一、开闭所的作用 开闭所的主要作用是提高供电的可靠性和缩小事故及停电范围。开闭所有多种类型,有缩小事故和停电范围用的开闭所、增加馈电线用的开闭所和提高供电可靠性用的开闭所。如缩小事故和停电范围用的开闭所,它主要采用在自耦变压器供电方式区段。自耦变压器供电方式的供电臂长度一般在40公里左右,比一般直接供电方式的供电臂大约长1倍。当发生故障
First, the role of opening and closing The main role of opening and closing is to improve the reliability of power supply and reduce accidents and power outages. Opening and closing of all types, opening and closing stations for reducing accidents and outages, opening and closing of feeders, and opening and closing facilities for improving the reliability of power supply. Such as narrowing the scope of accidents and blackouts with the opening and closing, it is mainly used in the autotransformer power supply section. Autotransformer power supply arm length is generally about 40 km, than the general direct power supply arm about 1 times longer. When something goes wrong
