A method and device for life prediction of marine electrical equipment based on key components

Abstract

The invention relates to a life prediction method and device for marine electrical equipment based on key components. The method includes pre-entering equipment information; decomposing key components of the equipment; The life calculation model of humidity, vibration, conductivity coefficient, and working condition parameters, different types of devices correspond to different models; calculate the remaining life of the device according to the actual environmental parameters and operating conditions; divide the health of the device according to the remaining life of the device, and Formulate equipment maintenance plan and spare parts plan proposals. The present invention firstly classifies the key components of electrical equipment, predicts the life of each component, and predicts the life of the equipment, and estimates the reliability of the equipment and its component levels according to the life status, and performs the calculation according to the life status of the equipment and key components. Prioritize and develop maintenance plans and spare parts plans to increase equipment utilization and reduce inventory costs.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis and prediction of electrical equipment, in particular to a method and device for life prediction of marine electrical equipment based on key components.
