Embodiment
[0039] like figure 1 and figure 2As shown, an overhead line icing monitoring device includes an upper fixing mechanism 100 and a lower fixing mechanism 200 detachably connected to the pole, and a lifting mechanism 300 is installed between the upper fixing mechanism 100 and the lower fixing mechanism 200. A sample mechanism is provided on the lifting mechanism 300, and the sample mechanism includes a sample rack 400 and a sample line 500 detachably installed on the sample rack 400, where the sample line 500 is a cable. During specific use, the upper fixing mechanism 100 and the lower fixing mechanism 200 are installed on the electric poles at the point to be measured. The mechanism 300 lifts the sample rack 400 close to the overhead line, and finally observes the diameter difference between the line to be tested and the sample line 500, so as to obtain the icing condition of the overhead line. The detection of the icing condition of the overhead line by this device has high p...

The invention relates to the technical field of overhead line icing detection, in particular to an overhead line icing monitoring device which comprises an upper fixing mechanism, a sample mechanism and a lifting mechanism, the upper fixing mechanism comprises an upper mounting assembly used for being detachably connected with an electric pole, and the mounting assembly is fixedly provided with anupper fixing piece; the sample mechanism comprises a sample frame and a sample line detachably connected with the sample frame; and the lifting mechanism is arranged on the fixed part and is used forcontrolling the sample frame to move. During specific use, the upper fixing mechanism is installed on an electric pole of a to-be-measured point, during monitoring, the sample line is firstly installed on the sample frame, then the sample frame is lifted to be close to the overhead line through the lifting mechanism, and finally the diameter difference between the to-be-measured line and the sample line is observed, so that the icing condition of the overhead line is obtained. The device has the characteristics that the method is suitable for various types of electric poles, the monitoring result is not easily interfered by electromagnetic signals, the monitoring precision is high, the stability is good, and the influence of environmental factors such as terrain and climate is small.
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...
