the performance of the company
after being put into operation for one year, 6 imported 200kw 6kv bcps in jiangsu jianbi power plant broke down. the insulation resistance of the stator winding is only 20mωat the most, and the winding insulating layer in stator core notch wore seriously. guide bearing pads were damaged totally, and nonmetal wear materials changed colors, cracked and shed with the heat frequently (picture 1). the guide bearing sleeve got severe abrasion (picture 2). the most serious thing is that the separated bearing bush pieces fell into the inside of the motor, which led to the rubbing of the stator and the rotor. the stator core deformed seriously and the winding was damaged (picture 3). similar problems occur quite often in the bcps of the same type.
