Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to a power transformer detection system. Background Art

[0002] In the power system, power transformers are often used. Their function is to convert the high-voltage signal transmitted by the power grid into 380V (three-phase 220V mains signal). The 380V signal output of most transformers is output through 4 copper bars, 3 of which correspond to 3-phase 220V output, and 1 copper bar is the neutral line output. In actual applications, each factory will install one or more transformers, and generally the electric meter is connected to the rear end of the transformer. The user's electricity consumption is measured according to the electric meter after the transformer. If someone steals electricity before the electric meter, it cannot be detected, and this method cannot remotely monitor the transformer signal problem. In addition, a current transformer and a voltage transformer are installed on the copper bar of the transformer, and then a collection device is connected to each transformer, and then connected to a remote computer by wire, and then uploaded to the server through the computer. This method has a complex and large structure, is inconvenient to install, and is not practical.
