Cause of loud noise of dry-type transformer

Dry-type transformer is an important type of transformer, at the same time, it will often appear the state of noise in the process of using. For the dry-type transformer, the noise becomes bigger, which is an important type of fault, in peacetime use to pay attention to the dry-type transformer of the main reasons for increased noise, and then we analyze the main reasons for increased noise it：

　　The possible reasons for the noise of dry-type transformer are as follows:
1, voltage problem, high voltage, will make the transformer over-excitation, loud and Sharp, directly seriously affect the noise of the transformer. 2. The resonance of the Fan, casing and other components causes the resonance of the Fan, casing and other components to produce noise, which may be mistaken for that of the transformer. 3, the installation of the problem, the installation will aggravate the transformer vibration, amplification of transformer noise. 4. The influence of the installation environment leads to the influence of the operating environment on the noise of the transformer, and the adverse environment increases the noise of the transformer by 3dB ~ 7DB. 5. The problem of Busbar bridge vibration is caused by the large current passing through the side-by-side busbar and the busbar vibration caused by the magnetic leakage field. The vibration of Busbar Bridge frame will seriously affect the noise of transformer, and make the noise of transformer increase more than 15dB, it is difficult to judge. The main cause of noise from dry-type transformers is the above mentioned. What other different problems do you have regarding the noise from dry-type transformers, please contact our manufacturers and our website for a detailed understanding of it!
