Abstract

The invention belongs to the technical field of discharge fault detection devices, in particular to modeling and identification of a discharge fault voiceprint spectrum, including a handle, a placement slot, a limit clip and a receiver, the placement slot is set inside the handle, and the limit The clip is fixedly connected to the inner wall of the placement groove, and the receiver is clamped inside the limiting clip. There are two groups of the limiting clips, which are symmetrically arranged inside the placement groove; the beneficial effect of the present invention is that by setting the first fixing clamp, the second fixing clip, bolts and knobs, when the user needs to fix the first support plate and the second support plate, the user first takes the device out of the tool box, and then puts the first support plate carrying the limit ring Lap the upper end of the gasket, then overlap the first fixing clip on the upper end of the second support plate, and at the same time, snap the second fixing clip on the lower surface of the first support plate, and then turn the knob to make the first support The board is fixed with the second support board, and then the receiver is snapped into the limit clip.

Description

technical field [0001] The invention relates to the technical field of discharge fault detection devices, in particular to a discharge fault detection device. Background technique [0002] Partial discharge measurement is an important means of judging the insulation strength of high-voltage power equipment. Non-contact ultrasonic measurement method is an effective method of partial discharge measurement. Collected by the type ultrasonic sensor, the amplitude data and characteristic waveform are displayed after analysis and processing by the partial discharge detector. [0003] At present, there are many partial discharge detectors on the market. The performance of the instruments produced by different manufacturers is not uniform, and the amplitude data and characteristic waveforms are inconsistent. Therefore, a reliable and stable calibration device is needed for calibration. However, the calibration devices on the existing market are not Easy to adjust, resulting in low c...
