    • Longwall face equipment for use in extraction in underground mining, comprising electrohydraulically operated support units each having a support controller 6, with at least one power unit being provided that supplies at least two support controllers 6 of differing support units with power, and with a bi-directional coupler being connected between the power unit and the at least two support controllers 6 and providing galvanic isolation between the power unit and the support controllers 6 and/or groups I, II of support controllers 6. The couplers permit communication between the two support controllers 6 and/or groups I, II of support controllers. In order to simplify the arrangement of the face, the coupler 12 is integrated into the power unit 11 or is flanged directly onto the housing of the power unit.
    • 用于在地下采矿中提取的长壁面设备,包括每个具有支撑控制器6的电液操作的支撑单元,其中提供至少一个动力单元,其提供具有动力的不同支撑单元的至少两个支撑控制器6, 连接在电力单元和至少两个支撑控制器6之间并且在电源单元和支撑控制器6和/或支撑控制器6的组I,II之间提供电隔离。耦合器允许两个支撑件 控制器6和/或支撑控制器的I,II组。 为了简化面的布置,耦合器12集成到动力单元11中,或直接凸缘到动力单元的壳体上。
