Description

technical field [0001] The present invention relates to an electric power monitoring device, more specifically to a wire vertical arc monitoring device. Not affected by environmental factors, with high precision, it can carry out remote automatic monitoring of wire sag. Background technique [0002] Transmission lines are an important part of the power system. At present, my country's power shortage is serious. The transmission capacity of transmission lines in many areas cannot meet the growing demand for electricity, and they are forced to limit power. According to the statistics of the State Grid Corporation of my country, in the first half of 2010, there were a total of 757,000 power cuts in China, and the power loss was 19.453 billion kWh. This not only seriously affected people's daily production and life, but also caused immeasurable economic losses. For this reason, in order to meet the demand for electricity in some areas, the amount of wire transmission is increa...
