Optimization ova Mechanism for Power Transfer Breakers
전력변환차단기의 트리거 기구 최적화
Abstract
PTB(Power Transfer Breaker) is a device which incorporate the functions of ACB(Air Circuit Breaker) and ATS(Automatic Transfer Switch). ACB is a circuit breaker against overload and ATS is a switching device to transfer the load between two electric power sources. An existing PTB design based upon the 5 bar & cam mechanism has been regarded to be too complex and thus a simpler 4 bar mechanism with trigger lock is proposed. Experimentation and optimization of the trigger lock is presented.
