Abstract

The invention relates to an emergency processing method in a communication power supply transformation process of an ultrahigh-voltage transformer substation. The method comprises the steps of replacing an original rectification module and an original power supply monitoring unit of a communication power supply with a power supply plug-in frame; detecting the output voltage of the power supply plug-in frame; and processing an alternating current power supply branch of the power supply plug-in frame and a direct current power supply branch in the communication power supply according to a presetprocessing mode under the condition of output undervoltage. The emergency processing method can be applied to a power supply plug-in frame transformation scheme. The original rectification module andthe original power supply monitoring unit on the communication power supply are dismounted, the original power supply core component is replaced by the power supply plug-in frame, original power distribution and load power supply cables are reserved, an original power supply rack is utilized to the maximum extent, and when the output voltage of the communication power supply is under-voltage, thealternating-current power supply branch of the power supply plug-in frame and the direct-current power supply branch in the communication power supply can be checked and processed according to a preset processing mode, so that the safety of communication power supply transformation is ensured.

Description

technical field [0001] The present application relates to the ultra-high voltage field, and in particular to an emergency treatment method during the transformation of a communication power supply 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 process of transforming the communication power supply of an ultra-high voltage substation (for example, 500 kV), some urgent problems often occur, and the prior art does not provide an effective solution to deal with these urgent problems. Contents of the invention [0004] In order to solv...
