The ZSG (ZB) series three-phase dry-type rectifier transformer is an important component of rectifier equipment, which, together with various rectifier devices, forms a rectifier circuit system. To convert AC power into DC power, a rectifier transformer first converts the voltage of the AC power grid into a voltage of a certain magnitude and number of phases, and then outputs it to the DC drive equipment through a rectifier device (rectifier).
A rectifier transformer is a power transformer used for rectifier equipment. Its task is to convert AC into a voltage of a certain size and number of phases, and then rectify it through rectifier components,
To meet the requirements of DC output. In addition, rectifier transformers also have the following functions: isolating rectifier equipment from the power grid circuit, ensuring equipment and personal safety, limiting short-circuit current,
Reduce the electromagnetic interference between rectification equipment and the power grid or other parallel operating rectification equipment, and suppress the current rise rate of rectifier components such as thyristors. The product is suitable for electrification (electrolysis)
Industries such as frequency conversion, traction, direct current transmission, electroplating, spraying, electrical processing, charging, excitation, transmission, electrostatic precipitator, and general industrial rectifier power supply.
