摘要
在宣钢二棒电气调试阶段,因传动接地施工的不完善,导致在调试西门子S120交流传动装置时频繁出现故障,典型如编码器速度跳变等,造成主传动调试周期拖延,进而影响整个调试工期。通过对原接地方案以及现场接地工作实际情况的分析,分别针对接地干线、主回路电缆、编码器控制电缆及传动装置进行了接地改进,最终使得调试工作顺利实施。
Xuanhua iron and steel corporation second bar line factory in electrical debugging stage, due to the transmission of ground construction is not perfect, resulting in frequent failure when debugging Siemens S120 AC drive device, such as the typical encoder speed jump, etc., main drive debug cycle is delayed, thus affecting the whole debugging period. Based on the original grounding scheme and the field grounding work actual situation analysis, respectively improved on the ground for control the main loop of the grounding line, cable, encoder cable and transmission device, eventually making debugging work smooth implementation.
