“三遥”无人值守箱式环网开关站的应用及探讨

Application and Inquiring of “Three Remote"Unmanned Box Loop Networks Switch Station

箱式环网开关站所具有的占地少、外观漂亮的优点 ,既解决了城区用地紧张的矛盾 ,又不影响市容 ,从而促进了开关站布点工作的开展。同时 ,通过“三遥”、“热倒”及保护方式的改进 ,充分发挥了箱式环网开关站的功能 。

Because of the benefits of the box loop networks'switch station in volume and appearance,the box loop networks'switch station are widely used in the urban distribution networks construction and reconstruction.At the same time,through “three remote”,“hot exchange”and “protective relaying”,the station′s function has fully been exerted and the reliability is improved.
