摘要
针对目前煤矿井下6 kV电网防爆开关存在载流能力小、保护简单、故障率高等问题,文章提出了一种基于多CPU控制的高压防爆开关综合保护系统的设计方案,分析了矿井6 kV高压电网故障保护的工作原理,详细介绍了系统软硬件设计。基于多CPU控制的高压防爆开关综合保护系统采用单片机MSP430F149和DSP TMS320VC5402作为主控制器,可对各种电网信号进行综合分析,实现对高压电网的全面监测功能。实验结果表明,该系统工作稳定、动作可靠、显示准确。
Aiming at the problems of little ability of current carrying, simple protection, high fault rate of flameproof switch for underground 6 kV power grid, the paper proposed a design scheme of integrated protection system of high-voltage flameproof switch based on multi-CPU control, analyzed working principle of fault protection of 6 kV high-voltage power grid of coal mine underground, and introduced design of hardware and software of the system in details. The integrated protection system of high-voltage flameproof switch based on multi-CPU control used single-chip microcomputer MSP430F149 and DSP TMS320VC5402 as main controllers, and the main controllers synthetically analyzed all kinds of signals of power grid in order to realize function of general monitoring for high-voltage power grid. The experiment result showed that the system is stable in running, reliable in action and accurate in display.
