矿用变压器保护系统的改造与应用

Reconstruction Design of Mine Transformer Protection System

针对矿用变压器保护系统已无法满足当前工作面供电量增加和供电种类复杂的现状,以官地矿主变压器保护装置为研究对象,在分析其所存在问题的基础上提出采用微机保护系统实现对其传统继电保护装置的改造,并着重完成微机保护系统的硬件和软件设计,最后通过实践应用验证微机保护系统的有效性。

In view of the fact that the mine transformer protection system can no longer meet the current situation of increasing power supply and complex power supply types,the main transformer protection device of Guandi mine is taken as the research object.Based on the analysis of its existing problems,this paper puts forward a microcomputer protection system to transform its traditional relay protection device,and focuses on the hardware and software design of microcomputer protection system.Finally,the effectiveness of microcomputer protection system is verified by practical application.
