The invention relates to a power equipment for an abnormality detecting device, with the advantages of easily reconstructing the engineering in the site, low cost and high S/N rate. The power equipment of a high voltage conductor which is supported inside a closed container through an insulator is provided with a first internal abnormality detecting device. The first internal abnormality detecting device comprises a first connection pipe arranged on the enclosed container,a first antenna holding pipe which holds the first antenna inside, and a first signal detecting circuit which is connectedwith the first antenna and is used for detecting the electromagnetic wave signal when any abnormality has occurred within the enclosed container.
