Arrangement introduced in partial discharge sensor applied to transformer bushings

摘要

Arrangement introduced in partial discharge sensor applied to transformer bushings.The present invention patent refers to a provision introduced in the sensor of partial discharges to allow their attachment and better use / application in bushings of power transformers, in such a way that does not present a risk for both the sensor and the electrical system, and enabling The uptake of partial discharges (PDS) with high sensitivity and shielding of interfering signals.This is a specific packaging mechanical circular tubular (11) closed at its ends by a sleeve (39) and containing internally a shielding metal (9) to block interfering signals, so that the said mechanical packing (11) accommodates internally features These components of the sensor (1), allowing the fixation of said sensor (1) around the bushing (17).Externo.
