From the essence of physics, the high-voltage corona effect refers to the partial discharge phenomenon caused by the ionization of air molecules when the strength of the local electric field exceeds the breakdown field strength of air on the surface of a high-voltage transmission line or power equipment. This kind of discharge does not occur in a complete breakdown between the electrodes, but is concentrated in the area with the highest electric field strength on the surface of the conductor. Visually, the corona effect may be manifested as a faint blue-purple halo around the conductor at night. Audibly, it will be accompanied by a continuous buzzing sound or buzzing sound. At the level of electrical performance, the impact of the corona effect is far more complicated than these intuitive phenomena.
The harm of the corona effect to the high-voltage power grid is mainly reflected in three angles, each of which is directly related to the operating costs and safety risks of power companies. The most important thing is the problem of electrical energy loss. During the corona discharge process, ionized air molecules continue to collide with neutral molecules, which will convert part of the electrical energy into heat, light and sound energy and consume it. This is a cost that cannot be ignored for power grid operators who pursue maximizing energy efficiency.
Moreover, the corona effect will produce serious electromagnetic interference and environmental noise. During the discharge process, ionized air molecules will radiate wide-band electromagnetic waves. These electromagnetic waves will interfere with surrounding signals or equipment, which may cause equipment to malfunction and affect the scheduling and safe operation of the power grid. At the same time, the audible noise generated by corona discharge will spread with the extension of the transmission line, and may exceed the limits stipulated by environmental protection standards in residential areas and near office areas, causing complaints from surrounding people and bringing environmental compliance pressure to power companies.
In addition, the long-term corona effect will accelerate the aging and corrosion of power equipment, laying safety risks. During corona discharge, strong oxidizing gases such as ozone and nitrogen oxides will be produced. These gases will combine with moisture in the air to form acidic substances, which will cause corrosion to the metal coating on the surface of the wire, the umbrella skirt material of the insulator, and the joints of the metal fittings. These problems will not only shorten the service life of the equipment, but may also cause sudden failures such as line tripping and power outages, which will bring high maintenance costs and safety risks to the operation and maintenance of the power grid.
In the face of the various hazards caused by the high-voltage corona effect, choosing a reliable vibration damper corona ring is an inevitable choice for power grid operators. The vibration damper corona ring we independently developed is an efficient response product for customers around the world based on our understanding of the corona effect. This vibration damper corona ring is made of high-strength alloy material, the surface is precision polished, and covered with a special weather-resistant and anticorrosive coating. Vibration damper corona ring can not only adapt to extreme temperature ranges and coastal high salt spray environments, but also through a unique arc structure design, the concentrated electric field at key nodes of the transmission line is evenly dispersed, and the local electric field strength is stably controlled below the air breakdown field strength. Vibration damper corona ring can suppress the generation of corona discharge from the source.
