Tips: How to adjust the transformer gear?
When adjusting the transformer gear, according to the output voltage level, adjust the tap switch to the corresponding position.
The steps to adjust the tap changer are:
1. Disconnect the transformer load, open the high-voltage drop-out fuse with an insulating rod, unscrew the protective cover of the transformer tap switch, and place the positioning pin in the neutral position.
2. When shifting gears, adjust the tap switch to the corresponding position according to the output voltage. When the voltage is too low, switch to the low-voltage gear, and when the voltage is too high, switch to the high-voltage gear.
3. After adjusting the gear, use a DC bridge to measure the DC resistance of each phase winding and check whether the DC resistance between the windings is balanced. If the phase-to-phase resistance difference is greater than 2%, it needs to be re-adjusted. Otherwise, the static and moving contacts will generate heat or even discharge due to poor contact and damage the transformer.
