摘要
针对传统的输变电设备定期检修存在的问题,提出以状态检修策略取代定期检修。比较了基于全寿命周期管理、基于可靠性和基于状态评价及风险评估的3种状态检修技术,认为基于状态评价及风险评估的状态检修技术优点较为突出。设备状态评价包括状态量的选取、设备状态的评价、设备状态等级的确定等方面,设备风险评估以风险值为指标,包括资产的量化、资产损失程度的确定等内容。
To solve the problems in conventional regular maintenance of transmission and transformation equipment,the strategy of condition-based maintenance（CBM） is proposed in stead.Three CBM techniques based respectively on lifecycle management,reliability,state evaluation and risk assessment are compared.It is held that the last technique is obviously advantageous.The state evaluation of equipment covers the selection of state quantities,the evaluation of equipment state,and the determination of equipment state class,etc.The risk assessment of equipment uses risk values as indices,including the quantization of assets and the determination of assets loss rate.
