Method for evaluating the mechanical performances of a switchgear apparatus and switchgear apparatus for implementation of said method |
摘要 |
The method involves measuring a rotation angle of a pole shaft (20) during closing travel of electric contacts (12, 14). Two specific values are reconstituted from measurements. The specific values are compared with a specific initial operating reference of a switchgear device (10). Mechanical wear performances of a drive mechanism (22) are diagnosed based on a comparative state between the specific values obtained and specific values of the operating reference. A latching state of a toggle device (26) of the drive mechanism of the pole shaft is diagnosed according to an angular difference. An independent claim is also included for a switchgear apparatus. |
