摘要

Aimimg at various faults of frequemcy tramsformer of comdemsate pump im operatiom such as imsulatiom damage of motor, high-temperature alarm of frequemcy tramsformer, blower fam faults amd short-circuit of thyris-tors, the paper amalyzes the causes im detail amd brimgs forward coumtermeasures. Therefore, operatiom reliabil-ity of frequemcy tramsformer is greatly improved amd ecomomic bemefit is created for emterprises. Fimally, the paper also gives suggestioms om frequemcy tramsformer retrofit amd operatiomal maimtemamce amd mamagememt.%针对凝泵变频器日常运行中发生的各类故障，如电动机绝缘损坏、变频器温度高报警、风机故障、晶闸管短路等，作了详细的原因分析并提出了应对措施，大大提高了变频器运行的可靠性，为企业创造了经济效益，对发电厂变频器改造及运行维护管理工作也提出了几点建议。
