On-site Measuring Device for Wind Noise of Transmission Lines

Abstract

The invention discloses a field measurement device for wind noise of a power transmission line. An ultrasonic anemoscope is mounted on a roof below the power transmission line; a sound sensor, a real-time dynamic data acquisition system, a computer host, a real-time data processing system and a wireless data transmission module are mounted in a room; the acquisition system is used for acquiring real-time data of the ultrasonic anemoscope and the sound sensor; the computer host is used for storing the real-time data of the acquisition system; the real-time data processing system of the computer host is used for processing the real-time data of the acquisition system, obtaining wind noise statistical information of the ultrasonic anemoscope and the sound sensor, publishing the wind noise statistical information to a remote database station through the wireless data transmission module and a 4G network and reading the wind noise statistical information of the remote database station through a remote client access system. According to the field measurement device, the wind speed and sound at the installation site can be ceaselessly tested all weather, so that the real-time uploading and remote access of the wind noise statistical information are realized, and the sound characteristics and wind speed conditions during the occurrence of the wind noise of the power transmission line are extracted.

Description

technical field [0001] The invention relates to a noise measurement device, in particular to an on-site measurement device for wind noise of transmission lines. Background technique [0002] With the rapid development of power systems, overhead transmission lines have been widely used due to their advantages of simple construction, easy maintenance, and adaptability to various terrains. With the improvement of voltage levels and the development of urbanization, lines will inevitably cross densely populated areas, and environmental problems such as wind noise and corona noise caused by transmission lines have increasingly become the object of complaints. At present, my country's codes only conduct a series of studies on corona noise, and there is almost no research on wind noise from transmission lines. [0003] The wind noise of the transmission line is mainly generated by the dipole sound source formed by the vortex shedding of the wind around the surface of the transmissi...
