摘要
慢速机械开关是特高压直流输电系统可控自恢复消能装置中重要的开关设备,在装置中起到控制和保护用,其必须具备短时间快速合闸、可靠开断避雷器残余直流持续电流的能力。介绍了慢速机械开关的方案设计、核心部件设计和校核以及型式试验,最终研制成功了慢速机械开关。
The slow speed mechanical switcher is an important switching device in the controllable self-recovery energy dissipation device of the UHV DC transmission system,which plays a role in the control and protection of the device.It must have the ability to quickly switch on in a short time and reliably disconnect the residual DC continuous current of the arrester.This paper introduces the scheme design,core component design and check,and type test of the slow mechanical switch,finally,the slow mechanical switch is successfully developed.
