摘　　要：为了充分利用有限的土地资源和控制工程造价,根据户外敞开式配电装置型式布置的灵活性和多样性,建立了一种紧凑"爪"型扩大内桥屋外配电装置型式。通过改变2#主变进线的跨线方向,压缩内桥1和内桥2间隔隔离开关之间的距离,将110 kV扩大内桥配电装置纵向尺寸缩减至18m,较通用设计110-C-10方案减少了14m,节省占地面积45%。With the development of social economy, urban and suburban land is decreasing, and land resources are increasingly scarce. To make full use of limited land resources and control the project cost, according to the flexibility and diversity of outdoor switchgear, a compact＂claw＂layout scheme of expanded inter-bridge is established. By changing the overline direction of the No.2main transformer and reduce the distance of interval between the inter-bridge1 and inter-bridge2, the longitudinal size of expanded inter-bridge switchgear is reduced to 18 m, compared with the 110-C-10 universal scheme of state grid corporation, the compact layout scheme reduced the 14 m, it saved the area of 303 square meters（equivalent to 45% area）. It fully embodies the＂two type and three new＂design concept of smart substation, and the social benefit and economic benefit is remarkable.
