As an important device in the power system, the arrester's main function is to prevent lightning overvoltage from invading power equipment. As an important part of the arrester, the design, material and manufacturing process of the wound core have an important impact on the stability of the arrester's protective effect.
The main function of the wound core in the arrester is to enhance the electromagnetic performance of the arrester, so as to more effectively absorb and disperse the overvoltage generated by the lightning impulse. Compared with the traditional laminated core, the wound core has lower loss and higher efficiency, which enables the arrester to respond more quickly under lightning impulse and limit the overvoltage to the range that the equipment can withstand.
The material selection of the wound core is also crucial. High-quality wound core materials have higher magnetic permeability and lower hysteresis loss, which helps to improve the dynamic response speed and energy absorption capacity of the arrester. At the same time, the manufacturing process of the wound core also directly affects its performance. Precise winding process and tight interlayer bonding can reduce eddy current loss and improve the thermal stability and long-term operation reliability of the arrester.
In the actual application of lightning arresters, the stability and durability of the wound core are crucial to the stability of the protection effect. If the wound core is defective or aged, the arrester may not be able to act in time or not act quickly enough under the lightning strike, thus causing the power equipment to be damaged by lightning. In addition, overheating or deformation of the wound core may also cause the arrester to deteriorate in performance or even fail.
In order to improve the stability of the protection effect of the lightning arrester wound core, the following measures can be taken: First, select high-quality wound core materials and manufacturing processes to ensure that the wound core has excellent electromagnetic properties and durability; second, regularly inspect and maintain the arrester to promptly discover and deal with defects or aging problems in the wound core; third, select appropriate arrester models and specifications according to the specific needs of the power system to ensure that the arrester can fully play its protective role under lightning strikes.
The lightning arrester wound core has an important impact on the stability of the protection effect. By optimizing the design, material and manufacturing process of the wound core, and strengthening the inspection and maintenance of the arrester, the stability of the arrester's protection effect can be significantly improved, providing a strong guarantee for the safe operation of the power system.
