Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, obtaining other drawings based on these drawings without creative effort still falls within the scope of the present invention.

[0019] Figure 1 This is a schematic diagram of a transformer temperature gauge device according to an embodiment of the present invention. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 The diagram shown is a schematic representation of an embodiment of a transformer temperature gauge device provided by the present invention. In this embodiment, it includes:

[0022] The sensing module detects the temperature signal of the target transformer and outputs it as a thermometer through multiple channels. The control module processes the received thermometer data using a preset program to determine the corresponding temperature and control signals. The feedback module drives a corresponding motor to deflect the pointer based on the received control signal, providing feedback on the corresponding temperature scale. The sensing module includes at least a temperature sensing unit for outputting four temperature signals and comparing channel signals. When a channel is detected as damaged, the temperature signal is switched to a normal channel. The sensor probe of the sensing module has two embedded dual-channel Pt100 chips, enabling four temperature signal outputs and channel signal comparison. In case of channel damage, it can switch to a normal signal output channel, achieving self-testing and self-healing of the thermometer.

[0023] In a specific embodiment, the control module is specifically used to determine the corresponding transformer oil temperature and winding temperature data based on the temperature gauge, forming a transformer temperature change database, and monitoring the transformer temperature change database according to a preset temperature change standard. If abnormal data is detected, a corresponding alarm signal is output. The module collects transformer oil temperature and winding temperature data, uploads it to the Dianhong IoT system terminal, forms a transformer temperature change database, and sends a signal upon detecting abnormal data. Test personnel can retrieve transformer operating data on-site or in the background to conduct tests.

[0024] The control module incorporates a Dianhong control chip, which includes at least a chip for the Dianhong OS system and a Bluetooth communication module. It uses a pre-defined unified protocol standard to call upon connected devices in real time. Specifically, the Dianhong control chip monitors connected devices in real time. If a device is detected as having been integrated with Dianhong, it flexibly networks and autonomously coordinates operations using the unified protocol standard. The Dianhong control chip selects chips and Bluetooth communication modules compatible with the Dianhong OS system to ensure the accuracy and efficiency of data output. The chip facilitates data processing and logic processing for temperature meters, internal communication, and power monitoring. The Dianhong devices undergo network access testing, with tests conducted in seven aspects across two dimensions: code open-source compliance and basic IoT characteristics. All tests were passed.

[0025] The sensing module also includes a resistive temperature sensing element for transmitting digital signals and splitting the signal during transmission. Employing digital signal transmission allows for intermediate disassembly, is not limited by energized distance, and enables live replacement, thus achieving live troubleshooting of the main transformer.

[0026] In a specific embodiment, the feedback module further includes a microswitch that can drive a microswitch to generate a corresponding execution signal based on the received control signal, and control the corresponding motor to perform a corresponding operation through the execution signal. The feedback module also includes a scale with multiple temperature graduations, located on one side of the pointer. Upon receiving a temperature-sensing electrical signal, the pointer deflects, shifting to indicate the corresponding temperature on the scale, and can also drive the microswitch to issue a corresponding control signal.

[0027] In summary, implementing the embodiments of the present invention has the following beneficial effects:

[0028] The transformer temperature gauge device provided by this invention improves the accuracy and reliability of transformer temperature monitoring, optimizes maintenance efficiency, supports intelligent decision-making, and promotes system integration through multi-channel data transmission, self-checking and self-healing of the temperature measuring device, and live fault repair capabilities. Data acquisition: Secondary voltage data of the CVT is collected through a dispatch automation system. Using the HarmonyOS system as a platform, and aiming for high reliability and uninterrupted fault repair, it employs multi-channel data transmission (reliability of N-3), self-checking and self-healing of the temperature measuring device (20 man-hours per unit per year), and live fault repair capabilities (averaging a reduction of transformer downtime by 18 hours), thus reducing direct economic losses.
