1、定期清除电源柜内积尘 1. Remove dust from the power cabinet regularly 尤其是可控硅管芯外部，要用酒精擦除干净。运行中的变频装置一般都有专用机房，但实际作业环境并不理想在熔炼锻压工序，粉尘很大震动强烈。在透热淬火工序，装置厂靠近酸洗磷化等作业设备，有较多腐蚀性气体，这些都会对中频电炉相关装置的元件起到破坏作用，降低装置的绝缘强度在积尘较多时，往往会发生元件表面放电现象，因此必须注意经常清洗工作，防止故障发生； 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、定期检查水管接头扎结是否牢靠 Check the connection of the water pipe regularly 使用自来水井水作为中频电炉装置的冷却水源时，易积存水垢，影响冷却效果。在塑料水管老化产生裂纹时，应及时更换装置。在夏天运行时采用自来水井冷却往往容易发生凝露现象，应该考虑使用循环水系统，凝露严重时应该立即停止运行； 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、定期更换或清洗中频电炉相关设备的关键部件 3. Regularly replace or clean the key parts of the equipment in the intermediate frequency furnace 4、定期对装置进行检修 4. Check the equipment regularly 对装置各部件的螺栓和紧固接触器继电器的触头要进行定期检查，若出现松动或接触不良现象，均应及时修理更换，不能勉强使用，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.
