How to sort out the relationship between transformers and energy meters

Abstract

The invention relates to a method for sorting power transmission and distribution lines, in particular to a method for sorting the relationships among transformers and electric energy meters. Each transformer (each busbar) is powered off for a short time (generally ten seconds), the time interval of powering off between every two transformers is more than ten minutes, and then powering down records of the intelligent electric energy meters are copied and read through a hand-held meter reading machine. The administrative relationship between each transformer and each electric energy meter can be distinguished according to powering off time of each electric energy meter and corresponding powering off time of each transformer. According to the method, powering off time is very short and electricity utilization of users is basically not affected. Moreover, the method is accurate and reliable, and by the adoption of the method, the administrative relationships among the electric energy meters and the corresponding busbars can be recognized 100% accurately. Besides, operation is simple and convenient, efficiency is high, and after powering off, an operator only needs to copy and read powering off records and powering on records of the electric energy meters for one time with the hand-held meter reading machine. Furthermore, recognition rate is high, the administrative relationships among the electric energy meters and the busbars (transformers) which the electric energy meters belong to can be well recognized, and the problem that user-transformer relationships are confusing is completely solved.

Description

technical field [0001] The invention relates to a method for sorting out power transmission and distribution lines, in particular to a method for sorting out the relationship between transformers and electric energy meters. Background technique [0002] For a long time, due to various reasons such as the increase in electricity load and new users, the affiliation relationship between users (electric energy meters) under the distribution transformer and the original power supply transformer (busbar) has often changed. However, due to line crossing, buried lines, etc., it is difficult to update the affiliation information of transformers (busbars) and users (electric energy meters) in a timely manner. In addition, due to historical reasons, the affiliation information of many transformers (busbars) and users (electric energy meters) is missing or incorrect. [0003] Incorrect affiliation between transformers (busbars) and users (watt-hour meters) leads to low success rate of ...

Problems solved by technology

Since this method needs to be connected to the "stage area identification instrument" at the transformer (busbar) and the electric energy meter, the operation is troublesome and there are safety problems. very low

In addition, since the detection is a low-frequency signal, when there is interference or other reasons, it cannot be guaranteed to detect the low-frequency signal 100%, causing problems such as misjudgment or missed judgment.
