摘要
文章介绍了数字自动化控制系统中降压变压器保护的配置,强化主保护,简化近后备保护,加强低(中)压侧远后备保护。讨论了部分保护继电器,说明了开发数字保护断路器的必要性,并对断路器保护应具备的功能提出了建议。
The paper introduces the configuration of step- down transformer protection in digital automation control system. Strengthening the main protection, simplifying the nearly backup protection and reinforcing the low （in） pressure far side of backup protection. It discusses some of the protection relay, the necessity of digital protection circuit breaker, and made a number of recommendations on the function of protection circuit breaker.
