浅谈铁矿配电变压器低压侧主断路器的选择

Selection of Main Circuit Brea ker at Low Voltage Side of Distribution Transformer in Iron Mine

通过对日常工作中遇到的电气故障进行调查分析,探讨如何选择铁矿配电变压器低压侧的主断路器、如何进行参数整定,并以工程实例进行具体分析,以期给电气设计人员提供参考。

Through the investigation and analysis of an electrical fault encountered in the author’s daily wor k,this paper leads to the discussion on the selection of main circuit brea ker at low voltage side of iron ore distribution transformer,introduces its type selection and parameter setting,and ta kes this electrical fault as an engineering example for specific analysis,hoping to give reference to electrical designers.
