电子衡器在露天工作时，遇到雷雨天气，受到雷击，会对衡器造成很大的破坏。雷电是一种常见的自然现象，而有些电子衡器必须在露天的环境下工作，面对这种情况，电子衡器如何防雷击也就显得很重要，按现代防雷技术的要求，建立“综合防护、系统防护、逐级限压”的全面防护的感念，下面就是设计方案：
1. 对传感器、二次仪表等电子衡器整体的各个部分，作特殊的等电位防雷保护
2. 切断传感器弹性体与秤台的电气通道，另外提供电流的泄放通道
3. 供电系统做多级防雷保护
4. 在秤台周围构建包括秤台基础在内的防雷接地网，整个系统在秤台附近单接地
5. 安装雷电记录仪，对电子衡器防雷系统作实时检测
本系统采取了“防护、综合治理、层层设防”的设计方法，所以它具有规范性、可靠性和*性。

How to design electron weighing apparatus and lightning system
Electron weighing apparatus in the work, meet the thunderstorm weather, by lightning, weighing apparatus caused great destruction. Lightning is a common natural phenomenon, and some electron weighing apparatus must be in the open air conditions, face this kind of situation, electron weighing apparatus how to prevent lightning also appears very important, according to the requirements of the modern lightning protection technology, the establishment of a "comprehensive protection, system protection, limited pressure level" of the comprehensive protection honored, below is design plan:
1. To sensors, second instrument and other electronic instruments each part of the whole, the special potential lightning protection
2. Cut off the scales and a sensor elastomer electrical channel, also provide current the return channel
3. The power supply system do multilevel lightning protection
4. In scale sets including scale construction around Taiwan foundation of substationgrounding grip, lightning, the whole system in scale stations single grounded
5. Installation lightning recorder, lightning protection system of electron weighing apparatus for real-time detection
This system adopted a "comprehensive protection, comprehensive management, trenches" design methods, so it is standardization, reliability and advanced.
