How to Make Better Use of rectifier transformer?

rectifier transformers are special types of transformers that are designed for rectification systems. Rectification is the process of converting alternating current (AC) to direct current (DC), which is often required for various industrial applications, such as aluminum electrolysis, electric arc furnaces, traction substations, and high-voltage direct current (HVDC) transmission systems. In this article, we will introduce the features and advantages of rectiformers, and provide some tips on how to use them effectively.

What are the features of rectifier transformers?

rectifier transformers are different from ordinary transformers in several aspects. First, they have to withstand high currents and harmonics that are generated by the rectifier devices, such as diodes or thyristors. Second, they have to provide a stable and adjustable output voltage for the rectifier system, which may require a built-in or separate voltage regulation unit. Third, they have to match the phase shift and pulse number of the rectifier system, which may require different winding configurations and connections.

What are the advantages of rectifier transformers?

rectifier transformers have several advantages over other types of transformers or power converters. First, they can provide high power and high efficiency for the rectification system, which can reduce the energy consumption and operating costs. Second, they can improve the power quality and reliability of the rectification system, which can reduce the harmonic distortion and voltage fluctuations. Third, they can offer flexibility and customization for different applications and requirements, which can optimize the performance and functionality of the rectification system.

rectiformers have been widely used in various industries for decades, and have proven their reliability and durability. They have also been constantly improved and innovated by manufacturers to meet the changing needs and challenges of customers. For example, Hitachi Energy has built more than 600 rectifier transformers in the last 20 years, with a total installed base of over 20,000 MVA. They have also developed a single tank solution for applications up to a rating of approximately 160 MVA.

How to use rectifier transformers effectively?

1. Choose the right type and size of rectifier transformer for your application. You need to consider the power rating, voltage level, current rating, pulse number, phase shift angle, winding configuration, cooling method, insulation level, etc.

2. Install and maintain the rectifier transformer properly. You need to follow the manufacturer's instructions and recommendations for installation, commissioning, testing, operation, maintenance, inspection, etc.

3. Protect the rectifier transformer from overloading, overheating, short-circuiting, lightning strikes, etc. You need to use appropriate protective devices and measures to prevent damage or failure of the transformer or the rectifier system.

rectifier transformers are essential components of many industrial applications that require DC power supply. By understanding their features and advantages, and by following some useful tips on how to use them effectively,you can make better use of them and benefit from their value.
