Estimate on Safe Current Carring Capacity of Oil Impregnated Paper Insulated Cable

介绍了用经验公式估算油浸绝缘电缆允许持续载流量的口诀。分析了油浸纸绝缘电缆允许持续载流量估算口诀的来源和物理意义。指出了将实践经验与理论知识有机结合有利于普及油浸纸绝缘电缆允许持续载流量速算法在电力线路安装、运行和维护中的应用。

This thesis gives a detailed introduction of a pithy formula, which applied to estimate safe eurrent earring capacity of oil impregnated paper insulated cable with the help of experience coefficient. 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 promote the popularity of the application of safe current earring capacity of oil impregnated paper insulated cable in installation, circulation and maintenance .
