Scope

This part of GB/T 3859 specifies the characteristics of converter transformers that differ from general-purpose power transformers.
It should be noted that when rectifier transformers are in operation, non-sinusoidal currents typically flow. In single-pulse connections, the current of each valve-side winding contains a DC component, which requires special attention during design and testing. In some cases, external short circuits and component failures can generate abnormal stresses, making special design measures necessary.
The voltage waveforms of some types of transformers during normal operation are non-sinusoidal. Their iron core losses are determined based on a sinusoidal voltage that is equal to the arithmetic average of the voltage half-cycle during operation and the fundamental frequency.
This part applies to converter transformers and reactors used in conjunction with power converter equipment specified in GB/T 3859.1. In all other aspects, if the national standard "Power Transformers" does not conflict with this part, the rules specified therein also apply to converter transformers.
