| 摘要 |
The invention concerns a spring arrangement (10) for operating a high and medium voltage circuit breaker comprising
- a cylindrical housing (14) having a main axis (A),
- an actuation rod (18),
- a coil spring (12) arranged in the cylindrical housing (14), coupled with the rod (18), and
- a coupling arrangement (20) coupling an end (12b) of the spring (12) with an end (18b) of the rod (18),
wherein the coupling arrangement (20) comprises an articulation for guiding an end (18b) of the rod (18) in rotation with respect to the second end (12b) of the spring (12) around a second axis (B) perpendicular to said main axis (A) and comprises sliding means for the translational guiding of the second end (18b) of the rod (18) along said main axis (A). |
