Phase-Shifting Rectifier Transformer


The dry type rectifier phase-shifting transformer is a kind of VPI dry type transformer, it is also the multi winding transformer, this dry type rectifier transformer realizes the soft start of high-power high-voltage motors, reduces the impact on the power grid and equipment wear greatly improves the current waveform on the grid side and eliminates the harmonic pollution of the power grid. The feeder, circuit breaker, and transformer run beyond the nameplate capacity caused by reactive power, improving voltage regulation, and suitable for induction motors with low synchronous speed. The phase-shifting transformer is mainly installed together with MV VFD. So this series of dry-type rectifier transformers are widely used in electric power, petroleum, chemical industry, metallurgy, municipal water supply, sewage treatment, textile, paper, pharmaceutical, coal, cement, rolling mill (steel mill), and other industries.

Phase-Shifting Rectifier Transformer Product Features

PRODUCT FEATURES

The HV & LV coils are made of Nomex products, after several times (impregnated) impregnating by H-class solvent-less varnish in the VPI vacuum impregnating equipment, and then solidified at high temperature to reduce partial discharge.

After (optimizing the heat dissipation layout) optimization of heat dissipation layout and high-quality material application, the service life can be expanded up to 30 years. The product is grade H (180) grade, with the main insulation of grade C, which enables it to have a large overload margin and good short-circuit resistance.

The core material is recyclable, and Nomex Paper will not release toxic substances when burning. The adaption of insulation materials is strictly controlled, all of which shall be UL certified materials to reduce environmental pollution.

The product has high efficiency and low loss. The harmonic generated by the motor is reduced to protect the grid from pollution.

Based on ISO-9000, fully absorbed and introduced lean production concept, we established 50 lean improvement quality criteria (LS). Each process and position has been provided with operation instructions and standardized operations criteria to implement the production plan, through timely management (SIM) to improve communication efficiency and continuously shorten delivery time. TPS with the core of production process management (MPS) has gradually been developed by connecting sales, materials, planning, supply chain, services ,etc.
