Vertical Elastic Deformation Monitoring of the Load Carrying Truss of Daxia Power Plant's Set No.1

该文叙述了新型水电机组承重机架垂直弹性变形量测试仪的研制和在大峡水电站 1号机承重机架监测中的应用。其不仅可以进行机组承重机架静态弹性变形的测试 ,也可以进行动态监测。其测试过程和方法对机组的稳定性监测和机组的验收具有实用性。图 5表 1参

The paper describes the development of an instrument for measuring the vertical elastic deformation of load carrying trusses of modern hydraulic turbine sets, as well as application of Daxia Hydraulic Power Plant's set No.1 for monitoring purposes. Not only can the elastic deformation of the load carrying truss be measured in the static state, but also in the dynamic state. The measuring process and its method is of practical use for monitoring the operational steadiness of sets as well as for their acceptance procedures. Figs 5, table 1 and refs 3
