摘　　要：日照钢铁有限公司1580带钢生产线上选用的三裂解整流变压器频发故障,本文分析了变压器的故障原因,通过提高变压器阻抗值,并对变压器引线夹持和器身压板做了相应的改进,提高了变压器抗短路能力,延长了使用寿命。Because accidents often occur in the three-cracking rectifier transformer mounted on 1580 strip produetio,1 line ill Rizhao Steel Co. , Ltd. , the reason of the phenomenon is analyzed. The result indicates that the aecidenls can be reduced by increasing the resistance value of the transformer, modifying the active part pressing plate and adding a clampng part for the transformer lead. In this way, the ability of the cracking rectifier transfiwmer for wilhstanding the short circuit can be improved and its service life can be prolonged.
