Applications of Dry-Type Rectifier Transformers

Dry-type rectifier transformers are renowned for their excellent insulation, fireproof and explosion-proof performance, low maintenance cost, and strong environmental adaptability. These features make them the core equipment for stable power supply in numerous industries.

Industrial Manufacturing

1. Electroplating and Electrolysis Industry

Dry-type rectifier transformers are essential in electroplating and electrolysis processes. Electroplating requires precise control of DC voltage and current to achieve uniform deposition of metal ions. These transformers can stably convert AC power into DC power and adjust output parameters as needed. For example, in automotive parts electroplating, they provide a stable power supply for the electroplating tank to ensure coating quality meets standards.

The electrolysis industry also relies heavily on these transformers. In non-ferrous metal refining, they output high-current DC power to reduce metal ions. Their stable output and precise adjustment significantly improve electrolysis efficiency, reduce energy consumption, and enhance metal purity.

2. Metallurgical Industry

Metallurgical processes such as arc furnace steelmaking and non-ferrous metal smelting require a stable DC power supply. Dry-type rectifier transformers output high-voltage DC power to maintain stable arc combustion, speeding up the smelting process. In arc furnace steelmaking, the stable arc accelerates scrap steel melting and impurity removal, shortening the production cycle. Additionally, these transformers' excellent insulation and protection performance make them suitable for the harsh conditions of high temperature, dust, and strong electromagnetic interference in metallurgical workshops.

3. Chemical Industry

Special chemical reactions and electrochemical processes in chemical production often require DC power. For instance, in the chlor-alkali industry, dry-type rectifier transformers convert AC power into DC power for brine electrolysis to produce chlorine, hydrogen, and sodium hydroxide. In fine chemical synthesis, they accurately supply power to optimize reaction conditions and improve product yield and purity.

New Energy Field

1. Photovoltaic Power Generation

In photovoltaic power generation systems, dry-type rectifier transformers play a crucial role by converting the direct current generated by photovoltaic arrays into alternating current suitable for the power grid. Their wide voltage adaptability ensures stable high-quality AC output despite voltage and current fluctuations caused by light and temperature variations. This reduces energy conversion losses and improves power generation efficiency.

2. Wind Power Generation

Wind turbines output alternating current, which needs rectification and inversion for special applications or grid connection. Dry-type rectifier transformers convert unstable AC into DC in the rectification process. Their compact structure and strong environmental adaptability ensure stable wind power generation system operation under harsh natural conditions.

3. Energy Storage System

In battery energy storage systems, dry-type rectifier transformers enable bidirectional conversion between grid AC and battery DC. By accurately adjusting voltage and current, they protect batteries, extend their lifespan, and promote efficient energy exchange between the energy storage system and the power grid, enhancing new energy consumption capacity.

Rail Transit Field

1. Urban Rail Transit

Urban rail transit systems like subways and light rails demand highly stable power supply. Dry-type rectifier transformers convert AC power into DC power for train traction systems. Their fireproof and explosion-proof characteristics, low maintenance requirements, and suitability for confined spaces with high safety standards make them ideal for underground stations. They can also quickly respond to load changes to ensure smooth train operation.

2. High-Speed Railways

In high-speed railway traction substations, dry-type rectifier transformers convert high-voltage AC power into current suitable for trains. They offer high reliability, strong anti-interference capabilities, and adaptability to complex operating environments. Their intelligent monitoring functions assist operation and maintenance personnel in detecting and addressing potential issues promptly.

Data Center Field

With the advancement of information technology, data centers have increasingly stringent power quality requirements. Dry-type rectifier transformers provide stable DC power for servers and other equipment. Their efficiency and energy-saving features help reduce operating costs. Additionally, their intelligent management systems monitor power supply status in real-time to ensure safe data storage and rapid processing.
