Embodiment Construction

[0008] Below in conjunction with accompanying drawing, the present invention is further described

[0009] Purchase compressed air equipment 1, vent pipe 2, and electric heater 3, and then fix the vent pipe on the high-voltage wire 4 respectively.

[0010] The implementation is as follows:

[0011] Lay the ventilation pipe 2 side by side and fix it on the high-voltage wire 4, install the compressor 1, and install the electric heater 3 on the airflow path between the ventilation pipe 2 and the compressor 1, so that when there is ice, start the compressor 1 , the electric heater 3 on the airflow path makes the airflow become a hot airflow, and the hot airflow flows through the ventilation pipe 2, so that the ventilation pipe and the high-voltage wire 4 are heated at the same time, and the high-voltage transmission line wire is heated by conduction, radiation, and heat convection. The icing on the insulator 5 is melted, and the icing on the insulator 5 is melted.

Abstract

The invention relates to a hot airflow type ice melting method of a high-voltage transmission line, which is characterized in that a vent pipe is laid on a lead, and a hot airflow passes through the pipe, so that the covered ice on the lead, an insulator and the pipe is melted. The hot airflow type ice melting method is characterized in that compressed-air equipment, the vent pipe and an electrothermal heater are provided in the method, wherein the vent pipe and the lead of the high-voltage transmission line are parallel and are fixed on the lead, air is compressed by the compressed-air equipment, the air is heated by the heater and flows through the vent pipe, the hot airflow flows through the vent pipe, and the high-voltage lead is heated, so that the covered ice on the high-voltage lead and the vent pipe is melted; and the airflow leaks out of a hot airflow pipe or is used for heating the surrounding air below the insulator, so that the covered ice on the insulator is melted to realize whole-line and whole-network ice melting.

Description

technical field [0001] The invention relates to a method for melting ice of a high-voltage transmission line, which belongs to the field of ice melting. Background technique [0002] A method for melting ice of a high-voltage transmission line, which is a blank in the field of ice melting. Now there is a method of melting ice called short-circuit method, which is to short-circuit the two-phase lines, make the wires short-circuit and generate heat, and melt the ice. When the ice is melted, the power will be cut off, which will affect the life of the line and the time will be short. [0003] The invention is a method for melting ice of a high-voltage transmission line, which shows its superiority and can melt ice on the whole line and the whole network for a long time. Contents of the invention [0004] The invention is a hot air flow ice-melting method for a high-voltage transmission line, which is characterized in that a ventilation pipe is laid on the wire, and the hot ...
