有载自动调容配电变压器在农网线路上的应用

针对宁夏农村电网季节性和周期性负荷波动较大,配电变压器功率因数低,效率低, 电能浪费大的问题,对宁夏农村电网现状进行分析,提出更新改造方案。应用结果表明:推广使用有载调容配电变压器,使变压器在低负荷时处于小容量状态运行,可大幅降低变压器空载损耗,在农村电网有着极其显著的节能效果和社会效益。

Application of on-load regulating capacity transformer in rural power network

Aiming at the problem such as big of seasonal and periodical load fluctuate,low of thepower factor of the distribution transformer,large of power waste in the Ningxia rural powernetwork,analyzes the status quo of Ningxia rural power network,puts forward reform scheme. Theapplication result shows that the On-load regulating capacity distribution transformer can keep smallcapacity operation under the low load,and significantly reduce the no-load loss of the transformer,gain a remarkable effect of energy saving and social benefits in rural power grid.
