Abstract

One or more embodiments of the invention provide a method and device for intelligently monitoring the operation state of a distribution transformer. The method comprises the steps of: transmitting original operation data to an edge IOT proxy device for edge calculation, and obtaining the operation information of the distribution transformer; performing logic judgment processing on the obtained operation information and preset operation standards, sending out a corresponding operation report; and finally sending the operation report to an Internet of Things management platform, a marketing mainstation and a power distribution main station. Therefore, the task load of the Internet of Things management platform, the marketing main station and the power distribution main station is reduced, the power data processing efficiency is improved, the operation state of the distribution transformer is intelligently monitored, the faulted distribution transformer can be checked and overhauled in time, and the operation reliability of the distribution transformer is greatly improved.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of transformer operation monitoring, and in particular to a method and device for intelligent monitoring of distribution transformer operation status. Background technique [0002] The distribution transformer is an important equipment in the distribution network. It is at the end of the distribution network. As the final link to supply power to users, it plays an important role in the reliability requirements of the entire power supply network. It is important to determine whether the operating status of the distribution transformer is normal. Improving the reliability of power supply plays a decisive role. [0003] In the existing technology, the collected distribution transformer operation data is usually uploaded to the main distribution station for calculation and analysis, and then the abnormal results are obtained, and then corresponding measures are taken to repair the ...
