摘要
在低压配电系统和弱电系统防雷保护中大量采用了电涌保护器(SPD)。由于现有的冲击波形发生器多为实验室设备,重量大、不便携带,已安装使用的SPD大多未进行冲击检测。分析了现场检测SPD的必要性,并通过对小型直流高电压电源、小型组合波产生电路和小型冲击测量电路的研究,成功研制了新型便携式电涌保护器检测装置,总重量13 kg。该测试装置能方便、有效地测出现场使用SPD性能,确保SPD的运行可靠性。
Surge protective devices（SPDs） are widely used for lightning protection in low-voltage（LV） distribution system and weak current system.Due to most of the impulse wave generators are laboratory equipment which is heavy inconvenient to carry,these on-site SPDs haven＇t been tested by impulse wave.This paper analyses the necessity of field test in detail,and designs a new SPD test system by small direct-current high voltage generator,small combination wave generator and small impulse peak measurement system.The total weight of test device is merely 13 kg,it is illustrated that the portable test system can recognize the performance of on-site SPD conveniently and effectively which ensures the reliable operation of SPD.
