Communication power supply transformation method of ultrahigh-voltage transformer substation

Abstract

The invention relates to a communication power supply transformation method of an ultrahigh-voltage transformer substation. The method comprises the steps of connecting a temporary power supply into acommunication power supply in parallel; adjusting the temporary power supply, and supplying power to communication equipment through the temporary power supply; removing the communication power supply from a power supply rack; and mounting a pre-prepared power supply plug-in frame on the power supply rack, connecting the input end of the power supply plug-in frame with alternating current, and connecting the output end of the power supply plug-in frame with the communication equipment. According to the invention, uninterruptible power transformation of an old power supply is realized, in theprocess of dismounting a rectification module and a 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; original power distribution and load power supply cables are reserved, rearrangement of the cables is reduced, normalwork of a load is guaranteed, transformation risks are reduced to the maximum extent, the 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, in particular to a method for transforming a communication power source 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] Ultra-high voltage substation (for example, 500 kV) communication power transformation is difficult, the cycle is long, and the risk of business cutover is high. Since the ultra-high-voltage substation infrastructure was put into operation, it is difficult to renovate the communication power supply without power failure, and the comm...

AI Technical Summary

Problems solved by technology

Since the ultra-high voltage substation infrastructure was put into operation, it is difficult to transform the communication power supply without power outage, and the communication power supply generally runs for a long time. Most of the stations have been out of service, facing difficulties such as the suspension of communication power supply and the lack of spare parts, and some communication power supplies do not have the conditions for transformation.
