Abstract

The performance of DC circuit breakers is critical to the safety and stability of power systems. At the same time, contact degradation during repeated breaking operations significantly affects their reliability and service life. This paper proposes a remaining useful life (RUL) prediction method for circuit breakers based on comprehensive condition assessment to address the progressive deterioration of contact performance with increasing breaking cycles. A finite element simulation model of the contact system is developed to analyze the arcing erosion characteristics under various breaking conditions. Experimental measurements of the contact surface morphology after breaking operations are conducted to validate the accuracy and reliability of the simulation model. Based on this, a mapping relationship between contact performance degradation and the operational state of the circuit breaker is established by incorporating arc energy. This framework enables predictive analysis of the circuit breaker's remaining useful life, providing a robust reliability assessment and lifecycle management approach.
