The invention discloses a signal regulation and protection device for a partial discharge ultra-high-frequency sensor. The device includes an induced voltage protection module, a radio frequency module, an overvoltage pulse absorption module, a first capacitor, and a radio frequency interference suppression module. The induced voltage protection module removes induced voltage to guarantee the safety of backend personnel and an acquisition device. The overvoltage pulse absorption module reduces the high-voltage pulse signals of a partial discharge ultra-high-frequency sensor. The radio frequency interference suppression module suppresses the signal noise of the partial discharge ultra-high-frequency sensor, conditions and protects the whole circuit, makes the circuit no longer affected by noise, and greatly reduces the safety risks.

Signal regulation and protection device and method for partial discharge ultra-high-frequency sensor

The utility model discloses a signal conditioning protection device of partial discharge superfrequency sensor, the device includes: module, first electric capacity, radio frequency interference inhibiting module are absorbed in induced voltage protective film piece, radio frequency module, excessive pressure pulse. Get rid of induced voltage through the induced voltage protective film piece, ensure rear end personnel and collection system's safety, absorb the fast effectual high -voltage pulse signal who reduces partial discharge superfrequency sensor of mould through pressing the pulse, useradio frequency interference to restrain the fast effectual noise that has restrained the signal of partial discharge superfrequency sensor of mould, played the effect of taking care of and protectingto whole circuit, make its potential safety hazard that has no longer received noise and very big reduction.
