弱电设备防雷电危害与抗干扰研究

随着我国国民经济的快速发展，建筑物内智能化弱电设备的使用越来越广泛，虽然建筑物内设备在建筑物避雷针的保护下一般可避免直接遭受雷击，但“感应雷”在闭路电视监控、网络、电话、卫星接收天线、有线电视等与外部电线上仍可以产生较高的感应电压，该感应电压只是短暂的一瞬间，但其峰值足够使各种弱电设备受到损害或者严重干扰而失去正常性能...

Elv Equipment Electrical Hazards And Lightning Anti-jamming Research And Application

Along With the rapid development of national economy,building intelligent electrical equipment,more building equipment under the protection of the lightning rod can be avoided direct suffered by lightning,induction lightning on closed-circuit television monitoring,network,telephone,satellite antenna,cable TV and external electric wires can still produce higher induced voltage.It induced voltage only a short moment,its peak enough to make various electrical equipment damage or serious interference and lose n...
