The corona effect is a common physical phenomenon in the operation of high-voltage power equipment. It refers to the discharge phenomenon caused by local ionization of the medium when the electric field strength on the surface of the conductor exceeds the breakdown field strength of the surrounding medium. This kind of discharge is usually accompanied by low light, sizzling sound, and the production of gases such as ozone. A light blue halo can be clearly observed at night or in the dark. The generation of corona effect is closely related to the distribution of electric field on the surface of the conductor. In high-voltage equipment, the smaller the radius of curvature of the conductor surface, the more concentrated the electric field intensity, and the easier it is to cause corona. Corona will not only cause power loss, but also produce electromagnetic interference, noise pollution and corrosive gases, which will adversely affect the insulation of equipment and the surrounding environment.
Vibration damper corona ring is an important part of suppressing the corona effect. The principle is to reduce the electric field strength on the surface of the conductor by optimizing the electric field distribution, so as to prevent the local field strength from exceeding the dielectric breakdown threshold. The purpose. Vibration damper corona ring usually adopts a metal ring structure and is installed at the end of high-voltage equipment or in areas prone to corona. When the high-voltage equipment is charged, the vibration damper corona ring can disperse the electric field that was originally concentrated in the sharp part to the surface of the ring, making the electric field distribution more uniform.
Vibration damper corona ring is widely used in power systems, including transmission lines, substation equipment, high-voltage test devices and other fields. In transmission lines, the vibration damper corona ring is installed at both ends of the insulator string, which can effectively suppress the corona discharge of the wire joints and the ends of the insulators, and reduce line losses and electromagnetic interference. In substations, vibration damper corona ring needs to be installed at the ends of high-voltage equipment such as transformer bushings and lightning arrester, so that the equipment can operate stably at high voltages.
For the vibration damper corona ring to continue to function, regular maintenance inspections are required. The specific inspection steps include regularly cleaning up the dust, oil and oxide layers on the surface of the ring to prevent the electric field distortion caused by the surface dirt from causing a secondary corona. And check whether the ring is deformed, cracked or loose. If it is found to be damaged, it needs to be replaced in time to prevent the electric field distribution from being affected by structural defects.
In short, vibration damper corona ring can effectively solve the corona problem of high-voltage equipment through scientific structural design and reasonable application, and is an important component to ensure the safe and efficient operation of the power system. In practical applications, the selection and maintenance work can be done in combination with specific scenarios, so that the vibration damper corona ring can give full play to the role of suppressing corona.
