Description

一种自承载抗拉型风能电力电缆
技术领域
本发明涉及电力电缆技术领域,具体为一种自承载抗拉型风能电力电缆。
背景技术
国家电线电缆质量监督检验中心在2009年5月份正式实施了低温风能电力电缆的技术规范,该规范在结构尺寸、使用的材料及性能、电压等级、使用环境温度、使用场合、试验方法上进行了详细描述。在这之前低温风能电力电缆在产品质量上良莠不齐,大量的不合格或恶劣产品充斥市场,给用户带来经济损失,严重威胁电气控制设备、电力系统的正常运行。由于国家对可再生能源的需求不断增加。低温风能电力电缆的导体采用多股分层的绞合方式,绞合导体的节距范围:股线21-25倍、内层:17-20倍、外层:11-14倍,成缆按不同的代号取不同的成缆节径比,移动场合:节径比不大于成缆外径的14倍;非移动场合:节径比不大于成缆外径的18倍。然而在风能电力电缆方面电缆的使用中有很多的缺陷例如:
1、现有技术中风能电力电缆运用的电缆油气其实借助风能发电,使得在风力发电设备上长期往复的正反扭曲,绞合的导体和导电线芯寿命不是很长,电缆容易变形,导致易被扭断。而这些缺陷的原因,是因为绞合的导体节距稀疏、绞合导体不是很紧密,没有正反退扭时的预扭力则容易损坏,故而无法满足现有技术所需。
2、现有技术中风能电缆在外界长时间使用时由于其内部一般采用条状填充棉而且由于其缆芯内部空气量还是较多,在电力传输中产生的热量影响下很可能造成缆芯外侧保护被氧化而在扭矩力作用下,保护层会粉碎造成漏电使得电能的浪费,故而无法满足现有技术所需。
发明内容
本发明的目的在于提供一种自承载抗拉型风能电力电缆,以解决上述背景技术中提出的问题。
为实现上述目的,本发明提供如下技术方案:一种自承载抗拉型风能电力电缆,包括导体、承载芯、隔离层、防护铜丝和保护套,所述保护套内侧黏贴有第二橡胶层和第一橡胶层,所述第二橡胶层和第一橡胶层之间由八根防护铜丝和填充物绞合而成,所述第一橡胶层内侧设置有四根缆芯,所述缆芯之间的空隙的轴心位置黏贴有一根抗拉铜芯,所述缆芯由内而外分别由承载芯、导体和隔离层构成。
优选的,所述缆芯内部的导体和隔离层之间设置有绝缘层。
优选的,所述第一橡胶层内侧缆芯和抗拉铜芯之外的空隙由填充物均匀填充。
优选的,所述保护套外围涂抹有油脂层。
优选的,所述抗拉铜芯长度皆超过保护套三十厘米。
与现有技术相比,本发明的有益效果如下:
1、本发明通过在保护套内侧黏贴有第二橡胶层和第一橡胶层,使得其在使用时扭矩力产生后橡胶层具有一定柔软性,使得电缆产生预扭力,而且其内部有防护铜丝和填充物绞合而成,使得其防护铜丝和填充物也具有预扭力,并且由于橡胶具有很好的柔软性使得被第一橡胶层包裹的缆芯和被第二橡胶层包裹的防护铜丝皆节距紧密,故而也避免在长时间使用时电缆容易变形,导致易被扭断的可能。
2、本发明通过在第二橡胶层内部的缆芯和抗拉铜芯之间的空隙被填充物均匀填充使得其内部氧气含量大大降低,而且在缆芯外侧设置隔离层内层设置绝缘层,避免导体漏电造成电力的浪费损耗,而且在导体内部中心位置的承载芯和在四根缆芯中心的抗拉铜芯,使得电缆本身的抗力能力大大增加。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
请参阅图1-2,本发明提供一种技术方案:一种自承载抗拉型风能电力电缆,包括导体1、承载芯2、隔离层4、防护铜丝6和保护套8,所述保护套8内侧黏贴有第二橡胶层9和第一橡胶层7,所述第二橡胶层9和第一橡胶层7之间由八根防护铜丝6和填充物5绞合而成,所述第一橡胶层7内侧设置有四根缆芯12,所述缆芯12之间的空隙的轴心位置黏贴有一根抗拉铜芯10,所述缆芯12由内而外分别由承载芯2、导体1和隔离层4构成。
所述缆芯12内部侧导体1和隔离层4之间设置有绝缘层3,避免隔离层4被氧化后出现漏电的可能,所述第一橡胶层7内侧缆芯12和抗拉铜芯10之外的空隙由填充物5均匀填充,使得内部空气更少,避免缆芯12长时间使用被氧化的速度,所述保护套8外围涂抹有油脂层11,涂抹油脂层11使得其保护套抗氧化能力更强电缆使用寿命大大增加,所述抗拉铜芯10长度皆超过保护套8三十厘米,安装好后起到保护作用避免拉力过大而将电缆拉断。
工作原理:使用时将电缆安装在风能发电所需处,并且将抗拉铜芯10多出来的一段固定在牢固处起到抗拉作用,在安装时导体1内部的承载芯2也随着导体1被牢固的安装在设备上,使得其抗拉能力大大增加,当产生扭矩力时第二橡胶层9和第一橡胶层7有一定柔软性,使得电缆产生预扭力,而且其内部有防护铜丝6和填充物5绞合而成,使得其防护铜丝6和填充物5也具有预扭力,并且由于橡胶具有很好的柔软性,使得被第一橡胶层7包裹的缆芯12和被第二橡胶层9包裹的防护铜丝6节距紧密,故而避免在长时间使用时电缆容易变形,导致易被扭断的可能。
尽管已经示出和描述了本发明的实施例,对于本领域的普通技术人员而言,可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型,本发明的范围由所附权利要求及其等同物限定。
