摘要
根据有些农村35kV变电站装设跌落保险的情况,分析了在跌落保险缺相运行时的故障特征,并以此提出了缺相保护构成的判据。缺相保护、过负荷保护和两段过流后备保护构成整套变压器保护。
According to the conditions of drop-fuse used in some 35 kV power substations of countryside, phaselacking fault characteristics are analyzed and a protection criterion is proposed in this paper. The transformer protection is composed of phase-lacking, over loading and two zones backup over-current protections.
