Rectifier transformer The rectifier transformer is used to reduce the primary high voltage to the input voltage suitable for the intermediate frequency power supply. The equipment uses a special high-impedance oil-immersed self-cooling rectifier transformer, and its model is ZS series. The transformer uses 10KV for the primary voltage and 380V for the secondary voltage . The rectifier transformer is equipped with a gas relay and an oil temperature relay meter, which can be interlocked with the high voltage cabinet. When the transformer has gas or oil temperature exceeds the standard, it can automatically cut off the high voltage input and issue an alarm. | ||||||
