Description

一种耐高温电磁线
技术领域
本发明涉及一种耐高温电磁线，具体涉及一种耐高温潜水电动机定子绕组电磁线。
背景技术
现有的潜水电动机定子绕组电磁线最里层是铜芯1，中间层是聚乙烯层，外层是尼龙层3，由于地热井中的使用环境极为恶劣，井水温度最高可达100℃左右，加上潜水电动机本身的温升，普通的电磁线根本无法承受这样的温度及环境，经常会发生绝缘层烧结变形、绝缘值急剧下降、局部发生电击穿等现象，严重的影响了电机在热水井中的正常运行使用，导致电机故障频繁发生。
发明内容
本发明的目的就是为了克服现有技术的不足，而提供一种耐高温电磁线。
为了实现上述目的本发明采用的技术方案是：
一种耐高温电磁线，包括交联聚乙烯绝缘层，聚四氟乙烯护套层和铜芯，其特征在于：所述的耐高温电磁线铜芯外包裹有交联聚乙烯绝缘层；交联聚乙烯绝缘层外包裹有聚四氟乙烯护套层。
与现有技术相比本发明的有益效果是：绝缘层强度好，耐温高，绝缘能长期保持较高的数值，无局部击穿现象，使用寿命长，性能稳定性极强，电磁线工作温度能适用于最高150℃，电机可长期工作于介质温度95℃以下的热水井中，提高电机运行周期，减少起吊和维修成本。
附图说明
下面结合附图对本发明作进一步说明。
图1现有电磁线的剖面示意图；
图2是本发明实施例的剖面结构示意图；
图符说明：1. 铜芯；2.聚乙烯层；3.尼龙层；4.交联聚乙烯绝缘层；5.聚四氟乙烯护套层。
具体实施方式
图1现有电磁线的剖面示意图；现有的潜水电动机定子绕组电磁线最里层是铜芯1，中间层是聚乙烯层，外层是尼龙层3，现有的电磁线无法承受地热井中的高温环境，经常会发生绝缘层烧结变形、绝缘值急剧下降、局部发生电击穿等现象，严重的影响了电机在热水井中的正常运行使用，导致电机故障频繁发生。
实施例
图2是本发明实施例的剖面结构示意图；本发明一种耐高温电磁线，包括交联聚乙烯绝缘层4，聚四氟乙烯护套层5和铜芯1，其特征在于：所述的耐高温电磁线铜芯1外包裹有交联聚乙烯绝缘层4；交联聚乙烯绝缘层4外包裹有聚四氟乙烯护套层5。这样绝缘层强度好，耐温高，绝缘能长期保持较高的数值，无局部击穿现象，使用寿命长，性能稳定性极强，可以提高电机运行周期，减少起吊和维修成本。
