Abstract EN
Transmission mechanism is one of the most important parts of the Ultra-High Voltage (UHV) circuit breaker.
It has specific characteristics such as fast response, high speed, and heavy load in the processes of open and close actions.
This paper studies the effects of multiple clearances on the working characteristics of transmission mechanism system, especially the motion of its journal center path during operation.
It builds a nonlinear kinetic model of transmission mechanism considering the system energy losses due to the impact and friction between the journal and bearing inside clearance joints.
Also, an experimental platform is built to measure the displacement and velocity of the moving contact.
The results show that the existence of 15 clearance joints in our mechanism system can cause hysteresis effects on the velocity and acceleration of the moving contact, as well as its acceleration fluctuation.
Meanwhile, the increase of friction coefficient will stabilize the dynamic characteristic.
In addition, both the experimental and simulation results indicate that the motion of the journal center, which is unevenly distributed along the circle, is characterized by three phases: free flight motion, contact motion, and impact motion.
