2. Dry-type transformer parameter table

Since there are many models of dry-type transformers, and the parameters of each model may vary due to different designs, manufacturing and use environments, it is impossible to provide a universal parameter table. However, the following are some common dry-type transformer parameters and their meanings:

Rated capacity: The apparent power (KVA or MVA) that the transformer can output under rated conditions.
Rated voltage: The rated voltage (KV) of the primary and secondary sides of the transformer.
Rated current: The current (A) that the transformer can output under rated conditions.
Short-circuit impedance: Indicates the impedance in the winding when the transformer is short-circuited (%).
Connection group number: Indicates the connection method of the transformer winding, such as Dyn11, etc.
Rated frequency: The rated operating frequency (Hz) designed for the transformer, usually 50Hz or 60Hz.
Insulation heat resistance grade: Indicates the heat resistance grade of the transformer winding and insulation material, such as A, E, B, F, H, etc.
Loss: Including no-load loss and load loss, indicating the energy loss of the transformer under no-load and load conditions (W).
Efficiency: Indicates the efficiency of the transformer in the energy conversion process (%).

Please note that the above parameters are only examples, and not all dry-type transformers include these parameters. In actual applications, the parameters of the transformer should be determined according to the specific model and the technical data provided by the manufacturer.

In addition, for a specific model of dry-type transformer, it is recommended to consult the technical manual provided by the manufacturer or contact the manufacturer for detailed parameter information and technical support.
