Abstract

The invention relates to a power supply debugging method for communication power supply transformation of an ultrahigh-voltage transformer substation. The method comprises the steps of: connecting a temporary power supply to a communication power supply in parallel; powering up the temporary power supply, and supplying power to a power supply load of the communication power supply through the temporary power supply under the condition that the temporary power supply is verified to be available; and disconnecting the circuit connection of the communication power supply, and replacing the rectification module and the power supply monitoring unit of the communication power supply with the power supply plug-in frame. Uninterruptible power transformation of an old power supply is realized, in the process of dismounting the rectification module and the power supply monitoring unit on the communication power supply, the temporary power supply supplies power to the power supply load, and the power supply plug-in frame is used for replacing an original power supply core component; and original power distribution and load power supply cables are reserved, rearrangement of the cables is reduced, normal work of a load is guaranteed, transformation risks are reduced to the maximum extent, an original power source rack is utilized to the maximum extent, and the problem that the field space is not enough is solved.

Description

technical field [0001] The present application relates to the field of ultra-high voltage, and in particular to a power debugging method for the reconstruction of communication power of an ultra-high voltage substation. Background technique [0002] The communication power supply is the main power supply equipment of the substation, and the safety and stability of the equipment operation is directly related to the operation safety of the substation. The operating efficiency of the over-service communication power supply is much lower than that of the normal power supply, so it is necessary to update and replace the over-service communication power supply. [0003] In the transformation process of the ultra-high voltage substation (for example, 500 kV) communication power supply, the debugging of the power supply affects the safety of the communication power supply transformation, and affects whether the communication power supply can be successfully transformed. Based on th...
