Problems solved by technology
[0003] However, due to my country's vast territory, spanning multiple latitudes and longitudes, and spanning five climatic zones from south to north: tropical, subtropical, warm temperate, intermediate temperate, and cold temperate, ADSS icing rarely occurs except in the tropics. The ADSS optical cable in the climate zone is affected by different degrees of icing every year, which seriously leads to broken cores or even broken cables, resulting in information interruption, road obstruction and other problems
Most of the existing optical cable melting methods are applied to OPGW, and the degree of promotion is not strong. Since ADSS is a fully insulated non-metallic optical cable, it cannot add a metal tube as a heating conductor like OPGW. Therefore, there is no reliable solution for ADSS so far. Program

The invention provides a novel ADSS anti-icing method which needs to provide an anti-icing all-dielectric self-supporting optical cable, and comprises the following steps: S1, erecting an optical cable on a power transmission line; s2, hanging a power supply measurement and control device beside a connection box, leading out a zero line and the live line of the carbon fiber net layer through the connection box, and connecting the zero line and the live line into the power supply measurement and control device, thereby supplying power for heating; s3, connecting to a power supply measurement and control device through a temperature measurement optical fiber so as to set a start-stop temperature range interval; s4, when the optical cable is coated with ice, starting a power supply measurement and control device, supplying power to the carbon fiber net layer, and rapidly generating high heat by using the high resistance characteristic of carbon fibers to realize ice melting of the optical cable; s5, when ice melting is completed, automatically turning off the power supply measurement and control device, and stopping heating; according to the invention, the icing condition of the ADSS in the low-temperature season can be prevented and solved.
Description
technical field [0001] The invention relates to the technical field of cables and wires, in particular to a novel ADSS anti-icing method. Background technique [0002] With the rapid development of the power system, the power communication network, as the basis of the smart grid and the power Internet of Things, is an important guarantee for the safe, reliable, stable, efficient and economical operation of the "two networks". At present, the communication network frame of the State Grid is mainly based on optical fiber, especially the main line is based on optical fiber communication. The ADSS optical cable is a unique optical cable for electric power. Because of its self-supporting, light weight, small diameter, and full insulation characteristics, it is widely used in optical cable lines of various voltage levels from 10kV to 500kV. [0003] However, due to my country's vast territory, spanning multiple latitudes and longitudes, and spanning five climatic zones from south...
