This part of GB/T 18494 specifies the technical requirements, design, and testing of power transformers and reactors assembled in semiconductor converter equipment. This part is not applicable to conventional AC distribution transformers This section is applicable to power converters of any capacity. Typical applications include: electrolytic thyristor rectifiers, electrolytic diode rectifiers, high-power drive thyristor rectifiers, waste furnace thyristor rectifiers, and variable speed drive inverter diode rectifiers. This section also applies to the voltage regulating unit of step-down regulators or autotransformers. The maximum voltage of the equipment on the valve side winding shall not exceed 40.5kV This section is not applicable to transformers for high-voltage direct current transmission Although the complete set of converter equipment standards (such as GB/T
