摘要
分析了井下高压电网系统,提出了基于多机通讯的防越级跳闸设计方案。设计了以LPC2131为主控单元的微机高压保护装置,介绍了装置的硬件构成。经现场试运行,性能良好。
The plan of multi-processor commutation to avoid override trip is put forward based on the analysis of underground high-voltage distribution network. The micro-computer high-voltage protection device as LPC2131to main control unit is design, the hardware elements of device is introduced. After trial operation in the field, the performance is good.
