[0002] Dedicated transformer acquisition terminals refer to user terminals that own and use dedicated transformers for power supply. Dedicated transformers are invested and built by users themselves, and their asset ownership belongs to the users. With the continuous growth of electricity demand, the balance between power supply and demand has become particularly important. Dedicated transformer acquisition terminals are usually large-power users, and their power load changes will directly affect the stability of the entire power grid. Therefore, the energy consumption information analysis system for dedicated transformer acquisition terminals is of great significance and role.

The method for analyzing energy consumption data of a dedicated transformer collection terminal according to claim 1 is characterized in that: The specific analysis methods of the power equipment operation evaluation of each designated special transformer collection terminal include: Extract the power consumption trend chart of each power equipment in the set monitoring time period from each designated special transformer collection terminal; If the power consumption trend graph of a certain power equipment at a designated special transformer collection terminal during the set monitoring period shows a fluctuating trend or a gradually decreasing trend, the operation evaluation of the power equipment at the designated special transformer collection terminal during the set monitoring period will be recorded as risky equipment operation; If the power consumption trend graph of the power equipment during the set monitoring time period of the designated special transformer collection terminal is a periodic trend, the operation evaluation of the power equipment during the set monitoring time period of the designated special transformer collection terminal is recorded as seasonal equipment operation; If the power consumption trend graph of the power equipment of the designated special transformer collection terminal during the set monitoring time period shows a gradually increasing trend, the operation evaluation of the power equipment of the designated special transformer collection terminal during the set monitoring time period is recorded as aging equipment operation; Then the operation evaluation status of each power equipment of each designated special transformer collection terminal can be obtained.

7. A method for analyzing energy consumption data of a dedicated transformer collection terminal according to claim 6, characterized in that: The specific evaluation method for the energy inefficiency reasons of each designated special transformer collection terminal is: extracting the operation evaluation status of the electric energy metering equipment and the energy efficiency evaluation status of the electric power equipment of each designated special transformer collection terminal, evaluating them according to predefined principles, and obtaining the energy inefficiency reasons of each designated special transformer collection terminal.
