摘要
Zn O电源SPD自安装进入电网运行开始,其所面对的电磁环境是复杂多变的,所承受的电应力种类繁多。本文根据ZnO电源SPD在电涌抑制状态下所承受的过电应力的情况,详细分析和归纳总结了影响电源SPD寿命长短的主要因子,以期指导ZnO电源SPD设计、施工和检测验收等工程实践工作。
When ZnO power SPD is installed into the power grid for operation, the electromagnetic environment is very complex, the kind of electrical stress is various. According to the case of excessive electrical stress in the state of surge suppression of ZnO power SPD,analyzes and summarizes the main factors affecting the service life of power supply SPD in detail, so as to guide the ZnO power SPD length design, construction and acceptance test of engineering practice.
