Intelligent Stepless Capacitance Adjustment Distribution Transformer

Abstract

The invention discloses an intelligent stepless capacity adjustment distribution transformer, which comprises an energy-saving distribution transformer, an on-load magnetic adjustment switch and a control box; the control box is set in a dynamic capacity adjustment controller; the dynamic capacity adjustment The controller is directly connected with the energy-saving distribution transformer to obtain the operating parameters of the energy-saving distribution transformer; the energy-saving distribution transformer includes a high-voltage coil, and the high-voltage coil has a plurality of taps. The terminal of the adjustment gear of the on-load magnetic switch is connected; the on-load magnetic switch is connected to the dynamic capacity adjustment controller, and the dynamic capacity adjustment controller realizes all the functions through the on-load magnetic adjustment switch. Describe the capacity regulation of energy-saving distribution transformers. The intelligent stepless capacity-adjusting distribution transformer of the present invention has the advantages of being able to automatically adjust the capacity according to the actual load of the distribution transformer, completely solving the problem of large horse-drawn trolleys in the distribution network, and improving the energy-saving effect.

Description

technical field [0001] The invention relates to a transformer, in particular to an intelligent stepless capacity-adjusting power distribution transformer used in a power system. Background technique [0002] The loss of the transformer occupies a very considerable proportion in the loss of the power grid, especially the large distribution network. Distribution transformers are widely used and their power loss has attracted much attention. Therefore, the loss reduction of distribution transformers is directly related to the economic benefits of power companies and society. [0003] Distribution transformers are mainly used in rural power grids and urban distribution networks. Rural power grid load has the characteristics of strong seasonality and large peak-to-valley difference in power consumption. The difference between the peak and valley of the urban power grid is more obvious, and its peak and valley rotation is more frequent. However, in order to meet the power dema...

AI Technical Summary

Problems solved by technology

This method can only be used for loads that change within seasons, and is not suitable for loads that change frequently, and the cost is high and maintenance costs are high

[0007] (2) In the past few years, no-load capacity regulating transformers have been applied in distribution networks, but due to the need for power-off regulation

[0010] From the perspective of power supply reliability, passing a large current in a small-capacity state will cause the transformer to burn out. In order to ensure the safety of power supply, the current at the capacity adjustment point has to be reduced, which will weaken the energy-saving effect.
