目前,各地正在开展大规模的、全面的农网改造工程.笔者结合规程要求和工作实践,浅谈农网改造中应注意的几个技术问题,供同行参考.1 合理规划,制订改造方案以往农网负荷密度小,供电半径偏大,导线截面较细,卡脖子线路、迂回供电线路普遍存在.这样末端电压在高峰时一般较低,极易造成电冰箱、空调器、洗衣机等家用电器因电流过大而烧毁,电视机等音像设备,常因电压过低而不能正常使用.
At present, all over the country are carrying out large-scale, comprehensive rural network reconstruction project. The author combined with the rules and requirements and work practices, talked about several problems in the rural power network reform should pay attention to peers for reference.1 rational planning, development and reform programs in the past Rural network load density is small, the power supply radius is too large, thin wire cross-section, neck card circuit, detour power supply line ubiquitous, so the terminal voltage is generally low at the peak, easily lead to refrigerators, air conditioners, washing machines and other household appliances due Current is too large and burned, audio-visual equipment such as television sets, often due to voltage is too low and can not be used normally.
