Description

一种电缆接头均压罩 技术领域
本发明涉及电力设备技术领域，特别涉及一种电缆接头均压罩。
背景技术
随着电力行业投入的进一步加大，在冶炼、煤等大中型企业中，电力电缆得以广泛应用，其中电力安全配送至关重要。随着电力负荷的不断增加，输电电缆接头温升问题，易对生产带来安全隐患，成为电力安全配送过程中主要的监测点。一旦电缆接头过热造成短路，容易导致大面积电缆烧坏，使设备停机，造成重大经济损失，故实时监测电力电缆的接头温度来辅助判断电缆线路的运行情况变得尤为重要。
现有的电缆接头温度检测方式多为检测电缆接头外部温度，因电缆接头内部有铜壳，屏蔽层，绝缘层等多种结构组成，当电缆接头线芯发热时，引起的外部温度变化并不大；同时当环境温度变化时，也会引起测量温度的变化，影响检测的准确性。
而市场上一些检测电缆接头内部温度的装置，需要在内部搭接电源同时将采集信号通过有线的方式传输出来，不仅安装复杂，而且后期维护成本也比较高。
发明内容
本发明旨在至少解决现有技术中存在的技术问题之一。为此，本发明提出一种电缆接头均压罩，内置无源无线测温芯片可提高温度检测的准确性。

无源无线测温芯片，用于检测电缆接头内部温度并向外部接收天线反馈温度信号；
芯片固定机构，用于将所述无源无线测温芯片固定于所述凹槽内。
根据本发明第一实施例的电缆接头均压罩，至少具有如下有益效果：通过 在均压罩外侧开槽，并在凹槽内置无源无线测温芯片，直接从电缆接头内部实现精准测温，避免外界温度变化的干扰，同时测温芯片无需电源供电和有线传输模块，安装使用便捷，且有效降低成本。
根据本发明的一些实施例，所述无源无线测温芯片具有一个或多个。
根据本发明的一些实施例，所述无源无线测温芯片型号为TSC2020-3。
根据本发明的一些实施例，所述无源无线测温芯片型号为TSC2509-3。
