摘要
赣州电网对220kV金堂变电站1号主变压器、220kV潭东变电站1号主变压器实施了保护双重化改造两项技改工程,改造工程的设计需要充分了解现场的原有设备状况,并结合现场实际尽可能地完善。就设计中的实际问题包括保护组屏方式、保护配置、控制回路改造、直流电源的配置、保护交流回路设计等方面进行初步探讨和实践总结。
Reform of protection double configuration on No.1 maintransformer of 220 kV Jintang Substation and No.1 main transformer of 220 kV Tandong Substation was undertaken in 2006. Reform project required information of equipment status. Especially, problems in design were discussed： protection mode group panel mode, protection configuration, control loop reform, configuration of direct current power supply, design for alternative current loop protection.
