Corona ring coil is an annular or arc-shaped part made of metal. It is a common auxiliary device installed at the end of high-voltage equipment or in parts with large curvature. In order to adjust the distribution of the surrounding electric field, the shape of corona ring coil is a smooth curved surface without edges, corners and tips.
The role of corona ring coil:
When the high-voltage equipment is running, if the electric field strength on the surface is uneven, the local electric field strength will be too high, which will penetrate the surrounding air and produce corona discharge. This kind of discharge will cause problems such as consuming electrical energy, reducing system efficiency, eroding equipment surfaces, shortening service life, and interfering with communications and measuring equipment. The role of corona ring coil is to disperse the electric field originally concentrated at the tip to the annular surface by increasing the radius of curvature of the electrode, so that the electric field strength is evenly distributed, preventing the local electric field strength from exceeding the breakdown threshold of the air, and suppressing the occurrence of corona discharge.
Advantages of corona ring coil:
1. The use of corona ring coil to suppress corona discharge can reduce the corrosion and aging of the surface of the equipment, extend the service life of components such as insulators or cable terminals, and ensure the safety of the equipment. At the same time, it can reduce maintenance costs and the possibility of failure.
2. The use of anti-corona ring can reduce the energy loss of corona discharge and improve the efficiency of power transmission.
3. The use of anti-corona ring can prevent electromagnetic interference caused by corona discharge, enable communication equipment and radar near the transmission line to work normally, and reduce the electromagnetic pollution of corona to the surrounding environment.
4. In humid, foggy, high altitude and other environments that are prone to corona, the effect of anti-corona ring is more obvious. For example, in high altitude areas, the air is thin, and the effect of preventing discharge is more effective.
In high-voltage power supply systems, the anti-corona ring is a device that suppresses corona discharge by optimizing the electric field distribution. Anti-corona ring can protect equipment, improve efficiency, and reduce environmental interference. It is an important auxiliary component to ensure the safe and stable operation of high-voltage power systems. Vilun Electric Co., Ltd. by optimizing the design and material selection of the anti-corona ring, the corona undulating voltage can be more than doubled, and the electrical performance of the optical cable can be enhanced to a certain extent. Anti-corona ring can reduce the swing of wires or optical cables under the action of wind, avoid wear or damage caused by long-term vibration, reduce the frequency of maintenance and repair, and thus extend the service life of the line.
