ZHSTB-125000/220kV oil-immersed self-cooling rectifier transformer is a typical product of 220kV large-capacity rectifier transformer. Adopting oil-immersed self-cooling mode, the structure is compact, the heat dissipation efficiency is high, no additional cooling equipment is required, and the operation and maintenance cost is low.
The product design fully considers the harmonic characteristics of the rectifier system, and adopts a special winding connection method and shielding structure to effectively suppress harmonic interference and improve power quality. The iron core adopts a multi-stage stepping joint structure to reduce no-load loss and noise level.
Applicable to large aluminum electrolysis, electrochemical metallurgy, high voltage DC drive and other industrial fields. This product meets national standards: GB1094.1-2013, GB1094.2-2013, GB1094.3-2003, GB1094.5-2003 and GB/T 6451-2015 and other relevant standards.
