From the principle point of view, corona discharge is a partial discharge phenomenon caused by the ionization of air under a high-voltage electric field. It is commonly found on the tip or irregular surface of high-voltage power transmission and transformation equipment, power capacitors, transformers and other equipment. This discharge process will be accompanied by the release of a variety of harmful substances. For example, ozone and nitrogen oxides, when the concentration of ozone is too high, it can irritate the mucous membranes of the human respiratory tract, causing cough, chest tightness and other discomfort. Long-term exposure may also damage lung function. Nitrogen oxides will combine with water vapor in the air to form acidic substances, which not only corrode equipment, but also enter the human body through breathing, increasing the risk of respiratory diseases. Moreover, corona discharge will produce high-frequency electromagnetic radiation. Although the intensity is usually lower than the strong radiation standard, long-term close contact may still interfere with the human nervous system, leading to fatigue, inattention and other problems, especially for substation duty personnel, equipment maintenance engineers and other high-frequency contact people have a significant impact. In addition, the weak ultraviolet radiation and local high temperature generated during the discharge process may also cause chronic damage to the skin, but these potential hazards are often easily ignored by the purchaser, and ultimately lead to health and safety risks in project operations.
For B-terminal buyers, the harm of corona discharge may also trigger a more complex chain reaction. In markets such as Europe and the United States, regulations such as the Occupational Safety and Health Act and the European Union's Workplace Health and Safety Directive have strict limits on the concentration of harmful gases and radiation intensity in the working environment. If the purchased power equipment is not equipped with an effective corona ring coil, the corona discharge in operation exceeds the standard, and the enterprise not only needs to bear the additional cost of equipment rectification, but may also face fines and shutdown penalties from regulatory authorities. At the same time, labor disputes and project delays caused by employee health problems can also damage the company's brand reputation and customer trust. This kind of hidden loss usually far exceeds the initial investment in corona ring coil procurement.
Facing this problem, choosing a professional corona ring coil has become the focus of procurement decision-making. Our corona ring coil is designed for the core hazards of corona discharge and can provide full-scene protection for power equipment. Corona ring coil adopts a composite process of high-strength alloy materials and special insulating coatings. By optimizing the radius of curvature of the ring structure, it can effectively reduce the electric field strength on the surface of the equipment and suppress the generation of corona discharge from the source. Corona ring coil allows ozone and nitrogen oxide emissions to fully meet international standard limits.
Although the hazards of corona discharge are hidden, they can be completely prevented and controlled through scientific protective methods. For B-side buyers pursuing long-term project value, choosing a reliable corona ring coil is not only responsible for the health of employees, but also an important measure to avoid compliance risks and reduce operating costs.
