IMPROVING THE RELIABILITY OF HIGH-VOLTAGE CIRCUIT BREAKERS THROUGH INTELLIGENT CONDITION MONITORING

Main Article Content
Abstract
The article presents a methodology for assessing the remaining useful life of high-voltage circuit breakers and controlling the quality of wear restoration, based on a comprehensive analysis of operational data regarding the consumption of the switching resource during short-circuit current interruptions and the wear dynamics of breaker components resulting from mechanical, electrical, and thermal influences. An intelligent approach to processing diagnostic results is proposed, which includes the current assessment of the circuit breaker's technical condition, determining the schedules and scope of subsequent monitoring, tracking the wear dynamics of breaker components over time, and forming an information and methodological base to support operational personnel. It is shown that the transition from scheduled preventive maintenance to condition-based maintenance improves the efficiency of planning the schedules and scopes of restoration work while reducing the risk of making erroneous operational decisions. Special attention is paid to the automated quality control of completed repairs.
