【Summary Description】The issue of transformer capacity selection has recently been a hot topic among electrical designers. In today's engineering design and practice, the selection of transformer installed capacity has always been a focal point of discussion in the industry. Determining whether the transformer capacity is too large during the electrical design of a building has become an important issue in evaluating energy-saving designs in building electrical systems.
Regarding the issue of transformer capacity selection, there has been a lot of heated discussion among electrical designers recently. In today's engineering design and practice, the selection of transformer installed capacity has always been a hot topic in the industry. How to determine whether the transformer capacity is too large during building electrical design has become an important issue in evaluating energy-saving design in building electrical systems. In recent years, with the continuous development of society, China's construction industry has also been developing rapidly. To meet the development needs of the new era, the transformer capacity indicators in building electrical design have become very important. The capacity indicators of transformers can be used to evaluate whether the building electrical design meets the required standards and requirements. In this article, we will analyze the considerations that need to be taken into account when selecting transformer capacity, hoping to provide some help to electrical designers.
[1] Problem description:
A substation can usually consist of two transformers forming a power supply unit. Do the capacities of the two transformers have to be the same? If the capacities of the two transformers are different, what considerations should be taken into account?
[2] Cause analysis:
The capacities of the two transformers can be different, but it is not recommended to choose this way during design.
Existing issue: Poor interchangeability during daily operation. When the larger capacity transformer is out of service, the smaller capacity transformer may not be able to meet the power supply load requirements.
[3] Countermeasures:
1. The capacity difference between the two transformers should not be too large.
2. When one transformer is out of service, the capacity of the smaller transformer should meet the power supply requirements for all primary and secondary loads to satisfy emergency requirements during transformer switching operation.
