Problems solved by technology

The current method of melting ice is mostly DC short-circuit ice melting, which requires staff to lift the short-circuit cable for high-altitude installation. The current technology takes a lot of time to collect, release and fix the short-circuit cable, and the staff is prone to accidents. Fatigue, and the working environment is generally cold and slippery, and the length of working hours is inversely proportional to safety
Therefore, designing a device that can be short-circuited quickly can reduce the large amount of manpower, material and financial resources consumed in solving the widespread ice-melting operation of the line, improve the operation safety, operation quality and efficiency in severe weather, and solve the problem. There are technical problems of ice melting that are difficult to solve by relying on relatively complicated high-altitude operations and limited means of operation

Description

technical field [0001] The invention relates to the field of power transmission line ice melting technology, in particular to a shorting device for a portable ice melting device. Background technique [0002] Icing of transmission lines in winter is one of the major natural disasters of the power system. The consequences of accidents such as interruption of power supply and even disconnection of the power grid caused by icing are usually extremely serious, and the repair work is difficult and takes a long time. The current method of melting ice is mostly DC short-circuit ice melting, which requires staff to lift the short-circuit cable for high-altitude installation. The current technology takes a lot of time to collect, release and fix the short-circuit cable, and the staff is prone to accidents. In addition, the working environment is generally cold and slippery, and the length of working hours is inversely proportional to safety. Therefore, designing a device that can be...
