ZPSG Dry-type rectifier transformers

PRODUCT DESCRIPTION

 

Dry-type rectifier transformers are a kind of devices specially providing multiphase rectifier power supply for MV and HV frequency converter. 

At present, the Large-capacity high-voltage level inverter has been used to any appreciable extent with the rapid development for high-voltage variable frequency control technology. 

Adoption the speed control of Dry-type rectifier transformers can reduce energy consumption and production costs. 

Our successfully company developed a series of multi-phase based on many years of Dry-type rectifier transformers production and design technology. This kind products have been used in national key project. 

Adopt the principle of phase shift of triangle and by the secondary winding of several different phase shift angles. They can form the rectifier transformers; the equivalent phase number is 9-phase, 12-phase, 15-phase, 18-phase, 24-phase and 27-phase etc.

HV side directly of transformer connected into the high-voltage grid and it's LV side has a plurality of three-phase windings, it according to the 0°、θ°、…、(60-θ)° to show the Yanbian triangle connection with each low-voltage three-phase windings from the LV side of transformer.

 

 Adopt the principle of phase shift of triangle and by the secondary winding of several different phase shift angles. The rectifier power supply can effectively offset the harmonious wave by combination of frequency conversion power unit. The product is mainly used in the boiler fan, water supply system of the power plant and in the automation system of metallurgical and chemical industries and municipal project.

 

 

Taking various types of HV and LV frequency converters into enough consideration, we have carefully developed and prepared ZPSG type NOMEX insulation dry-type rectifier converter. The product includes 9-phase, 12-phase, 15-phase, 18-phase, 24-phase and 27-phase etc. self-cooling and air cooling types of rectification frequency conversion transformers.

 

There are variety morphological structure of Multi-phase rectifier transformer winding and the outlet size can be customized as customers' installation request.
