摘要
介绍了各种液压支架电液控制系统的电源配置方式。指出在煤矿井下供电网络电压波动较大的情况下,电源负荷量过高会影响系统工作的稳定性和可靠性。提出了推溜作业单元和移架作业单元分电源组供电以及在多架推溜中进行浮动编组和差时起动的电源管理策略。
Power supply systems and configurations in electro - hydraulic control systems of powered support are presented. Test running indicates that too large charge output from power supply will be disadvantage to running stability and reliability of electro - hydraulic control system on large voltage fluctuate in mine. This paper develop method to manage power supply that the power supply of supports advancing chain conveyor can not be one of the advancing support, difference - time start and drift grouping can be programmed in the work of multi - support advancing chain conveyor.
