浅谈连续采煤机机载变频器的抗干扰措施

The Anti-interference Measures for the Transducer Equipped on the Continuous Miner

在连续采煤机的变频调速系统中,变频器会产生和受到各种电磁干扰。指出了变频调速系统中主要的干扰源及干扰的途径,分析干扰信号的传播方式,提出了抗干扰的实际解决方法,探讨了在连续采煤机变频器应用系统设计和安装中抑制干扰的具体措施。

In the variable frequency speed control system of continuous miner,the transducer will generate and be influenced by various electromagnetic interferenceelectromagnetic interferenceelectromagnetic interferences.This paper points out the main interference sources and interference paths in the variable frequency speed control system,analyzes the modes of transmission of interference signal,puts forward some actual anti--interference measures,and probes into some concrete measures for restraining the interference in the design and installation of transducer application system on continuous miner.
