摘要
近年来我国继电保护装置水平不断发展,开发了许多主设备的新型保护功能,如发电机误上电和启停机保护、厂用电切换装置、轴电流保护和大电机差动保护等,但这些保护存在一些不足,功能过于复杂,建议整合和简化。
In recent years, the level of relay protection equipment in our country is continuously rising, and many new types of protective functions for the main equipment have been developed, such as protection for generator faulty energization, protection for startup and shutdown, switch change, shaft current protection and large motor differential protection, etc. However, these protections may still appear to be insufficient and complicated in functioning. Renovation and simplification are recommended.
