Baoding dry type transformer is a transformer with iron core and windings not impregnated in insulating oil. The cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When natural air cooling, baoding dry type transformer can run continuously for a long time under rated capacity. When forced air cooling, transformer output capacity can be increased by 50%. Suitable for intermittent overload operation, or emergency overload operation.

Baoding dry type transformer wiring is what? Take a look below:

1. The "input" and "output" terminals of short-circuit transformers are tested with megohm meters for their insulation resistance against ground wires. When measured with a 1000V megohm meter, the resistance is greater than 2M ohms.

2. The cross-section wiring of transformer input and output power lines shall meet the requirements of current value; It is advisable to configure according to 2-2.5a /min2 current density.

3. The input and output three-phase power lines shall be connected with phase A, B and C in the colors of yellow, green and red of the transformer junction board bus. The neutral neutral zero line shall be connected with the neutral zero line of the transformer transformer. Check the input and output lines to make sure they are correct.

4. Power on without load first, observe that the test input and output voltage meet the requirements. At the same time, observe whether there is abnormal phenomenon such as abnormal sound, ignition, peculiar smell inside the machine. If there is any abnormality, please immediately disconnect the input power.

5. When the no-load test is completed and normal, the load can be connected.
