                    当雷电发生在距离建筑物或构建物较近的地方,通过避雷针将可能击中于建筑物本体的雷电吸引并通过避雷针泄放入大地,引雷进入大地的过程,避雷针必须和树木有绝缘层隔离,引下线要用绝缘管等绝缘物质包裹着,防止雷电流进入树木,对树木产生破坏。

                    技术参数:

                    提前放电避雷针,JLT-A6000工作原理:

                    LDY-A6000  避雷针主要由激发器从自然界的电场中吸收并储存能量。反射器及避雷器针尖与大地有良好的电气连接,处于等电位状态。
                    所以通常情况下,激发器与反射器之间有电场强度,每当雷闪发生前,电场强度会迅速增大,激发器与反射器之间的电位差大致相当于
                    雷云与大地之间的电位,他们之间的电压降迅速增加会造成尖端打火,并使尖端周围的空气离子化,形成尖端放电现象。避雷针的中央
                    收集杆和激发器之间的电场迅速增加,造成尖端产生的空气离子化,并在极短的时间内放电,因大量离子的存在,从而使大自然的Corona
                    效应减低,产生一预期上行的放电通道,可迅速、安全地将雷电截击及全泄放到大地。
