Description
Technical field
The present invention relates to the measuring devices of noise, more particularly, to a kind of field measurement device of power transmission line wind noise.
Background technique
With the high speed development of electric system, overhead transmission line because have easy construction, for ease of maintenaince, adapt to a variety ofly
The advantage of shape and be widely applied.Along with the development of raising and the urbanization of voltage class, route can inevitably across
More populated area has been had become complained pair by environmental problem such as wind noise and corona noise that transmission line of electricity generates
As.China's specification has carried out series of studies just for corona noise at present, for power transmission line wind noise almost without research.
Power transmission line wind noise is mainly to be generated by wind around the de- sound source of the dipole formed in power transmission line surface whirlpool, with power transmission line
Material and vibration characteristics are unrelated, and related with the external surface shape of power transmission line, diameter and wind speed and direction etc..Do not have both at home and abroad at present
Field measurement research was carried out for power transmission line wind noise.In China at present to actual measurement regulation (the Q/GDW 550- of corona noise
2010 transmission lines of electricity reduce audible noise design and construction guideline) in, it is desirable that " wind speed should stop measuring when being more than 5.5m/s ",
However power transmission line wind noise only occurs in strong wind atmosphere (at least 10m/s or more).Therefore exploitation power transmission line wind is highly desirable to make an uproar
The field measurement device of sound.
Summary of the invention
The purpose of the present invention is to provide a kind of field measurement devices of power transmission line wind noise, can round-the-clock test free of discontinuities
The wind speed and sound of erecting bed realize the real-time upload and remote access of wind noise statistical information, extract power transmission line wind and make an uproar
Sound characteristic and wind friction velocity when sound occurs.
The technical solution adopted by the present invention to solve the technical problems is:
The present invention is immediately below power transmission line or the room top layout of side-lower has ultrasonic wind velocity indicator；Portion in the room

The real time data of data collection system obtains the wind noise statistical information of ultrasonic wind velocity indicator and sound transducer, by wireless
Data transmission module and 4G Web Publishing read remote data base by remote client access system to remote data base website
The wind noise statistical information of website.
The mounting height of the ultrasonic wind velocity indicator should be higher than that 1m or more at the top of room.
The sound transducer sky is lifted on room inner top surface, in 1m or more with a distance from each side in room.
The invention has the advantages that:
The present invention can realize the reality of wind noise statistical information with the wind speed and sound of round-the-clock test erecting bed free of discontinuities
Sound characteristic and wind friction velocity when power transmission line wind noise occurs are extracted in Shi Shangchuan and remote access.
