Composite low-voltage arrester
An overview
Metal oxide arrester is an internationally advanced high-tech product of the 1990s. It uses an oxygen-zinc resistor with excellent nonlinear volt-ampere characteristics, so the protection characteristics of the arrester under slope lightning wave operation are greatly improved compared to traditional silicon carbide arresters. In particular, zinc oxide resistors have the advantages of good slope response characteristics, no delay in operation at steep voltage slopes, low residual voltage, and no discharge dispersion. This overcomes the inherent shortcomings of silicon carbide arresters such as high steep slope discharge voltage caused by steep slope discharge delay, high operating wave discharge voltage due to large operating wave discharge dispersion, greatly improves the protection margin under steep slope operating waves, and improves the insulation coordination. On the one hand, the protection margin of steep slope lightning wave operating waves can be nearly consistent, thereby providing the best protection for power equipment and improving the reliability of protection. Zinc oxide arresters have the ability to absorb both lightning overvoltage operating overvoltage and power frequency transient overvoltage.
The composite jacket metal zinc oxide arrester is a high-tech product of the international era. Made of integral silicone rubber molding, it has good sealing performance, excellent explosion-proof performance, is resistant to dirt, requires no cleaning, and can reduce the occurrence of wet flashes in foggy weather. It is resistant to electrical corrosion and aging. It is small in size, light in weight, collision-resistant, and easy to install and maintain. It is an updated product of the porcelain sleeve arrester.
