Realize that the user end automatically keeps the output voltage stable.

Description

technical field [0001] The invention relates to the technical field of low-voltage power supply, in particular to a low-voltage intelligent voltage regulation and stabilization system. Background technique [0002] In the field of rural distribution network power supply technology, there are often low voltages at the end of the line in the station area. Usually, the voltage at the end of the line is lower than the qualified voltage of 198V. Dead angle", what measures to take to solve the current low voltage problem is imminent. [0003] At present, there are some low-voltage boosting devices for low-voltage control and improvement of power supply quality, but there are still deficiencies in actual operation. Compared with some existing low-voltage lifting devices, a low-voltage intelligent voltage regulation and stabilization system of the present invention has certain technical advantages, as follows: [0004] The present invention is compared with patent CN103606927A: ...
