摘要
介绍了电力变压器纵联差动保护的工作原理和变压器在运行中保护装置的保护范围。对变压器在差动保护范围内发生短路后的电流分布情况和动作原理进行了比较详细地分析,差动保护装置一旦动作,将同时断开变压器的原、副边侧的断路器(开关),及时把变压器从电网上切除。
Job elements in vertical differential protect of electric transformer and protect bound in course of electric transformer are introduced. Expound differential protector current distributing and action elements in short circuit of protect bound. Acted protector of differential, switch opening, transformer excise from power supply.
