A causa di cortocircuiti, 220v trasformatores often require a long time to maintain. In order to prevent the high-frequency trasformatore from getting wet, two measures can be taken:
(1) Before the end of work, buckle the cover of the high-frequency trasformatore, evacuate the high-frequency trasformatore with a vacuum pump, remove the free water on the surface of the high-frequency trasformatore body, and remove the vacuum with dry nitrogen or dry air when working the next day. Generally, high-frequency trasformatores 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 trasformatores after work every day, and dry the high-frequency trasformatore/customied trasformatore con spruzzo di olio caldo dopo che tutto il lavoro è stato completato, che richiede generalmente 7~10 giorni.
