介绍铁路货车超偏载检测装置综合防雷系统的方案设计、防雷原理及技术方法,分析总结了系统的主要特点和使用效果。与既有的采取局部范围、单一元件进行防护的措施相比,采用综合的三级防护和二次防护及屏蔽、接地网络建设,把所有的信号设备看成一个整体系统,将局部、单一的防范措施提升到系统防护、整体防护高度,使各级防雷器件互相协调工作,实现多级配合,层层泄流,效率更高,更能全面防护雷电和电磁脉冲的干扰,具有稳定和全面保护相结合的特点。
This paper introduces the scheme design, lightning protection principle and technical methods of integrated lightning protection system for overloading and overloading of railway freight cars, and analyzes and summarizes the main features and the application results of the system. Compared with the existing measures of adopting partial range and single component for protection, the integrated three-stage protection, secondary protection, shielding and grounding network construction are adopted, and all the signal devices are regarded as a whole system. Local and single Prevention measures to upgrade to the system protection, the overall height of protection, so that all levels of lightning protection devices work together to achieve multi-level coordination, layers of discharge, more efficient and more comprehensive protection of lightning and electromagnetic pulse interference, with a stable and comprehensive The combination of protection features.
