Dry type transformer is an important type of transformer, at the same time, it will often appear in the process of using the noise situation, for the noise of dry-type transformer, is an important type of fault, in normal use, we should pay attention to the main reasons for the noise of dry-type transformer, next we analyze the main reasons for the noise Bar:
The possible reasons for high noise of dry-type transformer are as follows:
1. Voltage problems lead to
High voltage will make the transformer over excited, and the noise will increase and sharp, which will directly affect the noise of the transformer.
2. Resonance problems of fan, shell and other parts
The resonance of fan, shell and other parts will produce noise, which may be mistaken for the noise of transformer.
3. Problems with installation lead to
Improper installation will aggravate the vibration of the transformer and amplify the noise of the transformer.
4. The influence of installation environment leads to
The operating environment affects the noise of the transformer, and the unfavorable environment increases the noise of the transformer by 3dB ~ 7dB.
5. The problem of bus bridge vibration leads to
Due to the large current passing through the parallel bus, the bus vibrates due to the leakage magnetic field. The vibration of the bus bridge will seriously affect the noise of the transformer, making the noise of the transformer increase by more than 15dB, which is difficult to judge, and the general users and installation units will mistakenly think it is the noise of the transformer.
The main reason for the noise of dry-type transformer is introduced above. For the noise problem of dry-type transformer, what other different problems do you have? Please contact our manufacturer and our website for detailed understanding!
