摘　　要：传统矿井电网单相漏电的各序网络模型只能描述单相漏电的稳态特征,为此采用瞬时对称分量法建立了矿井电网单相漏电瞬时序网络模型,该模型可用于分析单相漏电的暂态和稳态特征,并利用该模型给出了单相漏电的瞬时零序电压和瞬时零序电流的数学表达式,可为单相漏电保护研究提供参考。Traditional sequence network models of mine distribution network can but describe steady state characteristic of single-phase leakage of this network, for this reason by use of instantaneous symmetrical component an instantaneous sequence network model of single-phase leakage in mine distribution network is built. The proposed model can be used to analyze transient and steady state characteristics of single-phase leakage, and based on this model the mathematical expressions of instantaneous zero sequence voltage and zero sequence current under single-phase leakage, which is available in the research on single-phase leakage protection, are deduced.
