Transformer is an important device to stabilize the voltage and current in the circuit, and plays a key role in the power system. But for the transformer, it is also necessary to play a certain role in the work. The work of the transformer is a relatively complex and systematic engineering and technology. All its components are involved in the work, and all parts work together. In this way, the transformer can play a greater role in the work. In fact, the study of transformer mechanics has lasted for a long time.
The natural oscillation frequency of the winding depends to a large extent on the degree of compaction after installation, because the elastic coefficient of insulation is related to this. The tighter the pressure, the higher the natural oscillation frequency of the winding. Therefore, increasing the clamping force may increase or decrease the dynamic force, which is related to whether the natural frequency is close to or far from the forced oscillation frequency.
Up to now, the operation practice at home and abroad has proved that the dynamic stability damage caused by the short circuit of the transformer has a certain relationship with the calculation of the electrodynamic force and the calibration strength according to the static method during the design, which may also be the reason that has promoted the development of the research on the calculation method of the dynamic force and the vibration calculation of the transformer, and is still developing. At present, in China, in the design of medium and small transformers, the static force is generally used to calculate the electric force and check the strength, but this is not a big problem. For the design of large-capacity transformers, some transformer manufacturers have introduced programs based on dynamic force calculation from abroad, and relatively similar programs have been studied in China, which seems to have achieved good results, but these are all patents. However, it also shows that China has made good achievements in the calculation of transformer dynamic force and vibration.
The basic principle and various states of the transformer are complex and wonderful. It plays a large role in the circuit. Therefore, the transformer will be used more in the future and the market will be broader!
