Description

technical field [0001] The invention relates to a wireless real-time monitoring system for nitrogen pressure of a large transformer in transit, belonging to the technical field of large transformer transportation monitoring. Background technique [0002] With the acceleration of smart grid construction, the demand for large-scale transformers is gradually increasing in various places. If the large-scale transformers of 110KV and above are transported with oil, the weight will increase, which will easily cause equipment damage or potential safety hazards. Nitrogen is filled in the tank so that the body does not come into contact with the air and avoid damp and rust; since the air pressure in the transformer oil tank is required to be kept at 0.01-0.03MPa to prevent mechanical deformation caused by external air leakage and overpressure, it needs to be transported in nitrogen. The pressure is monitored during the process; the traditional nitrogen air pressure monitoring device ...

AI Technical Summary

Problems solved by technology

[0003] In order to ensure that the nitrogen pressure in the transformer maintains a stable range during transportation, it is often necessary to manually observe and record the display value of the pressure gauge to adjust the nitrogen pressure; the traditional inflation pressure gauge has a relatively single function, which is used to measure the pressure value of the equipment inflated and The generation of readings cannot meet the requirements of real-time acquisition of monitoring data, and there are many disadvantages, such as:

[0004] 1. The nitrogen pressure value in the transformer cannot be saved in real time during transportation;

[0005] 2. The sudden pressure value cannot be observed and saved in time;

[0006] 3. The pressure value is too large or too small to report to the police in time;

[0007] 4. Failure of the monitoring device itself cannot be detected in time;

[0008] The above-mentioned problems lead to the fact that the data observed during the transportation cannot really guarantee the quality of the transformer transportation, which brings inconvenience to the transportation of large transformers
