Voltage regulation and transformation system

Abstract

The invention discloses a voltage regulation and transformation system. According to the invention, through a coarse and fine voltage regulation on-load voltage regulator connected with an autotransformer, the output voltage of a self-coupling transformer can be adjusted in a voltage regulation level range with a preset number of voltage regulation levels, the requirements of users on different levels of voltage can be met, the voltage regulation can be realized under the condition that the autotransformer is electrified through the coarse and fine voltage regulation on-load voltage regulator;the self-coupling transformer does not need to be powered off, the power supply stability of the self-coupling transformer is improved, so that a user does not need to arrange an additional power supply facility to guarantee the power utilization requirement, the cost is reduced, the self-coupling transformer has the advantage of lower cost compared with other types of transformers, and the costcan be further reduced.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a voltage regulation and transformation system. Background technique [0002] After the power station generates electric energy, it can be transmitted to each power consumption unit through the power grid. The power grid usually steps down the power through the transformer and then provides the power to the load of each power consumption unit, such as the equipment provided to each factory, etc. With the development of various industries, many power consumers have higher and higher requirements for the refinement of voltage level and the stability of electric energy. For example, the smelting electrolysis industry has higher requirements for the voltage level of the output voltage provided by the power grid through the transformer. On the one hand, it is required to be able to provide electric energy with adjustable voltage levels, and on the other hand, it is required that the trans...

[0002] After the power station generates electric energy, it can be transmitted to each power consumption unit through the power grid. The power grid usually steps down the power through the transformer and then provides the power to the load of each power consumption unit, such as the equipment provided to each factory, etc. With the development of various industries, many power consumers have higher and higher requirements for the refinement of voltage level and the stability of electric energy. For example, the smelting electrolysis industry has higher requirements for the voltage level of the output voltage provided by the power grid through the transformer. On the one hand, it is required to be able to provide electric energy with adjustable voltage levels, and on the other hand, it is required that the transformer can provide electric energy in a stable and continuous manner. However, there is no transformer system in the prior art that can meet this demand, and the power consumer needs to set up additional Power supply facilities guarantee electricity demand, which increases costs
