Specifications of transformer capacity, 3 minutes awsome fully understood

A transformer is a device used to change AC voltage and is commonly used in power transmission, distribution and various electrical equipment. Transformer capacity refers to the maximum power that the transformer can transmit. Depending on the size of the capacity, transformers can be divided into different specifications and models. The specifications of transformer capacity and the conversion relationship between capacity and power will be introduced in detail below.

Specifications of transformer capacity

According to International Electrotechnical Commission (IEC) standards, transformer capacity specifications are measured in kilovolt-amperes (kVA). The assembly of the transformer process requires meticulous attention to detail and precision engineering. Common transformer capacity specifications include the following:

Small capacity transformer: usually refers to a transformer with a capacity of less than 1 kVA, which is commonly used in homes, small commercial buildings and some special equipment.

Medium capacity transformer: usually refers to a transformer with a capacity between 1 kVA and 500 kVA. It is commonly used in general commercial buildings, medium-sized industrial equipment and some small and medium-sized substations.

Large-capacity transformer: usually refers to a transformer with a capacity of more than 500 kVA, which is commonly used in large-scale industrial equipment, substations and large commercial buildings.

In addition, according to different application requirements, transformers can also be classified according to horizontal specifications and vertical specifications. The horizontal gauge refers to the length and width of the transformer, and the vertical gauge refers to the height of the transformer. Common transformer specifications include single-phase transformers, three-phase transformers, iron core type, fireproof type, plastic-coated type, etc.

Conversion of transformer capacity and power

Definition of capacity and power

The capacity of the transformer refers to the maximum load power that the transformer can carry, usually based on the heating power. Power refers to the energy converted or transmitted per unit time, which can be expressed as load power or rated power.

Conversion of capacity and power

There is a certain conversion relationship between capacity and power. The conversion formula is as follows:

Power (kW) = Capacity (kVA) × Power factor

Among them, power factor refers to the ratio of actual power and apparent power, and is usually used to indicate the degree of pure resistance of the load. Under ideal conditions, the power factor is 1 and the actual power is equal to the apparent power.

For example, if a transformer has a capacity of 100 kVA and a power factor of 0.8, the total power of the transformer is 100 kVA × 0.8 = 80 kW.

Ongoing transformer oil treatment maintenance is essential for reliable and resilient power grid operation.

The relationship between capacity and load

Capacity mainly depends on the design and manufacture of the transformer, while load refers to the power required in actual use. The capacity of the transformer should be selected according to the load to ensure the normal operation and life of the transformer. Generally, the capacity of the transformer should be slightly larger than the actual load capacity to ensure the stability and reliability of the transformer during operation.

At the same time, the capacity of the transformer is also affected by other factors, such as the loss, temperature rise and current density of the transformer. Therefore, when selecting the transformer capacity, we must not only consider the actual load needs, but also comprehensively consider the above factors to ensure the normal operation and service life of the transformer. Following the latest advancements, the transformer overhaul promises enhanced model performance.

In short, transformer capacity refers to the maximum power that the transformer can transmit. According to the size of the capacity, it can be divided into small capacity, medium capacity and large capacity transformers. There is a certain conversion relationship between capacity and power, which can be converted through power factor. When selecting the transformer capacity, factors such as the loss, temperature rise and current density of the transformer should be comprehensively considered based on the actual load needs to ensure the normal operation and life of the transformer.
