The working principle and architecture of dry-type transformers

Dry-type transformers are important transformers that we use constantly. Dry-type transformers greatly promote the continuous development of production and life. Dry-type transformers are also constantly carried out in our daily life, and during the operation and use of dry-type transformers, it is necessary to understand the technology and principle of dry-type transformers. This is the basis for using dry-type transformers, so how much do you know about the structure and principle of dry-type transformers? Let's find out with the editors of the dry-type transformer factory:
Dry-type transformer construction
Dry-type transformers mainly consist of an iron core, consisting of silicon steel plates and epoxy-coated coils. The insulated tube is placed between the high-voltage coil and the low-voltage coil to increase electrical insulation, and the coil is supported and constrained by a pad for anti-loosening properties.
Structural performance: performance solid insulated package winding and unencapsulated winding ##绕组: Among the two windings, the higher voltage is the high voltage winding, and the low voltage is the low voltage winding. From the relative position of high-voltage windings and low-voltage windings, high voltage can be divided into concentric and overlapping, concentric windings are simple and easy to manufacture, all using this structure.
The overlapping type is mainly used for special transformers.
Dry-type transformer principle
Dry-type transformers work on the same principle as other transformers. It follows the physics of the voltage technique required for electrical and magnetic coupling: when current flows through the wire, it will generate a changing magnetic field or the surrounding magnetic field, the magnetic field fluctuates around the wire and generates current in the wire, there will be a fluctuating magnetic field in the second and first lines, and the induced current will flow in the second line. Thus, the current passes through both wires from the first and second wires without actual contact.
