Abstract

Aiming to the calculation of bursting pressure of casting aluminum enclosure of high voltage switchgear

design principle of one-story withstand pressure vessel and calculation formula of welding cylinder are adopted.Considering the effect from casting process

bursting pressure of partial casting enclosure is calculated.In addition hydraulic test is also carried out on the enclosure to verify the calculated result.Meanwhile the calculation skeleton formula of bursting pressure of casting aluminum enclosure for high voltage switchgear is established.
