Closing
Description
When an electrical or manual closing order is given, the energy accumulated
in the closing spring (15) -- situated inside the operating device -- is released.
This energy is transmitted directly to the pole operating shaft (16), to ensure
closing.
The release of the energy stored up in the closing spring (15) causes displace-
ment of the moving parts -- and so the closing of the interrupting chamber --
and also reloads the opening spring (7).
