摘要
介绍了一种煤矿井下连续采煤机变频调速装置的软硬件设计方案。首先根据连续采煤机对变频器的要求选用了矢量变频器,然后重点探讨了变频调速装置的主回路、控制回路、漏电保护电路、散热模块及软件部分的设计。该装置实现了对连续采煤机的行走控制。现场应用表明,该变频调速装置不仅实用可靠,而且检修、维修方便。
Design schemes of hardware and software of a frequency-conversion speed-regulation device of continuous shearer were introduced.Firstly the vector frequency converter was selected according to requirements of continuous shearer on frequency converter,then designs of main circuit,control circuit,leakage protection circuit,radiate module and software of the device were discussed in details.The device realizes motion control of continuous shearer.The field application indicated that the device is practical and reliable and has easy maintenance.
