Apparatus for finding and processing partial discharge in power equipments

Partial discharge detection and processing unit of the power device according to the present invention, there is provided inside the power unit, but detecting a partial discharge caused outside of the inside of the operation of the power unit, and the electromagnetic wave signal represented by the partial discharge electromagnetic wave composite sensor for detecting both the sound wave signal represented by a sound wave; It is connected to a composite sensor and an electrical transient voltage protector for removing an excess voltage of the partial discharge flowing into the composite sensor; Filter and amplifier that is connected to said composite sensor and electrically, to filter and amplify the electromagnetic signals and acoustic signals of the PD detected by the composite sensor; Filter and a signal is connected to the amplifier and the electrical and converts the vibration signal Castle filtered and amplified by a filter and amplifier to the pulse-like signal shaper; Is connected to a signal shaper and electrically, a signal processor that receives the output signal from the signal shaper performs the operation algorithm for estimating the pattern and location of the partial discharge from the other hand, the signal to determine whether the signal is noise; And it is connected to the signal processor and electrically, and is for displaying the result of executing in a signal processor with visible hand comprises a display device and a network for transmitting the external where it is needed in. According to the present invention, and detecting a partial discharge generated in the power unit to the composite sensor for detecting the ultrasonic wave and electromagnetic wave, and remove the noise by processing the detection signal associated, it generated location of the partial discharge, the type of the defect and the risk until it can be analyzed.
