Embodiment Construction

[0010] Below in conjunction with accompanying drawing, the present invention is further described

[0011] First purchase electric heaters, electric heating tubes, electric heating wires, electric heating wires, and electric heating bands, and then connect them in series with ventilation pipelines, and then fix them in parallel with high-voltage wires. Take electric heating tube as an example

[0012] The implementation is as follows:

[0013] First purchase the electric heating tube 1 and then connect it in series with the ventilation pipe 3, and then connect it in parallel to a section of high-voltage wire 2, so that when there is ice covering, the air flow becomes a hot air flow, and the hot air flows through the ventilation pipe 3, so that the ventilation pipe and the high-voltage wire 2 Simultaneous heating, (or leakage of hot air flow), in the form of conduction, radiation, and heat convection, melts the ice on the high-voltage wires and insulators.

Abstract

The invention relates to an ice-melting heater of a high-voltage transmission line, which is characterized in that an electrothermal heater (an electric heater, an electrothermal pipe, an electrothermal line, an electrothermal wire, an electrothermal tape and the like) is connected with a segment of high-voltage transmission line in parallel. The electrothermal heater is installed on a pipeline, the pipeline is laid on a lead, and a cold airflow passes through the pipeline and flows through the heater, so that the temperature of the airflow is raised, the covered ice on the pipeline and the lead of the high-voltage transmission line is melted in the modes of conduction, radiation and heat convection, and the covered ice on an insulator is melted.

Description

technical field [0001] The invention relates to a high-voltage transmission line ice-melting heater, which belongs to the field of ice melting. Background technique [0002] The invention discloses a method for melting ice of a high-voltage transmission line, which belongs to the field of ice melting. [0003] 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. [0004] The invention is a high-voltage transmission line ice-melting heater, which shows its superiority and can melt ice for a long time. Contents of the invention [0005] The invention is a high-voltage transmission line ice-melting heater, which is characterized in that the electric heater (electric heater, electric heating tube, electric heating wire, electric heatin...
