En raison de courts-circuits, 220v transformateurs often require a long time to maintain. In order to prevent the high-frequency transformateur from getting wet, two measures can be taken:
(1) Before the end of work, buckle the cover of the high-frequency transformateur, evacuate the high-frequency transformateur with a vacuum pump, remove the free water on the surface of the high-frequency transformateur body, and remove the vacuum with dry nitrogen or dry air when working the next day. Generally, high-frequency transformateurs can be put into operation directly after 24 hours of hot oil circulation after maintenance.
(2) Do a good job of rainproof measures for high-frequency transformateurs after work every day, and dry the high-frequency transformateur/customied transformateur avec un spray d'huile chaude une fois tous les travaux terminés, ce qui prend généralement 7 à 10 jours.
