Abstract

For reducing material consumption in the production of molding nozzle and improving the machining quality of the nozzle

the stress distribution of arc interruption nozzle for high voltage switchgear in the molding period is simulated by using MSC.MARC of finite element analysis software. The design and manufacture of mold for new profile-shaped nozzle is completed in combination of numerical simulation. The developed special-shaped mold of nozzle can save more than 20% of raw materials.Meanwhile

the nozzle hasuniform density distribution

excellent mechanicalproperties and electric strength.
