ABSTRACT
Generally, the pipeline is longer, movable effect of the hydraulic shock waves is more obvious, the impact on the system is greater. According to the actual situation of the hydraulic system of UHV breaker, from the outlet of accumulator to pipe of main control valve is longest, and through three corners 90°. So it is the pipe which generate hydraulic shock effect of the most obvious, the paper study the dynamic characteristics of pipeline, according to simulate the hydraulic system of the opening and closing conditions.
