Abstract

The present invention relates to a method for automatically identifying an identity of an instrument transformer, which is realized in the way that a terminal reads storage data in an electronic tag arranged on the instrument transformer. Reading of the storage data comprises the steps as follows: the terminal updates a built-in database; the terminal discovers the electronic tag; the terminal reads data in a storage area of the electronic tag; the terminal decrypts the read data and judges validity of the electronic tag; the terminal writes this reading record into a specific storage area of the electronic tag; and the terminal finishes identification. The method can automatically identify the identity of an electric instrument transformer, and can automatically judge the validity of the corresponding instrument transformer in combination with a database. At the same time, the electronic tag cooperating with a coating material has an instrument transformer nameplate function, thus the electronic tag can completely replace an original nameplate.

Description

Technical field:

[0001] The invention relates to a method for identifying the identity of a transformer, more particularly to a method for automatically identifying the identity of a transformer. Background technique:

[0002] Instrument transformer, also known as instrument transformer, is a general term for current transformer and voltage transformer. It can change high voltage into low voltage and high current into small current for measurement or protection system. Its function is mainly to convert high voltage or high current into standard low voltage (100V) or standard small current (5A or 1A, both refer to rated value) in proportion, so as to realize the standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment. change. At the same time, the transformer can also be used to isolate the high-voltage system to ensure the safety of people and equipment. With the rapid construction and development of the power gri...
