The dry-type transformer follows certain rules in the process of adjusting the voltage. For the voltage of the dry-type transformer is constantly changing, the dry-type transformer can adjust the relevant voltage, so how to adjust the voltage of the dry-type transformer what about? Anhui Dali Xiaobian will teach you how to adjust.

The adjustment of the dry-type transformer tap changer (in other words, the gear position) can change the size of the secondary output voltage of the dry-type transformer. Generally, the tap changer is located on the top of the dry-type transformer. It is used to change the primary winding tap of the dry-type transformer, thereby changing the voltage ratio and adjusting the secondary voltage. The tap changer is divided into on-load transformers. There are two types of no-load transformer and no-load transformer, there are three positions of I, II, and III. The relative transformation ratio of the third position of 0kV dry-type transformer is 10.5/0.4, 10/0.4, 9.5/0.4. It is necessary to check and accurately measure the contact resistance of the gear switch (that is to say, resistance measurement), otherwise the dry-type transformer will be damaged if the adjustment is not good. Because your dry-type transformer has a high input switching power supply voltage, you can choose the first grade (10.5/0.4) to exceed the demand.

The above is the general adjustment of the voltage of dry-type transformers. If you have any questions, please contact the editor.
