摘要
高压SF_(6)断路器作为变电站中重要的电气设备,其可靠性对电力系统的稳定运行至关重要。然而,在长期运行中,断路器可能遭遇多种故障,影响其正常运行和性能。因此,本文旨在对高压SF_(6)断路器在变电检修中常见的故障进行分析,并探索相应的检修技术。首先,收集大量的现有文献和实际案例,对高压SF_(6)断路器在变电检修中出现的常见故障进行归纳总结。其次,分析变电站断路器的故障诊断预兆情况。再次,提出一种基于自适应变异萤火虫算法的断路器故障诊断方法。最后,通过数值实验分析,对不同故障情况下的SF_(6)断路器进行测试和分析。结果表明,通过采用本文方法,能够有效解决高压SF_(6)断路器的常见故障问题,提升设备的可靠性和稳定性。
As an important electrical device in substations,the reliability of high-voltage SF_(6) circuit breakers is crucial for the stable operation of the power system.However,during long-term operation,circuit breakers may encounter various faults that affect their normal operation and performance.Therefore,this article aims to analyze common faults of high-voltage SF_(6) circuit breakers in substation maintenance and explore corresponding maintenance techniques.First,a large amount of existing literature and practical cases were collected to summarize the common faults that occur in the maintenance of high-voltage SF_(6) circuit breakers.Secondly,the predictive symptoms of fault diagnosis for substation circuit breakers are analyzed.Then,a fault diagnosis method for circuit breakers based on an adaptive mutation firefly algorithm is proposed.Finally,through numerical experiments,the SF_(6) circuit breakers under different fault conditions are tested and analyzed.The results show that by adopting the method in this article,common faults of high-voltage SF_(6) circuit breakers can be effectively solved,improving the reliability and stability of the equipment.
