Description

Technical Field

[0001] The invention relates to the technical field of hardware and electrical materials, in particular to an insulating self-adhesive tape with a temperature monitoring function. Background Art

[0002] Copper busbars are key conductive components on the low-voltage side of the main transformer in substations and need to be insulated to prevent short circuits or discharges. Existing materials rely on regular manual inspections or infrared temperature measurement, which have corresponding lags and cannot cover hidden areas.

[0003] Traditional self-adhesive insulation tape used to insulate the copper busbars on the low-voltage side of the substation's main transformer only provides a single insulation function. Thermochromic insulation tape, typically made of thermochromic material, indirectly reflects temperature changes through color changes, making it impossible to monitor the busbar's operating temperature in real time. Furthermore, the self-adhesive tape prevents accurate infrared temperature measurement. When the busbars overheat locally due to overload or poor contact, the temperature cannot be monitored, leading to aging and failure of the tape, which can even cause fires. Summary of the Invention

The self-adhesive insulating substrate layer 2 is used to stick the insulating self-adhesive tape with a temperature monitoring function on the copper busbar and has an insulating effect. The temperature sensing layer 3 of this embodiment has a distributed flexible temperature sensor array and a data transmission module connected to the distributed flexible temperature sensor array. The real-time temperature of the copper busbar is obtained through the distributed flexible temperature sensor array, and the real-time temperature data is output through the data transmission module. Therefore, the insulating self-adhesive tape with a temperature monitoring function of the present invention integrates a temperature real-time monitoring function combination while ensuring insulation performance, realizes dynamic perception and abnormal warning of the copper busbar temperature, and improves the safety of the equipment.

[0034] The self-adhesive insulating substrate layer 2 is tightly attached to the copper busbar, with a withstand voltage of ≥20kV and an operating temperature range of -40℃~150℃.

[0035] The insulating self-adhesive tape with a temperature monitoring function of the present invention is integrated: no additional sensor needs to be installed, the construction process is simplified, and the risk of insulation layer damage is reduced.

[0036] Real-time monitoring: Remote transmission of digital temperature data, supporting historical data tracing and intelligent analysis.

[0037] High reliability: The shielding layer design reduces electromagnetic interference, and the sensor life is synchronized with the insulation material.

[0038] In some embodiments, the outer protective film 1 has a plurality of spaced horizontal line marks 11 along the length direction, and the temperature sensing layer 3 located between two adjacent horizontal line marks 11 has a distributed flexible temperature sensor array and a data transmission module connected to the distributed flexible temperature sensor array.

[0041] In this embodiment, the distributed flexible temperature sensor array includes a flexible nano-silver wire conductive grid, which is embedded in the temperature sensing layer 3 or printed on the side of the temperature sensing layer 3 facing the self-adhesive insulating substrate layer 2. The resistance value changes linearly with temperature, realizing dynamic perception of the copper busbar temperature and abnormal warning, thereby improving the safety of the equipment.

[0042] In some embodiments, the distributed flexible temperature sensor array includes an FBG fiber sensor array or a thermistor, which is embedded in the temperature sensing layer 3. Fiber Bragg grating (FBG) sensors are used instead of silver nanowire grids to monitor temperature through changes in light wavelength.

[0043] In some embodiments, the temperature-monitoring insulating self-adhesive tape further includes a bottom release paper liner 4, which is disposed on the side of the self-adhesive insulating substrate layer 2 facing away from the outer protective film 1. After peeling off the bottom release paper liner 4, the temperature-monitoring insulating self-adhesive tape is directly wrapped around the copper busbar, with the temperature-sensing layer facing the copper busbar surface. The tape then adheres automatically after being pressed. The bottom release paper liner 4 facilitates storage and removal during installation.

Wireless data transmission and threshold alarms: Embedded modules offer low-power design.

[0048] In some embodiments, the data transmission module is a wired transmission module having an output line extending to the insulating self-adhesive tape with temperature monitoring function, and the output line is connected to the monitoring terminal to achieve real-time monitoring. The monitoring terminal supports threshold alarms (such as >80°C triggering an early warning). The exposed output line is connected to an external collector. The process is simple, but the protection is poor and it is susceptible to mechanical damage and oxidation.
