摘要
在电力系统中使用的10 kV避雷器数量巨大,其质量对10 kV架空线路防雷水平至关重要。通过对10 kV复合外套金属氧化物避雷器进行整只4/10μs、65 kA大电流冲击耐受试验,分析结果得出:10 kV复合外套避雷器生产工艺对其大电流冲击耐受能力有重要影响,在非电阻片因素下,通过改进生产工艺可提高大电流冲击耐受能力。
A huge amount of 10 kV arresters are used in the power system. The quality of the arrester is important to the lightning protection level of 10 kV lines. Through the 4/10 μs,65 kA high- current impulse withstand test on the 10 kV polymer housed MOA, the analysis results show that： high current impulse withstand capability of the 10 kV polymer housed surge arresters is impacted significantly by its production process. In case of no resistor factor, the high-current impulses withstand capability can be improved by improving the production process.
