运变电站金属铠装柜中的二次安全防护装置设计

Design of Secondary Safety Protection Device in Metal Armored Cabinet of Substation

阐述金属铠装柜的基础构造和现场工作实际情况,变电站运行金属铠装柜中的二次安全防护装置的设计方案,并实现该装置的有效运用,探讨将活门挡板隔离车推入开关室,通过绝缘挡板将上下静触头与工作地点有效隔离,规避了安全风险,提出实践优化的建议。

This paper describes the basic structure of the metal clad cabinet and the actual situation of on-site work,the design scheme of the secondary safety protection device in the metal clad cabinet in substation operation,and the effective application of this device.It discusses the introduction of a valve damper isolation vehicle into the switch room,and the effective isolation of the upper and lower static contacts from the work site through the insulation damper,avoiding safety risks.Suggestions for practical optimization are proposed.
