Problems solved by technology

But there is a problem that the user voltage near the voltage regulating transformer is too high, which threatens the safe operation of electrical appliances
At the same time, the voltage quality of end users is still difficult to fully meet, and there are obvious limitations
and expensive
3. It is necessary to replace the original high-loss transformer with a low-loss transformer
But there is a problem that the amount of replacement is large and the cost is high

Abstract

The invention provides a village supercharger, comprising a transformer device, an automatic control device and a selector switch device, wherein the automatic control device is connected to the selector switch device; the transformer device is connected to the selector switch device. The invention provides a village supercharger which uses a transformer for regulating voltage stepped at a low voltage side, and the fixed voltage mode is transformed into multilevel on-load voltage regulation mode; the structure is simple and the cost is reduced greatly.

Description

technical field [0001] The invention relates to a village mouth supercharger. Background technique [0002] At present, with the development of the national economy, the national policy is expanding domestic demand, the number of small and medium-sized enterprises is increasing, and the rural market is vigorously developing. During the operation of the power supply network of relatively large industrial and mining enterprises, due to the characteristics of long power supply distance and large load changes, the line voltage loss is serious, especially in the case of low voltage and large voltage fluctuations at the power supply end such as the village entrance. It makes it difficult for industrial and mining enterprise electrical appliances, rural agricultural electrical appliances, and rural household electrical appliances to be used normally. my country has a vast territory, and it is difficult for the power supply network to fully and effectively cover all rural villages....
