Description
技术领域 technical field
本申请涉及一种大电流硬性电缆。This application relates to a high current rigid cable.
背景技术 Background technique
目前，国内母线在技术上和结构上越来越难满足母线发热和短路电动力的要求，由此引起附加损耗、集肤效应系数的增大，造成载流能力的下降、电流分布不均匀。尤其是大电流的出线，不仅有母线桥本身的电动力问题、发热问题，还有母线桥支柱绝缘子、钢构架以及母线桥附近混凝土柱、基础内的钢筋在电磁场中感应涡流引起的发热问题。传统电缆截面小，其载流量小，不适合用于大电流输配电。At present, it is becoming more and more difficult for domestic busbars to meet the requirements of busbar heating and short-circuit electromotive force technically and structurally, which will cause additional loss, increase of skin effect coefficient, decrease of current carrying capacity and uneven current distribution. Especially for the outgoing line of large current, there are not only the electrodynamic problems and heating problems of the bus bridge itself, but also the heating problems caused by the eddy current induced in the electromagnetic field by the insulators of the bus bridge pillars, the steel frame, the concrete columns near the bus bridge, and the steel bars in the foundation. Traditional cables have a small cross-section and a small carrying capacity, making them unsuitable for high-current power transmission and distribution.

本申请提供一种管型电缆，其电缆芯为管型导体，管型导体外层依此有内屏蔽层、绝缘层、外屏蔽层、金属屏蔽层、护套层，在金属屏蔽层上加装接地引线。The application provides a tubular cable, the cable core is a tubular conductor, and the outer layer of the tubular conductor has an inner shielding layer, an insulating layer, an outer shielding layer, a metal shielding layer, and a sheath layer. Install the ground lead.
优选地，管形导体采用铜管、铝管或合金管。Preferably, the tubular conductor is a copper tube, an aluminum tube or an alloy tube.
优选地，内屏蔽层与外屏蔽层采用半导电材料。Preferably, the inner shielding layer and the outer shielding layer are made of semi-conductive materials.
优选地，绝缘层采用氯磺化聚乙烯橡胶和聚四氟乙烯材料。Preferably, the insulating layer is made of chlorosulfonated polyethylene rubber and polytetrafluoroethylene.
优选地，护套层分为内护套层和外护套层。Preferably, the sheath layer is divided into an inner sheath layer and an outer sheath layer.
本实用新型由于采用铜管、铝管或合金管作为电缆芯，扩大了电缆的截面积，使其载流量增大，交、直流电阻比值变大，解决了高低电压等级(0.4kV～110kV)大电流导线与绝缘体设备的接口以及大电流输配电安全可靠性更高的问题，适应各种供电领域和污秽等级高的恶劣复杂环境的使用。Because the utility model adopts copper tube, aluminum tube or alloy tube as the cable core, the cross-sectional area of the cable is enlarged, the carrying capacity is increased, the ratio of AC and DC resistance is increased, and the high and low voltage levels (0.4kV～110kV) are solved. The interface between high-current wires and insulator equipment and the higher safety and reliability of high-current transmission and distribution are suitable for use in various power supply fields and harsh and complex environments with high pollution levels.
