随着社会经济的不断发展，大型全电子衡器已被各工矿企事业广泛使用。大型全电子衡器往往被安置在户外，易遭到雷击等非人为因素的损害，极易使称重传感器等电子设备损坏，使电子衡器不能正常工作。故大型全电子衡器（轨道衡、汽车衡等）的接地系统就显得格外重要，它能有效地 With the continuous development of social economy, large-scale all-electronic weighing instrument has been widely used by various industrial and mining enterprises. Large electronic scales are often placed outdoors, vulnerable to lightning and other non-human factors damage, easy to make weighing sensors and other electronic equipment damage, so that electronic weighing can not work properly. Therefore, it is especially important that the grounding system of a large all-electronic scale (track scale, truck scale, etc.)
