Part Ⅱ: Product Features

1. Low Loss

① The transposition between parallel conductors is optimized to make the cross-link flux uniform and reduce the circulating current loss caused by magnetic flux leakage.

② Slotting process is implemented on the core small stage piece to reduce the loss of structural parts of the core and prevent local overheating.

2. High Resistance to Short Circuit

① Hydraulic transposition tools are used for conductor transposition.

② The body adopts constant pressure drying and overall assembly, and the overall assembly adopts hot set.

3. Low Noise

The iron core is "soft connected" with the oil tank as a whole to reduce the transmission of noise from the body to the oil tank.

4. Low Temperature Rise

Control of transverse eddy current losses in windings.

5. Low partial discharge, extend Transformer Service life.

Analytical calculation of the electric field and improvement of the area where the electric field is concentrated.

6. Potential distribution is effectively improved by application of software to calulate the impact potential distribution and gradient potential distribution, calculate the potential distribution between the various parts of the coil, between the coil and the coil, coil and earthing.

7. High Earthquake Resistance

The casing design uses the dynamic design method, the horizontal acceleration is taken as 0.5g, the waveform is taken as resonant sinusoidal third harmonic, and the loading part is the lower end of the casing flange seat. The transformer body adopts the static design method, and the static horizontal acceleration is 0.5g.

8. Transformers Have Good Mechanical Strength

Eliminate the weak point of structural member strength and improve the mechanical strength of structural members through software simulation calculation.
