Description
技术领域 technical field
本发明专利涉及一种光缆的接头结构及连接方法，用于连接多相电光纤复合电力电缆，应用于智能电网建设中的多相电光纤复合电力电缆的施工、维护和抢修。The patent of the present invention relates to a joint structure and connection method of an optical cable, which is used to connect multi-phase electric fiber composite power cables, and is applied to the construction, maintenance and emergency repair of multi-phase electric fiber composite power cables in the construction of smart grids.
背景技术 Background technique
建设中的智能电网首要作用是有效保证电力安全可靠性，使较传统电网更加坚强，可以有效地抵御自然灾害、外力破坏等各类突发事件给电力系统造成的影响；并具有强大的“自愈”功能，可以通过远程设备在线监视和系统信息分析，更加及时、准确地预测和处置各类系统故障。这就需要一种能够在高电压、强电场环境，既能在线探测电力电缆运行状态，又能高速大容量传输探测信息的技术手段。The primary function of the smart grid under construction is to effectively ensure the safety and reliability of power, making it stronger than the traditional grid, and can effectively resist the impact of natural disasters, external damage and other emergencies on the power system; and has a strong "autonomous power grid". "Recovery" function can predict and deal with various system failures in a more timely and accurate manner through online monitoring of remote equipment and system information analysis. This requires a technical means that can not only detect the running status of power cables online, but also transmit detection information at high speed and large capacity in a high-voltage, strong electric field environment.
光纤具有径细、质软、重量轻的机械性能。具有绝缘、无电磁辐射的电气性能。还具有耐水、耐高温、耐腐蚀的化学性能。光纤传送的光信号具有抗电磁干扰和原子辐射的性能。用光纤制作传感器能够在对人有害的地区(如核辐射区和强电磁场合)，接收人的感官所感受不到的外界信息。同时，光纤也能实现远距离、高速大容量的信息通信。Optical fiber has the mechanical properties of thin diameter, soft quality and light weight. It has the electrical properties of insulation and no electromagnetic radiation. It also has the chemical properties of water resistance, high temperature resistance and corrosion resistance. Optical signals transmitted by optical fibers are resistant to electromagnetic interference and atomic radiation. Sensors made of optical fibers can receive external information that cannot be sensed by human senses in areas that are harmful to humans (such as nuclear radiation areas and strong electromagnetic fields). At the same time, optical fiber can also realize long-distance, high-speed and large-capacity information communication.
因此应运而生的光纤复合电力电缆能较好地满足了智能电网建设的需要。但在光纤复合电力电缆应用中，就要面临解决在多相电光纤复合电力电缆应用中的光缆中间接头问题。在常规的通信光缆中间接头方法中，需要连接的2条光缆都要各留有一段余长用于光纤的接续。由于将径细、质软、易折的多芯束光纤缆嵌入到粗硬的电力电缆中后，若按常规光缆连接方法连接2段复合电缆，就要从各复合电缆中剥出一定长度的光缆接续余长段。为此要分别截去2条需要连接的复合电力电缆端部相对应光缆余长度的多根电缆单相芯线。这样不但造成铜导体等贵重材料的浪费，而且在抢修复合电缆接头中，毁坏的复合电缆也无法提供满足光缆接续所需要的电缆余长。Therefore, the optical fiber composite power cable that emerged at the historic moment can better meet the needs of smart grid construction. However, in the application of optical fiber composite power cables, it is necessary to solve the problem of the intermediate joint of optical cables in the application of multi-phase electric optical fiber composite power cables. In the conventional communication optical cable intermediate splicing method, the two optical cables to be connected each have a surplus length for optical fiber splicing. After embedding the thin, soft and easy-to-break multi-core bundle optical fiber cable into the thick and hard power cable, if two sections of composite cables are connected according to the conventional optical cable connection method, a certain length of fiber optic cable must be stripped from each composite cable. The optical cable is connected to the remaining length. For this reason, the multi-cable single-phase core wires corresponding to the remaining length of the optical cable at the ends of the composite power cables that need to be connected should be cut off respectively. This not only causes the waste of valuable materials such as copper conductors, but also the damaged composite cable cannot provide the cable surplus length required for optical cable connection in the emergency repair and repair of cable joints.
鉴于此，有必要提出一种新的结构及方法用于改善上述问题。In view of this, it is necessary to propose a new structure and method for improving the above problems.
