间歇性电流电力电缆研究

Research on Discontinues Current Power Cable

针对在热核聚变时电力电缆间歇性大交流电,导致电缆温度升高进而破坏电缆绝缘的情况,提出建立基于电缆暂态热路模型,以迭代优化算法来推导电缆导体温度变化规律,对该电缆的结构进行优化设计。通过实验验证了该算法能对间歇性交变电流下电缆导体温度变化正确描述,为热核聚变电缆的研制提供了依据。

Intermittent large alternating current in the thermonuclear fusion time passes through the power cable,causing the cable temperature to rise and damaging the cable insulation.To solve the problem,a transient thermal path model is proposed to study the change of cable temperature by using iterative optimization algorithm,and the structure of the cable is optimized.The correctness of the cable temperature intermittent high pulse current is verified through tests,which provides a basis for the development of thermonuclear fusion cable.
