Description:
Rectifier transformer is designed as a single entity for converting alternating current into direct current. It is a piece of power system equipment rather than an electronics component. Rectiformers are used for supplying power to different fields of ESP (electrostatic precipitator). It is commonly found in electrowinning operations. Rectifier transformers are combined with a diode or thyristor rectifier. The applications range from large aluminium electrolysis to various medium-size operations, such as electrowinning industry, chlor-alkali industry, aluminum industry, DC arc furnace industry, etc. A rectiformer may have a separate voltage regulation unit. Due to a large variety of applications, they can have various designs up to a combination of voltage regulating. Rectifier transformers are used for industrial processes which require a significant direct current (DC) supply. Typical processes would include DC traction, electrolysis, smelting operations, large variable speed drive trains, etc. CORROCO, with more than ten years' production experience, can provide top-quality rectiformers and full scope of services for clients.
With different connection, rectifier transformers can be classfied as below:
1. Three-phase bridge commutation circuit
2. Cophase counter parallel three-phase bridge commutation circuit
3. Double backward star & balance reactor commutation circuit
4. Cophase counter parallel double backward star & balance reactor commutation circuit
