The determination of the kinematics parameters for operating mechanism of the circuit breaker

Abstract

The determination of the kinematics parameters is presented in this paper by dynamic analysis of the operating mechanism. This mechanism achieve the displacement of the movable contact of the circuit breaker. The dynamic analysis is achieved for the operating mechanism of the middle voltage circuit breaker. The equation of motion for operating mechanism is a differential equation of order two. The numerical method Runge - Kutta of third order is applied to solve the equation of motion. The experimental results correspond to good values obtained by compute. Consequently, the proposed dynamic and mathematics models are verified by measurements.

În această lucrare este prezentată determinarea parametrilor cinematici prin analiza dinamică a mecanismului de acţionare. Acest mecanism realizează deplasarea contactului mobil al ruptorului electric de medie tensiune. Ecuaţia de mişcare a mecanismului de acţionare este o ecuaţie diferenţială de ordinul doi. Pentru a rezolva ecuaţia de mişcare a fost aplicată o metodă numerică Runge-Kutta de ordinul trei.
