which moved by the parallel connection drive of the same SCR Bridge. To the mechanical
failure of the pulley’s moving, if any one set of the two motors over the preset speed
limitation, the circuit will cut off power transported to the two motors through opening DC
pointed contactor.
指示灯和按钮安装在SCR 柜门上，指示灯亮指示皮带轮打滑调闸。按钮用于皮带轮打滑故
障复位。皮带轮打滑电路通过HEDS(霍尔传感器) 测量每台电机的电流并将这些值与SCR 桥的
电压输出相对比以探测超速情况。The indicating lights and buttons are installed on the door of
SCR cabinet, the indicating light is on and indicates slipping and off break of the pulley. The
buttons are used for the slipping failure place of pulley. The pulley slipping circuit measures the
current of each motor through HECS, and compares the value with the voltage output of SCR
bridge to detect the situation of over speed.
系统主PLC 为高速、通用组合式小型PLC。PLC 用于SCR 房与司钻台和其它钻井设备的连
接通讯。另外PLC 还完成SCR 桥逻辑指配关系。PLC 有以下特性:

7.2.5.10 绞车能耗制动装置 Arresting device of drawworks energy consumption
松开脚踏开关后，在10 到15 秒之间，能耗制动会将绞车电机的速度从全速降至预定的猫头
速度。由单向接触器将直流电机产生的电能输送到一组不锈钢网格电阻中。绞车正常工作时，能
耗制动装置不工作，任何时候绞车的实际速度高于设定速度，绞车能耗制动会自动投入工作。
