[0054] Transformers used for differential communication offer excellent anti-interference capabilities, which is beneficial for:

[0055] Improved communication stability: Traditional communication methods may be affected by interference from power lines and other devices, leading to degraded communication quality or even complete communication failure. Differential transformers, however, can effectively resist these interferences, improving communication stability and ensuring reliable and continuous communication.

[0056] Reducing the bit error rate: In traditional communication methods, interference can lead to data transmission errors, resulting in a higher bit error rate. Differential transformers can suppress interference signals, reduce data transmission errors, lower the bit error rate, and improve the accuracy and reliability of data transmission.

[0057] Enhancing system security: Differential transformers can effectively resist external interference signals and electrical noise, thereby improving system security and stability. This is especially important for areas where data security is crucial.

[0058] Improving system reliability and interference immunity: Differential transformers can effectively suppress interference signals from power lines and other devices, thus improving system reliability and interference immunity. This is particularly suitable for applications that need to operate in harsh environments.

[0059] By combining the layout of this solution with standard data, a stable data verification scheme and interference source assessment are achieved, which facilitates guidance during maintenance.

[0060] Reduced system cost: Differential transformers can effectively reduce system cost because they can resist interference signals, reduce system maintenance and repair costs, and lower the overall system cost.

[0061] A digital transformer includes a magnetic shielding shell 1. A transformer body 3 is mounted on the inner wall of the magnetic shielding shell 1 via an isolation frame 2. A controller 5 and a human-machine interface port 6 are mounted on the surface of the transformer body 3. The controller 5 is electrically connected to the transformer body 3 via a differential line 4. A power connection lug 7 electrically connected to the transformer body 3 is provided on one side of the human-machine interface port 6. The magnetic shielding shell 1 provides external protection for the magnetic shielding module.

[0062] The surface of the magnetic shielding shell 1 is provided with a heat sink 10, and a display 9 is mounted on the surface of the heat sink 10. A mounting bracket 8 is fixedly connected to the lower surface of the magnetic shielding shell 1. Several overhead insulators 11 for cable support are fixed on the upper surface of the magnetic shielding shell 1. Several wiring lugs 12 are provided on the upper surface of the magnetic shielding shell.

[0063] The working principle of this invention is as follows:

[0064] During operation, the transformer's operating data and related monitoring data are transcoded by the data transcoding transmitter and transmitted via a differential circuit. Simultaneously, the data transcoding transmitter continuously transmits a standard signal via a single wire. The data undergoes anti-interference protective transmission through a magnetic shielding module and an isolator module, and is received by the data decoding receiver. The detected data is then transmitted to the multi-line differential communication module, and the standard signal is sent to the standard signal transmission module. At this point, the data integrity verification module compares the detection data transmitted from multiple differential circuits, checking the integrity of the data transmitted from each circuit. Because the unified detection data transmission from multiple differential circuits is not simultaneous but occurs with a delay of several seconds, any data loss due to interference can be directly identified through comparison. The completed data, after comparison, is filtered by the filter module to remove any interference-affected data. After obtaining complete transmission data, and with the standard signal undergoing integrity verification by the data verification module, changes in affected and missing data over different time periods are sent to the control module. This allows the system to determine whether the received data changes during that time period are consistent with the standard signal data. If they are consistent, the transmission passes; otherwise, the data is fed back to the transcoding transmitter for retransmission. Under the influence of the interference feature analysis module, the time, frequency, intensity, or direction of interference is analyzed (multiple differential circuits are routed separately, and the distance from the interference source varies, resulting in different interference intensities, thus revealing the approximate direction of the interference source). Based on the analysis of the interference source characteristic data, the system assesses the interference intensity to determine whether it affects normal operation and whether the risk exceeds the preset limit. Specific data and assessments can be viewed through the display module. A comprehensive assessment can be conducted via the APP port in conjunction with environmental changes, and the transformer's location information can be obtained through the positioning module.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
