The rearch and applcation of breaker power reducing in transmission and distribution system

摘要

Transmission and distribution system energy consumption can be influenced by various factors, such as distribution iron loss, copper loss , electromotor iron loss, electromotor copper loss, generatrix (cable) copper loss, and the loss of distributing electricity, protecting transformer ,protecting current collector breaker in distribution network. The authors of this paper have a long histroy in dealing with low-voltage R&D. Based on this situation, they develop new structure to lower the energy consumption after long-term rearch and analyse about breaker energy consumption, fortunately, they put our research into use with realistic meaning.
