| Summary: | The Ultra-High Voltage (UHV) Circuit Breaker (CB) is a protective device that applies power to the power system through close - open operations and ensures the stability of the system from breaking fault currents caused by ground fault, short-circuit, and other accidents. During close - open operation, the circuit breaker operates at high speed and generates a large dynamic force. Also, it is important to accurately evaluate the dynamic characteristics at the design stage because the dynamic characteristics have a great influence on the breaking performance. However, it is difficult to analyze exactly the dynamic characteristics due to the multi-physics condition in which the drive part of the UHV circuit breaker works in combination with mechanisms and fluid-elements. In this study, a co-simulation model of 1D system analysis program was developed based on 3D multi-body dynamics analysis program in order to obtain more accurate results for dynamic characteristics analysis of the drive part of UHV circuit breaker. Using this technique, the dynamic characteristics of UHV circuit breaker products were analyzed and the accuracy was verified. |
