Wireless passive ring main unit temperature measuring device

In order to overcome the defects and existing problems in the prior art, the utility model provides a wireless passive ring main unit temperature measuring device which improves the sensing precision of an RFID temperature sensor and improves the communication distance of the RFID temperature sensor. And the RFID temperature sensor is very convenient to install and maintain. In order to achieve the purpose, according to the wireless passive ring main unit temperature measuring device, the top end of the copper nose is fixedly provided with the RFID temperature sensor, and the RFID temperature sensor is bent into an arc shape and then clings to the upper surface of the copper nose, so that the contact area between the RFID temperature sensor and the copper nose is increased, and the temperature can be obtained more accurately. And the RFID temperature sensor can be directly seen only by opening the insulating sleeve, so that the installation and the maintenance are very convenient. 为克服现有技术的不足及存在的问题，本实用新型创造提供一种
