The invention provides a power supply device and method and equipment thereof, and relates to the technical field of electric power. The power supply device comprises a power supply interlocking power supply module, a power supply switching module and a battery module. The power supply interlocking power supply module is connected with the at least two power supplies and used for outputting electric energy of one of the at least two power supplies when the at least two power supplies do not fail at the same time. The power supply switching module is respectively connected with the power supply interlocking power supply module, the battery module and the load and is used for supplying power to the load by using the electric energy output by the power supply interlocking power supply module under the condition that the power supply interlocking power supply module outputs the electric energy, and controlling the battery module to supply power to the load under the condition that the power supply interlocking power supply module does not output the electric energy. According to the power supply device and method and the equipment thereof, self-switching of electric energy provided for the load can be achieved, multi-level electrical protection can be provided, and safe and reliable operation of the equipment can be guaranteed.
Description
technical field [0001] The present disclosure relates to the field of electric power technology, in particular to a power supply device, method and equipment thereof. Background technique [0002] Power supply devices are provided in various devices. For example, the group control cabinet is an important equipment of the cold source system, which is widely used in shopping malls, subways and other important occasions. At present, the power distribution of the group control cabinet usually adopts a single-circuit power supply device. When the upper-level power supply equipment fails or has electromagnetic interference, a trip and power failure will occur. The above situations will cause the teamwork control cabinet to lose power temporarily, and the stability of the equipment operation is poor. Contents of the invention [0003] In view of this, a technical problem to be solved in the present disclosure is to provide a power supply device, method and equipment thereof, wh...
