Abstract

The invention relates to the technical field of power supply, and in particular relates to a circuit for seamlessly switching between a diesel generator set and a city power supply. The circuit includes a city power supply end, and the generator set which includes at least one generator. A controller is arranged in each generator. The input end of the controller is connected with the city power supply end. The output end of the controller is connected with the control end of the generator. The circuit further includes a static selector switch. The first input end of the static selector switchis connected between the city power supply end and at least one load. The second input end of the static selector switch is connected between the output end of the generator and at least one load. Thecircuit has the advantages that the static selector switch is used between the generator set and the city power supply end, so that the generator set and the city power supply end are spare to each other; because the two power supplies are synchronized, switching is completed within a specified time difference without affecting normal supply of power; seamless switching is completed; and power quality is ensured.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a circuit for seamless switching between a diesel generator set and commercial power. Background technique [0002] In major events, conferences or exhibitions, in order to ensure the safety and reliability of power supply, diesel generator sets are used as a supplement to the mains terminal. Generally, the capacity of the generator set is designed to carry the full load. When in use, the generator set and the mains power supply are used as two power sources, each with half the load, and supply power at the same time; there is a switch between the two power sources of the generator set and the mains power supply, which are mutual backup; when one power supply fails, by switching the corresponding switch, The other power supply takes full load. [0003] However, in actual use, due to the long switching time of the mechanical dual power switch, it will cause a short-term pow...
