Description

一种新型防雷抗压电缆
技术领域
本发明涉及电气设备领域，尤其涉及一种新型防雷抗压电缆。
背景技术
电气设备包括一次设备和二次设备，电缆属于电气设备中的二次设备。随着我国经济的不断发展，电缆的应用范围越来越广，其性能要求也越来越高。传统的电缆耐热性能差，在受到雷击时，其内的缆芯容易被烧断，严重影响电缆的推广与使用。
发明内容
基于背景技术存在的技术问题，本发明提出了一种新型防雷抗压电缆，以解决上述技术问题。
本发明提出的一种新型防雷抗压电缆，包括：缆芯、屏蔽层、接地层、隔热层和外护套；缆芯包括多根线芯、芯体和绕包层，多根线芯绕所述缆芯中心呈环状分布，线芯包括位于中部的导体、依次包覆在导体外部的绝缘层和耐热层，芯体位于任意相邻两个线芯之间，并与之相抵，其采用弹性吸热材料制成，且与线芯配合使所述缆芯具有圆形截面，绕包层采用隔热材料绕包在所述线芯和芯体外周，屏蔽层包覆在所述缆芯外部，接地层包覆在屏蔽层外部，隔热层包覆在接地层外部，外护套包覆在隔热层外部。
本发明提出的一种新型防雷抗压电缆，在受到雷击时，接地层短时发热量小，降低了缆芯因雷击被烧断的几率，并起到部分屏蔽电磁波的功能；在雷击情况下，隔热层能够将大部分热量隔离在缆芯之外，缆芯内部的线芯仍能正常工作；线芯之间的芯体能够吸收进入缆芯的热量，使线芯温度不会上升过高，保证了线芯的使用性能，在受到外力时，芯体也可通过自身的弹性性能抵消部分应力，使线芯不会因撕扯而发生短断芯；耐热层在提升线芯耐热性能的同时，也将线芯隔离，即使绝缘层融化，相邻线芯内的导体也不会发生接触，保证了电力传输的稳定。本发明提出的新型防雷抗压电缆，耐热性能佳，电力传输稳定，在雷击情况下仍可正常工作。
附图说明
图1为本发明提出的一种新型防雷抗压电缆的结构示意图。
具体实施方式
如图1所示，图1为本发明提出的一种新型防雷抗压电缆的结构示意图。
参照图1，本发明提出的一种新型防雷抗压电缆，包括：缆芯、屏蔽层4、接地层5、隔热层6和外护套7；缆芯包括多根线芯1、芯体2和绕包层3，多根线芯1绕所述缆芯中心呈环状分布，线芯1包括位于中部的导体11、依次包覆在导体11外部的绝缘层12和耐热层13，芯体2位于任意相邻两个线芯1之间，并与之相抵，其采用弹性吸热材料制成，且与线芯1配合使所述缆芯具有圆形截面，绕包层3采用隔热材料绕包在所述线芯1和芯体2外周，屏蔽层4包覆在所述缆芯外部，接地层5包覆在屏蔽层7外部，隔热层6包覆在接地层5外部，外护套7包覆在隔热层6外部。
本实施例中的电缆在受到雷击时，接地层5短时发热量小，降低了缆芯因雷击被烧断的几率，并起到部分屏蔽电磁波的功能；在雷击情况下，隔热层6能够将大部分热量隔离在缆芯之外，缆芯内部的线芯1仍能正常工作；线芯1之间的芯体2能够吸收进入缆芯的热量，使线芯1温度不会上升过高，保证了线芯1的使用性能，在受到外力时，芯体2也可通过自身的弹性性能抵消部分应力，使线芯1不会因撕扯而发生断芯；耐热层13在提升线芯1耐热性能的同时，也将线芯1隔离，即使绝缘层12融化，相邻线芯1内的导体11也不会发生接触，保证了电力传输的稳定。
耐热层13采用钢丝和铜丝混合编织而成，还起到了抗压、屏蔽功能。屏蔽层4采用镀锌铜丝编织而成，屏蔽层4不易氧化，并具备一定的机械性能。上述方案中的接地层5采用多根绞合的铜丝绕包而成，隔热层6采用玻璃纤维带绕包而成。
此外，外护套7采用弹性阻燃材料制成，使电缆耐磨抗压，在遇到明火的情况下，也不易被点燃。外护套7上设有多个散热孔71，通过散热孔71可将电缆内部的热量导出，有助于提升电缆的耐热性能。
本发明提出的新型防雷抗压电缆，耐热性能佳，电力传输稳定，在雷击情况下仍可正常工作。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
