分割导体内预置测温光纤的XLPE电缆及附件的研制及试验

电力电缆导体运行温度是电缆线路安全运行的重要参数。在电缆制造时，将测温光纤预置于电缆分割导体内。并对其配套的电缆附件进行了初期的电气性能、光纤连接、引出的可操作性进行模拟试验。在预鉴定试验线路安装时，两段电缆导体内的光纤在接头的导体连接管外进行连接。在电缆线路两端户外终端（或GIS终端）处，将电缆分割导体内的预置光纤引出到终端外部与分布式光纤测温系统的光纤连接。分布式光纤测温系统通过预置于电缆分割导体内的测温光纤实现对电缆导体温度的在线监测。

Split conductor in preset temperature fiber XLPE cables and accessories of the development and test

able conductor operating temperature is cable line safe operation of important parameters. In the cable manufacturing, temperature fiber is preset in cable division within the conductor. And its supporting the cable accessories at the early stage of the electrical properties, optical fiber connection, elicit the maneuverability of the simulated test. In the preliminary pre-qualification test line installation, two paragraphs in the optical fiber cable conductor connection box in the conductor connecting pipe from the outside of the connection. In the cable line ends outdoor terminal (or GIS terminal) place, will split conductor cable within the preset fiber derivation to terminal external and distributed light temperature measurement system) optical fiber connection. through the preset in cable division within the conductor temperature optical fiber cable conductor temperature to realize on-line monitoring.
