摘要
针对目前应用中的微机型备自投装置存在的问题,通过分析电网中各种主接线特点,提出了联络断路器有无判断及外部保护闭锁量正确使用的处理方法,并以此设计了电源与联络断路器两套自适应式备投逻辑,有效解决了以往备自投装置在应用中遇到的各种问题,并介绍了新型备自投装置的使用注意事项。
Aiming at the problem of backup power switchover unit currently used,the method of judging exist of interconnecting breaker and properly using the external protection closedown is put forward by analyzing the characteristics of the main buses in the grid.Two action logic of power switchover unit are designed,which are devided into power breaker and interconnecting breaker.The new logic resolves all kinds of problems of previous unit in use. In the end,the user’s notice of new backup power switchover unit is also introduced.
