Devido aos curtos-circuitos, 220v transformadors often require a long time to maintain. In order to prevent the high-frequency transformador from getting wet, two measures can be taken:
(1) Before the end of work, buckle the cover of the high-frequency transformador, evacuate the high-frequency transformador with a vacuum pump, remove the free water on the surface of the high-frequency transformador body, and remove the vacuum with dry nitrogen or dry air when working the next day. Generally, high-frequency transformadors 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 transformadors after work every day, and dry the high-frequency transformador/customied transformador com spray de óleo quente após a conclusão de todo o trabalho, o que geralmente leva de 7 a 10 dias.
