摘　　要：随着高压断路器接近设计寿命年限其触头烧蚀情况越来越严重,评估高压断路器电寿命可提高利用效率同时保证其运行可靠性。根据近些年有关开关电器电寿命相关文献,首先从触头烧蚀数学模型出发剖析了断路器电寿命终结物理过程;然后对比了目前常用的断路器电寿命评估方法优缺点,指出数据模型是驱动设备寿命准确评估的关键,并借鉴其他类型开关电器电寿命相关研究为高压断路器靠性评估开拓了思路。最后指出高压断路器电寿命预测所面临挑战以及研究方向。As high-voltage circuit breakers approach their design life and their contact ablation becomes more and more serious,evaluating the electrical life of high-voltage circuit breakers can improve the utilization efficiency and ensure their operational reliability.According to the literature related to the electrical life of switchgear in recent years,the phys-ical process of the end of electrical life of the circuit breaker is analyzed from the mathematical model of contact ablation.Then,the advantages and disadvantages of the current commonly-used assessment methods for circuit breaker electrical life are compared,and it is pointed out that the data model is the key to the accurate evaluation of the life of drive equip-ment,and the research on the electrical life of other types of switchgear electrical appliances is used to open up ideas for the reliability evaluation of high-voltage circuit breakers.Finally,the challenges and research directions of electrical life prediction of high-voltage circuit breakers are pointed out.
