通常,人们习惯地对单机容量100MW及以下的发电机组称为中小型发电机。鉴于我国能源综合利用开发的基本国策,自西部大开发以来,特别在西南地区,中小型水力发电机组建设拔地而起,产业结构也已具备了一定的规模,随着市场经济的发展,对于中小型水力发电机保护断路器的设计选型,改变以往使用通用型断路器为发电机型断路器的传统,已是大势所趋。 Generally, people are often referred to small and medium-sized generators for generator sets with a single unit capacity of 100 MW and below. In view of the basic national policy of comprehensive utilization of energy in our country, since the large-scale development of the western region, especially in the southwestern region, the construction of small and medium-sized hydropower units has been built up. The industrial structure has also reached a certain scale. With the development of market economy, Small and medium-sized hydro-generator circuit breaker design selection, change the general use of conventional circuit breaker for the generator-type circuit breaker has become the trend of the times.
