摘要
分析目前农村配网改造工程,基于台区供电地理条件,以变压器负载率、供电线路末端电压等满足规程要求作为设计依据。分析台区电源引接、电气主接线选择,台区变压器容量选择方法、结构形式是否符合国家规程要求,高压导线、低压导线选择、布置,高雷地区防雷措施及接地网建设,最后考虑了施工造成停电所采取的措施。
In this paper,the reconstruction project of rural power grid is analyzed.Based on the geographical conditions of apower supply region,and the design is grounded in whether the load rate of the transformer and the voltage at the terminal of the supply line meet the requirements of the regulation.The power supply connection and the selection of electrical main wiring in a power supply region is also analyzed.To analyze if the selection of transformer capacity and its structure in the power supply region are in conformity with the requirements of the state regulations,and analyze lightning protection measures and the construction of grounding grids in areas vulnerable to lightning strikes.At last,consider the measures taken by the power outage caused by the construction of.The solutions to power outage caused by construction is also considered.
