摘要
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,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连接盒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(DTS)的光纤连接。DTS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。
Power cable conductor operating temperature is cable line safe operation of important parameters.In the cable manufacturing,temperature fiber 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 evaluation 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 DTS（distributed light temperature measurement system） optical fiber connection.DTS through the preset in cable division within the conductor temperature optical fiber cable conductor temperature to realize on-line monitoring.
