Two driving systems in which a circuit breaker is driven synchronously and sequentially by two devices which are connected with relatively long hydraulic pipes were investigated. Numerical analysis method of pipe flow, which is modeled by lumped parameter system, was compared with theoretical solutions modeled by using distributed parameter system. It was confirmed that proper results could be obtained by the numerical method. Hydraulic transmission and operating time of two driving system were investigated by using the numerical method and measurement. Dimensions of the connecting pipe and other hydraulic constants influence the motion time of two devices. Particularly, the different length of connecting pipe at asymmetrical arrangement has much influence. The synchronous driving system suppresses the time difference of two operating devices by symmetrical arrangement and appropriate dimensions of connection pipe. The sequential driving system which uses dashpot pressure gives us stable delay time under the change of conditions and makes it possible to adjust the range of delay time by using hydraulic volume and restrictor. |
