Basic Introduction:

Station transformers, also known as auxiliary transformers or station-use transformers, are essential equipment in power systems, used within substations to supply power to auxiliary devices. They typically take power directly from the busbar to provide the necessary AC power for various devices within the substation. They are usually designed as dry-type or oil-immersed transformers, with the appropriate type selected based on specific needs and application scenarios.

Main Functions:

The primary function of station transformers is to provide AC power to key equipment within the substation, such as protection screens, energy storage motors in high-voltage switchgear, SF6 switch energy storage, and on-load voltage regulation mechanisms of main transformers. These devices require a stable power supply for normal operation. Station transformers also supply charging services to DC systems, ensuring the stability and reliability of the DC system. Additionally, they provide power for living facilities within the substation, ensuring the smooth operation of both production and daily life within the substation.

Technical Features:

Our company’s station transformers are primarily used in ultra-high voltage AC/DC stations, 500kV and other large substations, and feature high insulation strength and protective functions to ensure stable operation in complex and variable grid environments. Additionally, some high-end models of station transformers are equipped with temperature monitoring and protection systems, which automatically activate protective mechanisms when overheating occurs to prevent equipment damage.

Application Areas:

Station transformers are widely used in various types of substations, whether in urban or rural power grids. They are also commonly found in industries such as power, petroleum, chemicals, and metallurgy. These industries require high stability and reliability of the power supply, and therefore rely on high-performance station transformers to ensure the proper operation of their power systems.
