  1. Why does the starter break easily

    1. The generator does not operate according to the specified technical conditions, such as the stator voltage is too high and the iron loss increases; If the load current is too large, the copper loss of stator winding increases; The frequency is too low, which slows down the speed of the cooling fan and affects the heat dissipation of the generator; The power factor is too low, which increases the excitation current of the rotor and causes the rotor to heat. Check whether the indication of the monitoring instrument is normal. If it is abnormal, necessary adjustment and treatment shall be carried out to make the generator operate according to the specified technical conditions.


    2. The three-phase load current of the generator is unbalanced, and the overloaded one-phase winding will overheat; If the difference of three-phase current exceeds 10% of the rated current, it is a serious cricket phase current imbalance. The three-phase current imbalance will produce negative sequence
