Problems solved by technology

[0005] At present, the sound level test of power transformers still adopts the conventional power transformer noise measurement method. It is extremely inconvenient and has the risk of electric shock by the measurement personnel to lift the microphone connector or stand at a high place with an escalator. Large volume, low work efficiency, and need the cooperation of multiple operators, etc.
At the same time, due to the long transmission cable of the detection device, it is difficult to collect and entangled together, the equipment is easily damaged and the detection efficiency is low

Abstract

The invention provides an auxiliary noise detection device for a power transformer, which is used for detecting the noise of the power transformer and comprises a base which is a hollow shell and is placed on the ground; a lifting rod suite which can realize the combination of a plurality of rod bodies with a lifting function, the bottom end of the lifting rod suite is arranged in the shell of the base, and the top end of the lifting rod suite extends out of the upper surface of the base; a noise detection module which is used for detecting and analyzing the noise of the power transformer; and a lifting power module which is used for providing power for lifting of the lifting rod suite and is arranged in the shell of the base. According to the invention, the workload of power transformer noise detection can be reduced, operators are reduced, the detection efficiency is improved, and the electric shock risk of handheld detection is eliminated.

Description

technical field [0001] The invention relates to the technical field of power equipment detection, in particular to an auxiliary power transformer noise detection device and an execution 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. In recent years, power transformers have increasingly appeared in residential areas and public places, and the noise of power transformers has gradually become a new environmental protection issue that people pay attention to. During the sampling inspection of power transformers, sound level tests and noise levels of detectors are required to determine whether they meet the requirements of relevant standards. [0003] Power transformer noise is generated by the vibration of the iron core, winding, oil tank and cooling device, and the size of the power transf...
