Outstanding outstanding scientific research personnel to make our products become an independent school; credibility is the cornerstone of enterprises! The team of high-quality services so that you have no worry. Enterprise management is the fundamental! Digital management of our community clean and efficient! Below by Guangzhou world power voltage regulator power supply equipment company to share about several main parts of the transformer

The main parts of transformer:

( 1) the body: including iron core, winding, insulation member and lead.

( 2) pressure regulating device: tap switch, divided into off-circuit and on-load

( 3) tank and cooling device.

( 4) protection device: includes oil storage cabinet, safe airway, moisture absorber, gas relay, oil purifier and temperature measuring device.

( 5) insulating sleeve.

1 core transformer core is main magnetic circuit. Usually made with high Si content were 0.35 mm\0.3mm\0.27 mm, thickness, surface is coated with insulating paint for hot or cold rolling silicon steel sheet laminated iron core is divided into a core column and horizontal slice of two parts, a winding iron core columns; the closed magnetic path is the core structure of the basic form of core and shell type two

2 winding transformer winding is part of the circuit, it is with double wire insulated wire or enamelled round wire wound into. Transformer is the basic principle of the electromagnetic induction principle, the single phase double winding transformer as an example to illustrate the basic principle: when the primary side winding voltage plus the? 1, current flows? 1, in the core of it generates alternating magnetic flux? 1, the magnetic flux is called main magnetic flux in it, under the action of both sides, Winding Induction EMF respectively? 1, 2?, EMF formula is: E=4.44fN? M : E-- induction voltage effective value f-- frequency N-- turns? M-- main flux maximum value as a result of the two winding and a secondary winding turns, EMF E1 and E2 have different sizes, when omitting resistance compressive after falling, voltage? And 1? 2 size is also different. When the two sides of the transformer no-load, one side only the main magnetic flux flowing through the current (? 0), the current known as the excitation current. When the two side load flow through the load current? 2, also in the core of magnetic flux, tries hard to change the main magnetic flux, but a constant voltage, main magnetic flux is constant, one side will flow through the two part of the current, a part of the exciting current? 0, one part is used to balance 2,? So this part of the current 2 as change?. When the current multiplied by the number of turns, is the magnetic potential. The role of balance is essentially the magnetic potential balance effect, transformer is through the magnetic potential balance effect achieved by the one or two side of the energy transfer. Transformer technical parameters for different types of transformer has the corresponding technical requirements, can be the corresponding technical parameters. Such as power transformer main technical parameters are: the rated power, rated voltage, rated frequency and voltage ratio, working temperature rating, temperature, voltage regulation rate, insulation and moisture resistant, for general low frequency transformer main technical parameters are: the transion ratio, frequency characteristics, nonlinear distortion, magnetic shielding and electrostatic shielding, efficiency.
