电子地磅易遭遇雷击的原因

发布日期:2018-06-04 作者: 点击:

每逢雷雨季节,我们地磅厂商就开始变得忙碌起来,并不是忙着生产,而是是忙着维修。由于地磅客户防范意识不够,致使地磅遭受雷击,从而造成一定的损失。下面我们就电子地磅易遭遇雷击的原因进行分析:

During the storm season, we loadometer manufacturers began to get busy, not busy with production, but is busy repairing. Because loadometer customer awareness is not enough, resulting in loadometer lightning, resulting in a loss. We have the following electronic loadometer prone to lightning causes analysis:


静电感应:地磅称体为较大的金属物体,在雷云出现到雷击(主放电)以前,在雷电静电感应作用下,称体感应产生大量静电荷,当雷击发生时,云电荷通过闪击与地面的异电荷迅速中和,由于地磅接地电阻过大,造成大量静电荷无法在短时内向大地泄放,就形成了局部感应高电压,并对与称体接触不良的金属器件(称重传感器)发生闪击。形成强烈放电现象。闪击造成称重传感器带上高电位并沿数据总线侵入终端电子设备(显示仪表等)。

Electrostatic induction: loadometer said body for metal objects appear larger, lightning in clouds (the main discharge) before the lightning electrostatic induction effect, said body induced large static charges, when lightning occurs, the cloud charge through the different charge blitz with the ground and quickly, because loadometer grounding resistance is too large, resulting in large static charges in a short period of time within the earth cannot discharge, forming local induction high voltage, and the device with metal poor contact body (called weighing sensor) occurred blitz. A strong discharge is formed. This caused the weighing sensor with high potential and the data bus terminal into electronic equipment (display instrument).


电磁感应:当雷击落点在地磅附近时,由于雷电流有极大峰值和陡度,即闪电通道中电流随时间发生变化,在整个地磅系统周围空间形成强大的瞬变电磁场,在通道附近的导电物体产生一系列的电磁脉冲耦合过电压和涡电流。电子地磅称重传感器,接线盒,显示仪表等由于回路布置较复杂,导致雷电磁脉冲在回路中感应出瞬态高电位和过电流并危及与回路连接的设备。

Electromagnetic induction: when lightning strikes near the placement in the weighbridge due to lightning current, great peak current and steepness of lightning channel changes over time, the formation of a strong transient electromagnetic field in the space around the weighbridge system, produce electromagnetic pulse coupling overvoltage and eddy current in a series of conductive objects near the channel. Electronic loadometer weighing sensor, junction box, display instrument as the loop layout is more complex, resulting in lightning magnetism pulse in the loop induced transient high potential and current and endanger and loop connecting equipment.


雷电波侵入:由于磅房的供电线路、信号线采用架空敷设,供电线路、信号线在架空传输过程中遭受直接雷击或雷电静电感应、电磁感应作用,雷电流以脉冲波形式沿架空电线、信号线侵入(通常为几千伏~几百千伏),对磅房各类电子设备如地磅仪表等造成严重损毁。

Lightning wave intrusion: because the power supply line, the signal line housing pounds by overhead laying, power lines, signal lines from lightning or lightning electrostatic induction, electromagnetic induction in the transmission process, the lightning current in pulse wave forms along the overhead lines, signal lines invasion (usually several thousand volts to hundreds of volts), cause serious damage of various types of electronic equipment such as housing pounds loadometer instrument etc..
