Transformers are inductively coupled electromagnetic devices that transfer electrical energy between circuits. This means they regulate the voltage. Transformers can pattern, convert, isolate, and increase and decrease current at various power levels. The voltage level depends on the ratio of the windings in the primary coil to the windings in the secondary coil.
As more and more substations are built in residential and commercial areas, transformer noise becomes very prominent. The transformer noise level has become an important indicator to measure the design and manufacturing level of transformer manufacturers.
Under the working condition of load current, the main source of transformer vibration and noise is the electromagnetic force of the winding. Considering the noise propagation path, the source of vibration and noise, the propagation path and corresponding reduction measures are studied.
The upstream industries of the power transformer manufacturing industry are raw materials such as silicon steel sheets, copper, aluminum, and other non-ferrous metals. Transformer raw materials constitute the main cost of the industry. For general power transformers, silicon steel accounts for 35% of the total cost of raw materials, copper accounts for 30%, insulating materials account for 15%, plates account for 10%, and other materials account for 10%.
Transformer is heavy industry and light industry, and the cost of materials accounts for more than 60% of the final cost price of the entire product.
The test pass rate of the transformer industry is lower than that of any industry in the light industry. The production enterprise should regard quality as the lifeline of enterprise development and put it in the first position of enterprise development. It is necessary to establish a complete quality assurance system and responsibility mechanism, effectively strengthen quality self-discipline, increase technological innovation, and continuously improve the quality level of power transformer products.
When designing transformers, SCIENTEK ELECTRICAL suppliers will consider application specifications. Since the number of windings directly determines the voltage transmitted through the magnetic field, the manufacturer of SCIENTEK ELECTRICAL will determine the number of windings installed according to the required voltage.
