Rectifier transformer
he rectifier transformer is used to reduce the primary high voltage to the input voltage suitable for the intermediate frequency power supply. he device uses a dedicated high-impedance oil-immersed self-cooling rectifier transformer, the model isZSseries.he primary voltage of the transformer is10KVａnd the secondary voltage is380V.he rectifier transformer is equipped with a gas relay and a oil temperature relay table, which can be interlocked with the high voltage cabinet. When the transformer has gas or oil temperature exceeding the standard, the high voltage input can be automatically cut off and an alarm is issued.
