10kV oil-immersed transformer is an important power equipment, and its performance parameters have a key impact on the selection, operation and maintenance of transformer. The following will introduce the main parameters and related characteristics of 10kV oil-immersed transformer in detail, aiming to provide readers with a comprehensive and in-depth understanding.

First of all, we need to make it clear that the main parameters of 10kV oil-immersed transformer are numerous, including rated voltage, rated capacity, short-circuit impedance, no-load current, loss, weight, external dimensions, etc. These parameters not only reflect the electrical performance of the transformer, but also determine its operating characteristics in the power system.

The rated voltage is the voltage value that the transformer bears during normal operation, for a 10kV oil-immersed transformer, its input voltage is usually 10kV, and the output voltage is designed according to specific needs, generally 380/220V. The choice of rated voltage is crucial for the safe and stable operation of the transformer, and too high or too low voltage can cause damage to the transformer or unstable operation.

The rated capacity is the maximum power that the transformer can operate stably for a long time, and is usually expressed in kVA. Different application scenarios have different requirements for the rated capacity of transformers, so it is necessary to determine according to actual needs when selecting transformers. The reasonable selection of rated capacity is of great significance to ensure the stable operation of the power system.

Short-circuit impedance is the impedance of the transformer under short-circuit conditions, which reflects the transformer’s ability to limit the short-circuit current. The magnitude of the short-circuit impedance is related to the structure, materials and manufacturing process of the transformer, which is of great significance for protecting the power system from the damage of short-circuit current.

No-load current is the current that flows through the transformer in the no-load state, which is mainly composed of the core loss and excitation current of the transformer. The size of the no-load current can reflect the core quality and excitation performance of the transformer, which is one of the important indicators to evaluate the performance of the transformer.

Loss is the energy loss generated during the operation of the transformer, including load loss and no-load loss. Load loss is the loss incurred by the transformer when it is operating under load, while no-load loss is the loss incurred by the transformer in the no-load state. Reducing transformer losses is of great significance to improve the efficiency and economy of the power system.

In addition, the weight, dimensions and other parameters of the 10kV oil-immersed transformer are also factors that need to be considered in the selection and use process. The size of the weight and size not only affects the installation and transportation of the transformer, but also determines its layout and configuration in the power system.

In addition to the above main parameters, there are some other characteristics of 10kV oil-immersed transformers that need attention. For example, the cooling method, insulation level, temperature rise limit, etc., will affect the operational performance and safety of the transformer. Therefore, when selecting and using a 10kV oil-immersed transformer, various factors need to be considered comprehensively to ensure that it can meet the actual needs of the power system.

In general, the parameters of 10kV oil-immersed transformer are numerous and complex, and each parameter has an important impact on the performance and use of the transformer. Therefore, when selecting and using transformers, it is necessary to fully understand their parameters and characteristics, and make reasonable choices according to actual needs. At the same time, it is also necessary to pay attention to the maintenance and maintenance of the transformer to ensure its long-term stable operation and provide a strong guarantee for the safe operation of the power system.
