Power transformer multipath automatic on-site detection system and method based on Internet of Things

Abstract

The invention relates to a power transformer multipath automatic on-site detection system and method based on the Internet of Things. The method comprises the following steps: a detected transformer is connected to a field detection terminal; basic parameters of the detected transformer are identified; an electronic fence is temporarily built, and a safety signal is sent to the field control center after the wireless electronic access control is closed; the field control center relieves test locking and sends a test confirmation instruction to the electronic key; after an operator selects agreement confirmation test, an agreement signal is sent to the field control center; the field control center sends a test starting instruction to the field detection terminal; the field detection terminal starts testing work; and after the test is completed, the field control center intelligently judges the test data to obtain a test result. According to the invention, wireless networking is carried out on all equipment, so that an operator absolutely keeps a safe distance from a test site in a detection process; meanwhile, distributed networking and synchronous operation of a plurality of field detection terminals can be realized, so that the field detection efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of electric power detection, and in particular relates to a multi-channel automatic on-site detection system and method for power transformers based on the Internet of Things. Background technique [0002] At present, for the detection of power transformer metering / measurement / protection windings, the instruments commonly used at home and abroad include: current transformer field tester, electromagnetic voltage transformer field tester, capacitive voltage transformer field tester, protection Transformer winding excitation characteristic analyzer and so on. These instruments are not only expensive to purchase, but also a single instrument performs a single-circuit test on a single transformer under test. The staff can only use a certain type of instrument on site, and connect to a certain winding of a certain transformer at a time, and then manually input the transformer nameplate parameters on the field tes...

Problems solved by technology

[0004] With the extension of the detection time, the risk of multi-department cross-operation on site will inevitably increase, and it will be more vulnerable to the influence of the weather and cause invalid round-trips

With the rapid development of the economy and the acceleration of urbanization, the scale of the power grid has also expanded. The contradiction of the shortage of inspection personnel under the traditional inspection mode has become increasingly prominent. The existing manpower and material resources are difficult to meet the work needs of the equipment. transformation
