发展设备诊断技术,进行状态检修,改变以往的定期检修,避免“过剩维修”或“维修不足”是大力发展计算机应用的一个新兴而重要领域。水电厂在实现全厂计算机监控和全厂自动化后,迫在眉睫地提出对水轮发电机组运行状态诊断技术的需要,其中,机组振动摆度量的在线监测尤为重要。 The development of equipment diagnostic techniques, the state maintenance, change the regular maintenance, to avoid “overprovision ” or “inadequate maintenance ” is to develop a new and important area of ​​computer applications. After realizing the computer monitoring and factory automation of the whole plant, the hydropower plant is eager to put forward the need of diagnosing the operating status of hydro-generator sets. Among them, the on-line monitoring of the unit vibration swing amount is very important.
