1.The generator outlet,neutral wire connection part should be reliable,in the operation of the unit should be conducted on a regular basis excitation variable to static excitation device of the split phase cable,static excitation device to the rotor slip ring cable,rotor slip ring high efficiency electric motor for infrared imaging temperature measurement inspection.2.Regular check electric braking action contact breaker contact situation,found that the compression spring loose ac three phase
motoror single touch refers to touch with other parallel problems should be handled in time.3.The generator insulation overheat alarm,should analyze the causes,and,when necessary,to eliminating downtime.
4.The old and new production machine maintenance,should pay attention to check the stator iron core compaction and tooth pressure refers to the presence of partial pressure,especially on both ends of the teeth,such as ac geared motor find relaxation phenomenon,should be after processing,can put into operation.Transfer or have a doubt on core insulation,shall be for the iron loss test.5.In the process of manufacture,transportation,installation and maintenance,should pay attention to www.facebook.com/dongfeng.motor prevent welding slag and metal scraps small foreign bodies fall into the stator core ventilation slot.
