介绍了光伏系统直流侧电涌保护器的过载特性试验方法和合格判据。使用直流电源对电涌保护器进行过载特性试验。试验结果表明，应准确选择电涌保护器的压敏电阻，流过电涌保护器电流才能使脱离器在规定时间内动作，以避免电涌保护器燃烧。
介紹瞭光伏繫統直流側電湧保護器的過載特性試驗方法和閤格判據。使用直流電源對電湧保護器進行過載特性試驗。試驗結果錶明，應準確選擇電湧保護器的壓敏電阻，流過電湧保護器電流纔能使脫離器在規定時間內動作，以避免電湧保護器燃燒。

This paper introduced the test method and pass criteria of overload behavior of surger protective device (SPD)which was used in the DC side of photovoltaic system.The overload behavior test was conducted with the DC source facility in the laboratory.The experimental results the piezoresistor should be selected accurately,so the current which flows through the SPD makes the disconnector action within the stipulated time,to avoid the SPD burning.
