The working logic of corona ring coil is to achieve precise suppression of corona discharge through electric field optimization. Corona ring coil is usually installed at the end of high-voltage equipment or at the conductor with a smaller radius of curvature. These areas are high-incidence areas of corona discharge because of the concentration of electric fields. Corona ring coil adopts a special structure design of arc or ring shape. The smooth arc surface can effectively disperse the electric field strength on the surface of the conductor, flatten the original highly concentrated electric field and distribute it evenly on the surface of the ring body, so that the local electric field strength is always lower than the breakdown field strength of the air, and prevent the generation of corona discharge from the root cause.
In more depth, the working performance of high-quality corona ring coil depends on material selection and process accuracy. Taking our products as an example, the ring body is made of high-strength alloy materials. This kind of material not only has good electrical conductivity, but can quickly conduct electric charge to maintain the balance of the electric field. It also has strong corrosion resistance and aging resistance. It can operate stably for a long time in harsh outdoor environments such as high humidity, high pollution, and strong ultraviolet rays to prevent unbalanced electric field distribution due to material deterioration. At the same time, our corona ring coil has undergone CNC precision machining, and the surface roughness of the ring body is very low, without any burrs or bumps. This is because any small surface defect may become a new electric field concentration point, so our process standards avoid this risk from the source, so that every part of the ring body can play the role of a uniform electric field.
In practical application scenarios, the value of corona ring coil's work has been widely verified by the global power industry. After installation on the insulator string of the high-voltage transmission line, the corona loss of the equipment can be reduced by more than 60%, saving a lot of electrical energy for the power grid every year. Used at the end of the high-voltage casing of the substation, the insulating layer can be effectively avoided from cracking due to corona corrosion, and the service life of the equipment can be extended by 5 to 8 years. Even at high altitudes, our corona ring coil can stably control the electric field strength through a customized ring diameter and wall thickness design, allowing the equipment to operate without corona.
