Prefabricated uninterruptible power supply system

The invention discloses a prefabricated uninterruptible power supply system. The system is characterized by comprising a prefabricated chamber and an uninterruptible power supply device located in the prefabricated chamber. A chamber body (101) of the prefabricated chamber is fixedly installed on a construction foundation (204) on site through prefabricated embedding members; the chamber body (101) is provided with standard electric joint and communication joint inside. An entire UPS system is integrated within the prefabricated chamber, and the manufacture is completed in factories before the transportation on site; the electric joint and the communication joint are standardized, and the cable jointing is completed by plugging prefabricated cables on site; in addition, the prefabricated embedding members are assembled to the site foundation previously, and the transported prefabricated chamber can be fixed to the prefabricated embedding members directly; the prefabricated chamber is provided with a cable paving, water leakage proofing, fire alarming and protecting, safety protecting, monitoring, lighting and plugging and power distribution box distributing system inside. The UPS system is integrated and standardized, the construction period is further shortened, and the projection quality is improved.
