Abstract

The invention discloses a transformer partial discharge detection device and method. A box body and a box cover of a supporting assembly are rotationally connected, a rotating rod is rotationally arranged on one side of the box body, a plurality of folding rods are sequentially connected with the rotating rod, the folding rods comprise a first rod and a second rod, a first rotating shaft of the first rod is placed in a second sliding groove of the second rod for connection, a second clamping column of the second rod can be matched with a first clamping groove of the first rod to fix the firstrod and the second rod, a detection head of the detection assembly is arranged on the folding rod, the detector and the display screen are located in the box body and the box cover respectively, and ahanging belt and a supporting plate of the fixing assembly are arranged on the box body. According to the invention, the box body and a human body are fixed through the hanging belt and the supporting plate; the folding rod is pulled out based on the detection height, and the second clamping column and the first clamping groove are combined; the rotating rod is rotated to enable the detection head to reach a detection position, and the detection head is used for detection; and the detector processes detection data and displays the detection data through the display, so that the detection range can be enlarged.

Description

technical field [0001] The invention relates to the field of discharge detection devices, in particular to a transformer partial discharge detection device and method. Background technique [0002] A power transformer is a static electrical device that is used to change an AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values. When the power transformer equipment produces partial discharge, it will generate electromagnetic waves, and when the electromagnetic waves propagate outward, it will generate a transient ground voltage signal. The magnitude of this signal is directly related to the intensity of partial discharge and the distance of the discharge point. A special detector can be used for detection, which is a partial discharge detector. [0003] When using a partial discharge detector to detect power transformers, it is often necessary for the operator to hold the detection probe close to the surfac...
