[0023] Figure 1 This is a schematic diagram of a busbar passive wireless temperature measurement device, showing the overall layout of the RFID passive wireless temperature measurement sensor fixed to the busbar cable connection through the busbar cable fixing screws, as well as the signal transmission relationship between the RFID transceiver antenna and the sensor. Figure 2 yes Figure 1The partially enlarged exploded diagram in the figure intuitively shows the structural relationship and sequence of the various components of the device during installation, providing clear guidance for installation operations. Figure 3 This is a decomposition diagram of the RFID passive wireless temperature sensor, which provides an in-depth introduction to the internal structure of the sensor and the composition of its components, helping to understand the working principle and performance characteristics of the sensor.

[0024] It includes an RFID passive wireless temperature measurement sensor 1, an RFID transceiver antenna 2, and a bus cable fixing screw 3; the RFID passive wireless temperature measurement sensor 1 includes a silver-plated copper base plate 12, a thermal conductive sheet 13, a passive wireless temperature measurement module 14, and a flame retardant shell 15. The passive wireless temperature measurement module 14 is embedded in the flame retardant shell 15, and the thermal conductive sheet 13 is attached to the surface of the passive wireless temperature measurement module 14. The silver-plated copper base plate 12 covers and connects to the flame retardant shell 15 and is attached to the thermal conductive sheet 13; the silver-plated copper base plate 12 is provided with a mounting groove 121, and the bus cable fixing screw 3 is used to fasten the silver-plated copper base plate 12 to the bus cable 4 and the main bus bar 5.

[0025] This RFID passive wireless temperature sensor is fixed to the busbar cable connection using busbar cable fixing screws. This location accurately senses temperature changes at the busbar connection. The RFID transceiver antenna is used to wirelessly communicate with the sensor, sending request signals to the sensor and receiving signals back from the sensor.

[0026] The silver-plated copper bottom plate 12 is provided with threaded holes, and is fixedly connected to the flame-retardant housing 15 by fastening bolts 11 .

[0027] The silver-plated copper bottom plate 12 , the busbar cable 4 , and the main busbar bar 5 are sequentially connected, and both the busbar cable 4 and the main busbar bar 5 are provided with fixing holes for inserting the busbar cable fixing screws 3 .

[0028] This new RFID passive wireless temperature sensor consists of a silver-plated copper baseplate, a thermal pad, a passive wireless temperature measurement module, and a flame-retardant housing. The silver-plated copper baseplate offers excellent thermal conductivity, quickly transferring heat from the busbar connection to the thermal pad. The thermal pad further transfers heat to the passive wireless temperature measurement module, enabling it to accurately sense temperature changes. The flame-retardant housing protects the internal components and is flame-retardant, enhancing the device's safety in power environments.

[0029] It also includes a front gasket 61, which is placed between the bus cable fixing screw 3 and the silver-plated copper base plate 12; it also includes a rear gasket 62, a spring piece 7, and a nut 8. The rear gasket 62 and the spring piece 7 are sequentially sleeved on the bus cable fixing screw 3, and the rear gasket 62 is attached to the main busbar 5 and fastened with the nut 8.

[0030] When the RFID transceiver antenna sends a request signal to the RFID passive wireless temperature sensor, the sensor converts the received wireless signal into electrical energy and begins operation. The passive wireless temperature measurement module in the sensor senses the temperature change and wirelessly transmits the temperature data back to the antenna. After receiving the signal, the antenna transmits the temperature data to relevant monitoring systems or equipment, allowing personnel to obtain real-time temperature information at the busbar connection.

[0031] During installation, first place the gasket and spring washer on the bolts in sequence, then pass the bolts through the busbar cable, main busbar, and RFID passive wireless temperature sensor (through their corresponding mounting holes), and finally tighten them with the fixing screws. Ensure that all components are installed accurately and securely to ensure the normal operation of the device and the accuracy of temperature measurement.

[0032] When installing the sensor, please note: At the busbar cable connection, follow Figure 2 Follow the exploded view of the installation instructions shown. Secure the RFID passive wireless temperature sensor in place using the busbar cable fixing screws. Ensure the sensor's silver-plated copper baseplate is in close contact with the busbar connection to ensure good heat conduction. During installation, carefully check the installation sequence and tightness of the gaskets, spring washers, and bolts to prevent loosening or poor contact of the sensor due to improper installation, which could affect temperature measurement accuracy and device stability.

[0033] Antenna placement considerations: Install the RFID transceiver antenna at an appropriate distance from the sensor to ensure stable transmission of request signals to the sensor and accurate reception of return signals. The antenna's placement should consider signal transmission stability and reliability, avoiding interference from other sources of electromagnetic interference. Furthermore, the antenna's direction and angle should be appropriately adjusted based on the actual application scenario and monitoring requirements to optimize signal transmission.

[0034] System debugging:

[0035] After the device is installed, the system is debugged. First, a test signal is sent to the RFID transceiver antenna through the relevant equipment to check whether the sensor can normally receive the signal and convert it into electrical energy for operation.

[0036] Then, observe whether the temperature data sent back by the sensor is accurate and stable. You can calibrate and verify the temperature measurement accuracy of the sensor by comparing it with a standard thermometer.

[0037] If abnormal temperature data or unstable signal transmission is found, you should promptly check whether the device is installed correctly, whether each component is working properly, whether there are any interference sources, and make corresponding adjustments and troubleshooting.

[0038] Daily maintenance:

[0039] Regularly inspect and maintain the busbar passive wireless temperature measurement device, mainly including checking the fixation of the sensor, the connection status of the antenna and the overall operating status of the device.

[0040] Clean the dust and debris on the sensor surface to ensure that its thermal conductivity is not affected. Also, check whether the antenna is damaged or deformed, and replace it if necessary.

[0041] The device is calibrated and tested regularly to ensure that its temperature measurement accuracy and performance always meet the requirements of power system monitoring.

[0042] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
