摘　　要：针对现有的电位器拉线式水轮机导叶接力器位移变送装置中存在的接触不良、易磨损、输出信号不可靠的问题进行了分析。针对这些问题,运用电容式传感器原理,设计了一种新型水轮机导叶接力器电容式位移变送装置,该装置可以避免老式位移变送装置所存在的问题,能长期稳定可靠地实现线性测量水轮机导叶接力器的位移量。The author analyzes contact and easy wearing and reliability of export signal existing in potentiometer terminal model hydraulic turbine leaf of transmit water current servomotor displacement transmission equipment. A hydraulic turbine leaf of transmit water current relay machine displacement transmission device is designed based on the principles of caoacitance sensor. The device can avoid the problem of old displacement transmission, and long time and reliably measure displacement volume of hydraulic turbine leaf of transmit water current relay machine.
