Perimeter protection system for overhead line

Abstract

The invention relates to a perimeter protection system for an overhead line. The system comprises a warning device and a cloud platform, wherein the warning device is composed of a laser warning module, a voice warning module and a main control module, and the warning device is installed on an iron tower frame of the overhead line and is used for playing a role in warning on site; and the cloud platform is deployed on a power supply bureau intranet server and is used for carrying out comprehensive management on the warning device, and the cloud platform is in network connection with the warning device. The whole warning device is installed on an iron stand of the overhead line, so that hot-line work is avoided, and the safety is high. The warning device adopts a visible laser to form an accurate and obvious warning area, and light beams cover the whole lead, so that the warning area is wide; the laser is high in brightness and is not easily interfered by sunlight; the identifiability of the laser is improved through shaping and beam expanding of the laser; long-distance accurate transmission of sound can be realized by a directional loudspeaker, so that noise pollution is avoided; and a multifunctional cloud platform is additionally arranged, so that unified management is realized, and the warning effect of the warning device is more flexible and diverse.

Description

technical field [0001] The present application relates to the technical field of perimeter protection for electric power overhead lines, in particular to a perimeter protection system for overhead lines. Background technique [0002] With the rapid development of economic reform, electricity has become an inseparable part of our life, which facilitates our life and improves the happiness index of people's life. So, in today's era when electricity is indispensable, how to ensure the safety and reliability of power supply has become a crucial issue. In the entire power supply system, ensuring the normal transmission of power on overhead transmission lines has become a very important link. Due to the increasing number of engineering constructions, many construction sites are located in the corridors of multiple overhead transmission lines, which pose a security threat to the transmission lines. Therefore, necessary perimeter protective devices are needed during the daily main...

Problems solved by technology

Since the construction site is an outdoor environment, the warning device will be disturbed by sunlight and the noise of the on-site mechanical construction, resulting in a small effective warning distance, so that the on-site engineers cannot observe the warning light and hear the sound of the alarm, and cannot reach The expected warning effect, and the warning balls and warning signs traditionally installed on the wires require live work or power outage work during installation, the operation cost, risk and complexity are high, and disassembly and assembly are inconvenient

Although some high-power voice announcers increase the warning distance, they use horn speakers, and the sound can be transmitted in all directions, which will cause noise pollution and affect the daily life of surrounding residents, and the current warning devices lack uniformity. effective management
