Problems solved by technology

[0002] The power supply radius of the 10KV feeder in the rural distribution network often exceeds the national standard of 15KM, and the voltage in the second half of the feeder is often lower than the standard value of 10KV, sometimes as low as 7000V-8000V, which seriously affects the electricity consumption of large users in the second half of the feeder. Substations in sub-regions will directly affect the power consumption of all single-phase users and three-phase users on the secondary side of the transformer. If it is a dedicated substation, it will affect the daily normal operation of the enterprise
[0003] In addition, there are many small hydropower stations in the south, and the on-grid voltage varies with the seasons. The on-grid voltage is too high during the wet season, which poses a threat to the power consumption of each user on the feeder line, and may burn out transformers and equipment.
The on-grid voltage is low in the dry season, which affects the normal power consumption of users on the feeder
What's more, the voltage at the front end of the feeder is relatively high, and the voltage at the back end is low, causing serious troubles to the power supply management of power supply companies

Abstract

The invention discloses a novel adaptive medium-voltage adjusting and transforming system which comprises a three-phase autotransformer and a three-phase loaded tap switch. The system is structurally characterized in that the three-phase autotransformer is connected with the three-phase loaded tap switch which is connected with an intelligent voltage-adjusting controller through a control cable, and a power source in the three-phase autotransformer is connected with the intelligent voltage-adjusting controller. The novel adaptive medium-voltage adjusting and transforming system can guarantee qualified power supply voltage of users and reduce line loss of lines. When the intelligent voltage-adjusting controller adopts a core controller and an intelligent power manager, outputting of secondary side voltage of the autotransformer can be stabilized at 10KV by automatically controlling and adjusting tap positions of the loaded voltage-adjusting tap switch through automatic tracking of line voltage changes.

Description

technical field [0001] The invention relates to a transformer system, in particular to a novel self-adaptive medium-voltage voltage regulation and transformation system. Background technique [0002] The power supply radius of the 10KV feeder in the rural distribution network often exceeds the national standard of 15KM, and the voltage in the second half of the feeder is often lower than the standard value of 10KV, sometimes as low as 7000V to 8000V, which seriously affects the power consumption of large users in the second half of the feeder. Substations in sub-regions will directly affect the power consumption of all single-phase users and three-phase users on the secondary side of the transformer. If the substation is dedicated, it will affect the daily normal operation of the enterprise. [0003] In addition, there are many small hydropower stations in the south, and the on-grid voltage varies with the seasons. During the wet season, the on-grid voltage is too high, posi...
