Description

交直流一体化后备电源系统
技术领域
本发明涉及一种电源系统,具体地讲,本发明涉及一种后备电源系统,特别是交直流一体化后备电源系统。
背景技术
当今,移动通信已得到普及,如何进一步保证通信畅通已上升为通信商最大的服务质量问题。为了做到所辖服务区域通信讯号无死角、无盲区,通信商必须在适当位置建立通信基站。对于人口密集的城市而言,因城市土地资源稀贵,政府没有足够的土地资源配置,普建规模较大的宏基站是不现实的。通信商针对宏基站建设难的问题,研制出一种通信微基站,相对于宏基站来说,通信微基站容量小、体积小,重量轻,它可依附在城市居住小区、商场或机关大楼顶层而建。此种易安置的通信微基站可作为宏基站功能的补充,最大好处是便于做到有针地性地布点安置,这样才能实现最大可能消除通信盲区。现实中,不管是宏基站还是通信微基站都存在全天候24小时不间断供电问题,只有持续供电才能确保通信畅通。因宏基站容量大、配置全、占地大,它内部有足够空间安置外形尺寸稍大的不间断电源。通信微基站因安置位置分散,被停电的概率相对较多,再加上通信微基站体积较小,安置位置特殊,故不适合配置现有技术的不间断电源,由于市场上缺少体积小,而且能瞬时转换供电的不间断电源供应,现有技术仅解决通信微基站合理布局问题,而没有有效解决断电后不能正常工作的问题。
发明内容
本发明主要针对现有技术体积大、转换供电及时性差的问题,提出一种适合通信微基站应用的交直流一体化后备电源系统,该系统集成的产品体积小、重量轻、价格低廉、环境适应能力强、使用和维护都很方便,最重要的是能够做到瞬时转换供电。
本发明通过下述技术方案实现技术目标。
交直流一体化后备电源系统,它包括配电单元、UPS模块和电池组B。所述配电单元由防雷器—F1、温控器WK、风机FN、加热器JR、交流输入空气开关接口—S1、交流输出空气开关接口—S2、—S3、—S4和—S5,还有直流输入空气开关接口—S6、直流输出空气开关接口—S7和—S8共同组成。其改进之处在于:所述UPS模块设有交流输入接口、交流输出接口,直流输入接口和直流输出接口,UPS模块中的交流输入接口与配电单元中的交流输入空气开关接口—S1对接,该空气开关的另一端与防雷器—F1并联后共同接入市电。配电单元中用于连接直流负载的直流输出空气开关—S7和—S8并联后与UPS模块的直流输出接口对接,构成直流负载可控电路。所述电池组B采用串联连接,电池组B的正极和负极分别与UPS模块直流输入接口的正极和负极配对对接,在负极电路中串联直流输入空气开关接口—S6。所述交流输出空气开关接口—S2、—S3、—S4和—S5并联后与UPS模块的交流输出接口对接,其中的交流输出空气开关—S2和—S3分别连接交流负载,构成对交流负载的可控电路。交流输出空气开关—S4连接加热器JR,交流输出空气开关—S5的线路中串联温控器WK后并联风机FN,由此构成后备电源系统内置温度调控电路。
作为进一步改进方案,所述电池组B由4只12V铅酸蓄电池串连而成。
作为进一步改进方案,所述加热器为板式电加热器。
本发明与现有技术相比,具有以下积极效果:
1、后备电源系统采用交直流一体化设计,技术合理,采用智能化控制,能够做到瞬时调控供电状态;
2、后备电源系统采用交直流一体化设计,可满足不同负载的供电需求;
3、制成的产品体积小、重量轻、特别适合通信微基站配套。
附图说明
图1是本发明原理图。
具体实施方式
下面根据附图并结合实施例,对本发明作进一步说明。
图1所示的交直流一体化后备电源,它包括配电单元、UPS模块和电池组B。所述配电单元是本发明用于控制外连接的电路,它由防雷器—F1、温控器WK、风机FN、加热器JR、交流输入空气开口接口—S1,交流输出空气开关接口—S2、—S3、—S4和—S5,还有直流输入空气开关接口—S6、直流输出空气开关接口—S7和—S8共同组成。本发明所述UPS模块共设四道接口,分别为交流输入接口、交流输出接口,直流输入接口和直流输出接口,其中的交流输入接口直接与配电单元中的交流输入空气开关接口—S1对接,该空气开关的另一端与防雷器—F1并联后共同接入市电。配电单元中用于连接直流负载的直流输出空气开关—S7和—S8并联后与UPS模块的直流输出接口对接,此对接构成直流负载可控电路。所述电池组B是后备电源的主体构件,本实施例电池组B由4只12V铅酸蓄电池串连而成。电池组B正极和负极分别与UPS模块直流输入接口的正极和负极配对对接,在负极电路中串联直流输入空气开关接口—S6。所述交流输出空气开关—S2、—S3、—S4和—S5用于外连接,四只交流输出空气开关并联后与UPS模块的交流输出接口对接,本实施例中的交流输出空气开关—S2和—S3分别连接交流负载,直接构成对交流负载的可控电路。因本发明制成的产品应用于通信微基站,露天安置所处环境相对恶劣,故将产品安置在防雨水的机柜内,产品安置在机柜内必然存在柜内温度调节问题,本实施例利用交流输出空气开关—S4连接一种板式电加热器JR,并且在交流输出空气开关—S5的线路中串联温控器WK,然后再并联两台风机FN,由此构成后备电源系统内置温度调控电路。
正常情况下,由配电单元引入市电为电池组B、UPS模块、风机FN、加热器JR及各负载单元供电,一旦所在位置市电突发异常或停电,本发明产品则瞬时自动转换成由电池组B对UPS模块、风机FN、加热器JR及各负载单元供电,确保负载单元正常工作。另外,当本发明产品所处环境温度高于温控器WK设定温度,风机启动实施机柜内降温,待柜内温度降至常温时,在温控器WK作用下风机FN停止工作。若本发明产品所处环境温度低于温控器WK设定温度时,板式电加热器JR得电而加热,使得机柜内增温,经过上述调控使本发明产品在安装位置上始终处在一个合适的温度环境下工作,确保后备电源系统稳定运行。
