First, the transformer startup steps

1 Check that the device meets the start conditions.

2 Check that the working power is normal and the position light is displayed correctly.

3 Thermal start conditions are allowed.

4 Soft operation Click the transformer closing button (or press the closing button in place), the position light indication is correct.

5 The starting current returns, the transformer works normally, and the startup is completed.

Second, the transformer operation steps

1 Minimize transformer load.

2 Soft-click the button to open (or press the button on the door), the switch is opened, the position indicator is correct, and the current is displayed to zero.

3 Check the transformer on the spot (not allowed to reverse)

4 Decide whether to power off or transfer to standby according to the requirements.

Before the large-scale transformer is started, a special person should be assigned to the site to monitor the start-up situation, except in the case of an accident.

When the newly installed or repaired transformer is turned on in the remote operation, the motor should be monitored next to the motor until the speed rises to the rated speed and is normal.

Regardless of whether the DC transformer is started or stopped, a special person should be assigned to adjust the DC bus voltage in time.

The transformers should be started one by one. It is generally not allowed to start two or more transformers simultaneously on the same bus.

When the transformer starts the trip for the first time, it is not allowed to start again until the cause is found. If the insulation is good and needs to be restarted, it should be sent to someone to monitor and find the abnormality and immediately stop the transformer operation.
