摘要
通过分析变压器热稳定要求,总结了变压器后备保护定值整定应考虑的相关问题,并对变压器设计、运行及其保护配置与整定提出了建议.实践证明,采取的对策直接、有效地解决了矛盾,使变压器更加安全稳定地运行.
The thermal stability is in contradiction with the setting value for the back-up protection of the transformer because of the cascaded fitting required limitation of setting. Through analyzing the transformer thermal stability, this paper summarizes some correlative problems of setting values that should consider for transformer back-up protection, and it offers some suggestions about design, service, protective installation and setting method of the transformer. Practice has been proved that the adopted solution directly and usefully solves the contradiction, and making the transformer more securely and stably service.
