A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage transformation, current transformation, impedance transformation,

Transformer is an important equipment in the power industry. According to the current development status and characteristics of my country's transformer manufacturing, which field should it develop in order to obtain more support from national policies, so as to embark on the fast lane? "The most

Dry-type transformers are widely used in local lighting, high-rise buildings, airports, terminal CNC machinery and equipment, etc. Simply speaking, dry-type transformers refer to transformers whose iron cores and windings are not immersed in insulating oil.Advantages and disadvantages of dry-type

1. Oil leakage from weldingMainly due to poor welding quality, there are defects such as virtual welding, de-soldering, pinholes and blisters in the welding seam, the power transformer is covered with flux and paint when it leaves the factory, and hidden dangers are exposed after operation.

The construction of transformers in power engineering construction can be described as a very important part. Among them, we often hear dry-type transformers (referred to as dry-type transformers) and oil-immersed transformers (referred to as oil-type transformers). What are the main differences
