Feature of Three Phase Five Limb Rectifier Transformer

This series of products have the features of smooth waveform, low harmonic pollution, good heat dissipation, strong thermal impact resistance, high over-load capacity, low loss, low noise and easy maintenance. Worked as the isolated power supply in the high-voltage variable-frequency speed regulating device, this series of products can be matched with the high-voltage variable-frequency speed regulating device, so as to realize the multiple technology and effectively suppress the harmonic content.

Application of Three Phase Five Limb Rectifier Transformer

It is suitable for electrical industry, petroleum, chemical industry, metallurgy, municipal water supply, waste water treatment, textile, paper making, pharmaceuticals, coal, cement, rolling mill (steel factory) and other industries.

Structure of Three Phase Five Limb Rectifier Transformer

a. The core material is made of high-quality cold-rolled silicon steel sheet, which is carefully laminated in full 45diagonally;

b. Insulation materials of transformer are H level with the 20-year service life time the same as transformers;

c. The structure of coil is non-encapsulated with excellent property of flame retardant;

d. The insulation materials on wires are with H class insulation. And the products have been painted with 3-proofings lacquer and cured under high temperature which all can strengthen the anti-short circuit ability;

e. The shell of transformer is made of high-quality steel sheet;

f. The inlet and outlet wires of transformer are generally connected from bottom. Cable holes are set on the base of transformer box, and a device is set to fix the cable.
