ry transformers, knowledge that you don't necessarily know!
A dry-type transformer is a type of transformer that is not impregnated with an insulating oil core and winding. The cooling method is divided into natural air cooling (AN) and forced air cooling (AF). When the natural air is cold, the dry transformer can continuously run the rated capacity. The output capacity of the transformer can be increased by 50% when the air is forced to cool. Can be used for intermittent overload operation or emergency overload operation.
What is the connection mode of the dry transformer? A look at:
1. The "input" and "output" terminals of the working short-connected transformer test its insulation resistance and ground wire. When measuring 1000V, the resistance value is greater than 2M ohms.
2. The distribution of transformer input and output power line should meet the requirement of its current value; 2-2.5 a/min2 current density is appropriate.
3, input, output, three-phase power supply cord shall, in accordance with the transformer wiring board bus bar color is yellow, green, and red respectively. A, B, C phase, neutral zero line should be connected to the transformer neutral zero line and grounding line and transformer shell (such as transformer has A signal corresponding to the cases should be connected to the ground). Check the input/output line and confirm correct.
4. Test input and output voltage meet requirements. At the same time, observe whether there are abnormal phenomena inside the machine. If there is any abnormality, please disconnect the input power immediately.
5. Load can be accessed when the no-load test is complete and normal.
