Thesis: operation and maintenance of metal oxide surge arresters and application
ABSTRACT Lightning strike caused the accident about half of the total power system accident, a very large impact on the system, a serious impact on the safety and reliability of power supply, while the arrester is one of the protective equipment to ensure the safe operation of power systems, mainly for limit line came the lightning over-voltage or the operation due to internal over-voltage substation arresters essentially metal oxide surge arresters, metal oxide surge arresters with small size, light weight, good efficacy, convenient installation performance. Substation installation of surge arresters in the operation of most of the operation, but also a breakdown or other failure. From the metal zinc oxide arrester classification, characteristics, operation and maintenance of common fault analysis and maintenance tests described aspects of the metal zinc oxide arrester, on-site work to play a guidance and reference.
