煤矿井下供电系统短路保护方法浅析

Brief Analysis of Short Circuit Protection Method of Underground Power Supply System in Coal Mine

下文立足于煤矿井下生产实际特征以及供电系统短路问题,首先阐述了煤矿井下供电系统短路保护技术要求,然后根据时下国内外的供电系统短路保护技术,提出了Ether CAT分站技术,总结出煤矿井下供电系统短路保护不仅仅要注重基础措施的落实,还要注重高新技术方法的应用。

The following is based on the actual characteristics of underground coal mine production and the short circuit problem of power supply system,firstly,the technical requirements for short circuit protection of underground power supply system in coal mines are described.Secondly,according to the current short circuit protection technology of power supply system at home and abroad,the ether cat substation technology is proposed,it is concluded that the short-circuit protection of underground power supply system in coal mine should not only pay attention to the implementation of basic measures,but also pay attention to the application of high-tech methods.
