一、外线工程平面图 施工总平面图内绘出外线工程图,包含的主要内容有高压架空线路或电缆线路敷设方位;变电所的位置、数量、容量和形式;低压架空线路的电杆形式、编号、导线的型号截面及各回路导线的根数等。如图1所示。 图中有三栋新建工程是望月楼、履安饭店和康复游乐中心。高压线用铝绞线LJ—3×16,变压器采用户外杆上安装方式,S_7-315/10表示三相油浸自冷式铜绕组电力变压器,额定容量315kVA,高压10kV。 配电线路主要是用绝缘线和裸线两类,在市区或居民区尽量用绝缘线,以策安全。绝缘线按材质
First, the outer-line project plan construction outline drawing of the outer line drawing, including the main content of the high-voltage overhead lines or cable line laying orientation; substation location, quantity, capacity and form; low-voltage overhead line pole form, number , wire model cross section and the number of loop conductors. As shown in Figure 1. There are three new construction projects in the picture: Momoyuki Building, Luan Hotel and Rehabilitation Amusement Center. The aluminum wire of the high voltage line is LJ—3×16. The transformer is installed on the outdoor pole. S_7-315/10 is the three-phase oil-immersed self-cooling copper winding power transformer with the rated capacity of 315kVA and the high voltage of 10kV. The distribution line is mainly composed of two types of insulated wire and bare wire. Use insulated wire in urban areas or residential areas as much as possible to ensure safety. Insulated wire according to material
