摘要
10kV配电间高压侧主接线和配电装置的正确选择与配电间可靠性、灵活性、经济性关系极大。论述了1台或2台变压器常用的高、低压侧的主接线,从主要电器负荷开关——熔断器组合电器入手,提出了双电源供电的3种模式,对它们进行了详细地分析比较。最后,推荐应优先采用组合电器的"双"线变组的主接线方案。
The right selection of the main wiring and equipments of high voltage side of 10 kV power distribution room is closely related to power distribution’s room reliability,flexibility and economical efficiency. The general main wiring of high and low voltage side of one or two transformers was expounded. By introducing the main electrical apparatus such as switch-fuse composite apparatus,three dual-power supply models were analyzed and compaired in detail,and the priority of using dual line-transformation group of composite apparatus for main wiring was recommended.
