Device for detecting winding humidified insulation of synchronous phase modifier

The invention discloses a device for detecting winding humidified insulation of a synchronous phase modifier. The device comprises a plurality of humidity sensors, a current amplifier and a display, wherein the plurality of humidity sensors are arranged at winding insulation portions of the synchronous phase modifier respectively, and are used for detecting whether the winding insulation of the synchronous phase modifier is humidified; the current amplifier is connected with the plurality of humidity sensors, and is used for amplifying current signals; and the display is connected with the current amplifier, and is used for displaying the amplified current signals. When the winding insulation of the synchronous phase modifier is humidified, the current is displayed on the display, the winding humidified insulation condition can be detected without disassembling the synchronous phase modifier, the convenience of detection is improved, the humidified condition of the winding insulation is determined according t
