Description

双路输入备用电源***
技术领域
本发明涉及一种双路输入备用电源***。
背景技术
电信、金融等行业所用的许多电器设备均不允许电力供应中断的情况发生，为保证电力供应顺畅，业界通常使用冗余的后备电源***为电器设备供电。常用的冗余后备电源***如图1所示，第一交流电源11及第二交流电源12分别通过第一开关电源转换电路21及第二开关电源转换电路22转换为直流电，然后通过由二极管与电容器所组成的整合电路30向电器设备供电，这样即使两路交流电源中有一路异常也可以确保正常供电。但该***需要使用两组开关电源转换电路及相应的整合电路，从而导致供电***体积庞大、成本较高。
发明内容
鉴于上述内容，有必要提供一种体积小、成本低的双路输入备用电源***。
一种双路输入备用电源***，包括一第一交流电源、一第二交流电源及一向用电设备供电的开关电源转换电路，所述双路输入备用电源***还包括一电力继电器，所述第一交流电源及第二交流电源通过所述电力继电器电连接至所述开关电源转换电路，当所述第一交流电源正常供电时，所述电力继电器选通所述第一交流电源向所述开关电源转换电路供电；所述第一交流电源失效时，所述电力继电器选通所述第二交流电源向所述开关电源转换电路供电
相较现有技术，所述双路输入备用电源***使用电力继电器在两路交流电源中切换，节省了电源转换电路及整合电路，从而减小了电源***的体积，降低了成本。
附图说明
下面结合附图及较佳实施方式对本发明作进一步详细描述：
图1是现有电源***的电路图。
图2是本发明双路输入备用电源***较佳实施方式的电路图。
具体实施方式
请参照图2，本发明双路输入备用电源***的较佳实施方式包括一第一交流电源110、一第二交流电源120、一电力继电器200及一开关电源转换电路300。所述第一交流电源110的火线L与中性线N分别连接至所述电力继电器200的第一通道210与第二通道220的常开点1NO、2NO，所述第二交流电源120的火线L与中性线N分别连接至所述电力继电器200的第一通道210与第二通道220的常闭点1NC、2NC，所述电力继电器200的控制线圈230连接至所述第一交流电源110，所述电力继电器200的输出端连接至所述开关电源转换电路300的输入端，所述开关电源转换电路300的输出端向用电设备供电。
所述电力继电器200由其控制线圈230控制，所述第一交流电源110供电正常时，亦即所述电力继电器200的控制线圈230通电时，所述电力继电器200的第一通道210与第二通道220均处在常开点，此时所述电力继电器200选通输出所述第一交流电源110；所述第一交流电源110失效时，亦即所述电力继电器200的控制线圈230断电时，所述电力继电器200的第一通道210与第二通道220均处在常闭点，此时所述电力继电器200选通输出所述第一交流电源120。本发明采用电力继电器在两路交流电源中切换，节省了供电***所需电子元件，从而减小了供电***的体积，降低了供电***的成本。
