摘要
本文根据AP1000机组主泵电机过载保护定值的计算结果和校验方式,详细阐述了SEL-710型综合保护继电器过载保护定值计算方法,分析了现行的主泵电机过载保护定值及其校验方式存在的缺陷与不足,提出了新的过载保护定值及校验方式,并通过试验验证了新的保护校验方式合理可行,为完善AP1000主泵电机及其他电机负荷的过载保护计算及校验提供了建议和参考。
According to calculation result and verifying test for AP1000 RCP overload protection setting, this paper demonstrates the calculation way of SEL-710 relay overload protection setting, analyzes the deficiencies of the RCP overload protection settings and verifying test, provides a new overload protection setting and verifying scheme, verifies rationality and feasibility for the verifying scheme by the improved test. It provides advice and instructions for AP1000 RCP and other motors overload protection calculation and setting verifying tests.
