The invention discloses an energy consumption tracking type energy-saving power transformation device. The energy consumption tracking type energy-saving power transformation device comprises a transformer body, a current detecting unit, a voltage detecting unit and an electric power detecting unit, wherein the current detecting unit, the voltage detecting unit and the electric power detecting unit are respectively arranged at the input end of a transformer body primary winding and the output end of a secondary winding. The primary winding and the secondary winding of the transformer body are of multi-tap structures in groups, every group of taps of the primary winding and the secondary winding are electrically connected with one corresponding group of output wiring terminals of an on-load tap switch, an electric actuating mechanism of the on-load tap switch is in transmission connection with a regulating switch, the control input end of the electric actuating mechanism is electrically connected with the control output end of a programmable controller, and the sample signal input end of the programmable controller is respectively electrically connected with the output end of the current detecting unit, the output end of the voltage detecting unit and the output end of the electric power detecting unit. The energy consumption tracking type energy-saving power transformation device has the advantages that when a power supply load is small, a transformer has a small rated capacity; when the power supply load is large, the transformer has a large rated capacity, and accordingly the goal of reducing no-load loss and load loss of the transformer is achieved.
Description
technical field [0001] The invention relates to a power transformation device, in particular to an energy-consumption tracking type energy-saving power transformation device. technical background [0002] With the development of society and economy, human beings' demand for electricity is increasing, and the capacity of the power system is also increasing. Therefore, the problem of saving electricity is particularly prominent. The analysis of industrial and civil power consumption shows that the power load of industrial power consumption is relatively stable and the power consumption is also relatively stable in the production arrangement of three shifts of 24-hour continuous production workshops. In the production arrangement of industrial power consumption, there are two shifts or workshops that only produce electricity during the day, the power load has large changes, and the power consumption is large during the day and small at night; the power consumption of residents ...
