[Dali Transformer] How is the dry-type transformer adjusted?

There are many various gears of dry-type transformers. The gears of dry-type transformers are constantly adjusted, and only the gears can be adjusted continuously. In that case, the speed and high and low speed of dry-type transformers are It will show up as soon as possible. So how to adjust the gear shift of the dry-type transformer? Let's follow the editor of Dali Transformer to see how to adjust the gear.

First power outage, disconnect the power distribution equipment. After the bottom-voltage side of the dry-type transformer is loaded, use an insulating rod to open the high-voltage side drop-out fuse, and then take protective measures. Then twist open the maintenance cover of the tap power switch on the dry-type transformer, and place the positioning pin in the neutral position. When adjusting the gear position, the tap power switch should be adjusted to the opposite position according to the output working voltage. The basic elements of adjusting the tap power switch are: when the output working voltage of the dry-type transformer is less than the control value, the tap power switch position should be adjusted from The I gear is adjusted to the II gear, or the II gear is adjusted to the III gear. Generally, dry-type transformers can only change the tap under the condition of power failure, and can not change the tap position with load. The working voltage deviation does not exceed the allowable range.

The above is the gear shifting method of dry-type transformers introduced by the editor of Dali Transformer.
