Problems solved by technology

That is, the heating efficiency of the steel core is low, a large current is required, and the power is turned on for a long time. If the control fails, the heating temperature of the steel core (especially the joint part) will be too high, or after the auxiliary heating resistor is energized, if the control fails, the resistance temperature will be too high. High, easy to damage the insulation sheath, steel core and aluminum strand
Therefore, the scope of application is limited and cannot be promoted

Embodiment Construction

[0036] 1. Overall

[0037] like figure 1 , the invention includes an auxiliary heating wire (1) made of conductive polyester fiber capable of generating low-temperature infrared heat energy, a high thermal conductivity insulating sheath (2), and a steel hinge wire (3).

[0038] The auxiliary heating wire (1) is made of a high thermal conductivity insulating material as a sheath (2), insulated from the steel hinge wire (3), and twisted around the center of the steel hinge wire (3) to become one.

[0039] 2. Functional parts

[0040] 1. Auxiliary heating wire (1) is made of conductive polyester fiber that can generate low-temperature infrared heat energy. According to the needs of different wire diameters and calorific value, multiple fibers can be twisted together, and then high thermal conductivity insulating material can be used as The sheath (2) generates infrared heat energy after electrification.

[0041] 2. The high thermal conductivity insulating sheath (2) is made of...

Abstract

A novel auxiliary heating lead which is made from a conducting polyester fiber which can generate low-temperature infrared heat and an ordinary ground wire are combined, and a high-heat conducting insulating material serves as a protecting sleeve of the auxiliary heating lead and is interwoven in the center of a stranded steel wire to form a whole. In the weather of low-temperature freezing rain, ice is probably coated on the ground wire, or when the coated ice is required to be automatically removed, an auxiliary power supply is loaded to the auxiliary heating lead, voltage difference is generated between the auxiliary heating lead and the stranded steel wire, and after a switch K is turned off, the auxiliary heating lead generates the low-temperature infrared heat, the temperature of the stranded steel wire is increased, and the aim of preventing or automatically removing ice is fulfilled.

Description

technical field [0001] The invention relates to a lightning protection wire and a high-voltage transmission wire thereof, in particular to a novel low-temperature infrared auxiliary heating and automatic deicing lightning protection wire. Background technique [0002] In recent years, in response to the phenomenon of wire galloping, disconnection and tower collapse caused by severe icing of high-voltage transmission lines in low-temperature freezing rain, some scientific research institutions, institutions of higher learning and power companies at home and abroad have proposed a variety of line deicing methods, but none Deicing method specifically for lightning conductors. In summary, there are three main categories. [0003] 1. Mechanical deicing method. It is to use robots to work back and forth on the high-voltage transmission line, because the technology is not yet mature, and the high-voltage transmission line needs to be powered off during the operation, resulting in...
