Fault handling Although there are damage inspection found that bar insulation,but winding wire
itself is not affected.So we try to adopt a new method for processing,insulating layer with teflon
insulation bags,namely use insulation partition way on the electric motor cooling fan basis of the original winding wire rods to strengthen its insulation capability.Specific operation,the motor to overhaul,disintegration,and high pressure fan with bamboo knife of compressed air to motor winding and iron core of the dust cleared,the breakdown point and all loose clearance winding wire rods,with at least double (single withstand voltage 2000 v) teflon insulation tape winding,with bamboo slot wedge pressure,and then filled with resin,dry.All slot wedge update or upset,make the slot wedge,wire rods are stationary,able to withstand motor starting,running huge electric power.Processing has been completed,to direct current withstand voltage test of the motor again,when the step up to 5000 v,instrument and the "breakdown" signal,review found that motor used in 50 lead was copper core rubber line wholesalemotor.blogspot.com breakdown.Originally because motor operating environment temperature is higher,and the circulating water station in the original design,the motor selection using natural air cooling,according to the arrangement of design room,adjacent to the center line of the two motors from 3.0 m,running a motor cooling wind,is just another motor cooling air into the wind,because of the close,the motor often run in more than 40 degrees Celsius temperature environment,accelerate the rubber insulation aging,make
the rotor balancing machine shorten service life.The processing of wire insulation to strengthen on the motor.Lead to motor clean with gasoline,white cloth,and then using 6 kv with heat insulation tube heat insulation,all dc withstand voltage test was carried out on the motor after processed,the result completely conform to the requirements of the regulations.Equipment is working well so far.
