摘要
通过对低压配电结构用电涌保护器(SPD)的后备装置的分类配合测试,进行实验信息的比较,研究熔断器与断路器对UP(电压保护水平)的干扰,以及各种不同流经容量电涌保护器后备保护设备的运行状况,以阐述在实际工作中使用时,选用后备保护设备的原因。
This paper compares the experimental information through the classification matching test of back-up device of SPD in low-voltage power distribution structure to study the interference of fuse and circuit breaker to UP(voltage protection level)and the differences Flow through the capacity of the surge protection backup protection equipment operating conditions to illustrate the use in the actual work,the use of backup protection equipment reasons.
