摘　　要：介绍了用经验公式估算起重机的用电容量、起重机供配电系统的计算负荷、尖峰电流的口诀。分析了估算口诀、估算公式的来源和物理意义。指出了从电气理论和现场条件约束的角度对口诀加以归纳和总结、将实践经验与理论知识有机结合,能方便、准确地在工业现场对起重机的供配电系统进行设计、安装、运行和维护。A detailed introduction of a pithy formula, which applied to estimate the electrical parameter of power supply system used for crane, such as calculated load, peak current, with the help of experience coefficient were introduced. It also analyses the origin of the pithy formula and experience coefficient, and presents the physical prospect accordingly. Moreover, it sums the pithy formula up by putting the electric theory into practical operation ,which would useful in design,installation, circulation and maintenance of power supply system used for crane rapidly and accurately.
