The widespread usage of electricity promoted to defend the development of thunder product and be a high pressure power grid to provide motive and illuminate for the thousand 10000, thunder and lightning also a great deal of bane high pressure lose to change to give or get an electric shock an equipments.The high pressure line installs Gao, be apart from long, cross geography complications, is strike by lightning easily medium.The protection scope shortage of the lightning rod with protect up to thousand power lines, so avoid thunder line as to protect high pressure line of new connect a Shan machine to emerge with the tide of the times.After the high pressure line acquire a protection, the hair linked with high pressure line, go together with electricity equipments to be still conduct electricity to press damage, people discover this is because"respond thunder" is play tricks.(Respond the thunder is to respond the metals conductor of neighborhood because of keeping shot thunder to turn on electricity in, respond the thunder can pass 2 kinds to differently respond way incursion conductor, one is an electrostatic induction:When the electric charge in thunder cloud accumulates to ga

当人们知道,雷电是一种电力的现象后,向崇拜的雷电与恐惧感逐渐消失,并开始与品味,科学来自新观察自然现象,这魔术,希望使使用或控制雷电活动,以造福人类.超过二百年以来几乎富兰克林为首的小康就技术开始挑战对雷电,他发明的避雷针可能被视为向在最早现阶段维护雷声大的产品和产品名称,今天这几乎由全体人民已知道.事实上,富兰克林发明避雷针是认为金属避雷针的角度谈谈对电力的功能,可合成电荷在积雨云,使积雨云和电场的地球一样低的水平,不能突破的空气中,避免罢工,因此,闪电发生时,当时的避雷针,必须要求尖利.但是事后研究阐述证明:闪电控制棒是发生不可避免的打雷的,因为它可以证明雷声大,是因为建筑物较高,是矗立在签署的避雷针改变了大气电场,使积雨云的一定范围内始终把对电力对闪电棒,也就是说,避雷针只是比它周围其他物体更容易连接山雷电,避雷针是罢工的闪电,但是它可以对其他物体加以保护,这是捍卫建筑物的一种方式,避雷针防雷更加深刻的研究表示,连接避雷针山的功能,几乎有一些建筑物不是很高,但没有形状,可说是避雷针不一定是雷声大,技术的境界,将会知道一起像现在这种类型的防雷装置。广泛使用的电力,促进了发展防雷产品和一个高压电网提供的可以照亮千万人类电动机,雷电也是大的高的压力祸根,失去了改革,就相当于给予或得到一个电动休克.
一、建筑物的防雷分类
对规范中明确指出的防雷建筑物类别,可直接套用。规范中对有些建筑物仅指出大于预计雷击次数XX次/每年,而归属二类或三类防雷建筑物。对于这些规定,在设计中仅凭直观感觉和经验,就不能明确确定其建筑物所属防雷类别,使应做二类防雷误做成三类,应做三类防雷而没做,结果是对建成的建筑物造成一定的隐患。这就有必要据当地的年平均雷暴日及建筑物所在地的地理、地质土壤、
