暂时过电压威胁SPD安全使用的分析
Analysis about SPD’ Safe Use Under TOV
【摘要】 分析了低压系统暂时过电压情况以及限压型电涌保护器在暂时过电压情况下的性能表现。介绍了现行国标对电涌保护器的TOV考核要求,以及IEC标准的发展情况。指出电涌保护器应当进行暂时过电压试验考核。
【Abstract】 The condition of temporary over-voltages in low voltage system and the performance of the voltage limiting type SPD under the TOV were analyzed.The TOV test request of SPD in current national standard and development of IEC standard were introduced.It was indicated that the TOV tests were applicable to all the SPD.
