摘　　要：在整流机组进线原保护配置的基础上,提出增设反时限过负荷保护的优化方案,对反时限过负荷保护进行整定,得出不同反时限特性曲线的下限整定值,提出合理化建议,并通过不同的电流值举例验证整定曲线的合理性。On the basis of the original protection configuration of the incoming line of the rectifier set,an optimized scheme for supplementing of reverse time overload protection is put forward.It is able to perform the setting of inverse time overload protection,obtain the lower limit values under different inverse time characteristic curves,put forward rational proposals,give examples and verify the rationality of the setting curves through different current values.
