초록

Generally the high-voltage and high-current making switch is used to test the short-circuit test. The making switch should be operated always same speed/time and kept electrical-mechanical characteristic. There are spring charge type, hydro-pneumatic type and compressed air type etc. according to operation method of making switch contacts. Especially the making switch contacts of hydro-pneumatic type are moved by actuator and accumulator. To keep same speed/time of contacts and characteristic of making switch, actuator and accumulator should be worked always uniformly. So the dynamic analysis of actuator and accumulator of hydro-pneumatic type making switch will be helpful to maintain and design.
