An overhead line icing monitoring device

Abstract

The invention relates to the technical field of icing detection on overhead lines, in particular to an icing monitoring device for overhead lines, which includes an upper fixing mechanism, a sample mechanism and a lifting mechanism. The upper fixing mechanism includes an upper mounting assembly for detachable connection with a pole , the installation component is fixed with an upper fixture; the sample mechanism includes a sample rack and a sample line detachably connected to the sample rack; the lifting mechanism is arranged on the fixer and is used to control the movement of the sample rack. In specific use, install the upper fixing mechanism on the pole at the point to be tested. When monitoring, first install the sample line on the sample rack, then lift the sample rack close to the overhead line through the lifting mechanism, and finally observe the line to be tested and the sample. The diameter of the line is different, so as to obtain the icing situation of the overhead line; the invention has poles suitable for various types, the monitoring results are not easily interfered by electromagnetic signals, the monitoring accuracy is high, the stability is good, and it is not affected by environmental factors such as terrain and climate. Features with less impact.

Description

technical field [0001] The invention relates to the technical field of ice coating detection for overhead lines, in particular to an ice coating monitoring device for overhead lines. Background technique [0002] The normal supply of electricity is related to the normal production of the people and people's lives, and is an important issue of people's livelihood. In recent years, due to the influence of macro-climate and micro-meteorological conditions in my country, ice disaster accidents have occurred frequently, causing huge economic losses. Under certain meteorological conditions, ice crystals accumulate around the wires on the power transmission line. Icing will increase the load on the wires and towers. At the same time, the shape of the circular cross-section of the wires will be changed, and the windward area will be enlarged. Events such as network, torsion, wire disconnection, and pole down, resulting in large-scale power outages. In 2008, a large-scale continuou...
