摘要
通过工程实例计算及分析,阐述了自并励静止励磁系统中励磁变压器相电流速断保护的重要性,并从保护的可靠性、快速性、选择性和灵敏性几个方面分析了励磁变相电流速断保护几种整定计算方案的优劣,为工程应用中励磁变压器相电流速断保护的整定计算提供了参考。
This paper calculates the result by the project example, expounds the importance of instantaneously over-current protection on the bus fed static excitation system, and analyzes the excellence and defect of several project of phase current instantaneous trip protection on exciting transformer by reliability, quick-action, selectivity and sensitivily of the protection. It may offer the reference for the setting calculation of phase current instantaneous trip protection on exciting transformer.
