摘要
详细地介绍了220kV降压变后备保护的配置及定值计算原则,特别针对变压器在中、低压侧外部故障时由于热稳定不满足要求而引起变压器损坏的问题,提出了新的见解和建议。
The principle of the configurat ion and setting calculation of back-up protection for 220 kV step-down transf ormer was introduced in detail.In the light of the transformer damage due to the insufficient thermal stability under the condition of external fault of MV or L V side,the new view and suggestion were presented.
