Chemical machinery equipment network hotspots pay attention to chemical machinery equipment transformers
The 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 features are: voltage converting, current conversion, impedance conversion, an isolated, regulated (magnetic saturation of the transformer) and the like

Transformers can be divided into distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, electrical test transformer box change, angle transformer, heavy-current transformer, excitation transformer

Among them, dry-type transformer refers to a transformer in which the iron core and windings are not immersed in insulating oil.
The structure is the same as that of an ordinary transformer, and it is mainly composed of iron core and windings
.
It realizes cooling through air convection, and has the characteristics of flame retardant, flame retardant, fireproof, explosion-proof, and environmental protection.
It is safe and reliable to use, easy to install and maintain, and can go deep into the load center

.
From the comparison of comprehensive technical and economic performances such as low noise, energy saving, fire protection, saving soil construction cost, operation and maintenance management fees and up to 30 years of life, dry-type transformers have shown their obvious advantages, so they are widely used in high-rise buildings, subways, Stations, airports, hospitals, petrochemical companies, and mine interiors
.
.
In recent years, the rapid development of the new energy power generation industry has brought better development space for transformers, and has also become an important direction for transformer manufacturers to seize market segments and expand their business scope
.
.
Data show that in 2019, China's dry-type transformer output is about 273 million kVA, and the annual compound growth rate of output from 2015 to 2019 is about 5.
50%.
It is expected that China's dry-type transformer output will reach 302 million kVA in 2021
