Abstract
The optical fiber composite overhead line (OPPC) combines electricity transmission and information transmission, is used increasingly widely in the electric power system, further broadening the application area of our country’s special cable in the meantime. In heavy ice-phased regions, the designing parameters and technical requirements should be of higher standards, or it will directly affect the safety and stability of electric communication system’s operation. Therefore, OPPC under ice condition performance changes should cause enough attention. This article proposes simulation test of OPPC under ice-cladding condition, basing on which the mechanical properties and light transmission performance were calculated and analyzed. Then it comes to a conclusion that the ice-cladding has a variety of impact on OPPC in the stress and strain of fiber optic cable, optical transmission performance, residual RTS and other related elements. The test results show that the corresponding tension values under ice thickness would change and should be taken seriously into consideration when discussing the application of OPPC line under ice-phased condition.
Highlights
OPPC is developed in recent years gradually a kind of new type of electric power special fiber optic cable, and power transmission and double function of communication
Transmission line conductor ice coating side of the issue has caused the attention and research, but OPPC and conductor is different, which is formed in the element of optical fiber composite phase line of a new type of electric power special optical cable, mainly consisting of optical unit and wire unit
Test attenuation curve is shown in figure I, you can see, in the process of ice for a long time, the cable tension, make its produce strain, causes the fiber in the OPPC released in full, fiber began to stress, the additional damping increase
Summary
OPPC is developed in recent years gradually a kind of new type of electric power special fiber optic cable, and power transmission and double function of communication. It has been widely used in related to OPGW. Compared with special ADSS optical cable, OPPC has many unique advantages, which make it in our country granted a broad application prospect in low voltage power distribution network. Used special OPPC new technology has solved the power cable in electric corrosion, the disadvantages of theft, struck by lightning, provide low voltage intelligent power grid automation development in the future with optical fiber communication channel. A practical engineering application of OPPC ice simulation experiment was carried out, based on the certain condition of ice thickness OPPC performance of theoretical calculation and experimental study, analysis the influence of ice coating on properties of OPPC
