变压器电流与容量的估算

Estimation on Transformer Current and Capacity

介绍了用经验系数来估算变压器额定容量和电流的口诀。分析了电力变压器电流和负荷功率、单相变压器容量、行灯变压器一次侧电流估算公式的推导过程。指出了将实践经验与理论知识有机结合,有利于普及变压器电流与容量的速算法在变压器安装、运行和维护中的应用。

Introduction was made to using pithy formula experience coefficient to estimat transformer rated capacity and current. Analysis was made to power transformer current and load power, single phase transformer capacity, deriving process of transformer pri- mary side current estimation formula. It is pointed out that to take practical experience and theoretical knowledge to be unify organically will be popularize the application of transformer current and capacity rapid estimation in transformer installation, movement and maintenance.
