ZS series oil-immersed rectifier transformer

Description

They are widely used in electrolysis, electrochemical, driving, traction, static de-dusting, DC power transmission fields where rectification power source is necessary. A rectifier transformer is used for power supply of rectifying devices, most industrial DC power sources is transformed from an AC network via rectifier devices consisting of a rectifier transformer and a rectifier. It is widely used in electrolysis, electrochemical, traction, driving, DC transmission, frequency conversion and rectified power source fields. According to user's requirements, the secondary winding phase difference can be designed to 30° , 15° , 7.5° , for rectification of 6-phase, 12-phase, 24-phase and 48-phase.
