根据本发明实施例的配合环网柜堵头测温系统使用的测温堵头，通过设置在主嵌件安装槽110中的主嵌件200，可以实现对堵头本体100的安装，相较于传统的上嵌体加下嵌体的结构，极大的减少了金属嵌件，节约了成本。通过无源无线测温芯片300可以实现对环网柜的内部温度的检测；同时通过感应外部的电磁波信号方式可以直接获取电源进行工作，不需要再通过自取电或电场耦合取电等方式获取电源，极大的延长了使用的寿命；此外，因为不需要其他的辅助取电部件，也可以减小故障发生的概率，发生故障之后减小故障带来的损害。According to the temperature measuring plug used with the temperature measuring system of the ring main unit plug according to the embodiment of the present invention, the main insert 200 arranged in the main insert installation groove 110 can realize the installation of the plug body 100, compared with Compared with the traditional structure of the upper inlay and the lower inlay, the metal inserts are greatly reduced and the cost is saved. The internal temperature of the ring network cabinet can be detected through the passive wireless temperature measurement chip 300; at the same time, the power can be directly obtained to work by sensing the external electromagnetic wave signal, and there is no need to obtain electricity by self-electricity or electric field coupling.

In many cases, in order to ensure the accuracy of measurement or to ensure that one passive wireless temperature measurement chip 300 can continue to work after damage, multiple passive wireless temperature measurement chips 300 are arranged at the same time to avoid the above problems.
在本发明的一些实施例中，无源无线测温芯片300型号为TSC2020-3、TSC2509-3或TSC1309-3。这些型号仅作为本技术方案的具体实例，还可以是其他常规已知的无源无线测温芯片300型号In some embodiments of the present invention, the model of the passive wireless temperature measuring chip 300 is TSC2020-3, TSC2509-3 or TSC1309-3. These models are only specific examples of this technical solution, and can also be other conventionally known passive wireless temperature measurement chip 300 models
在本发明的一些实施例中，上述配合环网柜堵头测温系统使用的测温堵头还包括设置于堵头本体100内的电场屏蔽罩400，电场屏蔽罩400用于均匀堵头本体100内部电场。通过电场屏蔽罩400均匀堵头本体100内部电场，可以将减少堵头本体100结构中的局放，可以提高温度检测的准确性。In some embodiments of the present invention, the temperature measuring plug used in conjunction with the temperature measuring system for the plugging head of the ring main unit further includes an electric field shielding cover 400 disposed in the plug body 100 , and the electric field shielding cover 400 is used to uniformize the plug body 100 internal electric field. By using the electric field shield 400 to evenly distribute the electric field inside the plug body 100 , the partial discharge in the structure of the plug body 100 can be reduced, and the accuracy of temperature detection can be improved.
在本发明的一些实施例中，电场屏蔽罩400采用半导电材料。半导电材料具有较好的均匀电场的能力，也可以采用其他的材料。In some embodiments of the present invention, the electric field shield 400 uses a semiconducting material. Semiconducting materials have better ability to uniformize the electric field, and other materials can also be used.
在本发明的一些实施例中，电场屏蔽罩400的形状为半球形。采用半球形结构可以更好的均匀电场。采用其他的结构也可以均匀电场进而减小局放，但是却不如半球形的效果显著。参考图1，半球形的结构和上嵌件的表面将无源无线测温芯片300包围起来，以使得温度检测更加准确。In some embodiments of the present invention, the electric field shield 400 is hemispherical in shape. The use of a hemispherical structure can better uniform the electric field. Using other structures can also uniform the electric field and reduce partial discharge, but the effect is not as significant as the hemispherical effect. Referring to FIG. 1 , the passive wireless temperature measuring chip 300 is surrounded by the hemispherical structure and the surface of the upper insert, so as to make the temperature detection more accurate.
在本发明的一些实施例中，堵头本体100的材质采用环氧树脂。环氧树脂具备良好绝缘性能，可以对无源无线测温芯片300起到较好的保护作用。In some embodiments of the present invention, the material of the plug body 100 is epoxy resin. Epoxy resin has good insulating properties and can protect the passive wireless temperature measuring chip 300 well.
