Required by the reliability and economy of the power system

the development of integrated automatic power equipment maintenance decision-making management system has become an inevitable trend.Based on the improved RCM technology

the authors developed a new maintenance decision system for switch equipments.This system is made up of basic data management

online analysis of reliability data

warning of equipment aging

optimization of maintenance schedule

and tracking of maintenance progress

thereby it can improve the maintenance decision scientifically and efficiently.An actual case demonstrates the feasibility of the proposed system in decision-making of maintenance schedule.
