摘要
变电站中第二套母线保护作为保障电力系统安全稳定运行的关键防线,其可靠性是行业关注的焦点。本文围绕着某500 kV变电站里BP-2B装置频繁出现的电流互感器(TA)断线缺陷,展开了深入的剖析工作,详细阐述了该缺陷从发现到处理的整个过程,深入分析了电流互感器断线的判断方法、处理办法,以及产生这些缺陷的原因;结合实际发生过的案例,还揭示出该装置在实际运行过程中存在的潜在问题,并从技术改进、运行维护等多个角度提出了全面的应对措施和建议。本文研究成果能为保障电力系统稳定运行、提高BP-2B装置的可靠性提供有力的参考。
The second set of busbar protection in substations serves as a crucial defense line for ensuring the safe and stable operation of power systems,and its reliability is a focus of the industry.This paper conducts an in-depth analysis of the frequent TA disconnection defects of the BP-2B device in a certain 500 kV substation,elaborating on the entire process from the discovery to the handling of the defect.It also delves into the methods for identifying current transformer disconnections,the handling approaches,and the causes of these defects.By combining actual cases,it reveals potential issues in the actual operation of the device and proposes comprehensive countermeasures and suggestions from multiple perspectives such as technical improvements and operation and maintenance.This not only provides a strong reference for ensuring the stable operation of power systems but also enhances the reliability of the BP-2B device.
