摘要
本刊2007年第8期发表了"大变比启动/备用变压器在大型火电厂的应用",该文着重从厂用电源引接方案可靠性和经济性的角度,论证了应用大变比启动/备用变压器的可行性和合理性。而本期发表的这篇文章,考虑到大变比启动/备用变压器的设计和制造技术还不成熟,着重从设备本身可靠性的角度,指出其应用可能给用户带来潜在的事故隐患,必须引起有关部门的重视。希望有关作者和读者踊跃来稿,对该问题提出自己的看法,问题将越辩越明,越有助于问题的解决。
The paper, ＂Application of Startup/Standby Transformer with Large Transformation Ratio in Large Thermal Power Plants＂, which was published in No. 8, 2007 issue, explained the feasibility and rationality of using startup/standby transformer with large transformation ratio from reliability and economy of auxiliary power connection schemes. However, considering the immature design and manufacturing technologies, present paper points out the potential hidden troubles of startup/standby transformer with large transformation ratio to customers. It emphasizes equipment reliability. We hope authors and readers express their opinions, which will help solving this problem.
