How to prevent dry-type transformer arc triggered arc short circuit

Do a good job of fan spare parts management, found fan failure timely replacement, to ensure that the fan runs normally, good heat dissipation.

Strengthen the daily inspection, especially the dry-type transformer cooling fan inspection must be careful and serious, you can observe the way the fan fins, to confirm that its operation is normal!

Dry-type transformer generally with shell, need to pay attention to the shell heat sink hole cleaning, in order to facilitate the shell within the transformer heat generated can be effectively dispersed.

Improve the function of dry-type transformer over-temperature trip. Dry-type transformer temperature controller have over-temperature trip line, output to the transformer switchgear, over-temperature will be transformer switch trip, realize the temperature protection of the transformer. Some users are not wired, or not put into the trip. In the event of transformer over-temperature phenomenon, will not normal operation phenomenon, evolved into transformer burned out accident.
