The invention relates to an intelligent ice melting device for an electric system. The device comprises a high voltage power supply system, an AC / DC power converting unit, an ice melting power supply control system, an input bus bar, an output bus bar and a cooling system. The high voltage power supply system changes high voltage of 3,300V into direct current voltage which is suitable for ice melting by a power network, the direct current voltage is sent to the AC / DC power converting unit by the input bus bar, output after rectification by the AC / DC power converting unit and sent to an ice melting load by the output bus bar, and the ice melting device is cooled by the cooling system; the AC / DC power converting unit is controlled by the ice melting power supply control system to ensure that the output voltage and the output current are adjusted continuously and respectively between 0 and 4,500V and between 0 and 12,000A, and the direct current supply of one positive and two negatives or two positives and one negative is output. The device has the advantages of high speed of removing ice or snow on power transmission lines, manpower saving and high safety.
Description
technical field [0001] The invention relates to a power grid line maintenance device, in particular to a power system intelligent ice-melting device for removing ice and snow from transmission lines in winter. Background technique [0002] Recently, ice and snow disasters have occurred successively in southern my country, causing the national grid transmission lines to freeze and affecting the power supply of the power system. At present, the deicing technology mainly relies on manual and semi-mechanical methods. The work of removing ice and snow on transmission lines basically depends on people climbing the iron tower, knocking on the ice and snow, and shaking them to the ground. Its efficiency is low, and very prone to personal safety accidents. In severe weather conditions, the difficulty and danger of deicing are very high, which poses a serious threat to the life safety of deicing workers. Contents of the invention [0003] The purpose of the present invention is to...
