Dry-type transformer is cut off like this

In many cases, dry-type transformers need to be powered off during operation, and such practical operation is a difficult problem. In fact, there are many methods and procedures for the actual operation of dry-type transformers, so what are the power-off countermeasures that dry-type transformers need to take? Anhui Dali Xiaobian will bring you a detailed understanding.

Anhui vigorously said that the power failure of dry-type transformers:

1. Check that the transformer and the backup power supply are the current system, and the backup power supply is in an emergency state.

2. Three-phase five-wire 98K power switch for ground backup power supply, check the ring.

3. Disable the BZT machinery and equipment.

4. Pull off the 87K power switch on the bottom voltage side and the 73K power switch on the high voltage side of the ash removal transformer.

5. Check that the 87K power switch is on, and pull out the 87K power switch.

6. Check that the 73K power switch is in the open position, and straighten the car power switch to the inspection position.

7. Remove the AC power during operation of the 73K and 87K power switches.

8. Arrange management measures reasonably according to the work ticket.

The above is the dry-type transformer power-off operation introduced by Anhui Dali Xiaobian.
