    FRACTURE ANALYSIS OF SF6 BREAKER SWITCHING BRACKET

    • SF6 breaker was fractured during short period operation by means of maro-micero fracture analysis,hardness testing,stress analysis and process analysis, the problem was solved which caused by three factors: abnormal heat-treatment,abnormal microstructure and large impact loading.
