摘 要：對比分析了 IEC 標準和 IEEE 標準對斷路器耐受暫態恢復電壓(TRV)的要求。基于 IEC 62271 標準關于斷路器在特定電路中耐受 TRV 的特殊要求，收集某核電廠的廠用變壓器、共箱母線等設備參數，利用 IEC 標準中的計算方法得出耐受 TRV 和恢復電壓上升速率(RRRV)的理論值(預期值)。通過斷路器的 T60 型式試驗，驗證了 VD4 斷路器滿足耐受 TRV 的要求。

Abstract: The paper makes comparative analysis of the requirements of circuit breakers tolerant transient recovery voltage (TRV) in IEC standard and IEEE standard. The authors based on the IEC 62271 special requirements of circuit breakers tolerant TRV in special circuits,collect parameters of auxiliary transformers, common enclosure buses and other equipments in a nuclear power plant, and apply the calculation method from IEC standard to get the theoretical values (expected values) of tolerant TRV and transient recovery voltage rising rate (RRRV).It is verified by T60 type test of circuit breakers that the VD4 circuit breaker meets the requirements of tolerant TRV.
Key words: IEC standard; nuclear power plant; middle-voltage circuit breaker; transient recovery voltage; T60 type test
