Abstract
The utility model discloses a kind of portable fault diagnosis devices for 10KV network distribution transformer, including acoustic sensor, acceleration transducer, NI high-speed data acquisition card, tablet computer and loudspeaker, acoustic sensor and acceleration transducer are connected to the data input pin of NI high-speed data acquisition card, the data output end of NI high-speed data acquisition card is connected to tablet computer, and tablet computer is connected with loudspeaker.The utility model is acquired the frequency spectrogram on signal to tablet computer and is handled by acoustic sensor, acceleration transducer, high-speed collection card, when being greater than given threshold, the broadcasting of failure sound is carried out by external loudspeaker, by the sound of broadcasting differentiate transformer whether normal operation, inside detects the failure sound of inside transformer with the presence or absence of failure by vibrating sensor and microphone, and differentiation is more accurate, and the personnel without experience can also operate, it is easy to operate, differentiate relatively reliable.
Description
Technical field
The utility model belongs to transformer fault monitoring device technical field, and in particular to one kind is used for 10KV distribution transformation
The portable fault diagnosis device of device.
Background technique
It is uniform buzz that transformer, which operates normally the sound issued, when there are shelf depreciations, electric arc for inside transformer
When the failures such as electric discharge, short circuit, different sound will be issued, by acquisition sound can to equipment inside with the presence or absence of failure into
Row differentiates that the fault diagnosis of 10kV network distribution transformer is taken on the transformer often by insulating bar at present, leaned against by human ear
Internal sound is listened then experience to be commented to analyze and determine internal fault on bar, for babe in the wood, it is difficult to judge
Transformer whether failure or judge inaccuracy.
Summary of the invention
The technical issues of the utility model solves is: providing a kind of portable fault diagnosis for 10KV network distribution transformer
Device, to solve above-mentioned problems of the prior art.
A kind of technical solution that the utility model is taken are as follows: portable fault diagnosis dress for 10KV network distribution transformer
Set, including acoustic sensor, acceleration transducer, NI high-speed data acquisition card, tablet computer and loudspeaker, acoustic sensor and
