有关华北风电集送系统中500 kV避雷器短时工频过电压试验的探讨
Short-Time Power Frequency Overvoltage Test of 500 kV Arrester in North China Centralized Wind Power Transmission System
摘要
Abstract
The performance of arrester to withstand short-time power frequency overvoltage affects the output capacity of wind power in North China.The author analyzes the characteristics of short-time pow-er frequency overvoltage of wind power gathering and transmission system in North China,and discusses the applicability of short-time overvoltage test procedures,the selection of test overvoltage multiples,the capacity of test equipment and other key issues related to test verification.Taking a 500 kV lightning ar-rester as an example,the short-time power frequency overvoltage test is conducted to verify the reliabili-ty of the lightning arrester,which provides an idea for the reliability verification method of lightning ar-rester in this system.关键词
