1、定期清除電源柜內積塵 1. Remove dust from the power cabinet regularly 尤其是可控硅管芯外部，要用酒精擦除干凈。運行中的變頻裝置一般都有專用機房，但實際作業環境并不理想在熔煉鍛壓工序，粉塵很大震動強烈。在透熱淬火工序，裝置廠靠近酸洗磷化等作業設備，有較多腐蝕性氣體，這些都會對中頻電爐相關裝置的元件起到破壞作用，降低裝置的絕緣強度在積塵較多時，往往會發生元件表面放電現象，因此必須注意經常清洗工作，防止故障發生； In particular, the silicon controlled silicon tube core should be cleaned with alcohol. The frequency conversion device in operation usually has a special machine room, but the actual working environment is not ideal in the smelting and forging process, and the dust is very strong. In heating quenching process, the device factory near the work equipment, such as pickling phosphating more corrosive gas, these will be for the intermediate frequency electric furnace related device components damage effect, decreases the insulation strength of the device are too many in the dust, the components surface discharge phenomenon can occur, so must pay attention to often clean work, prevent failure; 2、定期檢查水管接頭扎結是否牢靠 Check the connection of the water pipe regularly 使用自來水井水作為中頻電爐裝置的冷卻水源時，易積存水垢，影響冷卻效果。在塑料水管老化產生裂紋時，應及時更換裝置。在夏天運行時采用自來水井冷卻往往容易發生凝露現象，應該考慮使用循環水系統，凝露嚴重時應該立即停止運行； When water well water is used as the cooling water source of medium frequency furnace, it can deposit scale and influence the cooling effect. When the plastic water pipe age cracks, should replace the device in time. In the summer, when the water is used to cool the water, it is easy to get the condensation phenomenon. The circulating water system should be considered, and the operation should be stopped immediately when the condensation is serious. 3、定期更換或清洗中頻電爐相關設備的關鍵部件 3. Regularly replace or clean the key parts of the equipment in the intermediate frequency furnace 4、定期對裝置進行檢修 4. Check the equipment regularly 對裝置各部件的螺栓和緊固接觸器繼電器的觸頭要進行定期檢查，若出現松動或接觸不良現象，均應及時修理更換，不能勉強使用，防止引起重大事故。 Every parts of device bolt fastening contactor and relay contactor to conduct regular inspection, if appear, loosening or poor contact, shall be promptly repaired change, can not be forced to use, to prevent major accidents.
