| 摘要:纸机电气传动系统的交流变频调速利用PROFIBUS现场总线协议通讯格式来实现变频器通讯及控制，笔者在总结维修实践的基础上，对该电气传动系统在运行中因纸机外部工艺参数变化而致使纸机车速不稳定及某分部随机跳停和变频器硬件缺损等故障检修进行剖析。 |
| Abstract:Nowadays paper machine drive systems of DC main shaft and SCR DC drive control unit have been gradually replaced by AC variable frequency and speed drive. From the small range variable speed drive to high precision, fast response, wide range variable speed drive, from the single drive to multiple segments coordination, PROFIBUS fieldbus protocol format is used to achieve communication and control of frequency converter, which is with high efficient drive and good control characteristics, and is widely used in papermaking industry. Based on maintenance practice, the author analyzed the reasons of speed instability, rundownly stop of some part and defects of inverter hardware. |
