介绍大学电类大学生开放式实验室设计的新思路,主要包含有市电和柴油发电电源的切换,各种接地系统的介绍,二,三级配电系统和保护及用电终端使用方法。力求让学生通过实验室的实践,加深对工厂供配电、电气安全、各种接地系统以及用电注意事项的理解,达到理论和实践的统一。 This paper introduces the new idea of ​​university open laboratory design for electrical students. It mainly includes the switching of utility power and diesel power generation, the introduction of various grounding systems, the secondary and tertiary distribution systems, and the terminal protection and usage methods. Trying to make students through the practice of the laboratory to deepen the understanding of the factory for power distribution, electrical safety, a variety of grounding systems and electrical considerations, to achieve the unity of theory and practice.
