What Is A Three-phase Transformer



Three-phase transformers are widely used in circuits with AC 50Hz to 60Hz and voltage below 660V. They are widely used in the import of important equipment, precision machine tools, mechanical and electronic equipment, medical equipment, rectifiers and lighting. Product input and output voltage level, the connection group, adjust the number and location of the tap (usually ± 5%), the distribution of winding capacity, the distribution of secondary single-phase windings, the use of rectifier circuit, whether the required band Shell, etc., can be carefully designed and manufactured according to the user's requirements.

In the three-phase transformerto establish a new centerline - grounding can solve the common mode interference in the power grid and other midline problems, three-phase transformer will be converted to three-wire △ Yt system four lines, plus shielding further eliminates the coupling by the transformer high frequency Pulse interference and noise, although shielded three-phase transformers can effectively prevent interference from various NGs (pulsed and high-frequency noise), the transformers must be correctly and properly grounded otherwise the common-mode interference will be ineffective.

Three-phase transformer conditions of use

1 for altitude: ≤ 5000m

2 Ambient temperature: -15 ℃ ~ +45 ℃

3 Relative humidity: ≤ 90%

4 Installation places should not seriously affect the strength of the transformer insulation gas, steam, chemical deposition, dirt, conductive dust and no other explosive combustible corrosive substances.

5 Those who do not meet the above conditions of use, should be negotiated with us

6 according to the user's requirements for careful design and manufacture.
