Abstract:
According to the operating conditions and characteristics of a 40.5kV switchgear, a novel vacuum load-disconnection switch is presented and its operating mechanism is analyzed in detail. The theory of mechanical principle is adopted for kinematics and dynamics analysis of actuator, so the characteristics of the movement of actuator settle for the electrical parameters of vacuum load- disconnection switch. Meanwhile the mathematical model is set up for the optimum calculation with MATLAB. By the optimization results, the actual actuator and test platform are established and the mechanical and electrical properties of the switch are measured. All results are verified by type approval test. The results show that its structure is simple and its assembly is facilitated. Its parameters meet the characteristics of vacuum interrupters. Furthermore, this device has some advantages, such as higher reliability, higher stability, convenience of operation, and so on. Meanwhile, the method of design and analysis for operating mechanism is feasible. |
