随着经济的快速发展,为了满足不同用户在高科技通信业务方面的要求,智能楼宇中安装了大量先进的电信传输系统、楼宇自控系统,人们在享受高科技所带来的快捷、便利的同时,也认识到,由于这些敏感电子设备的工作电压不断降低,其数量和规模的不断扩大,因而受到过电压(由于内部强电设备的操作及投切而产生的浪涌电压)
With the rapid economic development, a large number of advanced telecom transmission systems and building automation systems have been installed in intelligent buildings in order to meet the requirements of different users in high-tech communications services. People enjoy the fast and convenient high-tech , But also realized that due to the continuous decrease of working voltage of these sensitive electronic equipments and their increasing number and scale, they are overvoltage (surge voltage due to the operation and switching of internal strong electric equipment)
