Phase-shift Rectifier Transformer

Equipment Display

Overview

Our company can  produce dry type phase-shift  rectifier transformer  high   rated  voltage  up  to  35  kV and  capacity  up  to 15000kVA. The products are widely used in the field of petroleum, chemical, metallurgy, textile, coal, cement, rolling mill (steel mill)etc.

Feature of Phase-Shifting Rectifier Adjustable Voltage 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 Phase-Shifting Rectifier Adjustable Voltage 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 Phase-Shifting Rectifier Adjustable Voltage 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 25-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.

Parts Details

Product Workshop

ZTELECGROUP Transformer Company have extensive transformer design and site operation experience which enables us to accurately assess a transformer’s condition both pre and post failure.
These assessments can be conducted in the field or in the either of our world class facilities, depending on the size of transformer being assessed and the location of the subject transformer.

Typical transformer assessment services include:

Condition assessment in the field
Oil sampling and testing in conjunction with TJ|H2b Analytical Services
Specialist transformer testing using the latest equipment
Site failure investigation (field or factory)
