摘要
根据矢量磁位叠加原理,结合故障过程中环流对电感量的影响,提出了空心电抗器匝间短路状态下电感的计算公式。通过0.618法进行椭圆积分值的查询,该公式能够实现对不同故障位置、不同短路线匝数的干式空心电抗器电感量准确而快速的计算,这将为今后匝间故障诊断系统参数的选择提供依据。
According to the principle of vector magnetic potential superposition,as well as the influence of circu- lation on inductance in the fault process, this paper derives the inductance calculation formula in the condition of air-core reactor inter-turn short circuit. Based on the elliptic integral value query by 0. 618 method, the for- mula can achieve accurate and rapid computation of dry-type air-core reactor inductance in different fault loca- tions and with different short-circuit line turns, providing the parameter selection basis for inter-turn fault di- agnosis.
