The invention discloses an ultrasonic wire deicing device and a method thereof. The ultrasonic wire deicing device comprises a tension spring, a hitch ring, an insulating sleeve, two deicing tong handles, a rivet, bolts, an ultrasonic generator driven by a direct-current source, two deicing tong heads and ultrasonic acoustic systems. The deicing tong handles are connected with the deicing tong heads to form tong bodies, and two tong bodies are connected through the rivet; the right ends of the two deicing tong handles are connected through the tension spring and the hitch ring; the left ends of the two deicing tong heads are respectively provided with one ultrasonic acoustic system; each ultrasonic acoustic system comprises an electrode, a sandwich piezoelectric transducer, an amplitude transformer, a flange disc, a toolhead, a first bolt and a second bolt; the sandwich piezoelectric transducers are connected with the amplitude transformers through the second bolts; the amplitude transformers are connected with the toolheads through the first bolts; the sandwich piezoelectric transducers are connected with the ultrasonic generator through the electrodes; and the two amplitude transformers of the two ultrasonic acoustic systems are connected with the left ends of the two deicing tong heads through the bolts. The ultrasonic wire deicing device is good in deicing effect, small in energy consumption, simple and convenient in usage, low in cost and long in service life and is pollution-free.
Description
technical field [0001] The invention belongs to the field of deicing power transmission lines, and in particular relates to an ultrasonic deicing device for electric wires and a method thereof. Background technique [0002] In rainy, freezing and snowy weather, overhead transmission lines often freeze. The icing of overhead transmission lines will lead to accidents such as wire galloping, ice flash tripping, disconnection, falling poles (or towers) and communication interruptions. [0003] Ice damage accidents of various transmission lines have occurred thousands of times in my country. Operation experience shows that severe icing has endangered the safe operation of 500kV and even 1000kV transmission lines. In the southern part of my country, in severe winter and early spring, especially in the Guizhou Plateau, Sichuan-Shaanxi area, and the two lakes, rime and rain often occur, causing overhead power transmission lines to be covered with ice, causing damage to the power sy...
