摘要(Abstract)：
变电站微机五防的主要盲点是防空程措施不够全面。借鉴GIS设备采用的电编码锁带无源反校回路,防止微机五防走空程的方法,推广到常规的隔离开关操作和接地线装拆方面上,在技术上进行了可行性分析,从而弥补了微机五防在防空程方面存在不足的缺陷,使微机五防能进行全面正确的闭锁成为可能。
At present, the main blind spot of computer five-proof in transformer substation is that measures is incomprehensive to prevent unfruitful program. According to electric coder lock with passive contrary checkout circuit in GIS equipments, the method which can prevent computer five-proof from running unfruitful program is popularized to general isolator's operation and earth line's installation and backout. The method is a feasible on technique and remedy the defect of computer five-proof in terms of unfruitful program preventing, which makes it possible for a comprehensive and correct atresia.
