摘要
针对变电站开关动作时产生的瞬态电磁环境改变对线路及电气设备的影响,采用通过实验室试验,电磁脉冲模拟器(EM P)模拟开关操作时的瞬态电磁环境,分析传输线及电气设备受到电磁干扰的情况,提出对变电站的电气设备的抗扰度实验应增加瞬态电场测试,以及二次电缆屏蔽层应双端接地并进一步采取相应防护措施等建议。
Transient electromagnetic environment during switching operation has been simulated by indoor EMP equipment based on transient electromagnetic environment change and its affect on lines and electric facilities.Disturbed situation of transmission line and electric facilities are analysed,and suggestions on adding immunity test and secondary cable shielding layer grounding are proposed for further protection.
