摘要
低压断路器在配电系统中起着十分重要的作用,低压断路器保护特性的实验加深了学生对理论知识的理解,锻炼了动手能力。讨论了低压断路器的工作原理和保护特性,设计了断路器保护特性实验的方法和基本原理图,并给出了实验主要设备的详细参数。教学实践表明,上述实验系统满足了教学要求,达到预期效果。
students to protection Low voltage circuit breakers take an important role in low voltage electrical distribution systems. It can help understand the theory of electrical apparatus and improve their practical ability, through experiments on the characteristics of low-voltage circuit breaker. In this paper, the principles of operation and protection characteristics of low voltage circuit breaker were discussed. The experimental method and schematic diagram of protection characteristics experiment of low voltage circuit breaker were introduced, with the parameters of main equipments given. The experimental teaching results show the experiment system meets the demand of the specialized course, and takes effect very well.
