负荷开关-熔断器组合电器柜在10 kV线路及台架变保护中的应用研究

Application Research of Load Switch-Fuse Combined Electrical Apparatus in the Protection Section of 10 kV Lines and Pole Transformer

文章主要研究了城区台架变取消柱上跌落式熔断器后的替代方案,在电源接入点配电房内安装负荷开关+熔断器组合柜对台架变压器供电。从熔断器参数、保护范围及要求等几个方面论述了替代方案的可行性。

The alternative scheme of urban platform transformer after canceling the pole drop fuse is mainly studied in this paper.The load switch+fuse combination cabinet is installed in the power supply access point distribution room to supply power to the stand transformer.The feasibility of alternative schemes is discussed from several aspects such as fuse parameters,protection scope and requirements.
