Abstract：Repulsion mechanism is widely used in medium voltage DC system because of its rapidity. In order to solve the key problems such as low driving speed and low efficiency in long-stroke operation, a series hybrid repulsion mechanism (SHRM) for long-stroke based on series-connected wire disc and solenoid plates is proposed by the comparative analysis of the wire disc and solenoid mechanisms. This paper also analyzes the motion characteristics of series hybrid mechanism, wire disc mechanism and solenoid mechanisms, and studies the transient magnetic field distribution of SHRM and the influence law between mechanisms. Then, a new hybrid repulsion mechanism (NHRM) is designed by optimizing the structure of the SHRM, and its motion characteristics are compared and analyzed. The results show that the NHRM combines the advantages of rapidity and persistence of two traditional mechanisms. It has fast response speed and is suitable for long-stroke fast drive. When the capacitor parameters are 1 000V/5 000μF, the response time is 0.5ms and the full travel time of 60mm is 5.6ms. This paper provides a reference for the development of long-stroke and fast repulsion mechanism of high voltage circuit breaker.
