On-line monitoring system of high-altitude and high-voltage power transmission line

Abstract

The invention relates to the power transmission and transformation technology field, more particularly to an on-line monitoring system of a high-altitude and high-voltage power transmission line. The on-line monitoring system comprises: (1), an OPGW optical cable that is especially used by electric power and a broadband wireless MESH network based on an 802.11WLAN standard are employed for combination to construct a broadband transmission link; (2), an optical cable communication link based on a power transmission line OPGW is constructed; and (3), a wireless communication link is constructed. According to the on-line monitoring system of a high-altitude and high-voltage power transmission line in the invention, problems that a traditional line inspection mode wastes time and energy as well as plateau meteorology causes certain inconvenience for daily line maintenance and processing on emergent situations can be solved; therefore, a high definition on-site video of a random tower on a high-voltage power transmission line and data like local weather information can be returned to a headquarter in real-time, so that problems of a severe environment and difficult line patrol and the like can be effectively solved; moreover, the system has an active significance for further improving a safe operation level of a power grid.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation, in particular to an online monitoring system for high-altitude, high-voltage transmission lines. Background technique [0002] With the rapid advancement of the State Grid Corporation's "one strong and three excellent" modern power grid strategy, the use of scientific and technological means to improve the safe operation of the power grid has become an inevitable trend in the development of modern power grids. The traditional line inspection method is time-consuming and labor-intensive, especially in areas with harsh environments and inconvenient traffic along the overvoltage transmission lines in high-altitude areas. The situation has caused some inconvenience to the daily maintenance of the line and the handling of emergency situations. In the traditional way, when the temperature drops below -10°C, the energy storage capacity of the battery is greatly reduced, an...
