Abstract

The invention discloses a transformer loop closing control circuit, and a transformer loop closing control method and apparatus. The transformer loop closing control method includes the steps: determining whether or not to close an electronic switch, wherein the electronic switch is connected with a transformer loop closing control circuit and is used for disconnecting the transformer loop closing control circuit during the disconnection process and conducting the transformer loop closing control circuit during the closing process, and the transformer loop closing control circuit is used for executing loop closing on a first channel power supply inlet wire and a second channel power supply inlet wire during the conduction process; and controlling closing of the electronic switch to conduct the transformer loop closing control circuit if the electronic switch is closed according to the determination result. By means of the transformer loop closing control circuit, and the transformer loop closing control method and apparatus, the problem that in the related art, the loop closing current which is generated at the loop closing moment of a transformer is solved.

Description

technical field [0001] The invention relates to the field of circuits, in particular to a transformer loop closing control circuit, a transformer loop closing control method and a device. Background technique [0002] The transformer usually uses two power supply lines for power supply, and each power supply line has a corresponding power load to prevent failure of one of the power supply lines and provide guarantee for the normal power supply of the distribution network. Under normal circumstances, the two power supply lines are operated separately, and the separate operation of transformers has the characteristics of improving the power supply reliability and flexibility of the power supply system, reducing losses, and expanding the capacity of the power supply system. However, in special cases, the two power supply lines It needs to communicate with each other, and the transformer needs to perform the operation of live-to-parallel operation for the transformers operating ...
