Abstract

The invention provides a grid connection switching device for auxiliary power and belongs to the technical field of electrical equipment. The grid connection switching device for the auxiliary power comprises a shell, a liquid crystal display, an operation key, a main board, a remote signaling collection plate and a remote metering collection plate. The liquid crystal display and the operation key are installed on the surface of the shell, and connected with the main board through shell through holes. The remote signaling collection plate and the remote metering collection plate are connected with the main board. The remote metering collection plate is coupled with a power source. The grid connection switching device has the advantages of comprising a plurality of switching modes, and meeting the requirements of various power plants; the device can automatically identify the state of the auxiliary power, the optimal switching opportunity is selected, no-impact switching is achieved, and continuous uninterrupted power supply can be effectively ensured.

Description

technical field [0001] The invention relates to a grid-connected switching device for utility power, which belongs to the technical field of electric power equipment. Background technique [0002] "Plant power" refers to the power used by the power plant to provide guarantee for normal operation. When the unit is in normal operation, it uses the power supply of the generator set itself, but it has to use the online power supply for a short time or use the backup power supply in the factory when it starts, stops and accidents. Continuous and reliable power supply is the basic condition for the safe operation of various electrical equipment. Therefore, most occasions that require high reliability of power supply are equipped with two-way power supply. Successful switching between the two power sources is the key to continuous uninterrupted power supply, which is why switching power plants is used. [0003] For most domestic power plants, the high-voltage motors for plant pow...
