变压器的调压是通过旋转变压器开关切换变压器分接头来实现的，从而改变变压

The voltage regulation of the transformer is realized by switching the transformer tap through the rotary transformer switch, thereby changing the transformation ratio of the transformer. There are two switching methods: non-energized switch, called non-excited voltage regulation. The voltage adjustment range is usually within + 5%. The other is on-load switching, called on-load voltage regulation. The voltage adjustment range can reach + 30%. For transformers of 100kV and below, transformers with at least one-stage voltage should use on-load voltage regulation. In summary, the main transformer of this substation uses on-load voltage regulation.

The pressure adjustment of the transformer is achieved by rotating the transformer switch to switch the transformer connector, thus changing the ratio of the transformer. There are two kinds of switching: non-live switch, called no excitation pressure. The voltage regulation range is usually within a range of 5%. The other is to have load switching, called load-regulating. The voltage regulation range can be up to 30%. For transformers 100kV or less, transformers with at least one voltage should be load-regulated. In summary, the main change of this substation is load-regulated.

The voltage regulation of the transformer is realized by switching the tap of the transformer with a resolver switch, so as to change the transformation ratio of the transformer. There are two ways of switching: non electrified switch, which is called non excitation voltage regulation. The voltage regulation range is usually within + 5%. The other is on load switching, which is called on load voltage regulation. The voltage regulation range is up to + 30%. For transformers of 100kV and below, transformers with at least one level of voltage shall adopt on load voltage regulation. In conclusion, the main transformer of the substation adopts on load voltage regulation.<br>
