ADSS (all dielectric self supporting optic fiber cable) typhoon resistance estimation method at coastal region

Abstract

An ADSS (all dielectric self supporting optic fiber cable) typhoon resistance estimation method at a coastal region comprises following steps of S1, the nonoccurrence probability of an ADSS fault is calculated with a formula: P=A*sigma (X1, X2, X3...); A=A1*A2*...*An; in the formula, P is nonoccurrence probability of the ADSS fault and is in a hundred mark system; an ADSS nonoccurrence fault estimation coefficient is represented, a nonoccurrence fault estimation coefficient of estimation objects is represented by An, if an occurrence fault is non-maintainable or directly affects typhoon resistance, An is equal to 0, if the occurrence is maintainable or capable of recovering typhoon resistance, An is equal to 1; X1, X2, X3 ... respectively represent the weights of the occurrence fault probabilities of the estimation objects; the estimation objects comprise an ADSS self fault, an ADSS electrified corrosion state, an ADSS optical fiber attenuation state, an ADSS design standard application status quo, an ADSS sag state, applicable status quo of matched tools and engineering acceptance quality. The method promotes the application research of the ADSS in a typhoon environment, solves the problem existing in the application, and has an important significance in safe operation and development of power communication networks.

Description

technical field [0001] The invention relates to a method for evaluating the anti-typhoon ability of an ADSS in a coastal area. Background technique [0002] All Dielectric Self-Supporting Optical Fiber Cable (ADSS for short) is a non-metallic optical cable that is entirely composed of dielectric materials, contains necessary support systems, and can be directly suspended on power poles. It is used for the communication of overhead high-voltage transmission system, and can also be used as a communication line in lightning-prone areas and long-span overhead laying environments. [0003] Guangdong Province is located on the west coast of the Pacific Ocean, bordering the South China Sea, with a coastline of 3,368km and facing a vast tropical ocean. There are 3.3 tropical cyclones landed in Guangdong every year on average, with a maximum of 7; the average number of tropical cyclones that seriously affect Guangdong is more than 5 every year, ranking first in the country.

AI Technical Summary

Problems solved by technology

In the future, strong typhoons or even super typhoons that land on the ground will seriously affect the safe operation of power grid communication cables

[0005] At present, there is no evaluation method for the anti-typhoon ability of ADSS lines, and it is impossible to predict the risk caused by typhoon and the anti-typhoon ability.
