Abstract

The invention discloses an intelligent transformer which comprises a transformer body and a monitoring terminal. A voltage regulating switch, a capacitance regulating switch and a load control switch are arranged in the transformer body, the capacitance regulating switch is connected with a capacitance regulating controller through a circuit, and the monitoring terminal is connected with the voltage regulating switch, the capacitance regulating switch, the load control switch and a wireless communication module through circuits. The intelligent transformer realizes remote controllability and automatic capacitance and voltage regulation, reactive compensation distribution reasonability is achieved on the whole network of an electric power system, optimized reactive flowing is achieved, and therefore power distribution energy consumption is lowered.

Description

[0001] technical field [0002] The invention relates to an intelligent transformer. [0003] Background technique [0004] The loss of transformers in rural power distribution equipment is quite serious, and the seasonal power load is strong, resulting in unnecessary waste of a large amount of power resources. According to the latest statistics, the total power loss of transformers in the whole country is more than 300 billion kWh, which is equivalent to the sum of the power consumption of three medium power consumption provinces. 50% of system loss. With the increasing tension of energy and the rapid growth of power demand, maximizing the energy saving of distribution transformers has become the most important and urgent task. [0005] SUMMARY OF THE INVENTION [0006] In order to solve the above problems, the purpose of the present invention is to provide an intelligent transformer, which realizes remote controllability, automatic capacity regulation and voltage reg...
