The invention discloses a supporting insulator type high voltage induction sensor. The supporting insulator type high voltage induction sensor is fixed in high-voltage electrical equipment, and comprises an insulator, an upper flange is arranged at the upper end of the insulator, a lower flange is arranged at the lower end of the insulator, a printed circuit board is arranged in the insulator, a shielding cover is arranged on the face, opposite to the lower flange, of the printed circuit board, and the printed circuit board and the shielding cover are fixed with the lower flange through a connecting piece. The other face of the printed circuit board is opposite to a high-voltage electrified body, and a signal line for outputting voltage signals is further arranged on the other face of the printed circuit board. Due to the fact that the printed circuit board is adopted to replace two pieces of existing copper foil to induct electric field signals, industrial production of the sensor can be achieved, and the production efficiency of the sensor is greatly improved. Meanwhile, due to the fact that the high-voltage electrified body can be fixed to the upper flange in the insulator, the high-voltage electrified body can be fixed conveniently, the distance between the high-voltage electrified body and the printed circuit board is fixed, the electric field signals in the high-voltage electrified body can be detected accurately and reliably, and wrong instructions and misoperations can be avoided.
