广东大亚湾核电站属多雷发地区,雨季雷电次数过百,为避免因雷击造成计算机控制及网络通信设施损坏,必须采取防雷措施。雷电侵害有直击雷侵害和感应雷侵害。地电压反击和雷电波侵入是机房设备损坏的主要原因,机房防雷系统应防止地电压反击和雷电波侵入。为避免地电压反击造成的损失,可使用交流过压保护器和直流浪涌抑制器。采用“3×1+1”防雷器更适合机房电源系统。
Guangdong Daya Bay Nuclear Power Station belongs to the more thunder and fat areas, rainy thunder and lightning over the number of hundred, in order to avoid computer damage caused by lightning and network communication facilities damage, must take lightning protection measures. Thunder and lightning have a direct impact on the thunder and lightning damage. Ground voltage counterattack and lightning intrusion is the main reason for equipment room damage, room lightning protection system should prevent the ground voltage and lightning intrusion. To avoid losses caused by ground-voltage counterattacks, use AC overvoltage protectors and DC surge suppressors. Using “3 × 1 +1” lightning protection device is more suitable for the engine room power system.
