This paper analyzed the process and principle of opening(closing) in an SF6 HV GCB with new type hydraulic-spring mechanism.The force characteristics of the disc spring was assumed by a certain average values
and the instantaneous opening(closing) speed were calculated.It had been proved that the calculated data meet well the practically measured results.Finally
Some feasible suggest for designing of the hydraulic-spring mechanism has been given.
