技术领域
本发明属于火力发电厂、变电站、生产车间以及民用商用供电场所内低压回路供电系统,具体涉及一种成套低压储能供电装置。
背景技术
在火力发电厂、变电站、生产车间以及民用商用供电系统中,常配备交流低压供电设备,从发电机出口处或电网处引接电源并电压转换,为低压照明、通讯、电动执行机构等小负荷设备供电。配置事故柴油发电机、UPS(交流不停电装置)等应急供电设备,在突发断电情况时给必要负荷设备供电。
但实际应用中,应急供电设备仍存在很多不足,如设备成本过高,柴油发电机启动时间过长,交流不停电装置运行维护复杂等。
发明内容
本发明的目的是解决目前低压应急供电设备成本过高,柴油发电机启动时间过长,交流不停电装置运行维护复杂的技术问题。
为实现以上发明目的,本发明提供一种成套低压储能供电装置,包括低压开关柜、主工作电源和应急备用电源;
所述主工作电源为从外部接入所述低压开关柜的交流市电,低压开关柜内通有长母线,所述主工作电源连接至所述长母线;所述长母线处引出多路为各用电设备供电的分支线;
所述应急备用电源为蓄电池,所述蓄电池安装在所述低压开关柜内,所述蓄电池输出的直流电经逆变器、输出变压器、静态开关、输出开关和第一保护开关转变成低压交流电后连接至所述长母线;
正常情况时,所述主工作电源为用电设备供电;待有突发应急情况时,切除所述主工作电源,自动投入所述蓄电池,继续为用电设备提供低压交流电源。
进一步地,所述主工作电源经第二保护开关后,一路连接至所述长母线,另一路连接在所述静态开关和输出开关之间,以便在正常情况下通过所述主工作电源为所述蓄电池充电储能。
进一步地,所述蓄电池与所述逆变器之间连接有电池组维护开关。
进一步地,所述低压开关柜的柜体由碳钢成型,其前、后分别安装有手动检修门,内部安装有照明灯具和控温装置。
进一步地,所述长母线和/或各所述分支线上安装有电流表和/或电压表,用于监测电源运行状态。
进一步地,所述蓄电池连接有蓄电池检测仪,当所述蓄电池异常时发出报警信号,便于巡检人员监察。
与现有技术相比,本发明的有益效果是:
本发明运行简单方便,与UPS装置、柴油发电机相比造价明显降低,占地面积明显减少,并且能快速投入备用电源,提高安全稳定等级,且便于组装运输。
附图说明
图1是本发明一个实施例的原理图。
具体实施方式
下面结合附图和具体实施例对本发明作优选说明。
如图1所示,本发明的成套低压储能供电装置,包括低压开关柜、主工作电源和应急备用电源;
主工作电源为从外部接入低压开关柜的交流市电,低压开关柜内通有长母线,主工作电源连接至长母线;长母线处引出多路为各用电设备供电的分支线,如图所示的U1……U15等,用于连接各种实际用电设备;
应急备用电源为蓄电池,蓄电池安装在低压开关柜内,蓄电池输出的直流电经逆变器、输出变压器、静态开关、输出开关和第一保护开关转变成低压交流电后连接至长母线;
正常情况时,主工作电源为用电设备供电;待有突发应急情况时,切除主工作电源,自动投入蓄电池,继续为用电设备提供低压交流电源。
优选地,主工作电源经第二保护开关后,一路连接至长母线,另一路连接在静态开关和输出开关之间,以便在正常情况下通过主工作电源为蓄电池充电储能。
优选地,蓄电池与逆变器之间连接有电池组维护开关。
优选地,低压开关柜的柜体由碳钢成型,其前、后分别安装有手动检修门,内部安装有照明灯具和控温装置。
优选地,长母线和/或各分支线上安装有电流表和/或电压表,用于监测电源运行状态。
优选地,蓄电池连接有蓄电池检测仪,当蓄电池异常时发出报警信号,便于巡检人员监察。
本发明工作时,在外部交流市电正常的情况下,始终由交流220V或380 V主工作电源为各用电设备供电,且同时为蓄电池充电。主工作电源通过保护开关直接与母线连接,给母线供电。当市电出现故障时,通过带有电压信号检测功能的电源自动切换装置,将母线自动切换到由蓄电池供电。当市电恢复正常时,经巡检人员安全确认后,再次人工切换到主工作电源供电。
以上述依据本发明的理想实施例为启示,通过上述的说明内容,相关工作人员完全可以在不偏离本项发明技术思想的范围内,进行多样的变更以及修改。本项发明的技术性范围并不局限于说明书上的内容,必须要根据权利要求范围来确定其技术性范围。
