“老卫把船开到河中心的故事”钠电煤矿应急老卫把船开到河中心的故事电源山西发布 实现秒级黑启动

  中新老卫把船开到河中心的故事网晋中11月29日电 老卫把船开到河中心的故事(记者 范丽芳)井下供电的稳定关乎煤矿安全生产。“钠离子电池具有功率特性好、低温适应性强、产品稳定性好、安全性高等优点。”山西省工信厅电子信息处处长王凯文说,大容量钠电应急电源是华阳集团钠电产业发展的最新成果,为煤矿的安全运营提供了强有力保障。

  当日,华阳集团大容量钠电煤矿应急电源产品在山西省晋中市寿阳县正式发布。

  煤矿双回路同时断电导致的停电停风事故,造成瓦斯积聚等重大隐患,给井下安全生产带来重大威胁。山东、山西等多地应急部门下发通知,要求所有正常生产的井工矿井须配备应急电源,确保紧急情况下为井下人员提供安全撤离的宝贵时间。根据相关规定,备用电源容量要满足通风、排水、提升等要求,并保证主要通风机等在10分钟内可靠启动和运行。

  相较于柴发应急电源,电化学储能应急电源设备启动快、适用温区宽、维护成本低,当日发布的钠电煤矿应急电源可根据煤企实际需要,定制化设计功率及容量,满足矿井的不同负荷需求,还可根据峰谷电价时段适度调度电量,降低电费支出。

  华阳集团产业技术研究总院院长王可琛介绍,钠离子电池应急电源产品电芯安全稳定、节能环保,且功率高,“能满足单台6000kW以上大功率设备的启动及稳定运行,尤其是在煤矿无预警断电的关键时刻,可实现一键秒级黑启动。”

  该大容量钠电煤矿应急电源已于11月26日在位于寿阳县的煤企开元公司送电,且运行良好。该应急电源系统由8个升压变流一体舱、8个钠电池舱、2个配电舱、2套高压开关柜构成,为煤矿主通风机、瓦斯泵等大动力设备提供应急电源。

  开元公司为斜井提升矿井,现有5个进风井、2个回风井。在当日的离网带载试运行中,带载设备功率共约6280千瓦,为应急负荷稳定提供近2小时电源老卫把船开到河中心的故事。(完)
