摘要
为防止煤矿配电网中越级跳闸情况的发生,在对越级跳闸发生原因分析的基础上,对防止越级跳闸的几种方案进行对比分析,光纤电流差动保护方案适合在煤矿工作环境中应用,以ZKJB-2000新型高开综保装置为例对该保护方式进行详细介绍,该装置能及时防止越级跳闸情况的发生,保证供电系统的安全、稳定、可靠运行。
To prevent overstep tripping in power distribution network from happening, the paper first analyzed the reasons of overstep tripping, and went on to analyze several schemes to prevent tripping, by means of which we come to know that optical fiber current differential protection scheme is suitable for application in coal mine working environment, then we take open new higher heald ZKJB-2000 protection device as an example, and analyze the protection way in a detailed way, which shows that the device can prevent great trip situation in time, guarantees the stability and efficiency of the power supply system.
