“套屏改造”在继电保护改造工程中的应用

The Application of"Panel Cabinet Covering Reconstruction"in Relay Protection Reconstruction Project

针对传统的保护装置更换方法作业强度大、范围广,需要申请较长的停电时间的现状,提出在改造过程中采用“套屏改造”的方法,只对保护装置进行更换。阐述了改造流程和安全管控措施,实践证明“套屏改造”难度减小,用时短,效果良好。

In view of the current situation that the traditional replacement method of protection device has a large working intensity and a wide range,and needs to apply for a long time power cutoff,it is proposed to adopt the method of"panel cabinet covering reconstruction"in the process of upgrading,and only replace the protection device.The upgrading process and safety control measures are described.The practice shows that the"panel cabinet covering reconstruction"is of difficulty reduced,the time spent shortened and good effectiveness.
