Description

Technical Field

[0001] The utility model relates to the field of transformers, in particular to a reactive power regulation transformer structure for a low-voltage power distribution network. Background Art

[0002] The working principle of the reactive power regulation transformer in the low voltage distribution network is to improve the power factor and voltage quality of the power grid by adjusting the reactive power output of the transformer;

[0003] Most of the power loads in the power grid, such as motors and transformers, are inductive loads and consume reactive power during operation. The transmission of reactive power will increase the load on the power grid, increase power grid losses, and reduce system voltage.

[0004] The reactive power regulating transformer is generally implemented by connecting a device with a capacitive power load and an inductive power load in parallel in the same circuit, and energy is exchanged between the two loads; in this way, the reactive power required by the inductive load can be compensated by the reactive power output by the capacitive load;

[0005] Through the operation of reactive power regulation transformer, the proportional constant of active power in the power grid can be increased, the design capacity of power generation and power supply equipment can be reduced, line loss can be reduced, and the stability and power quality of the power grid can be improved; at the same time, the appropriate compensation method and compensation capacity can be determined according to the load conditions and the requirements of the power supply department to achieve the best compensation effect; common reactive power compensation methods include centralized compensation, group compensation and single motor on-site compensation, etc.

[0006] In practical applications, it is necessary to select appropriate reactive power regulation equipment according to the specific grid conditions and needs, and to perform reasonable configuration and debugging to ensure its normal and effective operation and achieve the goal of reactive power compensation. In addition, the implementation of reactive power compensation also needs to comply with relevant power specifications and standards to ensure the safe and stable operation of the power grid. If it involves the operation and maintenance of specific reactive power regulation transformer equipment, it is recommended that it be carried out by professional power technicians.

[0007] When the reactive power regulating transformer is fixed on the mounting frame by screw connection, its position cannot be fine-tuned during actual operation; if there is a dimensional deviation in the mounting frame during the manufacturing or installation process, it cannot be corrected by fine-tuning, which may cause inaccurate connection between the transformer and other equipment, increase the difficulty and stress of line connection, and affect electrical performance and reliability.
