Hybrid RMU is a kind of power circuit breaker and protects electric devices from over-current. In this paper we built a dynamic model of RMU driving mechanism using ADAMS and performed a optimal design of several design parameters. Finally we developed a prototype of RMU driving mechanism through results of analysis and confirmed it to satisfy design requisitions.

The RMU is a power apparatus which is used in loop network distribution system. This paper considers the development of the hybrid interrupter in RMU which adopts both rotating arc and thermal expansion technology. Because of the operating principle of this device, it has some merit, compared with other interrupter. In this research, the geometric construction of the interrupting techniques are given and experimental results of hybrid interrupter which is developed by new technology is introduced.
