Application of Numerical Simulation in Al-alloy Castings in High Voltage Switch
The permanent mold low pressure casting process for CT aluminum alloy shell used in high voltage switch current transformer was analyzed and calculated. The casting process of single and double lift fluid pipe was analyzed and compared, the best process was determined. The AnyCasting simulation software was used and the parameters such as material and boundary conditions were fully considered. The position and size of casting defects were determined by simulation and calculation. In practical production, the qualified castings were produced by taking corresponding measures to prevent castings from defects.
