Paano magpili sa mga parameter sa three-phase distribution transformer？

Pangunang Mga Parameter sa Transformer

Rated Capacity:

• Definition: Ang rated capacity sa transformer kay ang apparent power nga makapadala sa rated operating conditions. Ang unit kay kilovolt-amperes (kVA) o megavolt-amperes (MVA).

• Common Values: Para sa common 6.6 kV three-phase distribution transformer, ang rated capacities include 100 kVA, 200 kVA, 315 kVA, 400 kVA, 500 kVA, 630 kVA, etc.

Rated Voltage:

• Definition: Rated voltage includes the rated voltage on the high-voltage side and the rated voltage on the low-voltage side.

• Example: For a 6.6 kV transformer, 6.6 kV is the rated voltage on the high-voltage side. The rated voltage on the low-voltage side is typically 0.4 kV or 0.69 kV, depending on the user's requirements.

Short-Circuit Impedance:

• Definition: Short-circuit impedance is an important parameter of a transformer, indicating the impedance of the transformer under short-circuit conditions. The size of the short-circuit impedance affects the short-circuit current and the voltage drop during a short circuit, which is significant for the protection and operational stability of the transformer.

No-Load Loss：

• Definition: No-load loss is the power consumed by the transformer when it is in a no-load state (i.e., the secondary side is open). It primarily includes hysteresis losses and eddy current losses in the core, as well as resistance losses in the windings. The smaller the no-load loss, the higher the efficiency of the transformer.

Load Loss：

• Definition: Load loss is the power consumed by the transformer when it is in a loaded state (i.e., the secondary side is connected to a load). It primarily includes resistance losses in the windings and additional losses due to leakage flux. Load loss is proportional to the square of the load current and is an important indicator of transformer performance.

• This translation provides a clear and concise explanation of the main parameters of a transformer, including rated capacity, rated voltage, short-circuit impedance, no-load loss, and load loss.
