Life Cycle Cost Assessment of Condition Monitoring Sensors in Smart Distribution Room

摘要

Based on the theory of life cycle analysis and the operation and maintenance statistics of Guangzhou Power Supply Bureau, the life cycle cost analysis model for intelligent power distribution room sensors is proposed and revised, and the relevant sensitivity calculation is given. The cost and cost sensitivity of each stage of the sensor are analyzed in detail, and the proportion of the life cycle costs of the six sensors is compared horizontally. The results show that the operation cost is the dominant factor in the life cycle cost of six kinds of sensors, accounting for 54.62-76.90%; high procurement costs bring about quality improvement, which can greatly reduce operating and failure costs. It provides a reference for the selection of smart power distribution room sensors from the perspective of life cycle cost.
