Distribution transformer with self-adaptation function

Abstract

The invention relates to a distribution transformer with a self-adaptation function. The distribution transformer with the self-adaptation function comprises a distribution transformer body, an accessory of the distribution transformer body, an on-load capacitance and voltage adjustment integrated switch, an on-load capacitance and voltage adjustment comprehensive control device and a loaded side current transformer, wherein the distribution transformer body and the accessory finish the operations of voltage boosting and reduction, electricity transmission and on-loaded capacitance and voltage adjustment, the capacitance and voltage adjustment integrated switch finishes switchover of switching on and off the capacitance and voltage adjustment gears, the on-load capacitance and voltage adjustment comprehensive control device monitors and judges the operation state of the distribution transformer by monitoring the current data and voltage data, obtained through a current collecting unit and a voltage collecting unit, on the loaded side of the distribution transformer in real time and finishes control cover the on-load capacitance and voltage adjustment integrated switch, and the loaded side current transformer is used for providing the current data on the loaded side of the distribution transformer.

Description

technical field [0001] The invention relates to a distribution transformer in the field of power distribution, in particular to an on-load, capacity-adjusting and voltage-regulating distribution transformer with an adaptive function. Background technique [0002] As the main power distribution equipment of the distribution network at the end of the power system, the distribution transformer has a large and rapid growth trend in demand. Distribution transformers are mainly used in rural power grids and urban distribution networks. Rural power grid loads are characterized by strong seasonality and large peak-to-valley differences in power consumption, while urban power grids have more obvious peak-to-valley differences and more frequent peak-to-valley rotations. In order to meet the electricity demand during the peak load, the transformer is configured according to the maximum load when selecting the transformer, which leads to the distribution transformer being in a light-loa...

Problems solved by technology

In addition, the technical means of load forecasting and load tracking are lacking, and the load cannot be tracked accurately, which also seriously affects the popularization and use of on-load capacity regulating distribution transformers.
