Abstract:

This paper presents the results of research to build models of of underground mines in Quang Ninh area with the view of safety from electrical shock. From the research results overview of the model calculated leakage in underground mines electricity network and research results about the transition to disconnect the three-phase asynchronous motor from the power supply, the authors propose a leakage current model calculation applied to the electric network voltage 1140V underground mines in Quang Ninh. A new feature of the model is telling the influence of stator voltage of large capacity engine after disconnected from the power supply to the leakage current.
