an insulating core, and a fixing device is fixedly connected to the end of the conductive rod;

[0011] A fixing device, comprising an energy-absorbing ring, a wrapping ring, and grooves, wherein the energy-absorbing ring is fixedly connected inside the wrapping ring, and the inner wall of the fixing device is provided with multiple grooves;

[0012] A corona ring, wherein the corona ring is installed in multiple grooves by a fixing device;

[0013] A reinforcing ring is fixedly connected to the outer wall of the fixing device. One end of the reinforcing ring is provided with an upper clamp and the other end is provided with a lower clamp. The upper clamp and the lower clamp are provided with two through holes. A positioning screw is installed in each of the two through holes. The through holes are threaded holes and the positioning screws are threaded into the through holes.

[0014] As a preferred embodiment of this utility model, an insulating locking ring is installed at one end of the conductive rod, and the insulating locking ring is located on one side of the fixing device. Two insulating brackets are fixedly connected to the insulating locking ring, and each of the two insulating brackets is equipped with a buckle. The buckle is fixedly installed at the end of the corona ring.

[0015] As a preferred embodiment of this utility model, the outer wall of the high-pressure bushing is provided with a ceramic ring, and there are multiple ceramic rings.

[0016] In a preferred embodiment of this utility model, a nut is fixedly connected to the end of the positioning screw, and the positioning screw fixes the upper clamp and the lower clamp through the through hole.

[0017] As a preferred embodiment of this utility model, a bushing flange is installed on the side of the high-pressure bushing away from the fixed device.

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] 1. By installing a fixing device at the end of the conductive rod, the energy-absorbing ring inside the fixing device is tightly connected to the conductive rod. The energy-absorbing ring is made of conductive material, and multiple grooves are provided on the inner wall of the fixing device. The corona ring is fixed to the energy-absorbing ring through the grooves. The installation of the corona ring inside the fixing device effectively improves the stability of the corona ring, avoids loosening caused by extreme weather, reduces maintenance costs, and ensures the stability and safety of the transmission line.

[0020] 2. A reinforcing ring is also installed on the outer wall of the fixing device. One end of the reinforcing ring is provided with an upper clamp and the other end is provided with a lower clamp. The upper clamp and the lower clamp are provided with two through holes. Positioning screws are installed in both through holes. The upper clamp and the lower clamp are firmly locked by the threaded assembly of the positioning screws, which enhances the stability of the fixing device and completely fixes the corona ring during use.

[0021] 3. An insulating locking ring is installed at one end of the conductive rod. The insulating locking ring is located on one side of the fixing device. Two insulating brackets are fixedly connected to the insulating locking ring. Each of the two insulating brackets is equipped with a locking buckle. The locking buckle is tightly connected to the end of the corona ring. The locking buckle is installed at the end of the corona ring to fix the end of the corona ring as well. This ensures the overall stability of the corona ring under extreme weather conditions, reduces the risk of equipment damage caused by external factors such as wind, and extends the service life of the equipment.
