بسبب الدوائر القصيرة ، 220v محولs often require a long time to maintain. In order to prevent the high-frequency محول from getting wet, two measures can be taken:
(1) Before the end of work, buckle the cover of the high-frequency محول, evacuate the high-frequency محول with a vacuum pump, remove the free water on the surface of the high-frequency محول body, and remove the vacuum with dry nitrogen or dry air when working the next day. Generally, high-frequency محولs 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 محولs after work every day, and dry the high-frequency محول/customied محول باستخدام رذاذ الزيت الساخن بعد الانتهاء من جميع الأعمال ، والتي تستغرق عمومًا من 7 إلى 10 أيام.
