摘　　要：通过对型号为ＳＦＳ７－４００００／１２１的故障变压器吊心检查及现场测试，弄清了变压器油绝缘电阻降低的原因，阐明了绝缘油净化方法，从理论上探讨了导电粒子（离子和胶粒）对变压器油绝缘电阻的影响。The cause of reduction of insulating oil resistance in a fault SFS7-40000/121 transformer was known through checking its active body and measuring in the field.A cleaning treatment method of insulating oil is introduced in this paper.The influence of the carriers (ions and colloidal particles) on insulating resistance of transformer oil is discussed theoretically.
