The client manufactures the widest range of Medium to Ultra High Voltage (UHV) switchgear products to meet the requirements of power generation and distribution
substations in utilities and industries. products are in service for several years in many countries. We also export Low Voltage Panel Products from India based
export house. The product is highly reliable & rugged - suitable for altitude up to 2000m without any deration.
The switch systems were operated with ratchet and pawl mechanism which were expected to last for at least 50000 cycles of switching on-off. During testing, the ratchet
pawl mechanism was failing before expected life and the cause was unknown. Pawl mechanism had fillet which was having high stress concentration. Profile of pawl
mechanism was modified suitably to bring down stress concentration. Suitable program was developed for designing ratchet pawl mechanism. Also, FEA analysis carried
out later.
