Description

一种可自动切换的采集终端备用供电装置
技术领域
本发明涉及电工技术领域，尤其涉及一种可自动转换的采集终端备用供电装置。
背景技术
目前随着用电信息采集建设的愈发完善，国网公司对于用电信息采集终端的上线率、采集成功率及全量数据的指标要求也日趋严格。用电信息数据采集作为智能电网的重要组成部分，采集成功率的高低也代表着用电信息采集***的可靠性的高低及供电公司的管理水平的高低，因此供电公司也更加去关注采集成功率，并慢慢将其作为重要的考核指标。
但现如今现场的部分季节性用电客户、高压双电源切换用户或者停电故障高发区的终端经常面临用电信息采集终端停电问题，导致无法时刻监测用户用电情况，数据无法抄读，严重影响了考核指标的同时也影响到线损核算及电费核算等核心业务的开展。因此保障了这些用户的终端在线率，才能保证指标考核。
针对季节性用电客户，目前为了保证采集终端供电，采用变压器长期空载运行的方式，这样导致线损增加，且会严重影响变压器的使用寿命，反而得不偿失。同时，部分地区使用双市电电源供电的方案，此方案施工浪费时间，耗费大量人力物力，造成了极大地资源浪费。
目前常见的采集终端备用供电装置多为单纯电池储能进行供电的设备，转换效率低，供电时间较短，不存在长时间续航；防护等级普遍不高，不太适用于户外场景；且无法根据电网侧情况决定其是否进行输出，不能更加智能去解决供电问题；供电等级单一，无法适应现场多种电压等级；缺乏技术手段和工作繁重是一直摆在电力营销人员面前的工作难题。
发明内容

电压检测单元：用于监测电压大小与等级；
所述的光伏充电单元与电池单元相连；电压检测单元、电池单元与电压输出单元相连；参数通信设置单元与光伏充电单元、电池单元、电压检测单元、电压输出单元相连。
本发明装置的进一步特征在于：
进一步地，光伏充电单元将太阳能转换为电能后，进行升压转化，将电能存贮进入能量单元。
进一步地，能量单元能够接收光伏充电单元带来的能量。
进一步地，所述电压输出单元能够输出57.7V、100V、220V三种电压等级的电压。
进一步地，所述电压检测单元检测电网电压，将信号输出到电压输出单元，根据信号情况决定输出电压情况。
本发明的有益技术效果：解决了停电台区的终端与电表的供电问题，能够实现智能检测，根据电网来电情况自动切换，解决了停电提前安装，来电后拆除的问题，大大减少了现场人员的施工量；具备多种电压等级，兼容不同等级规格终端，解决了不同电压等级需要多种设备的问题，减轻了现场人员的工作量；采用独特的光伏充电机制，保证设备长时间供电运行，在长期无市电情况下对用电信息采集终端及电表供电，解决了定期更换电池的的问题，保证了上线率及全量数据采集指标；自主设计高防护机箱，解决了设备环境使用受限的问题，适用于多种应用工况；能够切换57.7V/100V/220V不同电压规格，适应现场多种电压等级，同时能够在电网侧来电后快速、智能切换至电网供电，无需人工干预，可以适用于室内室外多种应用环境。
