摘要
根据智能变电站合并单元在电快速瞬变脉冲群(EFT/B)试验中存在的问题,利用瞬态电压抑制器和铁氧体磁珠相结合的方式改进电源滤波电路、优化PCB板,同时采用看门狗技术、软件滤波等方法增强装置的抗干扰性能,使装置能满足EFT/B试验等级4的要求。
According to the problem of merging unit during the test of electrical fast transient, by taking advantage of transient voltage suppressor and ferrite beads to improve power filter circuit, optimizing the print circuit board, making use of watchdog and software filtering, the merging unit can meet the requirement of electrical fast transient of bank 4.
