Finally, the display bottle 10, the separation fiber 11 and the anhydrous copper sulfate particles 12 form a color developing device to monitor the working environment in the shell 2, so that the working state of the dry-type transformer can be reminded in advance when maintenance personnel perform routine maintenance.
The foregoing is only a preferred embodiment of the present invention; the scope of the invention is not limited thereto. Any person skilled in the art should be able to cover the technical scope of the present invention by equivalent or modified solutions and modifications within the technical scope of the present invention.
