摘　　要：农村电网负荷在多期农网改造的实施当中,出现了负荷随用电时间、季节产生变化的问题。解决此问题有助于实现变压器高效稳定安全运行,并控制费用和节约电能。故逐步对有载调容变压器进行推广普及,这对农网改造的进程是积极的。变压器作为配电网中的控制设备之一,其作用是分配电能,改变通过变压器的电流和电压。有载调容变压器可在有电负载运转同时调整电负载容量,令变压器的工况范围始终处于高效的范围,对电力稳定高效供应是良好的设备保障。本文针对已有的调容变压器进行了二次设计,对其原理与调容方法进行了研究,完成了可自动调容式特种变压器的设计。这对于农村电网改造中的设备选取具有一定的理论意义和现实意义。During the implementation of the multi-period rural power grid transformation in rural power grids,the problem arises that the load varies with the time and season of power consumption.Solving this problem will help achieve efficient,stable and safe operation of the transformer,and control costs and save energy.Therefore,the on-load capacityadjusting transformer is gradually promoted and popularized,and the process of rural power grid transformation is active.As one of the control devices in the power distribution network,the transformer is used to distribute electrical energy and change the current and voltage through the transformer.The on-load capacity-adjusting transformer can adjust the electric load capacity while the electric load is running,so that the working condition range of the transformer is always in the highefficiency range,which is a good equipment guarantee for stable and efficient power supply.This paper has carried out the secondary design of the existing capacity-adjusting transformer,studied its principle and capacity-adjusting method,and completed the design of the automatic capacity-adjustable special transformer in order to provide a certain theory for the equipment selection in the rural power grid transformation Meaning and practical significance.
