摘要
介绍一种应用于煤矿井下供配电系统的低压隔爆馈电开关智能保护器,该保护器以TMS320LF2407A型DSP为控制核心,不仅具有短路、过载、漏电闭锁、漏电保护、选择性漏电保护、断相及三相不平衡保护等功能,而且具有液晶显示、故障记忆与查询、联网通讯等功能。测试结果表明,该保护器动作灵敏、工作可靠,系统的设计方案是合理可行的。
Introduces a kind of intelligent protector power supply and distribution system of coal mine, of low voltage flameproof feed switchgears used in the protector takes TMS320LF2407A-type DSP as the core control chip and the protector function is composed of short-circuit, overload, lead, lead protection, selective lead protection, phase-failure, phase imbalance and so on, more over the protector has liquid crystal display, breakdown memory and inquiries, communication function and so on. Test results show that the protector works sensitive and reliable, and the design scheme of the system is rational and feasible.
