自然界雷电的突然发生对铁路信号设施危害极大,每年由于雷害破坏铁路信号设备的发生。不仅给经济上造成很大损失,特别是给铁路的安全运输带来极坏影响。为此,研究雷害采取相应的防雷措施,多年来是铁路职工所关心的研究课题。一九七九年哈尔滨铁路局科研所和电务处防雷小组的同志们在有关单位的大力支持下,建成了初具规模的防雷试验室。目前自行设计安装运用的四路球隙冲击电流发生器,不但球
The sudden occurrence of thunder and lightning in nature is extremely harmful to the railway signal facilities. Every year, the occurrence of railroad signal equipment is disrupted by thunder and lightning. This not only causes great economic losses but also has a very bad influence on the safe transport of the railway. To this end, the study of mine damage to take the appropriate lightning protection measures over the years is the railway workers are concerned about the research topic. In 1979, comrades from the research institutes of Harbin Railway Bureau and the Lightning Protection Group of the Electrical Services Department completed the first-phase lightning protection laboratories under the strong support of the relevant units. At present, the design, installation and use of four ball gap impact current generator, not only the ball
