| 摘 要： | 变压器保护主要有瓦斯保护和纵联差动保护，纵差动是变压器必须采用的保护原理。可以反映变压器的各种内部相间和接地故障。文章提出了一种不受空投时励磁涌流影响的新方法，用阻抗继电器反应空投于内部故障．这种保护配置方式在内部故障时有很高的灵敏度，在外部故障时又有很强的制动作用，不反映空投时的励磁涌流．却能反映变压器空载合闸时有故障的情况．解决了变压器差动保护的难题。

| Abstract: | The transformer protection mainly introduces the gas protection and differs to move the protection, differing to move protection is the protection principle that the transformer must adopt, can reflect various inner part of the transformer alternate and connect a ground of breakdown, in the text not only introduced the traditional protection method, but also put forward a kind of be free from to airdrop the magnetizing inrush out to flow the influence of new method, use the resistance after the electric app... |
