Novel environmental facility uninterruptible power supply system

The utility model discloses a novel environmental facility uninterruptible power supply system, comprising a variable-frequency power source main body and a cabinet used to place the variable-frequency power source. The variable-frequency power source main body comprises a housing and a power supply circuit disposed in the housing. The system comprises a transformer and an LC low pass filter, and also comprises a variable-frequency AC uninterruptible power supply input and output breaker. The transformer and the LC low pass filter are connected in series in the power supply circuit. An end of the variable-frequency AC uninterruptible power supply input and output breaker is connected with an output end of the power supply circuit, and the other end is connected with the power supply circuit. Beneficial effects of the system are that the system effectively ensures continuity of power supply by forming inductive load by the environmental facility uninterruptible power supply system, so IT device power supply an
